Â Dear Readers,
So far, 2002 has been a year marked with variations on earlier
worms. If you update your antivirus software on a regular basis,
these new versions of Frethem and Yaha shouldn't be a nuisance.
But if you haven't updated in a while, these variants--plus the
continuing threat of Klez.h--should motivate you. In security
news, a flaw in certain versions of PGP encryption could affect
Outlook users. Read on to learn whether you're vulnerable.

Frethem.k worm wants to give you a password
 An e-mail message that promises to reveal secret information with
a password is yet another variant from the pesky Frethem worm
family. Frethem.k, technically known as w32.frethem.k@mm, also
called Frethem.l by some vendors, uses its own SMTP engine to
send e-mail using addresses obtained from infected systems. This
worm does not carry a destructive payload. Mac and Linux users
are not affected.Yaha.e screensaver worm spreading
 The Yaha.e mass-mailing worm masquerades as a friendly
screensaver, proving that users worldwide are still opening
attached files from total strangers. Yaha.e (w32.yaha.e@mm, also
known as Lentin.e, Yaha.f, and Yaha.g) is a successful variant of
a worm first seen around Valentine's Day this year. Thankfully,
this worm does not affect Mac, Linux, or Unix users.
Leaky PGP Outlook plug-in 
PGP 7.03 and 7.04, widely used plug-ins for Microsoft's Outlook
e-mail client, inadvertently weakens security and leaves the mail
program open to attack. Fortunately, there is a patch available.
