You’re not the only one looking forward to the big holiday sales like Black Friday and Cyber Monday. Hackers are too. As people flock to retailers big and small in search of the best deals online, hackers have their shopping scams ready. Remember, McAfee frees you to live your connected life safe from threats like viruses, malware, phishing, and more. Download award-winning antivirus that protects your data and devices today.
One aspect of cybercrime that deserves a fair share of attention is the human element. Crooks have always played on our feelings, fears, and misplaced senses of trust. It’s no different online, particularly during the holidays. We all know it can be a stressful time and that we sometimes give into the pressure of finding that hard-to-get gift that’s so hot this year. Crooks know it too, and they’ll tailor their attacks accordingly as we get wrapped up in the rush of the season.
So while you already know how to spot a great deal, here are ways you and your family can spot online shopping scams so you can keep your finances safer this shopping season:
A common scam hackers use is introducing malware via email attachments, and during the holiday sale season, they’ll often send malware under the guise of offering emails and shipping notifications. Know that retailers and shipping companies won’t send things like offers, promo codes, and tracking numbers in attachments. They’ll clearly call those things out in the body of an email instead.
A classic scammer move is to “typosquat” phony email addresses and URLs that look awfully close to legitimate addresses of legitimate companies and retailers. They often appear in phishing emails and instead of leading you to a great deal, these can in fact link you to scam sites that can then lift your login credentials, payment info, or even funds should you try to place an order through them. You can avoid these sites by going to the retailer’s site directly. Be skeptical of any links you receive by email, text, or direct message—it’s best to go to the site yourself by manually typing in the legitimate address yourself and look for the deal there.
A related scammer trick that also uses typosquatting tactics is to set up sites that look like they could be run by a trusted retailer or brand but are not. These sits may tout a special offer, a great deal on a hot holiday item, or whatnot, yet such sites are one more way cybercriminals harvest personal and financial information. A common way for these sites to spread is by social media, email, and other messaging platforms. Again a “close to the real thing” URL is a telltale sign of a copycat, so visit retailers directly. Also, comprehensive online protection software can prevent your browser from loading suspicious sites and warn you of suspicious sites in your search results.
While the best of them can look practically professional and be tough to spot, one way to avoid counterfeit shopping apps is to go to the source. Hit the retailer’s website on your mobile browser and look for a link to the app from their website. Likewise, stick to the legitimate app stores such as Google Play and Apple’s App Store. Both have measures in place to prevent malicious apps from appearing in their stores. Some can sneak through before being detected though, so look for the publisher’s name in the description and ensure it is legitimate. On a fake app, the name may be close to the retailer you’re looking for, but not quite right. Other signs of a fake will include typos, poor grammar, and design that looks a bit off.
At the heart of holiday shopping is scarcity. Special offers for a limited time, popular holiday items that are tough to find, and just the general preciousness of time during the season to get things done, like shopping. Scammers love this time of year. During the holidays, they’ll play on that scarcity and crunch you’re under in their offers and messaging. Enter the “too good to be true” offer, typically set up on phony sites like the ones mentioned above. If the pricing, availability, or delivery time all look too good to be true, it may be a scam designed to harvest your personal info and accounts. Use caution here before you click. If you’re unsure about a product or retailer, read reviews from trusted websites to help see if it’s legitimate.
Apart from spotting scams, there are several things you can do to keep yourself safer while shopping this holiday season. In fact, they can keep you safer when you shop year ‘round as well. Looking for a last minute deal? Download McAfee online protection today.
This is a great one to start with. Secure websites begin their address with “https,” not just “http.” That extra “s” in stands for “secure,” which means that it uses a secure protocol for transmitting sensitive info like passwords, credit card numbers, and the like over the internet. It often appears as a little padlock icon in the address bar of your browser, so double-check for that. If you don’t see that it’s secure, it’s best to avoid making purchases on that website.
Specific to the U.S., the Fair Credit Billing Act offers the public protection against fraudulent charges on credit cards, where citizens can dispute charges over $50 for goods and services that were never delivered or otherwise billed incorrectly. Note that many credit card companies have their own policies that improve upon the Fair Credit Billing Act as well. However, debit cards aren’t afforded the same protection under the Act. Avoid using those while shopping online and use your credit card instead.
Another alternative is to set up a virtual credit card, which is a proxy for your actual credit card. With each purchase you make, that proxy changes, which then makes it much more difficult for hackers to exploit. You’ll want to research virtual credit cards further, as there are some possible cons that go along with the pros, such as in the case of returns where a retailer will want to use the same proxy to reimburse a purchase.
Using a complete suite of online protection software can offer layers of extra protection while you shop, such as web browser protection and a password manager. Browser protection can block malicious and suspicious links that could lead you down the road to malware or a financial scam. A password manager can create strong, unique passwords and store them securely as well, making it far more difficult for hackers to compromise your accounts. Identity theft protection takes your safety a step further by helping you secure your identity online and restore it should any of your personal info be found in the wrong hands.
Two-factor authentication is an extra layer of defense on top of your username and password. It adds in the use of a special one-time-use code to access your account, usually sent to you via email or to your phone by text or a phone call. In all, it combines something you know, like your password, with something you have, like your smartphone. Together, that makes it tougher for a crook to hack your account. If any of your accounts support two-factor authentication, the few extra seconds it takes to set up is more than worth the big boost in protection you’ll get.
Public Wi-Fi in coffee shops and other public locations can expose your private surfing to prying eyes because those networks are open to all. Using a virtual private network (VPN) encrypts your browsing, shopping, and other internet traffic, thus making it secure from attempts at intercepting your data on public Wi-Fi and harvesting information like your passwords and credit card numbers.
With all the passwords and accounts we keep, this is important. Checking your credit will uncover any inconsistencies or outright instances of fraud. From there, you can then take steps to straighten out any errors or bad charges that you find. In the U.S., you can run a free credit report once a year with the major credit reporting agencies.
So while you’re shopping online this year, take a deep breath before you dive in. Double-check those deals that may look almost too good to be true. Look closely at those links. And absolutely don’t click on those attachments that look like shipping notices or coupon deals. Hackers are counting on you to be in a bit of a hurry this time of year. Taking an extra moment to spot their tricks can go a long way toward keeping you and your finances safe. Remember, stay ahead of cyber criminals, get an extra layer of protection with McAfee this holiday season.

At Black Hat USA 2020, Trend Micro presented two important talks on vulnerabilities in Industrial IoT (IIoT). The first discussed weaknesses in proprietary languages used by industrial robots, and the second talked about vulnerabilities in protocol gateways. Any organization using robots, and any organization running a multi-vendor OT environment, should be aware of these attack surfaces. Here is a summary of the key points from each talk.
Rogue Automation
Presented at Black Hat, Wednesday, August 5. https://www.blackhat.com/us-20/briefings/schedule/index.html#otrazor-static-code-analysis-for-vulnerability-discovery-in-industrial-automation-scripts-19523 and the corresponding research paper is available at https://www.trendmicro.com/vinfo/us/security/news/internet-of-things/unveiling-the-hidden-risks-of-industrial-automation-programming
Industrial robots contain powerful, fully capable computers. Unlike most contemporary computers, though, industrial robots lack basic information security capabilities. First, at the architectural level, they lack any mechanism to isolate certain instructions or memory. That is, any program can alter any piece of storage, or run any instruction. In traditional mainframes, no application could access, change, or run any code in another application or in the operating system. Even smartphone operating systems have privilege separation. An application cannot access a smartphone’s camera, for instance, without being specifically permitted to do so. Industrial robots allow any code to read, access, modify, or run any device connected to the system, including the clock. That eliminates data integrity in industrial robots and invalidates any audit of malfunctions; debugging becomes exceptionally difficult.
Industrial robots do not use conventional programming languages, like C or Python. Instead, each manufacturer provides its own proprietary programming language. That means a specialist using one industrial robot cannot use another vendor’s machine without training. There are no common information security tools for code validation, since vendors do not develop products for fragmented markets. These languages describe programs telling the robot how to move. They also support reading and writing data, analyzing and modifying files, opening and closing input/output devices, getting and sending information over a network, and accessing and changing status indicators on connected sensors. Once a program starts to run on an industrial robot, it can do anything any fully functional computer can do, without any security controls at all. Contemporary industrial robots do not have any countermeasures against this threat.
Most industrial robot owners do not write their own programs. The supply chain for industrial robot programs involves many third-party actors. See Figure 1 below for a simplified diagram. In each community, users of a particular vendor’s languages share code informally, and rely on user’s groups for hints and tips to solve common tasks. These forums rarely discuss security measures. Many organizations hire third-party contractors to implement particular processes, but there are no security certifications relevant to these proprietary languages. Most programmers learned their trade in an air-gapped world, and still rely on a perimeter which separates the safe users and code inside from the untrusted users and code outside. The languages offer no code scanners to identify potential weaknesses, such as not validating inputs, modifying system services, altering device state, or replacing system functions. The machines do not have a software asset management capability, so knowing where the components of a running program originated from is uncertain.

All is not lost – not quite. In the short term, Trend Micro Research has developed a static code analysis tool called OTRazor, which examines robotic code for unsafe code patterns. This was demonstrated during our session at Black Hat.
Over time, vendors will have to introduce basic security checks, such as authentication, authorization, data integrity, and data confidentiality. The vendors will also have to introduce architectural restrictions – for instance, an application should be able to read the clock but not change it.. Applications should not be able to modify system files, programs, or data, nor should they be able to modify other applications. These changes will take years to arrive in the market, however. Until then, CISOs should audit industrial robot programs for vulnerabilities, and segment networks including industrial robots, and apply baseline security programs, as they do now, for both internally developed and procured software.
Protocol Gateway Vulnerabilities
Presented at Black Hat, Wednesday, August 5, https://www.blackhat.com/us-20/briefings/schedule/index.html#industrial-protocol-gateways-under-analysis-20632, with the corresponding research paper available here: https://www.trendmicro.com/vinfo/us/security/news/internet-of-things/lost-in-translation-when-industrial-protocol-translation-goes-wrong.
Industry 4.0 leverages the power of automation alongside the rich layer of software process control tools, particularly Enterprise Resource Planning (ERP), and its bigger cousin, Supply Chain Management (SCM). By bringing together dynamic industrial process control with hyper-efficient “just-in-time” resource scheduling, manufacturers can achieve minimum cost, minimum delay, and optimal production. But these integration projects require that IIoT devices speak with other technology, including IIoT from other manufacturers and legacy equipment. Since each equipment or device may have their own communication protocol, Industry 4.0 relies heavily on protocol converters.
Protocol converters are simple, highly efficient, low-cost devices that translate one protocol into another. Protocol converters are ubiquitous, but they lack any basic security capabilities – authentication, authorization, data integrity or data confidentiality – and they sit right in the middle of the OT network. Attackers can subvert protocol converters to hijack the communication or change configuration. An attacker can disable a safety thresholds, generate a denial of service attack, and misdirect an attached piece of equipment.
In the course of this research, we found nine vulnerabilities and are working with vendors to remediate the issues. Through our TXOne subsidiary, we are developing rules and intelligence specifically for IIoT message traffic, which are then embedded in our current network security offerings, providing administrators with better visibility and the ability to enforce security policies in their OT networks.
Protocol converters present a broad attack surface, as they have limited native information security capabilities. They don’t validate senders or receivers, nor do they scan or verify message contents. Due to their crucial position in the middle of the OT network, they are an exceptionally appealing target for malicious actors. Organizations using protocol converters – especially those on the way to Industry 4.0 – must address these weak but critical components of their evolving infrastructure.
