RSA Encryption 'Crack' Rattles Infosec Industry
A team of researchers say they've found a method for subverting RSA encryption. "This could be a big deal because there may be applications out there vulnerable to this attack," said John Hopkins' Matthew Green. RSA, however, contends the danger attributed to the research is being exaggerated.
Claims by a team of international cyrptographic researchers that they've "cracked" the RSA encryption used on a number of smartcards and secure tokens has set off a tempest in security circles.
The scientists from France, Italy, Norway and the United States have found a method for compromising the code in as little as 13 minutes. They plan to divulge more details in a paper they will present at the Crypto 2010 conference in August
"This could be a big deal because there may be applications out there vulnerable to this attack," Matthew Green, a professor specializing in cryptography in the computer science department Johns Hopkins University, told TechNewsWorld.
"I think it could be a serious problem, but I don't know of a concrete situation where it has allowed someone to attack a system," he added.
RSA, though, contends the danger attributed to the research is being exaggerated. "Our product isn't 'cracked,'" RSA chief technology officer for identity and data protection Sam Curry told TechNewsWorld.
"You can get some things off a device, but you can't get the private key," he said. "It doesn't let you clone it."
In public key cryptology, information is encrypted using a public key that's freely available to anyone. Information encrypted with a public key can only be decrypted with a private key that's paired to it. If someone could obtain a private key and make copies of it, or clone it, they could raise havoc with an organization's digital security.
Websites Getting Less Vulnerable
Despite the daily tattoo of reports about infected websites spreading malicious software, a study released last week by White Hat Security found that website security has been improving in recent years.
The study of some 7,000 websites found that the average number of serious vulnerabilities per site last year to be 79. That's a 65 percent drop over 2010, when the average was 230, and part of what has been a steady downward trend since 2007, when the average was a staggering 1,111 per site.
"Websites are notoriously riddled with vulnerabilities," White Hat founder and chief technology officer Jeremiah Grossman told TechNewsWorld. "Eight of 10 websites have something seriously wrong with them."
"Over time, though, the number of vulnerabilities we're finding in these websites is decreasing," he said. "That's a good thing."
One reason cited by Grossman for the decline in vulnerabilities is greater security awareness among developers. "Developers are getting better at writing more secure code and are seeing the importance in that," he observed.
Turning False Positives Into Sales
Events that attract global audiences, like the recently completed Euro 2012 soccer tournament or the upcoming Summer Olympics, can be both good and bad news for online retailers. The good news is the events can give their sales a boost. The bad news is the venues are magnets for cybercriminals.
To fend off digital desperadoes, many retailers put rules and policies in place to block suspicious orders. Those rules, though, are often too broadly crafted. That results is lost sales of legitimate orders, according to David Britton, vice president of industry solutions for 41st Parameter.
The attack rate from online miscreants on a retailer during one of these global events is less than one percent of retail traffic, he explained. Yet, he told TechNewsWorld, "We see as much as 7 percent of traffic being cancelled automatically and another 20 to 25 percent of traffic being held for suspicion of fraud."
"That amounts to an impact to your business of as much as 32 percent of either denied sales or delayed sales to solve a 1 percent fraud problem," he noted.
