A recent study has shed light on the true extent of North Korea's hacking operations, revealing that over 1,640 companies across 57 countries have been breached. The research highlights the use of fake job offers and external contractors to increase the potential blast radius of a successful attack. With this new information, cybersecurity experts and governments worldwide are taking notice, emphasizing the need for increased awareness and vigilance among organizations to protect themselves against these sophisticated attacks.
North Korea's hackers have breached over 1,640 companies across 57 countries. Around 700 to 800 organizations have had "really damaging" intrusions. The hackers used a tactic called "Contagious Interview," which lures software developers with fake job offers promising high salaries. External contractors were often compromised and gained access to multiple systems, increasing the potential damage. North Korea likely has several hundred skilled cyber operators who are trained from a young age. Cybersecurity experts warn that while North Korean hackers may be skilled, their focus on cryptocurrency theft poses a risk to other sensitive data.
North Korea's hackers have long been a source of concern for cybersecurity experts and governments around the world. For years, their stealthy operations have infiltrated companies, stolen corporate secrets, and plundered billions in cryptocurrency to fund the totalitarian regime and its weapons programs. However, recent research by a Greek-based cybersecurity researcher, Vangelis Stykas, has shed light on the true extent of North Korea's hacking operations.
According to Stykas, who gained access to North Korean systems 22 months ago, the country's hackers have breached over 1,640 companies across 57 countries. Among these, around 700 to 800 organizations have had "really damaging" intrusions, with company access, root access to servers, and even access to cryptocurrency wallets being reported.
Stykas' research, which will be presented at the Black Hat security conference in Las Vegas, reveals that North Korea's hackers used a simple yet effective tactic of luring software developers with fake job offers promising tempting high salaries. Once the target took the bait, the engineer would be asked to download a program as a test of their coding abilities, which would silently install malware on their machine.
This tactic, known as "Contagious Interview," has been used by North Korean hacker groups since 2022 and has proven to be highly effective in breaching organizations worldwide. In some cases, the hackers even infected themselves with their own malware, gaining access to their workstations and other systems.
Stykas' research also highlights the use of external contractors as a means to increase the potential blast radius of a successful attack. He notes that seemingly compromised external contractors, who often held developer keys or had system access to multiple systems, vastly increased the potential damage.
The scope of North Korea's hacking operations is both sprawling and fluid, according to a report published by cybersecurity firm Dtex last year. The country's cyber operators frequently adapt to support its priorities, such as economic and military development, espionage, and sanctions evasion.
The researchers found that North Korea likely has several hundred skilled cyber operators who are often trained from a young age. Additionally, there are "several thousand" IT workers who gain fraudulent remote employment at legitimate companies to earn money that can be funneled to the widely sanctioned regime.
Cyber and IT workers are both set yearly earnings quotas, according to the Dtex report. This highlights the lucrative nature of North Korea's cyber operations and the potential for significant financial gains.
However, Marcus Hutchins, a threat intelligence researcher for cybersecurity firm Expel, warns that while North Korea's hackers may be skilled, their focus on cryptocurrency theft can also pose a risk to other sensitive data. "It seems like the teams tend to stick to their task of getting crypto wallets," he notes. "But there's obviously the risk that if they're maintaining persistent access to a corporation, one of the espionage teams could then piggyback off that access."
Stykas' research has sparked concerns among cybersecurity experts and governments worldwide. The researcher notes that many of those companies held highly sensitive data that the hackers could have theoretically accessed – aside from the Boston Children's Hospital's store of health data, another US company held vast access to Americans' criminal records.
The real concern, however, should not be the companies named by Stykas but rather the ones he hasn't. Those companies include hundreds that never responded to his warnings, and more are added to the list every day.
"They're here, they're hacking us nonstop," Stykas says. "At the end of the day, everyone's getting hacked. How you treat it being hacked is what separates a good company from a bad company. And we have seen a lot of bad companies."
The incident highlights the need for increased cybersecurity awareness and vigilance among organizations worldwide. As the threat landscape continues to evolve, it is essential that companies prioritize security measures and invest in the latest technologies to protect themselves against sophisticated attacks.
In conclusion, North Korea's hacking operations are a significant concern for global cybersecurity. The extent of their breaching operations, as revealed by Vangelis Stykas' research, highlights the need for increased awareness and vigilance among organizations worldwide. By understanding the tactics used by North Korean hackers, companies can take steps to protect themselves against these attacks and prevent similar incidents from occurring in the future.
