Simply throwing more staff at the patching problem won’t cut it, a study suggests.
How do patches work? Could the Microsoft patch have stopped WannaCryptor? All your questions answered.
[UPDATE #1: (21 Dec 2012, 5:30PM) ESET Researcher Cameron Camp has just published the second part of this series on securing your Android device. Read it here on the ESET Threat Blog at Securing Your Holiday Tech Gifts, Part 2: Android Guide. AG] December is upon us, and whether you have a Christmas tree, menorah,
On Thursday, September 12, Duo Security, a young-but-respected vendor of two-factor authentication devices, announced the preliminary results of a study of over 20,000 Android devices from a two month old study they performed. Based on the results, they calculated that over half of Android devices on the market have security vulnerabilities that are, as yet,
If you are a Mac user and you have Java installed on your Mac, then right now would be a good time to run Software Update… from the Apple menu to make sure you have installed the latest Java for Mac OS X update. Installing this update will help protect your Mac from a malicious
Introduction Mobile World Congress 2012 is almost upon us, and one of the most hotly-anticipated topics is the next generation of Microsoft’s smartphone operating system Windows Phone 8, which has been kept under wraps far more tightly than its PC counterpart, Windows 8. While Microsoft was an early adopter in the creation of smartphones with
The two most prevalent threats over 2011 were still INF/Autorun and Conficker: ESET's December ThreatSense Report looks at threat trends in the new year.
Nearly three years old, the Conficker worm continues to pose a threat to PCs. Aryeh Goretsky wants to know why this is, and what can be done about it.
It's something of a truism, that 'old viruses never die', and that certainly seems to be the case for some of the older, more widespread, email worms. In this interview (http://www.signonsandiego.com/uniontrib/20041129/news_lz1b29five.html) back in 2004, I talked about an email worm called "Win32/Zafi.b" which, at the time, had recently been spreading on a global scale. However,
My colleagues in Hungary have released some slightly alarming statistics about malware awareness in their part of the world. Research carried out on their behalf by NRC suggests that a significant proportion of Hungarian Internet users don't even know what AV software is installed on their computer (or, presumably, if anything is installed.) http://www.eset.hu/hirek/holgyek-tessek-vedekezni?back=%2Fhirek Out
Our colleagues Aleksandr Matrosov and Eugene Rodionov are tracking the evolution of TDL4 (also known as Win32/Olmarik). The following is a report on the latest TDL4 update, released last week. In our previous blog post, we described how the latest Microsoft Security Update modified the Windows OS loader (winloader.exe) to fix a vulnerability that allowed
The security update won’t necessarily help users who have already been infected with the bootkit as TDL4 blocks the Windows Update service on x86 machines. As a result, infected x86 machines won’t be able to download and install the patch automatically.
UPDATE #1 Randy Abrams has posted a follow-up article, Anatomy of a Biting Bunny – The Infected Microsoft Catalog Update with additional information about how update services work, why they might distribute third-party code and what might be done to prevent malware from being distributed on services like Microsoft’s Windows Update in the future. 7-FEB-2011.
As expected, Microsoft has released a critical out-of-band patch for the LNK shortcut file vulnerability which received attention last month. As a critical patch, this update will be delivered through Windows’ Automatic Update service, as well as being directly available for download from Microsoft’s site without a Windows Genuine Advantage check. A reboot is required for the
On July 17th, ESET identified a new malicious file related to the Win32/Stuxnet worm. This new driver is a significant discovery because the file was signed with a certificate from a company called "JMicron Technology Corp". This is different from the previous drivers which were signed with the certificate from Realtek Semiconductor Corp. It is
SC Magazine's Dan Raywood reports that "To be completely patched requires an average of between 51 and 86 actions per year", quoting findings by Secunia that " in order for the typical home user to stay fully patched, an average of 75 patches from 22 different vendors need to be installed, requiring the user to
There is a vulnerability in Internet Explorer that Microsoft will patch tomorrow. Normally Microsoft releases patches on the second Tuesday of each month, but in the case Microsoft is making the patch available much sooner. The most probable reason for the “out of band” patch is that this vulnerability received a ton of attention as
There has been quite a lot of traffic in the last few weeks about the doc.media.newPlayer vulnerability referenced in the CVE database as CVE-2009-4324.

This series will also be available shortly as a white paper.] Catch the Patch Batch Keep applications and operating system components up-to-date with automated updates and patches, and by regularly reviewing the vendors’ product
I recently received a question at email@example.com that I think maybe of interest to more than just the author. I read an interesting article written by Kaspersky Lab titled "Drive-by Downloads. The Web Under Siege" and have a question I was hoping you could answer. (I have included a link to the article below.) Are
