Gameover Not The End: Zeus Malware Still Threatens Fortune 500

Prolexic, a division of Akamai, issued an advisory to Fortune 500 firms on Monday about what it calls “a high-risk threat of continued breaches from the Zeus framework.” The company’s Security Engineering & Response Team (PLXsert) said on Monday that it has observed new payloads from the Zeus crimeware kit in the wild, and that networks of Fortune 500 companies are a prime target. Cyber crime groups are using Zeus to steal login credentials and gain access to web-based enterprise applications, as well as online banking accounts, Akamai warned. “The Zeus framework is a powerhouse crimeware kit that enterprises need to know about to better defend against it,” said Stuart Scholly, senior vice president and general manager, Security Business Unit, Akamai, in a statement. “It’s hard to detect, easy to use, and flexible – and it’s being used to breach enterprises across multiple industries.” A variant of Zeus, Gameover, was the subject […]

Report: Hell is Unpatched Systems

One of the ‘subplots’ of the Internet of Things revolution concerns embedded devices. Specifically: the tendency of embedded devices to be either loosely managed or – in some cases – unmanageable.   The future holds the promise of more, not fewer of these. That’s the gist of a piece I wrote for InfoWorld, and that you can read here. In short: we’re already seeing the beginning of a shift on the threat landscape. While attacks against traditional endpoints (like Windows desktops, laptops and servers) are still the norm, there are more stories each day about cyber criminal groups and malicious actors who are compromising non-standard endpoints like home wifi routers.  In March, for example, the security consultancy Team Cymru identified a botnet consisting of some 300,000 compromised home routers and other in-home devices. The virus called “TheMoon” was also identified spreading between vulnerable home routers and other embedded devices. The […]

Dan Geer Keynote: Security of Things Forum

The following is a transcript of a speech given by Dr. Dan Geer at the Security of Things Forum on May 7, 2014. The Forum was held at The Sheraton Commander in Cambridge, Massachusetts. The official copy of Dr. Geer’s speech lives on his web site, and can be found here. .Security of Things .Dan Geer, 7 May 14, Cambridge Thank you for your invitation and to the other speakers for their viewpoints and for the shared experience. With respect to this elephant, each of us is one of those twelve blind men. We are at the knee of the curve for deployment of a different model of computation. We’ve had two decades where, in round numbers, laboratories gave us twice the computing for constant dollars every 18 months, twice the disk drive storage capacity for constant dollars every 12 months, and twice the network speed for constant dollars every […]

Unknown Knowns: Arbor Warns Of Widespread Point of Sale Compromises

The hack of U.S. retailer Target put attacks on point of sale systems on the radar, and prompted major retailers to revisit the security of the systems that accept credit card transactions. Now research from Arbor Networks is warning that hackers and cyber criminals are doubling down on point of sale (PoS) systems with a wide range of specialized PoS malware and targeted attacks. Arbor says it has data suggesting that PoS compromises may be widespread, and undetected. Arbor’s Security Engineering & Response Team (SERT)  issued its findings in a Threat Intelligence Brief (2014-6)  report. The company said that “ambitious threat actors” are using targeted attack campaigns against PoS networks. The “longevity and extent” of PoS attack campaigns – even at wealthy and sophisticated organizations – is “a serious concern.”   [Read Security Ledger’s coverage of the Target data breach here.] “In organizations with security teams and well-managed network infrastructure, point of […]

Heartbleed: Technology Monoculture’s Second Act

Say ‘technology monoculture’ and most people (who don’t look at you cross-eyed or say ‘God bless you!’) will say “Microsoft” or “Windows” or “Microsoft Windows.” That makes sense. Windows still runs on more than 90% of all desktop systems, long after Redmond’s star is rumored to have dimmed next to that of Apple. Microsoft is the poster child for the dangers and benefits of a monoculture. Hardware makers and application developers have a single platform to write to – consumers have confidence that the software and hardware they buy will “just work” so long as they’re running some version of Windows. The downside, of course, is that the Windows monoculture has also been a boon to bad guys, who can tailor exploits to one operating system or associated application (Office, Internet Explorer) and be confident that 9 of 10 systems their malicious software encounters will at least be running some version of the […]
