David Banes, Regional Manager Symantec Security Response, Asia Pacific, analysis of the May data:
This month two new category three worms were discovered – Fizzer, and Sobig.B (Mankx) which rank in the top 5 on our
global and Asia Pacific threats list.
Fizzer, is a mass mailing worm that sends itself out to all contacts in your address book and also contains a tool that
logs key strokes which could potentially collect your passwords and PIN numbers. The worm also attempts to terminate the
processes of various antivirus programs if they are found to be active.
W32.Sobig.B@mm, a variant of the previously discovered Sobig worm, is also a mass mailing worm that sends itself to all
email addresses, and pretends to be sent from Microsoft with the subject line: (support@microsoft.com).
Although there are 2 new worms added this month, we are still seeing Klez and Nimda (discovered in 2001) ranking in the
top threats that are affecting consumers and corporations worldwide. Internet users, both consumer and corporate, need
to understand that in order to make sure that they are protected from old and new threats, they need to update their
antivirus definitions as well as keep their systems up to date with the latest patches.
