What better way to sell your wares than to produce a marketing video showing exactly how your product works? Even if that product is spyware, marketed to oppressive regimes.

WikiLeaks, as part of its Spy Files trove of documents, released on Thursday a series of videos from Gamma International, a UK-based firm that markets the Finfisher spyware. The video shows how the company’s product can be used to sniff WiFi networks from a hotel lobby, hack computers and cell phones, or intercept Skype communications and siphon encryption passwords.

Additionally, Gamma, which was found to have marketed its tools to Hosni Mubarak’s regime before Egyptian protestors toppled him, asserts in one of its videos that it has the ability to send a “fake iTunes update” to targets to infect their computers with the company’s surveillance software – though Apple has reportedly fixed the bug it exploited.
