The Unseen Danger: How a Company’s Hire Decision Led to a North Korean Cyber Attack

In the ever-evolving world of cybersecurity, companies continue to grapple with the challenge of safeguarding their digital assets from increasingly sophisticated threats. One such incident, which occurred in 2014, serves as a stark reminder of the unintended consequences that can arise from seemingly innocuous decisions.

The Background: A New Employee and an Unassuming Email

A mid-sized European defense contractor, which we’ll refer to as “DefCo,” was the unfortunate target of a cyber attack that would shake the industry and make headlines around the world. The initial point of entry for this attack, as it turned out, was an email received by a new employee named “Alex.”

Red Flags Overlooked

During the interview process, Alex had presented a strong resume and impressive technical skills. However, his background check raised some red flags due to inconsistencies in his employment history. These concerns were ultimately overlooked, as the hiring manager felt confident in Alex’s abilities and assumed that the discrepancies were minor.

Phishing Attack: The First Sign of Trouble

Just a few days after joining DefCo, Alex received a seemingly harmless email from a known supplier. The message contained an attachment labeled “Contract_Adjustment.zip,” which the antivirus software failed to detect as malicious. Alex, unaware of the danger, opened the attachment, inadvertently downloading a Trojan horse virus onto DefCo’s network.

Unraveling the Mystery: North Korean Connection

It wasn’t until several weeks later that the true nature of the attack came to light. Investigators discovered that the virus was part of a larger, more intricate campaign orchestrated by North Korean hackers. The ultimate goal: to infiltrate DefCo’s network and steal confidential data related to ongoing defense projects.

Lessons Learned: Due Diligence in Hiring

This incident serves as a powerful reminder that due diligence is crucial when it comes to hiring. By taking the time to thoroughly investigate potential employees and considering all available information, companies can significantly reduce the risk of bringing insidious threats into their organizations.

The Unassuming Hire: A Cybersecurity Nightmare

In the ever-evolving digital landscape, cyber attacks continue to pose a significant threat to individuals and organizations worldwide.
