The same Russian government-aligned hackers who penetrated the Democratic Party have spent the past few months laying the groundwork for an espionage campaign against the U.S. Senate, a cybersecurity firm said Friday.

A hacking group heavily linked to the Russian government is attempting to steal U.S. Senate email login credentials and also appears to be preparing to disrupt the 2018 Winter Olympics in South Korea, according to new research by cybersecurity firms TrendMicro and ThreatConnect.

The US Senate was targeted last year by the same hacking group that broke into the Democratic National Committee servers during the 2016 presidential election, according to the cybersecurity firm Trend Micro.

Pawn Storm, the hacking group aligned to the Russian government that penetrated the Democratic National Committee, has mounted additional "brazen attacks" over the past eight months, including persistent targeting of the U.S. Senate internal email system, according to a cybersecurity firm that has tracked their progress.
