UPDATE: CrowdStrike has also spotted cybercriminals using the outage as bait to hack prospective targets. This includes "impersonating CrowdStrike staff in phone calls," and "posing as independent researchers, claiming to have evidence the technical issue is linked to a cyberattack."

Original story:
Watch out for emails that claim to come from CrowdStrike. Hackers have been quick to exploit Friday’s massive IT outage by posing as the cybersecurity company behind the disruption. 

The US Cybersecurity and Infrastructure Security Agency (CISA) and UK National Cyber Security Centre issued alerts warning about phishing emails attempting to capitalize on the chaos.

"An increase in phishing referencing this outage has already been observed, as opportunistic malicious actors seek to take advantage of the situation. This may be aimed at both organizations and individuals," the UK agency said.

The US-based SANS Technology Institute, which promotes cybersecurity, issued a similar warning. “Some reports we have seen indicate that there may be phishing emails circulating claiming to come from ‘Crowdstrike Support’ or ‘Crowdstrike Security,’” wrote Johannes Ullrich, the dean of research at the institute. 

“I do not have any samples at this point, but attackers are likely leveraging the heavy media attention. Please be careful with any ‘patches’ that may be delivered this way,” he added. “One domain possibly associated with these phishing attacks is: crowdfalcon-immed-update [.] com.”

The outage represents a ripe opportunity for cybercriminals since it's affecting numerous companies, including airlines. In total, CrowdStrike has about 29,000 enterprise customers — many of which are likely scrambling to resolve Friday’s disruption

CrowdStrike has issued an advisory on how companies and individual users can restore affected Windows systems, which has been sourced to a faulty software update. Nevertheless, phishing emails dressed up to look like the cybersecurity vendor could trick customers desperate for help. 

The Texas Department of Information Resources added that's it's been "receiving reports that bad actors are impersonating CrowdStrike employees to gain access credentials."

Some cybersecurity researchers have also spotted someone registering several internet domains using the names such as “crowdstrikebluescreen[.]com,” and “crowdstrike0day[.]com” — a sign that hackers are preparing to create numerous scam websites to exploit the outage.

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.
