ACLU Complaint Shows Android Insecurity Getting Political

April 17, 2013 Paul Roberts

The American Civil Liberties Union has filed a complaint with the U.S. Federal Trade Commission on Wednesday calling on the Federal Government to take action to stem an epidemic of unpatched and insecure Android mobile devices – a public scourge that the ACLU blames on recalcitrant wireless carriers. The civil liberties group’s complaint for injunctive relief with the FTC, noting that “major wireless carriers have sold millions of Android smartphones to consumers” but that “the vast majority of these devices rarely receive software security updates.” Calling the unpatched phones “defective and unreasonably dangerous,” the ACLU says that carriers leave their customers vulnerable to malware and spear phishing attacks that can be used to record or transmit information on the device to” third parties. “A significant number of consumers are using smartphones running a version of the Android operating system with known, exploitable security vulnerabilities for which fixes have been published by Google, but have […]

EverNote Latest Site Hacked In Coordinated Attack

March 2, 2013 Paul Roberts

The online personal and business productivity service Evernote.com said on Saturday that it is the victim of a hack that exposed encrypted user password information, forcing password resets across a broad swath of the service’s 50 million registered users. The Redwood City, California-based firm revealed in a blog post that its internal security team discovered “suspicious activity on the Evernote network” that “appears to have been a coordinated attempt to access secure areas of the Evernote Service.” The company said it sent password reset messages to its users as a “precaution” but didn’t believe that stored information in users’ accounts or payment information had been exposed. The hack is just the latest of a prominent online firm. In recent weeks, Twitter, Facebook, Apple and Microsoft have all reported compromises of their internal networks. Those intrusions were linked to attacks aimed at developers and relied on exploits of previously unknown “zero day” […]

UPDATE: Vulnerability In EAS To Blame For Fake Zombie Apocalypse Warning?

February 13, 2013 Paul Roberts

Editor’s Note: Updated to include information on the brand of EAS device that was compromised. – PFR 2/14/2013 OK – the good news is that the dead aren’t rising from their graves and the Zombie Apocalypse hasn’t begun (yet…). The bad news: a phony EAS (Emergency Alerting System) warning about just such a cataclysm earlier this week may have been the result of a hack of what one security researcher says are known vulnerabilities in the hardware and software that is used to distribute emergency broadcasts to the public in the U.S. The warning from Mike Davis, a Principal Research Scientist at the firm IOActive, comes just days after unknown hackers compromised EAS systems at television stations in the U.S. and broadcast a bogus emergency alert claiming that the “dead were rising from their graves” and attacking people. Published reports say that at least four television stations were the victims […]

Bit9 Defends Response To Hack, Promises More Details

February 11, 2013 Paul Roberts

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 […]

Researchers: Hole In TLS Encryption Could Expose Secure Web Sessions

February 4, 2013 Paul Roberts

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 […]
