Solaris worm! Experts at SophosLabs have warned of an internet worm that is exploting a recently announced vulnerability on Sun Solaris servers. The Unix/Froot-A worm (also known as Wanuk) exploits a vulnerability in both x86 and SPARC versions of version 10 of Solaris, attempting to open a backdoor which could allow hackers to gain remote access to computers. Under certain conditions the Froot worm can send system broadcast messages via the ‘wall’ command. These can take a variety of forms, including ASCII art and the phrase: Hi, I’m Casper, I am a bored Sun developer and I wrote this piece of code.
