“Antivirus software companies are warning that a new version of the NetSky e-mail worm is circulating on the Internet, only a day after the appearance of a new variant of the Beagle or ‘Bagle’ worm prompted similar warnings,” Paul Roberts reports for IDG News Service.
“NetSky.B, also known as Moodown.B, first appeared today and is spreading through infected e-mail messages and shared network folders. Once installed, NetSky tries to disable antivirus software, steal e-mail addresses and copy itself to shared network folders, antivirus companies said,” Roberts reports.
“The new worm is a modified version of NetSky.A, which appeared on Monday. Like its predecessor, NetSky.B arrives in e-mail messages that have randomly generated subject lines such as ‘something for you,’ ‘hello’ or ‘fake.’ The worm file is contained in a zipped attachment that also has a randomly generated name and file type such as ‘document’ ‘stuff’ or ‘party.’ File attachments with an .exe, .scr or .pif extension are also common, said antivirus company TruSecure Corp.,” Roberts reports.
