FBI repeatedly overstated encryption threat figures to Congress, public

The FBI has repeatedly provided grossly inflated statistics to Congress and the public about the extent of problems posed by encrypted cellphones, claiming investigators were locked out of nearly 7,800 devices connected to crimes last year when the correct number was much smaller, probably between 1,000 and 2,000, The Washington Post has learned.
Over a period of seven months, FBI Director Christopher A. Wray cited the inflated figure as the most compelling evidence for the need to address what the FBI calls “Going Dark” — the spread of encrypted software that can block investigators’ access to digital data even with a court order.
The FBI first became aware of the miscount about a month ago and still does not have an accurate count of how many encrypted phones they received as part of criminal investigations last year, officials said. Last week, one internal estimate put the correct number of locked phones at 1,200, though officials expect that number to change as they launch a new audit, which could take weeks to complete, according to people familiar with the work.
“The FBI’s initial assessment is that programming errors resulted in significant over-counting of mobile devices reported,’’ the FBI said in a statement Tuesday. The bureau said the problem stemmed from the use of three distinct databases that led to repeated counting of phones. Tests of the methodology conducted in April 2016 failed to detect the flaw, according to people familiar with the work.
