Crimevertising: Selling Into the Malware Channel

February 8, 2012

Anyone who’s run a Web site is probably familiar with the term “malvertising,” which occurs when crooks hide exploits and malware inside of legitimate-looking ads that are submitted to major online advertising networks. But there’s a relatively new form of malware-based advertising that’s gaining ground — I’m calling it “crimevertising” for lack of a better term — that involves running otherwise harmless ads for illicit services inside of commercial crimeware kits.

At its most basic, crimevertising has been around for many years, in the form of banner ads on underground forums that hawk everything from hacking services to banking Trojans and crooked cashout services. More recently, malware authors have started offering the ability to place paid ads in the administrative panesl that customers use to control their botnets. Such placements allow miscreants an unprecedented opportunity to keep their brand name in front of the eyeballs of their target audience, and for hours on end.

Half of Fortune 500s, US Govt. Still Infected with DNSChanger Trojan

February 2, 2012

More than two months after authorities shut down a massive Internet traffic hijacking scheme, the malicious software that powered the criminal network is still running on computers at half of the Fortune 500 companies, and on PCs at nearly 50 percent of all federal government agencies, new research shows.

The malware, known as the “DNSChanger Trojan,” quietly alters the host computer’s Internet settings to hijack search results and to block victims from visiting security sites that might help scrub the infections. DNSChanger frequently was bundled with other types of malware, meaning that systems infected with the Trojan often also host other, more nefarious digital parasites.

‘Citadel’ Trojan Touts Trouble-Ticket System

January 23, 2012

Underground hacker forums are full of complaints from users angry that a developer of some popular banking Trojan or bot program has stopped supporting his product, stranding buyers with buggy botnets. Now, the proprietors of a new ZeuS Trojan variant are marketing their malware as the first offering that lets customers file bug reports, suggest and vote on new features in upcoming versions, and track trouble tickets that can be worked on by the developers and fellow users alike.

Amnesty International Site Serving Java Exploit

December 22, 2011

Amnesty International’s homepage in the United Kingdom is hacked and is currently serving malware that exploits a recently-patched vulnerability in Java. Security experts say the attack may be opportunistic, or it may be part of a more nefarious scheme to target human rights workers.

Download.com Bundling Toolbars, Trojans?

December 6, 2011

It wasn’t long ago that I felt comfortable recommending CNET’s download.com as a reputable and trustworthy place to download software. I’m going to have to take back that advice: Unfortunately, CNET now is bundling invasive and annoying toolbars with much of the software on its site, even some open-source software whose distribution license prohibits such activity.

I first became aware of this after reading mailing list posting by Gordon “Fyodor” Lyon, the software developer behind the ever useful Nmap network security scanner. Lyon is upset because download.com, which has long hosted his free software for download, recently began distributing Nmap and many other titles with a “download installer,” that bundles titles with browser toolbars like the Babylon toolbar.

Apple Took 3+ Years to Fix FinFisher Trojan Hole

November 23, 2011

The Wall Street Journal this week ran an excellent series on government surveillance tools in the digital age. One story looked at FinFisher, a remote spying Trojan that was marketed to the governments of Egypt, Germany and other nations to permit surreptitious surveillance for law enforcement officials. The piece noted that FinFisher’s creators advertised the ability to deploy the Trojan disguised as an update for Apple’s iTunes media player, and that Apple last month fixed the vulnerability that the Trojan leveraged.

But the WSJ series and other media coverage of the story have overlooked one small but crucial detail: A prominent security researcher warned Apple about this dangerous vulnerability in mid-2008, yet the company waited more than 1,200 days to fix the flaw.

DHS Blasts Reports of Illinois Water Station Hack

November 22, 2011

The U.S. Department of Homeland Security today took aim at widespread media reports about a hacking incident that led to an equipment failure at a water system in Illinois, noting there was scant evidence to support any of the key details in those stories — including involvement by Russian hackers or that the outage at the facility was the result of a cyber incident.

Last week, portions of a report titled “Public Water District Cyber Intrusion” assembled by an Illinois terrorism early warning center were published online. Media outlets quickly picked up on the described incident, calling it the “first successful target of a cyber attack on a computer of a public utility.” But in an email dispatch sent to state, local and industry officials late today, DHS’s Industrial Control Systems Cyber Emergency Response Team (ICS-CERT) said that after detailed analysis, DHS and the FBI have found no evidence of a cyber intrusion into the SCADA system of the Curran-Gardner Public Water District in Springfield, Illinois.

‘Biggest Cybercriminal Takedown in History’

November 9, 2011

The proprietors of shadowy online businesses that have become synonymous with cybercrime in recent years were arrested in their native Estonia on Tuesday and charged with running a sophisticated click fraud scheme that infected with malware more than four million computers in over 100 countries — including an estimated 500,000 PCs in the United States. The law enforcement action was the result of a multi-year investigation, and is being called the “biggest cybercriminal takedown in history.”

Are You on the Pwnedlist?

November 2, 2011

2011 has been called the year of the data breach, with hacker groups publishing troves of stolen data online almost daily. Now a new site called pwnedlist.com lets users check to see if their email address or username and associated information may have been compromised.

Pwnedlist.com is the creation of Alen Puzic and Jasiel Spelman, two security researchers from DVLabs, a division of HP/TippingPoint. Enter a username or email address into the site’s search box, and it will check to see if the information was found in any of these recent public data dumps.
