The myth of *nix security

>It’s often argued that *nix systems are secure, and there aren’t any viruses or malware for such systems. This hasn’t been true for a long time, as two recently detected malicious programs prove.
>The first is Trojan-Mailfinder.Perl.Hnc.a, a perl script which connects to a command server to get text and a recipient list for spam mailings.
>The second program is Trojan-Dropper.Linux.Prl.a, an executable for Linux and FreeBSD. The file decrypts the perl script, launches the perl interpreter and then gives it the decrypted script.
>This malware has been detected on servers infected with Trojan-Downloader.JS.Iframe.auy (shown in the screenshot below).
