Electronic Pickpocketing – Check Your Credit Card

RDIFChannel 13 hosted a short segment on the risk of using RFID enabled credit and debit cards. RFID means the card broadcasts the sensitive information over radio frequency so the consumer just has to swipe the card near a reader to buy something. With this convenience comes the risk of a malicious party using a wireless sniffer to capture the same data. This means the malicious party can pick your pocket without having to touch the card IE they can capture the credit card data over the radio and print their own card. In the video, the presenter copies a capture credit card to his hotel room key and makes a purchase using room key with the stolen data as if it was the original credit card. It is pretty easy to do.

How To Prevent And Remove Ransomware

ransomeware200Comparitech.com wrote a helpful post about Ransomeware. This continues to be a hot security topic hitting many of my customers. For those that don’t know, Ransomware is malware that encrypts your files and holds them for ransome requiring a bitcoin payment to unlock them. The original post can be found HERE.

While ransomware has existed since around 1989, in the form of the “AIDS” trojan which encrypted files on a hard drive and then demanded a payment of $189 to unlock them again, it is only in the last few years that it has become a significant and global threat. Continue reading

Tax Time: Let the Phishing Begin

phishingcartoonEarl Carter and Craig Williams from the Cisco Security Blog posted a great article on a recent wave of taxed related spear-phishing attacks (original post found HERE). What is interesting is how attackers leverage current trends as the theme for their malware. For example, we will probably see a bunch of March Madness attacks along with Tax related phishing this month since thats what people are searching for online. This contradictions the old belief that “safe searching” aka not going to adult websites or searching for free software will keep you safe from malware. The reality is the attackers want the most bang for their buck so they will target where the most people are at. In March, thats Tax season and March Madness. Here is the post from Cisco.
