OSX/Keydnap is a Mac-based malware that can steal passwords and execute remote commands on the Mac. Earlier this year, the BitTorrent client was used to spread a strand of Mac-related malware called KeRanger. It’s possible the site may have been hacked and then uploaded with a tainted version of the client, ESET said. The security firm has already removed the download, but users should check for signs that their Mac has been comprised. The malware was also spread through a Transmission client signed with a legitimate Apple developers certificate.”]
