Russia has been stepping up its hacking efforts against Ukraine’s allies, including the US, according to Microsoft. 

On Wednesday, the company published a report documenting Russia’s malicious cyber activities since the war in Ukraine broke out. So far, Microsoft claims it’s detected Russian state-sponsored hackers trying to infiltrate 128 targets in 42 countries, which have been supporting Ukraine. 

49% of the targets were government agencies. The remainder were a combination of think tanks, humanitarian groups and private companies involved in Ukraine’s defense or economic sectors.

According to Microsoft, the goal behind the hacking efforts has been to steal sensitive information from governments that’ve been bolstering Ukraine’s defense against the Kremlin.

“While these targets are spread around the globe, 63% of this observed activity has involved NATO members,” the company added. The US, which is a NATO member, was targeted more than any other country at 12%. Meanwhile, Poland came in second at 8%.

In many cases, the targeted organizations have been able to thwart the hacking attempts, but not in every instance. “Since the start of the war, the Russian targeting we’ve identified has been successful 29% of the time,” wrote Microsoft President Brad Smith in a blog post. 

“A quarter of these successful intrusions has led to confirmed exfiltration of an organization’s data, although as explained in the report, this likely understates the degree of Russian success,” he added.  

According to Microsoft, the hacking efforts are part of a Russian campaign to undermine international support for Ukraine’s war effort. The company alleges the Kremlin is also trying to spread disinformation on US and European social media to erode the Western unity backing Ukraine. 

As a result, Microsoft is urging the international community to develop a comprehensive strategy that’s designed to counter Russia’s operations across the covert espionage and propaganda realms. “The war in Ukraine provides not only lessons but a call to action for effective measures that will be vital to the protection of democracy’s future,” Smith added.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
