Win32/Quervar (a.k.a Dorifel, XDocCrypt) is a virus family that has been in the news recently, especially in the Netherlands. It has been reported to be causing havoc on computers of several notable Dutch institutions. In our analysis, we provide additional technical details about the workings of the virus and compare it to another virus, the
A crime wave of malware that demands money from victims to avoid prosecution by the FBI has been alarming web surfers across America. Victims suddenly find their computer frozen, and an official-looking page, like the one shown below, is displayed in their web browser. The FBI and the Internet Crime Complaint Center (IC3) have received
Last week, reports of a new malware named Gauss emerged, a complex threat that has attracted a lot of media attention due to its links to Stuxnet and Flame and its geographical distribution. Since ESET has added detection for this threat, we are seeing geographical distribution of detection reports similar to those detailed by Kaspersky.
Win32/Gataka is an information-stealing banking Trojan that can read all of your web traffic and alter the balance displayed on your online banking page to hide fraudulent transfers. It exhibits a modular architecture similar to that of SpyEye, where plugins are required to achieve most of the malware functionality. In our previous blog post, we
Sharing details of the hack that “wiped his life” has earned Mat Honan a place in the annals of information system security; the specific inter-dependence of flawed authentication systems that cost him so dearly–encompassing Apple, iCloud, Amazon.com, Gmail and more–would probably still exist if Mat had not gone public. Wired has the full story here
Part of my daily routine here at ESET is to inspect URLs for new trends and malware campaigns identified by our systems. A couple of weeks ago I noticed a group of URLs with a similar pattern. When I investigated further, I found out that the URLs pointed to copies of legitimate web sites with
For years scammers and hackers focused largely on Windows x86-based platforms, in many ways because that’s where the bulk of the users were. But times change, and new targets emerge. At Blackhat and Defcon last week we saw a flurry of talks on Mac OSX/iOS security, trying to illuminate possible chinks in the armor. From
After my colleague Stephen Cobb stood in a huge line at Defcon waiting to get into the Friday keynote by NSA chief General Alexander, plus a swarm of interest shown at the two-part Meet the Fed panel presentation the next day, it’s becoming clear that multiple agencies of the federal government are focused on hackers,
If your organization’s website runs on Apache, and many do, you might wonder if the webserver’s .htaccess controls are securely configured. If you believe the demo we saw yesterday at Blackhat by Matias Katz and Maximiliano Soler, the answer is a resounding ‘NO!’ What Katz and Soler described in their session is not some rare
Blackhat keynote speaker Shawn Henry, the former executive assistant director of the FBI’s Criminal, Cyber, Response and Service Branch, started off the day after opening remarks from Jeff Moss, founder of Blackhat. Moss wondered if now was the time for the cyber-security sector to take a more aggressive/offensive approach. Jeff mentioned working for a former
Want to access the music tracks of YouTube.com videos on your iPod but don’t want to pay? You’re not alone. Recently, a crop of websites have popped up offering to convert the audio from videos to .mp3 files that you can then download at no charge. Sounds great, right? The catch: scammers are trying to
Changing the passwords on your online accounts might not sound like a fun weekend activity, but that’s what I did last weekend. Why? Because on Sunday I found out that one of my email addresses was in the list of Yahoo! logins whose passwords were exposed by sloppy handling of a credential file (an incident
There are always people who want to piggy-back on the achievements of others. After ESET warned the public against ACAD/Medre.A in two blogs here and here and issued a free standalone cleaner for remediation, there was always the possibility that drawing attention to the issue would result in the topic being misused for other purposes.
Are you one of the 50 million users of Instagram, the photo-sharing service bought by Facebook in April for $1 billion? If so you need to look out for an Instagram update to fix a vulnerability that has just been published by Spanish security researcher Sebastián Guerrero. This vulnerability, which Guerrero has dubbed the "Friendship
Evidence that criminals are targeting the computer systems of small businesses continues to mount. The Wall Street Journal recently drew attention to the way cybercriminals are sniffing out vulnerable firms. The article highlighted the fact that about 72% of the 855 data breaches world-wide last year that were analyzed in Verizon's Data Breach Investigation Report
It’s here, folks! If the replaced DNSChanger servers don’t get another deadline extension, more than 500,000* computers may not be able to reach their configured DNS service after next Monday, July 9, 2012. In other words, it will be practically impossible for the users of those computers to surf the Internet using human friendly domain
David Harley describes a support scam that uses a slightly different twist, misrepresenting the output from Windows Task Manager.
Following the flurry of press coverage surrounding the proposed next generation of driverless cars, privacy groups are asking questions about what will happen to the data the cars (necessarily) collect, which – in the wrong hands – might prove tempting for abuse. Other car manufacturers plan on rolling out real-time data streams of information about
For the story behind the suspected industrial espionage, where ACAD/Medre.A was used, refer to Righard Zwienenberg's blog post. For technical details from analysing the worm's source code, read on. ACAD/Medre.A is a worm written in AutoLISP, a dialect of the LISP programming language used in AutoCAD. Whilst we classify it as a worm, due to
The malware news today is all about new targeted, high-tech, military grade malicious code such as Stuxnet, Duqu and Flamer that have grabbed headlines. So imagine our surprise when an AutoCAD worm, written in AutoLISP, the scripting language that AutoCAD uses, suddenly showed a big spike in one country on ESET’s LiveGrid® two months ago,
