US Cyber Command Investigates Unusual Spike in Suicides

The US military’s cyberwarfare unit is scrutinizing an unusually high number of deaths by suicide among personnel over a month-long period this summer, according to government officials and other people familiar with the matter.

The deaths have worried US lawmakers and military leaders within the secretive section of the armed forces, which defends American computer systems and hacks foreign adversaries, according to the people and records reviewed by Bloomberg News. They’ve also resurfaced officials’ longstanding concerns about the mental health of military hackers who have over the last year seen their workload surge because of foreign conflicts.
