Google Warns Of Dodgy Digital Certificates Issued By India

Beware of Google domains bearing gifts – especially gifts from India. On Tuesday, Google’s Adam Langley took to the company’s security blog to warn about unauthorized digital certificates that have been issued by India’s National Informatics Centre (NIC) and used to vouch for “several Google domains.” Google notified the NIC, as well as India’s Controller of Certifying Authorities (or CCA) and Microsoft about the discovery and the certificates have been revoked, Langley said. As Cory Doctorow noted over at BoingBoing.net, most operating system vendors and browser makers don’t trust NIC-issued certificates as a matter of course. However, NIC holds intermediate CA (certificate authority) certificates that are trusted by India’s CCA, and CCA-trusted certificates are included in Microsoft’s Root Store, meaning applications running on Windows as well as Microsoft’s Internet Explorer web browser would have trusted the bogus NIC certificates. Google said that Chrome users on Windows would not have been victims of the […]

Microsoft Uses Courts To Take Down Malicious, Managed DNS Services

Microsoft Corp. has taken action against yet another cyber crime network, taking control of- and shutting down a managed DNS (domain name system) operated by the firm No-IP that were being abused by cyber criminals, the company said on Monday.   The domains were associated with malware families named Jenxcus and Bladabindi that are believed to have infected on some 7.5 million systems, globally. The malicious programs – which are used to spy on the operators of infected systems – use Dynamic DNS services like NO-IP to communicate with command and control systems used to manage infected systems. Dynamic DNS makes the malicious systems more difficult to trace. In a post on Microsoft’s Digital Crimes Unit blog, Richard Domingues Boscovich, the company’s Assistant General Counsel said that the company had filed a civil case on June 19 naming two foreign nationals: Mohamed Benabdellah and Naser Al Mutairi along with a U.S. company, Vitalwerks Internet Solutions, LLC (doing […]

Cisco: MS Word Macro Attacks Still Work Just Fine

We like to throw around the term ‘Advanced Persistent Threat’ casually these days to refer to a whole range of sophisticated and persistent attacks – usually on high value targets. But a blog post today by Cisco Systems makes clear that many otherwise sophisticated attackers do just fine with some pretty low tech and old school methods. Case in point: an attack Cisco is dubbing “String of Paerls-” a series of attacks on companies involved in research and what Cisco calls the ‘industrial manufacturing vertical.’ According to the report, the attacks start with a decidedly old school attack: a Microsoft Word document that includes a malicious Office Macro.”When the victim opens the Word document, an On-Open macro fires, which results in downloadin and executable and launching it on the victim’s machine.” Now, macro-based attacks are truly vintage. They first came to light in the late 1990s, with the Melissa virus – an early and successful […]

Big GOV Shift To Secure Cloud?

For those of us covering the cyber security beat, there haven’t been many feel-good stories coming out of the federal government in – well – forever. Even before the advent of nation state sponsored hacking, the news was mostly of the federal government’s bloated and unwieldy IT infrastructure, byzantine procurement systems and the difficulty of attracting top talent away from private sector employers who could offer more pay, more autonomy and a better working environment.   Then came the gut wrenching display of offensive prowess by the U.S.’s main enemies – nations like China, Russia and Iran. Those stories started, in earnest, with news about operations like Titan Rain (in 2003) and continue to the present day. The problem has gotten so bad that the military’s preferred euphemism for Chinese hackers – “advanced persistent threat,” or “APT” has become part of the nomenclature of the IT security world far beyond […]

Cisco: Microsoft Silverlight Exploits Fueling Drive-By Attacks

Cisco Systems is warning that Silverlight exploits are being used in a rash of drive-by-download attacks, many tied to malicious advertising (or ‘malvertising’) campaigns. Writing on Cisco’s blog, Levi Gundert of Cisco’s Threat Research Analysis and Communications (TRAC) team said that Silverlight exploits are the “flavor of the month” and have been added to the popular Angler exploit kit since late April. “Since April 23rd we have observed substantial traffic (often from Malvertising) being driven to Angler instances partially using Silverlight exploits,” Gundert wrote. Attacks leveraging vulnerable instances of Silverlight are actually outstripping attacks against Java and Adobe Flash – the two platforms that have long been the preference of cyber criminal groups and exploit kit authors. Silverlight was the subject of a patch in March, MS04-014, to fix a vulnerability that could allow remote attackers to bypass a security feature. The vulnerability would allow an attacker who controls an attack website to launch specially […]
