Today we face popularity of QR-codes. Most tech-savvy people already actively use them to transfer encoded digital information into their devices, to follow links and to  input data into their devices with no manual typing.

Some inventive “hackers” already started using this technique by sticking false QR-codes over real ones. So in case you use code-recognition client, which is automatically following links, and your Android phone does not ask you before installing apps other than those from Android market, you are in trouble. Such QR-codes might drive you to the download of a false operating system update, being a virus.

So beware of too much automation in your QR-reading software.

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.
