Justice Department says North Koreans have infiltrated dozens of U.S. companies


The U.S. Department of Justice is warning that hackers working for the North Korean regime are increasingly relying on Americans to facilitate the hacking of U.S. companies.

In an announcement on Tuesday, prosecutors said they have indicted and arrested at least two people, and conducted searches across dozens of suspected “laptop farms” in Texas. The computers were allegedly used by North Koreans to remotely hack into American companies and steal sensitive data.

According to the DOJ, federal authorities seized over 180 computers that they believe American companies had shipped out to their newly hired employees, not realizing that they were sanctioned North Korean spies who had used stolen identities of U.S. citizens to gain employment. The DOJ said that it raided over 40 laptop farms across Texas, the largest disclosed number of homes and residences used for facilitating North Korean hacks, which were owned by at least two American facilitators.

CrowdStrike, which helped the FBI investigate and disrupt the latest North Korean operations, said that laptop farms are “vital” to North Korea in helping its hackers overcome physical, financial, and legal challenges of not physically being in the United States.

The prosecutors said at least 70 U.S.-based companies had been infiltrated by the hackers, who are believed to have generated around $3 million in stolen funds. The DOJ did not name the affected companies, but described them as healthcare, cyber support, retail, communications, and manufacturing sectors across Ohio and 16 other states, including the District of Columbia.

“Increasingly, North Korean IT workers are turning to recruiting American facilitators to counter improved private sector detections and law enforcement actions. These workers are hiring facilitators to complete a wider variety of tasks, and in some cases subcontracting entire jobs to third-party foreign nationals,” the Justice Department said. 

Oftentimes, North Korean hackers use real-looking email addresses, spoofed LinkedIn profiles, and extensive online and social media accounts as cover for their activities.

In a separate public service announcement, the FBI said that there are “thousands” of North Korean-state controlled IT workers working at Western companies, which “pose a significant national security and intellectual property theft insider threat.”

This is the latest wave of arrests, indictments, and enforcement action targeting North Korean activities in the United States in recent years. The breakaway regime has used this “remote IT workers” scheme to allow North Koreans to gain employment with U.S. and European companies, earn a wage, and then steal sensitive information and intellectual property while as employees. The victim companies are then extorted into paying the hackers further. 

The remote IT workers’ scheme is one of several strands of illicit revenue that the North Korean regime aims to generate, including hacking crypto exchanges and open-source developer projects, with the aim of funding its internationally sanctioned nuclear weapons program. The regime is thought to have stolen at least $2 billion in crypto during 2025 alone.

Experts on North Korea have put the number of hacked companies and the amount of stolen crypto as likely much higher than reported.

Earlier this year, CrowdStrike said in a separate report that North Korean hackers were behind around half of all documented “hands-on-keyboard” intrusions over the past year, referring to hacks that are carried out by humans and not automated tools or AI.

Apple fixes bugs in macOS Sequoia that broke some cybersecurity tools


In September, Apple released the new version of its computer operating system macOS 15, also known as Sequoia, which broke the functionality of several cybersecurity products, including those made by CrowdStrike and Microsoft. 

Three weeks later, on Friday, Apple released the first update to macOS 15, and it claims to have fixed those issues. In the macOS 15.0.1 release notes, Apple says that the update “improves compatibility with third-party security software.”

Apple flagged the update in an email to TechCrunch on Thursday, and a spokesperson did not respond to a follow-up asking for more information. 

Patrick Wardle, the founder of macOS and iOS security startup DoubleYou, and a longtime expert on Apple security and the developer of several free security tools for macOS, wrote on X that the macOS update includes “a fix for the networking issues that plagued the initial macOS 15 release.”

“And to any Apple apologist who blamed 3rd-party vendors, you deserve to be slapped with a large trout as this was an Apple bug reported before [golden master],” Wardle wrote, referring to the first public release of the macOS 15 software.

When Apple first released macOS 15, several cybersecurity professionals said they were unable to use some security tools, such as CrowdStrike’s Falcon and Microsoft Defender, because of an apparent bug in the new macOS operating system. 

At the time, CrowdStrike spokesperson Kevin Benacci said that the company was “waiting for a macOS Sequoia update” to provide official support for its cybersecurity products on Apple’s operating system. 

Ugur Koc, a developer who works as a cloud engineer for for cloud managed service provider Glueckkanja, said on X that the new macOS update “resolves the issue with [Microsoft] Defender for Endpoint and other antivirus software, where the network filter was causing issues with the internet connectivity.”

Neither CrowdStrike nor Microsoft responded to a request for comment. 

Outage caused by CrowdStrike’s disastrous update affected 8.5 million devices


The global outage caused by a faulty update from cybersecurity provider CrowdStrike on Friday affected some 8.5 million Windows devices, Microsoft said in a blog post. The update triggered a blue screen of death, bringing systems used by hospitals, airlines, banks and other major services temporarily to a standstill. Only machines running Windows were affected.

While the issue was mostly resolved by Friday afternoon, Microsoft and CrowdStrike are still dealing with the fallout. In the blog post on Saturday, Microsoft’s VP of Enterprise and OS Security, David Weston, wrote that the company is working with CrowdStrike to “develop a scalable solution that will help Microsoft’s Azure infrastructure accelerate a fix for CrowdStrike’s faulty update.” Microsoft has also called in help from Amazon Web Services (AWS) and Google Cloud Platform (GCP).

CrowdStrike said in its own blog post on Saturday that the update — a sensor configuration update — “was designed to target newly observed, malicious named pipes being used by common C2 frameworks in cyberattacks.” Unfortunately, for devices running Windows 7.11 and above that use CrowdStrike’s Falcon sensor, it instead “triggered a logic error that resulted in an operating system crash.” The total number of devices affected worked out to be “less than one percent of all Windows machines,” according to Weston.
