As the US closes in on a COVID-19 vaccine, state-sponsored hackers from Russia and North Korea have been spotted trying to steal the research, Microsoft claims. 

“In recent months, we’ve detected cyberattacks from three nation-state actors targeting seven prominent companies directly involved in researching vaccines and treatments for COVID-19,” Microsoft VP for Security Tom Burt wrote in a blog post on Friday. 

The company alleges one of the hacking groups is Fancy Bear, which is best known for breaking into the Democratic National Committee in 2016.  The other two actors have been dubbed “Zinc” and “Cerium,” and both allegedly originate from North Korea

According to Microsoft, the state-sponsored hackers have targeted pharmaceutical companies and vaccine researchers based in Canada, France, India, South Korea, in addition to the US. 

“Among the targets, the majority are vaccine makers that have COVID-19 vaccines in various stages of clinical trials,’ Burt said, without naming the companies. “One is a clinical research organization involved in trials, and one has developed a COVID-19 test.” 

The bad news is that in some cases the hacking attempts were successful, although Microsoft blocked most of the attacks. “We’ve notified all organizations targeted, and where attacks have been successful, we’ve offered help,” Burt added. 

Microsoft didn’t say how it attributed the attacks to the state-sponsored groups. But in Fancy Bear’s case, the hackers have been using automated computer programs capable of inputting thousands of password combinations to break into people’s accounts. The North Korean hackers, on the other hand, have been spotted sending out spear-phishing emails, which can trick recipients into downloading malware or visiting a malicious website. The emails include pretending to be job recruiters or representatives of the World Health Organization. 

Microsoft revealed the findings to underscore why the world needs an international treaty banning cyberattacks against the healthcare industry. “We think these attacks are unconscionable and should be condemned by all civilized society,” Burt said. Microsoft President Brad Smith is participating in today’s Paris Peace Forum to lobby world governments for such a pact. 

In the meantime, the company has been offering healthcare organizations free access to Microsoft’s threat detection service known as AccountGuard. “Any health care-related organizations that wish to enroll can do so here,” Burt said. 

In July, cyber authorities in the US, UK, and Canada claimed another Russian hacking group, Cozy Bear, was also going after COVID-19 vaccine research. One of the group’s tactics has involved scanning the victim’s computer networks for publicly known vulnerabilities, and then trying to exploit them.

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.
