Stration worm masquerades as security patch
A new version of the Stration worm has been engineered to infect computers by posing as a computer update, a security vendor has warned.
Sophos said that its latest reports showed that Stratio-AN is "rapidly spreading".
"The Stratio-AN worm has been aggressively distributed by its author since the early hours of Monday morning," said the firm in a statement. "It spreads via email using a variety of disguises, including an example which ironically poses as a warning that the recipient's computer is infected by a worm."
One version of Stratio-AN uses the email subject line 'Mail server report' and warns users that their PC is sending out emails containing the worm.
The bogus customer support service email contains a zipped file with the name 'Update-KB7859-x86.zip', which installs the worm on the user's PC.
