No rest for the Bagles

Last night was a busy one. Between yesterday evening and this morning, we intecepted 12 programs created by the authors of Bagle: 5 Trojan downloaders (classifed as Trojan-Downloader.Win32.Bagle.d – h) and 7 worms (Email-Worm.Win32.Bagle.eo – eu.)

All of this activity is with the aim of finding new machines to infect to keep the Bagle botnet running.
