Increasingly, security experts don't just want to know how a cyberattack happens, but what country the attack is coming from.
Headlines about hacking incidents have become commonplace, particularly in the recent months leading up to the U.S. Presidential election. Whether it's breaches of voter registration systems, the Democratic National Committee, or the World Anti-Doping Agency, experts are feverishly trying to figure out who is behind the crimes.
More specifically, they want to know whether a sovereign state could be supporting those attacks. Lately, they especially want to know if it's Russia.
Experts say the WADA perpetrators were Russian hackers operating under the banner "Fancy Bear," with several U.S. officials pointing fingers at the Russian government specifically.
Moscow has repeatedly denied involvement with that group and other international cyberattacks.
