According to BlockBeats news, on July 28th, according to SlowMist Cosine, a hacker group disguised itself as recruiting and posted false job information on the V2EX platform, attracting interviewees through attractive benefits. The organization induces interviewees to develop pages based on their pre prepared malicious code repository as project templates. Once the interviewee downloads and debugs the relevant code, the computer will be implanted with malicious software, which may result in the theft of cryptocurrency assets and various account permissions. This attack exploits the trust of job seekers in technical interviews and carries out cyber attacks through seemingly normal development tasks. Job seekers should remain vigilant when participating in technical interviews and avoid running code of unknown origin on personal devices. It is recommended to use virtual machines or sandbox environments for testing.
