Hi all. You may want to be ready for a *possible* support lines flood today. Yesterday I discovered a fast-spreading facebook worm. It spreads by sending messages to all your facebook friends, from your account, asking them to click on a link in the .pl ccTLD. This worm is somewhat similar to zlob, here is a link to a kaspersky paper on a previous iteration of it, they call it koobface: http://www.kaspersky.com/news?id=207575670 The worm collects spam subject lines from, and then sends the users personal data to the following C&C: zzzping.com I spoke with DirectNIC last night and the Registrar Operations (reg-ops) mailing list was updated that the domain is no longer reachable. That was very fast response time from DirectNIC, which we appreciate. The worm is still fast-spreading, watch the statistics as they fly: http://www.d9.pl/system/stats.php The facebook security team is working on this, and they are quite capable. The security operations community has been doing analysis and take-downs, but the worm seems to still be spreading. All anti virus vendors have been notified, and detection (if not removal) should be added within a few hours to a few days. For now, while users may get infected, their information is safe (unless the worm has a secondary contact C&C which I have not verified yet). It seems like some users may have learned not to click on links in email, but any other medium does not compute. Gadi.
