North Korean Crypto Hacks Plummet 80% – Is It Really Good News?

Hold on to your crypto wallets! It appears the volume of cryptocurrency pilfered by North Korean hackers has dramatically decreased, plunging a whopping 80% from the record highs of 2022. Sounds like a win, right? Well, not so fast, says blockchain forensics firm Chainalysis. They’re urging caution against popping the champagne just yet.

Let’s dive into the numbers. As of September 14th, 2023, North Korea-linked cybercriminals had snatched approximately $340.4 million in cryptocurrency. That’s a significant drop compared to the staggering $1.65 billion they reportedly looted in 2022. To visualize this dramatic shift, take a look at this chart:

Is the Decline in North Korean Crypto Hacks a Sign of Progress?

Don’t be fooled by the lower numbers, experts warn. Chainalysis, in their recent report, stated explicitly, “The fact that this year’s numbers are down is not necessarily an indicator of improved security or reduced criminal activity.” Why the skepticism?

Here’s the crux of the issue:

• 2022 Was an Exceptionally Bad Year: Last year’s $1.65 billion in stolen funds was an outlier, setting an alarmingly high benchmark. Comparing this year to such an extreme year might give a misleading sense of improvement.
• One Big Hack Can Change Everything: Chainalysis emphasizes the precariousness of the situation, stating,
  

  “In reality, we are only one large hack away from crossing the billion-dollar threshold of stolen funds for 2023.”

  This highlights that the threat is far from diminished.

• Recent Activity Shows Continued Threat: Even with the overall decrease, North Korea’s Lazarus Group has been actively making headlines recently.

Lazarus Group: Still a Force to Be Reckoned With

Despite the apparent drop in total stolen funds, the infamous Lazarus Group, linked to North Korea, remains highly active. Just in the past ten days leading up to the report, they’ve been connected to two significant crypto heists:

• Stake Hack (Sept. 4): A crypto gambling site, Stake, suffered withdrawals of approximately $40 million, suspected to be a hack.
• CoinEx Hack (Sept. 12): Crypto exchange CoinEx was reportedly targeted, resulting in losses of around $55 million.

These two attacks alone amount to over $95 million in stolen crypto in a short span. Chainalysis points out that North Korea-linked attacks now account for about 30% of all crypto funds stolen in hacks this year. That’s a significant chunk!

Erin Plante, Chainalysis’ vice president of investigations, emphasized the ongoing danger, telling Cointelegraph, “Lazarus continues to be prolific crypto thieves, which is made even more troublesome by the national security threat that DPRK poses.” Here’s a visual representation of how North Korean groups compare to others in the cybercrime landscape:

How Can Crypto Firms Bolster Defenses?

So, what can cryptocurrency firms do to protect themselves against these persistent threats? The answer, according to Plante, lies in strengthening the human element of cybersecurity:

• Employee Training is Key: Firms need to prioritize training employees to recognize and resist social engineering tactics.
• Social Engineering: A Favored Tactic: North Korean hackers, particularly Lazarus Group, are known for their sophisticated social engineering techniques. They exploit human trust and carelessness to infiltrate corporate networks.
• Focus on Warning Signs: Training should focus on identifying the red flags and warning signs of social engineering attempts.

“With North Korean-linked hackers in particular, sophisticated social engineering tactics that take advantage of the trusting and carelessness of human nature to gain access to corporate networks has long been a favored attack vector. Teams should be trained on these risks and warning signs.”

The Laundering Game: Dubious Exchanges and Mixers

Chainalysis’s report also sheds light on North Korea’s evolving money laundering strategies. They’ve observed a growing reliance on specific Russian-based cryptocurrency exchanges to clean their illicit gains over the past few years. This trend started picking up pace in 2021.

One notable instance of this involved a whopping $21.9 million laundered from the Harmony’s $100 million bridge hack in June 2022. Furthermore, sanctioned cryptocurrency mixers like Tornado Cash and Blender have been utilized by Lazarus Group in high-profile heists, including the Harmony Bridge hack and the Nomad Bridge incident.

Global Efforts to Combat North Korean Cybercrime

The international community is taking notice. The United Nations is actively working to curb North Korea’s cybercriminal activities on a global scale. Why the urgency? Because these stolen funds are believed to be funnelling directly into North Korea’s controversial nuclear missile program. Disrupting these illicit financial flows is crucial for international security.

Looking Ahead: Smarter Contracts, Stronger Defenses?

While the battle against North Korean crypto hackers is far from over, there’s hope on the horizon. Chainalysis believes that increased adoption of smart contract audits can make the crypto landscape a less attractive hunting ground for these cybercriminals. By identifying and fixing vulnerabilities in smart contracts before they are exploited, the industry can collectively raise the bar for security and make life significantly harder for hackers.

Key Takeaways: Don’t Let Your Guard Down

To summarize, while the numbers show a decrease in stolen cryptocurrency by North Korean hackers in 2023 compared to the previous year, it’s crucial to understand the nuances:

• Deceptive Decline: The 80% drop is largely due to the exceptionally high figures of 2022, not necessarily improved security.
• Lazarus Group Persists: Recent high-profile hacks demonstrate that Lazarus Group remains a potent threat.
• Social Engineering Focus: Employee training against social engineering is paramount for crypto firms.
• Evolving Laundering Tactics: North Korea is adapting its money laundering methods, utilizing Russian exchanges and mixers.
• Global Response Needed: International efforts and proactive security measures like smart contract audits are vital in combating this threat.

The cryptocurrency world is still a target, and vigilance is key. The apparent dip in stolen funds should not be misinterpreted as a victory but rather as a reminder that the fight against cybercrime, particularly from state-sponsored groups like those in North Korea, is an ongoing and evolving challenge.
