A new, financially motivated operation dubbed LABRAT has been observed weaponizing a now-patched critical flaw in GitLab as part of a cryptojacking and proxyjacking campaign.

Proxyjacking allows the attacker to rent the compromised host out to a proxy network, making it possible to monetize the unused bandwidth. Cryptojacking, on the other hand, refers to the abuse of the system resources to mine cryptocurrency. A notable aspect of the campaign is the use of compiled binaries written in Go and .NET to fly under the radar, with LABRAT also providing backdoor access to the infected ...
