Microsoft Set To Pay First Bug Bounty For IE Hole

July 11, 2013 Paul Roberts

Weeks after launching its first, formal bug bounty program, Microsoft is set to issue its first monetary reward, according to a blog post by Katie Moussouris, the Senior Security Strategist at Microsoft’s Security Response Center (MSRC). Writing on Wednesday, Moussouris said that the company has received “over a dozen” submissions since it launched the paid bounty program on June 26, and that “I personally notified the very first bounty recipient via email today that his submission for the Internet Explorer 11 Preview Bug Bounty is confirmed and validated. (Translation: He’s getting paid.)” Last month, Microsoft announced its new policy to pay for information about serious vulnerabilities in its products. The company had long maintained that it provided other kinds of rewards for information on software holes – mostly recognition and jobs – and didn’t need to offer bounties, as firms like Google, The Mozilla Foundation and Facebook do. In launching the new […]

Android Founder: Install Base Fragmentation No Big Deal

July 10, 2013 Paul Roberts

Android owners who were hoping that Google might be on the cusp of cleaning up its balkanized install base won’t be cheered by the latest word from on high: Android co-founder and Google Ventures Partner Rich Miner thinks it’s no big deal. Speaking on Tuesday at an event in Boston, Miner said that fragmentation of the install base was inevitable, given the number and variety of Android devices that are being adopted, according to a report by Xconomy.com.The statement comes as Google is dealing with the fallout from a newly disclosed vulnerability affecting almost all Android platforms that could allow attackers to fool Android into installing and running compromised applications. Miner was speaking at a Mobile Summit forum hosted by the Massachusetts Technology Leadership Council. He made his statements while being interviewed by renowned technology journalist and columnist Scott Kirsner (@ScottKirsner) of the Boston Globe on the (evergreen) topic “What’s […]

Updated: Exploit Code Released For Android Security Hole

July 8, 2013 Paul Roberts

A security researcher has published what he claims is a proof of concept program that exploits a security hole that affects hundreds of millions of Android mobile devices.* Pau Oliva Fora, a security researcher for the firm Via Forensics, published a small, proof of concept module that exploits the flaw in the way Android verifies the authenticity of signed mobile applications. The flaw was first disclosed last week by Jeff Forristal, the Chief Technology Officer at Bluebox Security, ahead of a presentation at the Black Hat Briefings in August. Oliva Fora posted his “quick and dirty” proof of concept on GitHub, a code sharing website, on Monday. The simple program leverages APKTool, a common, open source tool for reverse engineering Android applications – decompiling and then recompiling their contents. APKTool is widely used for analyzing and making modifications to closed binaries. His script allows a user to select an Android […]

Security Must-Do’s For Facebook Graph Search

July 8, 2013 Paul Roberts

Facebook finally pulled the covers off its much-anticipated (or dreaded) Graph Search feature on Monday, after about six months in beta. The new search feature greatly expands the kinds of information Facebook users can access on other users of the social network, making it easy, for example, to cross reference data stored in Facebook profiles. For example, users can easily call up a list of their “friends who live in Boston” and like the show “Arrested Development.” Fun! But, as has been noted, Graph Search is also a social engineer’s dream, because it lays bare lots of information – data – that Facebook users shared, casually, and without a thought of how it might be used in combination with other data they shared. For example, researchers have shown that they can use knowledge of a Facebook user’s “Likes” to “automatically and accurately predict a range of highly sensitive personal attributes including: […]

Flaw Leaves 900M Android Devices Vulnerable

July 5, 2013 Paul Roberts

A security researcher claims to have uncovered a flaw in the Android security model that leaves almost all devices running the mobile operating system vulnerable to attacks and malicious software. Jeff Forristal, the Chief Technology Officer at Bluebox Security posted a description of the flaw on Wednesday. It affects Android devices running any version of the OS released in the past four years, starting with Version 1.6 (codename: “Donut” ) – a population of nearly 900 million devices. Discrepancies in how Android applications are cryptographically signed and then verified by Android allow a malicious attacker to modify the application package file (or APK) code without breaking the cryptographic signature. The implications of the flaw are huge. A malicious application installed on a vulnerable Android device could access any data stored on the device. For applications, such as mobile virtual private network (VPN), an attacker who could alter the application’s code or […]
