Klez tops virus charts - again
By John Leyden
Posted: 01/07/2002 at 17:02 GMT
Variants of the Klez worm were by far the most common viruses
circulating on the Internet this month, Again.
That's according to monthly statistics from managed services
firm MessageLabs, which stopped 788,137 copies of the virus
in June, compared to 524, 507 in May.
Virus infection rates are currently running at around one per
240 emails, which compares to one in 30 infected emails at the
heights of the Goner and Love Bug epidemics, MessageLabs reports.
Klez became the worst virus ever in May, and it shows no sign of
abating, according to the firm
Other viruses were much less common. The next most common virus,
Yaha, was blocked only 67,146 times by MessageLabs during the
last four weeks. However Yaha has become a major irritant at
Vulture Central because of its capacity to spew hundreds of
infectious emails to a single address from infected machines.
Very irritating.
Klez cleanup
Klez is a mass-mailing worm which searches the Windows address
book for email addresses and sends messages to all recipients
that it finds. The worm uses its own SMTP engine to send the
messages. It can also spoof the 'From' in messages, a factor
which has resulted in widespread confusion about the bug.
The subject and attachment name of incoming emails is randomly
chosen, making it harder for users to spot. The attachment will
have one of the following extensions: .bat, .exe, .pif or .scr.
Klez is capable of infecting files.
The worm exploits a vulnerability in Microsoft Outlook and
Outlook Express in an attempt to execute itself when you open
or even preview the message.
Top ten viruses blocked by MessageLabs in June
1. Klez-H
2. Klez-E
3. Yaha-E
4. SirCam
5. VBSWG.AQ
6. Magistr-B
7. Hybris-B
8. Magistr-A
9. Yaha-C
10. Frethem-F
So there you go ! Please ALWAYS ensure that your AntiVirus Software
is up to date, Dont get caught out!!!
