Trojan Discourages Porn-surfing

Sep 6, 2005
Experts at SophosLabs, Sophos's global network of virus and spam analysis centers, have warned users about a Trojan horse which tries to interrupt surfing of adult websites by displaying messages from the Koran.

The Yusufali-A Trojan horse monitors the websites Windows users are visiting by examining the title bar of the active window. If the Trojan finds a word it doesn't like (such as "teen", "xx", "sex" or "penis") it minimizes the window so the user cannot see its content and displays a message from the Koran instead, which says - Yusufali: Know, therefore, that there is no god but Allah, and ask forgiveness for thy fault, and for the men and women who believe: for Allah knows how ye move about and how ye dwell in your homes.

"Unlike other malware, it appears this Trojan horse isn't trying to steal money or confidential information, but acting as a moral guardian instead - blocking viewing of websites it determines are unsavory," said Graham Cluley, senior technology consultant for Sophos. "Of course, it's possible for the Trojan horse to make mistakes and block sites which are not pornographic - such as medical sites, or social sites designed for teenagers." (or anyone trying to goto the superbowl 30 XXX website)

The Yusufali-A Trojan horse continues to display messages if the offending website remains open, and after a while it displays a button labelled "For Exit Click Here". As soon as the mouse is moved the box changes to have vertical bars and the text 'OH! NO i'm in the Cage'. The box contains Log Off, Shut Down and Restart buttons and the mouse pointer is locked within the confines of the box. All the buttons actually cause the computer to logout.

"This Trojan horse may have been written as a joke, or as a serious attempt to clean-up the habits of internet users," continued Cluley. "Whatever the reasons behind its creations, computer users should protect their systems with up-to-date anti-virus software, security patches and a proper firewall."

:blink wonder how long it'll be before something like this comes up from the RIAA, Christian colation, or PETA for people who goto sites "they" deem inappropiate.

still kinda fun though.

In a way, I think it's kind of intresting from the perspective of virus designers and hackers. Here they've been doing this stuff just to show they can, for illicit profit and information, for the awareness value and for the pure malicious value of it. And now, they've got hackers with a seemingly benign moral imperative. Pretty unusual in this day and age.

Ah, something from the good old days of viruses, where they were written for mischief, instead of for turning computers into spam zombies and stealing data.
