A radical Islamic group that is on the State Department's list of
designated terrorist organizations has claimed responsibility for the
release of the Slammer worm late last month.

In an exclusive exchange of e-mails with Computerworld spanning two
weeks, Abu Mujahid, a spokesman for Harkat-ul-Mujahideen (HUM), a
self-proclaimed radical Islamic jihadist organization, said the group
released the Slammer worm as part of a "cyber jihad" aimed at creating
fear and uncertainty on the Internet.

U.S. intelligence officials allege that HUM, formerly known as
Harkat-ul-Ansar, has ties to al-Qaeda and Ahmad Omar Sheikh, who was
arrested for the January 2002 kidnapping and murder of Wall Street
Journal reporter Daniel Pearl. The group operates primarily in Pakistan
and the Kashmir region, but it has also run terrorist training camps in
eastern Afghanistan, according to a U.S. Navy profile.

According to Mujahid, one of the worm's first instructions, a so-called
"push" command, includes the number 42, which is the sum of the letters
H, U and M if you add up the numbers that correspond to the point at
which each one falls in the Roman alphabet. H is the eighth letter; U is
the 21st; M is the 13th. When eight, 13 and 21 are added up, the total
is 42

However, Internet security experts were quick to dismiss HUM's claims of
purposely injecting a fingerprint into the code of Slammer as a way to
claim credit.

Pedram Amini, an analyst at iDefense, a security firm based in
Chantilly, Va., said the size of the worm is such that there is very
little room for any arbitrary fingerprints to have been included in the
code. In addition, the push command referenced by Mujahid and the
numbers that followed it are not something a coder could inject, but are
instead something generated by the execution of the code, said Amini.

"It is and has always been my opinion that the author of the worm cannot
be identified [by studying the code]," said Amini. HUM's claim of
injecting a fingerprint into the code "does not hold water," he said,
noting that the code that went into the worm could have been downloaded
from multiple locations on the Internet by anybody.

For example, according to iDefense analysts, a Chinese hacker group
called the Honker Union of China is known to have posted code similar to
that of the Slammer worm on its Web site prior to the attack. In
addition, proof-of-concept code released last August at the Black Hat
hacker conference by researcher David Litchfield is also believed to
have been used as a basis for the worm.

Bill Murray, a spokesman for the U.S. Federal Bureau of Investigation's
National Infrastructure Protection Center (NIPC), would not call members
of HUM suspects, but he did say that an NIPC analyst has looked into the
group in connection with the Slammer investigation.

"Do not underestimate our abilities to create fear and chaos on the
Internet, using programs we find and modify to our purposes," said
Mujahid. "We do not need to attack the infrastructure to terrorize the
Kufars," he said, referring to non-Muslims. "We use the Internet to
spread misinformation and confusion."
