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.

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.

Posted by Steven Thom on Feb 18, 2013 12:13:47 PM

Facebook has confirmed that they were a victim of a targeted attack that leveraged a previously unknown Java vulnerability. The zero-day exploit was used to infect the laptops of several engineers with malware that apparently was used to attempt a full-scale infiltration of the inner sanctum of Facebook.

New Adobe Acrobat Zero-Day Reported

Posted by Steven Thom on Feb 13, 2013 12:13:16 PM

Researchers from the respected malware research firm FireEye today reported a zero-day flaw that is actively being exploited in the wild. They reportedly observed successful exploitation of the latest Adobe PDF Reader 9.5.3, 10.1.5, and 11.0.1. It is assumed that earlier versions are also vulnerable though this has not been confirmed.

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...

Facebook to begin using HTTPS

Posted by Steven Thom on Nov 21, 2012 3:57:54 PM

As announced last year, Facebook is moving to HTTPS for all users. "This week, we're starting to roll out HTTPS for all North America users and will be soon rolling out to the rest of the world". This should result in safer Facebooking from hotspots and coffee shops, which have been targets of so-called man in the middle attacks, whereby hackers intercept unencrytped logons via bogus wireless hotspots.
