FBI Disables Malware Used by Russia to Steal Government Documents

U.S. authorities said they disabled a piece of malware Russia’s intelligence agency has allegedly used for two decades to steal documents from NATO-allied governments and others, in an operation that highlights the FBI’s increasing efforts to go beyond arresting hackers and find new ways to disrupt cyberattacks. The operation effectively hobbled one of Russia’s most well-known and oldest cyber espionage groups, officials and security experts said, a vaunted hacking team that has been previously linked to devastating thefts of U.S. secrets.
