RedLine Stealer Identified as Major Source of Stolen Credentials on Dark Web Markets

 

A significant proportion of stolen credentials being traded on two dark web underground marketplaces were gathered via the RedLine Stealer malware, according to Insikt Group, Recorded Future's cybersecurity research arm. 

The RedLine Stealer, first discovered in March 2020, is a part of the info stealer family, a form of malware that once infects a computer and its primary goal is to capture as much user data as possible and then deliver it to the attackers, who often sell it online. 

The RedLine Stealer has data gathering features such as the ability to extract login credentials from web browsers, FTP applications, email apps, instant messaging clients, and VPNs. RedLine can also harvest authentication cookies and card numbers from browsers, chat logs, local files, and cryptocurrency wallet databases. 

Since March 2020, the malware has been sold on many underground hacking sites by a coder called REDGlade. After good feedback in a hacking forum thread, unauthorized versions of the RedLine Stealer were distributed on hacker forums a few months later, in August of this year, facilitating it to proliferate to even more threat actors who did not have to pay for it. 

But, even before the cracked version was released, RedLine had gained a devoted following. According to a report published last week by Insikt Group, the majority of stolen credentials available for sale on two underground marketplaces originate from computers infected with the RedLine Stealer. 

Insikt researchers stated, “Both Amigos Market and Russian Market were identified by Insikt Group (June 2021) posting identical listings regularly that contained the same timestamps, infostealer variants used, geographical locations of affected machines, and ISPs.” 

The results of the Insikt team follow similar research by threat intelligence firm KELA from February 2020, which discovered that around 90% of stolen credentials sold on the Genesis Market originated from infections with the AZORult infostealer. 

According to the two reports, underground cybercrime marketplaces are fragmented and often operate with their own independent suppliers, just as legal markets have their own choices for particular business partners. 

By going after the producers and dealers of these infostealers, this fragmentation opens the path to impairing the supply of multiple underground markets. In February 2020, a Chrome upgrade (which modified how credentials were saved inside the browser) halted the flow of newly stolen credentials on Genesis Market for months until the AZORult stealer was modified to assist the new format.

Dark web listings for malware aimed at companies on rise


There's been a significant rise in the number of dark web listings for malware and other hacking tools which target the enterprise, and an increasing number of underground vendors are touting tools that are designed to target particular industries.

A study by cybersecurity company Bromium and criminologists at the University of Surrey involved researchers studying underground forums and interacting with cyber-criminal vendors. The study found that the dark web is fast becoming a significant source of bespoke malware.

In many cases, the dark web sellers demonstrated intimate knowledge of email systems, networks and even cybersecurity protocols in a way that suggests they themselves have spent a lot of time inside enterprise networks, raising questions about security for some companies.

"What surprised me is the extent you could obtain malware targeting enterprise, you could obtain operational data relating to enterprise," Mike McGuire, senior lecturer in Criminology at the University of Surrey and author of the study, told ZDNet.

"There seems to be an awareness and sophistication among these cyber criminals, to go for the big fry, to go where the money is, as a criminal, and the enterprise is providing that," he said, adding: "What surprised me is just how easy it is to get hold of it if you want to."

McGuire and his team interacted with around 30 sellers on dark web marketplaces – sometimes on forums, sometimes via encrypted channels, sometimes by email – and the findings have been detailed in the Behind the Dark Net Black Mirror report.

The study calculated that since 2016, there's been a 20 percent rise in the number of dark web listings that have the potential to harm the enterprise.

Malware and distributed denial of service (DDoS) form almost half of the attacks on offer – a quarter of the listings examined advertised malware and one in five offered DDoS and botnet services. Other common services targeting enterprises that were for sale include espionage tools, such as remote-access Trojans and keyloggers.
