Daily Debrief: Forty million card numbers compromised

It's the latest iteration of white collar crime. And it's expensive, destructive, and a serious nuisance for victims. I'm talking about credit and debit card theft via wireless networks. Recently, a multinational group of 11 was charged with stealing more than 41 million credit and debit card numbers.

The crime plays upon the vulnerability of a retailer's wireless networks. In a technique dubbed "war-driving," criminals cruise by stores, looking for holes in the security system so they can extract all the vital credit and debit card information. Once obtained, the numbers could be reprinted … Read more

Alleged TJX hackers charged

Eleven people have been charged with hacking major U.S. retailers, including TJX.

The hacks compromised more than 40 million people's credit and debit card details.

The defendants are based internationally: three from the U.S., one from Estonia, three from the Ukraine, two from the People's Republic of China, and one from Belarus. One individual is known only by an online alias, and his place of origin is unknown, the U.S. Department of Justice said Tuesday.

Albert "Segvec" Gonzalez, from Miami, was charged on Tuesday with computer fraud, wire fraud, access-device fraud, aggravated identity … Read more

Twitter targeted by malware attacks

Twitter's time has finally come.

The microblogging service, once the playground of the Web 2.0 digerati, is now mainstream enough to be targeted by online criminals.

Kaspersky Lab has uncovered a fake Twitter profile created solely for the purpose of infecting people's computers.

The profile, with an alias that means "pretty rabbit" in Portuguese, has posted a link that purports to be a pornographic video, but is instead Trojan software masquerading as MP3 files that steals data from the machine, according to the Kaspersky's Viruslist.com blog.

"If you click on the link, … Read more

Black Hat 2008 promises to be big

LAS VEGAS--Black Hat 2008 is bigger, and some might say better. Occupying most of the third and fourth floors of the convention hall at Caesars Palace, the conference started on Saturday with two- and four-day training sessions that continue through Tuesday.

The "public" part of Black Hat runs Wednesday and Thursday and features speakers in 15 separate tracks. One of the tracks will consist of Turbo talks of 20 minutes each. After those, there will an opportunity for the audience to talk with some of the speakers in a another room.

Wednesday starts with a bang with … Read more

New worm targets Facebook, MySpace

Just because a "friend" sends you something on Facebook or MySpace doesn't mean you should trust it.

A new worm is spreading via Facebook and MySpace, turning victims' computers into zombies on a botnet, Kaspersky Lab said on Friday.

Basically, infected machines are propagating the worm by sending messages via the social networks to friends in the network.

The messages look like they contain links to video clips. When clicked on they prompt the recipient to download an executable file that purports to be the latest version of Flash Player. Instead, it is the worm itself, infecting … Read more

The ethics of lock picking and telling

In 2004, a video circulated on the Internet showing how a standard Bic pen could be used to open the U-shaped Kryptonite bike lock. The company recalled the locks, replaced newer purchases, and changed the design for new locks. Problem solved, right?

Not exactly. Despite the fact that the problem had been revealed 12 years earlier in a British bike magazine, Kryptonite had continued to sell the locks unchanged. Angry customers filed a class action lawsuit that was settled in 2005, with Kryptonite offering to replace all affected locks or provide vouchers, and compensate people whose bicycles were stolen as a result of the lock being picked.

"If you don't make the problems public, the companies don't fix them and the consumers buy shoddy stuff," said Bruce Schneier, chief security technology officer at BT.

There's been plenty written about breaking into the virtual locks that safeguard sensitive data on the Web. But the picking of real-world physical locks is becoming an increasingly popular pastime for some. Enthusiasts have formed sporting clubs and hold regular competitions. Security researchers write books about how locks can be broken into and show how it's done on blogs and videos and at security conferences.

Naturally, lock manufacturers aren't happy. They argue that publicizing the vulnerabilities causes people to panic unnecessarily and puts the public at risk by giving criminals information they can use to break door locks, safes, and other secured assets.

But, just like third-party disclosure of vulnerabilities in software forces manufacturers to acknowledge security holes and patch them quickly, lock manufacturers will find they can't escape the scrutiny and will have to be held accountable for their products, experts say. … Read more

Apple releases patch for critical DNS flaw

Apple released a security update Thursday to users of its Tiger and Leopard operating systems to address a critical and well-publicized Domain Name System flaw, along with a dozen other updates.

The DNS flaw, which was first reported by Dan Kaminsky of IOActive on July 8, could allow attackers to redirect Web site visitors to any site they choose and present forged information. The DNS translates the common name of a Web site into its numerical IP address, and is therefore a fundamental component to the Internet.

During the second pre-Black Hat security conference Webinar on July 24, Kaminsky provided … Read more

Enterprise organizations must take note of the Kaminsky DNS flaw

If you haven't heard about the current DNS vulnerability, here is a Reader's Digest-like summary. Security guru Dan Kaminsky found a vulnerability that could give the bad guys a relatively easy way to redirect Internet traffic. For example: You might think you are logging on to Bank of America's Web site. But instead, some hacker may have just exploited a domain name system vulnerability and is now in control of your identity.

Kaminsky deserves credit for finding this flaw and alerting the Internet community so it could fix the problem. This effort is well under way, but … Read more

Disk encryption is no silver bullet, researchers say

SAN JOSE, Calif.--Disk encryption, which people rely on for protecting sensitive data on laptops, can fairly easily be foiled, security researchers said in presenting a paper on a so-called "cold-boot attack" at the Usenix security conference on Wednesday.

In a new type of attack that requires physical access to a target computer, an attacker can cut power to a machine that is in sleep mode, restore the power, and boot a malicious operating system from a USB drive or an iPod that can copy the RAM contents.

But won't the contents of the RAM be lost … Read more

Most drive-by malware comes from China, Google says

SAN JOSE, Calif.--A analysis by Google of Web sites that have malware found most of the malicious drive-by activity is due to computers in China, an engineer for the search giant said at the Usenix security conference on Wednesday.

About 67 percent of all the sites that secretly drop malicious software onto visitors' computers are located in China, as are 64 percent of the compromised servers, said senior staff engineer Niels Provos during a presentation here at the event.

"Web based malware is a significant problem and...there is no real good proactive defense against this," Provos … Read more
