A specialized unit inside mobile firm BlackBerry has for years enthusiastically helped intercept user data — including BBM messages — to help in hundreds of police investigations in dozens of countries, a CBC News investigation reveals.

BlackBerry gladly handed over subscriber and device information, communications, and even decrypted communications for law enforcement agencies in “dozens” of countries, according to a CBC report published Thursday that spoke to anonymous former employees in the company’s Public Safety Operations team, which works with law enforcement.

The company even offers global law enforcement a stock cover letter with checkboxes that indicate whether they wish to receive device and subscriber information, message logs, or “other,” which CBC reports as meaning decrypting messages secured with BlackBerry’s technology, which the company has touted for years.
