The crypto world is no stranger to cyber threats, but the latest development has sent shockwaves through the community. North Korea’s notorious Lazarus Group, infamous for its cyber exploits, has unleashed a new and highly sophisticated malware variant that poses a grave risk to crypto firms. This malicious software, discovered in the context of the group’s fake job recruitment scams, has experts sounding the alarm bells due to its elusive nature.

In a detailed report by Peter Kálnai, a senior malware researcher at ESET, the cyber underworld’s newest threat was exposed. The discovery was made while investigating an elaborate ruse targeting a Spain-based aerospace company. This revelation introduces us to a previously unknown backdoor called “LightlessCan.”

The Lazarus Group’s Fake Job Scams

Lazarus Group has long been associated with fake job scams. Their modus operandi involves luring unsuspecting individuals with the promise of lucrative employment offers from reputable companies. Victims are duped into downloading what appears to be innocuous documents, but these files conceal devastating payloads that can wreak havoc when executed.

However, Peter Kálnai’s findings indicate a significant leap in Lazarus Group’s capabilities. LightlessCan, the newly discovered payload, is a formidable adversary, surpassing its predecessor, BlindingCan. What makes LightlessCan particularly concerning is its ability to mimic the functionalities of native Windows commands. However, this allows it to execute discreetly within the Remote Access Trojan (RAT) itself, avoiding noisy console executions.

Kálnai issues a strong cautionary statement, emphasizing, “This strategy provides a notable advantage by enhancing stealthiness, enabling it to evade real-time monitoring solutions such as EDRs and post-incident digital forensic tools.”

“Execution Guardrails” for Enhanced Stealth

Adding to the malware’s stealthiness, LightlessCan incorporates what Kálnai refers to as “execution guardrails.” These built-in security measures ensure that the payload can only be decrypted on the intended victim’s machine, making it virtually impenetrable to decryption attempts by security researchers. This innovation further enhances the malware’s ability to evade detection.

Cyberespionage at the Core

Kálnai underscores that the Lazarus Group’s attack on the Spanish aerospace firm had a primary objective: cyber espionage. The attackers sought to infiltrate the organization to gather valuable intelligence, emphasizing the group’s sophistication and relentless determination.

Lazarus Group’s Costly Track Record

The Lazarus Group and other North Korean hacking factions have inflicted substantial financial damage on the cryptocurrency sector since 2016. Their combined efforts have resulted in the theft of an estimated $3.5 billion from various cryptocurrency projects, according to a Chainalysis report from September 2023.

Additionally, a fake job scam campaign targeting potential victims on LinkedIn, known as “Operation Dream Job,” was flagged by cybersecurity firm SentinelOne in September 2022. This campaign impersonated recruiters, demonstrating the hackers’ adaptability and persistence.

In response to the escalating threat, international efforts led by the United Nations aim to curb North Korea’s cybercrime tactics, as it’s believed that stolen funds may be funding the nation’s nuclear missile program.

As Lazarus Group’s tactics continue to evolve and crypto firms remain lucrative targets, the need to bolster cybersecurity measures is more critical than ever. The crypto community must remain vigilant and proactive in the face of this ever-present danger.
