This Week in Security News: Linkury Adware Caught Distributing Full-Blown Malware and Cross-Platform Modular Glupteba Malware Uses ManageX

By Jon Clay (Global Threat Communications)
week in security

Welcome to our weekly roundup, where we share what you need to know about the cybersecurity news and events that happened over the past few days. This week, learn about how an adware family known primarily for distributing browser hijackers, Linkury, has been caught distributing malware. Also, read about a newly uncovered strain of the Glupteba trojan.

 

Read on:

Cross-Platform Modular Glupteba Malware Uses ManageX

Trend Micro recently encountered a variant of the Glupteba trojan and reported its attacks on MikroTik routers and updates on its command and control (C&C) servers. The use of ManageX, a type of modular adware that Trend Micro has recently analyzed, is notable in this newly uncovered strain as it aims to emphasize the modularity and the cross-platform features of Glupteba as seen through its code analysis.

Phishing Attack Targets Microsoft 365 Users with Netflix & Amazon Lures

Security researchers have been tracking a phishing campaign that abuses Microsoft Office 365 third-party application access to obtain specific resources from victims’ accounts. The attacker, dubbed TA2552, mostly uses Spanish-language lures and a narrow range of themes and brands. These attacks have targeted organizations with a global presence but seem to choose victims who likely speak Spanish, according to a report from Proofpoint researchers.

New Report Suggests the Bug Bounty Business is Recession-Proof

A new report from HackerOne presents data suggesting that the bug bounty business might be recession-proof, citing increases in hacker registrations, monthly vulnerability disclosures and payouts during a pandemic-induced economic downturn. Brian Gorenc, senior director of vulnerability research and director of Trend Micro’s Zero Day Initiative program, shared that he’s seen bug bounty activity increase with ZDI publishing 1,045 vulnerability advisories in all of 2019 and 1,235 already in 2020.

Identity Fraud: How to Protect Your Identity Data, Accounts and Money During the Coronavirus Crisis

We’ve all been spending more time online since the pandemic hit, and as a result we’re sharing more personal and financial information online with each other and with organizations. Unfortunately, as ever, there are bad guys around every digital corner looking for this. Personally identifiable information (PII) is the currency of internet crime, and cyber-criminals will do whatever they can to get it.

Linkury Adware Caught Distributing Full-Blown Malware

An adware family known primarily for distributing browser hijackers has been caught distributing malware, security researchers said at the Virus Bulletin 2020 security conference. Its main method of distribution is the SafeFinder widget, a browser extension ironically advertised as a way to perform safe searches on the internet. K7 researchers say that in recent cases they analyzed, the SafeFinder widget has now also begun installing legitimate malware, such as the Socelars and Kpot infostealer trojans.

Chinese APT Group Targets Media, Finance, and Electronics Sectors

Cybersecurity researchers have uncovered a new espionage campaign targeting media, construction, engineering, electronics, and finance sectors in Japan, Taiwan, the U.S. and China. Linking the attacks to Palmerworm (aka BlackTech), likely a China-based advanced persistent threat (APT), the first wave of activity associated with this campaign began last year in August 2019.

InterPlanetary Storm Botnet Infects 13K Mac, Android Devices

A new variant of the InterPlanetary Storm malware has been discovered, which comes with fresh detection-evasion tactics and now targets Mac and Android devices (in addition to Windows and Linux, which were targeted by previous variants of the malware). Researchers say the malware is building a botnet with a current estimated 13,500 infected machines across 84 countries worldwide – and that number continues to grow.

More Americans Share Social Security, Financial and Medical Information than Before the Pandemic

A new survey has shown that consumer willingness to share more sensitive data – social security numbers, financial information and medical information – is greater in 2020 than in both 2018 and 2019. According to the NYC-based scientific research foundation ARF’s (Advertising Research Foundation) third annual privacy study, contact tracing is considered a key weapon in the fight against COVID-19.

Do you feel like you are more willing to share sensitive information online since the pandemic began? Share your thoughts in the comments below or follow me on Twitter to continue the conversation: @JonLClay.

IOC's turning into IOOI's, (Thu, Oct 1st)

Remember, back in the days, when the anti-virus vendors looked with derision at some of their competition, exclaiming "But they are using just SIGNATURES. Our tool detects BEHAVIOURS".  That was like 15 years ago. Fast forward to today, with many of the same vendors now selling "threat intelligence feeds" for good money, and the most frequent attributes pushed over these feeds are MD5/SHA1 hashes and IP addresses. The main thing that changed is that we now call these items "IOCs" (Indicators of Compromise) instead of "signatures", but they still mostly are what they always were: Binary fingerprints that are very easy for an attacker to change.

Identity Fraud: How to Protect Your Identity Data, Accounts and Money During the Coronavirus Crisis

By Trend Micro

We’ve all been spending more of our time online since the crisis hit. Whether it’s ordering food for delivery, livestreaming concerts, holding virtual parties, or engaging in a little retail therapy, the digital interactions of many Americans are on the rise. This means we’re also sharing more of our personal and financial information online, with each other and the organizations we interact with. Unfortunately, as ever, there are bad guys around every digital corner looking for a piece of the action.

The bottom line is that personally identifiable information (PII) is the currency of internet crime. And cyber-criminals will do whatever they can to get their hands on it. When they commit identity theft with this data, it can be a messy business, potentially taking months for banks and businesses to investigate before you get your money and credit rating back. At a time of extreme financial hardship, this is the last thing anyone needs.

It therefore pays to be careful about how you use your data and how you protect it. Even more: it’s time to get proactive and monitor it—to try and spot early on if it has been stolen. Here’s what you need to know to protect your identity data.

How identity theft works

First, some data on the scope of the problem. In the second quarter of 2020 alone 349,641 identity theft reports were filed with the FTC. To put that in perspective, it’s over half of the number for the whole of 2019 (650,572), when consumers reported losing more than $1.9 billion to fraud. What’s driving this huge industry? A cybercrime economy estimated to be worth as much as $1.5 trillion annually.

Specialized online marketplaces and private forums provide a user-friendly way for cyber-criminals and fraudsters to easily buy and sell stolen identity data. Many are on the so-called dark web, which is hidden from search engines and requires a specialized anonymizing browser like Tor to access. However, plenty of this criminal activity also happens in plain sight, on social media sites and messaging platforms. This underground industry is an unstoppable force: as avenues are closed down by law enforcement or criminal in-fighting, other ones appear.

At-risk personal data could be anything from email and account log-ins to medical info, SSNs, card and bank details, insurance details and much more. It all has a value on the cybercrime underground and the price fraudsters are prepared to pay will depend on supply and demand, just like in the ‘real’ world.

There are various ways for attackers to get your data. The main ones are:

  • Phishing: usually aimed at stealing your log-ins or tricking you into downloading keylogging or other info-stealing malware. Phishing mainly happens via email but could also occur via web, text, or phone. Around $667m was lost in imposter scams last year, according to the FTC.
  • Malicious mobile apps disguised as legitimate software.
  • Eavesdropping on social media: If you overshare even innocuous personal data (pet names, birth dates, etc.,) it could be used by fraudsters to access your accounts.
  • Public Wi-Fi eavesdropping: If you’re using it, the bad guys may be too.
  • Dumpster diving and shoulder surfing: Sometimes the old ways are still popular.
  • Stealing devices or finding lost/misplaced devices in public places.
  • Attacking the organizations you interact with: Unfortunately this is out of your control somewhat, but it’s no less serious. There were 1,473 reported corporate breaches in 2019, up 17% year-on-year.
  • Harvesting card details covertly from the sites you shop with. Incidents involving this kind of “web skimming” increased 26% in March as more users flocked to e-commerce sites during lockdown.

 

The COVID-19 challenge

As if this weren’t enough, consumers are especially exposed to risk during the current pandemic. Hackers are using the COVID-19 threat as a lure to infect your PC or steal identity data via the phishing tactics described above. They often impersonate trustworthy institutions/officials and emails may claim to include new information on outbreaks, or vaccines. Clicking through or divulging your personal info will land you in trouble. Other fraud attempts will try to sell counterfeit or non-existent medical or other products to help combat infection, harvesting your card details in the process. In March, Interpol seized 34,000 counterfeit COVID goods like surgical masks and $14m worth of potentially dangerous pharmaceuticals.

Phone-based attacks are also on the rise, especially those impersonating government officials. The aim here is to steal your identity data and apply for government emergency stimulus funds in your name. Of the 349,641 identity theft reports filed with the FTC in Q2 2020, 77,684 were specific to government documents or benefits fraud.

What do cybercriminals do with my identity data?

Once your PII is stolen, it’s typically sold on the dark web to those who use it for malicious purposes. It could be used to:

  • Crack open other accounts that share the same log-ins (via credential stuffing). There were 30 billion such attempts in 2018.
  • Log-in to your online bank accounts to drain it of funds.
  • Open bank accounts/credit lines in your name (this can affect your credit rating).
  • Order phones in your name or port your SIM to a new device (this impacts 7,000 Verizon customers per month).
  • Purchase expensive items in your name, such as a new watch or television, for criminal resale. This is often done by hijacking your online accounts with e-tailers. E-commerce fraud is said to be worth around $12 billion per year.
  • File fraudulent tax returns to collect refunds on your behalf.
  • Claim medical care using your insurance details.
  • Potentially crack work accounts to attack your employer.

How do I protect my identity online?

The good news among all this bad is that if you remain skeptical about what you see online, are cautious about what you share, and follow some other simple rules, you’ll stand a greater chance of keeping your PII under lock and key. Best practices include:

  • Using strong, long and unique passwords for all accounts, managed with a password manager.
  • Enable two-factor authentication (2FA) if possible on all accounts.
  • Don’t overshare on social media.
  • Freeze credit immediately if you suspect data has been misused.
  • Remember that if something looks too good to be true online it usually is.
  • Don’t use public Wi-Fi when out-and-about, especially not for sensitive log-ins, without a VPN.
  • Change your password immediately if a provider tells you your data may have been breached.
  • Only visit/enter payment details into HTTPS sites.
  • Don’t click on links or open attachments in unsolicited emails.
  • Only download apps from official app stores.
  • Invest in AV from a reputable vendor for all your desktop and mobile devices.
  • Ensure all operating systems and applications are on the latest version (i.e., patch frequently).
  • Keep an eye on your bank account/credit card for any unusual spending activity.
  • Consider investing in a service to monitor the dark web for your personal data.

How Trend Micro can help

Trend Micro offers solutions that can help to protect your digital identity.

Trend Micro ID Security is the best way to get proactive about data protection. It works 24/7 to monitor dark web sites for your PII and will sound the alarm immediately if it finds any sign your accounts or personal data have been stolen. It features

  • Dark Web Personal Data Manager to scour underground sites and alert if it finds personal info like bank account numbers, driver’s license numbers, SSNs and passport information.
  • Credit Card Checker will do the same as the above but for your credit card information.
  • Email Checker will alert you if any email accounts have been compromised and end up for sale on the dark web, allowing you to immediately change the password.
  • Password Checker will tell you if any passwords you’re using have appeared for sale on the dark web, enabling you to improve password security.

Trend Micro Password Manager enables you to manage all your website and app log-ins from one secure location. Because Password Manager remembers and recalls your credentials on-demand, you can create long, strong and unique passwords for each account. As you’re not sharing easy-to-remember passwords across multiple accounts, you’ll be protected from popular credential stuffing and similar attacks.

Finally, Trend Micro WiFi Protection will protect you if you’re out and about connecting to WiFi hotspots. It automatically detects when a WiFi connection isn’t secure and enables a VPN—making your connection safer and helping keep your identity data private.

In short, it’s time to take an active part in protecting your personal identity data—as if your digital life depended on it. In large part, it does.

IoT Security Fundamentals: Intercepting and Manipulating Wireless Communications

By Dimitar Kostadinov

Introduction: IoT Manufacturers Favor Convenience over Security Because IoT security is still an afterthought, cybercriminals in general consider smart devices a “low-hanging fruit” – a target easy to compromise and manipulate. Security (and privacy) by design is key for IoT, and probably the only effective way for a smart gadget to protect its communications is […]

PowerShell Backdoor Launched from a ShellCode, (Mon, Sep 28th)

When you need to perform malicious actions on a victim's computer, the Internet is full of resources that can be reused, forked, slightly changed to meet your requirements. After all, why reinvent the wheel if some pieces of code are available on GitHub for free? If you developed some offensive tools for good reasons (because you're a pentester, a red teamer of just doing some research), chances are high that your code will be reused.

This Week in Security News: Cybercriminals Distribute Backdoor with VPN Installer and New ‘Alien’ Malware can Steal Passwords from 226 Android Apps

By Jon Clay (Global Threat Communications)

 

Welcome to our weekly roundup, where we share what you need to know about the cybersecurity news and events that happened over the past few days. This week, learn about how threat actors are bundling Windscribe VPN installers with backdoors. Also, read about a new strain of Android malware that comes with a wide array of features allowing it to steal credentials from 226 applications.

 

 

Read on:

 

Windows Backdoor Masquerading as VPN App Installer

This article discusses findings covered in a recent blog from Trend Micro where company researchers warn that Windows users looking to install a VPN app are in danger of downloading one that’s been bundled with a backdoor. The trojanized package in this specific case is the Windows installer for Windscribe VPN and contains the Bladabindi backdoor.

The Evolution of Malicious Shell Scripts

The Unix-programming community commonly uses shell scripts as a simple way to execute multiple Linux commands within a single file. Many users do this as part of a regular operational workload manipulating files, executing programs and printing text. However, as a shell interpreter is available in every Unix machine, it is also an interesting and dynamic tool abused by malicious actors.

Microsoft Says It Detected Active Attacks Leveraging Zerologon Vulnerability

Hackers are actively exploiting the Zerologon vulnerability in real-world attacks, Microsoft’s security intelligence team said on Thursday morning. The attacks were expected to happen, according to security industry experts. Multiple versions of weaponized proof-of-concept exploit code have been published online in freely downloadable form since details about the Zerologon vulnerability were revealed on September 14 by Dutch security firm Secura BV.

Stretched and Stressed: Best Practices for Protecting Security Workers’ Mental Health

Security work is stressful under the best of circumstances, but remote work presents its own challenges. In this article, learn how savvy security leaders can best support their teams today — wherever they’re working. Trend Micro’s senior director of HR for the Americas, Bob Kedrosky, weighs in on how Trend Micro is supporting its remote workers.

Exploitable Flaws Found in Facial Recognition Devices

To gain a more nuanced understanding of the security issues present in facial recognition devices, Trend Micro analyzed the security of four different models: ZKTeco FaceDepot-7B, Hikvision DS-K1T606MF, Telpo TPS980 and Megvii Koala. Trend Micro’s case studies show how these devices can be misused by malicious attackers.

New ‘Alien’ Malware Can Steal Passwords from 226 Android Apps

Security researchers have discovered and analyzed a new strain of Android malware that comes with a wide array of features allowing it to steal credentials from 226 applications. Named Alien, this new trojan has been active since the start of the year and has been offered as a Malware-as-a-Service (MaaS) offering on underground hacking forums.

Government Software Provider Tyler Technologies Hit by Possible Ransomware Attack

Tyler Technologies, a Texas-based provider of software and services for the U.S. government, started informing customers this week of a security incident that is believed to have involved a piece of ransomware. Tyler’s website is currently unavailable and in emails sent out to customers the company said its internal phone and IT systems were accessed without authorization by an “unknown third party.”

U.S. Justice Department Charges APT41 Hackers Over Global Cyberattacks

On September 16, 2020, the United States Justice Department announced that it was charging five Chinese citizens with hacking crimes committed against over 100 institutions in the United States and abroad. The global hacking campaign went after a diverse range of targets, from video game companies and telecommunications enterprises to universities and non-profit organizations. The five individuals were reportedly connected to the hacking group known as APT41.

Phishers are Targeting Employees with Fake GDPR Compliance Reminders

Phishers are using a bogus GDPR compliance reminder to trick recipients – employees of businesses across several industry verticals – into handing over their email login credentials. In this evolving campaign, the attackers targeted mostly email addresses they could glean from company websites and, to a lesser extent, emails of people who are high in the organization’s hierarchy.

Mispadu Banking Trojan Resurfaces

Recent spam campaigns leading to the URSA/Mispadu banking trojan have been uncovered, as reported by malware analyst Pedro Tavares in a Twitter post and by Seguranca Informatica in a blog post. Mispadu malware steals credentials from users’ systems. This attack targets systems with Spanish and Portuguese as system languages.

A Blind Spot in ICS Security: The Protocol Gateway Part 3: What ICS Security Administrators Can Do

In this blog series, Trend Micro analyzes the impacts of the serious vulnerabilities detected in the protocol gateways that are essential when shifting to smart factories and discusses the security countermeasures that security administrators in those factories must take. In the final part of this series, Trend Micro describes a stealth attack method that abuses a vulnerability as well as informs readers of a vital point of security measures required for the future ICS environment.

Major Instagram App Bug Could’ve Given Hackers Remote Access to Your Phone

Check Point researchers disclosed details about a critical vulnerability in Instagram’s Android app that could have allowed remote attackers to take control over a targeted device just by sending victims a specially crafted image. The flaw lets attackers perform actions on behalf of the user within the Instagram app, including spying on victim’s private messages and deleting or posting photos from their accounts, as well as execute arbitrary code on the device.

Addressing Threats Like Ryuk via Trend Micro XDR

Ryuk has recently been one of the most noteworthy ransomware families and is perhaps the best representation of the new paradigm in ransomware attacks where malicious actors go for quality over sheer quantity. In 2019, the Trend Micro™ Managed XDR and Incident Response teams investigated an incident concerning a Trend Micro customer that was infected with the Ryuk ransomware.

Party in Ibiza with PowerShell, (Thu, Sep 24th)

Today, I would like to talk about PowerShell ISE or "Integration Scripting Environment"[1]. This tool is installed by default on all Windows computers (besides the classic PowerShell interpreter). From a malware analysis point of view, ISE offers a key feature: an interactive debugger! It provides all the classic features that you can expect from a debugger: breakpoints, step in, step over, step out, ... all of these features are available while you keep control of the environment to interact with the script through the help of other PowerShell commands. When you're facing a strongly obfuscated scripts, you could speed up the analysis with the help of carefully placed breakpoints. Let's have a look at a practical example.

Malicious Word Document with Dynamic Content, (Wed, Sep 23rd)

Here is another malicious Word document that I spotted while hunting. "Another one?" may ask some of our readers. Indeed but malicious documents remain a very common infection vector and you learn a lot when you analyze them. I was recently asked to talk about Powershell (de)obfuscation techniques. When you're dealing with an incident in a corporate environment, you don't have time to investigate in deep. The incident must be resolved as soon as possible because the business must go on and a classic sandbox analysis is performed to get the feedback: It's malicious or not.
