Sky ECC, an encrypted phone company whose users include criminals, claims someone created a fake version of its communication app, loaded that onto phones, and then sold those phones through "unauthorized channels," a representative for the company told Motherboard.

Sky ECC is responding to media reports Tuesday that said law enforcement agencies had managed to crack Sky's communication platform at the end of last year, and authorities had obtained suspects' thought-to-be-secure messages in real-time. The company is claiming to Motherboard, essentially, that law enforcement or someone else advertised and sold phones loaded with counterfeit apps. Then, seemingly, law enforcement observed criminal activity on these compromised devices, allowing them to make the arrests that were reported Tuesday.
