April 26, 2006

It used to be, back in that last century, that people wished for a reverse time machine. This would allow them to go back in time after they messed up their computer.

Well, Windows XP has that time machine. And when some awful thing gives your computer the staggers, it's easy to go back to the day before. Or the day before that. Or last week or last month. It's an all-too-often unused feature that may save your bacon someday, called System Restore. Here are four things to know about it.

Pirates still roam freely in the ocean of software out there, but if your business is among the pirates, it could end up costing you literally and figuratively.

You may very well be a smart, community-minded business owner. But if your company is using pirated software â€" and you condone it, you aren't aware of it or you don't really give a rip â€" you're not a responsible business owner. And you are taking unnecessary risks. No, you're not alone. In the United States, about one-fourth of the software programs used today by businesses are illegal copies, according to the statistics from the Business Software Alliance (BSA), an active industry group. For U.S. small businesses, those with 100 or fewer employees, the piracy rate is even higher: about 40%. While those numbers are bad enough, the piracy problem worldwide is worse â€" although software piracy worldwide has decreased since 1994, some $13.08 billion was still lost in 2002 due to pirated software.

Circuit City warns of online forum attack

Part of the Circuit City Web site was hacked and used in an attempt to install malicious code on PCs of unknowing visitors, the electronics retailer said Thursday.

Cybercrooks were able to break in and modify a home theater message board on Circuit City's Web site, said Bill Cimino, a spokesman for Circuit City of Richmond, Va. Over an approximately two-week period, visitors to the board were subsequently sent to a site in Russia that attempted to install a "backdoor" on their PCs that gives the attackers remote access, he said. Circuit City was made aware of the attack on Thursday by the SANS Internet Storm Center, Cimino said. The company took down the message board, operated by a third party, and is in the process of notifying the 1,000 or so registered users of the online forum, he said. "At this point we think approximately 200 users visited the site while the exploit was active," Cimino said. Those people are registered users of the message board. Circuit City has no data on people who visited the site without being registered, he said.

Security experts warn of two flaws in IE, and in an unusual twist, one of them can be replicated in Firefox.

Two new security flaws have been discovered in Microsoft's Internet Explorer, and one could also affect Mozilla's Firefox, security experts have warned. Code for both the vulnerabilities has been published, but there have been no reports of attacks taking advantage of the flaws , the SANS Internet Storm Center, which monitors network threats, said in an advisory released Wednesday. The flaw that affects both IE and Firefox is related to the handling of a technology that is used to access documents delivered from one Web site to another, according to the advisory.

At least one developer account has been compromised a while ago and has been used by an attacker to gain access to the Debian server. A recently discovered local root vulnerability in the Linux kernel has then been used to gain root access to the machine. At 02:43 UTC on July 12th suspicious mails were received and alarmed the Debian admins.

Hacked Ad Seen on MySpace Served Spyware to a Million An online banner advertisement that ran on MySpace.com and other sites over the past week used a Windows security flaw to infect more than a million users with spyware when people merely browsed the si

Michael La Pilla, an iDefense "malcode" analyst, said he first spotted the attack Sunday while browsing MySpace on a Linux-based machine. When he browsed a page headed with an ad for DeckOutYourDeck.com, his browser asked him whether he wanted to open a file called exp.wmf. Microsoft released a patch in January to fix a serious security flaw in the way Windows renders WMF (Windows Metafile) images, and online criminal groups have been using the flaw to install adware, keystroke loggers and all manner of invasive software for the past seven months. The Deckoutyourdeck ad launching the WMF exploit.

Researcher: Hacker Sophistication Outpacing Forensics

August 9, 2006

In the never-ending cat-and-mouse game between hackers and those charged with stopping them, it's pretty clear who's winning--and it's not the cat.

Speaking at the Black Hat conference in Las Vegas last week, Kevin Mandia, president of Mandiant, an Alexandria, Va.-based security consultancy, said attackers are using increasingly sophisticated methods to evade detection and make life difficult for security incident response teams. The sophistication of hackers' tools is outpacing that of investigators' forensic tools, and one of the consequences is that incident response teams charged with investigating attacks on networks are taking between 5 and 8 days to find malicious code, Mandia said. "Malware analysis can be time consuming, and most firms don't want to spend the money to fully analyze the malicious code, which could cause further damage [to the network]," said Mandia.

The key indicator is a repeat "problem child" who continually argues with fellow employees, complains about salary or benefits, or is otherwise aggressive or hostile.

Brian Robak, a network security analyst at National Cooperative Bank, used to manage the company's help desk workers back when he was the LAN manager. Being a manager is never an easy chore, but there was one employee who generally made his job a nightmare. A full 80% of people who launch a computer-related attack on their own company's system had been problem employees, according to the Secret Service.
