My Top Tips To Help Your Family Stay Safe Online This Holiday Period

By Alex Merton-McCann

It’s the most wonderful time of year’ – we’ve all heard the jingles and read the slogans. But the holiday season can also be a little overwhelming when you’re the one ‘in charge’. Whether it’s prepping for the inevitable influx of new devices, buying the gifts or booking the holiday – there are a lot of online safety considerations to workshop in addition to how you’re going to stuff the turkey and decorate the tree! 

So, with the Christmas spirit running through my keyboard, I hereby share with you my top tips to help you keep you and your family safe online this holiday period. 

1. Have a Safety Plan for ALL New Devices 

We all know that Santa loves technology so it’s inevitable that your family members may find a new device or two under the tree this year. So, as soon as they have unboxed their shiny new item, I recommend on insisting on a few steps to both protect the device and its new owner: 

  • Change the default passcode or set up a new one immediately 
  • Check for software updates – these ensure that any bugs or weak spots are addressed 
  • Choose a ‘back-up’ solution. If it’s an iPhone, iCloud can work. I’m a fan of Dropbox as it works so well on both phones and laptops. 
  • Invest in a security solution. If you already have a premium subscription to an online security solution like McAfee+ then you’ll likely be able to add the new devices (phones, tablets or laptops) to your family plan. If not, consider investing. Not only will it protect devices from viruses and phishing attacks, but it will also help you locate it if it ever gets misplaced- very common occurrence in my household!      

2. Online Shopping 

Getting to the bottom of the Christmas gift list takes time particularly if you are ‘lucky’ enough to get COVID before Christmas, like myself! While there are still some retailers guaranteeing delivery before Christmas – including Amazon until Christmas Eve (phew!) – you might need to focus on gift cards if you don’t want to face the hordes at the shops. Regardless of what you buy, please follow the following online shopping tips to avoid being cyberscrooged this year: 

  • Only buy from trusted retailers – even if it costs a few more dollars 
  • Ensure the site is secure – look for a padlock at the start of a web address and an address that starts with ‘https’ 
  • Avoid offers that are ‘too good to be true’ – they usually are! 
  • Don’t ever use public Wi-Fi to do your shopping – no exceptions! 

3. Book Your Holiday From a Reputable Online Site 

I don’t think there would be anything more disappointing than anticipating a holiday only to have it not happen. Or, to be scammed while preparing for it. With holiday makers having to jump through more hoops thank to COVID requirements, many experts are predicting scammers will be turning their attention to creating fake COVID verification sites, designed purely to extract personal details from unsuspecting holiday makers. So, if you’re booking a holiday, or doing your admin for it, please do the following: 

  • Take a moment to verify – check the website URL to ensure it leads to where you expect before clicking and paying. And always verify the validity of any requests for payment. Contact your travel retailer if you have any concerns. 
  • Think before you click – make sure the site is secure before you pay: check that the URL has a visible padlock in the search bar and that it starts with an ‘https’. 
  • Using BPay or PayID is also another good way to protect yourself. Both these platforms will show customers who they are paying before they ‘do the deal’ which reduces the chance of being scammed. 

4. Be Careful What You Share Online 

With so many of us busting with excitement to be travelling this holiday season for the first time in a few years, it’s inevitable that we want to share online. But, please think before you post. Checking in to airports or hotels online is really a way of alerting the online world to the fact that your house is likely unattended! And please make sure your kids understand this too. I appreciate there’s a lot of kudos for sharing holidays snaps in the moment but encourage your offspring to wait until you get home before sharing. Here are my top tips: 

  • No checking in online anywhere 
  • No sharing pics of Christmas gifts 
  • Only share holiday snaps once you’ve arrived back home 

And if you’re feeling a little overwhelmed, why not make yourself a cuppa and harness the power of technology. Make yourself a to-do list on Todoist or Google Docs, send out ecards if you absolutely can’t disappoint key family and friends – loving the options from Greetings Island, buy some gift cards from Prezee or The Gift Cards Store then design your Christmas Day menu with the help of Taste or RecipeTinEats. And voila you’re done!  

PS Just remember to create unique passwords if you choose to set up accounts with any new sites! 

Happy Holidays Everyone!!!

Integrating Security

As the needs of Black Hat evolved, so did the Cisco Secure Technologies in the NOC:

The SecureX dashboard made it easy to see the status of each of the connected Cisco Secure technologies.

Since joining the Black Hat NOC in 2016, my goal remains integration and automation. As a NOC team comprised of many technologies and companies, we are pleased that this Black Hat NOC was the most integrated to date, to provide an overall SOC cybersecurity architecture solution.

We have ideas for even more integrations for Black Hat Asia and Black Hat USA 2023. Thank you, Piotr Jarzynka, for designing the integration diagram.

Below are the SecureX threat response integrations for Black Hat Europe, empowering analysts to investigate Indicators of Compromise very quickly, with one search.

The original Black Hat NOC integration for Cisco was NetWitness sending suspicious files to Threat Grid (know Secure Malware Analytics). We expanded that in 2022 with Palo Alto Networks Cortex XSOAR and used it in London, for investigation of malicious payload attack.

NetWitness observed a targeted attack against the Black Hat network. The attack was intended to compromise the network.

NetWitness extracted the payload and sent it to Secure Malware Analytics for detonation.

Reviewing the analysis report, we were able to quickly determine it was the MyDoom worm, which would have been very damaging.

The attack was blocked at the perimeter and the analysts were able to track and enrich the incident in XSOAR.

First Time at Black Hat, by Jérémy Couture, Head of SOC, Paris 2024 Olympic Games

My first time at Black Hat turned out to be an incredible journey!

Thanks to the cybersecurity partnership between Paris 2024 and Cisco, I was able to integrate into the Cisco Crew, to operate the NOC/SOC as a Threat Hunter on the most dangerous network in the world for this European Edition of Black Hat.

My first day, I helped with deploying the network by installing the wireless Meraki APs on the venue, understanding how they were configured and how they could help analysts to identify and locate any client connected to the network that could have a bad behavior during the event, the idea being to protect the attendees if an attack was to spray on the network.

Following this “physical” deployment, I’ve been able to access the whole Cisco Secure environment including Meraki, Secure Malware Analytics, Umbrella, SecureX and the other Black Hat NOC partners software tools.

SecureX was definitely the product on which I wanted to step up. By having so fantastic professionals around me, we were able to dig in the product, identifying potential use cases to deploy in the orchestration module and expected integrations for Paris 2024.

Time was flying and so were the attendees to the conference, a network without user is fun but can be quite boring as nothing happens, having so many cybersecurity professional at the same place testing different security malwares, attacks and so on led us to very interesting investigations. A paradox at the Black Hat, we do not want to block malicious content as it could be part of exercises or training classes, quite a different mindset as what we, security defenders, are used to! Using the different components, we were able to find some observables/IOCs that we investigate through SecureX, SecureX being connected to all the other components helped us to enrich the observables (IPs, urls, domains…), understanding the criticality of what we identified (such as malware payloads) and even led us to poke the folks in the training classes to let them know that something really wrong was happening on their devices.

Being part of the Black Hat NOC was an incredible experience, I was able to meet fantastic professionals, fully committed on making the event a success for all attendees and exhibitors. It also helped me to better understand how products, that we use or will use within Paris 2024, could be leveraged to our needs and which indicators could be added to our various Dashboards, helping us to identify, instantaneously, that something is happening. 

Trojan on an Attendee Laptop, by Ryan MacLennan

During the last day of Black Hat Europe, our NOC partner, NetWitness saw some files being downloaded on the network. The integration again automatically carved out the file and submitted the Cisco Secure Malware Analytics (SMA) platform. One of those files came back as a trojan, after SMA detonated the file in a sandbox environment. The specific hash is the below SHA-256:

938635a0ceed453dc8ff60eab20c5d168a882bdd41792e5c5056cc960ebef575

The screenshot below shows some of the behaviors that influenced the decision:

The result of seeing these behaviors caused SMA to give it the highest judgement score available to a detonated file:

After this judgement was made, we connected with the Palo Alto Networks team, and they found the IP address associated with the file download.

Once we had this information, we went to the Meraki dashboard and did a search for the IP address. The search returned only one client that has been associated with the address for the entire Black Hat conference.

Knowing that there has only been one client associated with the address made finding the attendee easier. We then needed to know where they were and Meraki had this figured out. After opening the client’s profile, we saw what SSID and access point (AP) they were connected to using the Meraki location map.

We then found the attendee and let them know to have their IT inspect their laptop to make sure it is clean.

Apart from the technical challenges of running a temporary network for N thousand people, the Black Hat event reminded us that success doesn’t happen without teamwork; that leadership isn’t just about keeping the project on track. It is also about looking after the team and that small details in planning, build up and tear down can be just as important, as having all the right tools and fantastically skilled Individuals using them during the event itself.

Automated Account Provisioning, by Adi Sankar

In the Cisco Secure technology stack, within the Black Hat NOC, we use SecureX Single Sign-on. This reduces the confusion of managing multiple accounts and passwords. It also streamlines the integrations between the Cisco products and our fellow NOC partners. We have an open ecosystem approach to integrations and access in the NOC, so we will provision Cisco Secure accounts for any staff member of the NOC. Logging into each individual console and creating an account is time consuming and can often lead to confusion on which tools to provision and which permission levels are needed.

To automate this process, I developed two workflows: one to create non-admin users for NOC partners and one to create administrator accounts in all the tools for Cisco staff. The workflows create accounts in SecureX, Secure Malware Analytics (Threat Grid), Umbrella DNS and Meraki dashboard, all using SecureX Single Sign-On.

Here is what the workflow looks like for creating non-admin users.

The workflow requires three inputs: first name, last name, and email. Click Run.

The sequence of API calls is as follows:

  • Generate a SecureX token to access the SecureX API including the “admin/invite:write, invite:write” scopes.
  • Invite the User to SecureX using the invite API (https://visibility.amp.cisco.com/iroh/invite/index.html#/). In the body of this POST the role is set to “user”. In the Administrator workflow this would be set to “admin” allowing full access to SecureX.
  • If the invite fails due to a duplicate invite, print an error message in Webex teams.
  • Invite the user to the Meraki dashboard using the “admins” API (https://api.meraki.com/api/v1/organizations/{organizationId}/admins). In the body of this call, the organization access is set to none, and access to two networks (Wireless network and Systems Manager) are set to “read-only” to ensure the user cannot make any changes to affect the network. In the Administrator version org access is still set to none but “full” permissions are provided to the two networks, something we do not want all users to have.
  • Generate a token to the new Umbrella API using https://api.umbrella.com/auth/v2/token with the following scopes (read admin users, write admin users, read admin roles). This single endpoint for generating a token based on scopes has made using the Umbrella API significantly easier.
  • Then invite the user to Umbrella using the “admins” API at (https://api.umbrella.com/admin/v2/users) and in the body of this POST the “role ID” is set to 2 to ensure read-only permissions are provisioned for Umbrella.
  • Create a user in Secure Malware analytics using the API at (https://panacea.threatgrid.com/api/v3/organizations/<ORG_ID>/users). The body of this request simply creates a Malware Analytics login using the users last name and appending “_blackhat”
  • The last call is to send a password reset email for the Malware Analytics user. (https://panacea.threatgrid.com/api/v3/users/<LOGIN>/password-email) They can set their password via the email, login to the Malware Analytics console and then link their SecureX sign-on account, which means they will no longer need to use their Malware Analytics credentials.

Once the workflow has completed successfully, the user will receive four emails to create a SecureX Sign-On account and accept the invitations to the various products. These workflows really improved our responsiveness to account provisioning requests and makes it much easier to collaborate with other NOC partners.

Integrating Meraki Scanning Data with Umbrella Security Events, by Christian Clasen

Over the previous Black Hat events, we have been utilizing Meraki scanning data to get location data for individual clients, as they roamed conference. In the initial blog post (Black Hat Asia 2022), we created a Docker container to accept the data from the Meraki Scanning API and save it for future analysis. At Black Hat USA 2022, we wrote about how to use Python Folium to use the flat text files to generate chronological heatmaps that illustrated the density of clients throughout the conference.

This time around, we’ve stepped it up again by integrating Umbrella DNS Security events and adding the ability to track clients across the heatmap using their local IP address.

To improve the portability of our data and the efficiency of our code, we began by moving from flat JSON files to a proper database. We chose SQLite this time around, though going forward we will likely use Mongo.

Both can be queried directly into Python Pandas dataframes which is what will give us the optimal performance we are looking for. We have a dedicated Docker container (Meraki-Receiver) that will validate the incoming data stream from the Meraki dashboard and insert the values into the database.

The database is stored on a Docker volume that can be mounted by our second container, the Meraki-Mapper. Though this container’s primary purpose is building the heatmaps, it also performs the task of retrieving and correlating Umbrella DNS security events. That is, any DNS query from the Black Hat network that matches one of several predefined security categories. Umbrella’s APIs were recently improved to add OAuth and simplify the URI scheme for each endpoint. After retrieving a token, we can get all security events in the time frame of the current heatmap with one call.

What we want to do with these events is to create Folium Markers. These are static “pins” that will sit on the map to indicate where the DNS query originated from. Clicking on a marker will popup more information about the query and the client who sent it.

Thanks to the Umbrella Virtual Appliances in the Black Hat network, we have the internal IP address of the client who sent the DNS query. We also have the internal IP address in the Meraki scanning data, along with the latitude and longitude. After converting the database query into a Pandas dataframe, our logic takes the IP address from the DNS query and finds all instances in the database of location data for that IP within a 5-minute window (the resolution of our heatmap).

What we end up with is a list of dictionaries representing the markers we want to add to the map. Using Bootstrap, we can format the popup for each event to make it look a bit more polished. Folium’s Popup plugin allows for an iFrame for each marker popup.

The result is a moving heatmap covering an entire day on a given conference floor, complete with markers indicating security events (the red pushpin icon).

Clicking on the pushpin shows the details of the query, allowing us in the NOC to see the exact location of the client when they sent it.

To further improve this service during the next conference, we plan to implement a web page where NOC staff can submit an IP address and immediately get map tracking that client through the conference floor. This should give us an even more efficient way to find and notify folks who are either behaving maliciously or appear to be infected.

Domain Name Service Statistics, by Adi Sankar

For years we have been tracking the DNS stats at the Blackhat conferences. The post-pandemic 2022 numbers look like we never skipped a beat after the dip in DNS queries from 2021, seen in the bar graph below. This year’s attendance saw well over 11 million total DNS queries.

The Activity volume view from Umbrella gives a top-level level glance of activity by category, which we can drill into for deeper threat hunting. On trend with the previous Black Hat Europe events, the top Security categories were Dynamic DNS and Newly Seen Domains. However, it’s worth noting a proportionally larger increase in the cryptomining and phishing categories from 9 to 17 and 28 to 73, respectively, compared to last year.

These years, Black Hat saw over 4,100 apps connect to the network, which is nearly double of what was seen last year. However, still not topping over 6,100 apps seen at Black Hat USA early this year.

Should the need arise, we can block any application, such as Mail.ru above.

Black Hat Europe 2022 was the best planned and executed NOC in my experience, with the most integrations and visibility. This allowed us the time to deal with problems, which will always arise.

We are very proud of the collaboration of the team and the NOC partners.

Black Hat Asia will be in May 2023, at the Marina Bay Sands, Singapore…hope to see you there!

Black Hat Europe 2022 NOC: When planning meets execution

By Jessica Bair

In this blog about the design, deployment and automation of the Black Hat network, we have the following sections:

  • Designing the Black Hat Network, by Evan Basta
  • AP Placement Planning, by Sandro Fasser
  • Wi-Fi Air Marshal, by Jérémy Couture, Head of SOC, Paris 2024 Olympic Games
  • Meraki Dashboards, by Rossi Rosario Burgos

  • A Better Way to Design Training SSIDs/VLANs, by Paul Fidler

Cisco is honored to be a Premium Partner of the Black Hat NOC, and is the Official Network Platform, Mobile Device Management, Malware Analysis and DNS (Domain Name Service) Provider of Black Hat.

2022 was Cisco’s sixth year as a NOC partner for Black Hat Europe. However, it was our first time building the network for Black Hat Europe. We used experiences of Black Hat Asia 2022 and Black Hat USA 2022 to refine the planning for network topology design and equipment. Below are our fellow NOC partners providing hardware, to build and secure the network, for our joint customer: Black Hat.

Designing the Black Hat Network, by Evan Basta

We are grateful to share that Black Hat Europe 2022 was the smoothest experience we’ve had in the years at Black Hat. This is thanks to the 15 Cisco Meraki and Cisco Secure engineers on site (plus virtually supporting engineers) to build, operate and secure the network; and great NOC leadership and collaborative partners.

To plan, configure, deploy (in two days), maintain resilience, and recover (in four hours) an enterprise class network, took a lot of coordination. We appreciate the Black Hat NOC leadership, Informa and the NOC partners; meeting each week to discuss the best design, staffing, gear selection and deployment, to meet the unique needs of the conference. Check out the “Meraki Unboxed” podcast – Episode 94: Learnings from the Black Hat Europe 2022 Cybersecurity Event

We must allow real malware on the Black Hat network: for training, demonstrations, and briefing sessions; while protecting the attendees from attack within the network from their fellow attendees, and prevent bad actors from using the network to attack the Internet. It is a critical balance to ensure everyone has a safe experience, while still being able to learn from real world malware, vulnerabilities, and malicious websites.

In addition to the weekly meetings with Black Hat and the other partners, the Cisco Meraki engineering team of Sandro Fasser, Rossi Rosario Burgos, Otis Ioannou, Asmae Boutkhil, Jeffry Handal and I met every Friday for two months. We also discussed the challenges in a Webex space with other engineers who worked on past Black Hat events.

The mission:

Division of labor is essential to reduce mistakes and stay laser focused on security scope. Otis took the lead working on network topology design with Partners. Asmae handled the port assignments for the switches. Rossi ensured every AP and Switch was tracked, and the MAC addresses were provided to Palo Alto Networks for DCHP assignments. Otis and Rossi spent two days in the server room with the NOC partners, ensuring every switch was operating and configured correctly. Rossi also deployed and configured a remote Registration switch for Black Hat.

AP Placement Planning, by Sandro Fasser

In the weeks before deployment, our virtual Meraki team member, Aleksandar Dimitrov Vladimirov, and I focused on planning and creating a virtual Wi-Fi site survey. Multiple requirements and restrictions had to be taken into consideration. The report was based on the ExCel centre floor plans, the space allocation requirements from Black Hat and the number of APs we had available to us. Although challenging to create, with some uncertainties and often changing requirements due to the number of stakeholders involved, the surveys AP placement for best coverage ended up being pivotal at the event.

Below is the Signal Strength plan for the Expo Hall Floor on the 5 GHz band. The original plan to go with a dual-Band deployment was adjusted onsite and the 2.4 GHz band was disabled to enhance performance and throughput. This was a decision made during the network setup, in coordination with the NOC Leadership and based on experience from past conferences.

Upon arrival at the ExCel Centre, we conducted a walkthrough of the space that most of us had only seen as a floor plan and on some photos. Thanks to good planning, we could start deploying the 100+ APs immediately, with only a small number of changes to optimize the deployment on-site. As the APs had been pre-staged and added to the Meraki dashboard, including their location on the floor maps, the main work was placing and cabling them physically. During operation, the floor plans in the Meraki Dashboard were a visual help to easily spot a problem and navigate the team on the ground to the right spot, if something had to be adjusted.

As the sponsors and attendees filled each space, in the Meraki dashboard, we were able to see in real-time the number of clients connected to each AP, currently and over the time of the conference. This enabled quick reaction if challenges were identified, or APs could be redeployed to other zones. Below is the ExCel Centre Capital Hall and London Suites, Level 0. We could switch between the four levels with a single click on the Floor Plans, and drill into any AP, as needed.

The Location heatmaps also provided essential visibility into conference traffic, both on the network and footfalls of attendees. Physical security is also an important aspect of cybersecurity; we need to know how devices move in space, know where valuable assets are located and monitor their safety.

Below is the Business Hall at lunchtime, on the opening day of the conference. You can see no live APs in the bottom right corner of the Location heatmap. This is an example of adapting the plan to reality onsite. In past Black Hat Europe conferences, the Lobby in that area was the main entrance. Construction in 2022 closed this entrance. So, those APs were reallocated to the Level 1 Lobby, where attendees would naturally flow from Registration.

The floor plans and heatmaps also helped with the Training, Briefings and Keynote network resilience. Capacity was easy to add temporarily, and we were able to remove it and relocate it after a space emptied.

Meraki API Integration for automatic device blocking

During our time in the NOC, we had the chance to work with other vendor engineers and some use cases that came up led to interesting collaborations. One specific use case was that we wanted to block wireless clients, that show some malicious or bad behavior, automatically after they have been identified by one of the SOC analysts on the different security platforms, in addition we wanted to show them a friendly warning page that guides them to the SOC for a friendly conversation.

The solution was a script that can be triggered thru the interfaces of the other security products and attaches a group policy thru the Meraki Dashboard, including a quarantine VLAN and a splash page, via the Meraki APIs. This integration was just one of the many collaboration bits that we worked on.

Wi-Fi Air Marshal, by Jérémy Couture, Head of SOC, Paris 2024 Olympic Games

During the first day of training, in the Meraki dashboard Air Marshal, I observed packet flood attacks, against we were able to adapt and remain resilient.

I also observed an AP spoofing and broadcast de-authentication attack. I was able to quickly identify the location of the attack, which was at the Lobby outside the Business Hall.  Should the attacks continue, physical security had the information to intervene. We also had the ability to track the MAC address throughout the venue, as discussed in Christian Clasen’s section in part two.

From our experiences at Black Hat USA 2022, we had encrypted frames enabled, blunting the attack.

Meraki Dashboards, by Rossi Rosario Burgos

The Meraki dashboards made it very easy to monitor the health of the network APs and Switches, with the ability to aggregate data, and quickly pivot into any switch, AP or clients.

Through the phases of the conference, from two days of pre-conference setup, to focused and intense training the first two days, and transition to the briefings and Business Hall, we were able to visualize the network traffic.

In addition, we could see the number of attendees who passed through the covered area of the conference, with or without connecting to the network. Christian Clasen takes this available data to a new level in Part 2 of the blog.

As the person with core responsibilities for the switch configuration and uptime, the Meraki dashboard made it very simple to quickly change the network topology, according to the needs of the Black Hat customer.

Meraki Systems Manager, by Paul Fidler

If you refer back to Black Hat USA 2022, you’d have seen that we had over 1,000 iOS devices to deploy, with which we had several difficulties. For context, the company that leases the devices to Black Hat doesn’t use a Mobile Device Management (MDM) platform for any of their other shows…Black Hat is the only one that does. So, instead of using a mass deployment technology, like Apple’s Automated Device Enrollment, the iOS devices are “prepared” using Apple Configurator. This includes uploading a Wi-Fi profile to the devices as part of that process. In Las Vegas, this Wi-Fi profile wasn’t set to auto join the Wi-Fi, resulting in the need to manually change this on 1,000 devices. Furthermore, 200 devices weren’t reset or prepared, so we had those to reimage as well.

Black Hat Europe 2022 was different. We took the lessons from US and coordinated with the contractor to prepare the devices. Now, if you’ve ever used Apple Configurator, there’s several steps needed to prepare a device. However, all of these can be actions can be combined into a Blueprint:

Instead of there being several steps to prepare a device, there is now just one! Applying the Blueprint!

For Black Hat Europe, this included:

  • Wi-Fi profile
  • Enrollment, including supervision
  • Whether to allow USB pairing
  • Setup Assistant pane skipping

There’s lots of other things that can be achieved as well, but this results in the time taken to enroll and set up a device to around 30 seconds. Since devices can be set up in parallel (you’re only limited by the number of USB cables / ports you have), this really streamlines the enrollment and set up process.

Now, for the future, whilst you can’t Export these blueprints, they are transportable. If you open Terminal on a Mac and type:
cd /Users/<YOUR USER NAME>/Library/Group Containers/K36BKF7T3D.group.com.apple.configurator/Library/Application Support/com.apple.configurator/Blueprints

You’ll see a file / package called something.blueprint This can be zipped up and emailed to some else so, they can then use the exact same Blueprint! You may need to reboot your computer for the Blueprint to appear in Apple Configurator.

Device Naming / Lock Screen Messages

As mentioned, the registration / lead capture / session scanning devices are provided by the contractor. Obviously, these are all catalogued and have a unique device code / QR code on the back of them. However, during setup, any device name provisioned on the device gets lost.

So, there’s three things we do to know, without having to resort to using the unwieldy serial number, what devices is what.

  • The first thing that we do is to use the Meraki API to rename Systems Manager Devices. The script created has some other functionality too, such as error handling, but it is possible to do this without a script. You can find it here. This ensures that the device has a name: iOS devices default to being called iPhone or iPad in Systems Manager when they first enroll, so, already, this is incredibly helpful.
  • The second thing we do is to use a simple Restrictions profile for iOS, which keeps the physical device’s name in sync with that in the dashboard
  • Lastly, we then use a Lock Screen payload to format the message on the device when it’s locked:

In the footnote, you’ll see Device Name and Device Serial in blue. This denotes that the values are actually dynamic and change per device. They include:

  • Organization name
  • Network name
  • Device name
  • Device serial
  • Device model
  • Device OS version
  • Device notes
  • Owner name
  • Owner email
  • Owner username
  • SM device ID

On the Lock Screen, it’s now possible to see the device’s name and serial number, without having to flip the device over (A problem for the registration devices which are locked in a secure case) or open systems preferences.

We also had integration with SecureX device insights, to see the security status of each iOS device.

With the ability to quickly check on device health from the SecureX dashboard.

 

Data Security

This goes without saying, but the iOS devices (Registration, Lead Capture and Session Scanning) do have access to personal information. To ensure the security of the data, devices are wiped at the end of the conference. This is incredibly satisfying, hitting the Erase Devices button in Meraki Systems Manager, and watching the 100+ devices reset!

A Better Way to Design Training SSIDs/VLANs, by Paul Fidler

Deploying a network like Black Hat takes a lot of work, and repetitive configuration. Much of this has been covered in previous blogs. However, to make things easier for this event, instead of the 60 training SSIDs we had in Black Hat US 2022, the Meraki team discussed the benefits of moving to iPSKs with Black Hat NOC Leadership, which accepted the plan.

For context, instead of having a single pre shared key for an SSID, iPSK functionality allows you to have 1000+. Each of these iPSKs can be assigned its own group policy / VLAN. So, we created a script:

  • That consumed networkID, SSID, Training name, iPSK and VLAN from a CSV
  • Created a group policy for that VLAN with the name of the training
  • Created an iPSK for the given SSID that referred to the training name

This only involves five API calls:

  • For a given network name, get the network ID
  • Get Group Policies
  • If the group policy exists, use that, else create a group policy, retaining the group policy ID
  • Get the SSIDs (to get the ID of the SSID)
  • Create an iPSK for the given SSID ID

The bulk of the script is error handling (The SSID or network doesn’t exist, for example) and logic!

The result was one SSID for all of training: BHTraining, and each classroom had their own password. This reduced the training SSIDs from over a dozen and helped clear the airwaves.

The Best Way To Protect Your Online Identity

By Alex Merton-McCann

For many Aussies, identity theft was always something that happened to other people. People on TV, usually. But the recent spate of data breaches at Optus, Medibank and Energy Australia has made many of us pay far more attention than ever to one of the fastest growing crimes in our country.  

According to the Department of Home Affairs, 1 in 4 Aussies will be the victim of identity theft over the course of their lives with an annual economic impact of more than $2 billion. And with the financial fallout from the recent data breaches only just starting to be counted, these statistics will no doubt increase dramatically next year. 

What Actually Is Identity Theft? 

Identity theft is when a cybercriminal gains access to your personal information to steal money or gain other benefits. Armed with your personal info, they can apply for real identity documents in your name but with another person’s photograph. This enables them to then apply for loans or benefits in your name, sign up for memberships or even apply for credit cards. 

And it goes without saying that the financial and emotional fallout from identity theft can be huge. Since the Optus and Medibank hacking stories broke just a few months ago, there has been multiple stories of Aussie families who have had their identities stolen and who are in a world of pain. This Melbourne family who have had over $40,000 stolen from ATM withdrawals alone is just one example. 

What Do You Mean By Personal Information? 

Your personal information is any piece of information or data that can confirm who you are or how to find you. It may be a single piece of information, or several pieces used together. It’s often referred to as personally identifiable information (PII). So, it includes your name, parents’ name, address, date of birth, phone numbers, email address, usernames/passwords or passphrases, bank account details, school or university attended, location check-ins even RSVPS for events. 

Every time you register with a new shopping site or social media platform, you will be asked to share some personally identifiable information. However, what you share may be stolen or even misused – just think about the recent list of Australian companies who had their customers’ private information stolen by hackers. So that’s why you need to ensure you are only sharing your information with trusted online sites and take every possible step to protect your personal information online. 

How To Protect Your Online Identity 

While there are no guarantees in life, there are steps you can take to ensure your online identity is as safe as possible. Here are my top 5 tips: 

1. Use Multi-Factor Authentication When It’s Offered – Always! 

Multi-Factor Authentication (MFA) or 2 Factor Authentication (2FA) is a no-brainer because it makes a hacker’s life a lot harder. In short, it requires the user to provide two or more verification factors to gain access to an account or app. This might be a text, email or even a code generated by an authentication app. So, even if a hacker has your password and username, they still need that final piece of information before they can get their hands on your account! 

2. Use A Different (and Complex) Password On Every Account 

Now this may take a bit of work to set up but using a unique and complex password on every account is one of the best things you can do to protect your online identity. And here’s the rationale – if you use the same password on all your accounts and your login details are stolen then hackers have access to all the accounts that are accessed with that password. Yikes!!! So, a unique password for each account is a great measure. I love using a password manager to make this process a little easier. Not only do they generate complex passwords, but they remember them too! All you need to do is remember your Master Password which needs to be extremely complex!!! 

3. Keep Your Devices and Software Updated & Backed-Up 

Updates are most commonly about addressing security weaknesses. And yes, I know they can be a pain but if you ignore them, you are essentially making it easier for hackers to find their way into your life via weak spots. And don’t forget to ensure your security software remains updated too!   

I always recommend keeping a backup of all your important info in case something goes wrong. This should include all your photos, key documents and all your personally identifiable information. A hard drive works well but saving to the cloud is also a good option. I once dropped a hard drive and lost treasured family photos, so the cloud is my personal preference. 

4. Stay Ahead of The Threats – Invest in a Security & Identity Protection Solution  

We all know knowledge is power so investing in top notch security and identity monitoring software will help keep you ahead of threats. McAfee+, McAfee’s new all in one privacy, identity and device protection solution is a fantastic way for Aussies to protect themselves online. It features identity monitoring and a password manager but also an unlimited VPN, a file shredder, protection score and parental controls. And the Rolls Royce version called McAfee+ Advanced, also offers subscribers additional identity protections including access to licensed restoration experts who can help you repair your identity and credit, in case you’re affected by a data breach. It also gives subscribers access to lost wallet protection which help you cancel and replace your ID, credit cards if they are lost or stolen. 

5. Only Use Secure Wi-Fi or a VPN 

Public, unsecured Wi-Fi can make life so much easier when you’re out and about but it’s also a tried and tested way for scammers to access your personal information. Unsecured Wi-Fi is free Wi-Fi that is available in public places such as libraries, cafes, or shopping centres. So, instead of using Wi-Fi, just use the data in your phone plan. Or alternatively invest in a Virtual Private Network (VPN) that cleverly encrypts everything you share on your device.   

About 2 months ago, I embarked on a project to clean up my online life. I’m working through the list of sites I have accounts with and am closing those I no longer use, I’m also doing a huge password audit to ensure they are all unique to each site and are super complex, thanks to my password manager. Now, I’m not quite done yet, but things are in better shape than they were. Why not consider doing the same? With the holiday season fast approaching, why not dedicate a little of your poolside time to practicing a little cyber hygiene. 

 

Till next time, keep those identities safe!
