N. Korea’s BlueNoroff Blamed for Hacking macOS Machines with ObjCShellz Malware

North Korea-linked hacking group BlueNoroff is suspected of creating previously undocumented macOS malware strain ObjCShellz, which is used in the RustBucket malware campaign. The group, a sub-elite of the notorious Lazarus Group that targets the banking and crypto sector, likely used the malware against a company in the cryptocurrency industry. BlueNoroff’s new development came shortly after the Lazarus Group was revealed to be using a new macOS malware, KANDYKORN, to target blockchain engineers.
