Another new worm
started to circulate yesterday, called W32.Netsky.P@mm
(also known as W32.Netsky.Q@mm, Win32/Netsky.P@mm, Worm/NetSky.P,
W32/Netsky.P.worm).
This new NETSKY variant is very similar to the previous NETSKY variants
and to W32.Beagle.O@mm from yesterday's alert.
This memory-resident,
mass-mailing worm runs on Windows 95, 98, ME, NT, 2000 and XP.
It propagates
via email using its own Simple Mail Transfer Protocol (SMTP) engine.
It exploits
a known vulnerability affecting Internet Explorer (5.5 or IE 5.01
not patched with SP2 ), which allows the automatic execution of email
attachments while an email is read or previewed.
PLEASE
never use a Reading Pane or an AutoPreview
Pane unless your Windows Operating System is fully patched
with all the Critical Updates and Service Packs made available
to your PC by Microsoft.
It attempts
to propagate via network shares (Kazaa) by dropping copies of itself
on certain folders found in the affected system.
