Could CodeLock Stop North Korean Hackers?

An Attack from the North

‍
It all started innocently enough. KnowBe4, known for its programs that teach employees to recognize phishing attacks and other cyber threats, needed to expand its team. After a rigorous interview process and thorough background checks, they hired a remote software engineer who appeared to be the perfect fit. Little did they know that they had just opened their virtual doors to a seasoned cybercriminal.

The first sign of trouble came when the new hire received a company-issued Mac. Almost immediately, the computer began to act strangely, loading malware without any apparent reason. The company’s onboard security software detected the anomaly, setting off alarm bells. KnowBe4's IT team quickly initiated an investigation, calling in reinforcements from the FBI and Google’s security arm, Mandiant.

What they uncovered was astonishing. The malware had been introduced by the new hire, who was actually a North Korean hacker posing as an IT worker. This hacker had gone to great lengths to infiltrate the company, using a combination of stolen identities and AI-enhanced photos to pass the interview process. The investigation revealed that the hacker had manipulated session files and executed unauthorized software, including using a Raspberry Pi to load the malware.

When the malware was first detected, KnowBe4’s IT team reached out to the employee. The hacker, maintaining their cover, claimed they were troubleshooting a speed issue on their router. But the company’s security systems told a different story. As the investigation deepened, the hacker became unresponsive, cutting off all communication.

Further digging revealed that the work computer had been shipped to an address used by a network of "IT mule laptop farms," which the hacker accessed via VPN. Despite the sophisticated ruse, KnowBe4 managed to contain the threat remotely, preventing any compromise of their internal systems.

This incident is a stark reminder of the relentless efforts by North Korean hackers to infiltrate US companies. In May, US authorities warned that North Korean groups had been using stolen identities from over 60 real US persons to secure remote IT jobs. These positions not only generate revenue for illegal programs but also provide a gateway for stealing confidential information and paving the way for more significant attacks.

In response to the breach, KnowBe4 has urged the industry to adopt more robust vetting processes and continuous security monitoring. They recommend conducting video interviews to verify candidate identities and thoroughly checking references beyond simple email verifications.

KnowBe4 shared that the North Korean hacker had successfully cleared multiple video interviews, presenting an AI-enhanced photo of a real but stolen US identity. This deception highlights the sophisticated methods used by cybercriminals to bypass traditional security measures.

‍How CodeLock Could Have Thwarted the Attack‍

Had KnowBe4 been using CodeLock, a cybersecurity tool designed to provide protection from development through deployment, this breach might have been avoided altogether. CodeLock's advanced threat detection and real-time monitoring capabilities could have identified the malicious intent much earlier, even during the hiring process.

Key Points Where CodeLock Could Have Made a Difference:

1. Enhanced Vetting with Advanced AI:CodeLock’s AI-driven vetting process could have identified anomalies in the applicant’s background, potentially flagging inconsistencies that conventional background checks missed. This would have provided an additional layer of scrutiny, making it harder for the hacker to pass the interview process.
2. Real-Time Monitoring:Once the Mac was issued, CodeLock’s real-time monitoring system would have detected the suspicious activities immediately. The system’s advanced threat detection capabilities would have raised red flags the moment any unauthorized software manipulation was attempted.
3. Seamless Coordination Between HR, IT, and Security Teams:CodeLock facilitates better coordination between HR, IT, and security teams. This integrated approach ensures that any potential threat is addressed holistically, from the hiring process to daily operations. In KnowBe4’s case, such coordination could have led to earlier detection and prevention of the breach.
4. Proactive Threat Containment:CodeLock’s ability to remotely contain threats would have added another layer of security. Even if the hacker managed to infiltrate the system, CodeLock’s proactive threat containment measures would have swiftly isolated and neutralized the threat, minimizing potential damage.

While KnowBe4 managed to thwart the breach, the incident highlights the persistent threat of North Korean hackers exploiting remote IT jobs to infiltrate US companies. The US government has warned about such tactics, noting that North Korean hackers often use stolen identities to secure remote positions, enabling them to generate revenue for illegal programs and steal confidential information.

In the wake of this incident, KnowBe4 is advising industry peers to enhance their vetting processes, conduct video interviews to verify candidate identities, and perform thorough reference checks. However, adopting a comprehensive cybersecurity solution like CodeLock could provide even greater protection against such sophisticated threats, ensuring that companies remain secure from development through deployment.
