Could Ad Networks Power Massive, Browser-Based Botnets?

When it comes to security, the web is insecure-by-design. We’ve known that for a long time – what with “man in the middle” attacks like FireSheep, drive-by download attacks and more. The problem has always been how to scale web based attacks. At the end of the day, having an attack web page is great but, like every other website owner, you still have to figure out how to get people to visit your site! Now researchers at WhiteHat security say they’ve found an easy way around the “scale” problem: ad networks. In a presentation at Black Hat this week, Jeremiah Grossman, the CTO of WhiteHat Security, and Matt Johansen, the Manager of Threat Research there, will show how would-be attackers can parlay a small cash outlay into a sizeable browser-based botnet that could be used to send out spam, spread malicious code or launch denial of service attacks on other web […]

Android Founder: Install Base Fragmentation No Big Deal

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 […]

Flaw Leaves 900M Android Devices Vulnerable

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 […]

Don’t Call It A Hack Back: Crowdstrike Unveils Falcon Platform

Lots of aspiring technology start-ups dream of getting their product written up in The New York Times or Wall Street Journal when it launches. For Crowdstrike Inc. a two year-old security start-up based in Laguna Niguel, California, media attention from the papers of record hasn’t been an issue. This reporter counted twelve articles mentioning the company in The Times in the last year, and another two reports in The Journal. Much of that ink has been spilled on stories related to Crowdstrike research on sophisticated attacks, or the company’s all-star executive team, including former McAfee executives George Kurtz (CEO) and Dmitri Alperovitch (CTO), as well as former FBI cybersecurity chief Shawn Henry (Crowdstrike’s head of services), who left the Bureau in April, 2012 to join the company. For much of that time, Crowdstrike has been known mostly as a security services and intelligence firm, but the goal was always to […]

Fraud Analytics: You’re Doing It Wrong!

One of the most vexing problems in computer security today is distinguishing malicious from legitimate behavior on victim networks. Sophisticated cyber criminals and nation-backed hacking groups make a point of moving low and slow on compromised end points and networks, while victim organizations are (rightly) wary of disrupting legitimate business activity for the sake of spotting a breach. In this Security Ledger Podcast, Paul interviews Jason Sloderbeck, Director of Product Management at RSA, EMC’s security division.  Jason talks about RSA’s Silvertail fraud analytics technology, and the organizational and technology issues that keep victims from spotting attacks. One of the big mistakes organizations make when they investigate attacks, Sloderbeck said, is focusing too narrowly on a point in time during a web session that is felt to be a good indicator of compromise – like when a user authenticates to a service or “checks out” on an e-commerce web site. “There’s a whole […]
