Published: March 1, 2010 Reading time: 2 min

If history is any gauge, this is probably the first of several incidents like this. The Register – which is worth reading twice a day for its insanely funny headlines if nothing else – is reporting that a hacker (hacktivist?), possibly British, who goes by the handle Neo, has gotten his hands on tax documents for about 1,000 companies and is tweeting the salaries of Latvian bank managers and other execs to Latvian TV. ...

Insight into fake AV SEO

Published: February 26, 2010 Reading time: 2 min

In this post I want to highlight how SEO attacks are working: Pages using server side kits to fool search engine bots into ranking them high in results are uploaded to legitimate web sites. If all goes to plan, when a user searches for a popular term, high up in the search engine results are links to these pages. In the example below, the malicious SEO page was the 2nd item in the search results (highlighted in blue). When the user arrives on such a page (highlighted in green in the example below), the referrer is typically checked to ensure they came from a search engine. If so, there are redirected (302 redirect) to another site (orange below). There are typically additional levels of redirection from this point. In the example shown below, the user is bounced from the .org to the .in site (purple). Finally, the user will be redirected to the fake AV distribution site (red). This is where the user receives the usual visual trickery, in order to fool them into installing the rogue application. ...

A survey of 54,000 households (129,000 people) commissioned by National Telecommunications and Information Administration (NTIA) last year found that 30 percent of U.S residents did not use the Internet at home or at work.

Symantec Reputation-based Security: Suspicious.Insight detections on VirusTotal

Published: February 21, 2010 Reading time: 4 min

Symantec recently upgraded their scanner on VirusTotal to include their new reputation-based security engine. That has caused a spike in their detection rates, in particular Suspicious.Insight detections, and so I thought I’d take a few minutes to explain some of the background and what is going on. So what exactly is a Suspicious.Insight detection? These detections are derived from Symantec’s new reputation-based security technology. They highlight files that have not yet developed a strong reputation (either good or bad) amongst Symantec’s community of users. their goal is to keep their users’ machines safe, and part of achieving that goal means helping their users make informed choices about the files they allow on to their systems. Suspicious.Insight detections help shine a spotlight on files that have not yet developed a full reputation. ...

Peter Coogan at Symantec put up a very interesting blog post yesterday about a crimeware kit called SpyEye v1.0.7 (on sale now on Russian sites — $500) that has a module that will kill a Zeus bot infection on a victim’s computer so the bot created by SpyEye can take it over. In September, Computer Weekly reported the Swedish telco Telia Sonera shut down the Internet connections of Latvian company Real Host after it was linked to the Zeus botnet. At the time, researchers said they believed Real Host’s servers had captured about 3.6 million PCs for the Zeus botnet. ...

Phony Firefox update comes with Hotbar adware

Published: February 7, 2010 Reading time: 2 min

Our good friends at Broomfield, Colo., security firm eSoft have found an interesting scam to trick Internet users into installing the Hotbar adware: a fake Firefox download site. The eSoft researchers are theorizing that an affiliate of Pinball Publisher Network (PPB). is responsible. Pinball bought the Zango assets after that pestilent operation failed last spring. However Sunbelt Software Spyware Research Manager Eric Howes did some more digging and found that PPN offers the download file on a site they own so affiliates can send customers victims there for downloads. ...

Hackers Disrupt European CO₂ Market

Published: February 2, 2010 Reading time: 2 min

In recent weeks, various cybercrime attacks have disrupted the computer systems that allow nations to manage their national greenhouse-gas emissions quotas and their possession of carbon assets according to international agreements (the Kyoto Protocol and the European system).

Published: January 25, 2010 Reading time: 2 min

Ben Edelman, Harvard privacy researcher and guru has revisited the features of Google Toolbar and was appalled to discover that disabling it doesn’t really disable it. He is recommending that all users uninstall it. In a long, thorough and well-written piece on his blog Edelman discusses how he monitored the Toolbar’s behavior with a network sniffer and documented the transmission of data back to Google (to toolbarqueries.google.com). Not only does it track a user’s Google searches, but it also phones home information about searches done in other search engines. ...
