Cyberattacks are now being reported at an incredible rate, with many of those attacks having devastating consequences for small- and medium-sized businesses. According to Cybersecurity Ventures, around 60% of small- to medium-sized companies go out of business within 6 months of suffering a data breach. Cyberattacks are becoming much more sophisticated, but oftentimes these incredibly damaging attacks are not conducted by highly skilled hackers. The bar for conducting these attacks can be incredibly low, which means anyone with a modicum of skill can conduct attacks and profit. One of the ways that would-be hackers can start conducting attacks is by taking advantage of the many ransomware-as-a-service and malware-as-a-service offerings on hacking forums and darknet marketplaces. Take Redline malware for example.

Redline malware is a commodity information stealer that is easily obtained on hacking and cybercrime forums. The malware costs between $100-$200, and payment can be made anonymously using cryptocurrencies. At such a low price it is available to virtually anyone, and conducting attacks requires little effort or skill.

The Redline stealer was first identified in March 2020 and soon became one of the most prevalent malware threats with the number of attacks continuing to grow. Redline malware has been used in attacks on a wide range of businesses, with the manufacturing and healthcare sectors two of the most commonly attacked sectors.

Redline malware has been updated several times since it first emerged, with new features added such as the ability to exfiltrate credentials, steal cryptocurrency wallets, FTP authentication data, passwords stored in browsers, and gather information about the infected system. It is also capable of loading remote payloads and uses a SOAP API for C2 communication. One successful attack could see the attacker recover the purchase cost many times over.

Like many other malware variants, the most common method of delivery is email. Emails are broadcast using huge mailing lists, which can also be purchased at a low cost on cybercrime forums.  Alternatively, more targeted campaigns can be conducted on specific businesses, with the emails often having a much higher chance of success due to the personalization of the emails.

The emails usually contain a malicious hyperlink and use social engineering techniques to trick employees into clicking. When the link is clicked, the binary file is downloaded and installed on the user’s device. While antivirus software should identify and block the malware threat, there have been many cases where AV engines have failed to detect the malware.

Redline malware will obtain a list of processes running on an infected device, including the security solutions in place. Attackers can interact with the malware remotely and view information about the infected system, can create and download remote files, silently run commands on an infected machine, and steal highly sensitive information. One of the biggest threats is the ability to steal data from browsers, including passwords stored in the Chrome, Edge, and opera browsers.  Most browsers encrypt stored passwords, but Redline malware can programmatically decrypt the password store in Chromium-based browsers, provided they are logged in as the same user. Redline malware runs as the user that infected the device and can steal that user’s passwords from their password file.

Not everyone stores their passwords in their browser, but there is still a threat. When the browser suggests storing a password and the request is refused, a record is kept about that refusal so a further request will not be suggested next time the user visits that particular website. That record can be stolen from the browser, so the attacker will discover what accounts the user has and can then conduct phishing campaigns to obtain the passwords or use credential stuffing attacks. Much of the data stolen in redline malware attacks can easily be monetized on cybercrime forums.

Malware-as-a-service has opened up cyberattacks to a much broader range of individuals, but ultimately the attacks depend on employees being tricked into clicking links in emails or opening infected email attachments. Blocking those emails is the best approach to blocking the malware threats, which is where SpamTitan is invaluable.

SpamTitan Plus includes 100% of all current market-leading anti-phishing feeds. That translates into a 1.5x increase in phishing URL detections and 1.6x faster phishing detections than the current market leaders. 10 million net new, previously undiscovered phishing URLs are identified every day, and it takes just 5 minutes from a phishing URL being detected to all end users’ inboxes being protected. Time-of-click verification of links in emails involves multiple dynamic checks of redirects and there are dual anti-virus engines and a Bitdefender-powered sandbox to identify any malicious files attached to emails.

If you want to protect against malware and phishing attacks and ensure your company does not suffer an incredibly damaging cyberattack and data breach, give the TitanHQ team a call for more information on SpamTitan.
