- An individual in Canada was targeted by a fake job interview scam from a fabricated persona claiming to represent a defunct Singapore-based VC, aimed at backdooring their machine, likely due to their packages on crates.io.
- The attacker used a TypeScript repository named 'Ticket Harbor' with a malicious patch (typescript+5.9.2.patch) that injected obfuscated code to execute a remote-access trojan (PinpinRAT) upon running typecheck or build commands.
- PinpinRAT harvests system info (IP, username, OS), uses RSA and AES encryption for C2 communication, supports commands like file upload/download, process spawning, and self-removal, with indicators including C2 IP 89.124.107.161 and persistence mechanisms.
- Red flags included subtle LLM-generated email tells, a LinkedIn profile with gibberish credentials, lack of proper calendar invites, and inconsistencies in the attacker's story, but the attack was sophisticated enough to potentially deceive developers.
- The incident was reported to Canadian agencies, and while the attacker's identity is unknown, it highlights targeted threats to developers, emphasizing vigilance against social engineering and code execution traps in repositories.
