Sophos experts have warned users to be wary of unexpected emails
from their friends speaking Spanish. A new worm, W32/Nicehello-A has
caused a number of enquiries to Sophos's support centres, but is
not expected to spread far due to bugs and its reliance on Spanish
phrases.
"Nicehello is another reminder that users should be cautious of
all email attachments, even when they know who the sender is," said
Graham Cluley, senior technology consultant at Sophos. "Think
before you click - ask yourself 'why is Ken from Walsall writing to
me in Spanish?'"
The W32/Nicehello-A worm invites users to launch an executable
file attached to the email. The worm is capable of stealing account
and password information from the infected user's MSN account.
Sophos recommends companies consider blocking all Windows
programs at their email gateway. It is rarely necessary to allow
users to receive programs via email from the outside world. There
is so little to lose, and so much to gain, simply by blocking all
mailed-in programs, regardless of whether they contain viruses or
not. Sophos MailMonitor for SMTP
contains pro-active threat reduction technology which can help
businesses block dangerous filetypes and executable code at the
email gateway.
Sophos customers who have kept their anti-virus software
up-to-date are automatically protected against W32/Nicehello-A.
Users of other anti-virus products are recommended to update their
software.
