The former US government cyber security chief has called for the military to target organised criminal gangs of hackers who launch ransomware attacks on companies and governments. 

Chris Krebs, the ex-head of the US Cybersecurity and Infrastructure Security Agency, told the Financial Times the country needed to be more aggressive in hitting back against hackers who hold organisations to ransom by encrypting their data systems and demanding a fee to unfreeze them. 

He suggested military cyber attackers could try to deter gangs using ransomware by publishing their private details, a tactic known as doxing. “You’ve got to go after the bad guys, and I’m not just talking about law enforcement,” Krebs said in an interview with the FT.
