The GlassWorm malware has reared its ugly head once more within the Open VSX registry, roughly two weeks after being faraway from the Visible Studio (VS) Code extensions market, Koi Safety experiences.
In mid-October, the malware landed within the registry by means of a set of almost a dozen contaminated extensions, aiming to steal NPM, GitHub, and Git credentials, together with different delicate info and funds from 49 cryptocurrency extensions.
Koi Safety estimated on the time that the malware was downloaded roughly 35,000 occasions, warning that it might propagate by infecting the extensions and packages discovered on victims’ techniques.
What made the malware stand out was its use of Unicode variation selectors to cover its code in editors and using the Solana blockchain for command-and-control (C&C) infrastructure. It additionally supplied distant entry to the contaminated machines, by deploying SOCKS proxy servers and hidden VNC servers.
Open VSX stated in late October that the assault had been contained inside days and that extra safety measures had been carried out to stop comparable assaults.
Declaring that GlassWorm was not a self-propagating worm, Open VSX stated all contaminated extensions had been faraway from the registry, and that the incident was thought-about contained as of October 21.
Now, Koi warns that three extra contaminated VS Code extensions had been found within the registry on November 6, with a mixed obtain rely of roughly 10,000.
The attackers pushed a brand new Solana blockchain transaction to feed new C&C addresses to the malware, to obtain a next-stage payload. The exfiltration server, nevertheless, remained unchanged from the primary wave of assaults.Commercial. Scroll to proceed studying.
Koi additionally says it gained entry to the attackers’ server and peeked on the stolen knowledge, which included a partial record of GlassWorm’s victims. The record contains dozens of builders and organizations, together with entities within the US, Europe, Asia, and Latin America, in addition to a authorities entity within the Center East.
The attackers, Koi notes, stole the victims’ credentials and are probably abusing their computer systems as prison proxy infrastructure.
Keylogger knowledge found on the server revealed that the risk actor is Russian-speaking, that they use the open supply browser extension C&C framework RedExt as a part of their infrastructure, and that they use a number of cryptocurrency exchanges and messaging platforms.
“We’re presently working with legislation enforcement companies to inform affected victims and coordinate efforts to take down the attacker’s infrastructure. However the actuality is sobering: this marketing campaign has been operating for over a month, and it continues to unfold,” Koi says.
Extra worrying is that malicious code like GlassWorm’s, additionally hidden from code editors utilizing Unicode characters, was discovered on GitHub. Aikido Safety, which found a number of repositories containing the malicious script, notes that the identical risk actor is probably going behind each the Open VSX and GitHub assaults.
“Attackers are mixing malicious code with life like commits and project-specific enhancements, presumably aided by AI to make their adjustments seem pure. It’s a signal of the place the risk panorama is heading,” Aikido says.
