This little thing knows your credit card number and doesn’t need the pin to empty it

The researcher Samy Kamkar caused a really mess this time: he discovered that using a credit card it was possible to guess the number of the new credit card sent to their owners by the banks when the actual expires or is stolen. He combined this knowledge with the possibility of shopping without entering the correct PIN and he created an infernal device on sale for 10 $. If after that shock somebody can keep reading us, we will talk about why Yahoo doesn’t like adblockers, how Facebook warned to government employees that they had been hacked and our reader will join us in the reflection on the called “cyberterrorism” and if it is a real menace.

Samy Kamkar warned to American Express about his amazing discovering but the entity didn’t pay attention because, although the device predict the number of our future credit card, it can’t do the same with the 4 control digits, removing the possibility of shopping in stores where this is asked as a security measure. Not idle, Kamkar decided to show them the danger is real, building a device to emulate credit cards allowing to shop in stores or restaurants, without entering the PIN. Now American Express pays attention and they assures they will solve the issue soon.

Yahoo doesn’t want adblockers 
Moving on another subject: The adblockers war. These programs used for blocking ads in our web surfing are increasingly used, putting in danger the viability of the websites living of these ads. Yahoo has decided to face the problem and force to users to deactivate the adblocker if they want read their e-mail using Yahoo´s service, which is free in exchange for showing ads to their users, in addition of collecting all the possible personal data.

Facebook is your father 
By the way these services maybe already know to much about us, although it could be useful sometimes. A good example is a group of public employees of the State Department of the USA, whose accounts were hacked the past month by supposed Iranian mercenaries. Nobody warned them until they received this message: “We think your Facebook account and other web accounts could be the target of attacks of actors sponsored by a State”. True or false? Anonymous sources of the governments had confirmed it to the press.

Is cyberterrorism real? 
We finish with a text to think about the “cyberterrorism” and the “cyberwar”. From the announce of the Britain chancellor George Osborne about an important increase (the double) in the budget dedicated to national cybersecurity in this country, the author ponders about the veracity of the arguments exposed to explain this cost, being one of the main arguments the defense of critical infrastructures in an scenario in which they have not suffered any hacker attacks yet, but many coming from birds and squirrels.
