Preliminary analysis says...
If you were infected, you were lucky (this time):

Cleanup
=======
- disconnect system from network
- shutdown system
- power system down
- reboot system.
- apply patches (see above)
- reconnect to network and monitor system

The worm does not write to disk and stays in memory. A simple reboot will
clean an infected machine. Note that due to the high volume in traffic
this worm generates, any vulnerable system connected to the internet is
likely to be infected within minutes.

Major worm
Looks like a worm caused some problems yesterday, especially for South Korea. A Code Red variant - I didn't notice any slowdowns or mysterious log entries...
Called "Sapphire" or "SQL Slammer," the worm carries a self-regenerating mechanism that enables it to multiply quickly across the Internet, said Mikko Hypponen, manager of anti-virus research at F-Secure, the Helsinki-based computer security firm.

"It is so good at replicating that it generates massive amounts of traffic that will slow down networks," Hypponen said. "The end user never sees it. They only experience the slowdown on the Net."

Security experts blamed the worm for crashing almost all Internet services in South Korea.

AT&T releases physical lock vulnerability
Article on NYTimes (free registration), linked by Slashdot- Just making sure everyone saw this...

A security researcher has revealed a little-known vulnerability in many locks that lets a person create a copy of the master key for an entire building by starting with any key from that building.

"Security and Murder" -or- "Giving someone enough rope to hang someone else with"
From the latest edition of Security Under Scrutiny:

If we stop rewarding wannabe hackers with fame & power security WILL improve. To do otherwise is to give people like Perry and Horn cash rewards for killing more wives and quadriplegic sons and innocent nurses.

If that isn't an excerpt that catches your eye I don't know what is. In edition four of this debate encouraging series, sockz attempts to draw parallels between the dissemination of vulnerabilities by professionals to a publisher who was found in a court ruling to be held responsible for the birth of a hitman. While I ultimately disagree with the conclusions he draws, it is definitely an interesting read.

Major online scammer busted
From the NYTimes:
There were sham auctions on E-bay and Yahoo! Stolen credit cards from across the world. Shipments to more than 100 branches of the company Mail Boxes Etc. in places like North Dakota, New York and Texas. There were also hundreds of Federal Express deliveries to a company in Singapore.

"The primary suspect was creating a very confusing trail for all of us," an American investigator said. "This is one of the most sophisticated ones I've seen."

Last month, Pakistani and American investigators arrested Khurram Iftikhar, a 25-year-old Pakistani college dropout. The case, investigators say, demonstrates the increasing sophistication of Internet surveillance technology by investigators and the global reach of online fraud.
