State-Backed Hacker Believed to Be Behind Follina Attacks on EU and US

An unidentified state actor is reportedly perpetrating a phishing campaign that targets European and local US government entities by leveraging the Follina Office vulnerability. Security researchers at Proofpoint spotted the hacking attempts and addressed the issue via Twitter last Friday from its Threat Insight account. In the series of tweets, the company describes the details of the campaign, including that it is targeting Proofpoint customers in the US and Europe.
