BoxCryptor – On-the-fly Encryption for cloud storage

BoxCryptor is a free tool that secures your data in the cloud – no matter if you use Dropbox, SkyDrive, Google Drive or any other cloud storage provider. It does so on OSX, iOS, Linunx, Android, Windows and even Windows RT.

BoxCryptor works by on the fly encrypting all data that you place in a dedicated folder resp. network mount before it’s synced to the cloud. It uses the AES-256 standard for encryption.

Wideband GSM sniffing

Last years Chaos Computer Club Congress in Berlin already had a talk about this topic. This year, GSM eavesdropping has actually been demonstrated using a cheap of the shelf Motorola phone with an open source GSM firmware as a listening device. Karsten Nohl and Sylvain Munaut replaced the firmware on the phone, enabling them to process all the data it received. They used already available 2 Terrabytes of rainbow tables to decrypt data being sent to and from other mobile phones. They have no plans to release the hack publicly, however they expect others to successfully attempt the hack. Mr. Nohl said the objective was to raise awareness of GSM insecurity. Yikes!
