“The FBI and security site Packet Storm have posted software
that can detect whether a site is being attacked. Once an attack is
identified, Web site managers can implement plans to deflect the
crippling amount of traffic generated by the assault.”
“The FBI’s tool examines programs on a computer for ‘signatures’
that indicate the presence of the attack software, much like the
way antivirus software looks for telltale signs.”
“Those who download the FBI’s software ‘are asked to report
significant or suspected criminal activity to their local FBI
office or the NIPC Watch/Warning Unit, and to computer emergency
response support and other law enforcement agencies,’ the FBI said.
… Computer forensics–the electronic equivalent of dusting
for fingerprints–can help identify who launched an attack and
how.”
