Jacob Appelbaum, hacker, former Wikileaks volunteer recently told not to register on Facebook if you do not wish surveillance organized on you. He admitted, you will give out sensitive information even without your consent - if you have even a couple of friends who may tag you on pictures.

To be even more precise, even if you do NOT register, you might be tagged - but that is just another part of story.

Also Jacob says, Facebook is the greatest database of Jews, leftists, right wing people and anyone else in the world, who may be targeted one day after the governmental change.

There still is one way to use it through IP substitution tools like TOR and inserting false data, having false friends, making information other ways useless. But is this the reason millions of people use it so much?

Facebook has revealed a security system called FIS (Facebook Immunity System). FIS controls every read-write action of each user on the social network. This defends 99% of Facebookers from spam, as stated by Facebook itself. The defense system happens to be the biggest in the world, equipped with 30 supervisors, enabled to learn and take actions on noticing suspicious behavior patterns.

The system, as it seems to me, is still far from the artificial intelligence. But is already able to combat massive viral script attacks within the network by blocking messages based on keywords once found and identified in spam chat messages.

Still unknown techniques make the system vulnerable. Social bots tend to fool the system, even adding thousands of friends and harvesting sensitive data like e-mail addresses. Due to peaking number of friend rejections spam bots receive, Facebook predicts improving FIS based on higher, than usual rejections amount.

I personally recently found out Facebook controls the speed of friends addition, if you add them too fast - you get considered to be a bot, even if you just re-add known people to the newly created account. If some people reject you, you already get blocked for a couple days, or a week without even a guess, who did it.

Still much job to do, but unless real artificial intelligence gets invented, we are going to face constant rules creating and breaking in this highly socialized world.

Today smartphones or tablet PCs are widespread. But what risks do we face? Lets check that out.

The most popular on the market Android OS tends to become an interesting target for world’s cutest brains. The simplicity of malicious applications distribution to phones and tablets brings evil ideas into everyday mobile life. Every unchecked application may be simply put on the Android market. This ensures quite high risk for end users.

IPads are insecure way to do business due to man-in-the-middle attacks vulnerability, and insecure cloud synchronization. Poor encrypting helps corporations, as they are main end users of IPads, loose their valuable data through the data leakage. Today these are the most dangerous devices in terms of security.

Jailbroken devices pose another risk. Most viruses work on such devices, as vendor jails prevent potentially unwanted activities. In most jailbroken IPhones the password for jailbreak hadn’t been modified, therefore viruses, fast spread with SSH, are very possible.

This is a truncated list of mobile insecurity. Currently no strong security is present for portable devices, using wireless connections.
