The risk of the Apache Log4j bug leading to a major data breach has prompted the Federal Trade Commission to demand that US companies patch the flaw or face a potential lawsuit. 

The FTC warning cites the growing number of hackers already targeting the flaw. “It is critical that companies and their vendors relying on Log4j act now, in order to reduce the likelihood of harm to consumers, and to avoid FTC legal action,” the regulator wrote. 

It’s rare for the commission to issue a legal threat over a software vulnerability. But in issuing its demand, the FTC points to the $650 million settlement it reached with credit bureau Equifax for a 2017 data breach involving the data of over 143 million US consumers. That breach was orchestrated using a two-month-old software flaw that Equifax had failed to patch, even though it was already known that hackers were exploiting the vulnerability.

The FTC is now hoping to avoid a repeat. The Log4J vulnerability is raising alarm bells because the Apache software is used across countless web and IT products as a tool to log changes. The flaw is also trivial to exploit, making it easy for hackers to spread malware on a vulnerable system, such as a company server. 

However, the problem mainly affects enterprises and government agencies, not regular  consumers, so it’s up to companies to act before hackers use the flaw to attack their systems. 

“The FTC intends to use its full legal authority to pursue companies that fail to take reasonable steps to protect consumer data from exposure as a result of Log4j, or similar known vulnerabilities in the future,” the agency says.

The FTC adds that it’s also scrutinizing how the IT industry relies on many open-source projects, such as Apache Log4J, to help run and maintain their software. The problem is that the same open-source projects are “often created and maintained by volunteers, who don’t always have adequate resources and personnel for incident response and proactive maintenance,” it says.

“This overall dynamic is something the FTC will consider as we work to address the root issues that endanger user security,” it adds.

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.
