Affects: SentinelOne researchers discovered a typosquatting attack imitating the legitimate ‘rust_decimal’ crate used for financial calculations. The attacker's intent is that developers would misspell the legitimate crate name and download the malicious one ‘rustdecimal’ instead. The malware then identifies the victim's platform (macOS or Linux) and downloads the requisite Mythic Poseidon payload - a well-known post-exploitation red-teaming framework.
Such attacks are not uncommon on macOS. Recently the PyMafka malware leveraged a similar typosquatting technique hosting a malicious Python package named ‘pymafka’ in an attempt to imitate the legitimate ‘pykafka' package repository used by developers.
