WASHINGTON, March 15 (Reuters) - Russian hackers appear to be preparing a renewed wave of cyber attacks against Ukraine, including a "ransomware-style" threat to organizations serving Ukraine's supply lines, a research report by Microsoft (MSFT.O) said on Wednesday. The report, authored by the tech giant’s cyber security research and analysis team, outlines a series of new discoveries about how Russian hackers have operated during the Ukraine conflict and what may come next. “Since January 2023, Microsoft has observed Russian cyber threat activity adjusting to boost destructive and intelligence gathering capacity on Ukraine and its partners’ civilian and military assets,” the report reads. Experts say the tactic of combining physical military operations with cyber techniques mirrors prior Russian activity. These developments have been paired with a growth in more stealthy Russian cyber operations designed to directly compromise organizations in countries allied to Ukraine, according to the report.
