The CIA has been investigating ways to manipulate the control systems of modern cars and trucks that could be used for covert assassinations, WikiLeaks said on Tuesday as part of its dump of more than 8,700 documents that it claims are from the CIA’s Center for Cyber Intelligence.

“As of October 2014 the CIA was also looking at infecting the vehicle control systems used by modern cars and trucks,” WikiLeaks said in a statement. “The purpose of such control is not specified, but it would permit the CIA to engage in nearly undetectable assassinations.”
