A malicious VS Code extension has surfaced within the digital risk panorama, concentrating on builders who depend on coding instruments day by day.
Found on January 27, 2026, the pretend “ClawdBot Agent” extension introduced itself as a official AI-powered assistant, but it surely hid a harmful payload beneath.
Not like the precise Clawdbot service, which by no means launched an official VS Code extension, this imposter efficiently registered the identify first and tricked customers into putting in it.
The risk instantly caught the eye of safety monitoring techniques, which detected uncommon exercise the second VS Code launched.
The deception runs deeper than a easy identify theft. The extension functioned precisely like marketed, integrating with fashionable AI suppliers together with OpenAI, Anthropic, and Google.
This working performance created a false sense of safety, as customers had no motive to suspect malicious habits.
Inside seconds of set up, the extension started its assault, silently deploying malware onto Home windows machines with out consumer data or consent. Microsoft acted swiftly upon notification and eliminated the extension from its market.
Aikido safety analysts recognized the true nature of this risk after detailed investigation. They found that the extension contained code designed to run routinely each time VS Code began.
The JavaScript code established a connection to an exterior server to fetch configuration directions, which then downloaded and executed a number of malicious information disguised as official system elements.
An infection Mechanism and ScreenConnect Deployment
Essentially the most regarding side includes how the attackers weaponized official distant entry software program.
When executed, the dropper deployed ScreenConnect, a trusted IT assist instrument, configured to speak with attacker-controlled servers at assembly.bulletmailer.web on port 8041.
The attackers created their very own ScreenConnect relay server and pre-configured consumer installers, distributing them by the VS Code extension.
Victims unknowingly acquired a completely practical ScreenConnect consumer that instantly established distant connections to the attacker’s infrastructure.
A Rust-based DLL file supplied redundant supply functionality, fetching backup payloads from Dropbox disguised as a Zoom replace.
This multi-layered strategy ensured success even when major command-and-control servers have been disabled. The attackers employed three separate fallback mechanisms, demonstrating refined operational planning.
Customers who put in this extension ought to instantly uninstall it, take away ScreenConnect from their techniques, and block the infrastructure domains.
Rotating API keys for any AI companies accessed by the extension is strongly advisable. The risk underscores the significance of verifying extension authenticity earlier than set up.
