3 World-Class Hackers That Make Crypto Investors Uneasy

Jakarta, Pintu News – The year 2025 will be one of the darkest periods in cryptocurrency history. Whereas previously crypto scams were mostly rug pulls or small scams, now attacks are evolving into large operations involving state actors. In just the first six months of this year, total losses due to crypto hacks reached Rp35.99 trillion ($2.17 billion).

The situation became even more alarming in September 2025, when 20 crypto-related incidents were recorded with a loss value of around Rp2.1 trillion ($127.06 million). This figure shows how digital attacks on crypto exchanges, blockchain projects, and financial institutions are increasingly organized, demanding serious attention at the government level.

Lazarus Group

Lazarus Group is widely recognized as the most dangerous hacker group in the world, with a track record of activity dating back to 2007. They once shook the public with the Sony Pictures attack in 2014 and spread the WannaCry ransomware in 2017. In recent years, Lazarus’ main focus has shifted to the cryptocurrency industry.

According to data, from 2021 to 2025 Lazarus has stolen over IDR 82.9 trillion ($5 billion) worth of crypto. Their biggest stunt was recorded in February 2025, when they hacked into the Bybit exchange and made off with IDR 24.8 trillion ($1.5 billion) in Ethereum (ETH). This case set a record for the largest crypto theft in history, and showed how the group operates like a state cyber army.

Gonjeshke Darande

Unlike Lazarus, Gonjeshke Darande or Predatory Sparrow is a group known to be politically motivated and believed to be associated with Israel. Their main targets are Iran’s digital systems, including crypto exchanges. In June 2025, they managed to breach the security of Nobitex, the largest exchange in Iran, and stole around Rp1.49 trillion ($90 million) before burning the assets.

Not only that, the group also publicly released Nobitex’s source code, damaging the exchange’s reputation and fueling distrust from users and partners. Gonjeshke’s track record is nothing short of horrific: they crippled Iran’s train system in 2021, attacked a steel plant in 2022, and broke into Bank Sepah in May 2025. This emphasizes that crypto has now become part of global geopolitical conflicts.

UNC4899

Apart from Lazarus, North Korea also has another hacker unit called UNC4899. The Google Cloud Threat Horizons report said this group is under the command of the Reconnaissance General Bureau (RGB), the country’s main intelligence agency. Their operations focus on blockchain companies and crypto infrastructure through sophisticated methods such as supply chain attacks.

Between 2024 and 2025, UNC4899 was involved in a series of multi-million dollar crypto heists. They used a variety of techniques, from entrapment via Telegram with Docker malware, to stealing AWS cookies via LinkedIn to infiltrate cloud services. With these methods, they successfully copied billions of dollars worth of digital assets from their targets.
