SECURITY FIRM Sophos has shown how hackers can exploit user data from victims' machines using cryptography.

Demonstrating the walkthrough live at the Infosecurity Europe 2013 conference in London this week, Sophos' director of technology strategy James Lyne explained how hackers hide large volumes of data in seemingly innocent files to steal source code from businesses and individuals.

In the demo, Lyne shows how slightly reducing the quality of an image can leave space to hide a secret pattern using a freeware steganography tool called Openpuff, which can replace the original image on the victim's computer and steal the required data. µ
