Illegal Crypto Activity Surges in 2025, Chainalysis Finds

TheNewsCryptoPublished on 2026-01-09Last updated on 2026-01-09

Abstract

According to a Chainalysis report, illegal cryptocurrency activity surged by 162% in 2025, reaching approximately $154 billion, up from $59 billion in 2024. This significant increase was primarily driven by sanctioned entities and nation-states, such as Russia, using blockchain networks to evade financial restrictions. The report highlighted that 2025 marked a turning point, with unprecedented on-chain activity reflecting greater sophistication and coordination among these actors. Stablecoins accounted for about 84% of illegal transaction volume due to their stability and ease of cross-border transfer. Despite the sharp rise, illegal transactions still represent less than 1% of total on-chain activity.

The illegal crypto activity has unexpectedly surged in 2025 as sanctioned nation capitals and bodies have used blockchain networks to avoid financial restrictions, as per the 8th January report of Chainalysis.

In 2025, the overall illegal crypto addresses accumulated around $154 billion, showing a 162% increase from $59 billion in 2024, as per the report. The increase was mainly influenced by sanctioned bodies moving funds on-chain at scale.

Chainalysis reported that 2025 was a turning point, mentioning unprecedented volumes linked with the on-chain behaviour of nation-states and referring to it as the recent phase in the evolution of the illegal crypto ecosystem.

The firm further highlighted that the scale and coordination of activity were not similar to previous years, showing increasing sophistication among sanctioned actors. Russia, which has experienced extensive international sanctions since its capturing of Ukraine, came up as a major contributor to the increase.

In February last year, the country introduced a ruble-supported token named A7A5. The token generated over $93.3 billion in transactions in less than one year, the report mentions. The growth of sanctions over the world has accelerated pressure on sanctioned parties to look for an alternative payment system.

The Increased Activity

The Global Sanctions Inflation Index approximated in May that around 80,000 bodies and individuals were under sanctions over the globe. Research from the Center for a New American Security stated that the US introduced 3,135 more bodies to its Specially Designated Nationals and Blocked Persons List in 2024, the highest annual total on record.

Stablecoins accounted for about 84% of all illegal transaction volume last year, Chainalysis reported. The company accredited their prevalence to price stability, easy cross-border transfers, and widespread liquidity, highlighting that the same features influencing legitimate adoption have also captivated sanctioned users.

Regardless of the sharp increase in illegal volumes, criminal activity is still a small fraction of the total crypto economy. Illegal transactions are still 1% less as compared to overall on-chain activity; however, their share increased comparatively year over year.

Coldcard Hardware Wallet Hacked: Losses Mount Due to Vulnerable Seed Generation A critical vulnerability in Coldcard hardware wallets has led to a continued wave of fund thefts. According to Galaxy Research, the total stolen has reached 1,367.05 BTC (approx. $88.6 million) from 4,585 addresses, a significant increase from the initial 594.5 BTC reported on July 30, 2026. Most of the stolen funds remain on the attackers' addresses. The issue is not with the current firmware, which Coinkite has updated, but with seed phrases generated on vulnerable devices between March 2021 and the release of fixed firmware versions. Due to a programmer error, devices switched from using a hardware random number generator to the software-based Yasmarang generator, which was initialized with publicly accessible data like the chip's serial number. This made the seed phrases predictable through offline brute-force attacks, meaning wallets remain at risk until funds are moved to a new wallet generated with the patched firmware. Affected devices include Mk2/Mk3 with firmware 4.0.1–4.1.9 (and up to 5.0.3), Mk4/Mk5 up to version 5.6.0, and Q models up to 1.5.0Q. The only exceptions are seeds created with a high-entropy method like at least 50 independent dice rolls or a strong unique BIP-39 passphrase. All other owners must generate a new seed on the fixed firmware and transfer their assets. A case highlighting the human impact involves a 39-year-old long-term investor who lost 2 BTC (approx. $130,000) in minutes. He had accumulated the Bitcoin over eight years through physical labor, viewing it as a financial lifeline and a retirement plan in a country suffering from hyperinflation. His story underscores that even conservative "buy and hold in cold storage" strategies can be compromised by such underlying technical flaws. From a technical perspective, this incident echoes historical failures where weak random number generators undermined cryptographic security, challenging the assumption that offline storage is automatically foolproof.
