Trendjacking threats are a growing concern

Posted by Steven Thom on Aug 9, 2013 5:20:25 PM

I'm sure you've seen this, and I hope you haven't fallen for it. Nevertheless, it must work because the bad guys keep doing it. The term is "Trendjacking", and it refers to spammers and malware authors using current trends to trick you into opening malicious email messages.

Oracle closes critical Java vulnerability

Posted by Steven Thom on Mar 5, 2013 7:55:43 AM

Oracle announced today the release of updates for Java versions 5, 6, and 7 to patch a critical java vulnerability actively being exploiting in the wild. The patches were reportedly slated for release in April but the timetable was pushed up in response to a recent report demonstrating the active exploit. This further prolongs the life of Java 6, which was slated for retirement last month but continues to receive updates in the wake of a continual barrage of zero-day exploits.

Yet Another Java Zero-Day

Posted by Steven Thom on Mar 3, 2013 12:09:38 AM

Researchers at the respected security firm FireEye have discovered yet another Java zero-day attack that leverages previously unknown vulnerabilities with the latest versions of Java (as of this writing Java v1.6 Update 41 and Java v1.7 Update 15) to install malware. This comes on the heels of a discovery of two other holes (as yet unexploited) by the Polish firm Security Explorations this past week.

Why did I get a virus?!

Posted by Steven Thom on Jan 15, 2013 1:48:54 PM

For crying out loud... How did this happen? You're just surfing along, minding your own business and BAM - some bogus-looking thing pops up claiming you have 300 infected files and you need to pay $70 to get your computer cleaned. Or, like my elderly neighbor over the past weekend, you get a scary full-screen warning informing you that you'll be prosecuted for copyright infringement. Here's what that looked like...

Are you using Postini? It's time to make other plans

Posted by Steven Thom on Jan 15, 2013 1:00:09 AM

Are you a Postini user? Postini is an email security platform that was gobbled up by Google a few years ago. Google Apps email users have enjoyed the spam and virus protection ever since, as have many clients who leveraged the Postini tools to cleanse their incoming email before it arrived on their own servers. The first group is in luck - they'll continue to use Postini. The second group, however, will have to look elsewhere for this type of filtering. Naturally, Google would like to have all of them migrate their business email to Google Apps (not a bad choice) but this just isn't feasible for many.

Posted by Steven Thom on Dec 10, 2012 8:21:06 PM

Oracle has announced that the end-of-life (EOL) of Java SE 6 has been moved from November 2012 to February 2013. This is to give organizations small and large more time to transition to Java SE 7.

The last publicly available release of Java SE 6 will be in February 2013 with the release of Java SE 6u37.
