In yet another example of how threat actors are abusing Google Ads to deliver malware, threat actors can use this technique to steal information called a new Windows-based financial Trojan and information-stealing program. Confirmed. lob shot.

Elastic Security Labs researcher Daniel Stepanic said in an analysis published last week, “LOBSHOT continues to collect victims while remaining under the radar.

“One of LOBSHOT’s core features concerns its hVNC (Hidden Virtual Network Computing) component. These kinds of modules allow direct and unsupervised access to the machine.”

The American-Dutch company attributed this malware strain to a threat actor known as TA505 based on the infrastructure historically connected to this group. TA505 is a financially motivated electronic crime syndicate that overlaps with activity clusters tracked under the names Evil Corp, FIN11, and Indrik Spider.

The latest development is significant as it is a sign that TA505, associated with the Dridex banking Trojan, is once again expanding its malware arsenal to carry out data theft and financial fraud.

With early samples dating back to July 2022, LOBSHOT is distributed by deceptive Google ads for legitimate tools like AnyDesk hosted on a network of similar operator-controlled landing pages.

The malware incorporates dynamic import resolution (resolving the names of required Windows APIs at runtime), anti-emulation checks, and string obfuscation to avoid detection by security software.

Once installed, it modifies the Windows registry to set persistence and siphon data from over 50 cryptocurrency wallet extensions present in web browsers such as Google Chrome, Microsoft Edge, and Mozilla Firefox.

Other notable features of LOBSHOT revolve around its ability to remotely access a compromised host via its hVNC module and perform actions covertly without attracting the victim’s attention.

“Threat groups continue to leverage malvertising techniques to disguise legitimate software with backdoors like LOBSHOT,” said Stepanic.

“Although this type of malware may seem small, it packs important features that help attackers act quickly in the early stages of access, with fully interactive remote control capabilities.”
