Hackers can launch attacks over IM

Hackers can launch attacks over IM – ZDNet UK News
Security experts have discovered an instant messaging tool that could change the way denial-of-service (DoS) attacks are performed.
Combining the open-source tool nmap — a program that discovers devices on a network — with an IM bot, hackers can infiltrate, steal information and carry out denial-of-service attacks on networks, says the director of security for Whitehat UK, Jason Hart.
IM runs over port 80, which is often regarded as a trusted port because Internet traffic travels through it. Nmap uses ping requests and port scans to discover network devices.
