Networking Notes: Skype Says That Was No DDoS Attack

Skype responds to rumors that a band of criminal hackers brought down its VoIP service and more security updates. Plus: the latest networking product news.

Networking Notes

Security News

VoIP service Skype went down for a two-day outage late last week, knocking most of its 220 million subscribers off its network. In the absence of concrete information from the company, rumors initially flew that a band of criminal hackers had brought the service down through a massive DDoS attack. As it turns out, Skype said the problem was less exotic. The company claims the sheer volume of Windows systems rebooting after last week's Patch Tuesday crippled its authentication servers.

One DDoS attack that does not seem to be fictional: The Storm worm, which creates spam botnets, has taken to counterattacking computers scanning networks it has infected by activating its zombies and launching attacks on them. Security experts are concerned that a beginning-of-the-year security scanning regimen at colleges will trigger more attacks.

The organization that reported the attacks, REN-ISAC, offers an interesting security service: It tracks traffic over the Abilene network backbone and identifies which network ports are receiving the heaviest traffic, providing links to current exploits that target vulnerable applications listening on those ports. If you've ever wondered why your firewall reports a steady stream of requests to port 139, REN-ISAC has you covered>

A new Trojan called "Infostealer.Monstres" is targeting online job seekers and gathering information from users at such sites as Monster.com. Security researchers believe several hundred thousand users have had approximately 1.6 million pieces of data illegally harvested from Monster.com alone, with caches of data in several locations on the 'net that suggest many more users may have had their privacy compromised. The Trojans have taken advantage of vulnerabilities in Monster.com's Web servers to send personalized phishing messages to the site's users along with another Trojan masquerading as bogus copy of the site's Job Seeker Tool.
