Adobe and Microsoft release critical patches for March

Adobe and Microsoft have both released patches this week to address vulnerabilities in respective software applications and advise all users to apply the patches as soon as possible, if applicable to them.

Anatomy of a Biting Bunny – The Infected Microsoft Catalog Update

Aryeh Goretsky posted a blog about a trojan program in a Microsoft catalog update. I thought it might be a little interesting to know how this can happen and why it doesn’t happen more often. As it turns out, it was once my job to make sure that Microsoft did not release infected software. Initially

MS10-092 and Stuxnet

…among the 17 security bulletins just released by Microsoft on Patch Tuesday, MS10-092 addresses the Task Scheduler vulnerability prominently exploited by Win32/Stuxnet…

Patchwork for the Home and the Enterprise

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

Adobe, Javascript, and the CVE-2009-4324 Exploit

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. The following Adobe articles refer: http://www.adobe.com/support/security/advisories/apsa09-07.html http://blogs.adobe.com/psirt/2009/12/new_adobe_reader_and_acrobat_v.html http://blogs.adobe.com/psirt/2009/12/security_advisory_apsa09-07_up.html Today's article at the Internet Storm Center by Bojan Zdrnja (http://isc.sans.org/diary.html?storyid=7867) gives a lot of detail on a particularly inventive exploit of the

Ten Ways to Dodge Cyber-Bullets (Part 2)

[Part 2 of an occasional series, updating a blog series I ran in early 2009 to reflect changes in the threat landscape. 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

September’s Global Threat Report

ESET released its Global Threat Report for the month of September, 2009, identifying the top ten threats seen during the month by ESET's ThreatSense.Net™ cloud.  You can view the report here and, as always, the complete collection is available here in the Threat Trends section of our web site.  While the report identifies a number

Adobe Updates

I’d like to call your attention (again) to a major Adobe bulletin that was released yesterday (actually, still today, if you’re far enough behind GMT, but I’m sitting just a train ride away from Greenwich, UK). In brief, the bulletin concerns the following CVE (Common Vulnerabilities and Exposures) issues: CVE-2009-1862 CVE-2009-0901 CVE-2009-2395 CVE-2009-2493 CVE-2009-1863 CVE-2009-1864 CVE-2009-1865

Statistical Accuracy and the Gullibility Gene

SC Magazine in the UK picked up on our Global Threat Report for June, based on statistics that derive from our ThreatSense.Net® threat-monitoring technology. Thanks, Dan: when you do as much writing as I do, it’s comforting to know that someone is reading it. ;-) I thought, though, I’d develop some thoughts on a topic arising

Signed Updates and Social Engineering

Someone raised an interesting point in a comment to yesterday’s blog about Symantec’s own PIFTS.EXE being flagged by their own firewall as a possible problem. Let me quote the comment in full. I by no means buy into the super root-kit routine, I do however think that there will be copy cats (if not already)

Acrobat Amendment

A reminder about about the Acrobat reader vulnerability we blogged about several times recently (http://www.eset.com/threat-center/blog/?p=593, http://www.eset.com/threat-center/blog/?p=579, http://www.eset.com/threat-center/blog/?p=572). Remember I said "As we’ve said previously, disabling JavaScript, while it doesn’t address the underlying vulnerability, stops known exploits from working properly"? Predictably, there are now known exploits that don’t use the JavaScript heap spray trick. While I’m

The Perils of PDF

Security issues with PDFs are nothing new, as a skim through past Adobe security bulletins and advisories indicates. (This isn’t a criticisim of Adobe: it’s inevitable that security issues will surface from time to time in sophisticated, function-rich software, and Adobe are clearly aware of the need to address the problems as they arise.) In

MS09-002 Exploits: Old Dogs, New Tricks?

A few days ago, I promised (threatened) to make some general points about biasing test results, but travel and other obligations have been getting in the way. I’ll get back to that very shortly, but in the meantime, I want to look at an issue with the latest round of Microsoft patches that I was

Confounding Conficker

[Update: Spiegl Online reports (in German!) that the total may be as high as 50 million infected machines: however, this figure seems to be extrapolated from the number of infections picked up Panda's online scanner. Statistically, I'm not sure it makes any sense at all to try to correlate this self-selecting sample to the total population of
