I have received the question “why should I migrate from NAC appliance to Identity Services Engine (ISE)?” a handful of times. This post will provide some reasons why you should consider migrating over. Regarding how to migrate and what discounts you could receive by migrating, see this post that covers these questions HERE.
There are many methods criminals will use to steal money that fall outside of normal attack channels. I was having dinner with a buddy from work and heard one of the most outrageous social engineering attack methods he recently experienced. To summarize, he had attackers call his home phone and try to get him to install malicious software. He figured out they were full of it yet went along with the scam for 20 minutes to see where they would take things. This post will cover his experience and variations of this attack seen in the wild.
Lesson learned …. don’t trust somebody just because they called you. Make sure to tell your friends and family this message. If you do some Google research, you will find many non-technical people are being tricked by this form of attack.Continue reading →
The people at howtogeek.com wrote a pretty funny yet sad post about research they performed. The concept is they went to download.com and downloaded the top 10 most popular downloads onto a virtual windows system to see what would happen (they skipped a few Anti Viruses since it doesn’t make sense to install more than one but outside of that went through the list). As shown in the previous screenshot, most of the software was laced with malware pretty much killing the functionality of their test system. The ironic thing is download.com has disclaimers on their website stating they don’t post software with malware, trojans or malicious adware before during or after the installation of software being shared (shown later in the post). According to the results from the howtogeek team, this is obviously not the case. I guess those old sayings are right about nothing is free and if its too good to be true … it probably is.

Andrea Allievi and Earl Carter posted a very interesting article on the Cisco security blog about a new version of Cryptowall. They talk about a very advanced threat capable of bypassing anti-malware and sandbox based defenses along with methods to hide communication to the control center using TOR channels. The original post can be found HERE.
Ransomware holds a user’s data hostage. The latest ransomware variants encrypt the user’s data, thus making it unusable until a ransom is paid to retrieve the decryption key. The latest Cryptowall 2.0, utilizes TOR to obfuscate the command and control channel. Continue reading →
Norse is a research group that leverages hundreds of honey pots placed all over the world to collect attack data. Their claim to fame is their research goes beyond the general internet targeting “dark intelligence” meaning parts of the darknet where the bad actors live. They offer a few products that can be placed on your network as well as SAS services that work with their threat intelligence to identify attacks against your network. You can find their main website HERE.
One cool free online tool they offer is a live mapping of attack data. That data can be found at http://map.ipviking.com/ or HERE. Below is a screenshot of this tool. Its a pretty cool concept. Check it out Continue reading →
My buddy Aamir Lakhani from dcchaos.com put together a list of the best cyber security talks of 2014. The rankings and opinions are purely his own.
