President Barack Obama issued a long-anticipated Executive Order for improving the nation’s cyber security late Tuesday. The Order, released on the same evening as President Obama addressed both chambers of Congress with his State of the Union Address called cyber attacks “one of the most serious national security challenges we must confront,” and put public and private owners of critical infrastructure in the U.S. on notice that they would need to work closely with the government to reduce the risk of crippling cyber attacks. President Obama issued the Order after Congress failed, in its last session, to agree on comprehensive cyber security legislation. Negotiations over the bill broke down over Republican amendments to a Democratic sponsored bill and concerns from the business community about the cost of complying with some of the more controversial provisions. Among those: a requirement that the Department of Homeland Security be able to audit […]

Bit9 Defends Response To Hack, Promises More Details
The security firm Bit9 defended its response to a hack of its own network last week and promised to release more information to the public about what happened – just not quite yet. In a blog post dated Saturday, February 9, the company’s CTO, Harry Sverdlove, said that the company responded promptly to the attack and contacted customers as soon as it completed its own investigation of the hack, which allowed unknown assailants to sign malicious programs using a Bit9 code signing server. That malware was subsequently released on networks of Bit9 customers. Sverdlove said the company’s “first and foremost priority was to inform our customers quickly and directly,” and that the company did so “as soon as we understood and had mitigated the attack, and we were able to provide actionable advice.” The blog post by Sverdlove, just a day after a post by Bit9 CEO Patrick Morley that disclosed […]
Whitelist Goes Black: Security Firm Bit9 Hacked
Application “whitelisting” offers an alternative to signature based malware protection. Rather than trying to spot the bad guys, the thinking goes, just identify a list of approved (whitelisted) applications, then block everything else. But what happens when the whitelist, itself, becomes compromised? That’s the scenario that’s playing out with customers of whitelisting firm Bit9, which acknowledged a breach of its corporate network that allowed unknown assailants to gain control of an application code signing server. The acknowledgement came after Bit9 was contacted regarding the breach by Brian Krebs of Krebsonsecurity.com, which broke the news Friday. Little is known about the incident. In a blog post, Bit9’s CEO, Patrick Morley, said that only three of the company’ s customers were affected. Those customers identified malware on their networks that had been signed by one of Bit9’s code signing servers. The lapse was the result of a breach on Bit9’s own network. […]
Wealthy Countries Better At Protecting Citizens…From Malware
To paraphrase a quote attributed to the great American novelist F. Scott Fitzgerald: ‘Rich countries aren’t like you and me. They have less malware.’ That’s the conclusion of a special Security Intelligence Report released by Microsoft on Wednesday, which found that the rate of malware infections was relatively lower in countries that were wealthy than those with lower gross income per capita. The study, “Linking Cybersecurity Policy and Performance” investigated the links between rates of computer infections and a range of national characteristics including the relative wealth of a nation, observance of the rule of law and the rate of software piracy. The conclusion: wealthier nations, especially in Europe, do a better job preventing malware infections than poorer and developing nations. The report marks an effort by Microsoft to dig into some of the underlying causes of cyber insecurity globally. Using data gathered from its Malicious Software Removal Tool (MSRT) […]
Researchers: Hole In TLS Encryption Could Expose Secure Web Sessions
Researchers at the University of London are going public with a paper that claims to have found a flaw in the specification for Transport Layer Security (TLS) that could leave supposedly secure Web, IM, VoIP and other online sessions exposed to prying eyes. The researchers, Nadhem Al Fardan and Kenny Patterson of the Information Security Group at Royal Holloway, University of London said that the security hole stem from a flaw in the TLS specification, rather than a bug in how TLS is implemented. The two researchers have developed proof of concept attacks that take advantage of the flaw, and that could be used to recover a complete block of TLS-encrypted plaintext, the researchers said. Al Fardan is a Ph.D student in the Information Security Group. Patterson is a professor of Information Security there. The two have discovered other, serious holes in TLS before. Notably: the two discovered a critical […]
