While the crypto markets have not been immune to geopolitical developments, the sector in Iran experienced a more direct effect last week with a politically motivated $90 million exchange hack, prompting the authorities to introduce an exchange curfew. Blockchain analytics firm Chainalysis outlined on X on June 18 that Nobitex, Iran’s largest cryptocurrency exchange, had been hacked, with crypto assets to the value of $90 million having been drained from exchange-controlled wallets.Photo by Engin Akyurt on PexelsWeaponizing blockchain technologyThe hack had the hallmark of a politically-motivated attack given that rather than the digital assets being stolen, they were sent to vanity addresses, customized blockchain addresses involving user-defined sequences of characters. The vanity addresses contained “politically charged messages” and in sending the funds to them, the funds were effectively burned as they’re now permanently inaccessible.  The firm stated:”This incident highlights how crypto exploits aren’t always financially motivated. Bad actors can weaponize blockchain technology for geopolitical messaging, turning hacks into ideological statements rather than profit-driven crimes.” Pro-Israel hacker group Gonjeshke Darande, also known as “Predatory Sparrow,” appears to have carried out the hack, given that on June 18, it outlined on X that it would release Nobitex’s source code together with other internal information related to the firm’s internal network, while confirming that it had conducted cyberattacks against the company. The group made the following assertion:”The Nobitex exchange is at the heart of the [Iranian] regime’s efforts to finance terror worldwide, as well as being the regime’s favorite sanctions violation tool.” Rafe Pilling, director of threat intelligence at Sophos, a British cybersecurity company, told The Guardian that Predatory Sparrow “bears all the hallmarks of a false persona used by a government-sponsored threat group to conduct disruptive operations against targets” linked to the Iranian government. While Nobitex is estimated to have seven million users, an Open Source Intelligence (OSINT)-based investigation carried out in 2024 linked relatives of Ali Khamenei, Iran’s supreme leader, and other Iranian establishment figures to the crypto exchange. Minimizing systemic riskThe cyber attack has prompted a response from the Iranian government. In a blog post, Chainalysis outlined that the Central Bank of Iran has instructed all domestic crypto exchange platforms to curtail their service hours to between 10 a.m. and 8 p.m. The company speculated that this measure could be motivated by a desire to impose a higher level of oversight and control over the local crypto sector. However, it also suggested that it may be part of an attempt by the Iranian authorities to manage and minimize systemic risk. In recent years, Iran has been subject to extensive international sanctions applied by various entities including the United States, the European Union and the United Nations. Those sanctions have had a significant impact upon the country’s economy, triggering high inflation and currency devaluation.  With that, crypto has been increasingly viewed by the authorities as a means to circumvent sanctions. Last December, the Iranian authorities appeared to be working towards regulating crypto, embracing the asset class in acknowledgement of its growing importance to the Iranian economy. In February, Chainalysis reported that sanctioned entities worldwide had received $15.8 billion in crypto transactions in 2024.

In a major crackdown, the Chengdu Public Security Bureau announced on May 15 the dismantling of an extensive underground banking network, resulting in the arrest of 193 suspects across China in an operation that unveiled illegal businesses using the U.S. dollar stablecoin, Tether (USDT).Photo by DrawKit Illustrations on UnsplashUnauthorized foreign exchange settlements These activities involved illicit transactions amounting to approximately 13.8 billion yuan ($1.9 billion). The investigation began in November 2022 when authorities detected suspicious activities involving underground banks in Chengdu’s Longquanyi district. In response, a specialized task force was formed, integrating experts from various police departments, including economic investigation, cyber security and legal affairs. This team uncovered unauthorized foreign exchange settlements that bypassed national regulations. On June 1 of last year, acting on instructions received from the Ministry of Public Security, the task force conducted coordinated raids in several major cities, such as Shanghai and Shenzhen. These efforts led to the capture of key figures in the criminal syndicate, involving the arrest of 25 suspects. Law enforcement seized numerous bank cards, payment instructions and other digital payment instruments tied to the illegal operations during these raids. A broader investigation across 26 provinces has resulted in 193 suspects being arrested. Using USDT to evade regulationFurther investigations revealed that since January 2021, the syndicate exploited its import and export business to facilitate illegal activities. By using USDT as a medium, they bypassed official foreign exchange channels to service clients needing to transfer funds internationally. Moreover, these operations were intricately linked to other illicit activities, including financial fraud and smuggling. In a related development, on May 13, BeInCrypto reported that the Chinese government arrested six individuals responsible for illicit crypto transactions worth $295 million. These arrests highlight the challenges and risks associated with cryptocurrency in unregulated environments. Additionally, the Hong Kong police recently apprehended three men at a currency exchange shop following a deceptive transaction involving Tether’s USDT. The suspects allegedly showed a customer ceremonial "hell money" before deceitfully persuading him to transfer about $128,073 worth of USDT, only to refuse the agreed-upon cash exchange afterward.  According to the South China Morning Post (SCMP), hell banknotes are a form of ceremonial paper money burned as an offering to ancestors or deities in traditional Chinese culture. Late last year, USDT was used by a gang of gold smugglers in Nepal, who received $16 million in the Tether stablecoin in exchange for the precious metal. A joint investigation carried out by the authorities in Nepal and China led to the arrest of two Chinese and 13 Nepalese nationals in connection with the illicit activity. Over the course of the weekend, it emerged that two Chinese nationals had been charged by the authorities in the United States with money laundering through Bahamas-based Deltec Bank. Deltec acts as the primary banker for Tether, prompting longstanding Tether critics to suggest illicit activity relative to the stablecoin issuer’s dealings with the bank. This series of arrests and discoveries underscores the ongoing efforts of Chinese authorities to clamp down on illegal cryptocurrency activities. The activity also poses problems for Tether in its efforts to maintain compliance and stamp out illicit use in the face of ever-increasing regulatory scrutiny worldwide.
