Norton AntiVirus Protects Against Unknown Password-Stealing Trojan Horses
Cupertino, Calif --November 12, 1998-- Symantec
Corporation (Nasdaq: SYMC), the world leader in utility
software for business and personal computing, today
announced that the Symantec AntiVirus Research Center
(SARC) has developed Bloodhound for Trojan Horses to combat
the threat of unidentified password-stealing Trojan Horses.
Bloodhound for Trojan Horses joins Symantec's Bloodhound,
Bloodhound Macro, and Bloodhound Boot technologies to
provide Norton AntiVirus users with the most expansive
protection against new and unknown boot, file, and Word and
Excel macro viruses, as well as Trojan Horses. Bloodhound
for Trojan Horses is included with the current virus
definitions at Symantec's web site www.symantec.com.
"The security risks associated with Trojan Horses are
becoming more serious and widespread each day," said
Enrique Salem, vice president of Symantec's Security and
Assistance Business Unit. "With the addition of Bloodhound
for Trojan Horses technology, Norton AntiVirus customers
can be assured that they have the most powerful defense
against unknown password-stealing Trojan Horses as well as
protection from virus attacks from any source."
Approximately 90 percent of Trojan Horses found in
circulation today are from online services. Significant
numbers of Trojan Horses are designed to steal a user's
login ID and password and then e-mail it to someone else
who can make use of the account at the user's expense.
Other Trojan Horses may display obscene messages on the
user's screen or delete the contents of their hard drive.
Users typically get Trojan Horses by downloading a program
that seems safe or promises the user something like free
online time. Once it is downloaded and executed, the
malicious code begins to work. The difference between
Trojan Horses and traditional computer viruses is that
Trojan Horses do not replicate or spread on their own.
They can only be transmitted intentionally via e-mail or
diskette or downloaded directly onto a PC. This means
that, unlike a traditional computer virus, users are
typically only affected once by a specific Trojan Horse.
Bloodhound for Trojan Horses was developed to combat the
thousands of programs that steal passwords and credit card
information from AOL users. Such programs may ask an AOL
user to re-enter his or her password and credit card
information and then send that information to an
unauthorized third party. Because the majority of these new
Trojan threats contain malicious code that is similar to
existing threats, they can easily be detected using
heuristic technology. To that end, Bloodhound for Trojan
Horses uses a static heuristic method of detecting these
new Trojan Horses. Based on in-house testing, Bloodhound
for Trojan Horses is able to catch and then delete nearly
90 percent of these programs generically before they are
able to cause damage.
AOL users can be sure their systems are protected with
Bloodhound for Trojan Horses by simply updating their virus
definitions using the LiveUpdate feature in Norton
AntiVirus. LiveUpdate provides one-button access to new
virus definitions and engine updates from Symantec's
server. Bloodhound for Trojan Horses is available for all
versions of Norton AntiVirus, on all platforms. Norton
AntiVirus features a modular engine called NAVEX that
allows Symantec to ship fundamental changes and updates to
the engine technology across all platforms. LiveUpdate
delivers this engine, but NAVEX is what keeps these changes
small enough to download over the Internet.
