Method of treating whitespace during virus detection
Any of the inventors still work at NETA ?

biz.yahoo.com
A method is provided for detecting computer viruses that
infect text-based files. In accordance with a preferred
embodiment, a collection of virus signatures reflecting
sequences of characters or instructions known to be found
in such viruses is maintained on a computer system. A virus
detection program is also maintained for the purpose of
comparing the contents of computer files to the virus
signatures. Upon execution of the virus detection program,
whitespace within text-based files is transformed such that
each sequence of whitespace characters is replaced by a
single whitespace character. Virus signatures of viruses
known to infect text files are similarly transformed. A
transformed text-based file is then searched for at least
one of said virus signatures. The user is alerted to a
possible virus infection if any of the virus signatures are
found in a file. In another preferred embodiment, an
additional collection of at least one virus signature
containing sequences of characters or instructions known to
be found in viruses that infect executable computer files
is maintained on the computer system. A transformed text-
based file is searched for at least one of the additional
virus signature, which are not transformed before the
search.

WASHINGTON/SAN FRANCISCO)
By Elinor Mills Abreu
SAN FRANCISCO, July 31 (Reuters) - Security experts on
Tuesday saw no immediate effect on the Internet from the
dreaded "Code Red" worm that was expected to have begun winding
its way through Web servers in a renewed attack.
But experts also cautioned that more time was needed to
assess the impact of the worm's forecast outbreak, which had
been expected to start as global clocks ticked over to midnight.

ECONOMIC IMPACT
Computer security vendor Network Associates Inc. <NETA.O>
on Tuesday reported that it had scanned more than 20,000
systems and detected more than 1,230 servers that remained
vulnerable to Code Red shortly before thekey deadline for a
renewed outbreak.
Even as network security experts tracked the progress of
the bug, one research organization attempted an initial tally
of its economic costs.
Computer Economics, based in Carlsbad, California,
estimated that Code Red has already cost an estimated $1.2
billion in damage to networks, ranking it below last year's
Love Bug virus ($8.7 billion) but above the Melissa virus of
1999 ($1 billion) in terms of destructiveness.
The cost of clean-up, monitoring and checking systems for
the Code Red, which has infected about 360,000 servers, was
near $740 million, said Michael Erbschloe, vice president of
research at Computer Economics.
The loss of productivity associated with the worm was near
$450 million, he said.
"Information technology people are not cheap," he said. "A
lot of companies have outsourced this and they have to pay
sometimes $300 an hour to have people come in and look at their
servers." |

Code Red' Slams Thousands Of Sites
Bug Targets Web Servers
WASHINGTON, 4:33 p.m. EDT August 1, 2001 -- The "Code Red"
computer worm had infected about 80,000 Web sites as of 2:30 p.m.
ET -- prompting warnings that it could worm its way into a quarter of a
million of them within a day.
But there are also some encouraging signs. The
infection rates are slowing down with every
passing hour. And that's causing officials to be
more optimistic that they spread the word on
time, and that the final numbers won't be quite so
high. They've been calling on Web site operators
to install a software patch available from
Microsoft. When the worm -- which is like a virus
-- struck last month, it had only a day to spread
itself, before it turned to its next task of
targeting the White House Web site. This time,
it's expected to spend 20 days trying to spread.
There are fears that there could be a slowdown
across the Internet by the end of the day. But
officials are still hopeful that enough computers
have been inoculated to prevent major
interruptions. The head of research at a computer
security think-tank says the rate of infection
seems to be about what it was when the "worm"
first appeared last month. The worm, which is like
a virus, first appeared on July 19. It had just a
day to spread, before it went into attack mode
against the White House Web site. This time, it
has had the first 20 days of the month to spread.
The FBI says it's been spotted worldwide. It
doesn't target home computers -- just Web site
operators. But that can lead to slowdowns for all
Internet users. Early indications had been that
the worm hadn't turned into the Internet menace
it was feared to be. Then around 10 a.m. ET, CNN
reported that the FBI issued a warning that the
worm was starting to slow Internet traffic in
limited instances. The virus-busting CERT
Coordination Center reported at 8:30 a.m. ET that
the worm had gone active, as per predictions.
CERT "has seen evidence of exploitation and
scanning, and our staff members are currently
analyzing this activity. Early reports of activity
spanning the entire globe, including the United
States, indicate that the worm is presently
spreading throughout the Internet," the center
stated on its Web site. "As was the case in July
with its early progression, the worm's potential is
still unknown at this time." For updates from
CERT, click here After the warnings, many site
operators installed a software patch to ward off
the worm that was expected to re-emerge last
night. However, by early this morning there were
no indications that the worm was having any
major effect on the operation of the Internet.
Code Red infected several hundred thousand
computers during its first outbreak July 19. |
