ACSC Warning: Fake Job Interviews Can Put Malware on Your PC

Australia’s cyber security agency warns that fake job interview malware is targeting IT professionals’ computers. A joint advisory published on 18 September describes the WaterPlum or Contagious Interview campaign, which can begin with an apparently attractive role and a request to run a technical exercise or install software.

The interview can be the entry point

The ACSC-published advisory describes actors posing as employers and directing candidates to download and execute malicious files during recruitment. Coding assignments and supposed fixes for video-interview problems are among the pretexts. The warning concerns credential and data theft as well as cryptocurrency.

A convincing profile or a familiar code-hosting website doesn’t establish that an assignment is safe. Pause when a recruitment task asks for unusual software installation or execution on a machine holding personal or work accounts. Verify the employer through a separately obtained contact channel before proceeding.

If you already ran a file, record the sequence

Write down when the conversation happened, what you downloaded, what you ran and which accounts were open on the computer. Preserve the recruiter’s messages and the download links without reopening the files. That history gives an IT responder or repair technician something concrete to investigate. “The laptop feels slow” leaves out the most relevant part of the incident.

For a work-managed device, contact your organisation’s IT or security team promptly and follow its incident process. For a personal device, use a separate trusted device to obtain help. The Australian cybercrime reporting service provides a route to report an incident. Tell the responder about potentially exposed accounts as well as the computer itself.

A clean-up needs to address what may have been taken

The advisory warns that removing detected malware doesn’t establish that stolen information is safe. It also notes that undetected malware may remain. Ask a repairer what its assessment covers and whether specialist incident-response help is appropriate; don’t treat a quick scan as proof that every account and device is secure.
