PARIS | Long-hidden hackers unmasked by US special counsel
PARIS — On the morning of March 19, 2016, Den Katenberg ran a little test with big stakes.
The previous week, Katenberg’s hacking crew had been bombarding the Hillary Clinton campaign’s email accounts with fake Google warnings, trying to get her Brooklyn-based staff to panic, enter their passwords and open their digital lives to Russia’s intelligence services.
But the going was tough. Even when Clinton staffers clicked the malicious links Katenberg crafted, two-factor authentication — a second, failsafe password test — still kept him out of their accounts.
