U.S. Cyber-security Leads Week in Security News
U.S. cyber-security was in the spotlight this past week when a senior Pentagon official confirmed an infected flash drive caused the "most significant breach of U.S. military computers ever."
Deputy Secretary of Defense William Lynn III discussed the 2008 incident in an article for Foreign Affairs magazine.
"That code spread undetected on both classified and unclassified systems, establishing what amounted to a digital beachhead, from which data could be transferred to servers under foreign control," Lynn writes. "It was a network administrator's worst fear: a rogue program operating silently, poised to deliver operational plans into the hands of an unknown adversary."
Lynn also discussed U.S. cyber-security strategy, and called for public and private partnerships to secure cyber-space.
On the subject of threats, the number of exploits circulating for the .DLL loading issue affecting scores of applications boomed during the week. Accompanying the increase in available exploits were revelations about some of the vulnerable programs, which include apps such as Adobe Photoshop and Microsoft Word 2007.
Actually fixing affected applications does not appear to be overly difficult, but the sheer number of vulnerable applications poses a challenge, Marc Fossi, manager of research and development for Symantec Security Response, told eWEEK. Raising awareness of among application developers is going to be a major hurdle, he added.
"According to Microsoft, directly addressing this issue in Windows will result in the loss of some expected functionality," he said. "As a result, they are recommending that the onus be on application developers to fix it. However, we encourage Microsoft to continue to look at ways to address this issue from a higher level."
A new threat report from Symantec named Rustock the most dominant spam botnet on the Web-a title it held despite a significant drop-off in the number of bots under its control.
On the subject of spam, researchers at Sophos and IBM noted an uptick of spam targeting users with malicious zip file attachments. Those who make the mistake of opening the attachments have been hit with everything from Trojan downloaders to variants of the infamous Zeus malware.
Researchers at IBM's X-Force also released a sweeping report during the week that found the number of vulnerability disclosures during the first half of the year shot up 36 percent compared with the first six months of 2009. The total number of bugs disclosed during the period was 4,396.
Leading the way with the most vulnerabilities was Apple, with Microsoft coming in at No. 2 and Adobe Systems at No. 3.
"The leap in vulnerability disclosures relates to organizations taking a greater interest in exploitable software bugs as well as attackers continuing to develop their own infrastructure," Tom Cross, manager of IBM's X-Force Advanced Research Team, said in an interview with eWEEK. "An area that both whitehat and blackhat security researchers are focusing on is automated vulnerability discovery through approaches such as fuzzing. Predicting disclosure increases into the future is going to be tricky for this reason, and we may see the occasional plateau or decrease."
