 During last two weeks, security experts have registered several digital incidents provoked by a worm with Trojan capabilities that is infecting both Enterprise systems and home computers. The worm was named “Win32.Agent.wj’ and works by copying itself to the root folder of USB flash Drives, MP3 players and other removable storage devices in the computer. The worm creates then an ‘autorun.inf’ configuration file which enables the malicious code when the infected drive is inserted into another computer. Every time an infected computer is started, the worm too is run automatically and a text in Chinese is displayed on the desktop for some time. The Worm conceals itself with the help of Windows "SetFileAttributes" and tries to evade detection.The main purpose of malware writers is to infect as many computers as possible, but this specific worm seems to be affecting ” Enterprises particularly just as one and all have suddenly woken up to the exceptional convenience and easy portability that thumb drives offer. And no wonder it provides an equally easy mode of malware proliferation for Virus writers as well,” declared Govind Rammurthy, CEO of MicroWorld Technologies – the company that first detected the worm. Win32.Agent.wj belongs to the same family of USBToy.A, a worm that infected several computer last October , USB Toy A as well works by spreading itself through USB ports and once it is run, it also shows a message in Chinese. As demonstrated in tests and in everyday experience, USB flash drives really represent a risk in any Security System since on the one hand they could allow to steal information leaving no trace, and on the other they could be a vehicle for the spreading of worms and viruses.
