Modernizing Authentication — What It Takes to Transform Secure Access
Roca-A, which also is known as Sober-D in some circles, was released into the wild onSunday and started hitting Germany and the United Kingdom right out of the gate. In thepast 24 hours, it has spread to other countries, including the United States.
The worm arrives in inboxes with the subject line: ''Microsoft Alert: Please Read''. Thebody message refers to the detection of a new MyDoom variant.
The ZIP file attached to the email carries the Roca-A worm, according to analysts fromSophos, Inc., a Lynnfield, Mass.-based anti-virus and anti-spam company. Once installed,the worm will present a phony message stating that the patch has been installed correctlyor that no patch was needed.https://o1.qnsr.com/log/p.gif?;n=203;c=204634421;s=15939;x=7936;f=201702151714490;u=j;z=TIMESTAMP;a=20304455;e=i The worm also is bilingual.
If Roca-A determines that it is being sent to a German email address, it will presentitself in German.
''As the Sober-C worm has shown in recent months, viruses which use more than one languagewhen communicating with users can be more successful at not raising suspicion,'' saysGraham Cluley, senior technology consultant for Sophos. ''Companies should ensure theiranti-virus software is automatically updated, and screen for dangerous filetypes at theiremail perimeter.''
This new threat hit the Internet just as a dramatic wave of viruses and variants appears tobe winding down. IT managers and the anti-virus community have been plagued over the lastfew weeks by a barrage of variants from the Bagle, Netsky and MyDoom families. Upwards of16 variants and new worms hit the Internet in a matter of weeks. As for the Bagle wormalone, seven variants were let loose within a 72-hour period.
The security intelligence firm mi2g, which is based in London, released a report thismorning calling last week's barrage of attacks ''historically unprecedented''.
So far, according to mi2g, the combined worldwide economic damage from Bagle, Netsky andMyDoom has crossed $100 billion. The company lists Sobig, MyDoom and Netsky as the mostdamaging malware in history.
The onslaught might have slowed slightly, but it certainly hasn't stopped.
In the last few days, Roca-A was joined by several other viruses, including the K and Jvariants of Netsky and the K variant of Bagle.
