Another Mac OS X Server Hack?

In a recent article, we reported on Tom Yager, a journalist for InfoWorld, who suspected that his Mac OS X server was hacked. Tom has since written about a root exploit he discovered, and now continues discussing this exploit and the effects it has had, turning his server into a spam zombie. Intego’s researchers believe this is the result of an OpenSSH vulnerability that has just been discovered, which affects multiple Unix- or Linux-based platforms. We would recommend that, until Apple patches this flaw, users keep an eye open, especially on their servers. Yager’s articles give a good idea what to look for.
