Contagious Interview evolves: attackers abuse VS Code Tasks to auto-run malware when a “trusted” workspace is opened
Taiwan’s TWCERT/CC reports a technical evolution in the “Contagious Interview” campaign: instead of relying on victims to manually execute a file, attackers embed a malicious VS Code workspace configuration so code runs automatically when developers open a project folder in Trusted Mode. The technique abuses VS Code’s tasks.json automation (including a run-on-folder-open behavior) and social engineering around Workspace Trust prompts. The activity primarily targets cryptocurrency software engineers and freelancers via recruiting outreach on LinkedIn and gig platforms, then directs them to download test projects from GitHub/GitLab. TWCERT/CC says the resulting payload has been identified as a newer BeaverTail variant (Type 701), with noted functional overlap with OtterCookie (sometimes referred to as “OtterCandy”), and is focused on stealing crypto-related browser extension and wallet data as well as high-value browser-stored secrets.
