Headlines about “advanced persistent threats” and targeted attacks have organizations of all sizes concerned. Barely a week goes by without news of a new, stealthy campaign targeting executives, government leaders or platforms used by prominent organizations. But while APT-style and targeted attacks may have the attention of the boardroom, organizations still face a Herculean task determining when an attack they’ve detected is targeted, and when it is merely indiscriminate. To help answer that question, I “hung out” with two experts in detecting and analyzing malicious threats to enterprises. Anup Ghosh is the CEO and co-founder of Invincea, which makes malware detection tools that isolate threats on endpoints. Matt Hartley is the Senior Director, Intelligence Lab Services at iSIGHT Partners, a cyber threat intelligence firm. Both told me that, while targeted attacks are on the rise, awareness about them is also at an all time high. That can, sometimes, result in organizations […]

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 […]
Browser Plug-in Steals Facebook Logins, Pumps Spam For GM Cars
Microsoft is warning users of Google’s Chrome and The Mozilla Foundation’s Firefox web browsers that a malicious browser extension for those platforms attempts to steal Facebook account login information after it is installed. The attacks have mostly occurred in Brazil, Microsoft, and have been linked to spam campaigns promoting GM cars, like the Chevy Celta, an ultracompact car produced by General Motors do Brasil, according to a post on Microsoft’s Technet web site. Microsoft identified the malware bundled with the browser extensions as Febipos.A, a malicious Trojan. After being installed, the Trojan waits for the user to log in to Facebook before it springs to life. Febipos downloads commands from a remote website that instruct it to carry out a wide range of actions through the active Facebook account, including wall posts, sharing and “liking” pages, commenting on other users’ posts and inviting Facebook friends to a group chat. You […]
Hacked WordPress Plug-in Put On Double, Secret Probation
A plug-in that was pulled from the official WordPress plug-in directory has been restored, but will be monitored closely, after the plug-in’s owner claimed a rogue contractor introduced malicious code into the popular web publishing add-on. Social Media Widget, a free plug-in for the WordPress blogging platform with more than a million downloads, was restored to the WordPress.org official plugin directory on Thursday, days after it was found injecting WordPress websites with spam links to web sites offering Pay Day Loans. In a post on a support forum for Social Media Widget, Samuel Wood, a WordPress administrator, said that WordPress.org was willing to give the owner and the plug-in, Brendan Sheehan, a second chance. “Naturally we do take a very hard line on spam, and obviously an author putting malicious code into a plugin is enough grounds for us to bring down the ban hammer,” Wood wrote on Friday. “But […]
Anti-Social: Popular WordPress Sharing Plugin Linked To Payday Loan Spam
A popular plug-in for sharing blog content on social networks was discovered to have hidden code that was injecting WordPress blogs with links to phony Pay Day Loan offers and other spam, according to the firm Sucuri. The plug-in, named Social-Media-Widget (SMW) was compromised with malicious code 12 days ago, in concert with an update of the widget. The new version of the plug-in contained a hidden call to a remote PHP script that inserted “Pay Day Loan” spam text and links into WordPress web sites running the plugin. The goal was to infect as many web sites as possible with text that would increase the web reputation and visibility of a web site run by the spammers, according to the post on Tuesday, by Daniel Cid, Sucuri’s CTO. SMW is among the most popular add-ons for Wordpess sites. It allows bloggers who use WordPress to configure sharing buttons that will […]
