Lessons learned from the Target PCI Breach

Posted by Steven Thom on Feb 15, 2014 1:51:31 PM

More information has been trickling out regarding the massive Target PCI breach that took place during the 2013 Christmas shopping season. Forensic researchers first learned that hackers penetrated Target's network by means of a business transaction portal. It appears that Fazio Mechanical Services was the source. Fazio is a Pittsburgh-area nationwide mechanical contractor that services many large retailers. Now more details are emerging about the mechanism hackers used to infect the HVAC contractor. There are serious lessons here that businesses of all sizes need to learn. It's safe to say the face of PCI compliance will forever be changed as a result of the findings.

179 Reasons to Upgrade Before January 2014

Posted by Steven Thom on Nov 15, 2013 1:06:06 PM

As of this writing there are roughly four useble business weeks left in the current year.  As 2013 winds down, businesses should consider performing needed upgrades sooner rather than later. At the risk of creating a lengthy blog post I'm planning to provide 179 reasons to upgrade before January 2014.

Goodbye Windows XP

Posted by Steven Thom on Jun 10, 2013 10:33:16 AM

It's nearly time to say goodbye Windows XP. This past April marked the one year count-down to the eventual discontinuation of support for the venerable operating system (technically on April 8, 2014). What does this mean to you? In short, it's high time you moved on and adopted Windows 7 or Windows 8.

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.

Apple blocks vulnerable Flash plugins

Posted by Steven Thom on Mar 4, 2013 8:30:08 AM

Kudos to Apple. Last week they decided to start blocking vulnerable versions of Adobe Flash plugins from running in the built-in Safari web browser. This is in direct response to the active exploits in the wild affecting Macs as well as PCs. Users who fail to update when prompted are now receiving an error message indicating the "Blocked Plugin" when they try to visit a website that invokes the Flash plugin. Apple did something similar when they blocked Java on February 1st, 2013 in response the the zero-day we reported here. The users receiving the error need to visit the Adobe website and manually install the update in order to continue viewing Flash content.

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.
