Today, we received new worm mytob variants. It is kind of weird having a worm since the trend these previous months shows targeted attacks spamming trojan downloaders. Nevertheless, we are in the lookout for such threats.

We’ve received two variants of the worm and Trend Micro will be detecting them as WORM_MYTOB.JP and WORM_MYTOB.KJ. The pattern which includes the detections for these malwares will be available in the next CPR or OPR so be reminded to update your pattern files regularly.
