Threat Database Malware LabRat Malware

LabRat Malware

An insidious malware package that is exceptionally difficult to detect has triggered concerns due to its apparent capability to bypass numerous defensive measures and security protocols. In-depth research conducted by experts has unveiled the LabRat malware, which exhibits a remarkable level of sophistication in its strategies to remain hidden and operational without being detected.

Unlike the majority of similar cyber attacks that prioritize speed over subtlety, the deployment of the LabRat malware demonstrates a high degree of sophistication. This threat actor has meticulously designed their operation with particular attention to stealth, a factor that many attackers tend to neglect. These conscientious efforts on the part of the threat actor are poised to significantly heighten the challenges faced by defenders in identifying and countering this threat.

The LabRat Malware Carries out Crypto and Proxyjacking Actions

Analysis of the LabRat malware shows the threat to be a relatively typical instance of a cryptojacking and proxy jacking tool. In a cryptojacking campaign, the attackers utilize the victim's computer covertly to mine cryptocurrency, generating profits by exploiting the resources of the victim. On the other hand, a proxy-jacking campaign involves quietly enlisting the victim's computer into a peer-to-peer bandwidth-sharing network, which benefits the attacker by expanding their resources.

The method of attack relies on a recognized vulnerability within GitLab servers (CVE-2021-2205), exploiting it to achieve remote code execution and introduce the malware payload onto the compromised machine.

What distinguishes this particular attack campaign, however, is the notable dedication exhibited by the malware creators in concealing their code. Furthermore, the adoption of the TryCloudFlare service to route the traffic adds an extra layer, effectively masking the attackers' identities from the systems they have compromised.

The LabRat Attack Operation Shows Significant Focus on Stealth

The LabRat malware is fortified with robust encryption and sophisticated anti-reverse engineering techniques, rendering its detection an exceedingly challenging task. The persistence binaries, coded in Go, exhibited a remarkable ability to remain unnoticed, as did the crypto-miner components employed by the attack.

Researchers observed that the LabRat group had exhibited an exceptional level of commitment in their endeavors to obscure the code, allowing the threatening payload to operate covertly. Indeed, the threat actors behind this campaign appear to place a greater emphasis on maintaining stealth compared to many others, as they recognize that time directly corresponds to increased financial gain. The longer they can sustain their access while running the proxy jacking and cryptomining software, the greater their monetary returns.

The importance of remaining unnoticed is particularly significant in the context of proxy jacking, where the effectiveness of an unattributable network is directly linked to the number of nodes within it. Should the node count dwindle, the service becomes vulnerable to being blocked or simply becoming ineffective.
