ICANN Releases DNS Attack Factsheet Concerning Recent Attacks

ICANN has released a factsheet concerning the recent attack on the root server system on 6 February 2007. The factsheet is intended to provide an explanation of the attack for a non-technical audience and hopes to enlarge public understanding surrounding this and related issues.

Aside from covering the attack itself and the engineers' response to it, the factsheet also briefly reviews the root server system, the domain name system, Anycast technology, and what can be done in order to deal with such attacks in future. The fact sheet can be downloaded here [PDF]. more

Anti-DNS Google Desktop Attack Reported

Google's PC search software is vulnerable to a variation on a little-known Web-based attack called anti-DNS (Domain Name System) pinning, that could give an attacker access to any data indexed by Google Desktop, security researchers said this week.

...Anti-DNS pinning is an emerging area of security research, understood by just a handful of researchers, said Jeremiah Grossman, chief technical officer at WhiteHat Security. more

Researchers Say Attackers Can Hit Home Routers

If you haven't changed the default password on your home router, do so now. That's what researchers at Symantec and Indiana University are saying, after publishing the results of tests that show how attackers could take over your home router using malicious JavaScript code.

...In tests, the researchers were able to do things like change firmware and redirect a D-Link Systems DI-524 wireless router to look up websites from a DNS server of their choosing. more

Attack Seriously Slows Two Internet Root Servers

Online attackers have briefly disrupted service on at least two of the 13 "root" servers that are used to direct traffic on the Internet.

The attack, which began Tuesday at about 5:30 a.m. Eastern time, was the most significant attack against the root servers since an October 2002 distributed denial of service (DDOS) attack, said Ben Petro, senior vice president of services with Internet service provider Neustar Inc. more

Phishing Attacks Surpass Viruses and Trojans

Phishing attacks have outnumbered emails infected with viruses and Trojan horse programs for the first time, according to security experts.

...The difference in the ratio of phishing to virus attacks is partly due to virus attacks becoming more targeted and no longer occurring as one large outbreak. This includes the recent Storm Worm and Warezov attacks, according to MessageLabs. more

Legal Attack on ARIN Dismissed in Court

The American Registry for Internet Numbers (ARIN) has announced [PDF] that it has prevailed in a lawsuit that challenged ARIN's ability to allocate Internet Protocol (IP) number resources fairly. The lawsuit was brought by an individual - Gary Kremen - who sought to have a netblock of IP addresses transferred to him without agreeing to ARIN's standard terms and conditions.

"Today's victory is significant for consumers who rely on the Internet to operate efficiently and effectively," said ARIN President and CEO Raymond Plzak. more

Security Experts Warn VoIP Attacks May Be Just Around the Corner

It's become a familiar pattern in online security. A groundbreaking way to communicate emerges, spreads like wildfire, and then hackers find a way to use it to their advantage. Security companies react--but not before the problem has succeeded in wreaking havoc. It happened with e-mail and is happening now with instant messaging and mobile devices.

The next area that could be targeted: Voice over Internet Protocol, or VoIP, which lets people make low-priced phone calls using the same technology that delivers e-mail. And the results could be just as damaging, if not worse, than with other technologies, some security experts warn.  more

DNS Hackers Target Domain Registrars

Hackers have launched distributed denial of service attacks against the Domain Name System (DNS) servers of a brace of domain name registrars over recent days. The motive for the separate attacks against VeriSign and Joker.com remains unclear.

VeriSign said the attack on its name servers caused a "brief degradation" in the quality of its service to customers for around 25 minutes on Tuesday afternoon, ComputerWorld reports. Domain registrar Joker.com is recovering from an attack on its name servers last week that lasted for six days up until last Sunday. Joker.com, which is based in Germany, handles the registration of approximately 550,000 domains. more

DNS Servers Do Hackers' Dirty Work

"DNS is now a major vector for DDOS," Dan Kaminsky, a security researcher said, referring to distributed denial-of-service attacks. "The bar has been lowered. People with fewer resources can now launch potentially crippling attacks."

Just as in any DDOS attack, the target system -- which could be a victim's Web server, name server or mail server -- is inundated with a multitude of data coming from multiple systems on the Internet. The goal is to make the target unreachable online by flooding the data connection or by crashing it as it tries to handle the incoming data.  more

Phishing Attacks Evolved Steadily Throughout 2005 Security

Phishing attacks are continually evolving, as fraudsters develop new strategies and quickly refine them in an effort to stay a step ahead of banking customers and the security community. Here are some of the phishing trends and innovations we noted in 2005...

Open redirects became a favorite method for phishing attacks to "borrow" the URL and credibility of a trusted web site. Redirects are common on large web sites, where server side scripts are employed to redirect users to different parts of the site. more
