Thanks to the presence of a previously unknown Windows backdoor, the MadMXShell malware has created digital chaos through the use of Google Ads

Google Ads are a common sight for anyone stepping foot online, and they’re a sure-fire way to guarantee clicks for those behind the advertising campaigns. Naturally, this makes of great interest to threat actors, as not only is malvertising a useful tool for hacking, but it’s also an easy way to lead people to malicious websites. MadMXShell appears to be a complex piece of malware, comprising several attack methods and tools, so it’s crucial that your organization is on guard against it.

How MadMXShell Serves Up its Malware

The threat actor responsible for MadMXShell is yet to be identified, but the effort invested in the attack demonstrates they’re highly skilled. Having created several domains in the IP scanner niche – with similar sounding names to official sites (a technique known as typosquatting) – the threat actor took advantage of the Google Ads algorithm to push them to the top of the search engine results. This was achieved by targeting keywords – words/phrases entered into search engines by those searching for specific content – and ensuring that their click rate was maximized.

Once lured to these malicious websites, it appears that visitors are encouraged to download IP scanner software. But, as you’ve already worked out, there is no IP scanner software to download. Instead, MadMXShell is downloaded and executed. With its strategy made up of a multi-targeted attack, MadMXShell sets to work harvesting data from infected systems. It does this by communicating with command-and-control servers and evades detection by injecting altered code into seemingly legitimate processes.

Curiously, as the entire campaign centers around IP scanning software, it would appear the main target of MadMxShell are IT professionals. Despite being a tough crowd to deceive, MadMXShell has already managed to gain plenty of victims, and underlines the ease with which even professionals can be taken in by malware.

Keeping the Threat of MadMxShell at Bay

It may sound as though MadMxShell is impossible to protect yourself against, especially if IT experts are struggling to defend against its threat. However, by taking the time to consider the validity of content you see online, you can significantly reduce the risk of falling victim to MadMxShell or similar attacks. The most important factors to consider are:

  • Always Verify Sources: before clicking on an online advert, always verify its source. If you’re unfamiliar with a website name then try performing a Google search against it, as this may flag it up as a malicious website. Remember, many attacks will use typosquatting, so it’s important that URLs are double checked e.g. usa.visa.com is official, but usa.v1sa.com is an attempt to fake the official website.
  • If It’s Too Good to Be True: online adverts which are offering unlikely and unrealistic rewards should always be scrutinized closely. While they may not necessarily link you to malicious websites, it’s more than likely that some form of scam/deception is the most likely end point.
  • Use an Adblocker: pop-up adverts are both annoying and a potential security risk, so why not minimize these risks by installing an adblocker into your browser? Easy to operate, and available for free, these browser add-ons allow you to prevent pop-up adverts from being displayed on your screen. Popular adblockers include Adblock Plus, Privacy Badger, and Ghostery.

As a business owner, it’s crucial you protect the data held by your organization. And the FTC Safeguards Rule means this is an absolute necessity.

Originating as part of the Gramm-Leach-Bliley Act in 2002, the FTC Safeguards Rule is a set of regulations which govern how a business must protect its data. After all, a business not only holds sensitive information regarding its customers, but also its employees. And in the modern age, this data is constantly in the crosshairs of threat actors. Therefore, safeguarding this data is paramount. Otherwise, your business is at risk of being slapped with hefty fines and penalties.

A Closer Look at the FTC Safeguards Rule

If you want to adhere to the FTC Safeguards Rule, you need to put a comprehensive strategy into place. Our recommendations for drawing up a plan are:

What Happens When You Don’t Comply?

As of June 2023, if your business fails to comply with the FTC Safeguards Rule, the FTC have the power to hit you with a fine of up to $100,000 per violation. And if you make multiple violations, these fines can quickly cause you major financial damage. There’s also the risk of any affected customers or employees also taking legal action against you. Compliance with the FTC Safeguards Rule, therefore, needs to be a major priority for businesses of any size.

The Best Ways to Secure Your Digital Documents

Every business relies on digital documents, but the threat of data breaches and cyberattacks mean these documents must be correctly secured.

There are many types of documents a business uses daily such as Word, Excel, PDF, and digital images. All of these can contain sensitive information, and it’s no surprise threat actors want to get their hands on them. Not only can a threat actor use these to compromise other accounts, but they can cause real financial damage with them. Accordingly, it makes sense to secure your organization’s digital documents to keep them safe.

Securing Your Digital Documents

Your business may contain numerous files in different locations, but the good news is that securing all of them is straightforward. Just make sure you follow these best practices:

  • Password Protection: the simplest way to secure your digital documents is by implementing password protection. A common security measure for decades, passwords put a major barrier in the way of unauthorized access. Not all files can be password protected, but common files such as Microsoft 365 documents and Adobe PDF documents can.
  • Use Strong Passwords: central to good password protection is strong passwords. Never use passwords which are easy to guess e.g. using “password” or “admin”. Instead, always use passwords which combine upper and lower case characters with numbers and symbols. It’s also recommended that passwords are longer than 8 characters and different passwords should be used for different documents.
  • Restrict Access: it’s important to remember not every employee needs access to every single file within your organization. Your marketing team, for example, doesn’t need access to your finance team’s documents and vice-versa. Accordingly, you need to restrict access to only those who need it. The best way to achieve this is by setting up ‘restricted’ drives for each team to store their department-specific documents.
  • Use Windows Encryption: compromised devices present a goldmine of data for threat actors, but it’s possible to avoid this disaster by encrypting your devices. Yes, if you’re running Windows 10/11 Pro or Enterprise versions, it’s possible to encrypt data and provide access only to those with authorization. This is easy to put in place and, if Windows encryption is not available on the device, you may still be able to use BitLocker encryption to encrypt it.
  • Always Create Backups: in the event of a ransomware attack, your organization could find all of its documents encrypted and inaccessible. This is why creating backups is the surest way to enhance the security of your digital documents. The preferred method for executing this is with the 3-2-1 backup method, as this provides you with multiple copies in different locations. Complete loss of your data is minimized and there’s no need to pay any ransom fees.

Final Thoughts

All it takes is for a single file to be compromised by threat actors to cause major damage, so it’s crucial that you prioritize securing your digital documents. Putting the suggestions above into practice is relatively easy, and it ensures your data remains safe. So, don’t delay, secure your digital documents today and benefit from the peace of mind it provides.

Financial Firms Targeted by JsOutProx Malware

May 2024

A new phishing campaign, launched in March 2024, has been targeting financial firms all over the world with the JsOutProx banking trojan.

The JsOutProx malware campaign was first detected by Visa, with their Payment Fraud Disruption team sending out security alerts to stakeholders about the threat. So far, the targets of the attack have been based in Africa, South Asia, and the Middle East. The identity of the threat actors behind the attack are currently unknown, but it’s speculated they may be China-based or receiving support from China.

Financial malware always has the potential to cause great damage to organizations and individuals, so it’s important you understand the threat posed by JsOutProx.

The Lowdown on JsOutProx

First detected online in 2019, JsOutProx provides remote access to infected PCs by way of a JavaScript backdoor. This foothold allows threat actors to carry out numerous malicious attacks within the infected system. These include downloading further malware, data harvesting, taking screenshots, executing files, and embedding itself deep within the target. Plugins are utilized to launch these attack methods, an indicator this is a sophisticated piece of malware.

JsOutProx relies on JavaScript to carry out its attacks, and this method has been employed to deceive targets. Whereas many PC users understand the threat of a specific file type – such as a Word document or .exe file – they’re less likely to have knowledge of the threat posed by JavaScript code. Additionally, JavaScript coding is unintelligible to many anti-malware tools, so it has the potential to go undetected by software expected to keep PCs secure.

How is the JsOutProx Attack Launched?

Using phishing email techniques, JsOutProx is distributed through emails purporting to be related to MoneyGram or SWIFT payment notifications. However, far from being from genuine financial institutions, the senders behind these emails only have malicious intentions. Once recipients have fallen for the bait in the phishing emails, the JsOutProx code is activated and allows the threat actors to position themselves within the infected PC. Once installed, JsOutProx adopts a number of functionalities to enhance its position, such as changing DNS settings, editing proxy settings, and bypassing User Account Control detection.

Protect Your PCs from JsOutProx

A significant proportion of internet users have access to online banking services, and this is why JsOutProx has maximized its chances of snaring victims. Thankfully, you don’t have to fall victim to JsOutProx and compromise the security of your PC. All you have to do is make sure you practice the following:

  • Protect your browsers from scripts: many malware attacks such as JsOutProx rely on scripts to launch their attack within browsers. Therefore, it makes sense to protect your browsers from malicious scripts. Luckily, this is a relatively simple task thanks to ready-made browser plugins such as ScriptSafe for Chrome. These browser extensions protect you by blocking unwanted content and providing alerts against blacklisted sites which are malicious.
