Though in the whole 2005 seem by way of virus activity extremely quiet, any is valid epidemics, upon the termination dawn virus writers have decided "to celebrate": under the electronic correspondence virus Sober-Z "skips". Last week on it 60 % of messages on the infections registered Sophos were infected. Now those already 85 %.

By the current moment Sober-Z appears the third on number of infections (on first place Netsky-P, on the second - Zafi-D). Anti-virus experts are disturbed with that circumstance that the quantity of infections not only does not decrease, and on the contrary grows.

Appeared somewhere in area on November, 22nd, the "new" worm uses old, kind, time-tested means, - namely social engineering. However, original enough: for example, one of variants pretends to be inquiry from FBI where the addressee accuse of visiting illegal sites and demand to answer a certain list of questions, which (certainly!) ostensibly is in an investment.

Other variants pretend to be videoclips with participation notorious Peris Hilton which hackers for some reason especially "loves" also Nicole Richi.

After infection the worm scans a hard disk in searches of all possible e-mail addresses to dispatch on them the copies, and at the same time tries to close processes of antiviruses and fireproof walls.

Under statements of employees Sophos though the majority anti-virus was already let out with the updating exterminating a virus, the main problem consists in all users against whom social engineering is still rather effective.
