A forensic analysis released Friday indicated the same Russian group that hacked the Democratic National Committee was responsible for hacking the Democratic Congressional Campaign Committee.

The group, which is formally designated as APT 28 but known more famously as “Fancy Bear,” is highly sophisticated and linked to the Russian government. “It typically does two things,” said Christopher Porter, a team manager at cybersecurity firm FireEye. “They conduct espionage against some defense targets, and information operations where they’re trying to put out a message.”
