eEye Offers Free Scanning Tool to Detect Email Virus Infection
eEye® Digital Security released a free scanning tool to detect the MyDoom
email virus. This virus, which has propagated quickly, could significantly imp
act network services worldwide.
Systems Affected
All current versions of Microsoft Windows 95, 98, ME, NT, 2000, and XP.
Potential Impact
This mass-mailing virus targets from a list of email subjects, message bodies,
and attachment file names. The virus, once executed, spoofs the sender name o
f its messages so that they appear to have been sent by different users instea
d of the actual users of the infected machines. Upon infecting a computer, the
worm will set up a backdoor into the system by opening a TCP port (port 3127
or next available up to 3198), which could allow an attacker to connect to the
computer and gain access to its network resources. The backdoor could also al
low for the upload and execution of arbitrary files.
Severity Rating: Critical
According to MessageLabs Inc., which scans email for viruses, during the peak
infection rate one in every twelve messages sent over the Internet contained t
he virus, called "MyDoom" or "Novarg". Because of the enormity of this mass em
ail infection, every Windows machine that possesses email capability is vulner
able.
Combating This Virus
Please use an antivirus tool of your choice. The most effective way to identif
y affected systems is to scan using eEye’s Retina Network Security Scanner, o
r the free Retina MyDoom scanning utility, which was made available today at:
http://www.eeye.com/html/Research/Tools/MyDoom.html.
Retina Audits
Retina® Network Security Scanner has been updated to check for the email v
irus and its variants. These checks are included in Retina 4.9.155 and higher.
