On 7th October 2004, Kaspersky Labs virus analysts detected a new version of Opasoft, Worm.Win32.Opasoft.s.
The worm is now showing increased activity in Russia.
The worm uses accessible network resources to spread via local networks. It also contacts the site of a Ukrainian mobile services provider in order to send sms messages containing the IP addresses of victim machines.
A detailed description of Worm.Win32.Opasoft.s is available in the Virus Encyclopaedia.
Protection against Opasoft.s was included in the updates to antivirus databases the day the worm was detected.
