North Korea’s Lazarus APT Is Targeting Blockchain Companies With Crypto-Stealer Malware

CPO Magazine - News, Insights and Resources for Data Protection, Privacy and Cyber Security Leaders

A joint cybersecurity advisory by the Federal Bureau of Investigation (FBI), the Cybersecurity and Infrastructure Security Agency (CISA), and the Treasury Department is cautioning about North Korea’s Lazarus APT focusing on blockchain companies.

The warning says Lazarus progressed determined danger (APT) bunch targets digital currency organizations with trojanized Windows and macOS cryptographic money applications.

The vindictive applications take private keys and take advantage of other security weaknesses to execute ensuing assaults and deceitful transactions.

U.S. specialists connected Lazarus to Ronin’s $625 million worth of Ethereum and USDC robbery. North Korean programmers have taken somewhere around $1.7 billion in digital currency in the beyond barely any years.

Lazarus APT targets representatives of blockchain organizations with counterfeit rewarding position offers

Lazarus APT purposes different correspondence stages to send an enormous number of lance phishing messages to workers of cryptographic money organizations. It for the most part targets framework chairmen, programming designers, or IT activities (DevOps).

“The messages often mimic a recruitment effort and offer high-paying jobs to entice the recipients to download malware-laced cryptocurrency applications, which the U.S. government refers to as ‘TraderTraitor.’ The campaign closely resembles the ‘Operation Dream Job’ detailed by an Israeli cybersecurity firm.

According to CISA, the Lazarus campaign distributes apps developed in JavaScript programming language targeting the Node.js runtime environment using the cross-platform Electron framework. The apps are forked from various open-source cryptocurrency projects. Apple revoked the developer certificates used to sign apps targeting the macOS ecosystem.

“In order to increase the likelihood of success, attackers target users across both mobile devices and cloud platforms,” Hank Schless, Senior Manager, Security Solutions at Lookout, said. “For example, at Lookout, we discovered almost 200 malicious cryptocurrency apps on the Google Play Store. Most of these applications advertised themselves as mining services in order to entice users to download them.”

CISA found that Lazarus APT sends different TradeTraitor variations like Dafom, TokenAIS, CryptAIS, CreAI Deck, AlticGO, and Esilet.

They guarantee different crypto-related administrations, for example, continuous cost forecast, portfolio building, AI-based exchanging, man-made brainpower, and profound learning.

Lazarus APT publicizes the trojans through sites with present day plans, maybe to persuade casualties regarding their usability.

“This campaign combines multiple popular trends into an attack,” Tim Erlin, VP of Strategy at Tripwire, said. “The alert from CISA describes a spear-phishing campaign that leverages the hot job market to entice users into downloading malicious cryptocurrency software.”

The danger bunch projects a wide net focusing on a wide range of blockchain organizations. As indicated by the joint warning, Lazarus APT targets digital money exchanging organizations, decentralized finance (DeFi) stages, play-to-procure digital currency computer games, digital money investment firms, and proprietors of huge digital currency resources or non-fungible tokens (NFTs).

“Non-fungible tokens (NFTs) have been in existence since 2014; however, perhaps entered the cultural mainstream in 2021. The hype surrounding NFTs will, however, invariably coincide with interest from cyber threat actors,” noted Chris Morgan, Senior Cyber Threat Intelligence Analyst at Digital Shadows.

How to safeguard blockchain organizations from Lazarus APT

U.S. offices distributed an extensive rundown of strategies, methods and methodology (TTPs) and marks of give and take (IoC) related with Lazarus APT. They encouraged blockchain organizations to apply different alleviations to limit Lazarus APT’s danger to the digital money industry.

According to CISA, blockchain organizations ought to execute security techniques, for example, least access models and protection in-depth.

Schless said that blockchain organizations ought to keep their representatives from becoming platforms for crypto-heist attacks.

“Crypto platform providers need to ensure that their employees are protected and don’t become conduits for cybercriminals to make their way into the infrastructure,” Schless proceeded. “Employees are constantly targeted by mobile phishing and other attacks that would give a cybercriminal a backstage pass to the company’s infrastructure.”

According to John Bambenek, Principal Threat Hunter at Netenrich, the North Korean danger will continue for the predictable future.

“North Korea has been focused on cryptocurrency threats for years because they are a highly-sanctioned country, and this lets them acquire assets they can use to further their governmental objectives,” Bambenek said. “This will continue until North Korea becomes a respectable member of the international community or the sweet meteor of death finally comes and ends all life on earth. The latter is the more accurate scenario.”
