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.

Anti-virus software alone is not enough

Posted by Steven Thom on Mar 4, 2013 1:17:18 PM

"Anti-virus software alone is not enough"... so says the number one antivirus provider Symantec in this post. A rather stunning admission I would say, and something many in the computer and network security industry have known for quite some time.

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.

Apple also a victim of targeted malware attack

Posted by Steven Thom on Feb 19, 2013 10:38:33 AM

Apple revealed today that they were targeted by the same malware attack leveled against Facebook on February 1st. The earlier comments by Facebook hinted at a working group of high-value targets and Apple now appears to be among them. The attack took advantage of a previously unknown Java zero-day exploit to infect the engineers' computers by means of their web browsers.

Adobe has scheduled an update for last week's Acrobat zero-day

Posted by Steven Thom on Feb 18, 2013 1:13:06 PM

Adobe announced in a blog post that they will issue updates for version XI, X, and 9 to close the zero-day hole revealed last week. The patch will be released for Windows, Linux, and Macintosh operating systems. All users are advised to install the patch as soon as it becomes available. Thom Infotech encourages Adobe Acrobat users to enable the automatic update feature that both downloads and installs the patch as soon as it becomes available. This can be found in the Edit > Preferences menu. Scroll down to the "Updater" section and change the default ("Automatically download updates, but let me choose when to install them") to "Automatically install updates". Our Managed IT Services clients will receive the update automatically.

Facebook has confirmed that they were a victim of a targeted attack that leveraged a previously unknown Java vulnerability.

Oracle releases emergency patches for Java

Posted by Steven Thom on Feb 2, 2013 7:51:16 AM

Oracle has released a sizable number of patches for Java to address 50 vulnerabilities affecting both the browser versions as well as the server. The "Critical Patch Update February 2013" (CPU) for Java had been scheduled for February 19th, but due to one of the vulnerabilities being exploited in the wild, the company brought the release forward. Oracle advises users to install the update as soon as possible because of "the threat posed by a successful attack". This may explain the sudden move by Apple to disable Java in the browser yesterday (February 1 2013).

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...

Microsoft releases out-of-band patch for the IE8 (and below) zero-day hole

Posted by Steven Thom on Jan 13, 2013 8:15:37 PM

Microsoft has released a rare out-of-band critical update that appears to address the zero-day exploit announced on January 5th. The software giant previously released a manual "fixit" for this vulnerability but researchers soon found ways around the patch. This update addresses the original problem and is slated for release on January 14th, 2013
