Sources on a number of forums tell me that a certain application is going to be released into the wild in a few days, promoted heavily via sites such as Youtube to attract as many potential victims as possible. I thought it might be beneficial to get a head start on the bad guys and get word out before they hit their big green “Go” switch. What is it? I believe the following screenshot can answer that question: ...
We frequently read stories about spammers who can circumvent CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) authentication. Using bot-infected machines, they can create a vast number of random e-mail accounts for spamming purposes. This week, a federal judge in Newark, New Jersey, revealed the latest use of a botnet-like network with a CAPTCHA breaker. In this case, the computers overseen by the defendants were used to buy seats for high-profile concerts and sports events from ticket sellers’ websites. The defendents later allegedly resold the tickets on Internet at much higher prices. ...
On Friday evening I was talking to a North American customer who had been fighting with infections caused by SEO poisoning. They mentioned a particular search term that could generate new samples of FakeAVs. The funny thing was that the website hacked by the SEO poisoner was a blog of someone trying to promote legitimate business use of SEO technologies.. If you click on any of the links returned by the search you would be redirected to an Indian site containing this image: ...
We all know Brazilian hackers have mastered the art of creating banking trojans. The Chinese are very fond of password stealers targeting online games. The bad guys do have preferences for what type of malware they are creating based on their geolocation. Well, I found this exploit source code from a domain named kuwait{removed}.com The exploit downloads a file named unek.exe, very well known to be an IRC bot. ...
Somebody is trying to pose as F-Secure. If you see an email like the one below, just ignore it: Before you ask: No, we’ve never heard of “F-Secure HTK4S anti-virus” either.
Recently, We received some malicious files which appeared to be signed by “Adobe Systems Incorporated”. On closer inspection, however, it was seen that the signature was just a ruse used by the malware author to give an air of legitimacy to the files. Virus writers are getting smarter and going that extra mile to digitally sign their files. Using this technique the malware authors could, for example, penetrate an environment where only signed files are allowed but the authenticity of the signature is not checked. ...
Just when we thought SEO using Flash was as interesting as SEO poisoning can get, it seems it’s getting even sneakier… Imagine a PDF file posted by someone evil online. Of course, Google being Google, the file is recognized as a PDF. And when we open it, it really is a PDF. No evil codes inside, just a good old vanilla PDF file. Three hours later… Google still says the file is a PDF. Brod (one of our geeky guys here) is attributing this to Google’s cache. ...
Microsoft has issued an advance notification for Patch Tuesday next week. The company said it expects to issue two patches, one for Windows and one for Office. Both are intended to patch vulnerabilities that could allow remote code execution and both are rated “important.” Microsoft Security Bulletin Advance Notification for March 2010 here.
This morning while I was enjoying my coffee I received an event notification for my personal Facebook account. It was for a group called “See Who’s Spying On Your Profile – GET NOTIFIED -”. and “See Everyone Who Views Your Profile”. Immediately, my security hat went on and I started to investigate. At first glace, they are both pyramid schemes. In both, you become a fan, then you have to suggest the page to 50 of your friends to move onto the next stage. From there the tactics diverge slightly. In the first one, you need to take a marketing quiz that asks for all sorts of personal info, and you need to put in your Facebook username and password, so they can “monitor” your profile. AND you have to provide them with your mobile number. Now wait a minute… why would they need my mobile number? ...
As we have commented before when content served up from adservers is compromised, the effects can be far reaching, potentially exposing huge numbers of victims to the malicious code as they innocently browse legitimate sites. The problem is further complicated by the fact that legitimate ad content is often heavily obfuscated, in order to evade ad-blocking technology. During the latter half of this week we have seen a whole batch of compromised adservers injected with malicious JavaScript to silently load malicious content from a remote site. A significant number of popular sites that load ads content from these servers have therefore been affected by this attack. ...
