Corporate computer threats 'moving to Adobe'

Security improvements in Office 2007 mean cyberattackers will focus on flaws in other desktop applications, security experts warn.

SAN FRANCISCO--The launch of Microsoft Office 2007 is likely to turn malicious hackers' attention to other desktop applications, experts have warned.

They are likely to begin focusing more attention on looking for vulnerabilities in software such as Abobe Systems' Acrobat Reader, security experts said at the RSA Conference 2007 here on Wednesday.

Today, most spyware and other "crimeware" applications target flaws in client-side applications, explained Jeff Moss, who founded the Black Hat and Def Con hacker conventions. These attacks involve sending an employee or home user a modified file, or a hyperlink to a Web download, that will compromise their system if executed.

"Office 2007 is much better architected, and the fine-grained capabilities are much better (than Office 2003), so you're going to see a lot less application attacks against Office. And because of that you're going to see less attacks against Vista that are successful," predicted Moss.

"So, where do the attackers go? Every other app that you are running. That's going to be Acrobat, and we've already started seeing that in the last couple of months. They just go for the lowest-hanging fruit," Moss said.

Moss added that Adobe has recently begun patching more quickly, because it has become more of a target for these attacks. In January, Adobe admitted that its PDF Reader application contained a major security hole, which exposes a user's hard drive to attack.

Attendees of the RSA Conference heard that crimeware is a rapidly growing threat facing both companies and individuals. Criminals are using Trojan horses, rootkits, keyloggers and other pieces of malicious software in a concerted attempt to steal personal data, log-in codes or banking details.

Doug Camplejohn, chief executive of Mi5 Networks, which sells antispyware products, cited analyst firm Gartner's prediction that 75 percent of businesses will fall victim to a piece of financially motivated spyware in 2007. However, he wasn't sure that the recent launch of Office 2007 will have a significant effect on the problem.

"Not everyone is going to move to Vista overnight. So there's going to be a broad period of time when there's a broad user base that is going to have the existing vulnerabilities to deal with," Camplejohn said.

According to Moss, a team of malicious hackers might spend a month working on a client-side exploit before releasing it, but may devote as much as nine months perfecting a server-side attack, trying to get it exactly right before launching it. If the attack relies on a previously unknown flaw, they may only have one shot before security vendors wake up to the problem and issue protection.

Because computer crimes often rely on an individual running an application or clicking on a link, education should be a key part of a company's defense strategy, some conference attendees said. Locking down nonessential applications to limit the company's exposure to danger was also recommended.

"If I've got a user who isn't supposed to go onto the Internet, why am I allowing them Internet access?" asked Andre Gold, director of information security at Continental Airlines.

Camplejohn agreed that a more prescriptive, proactive approach may be better. "User education is nice, but I think that for the most part it falls on deaf ears," he said. "What we find most effective is to basically slap someone's hand right when they're doing something--a screen pop-up that tells them 'You can't do this' because that's confidential data that's going out that door."

"In some cases, people don't know that's something that they shouldn't be doing. And also, they know someone's watching."
