UK Crypto Exchanges Linked to IRGC Sanctions Evasion Network
Two cryptocurrency exchanges incorporated in the United Kingdom, Zedcex and Zedxion, functioned as financial infrastructure for Iran’s Islamic Revolutionary Guard Corps, concluded on-chain and corporate analysis by TRM Labs.
Although registered as separate entities, the exchanges appear to operate as a single enterprise, sharing directors, virtual addresses and mirrored filings that obscure true control. Between 2023 and 2025, wallets linked to the exchanges processed roughly $1 billion associated with the IRGC, accounting for about 56% of total activity and peaking at 87% in 2024.
The network traces back to Babak Zanjani, an Iranian financier previously sanctioned for laundering oil revenues for regime entities. Most transactions flowed through USDT on the tron blockchain, effectively turning Zedcex into a stablecoin clearing hub rather than a retail exchange, TRM Labs said. On-chain data also shows direct transfers exceeding $10 million to a U.S.-designated Houthi terrorist financier.
Malicious NPM Packages Spread New NodeCordRAT Malware
Cybersecurity researchers identified three malicious npm packages used to distribute a previously undocumented remote access Trojan dubbed NodeCordRAT. The packages – bitcoin-main-lib, bitcoin-lib-js and bip40 – were uploaded by a user named “wenmoonx.”
The attackers appear to have named the packages to resemble legitimate components of the popular bitcoin ecosystem. Developers collectively downloaded them several thousand times before the packages were removed in November.
Zscaler ThreatLabz said NodeCordRAT relies on Discord servers for command-and-control communications. Once installed, the malware can steal Google Chrome credentials, API tokens and cryptocurrency wallet seed phrases, including those from MetaMask.
FBI Warns of North Korean Quishing Campaigns Using Malicious QR Codes
The FBI published an advisory warning that North Korean state-sponsored hackers are using malicious QR codes in targeted spear-phishing campaigns against U.S. and international organizations. The bureau attributed the activity to Kimsuky, also known as APT43, a threat group linked to North Korea’s Reconnaissance General Bureau. The group is using a tactic known as “quishing,” which embeds QR codes in emails in a bid to pivot users onto mobile devices in order to bypass traditional email security controls.
Kimsuky used the QR codes in multiple campaigns during May and June, spoofing diplomats, advisors and think tank staff to solicit information, deliver fake secure links or harvest Google account credentials through fraudulent login pages. The group has a history of exploiting weak DMARC configurations to make phishing emails appear legitimate.
The FBI warned that quishing often enables session token theft, allowing attackers to bypass multi-factor authentication, hijack cloud identities and spread further phishing from compromised accounts.
Illicit Crypto Activity Hit $154B in 2025
Illicit cryptocurrency activity surged to a new high in 2025 as state actors relied on criminal networks to evade global financial restrictions, showed a Chainalysis report. The firm estimates that illicit addresses received at least $154 billion during the year, a 162% increase from the prior year’s revised total, driven largely by sanctions evasion and other state-linked activity. Chainalysis said that the figure represents a lower-bound estimate and is likely to grow as more illicit addresses are identified.
North Korea led state-linked activity, with hackers stealing $2 billion, largely from the $1.5 billion Bybit exploit. Russia made heavy use of the ruble-backed A7A5 stablecoin, while Iran-aligned networks and Chinese money laundering groups also played major roles. Stablecoins made up 84% of illicit volume, reflecting their growing dominance in cross-border crypto crime.
Trump Rules Out Pardon for Ex-FTX CEO Sam Bankman-Fried
U.S. President Donald Trump reportedly said he will not pardon former FTX CEO Sam Bankman-Fried, amid speculation that the jailed crypto executive might receive clemency. Trump made the remarks during an interview with The New York Times, where he addressed potential pardons for several controversial figures but explicitly excluded Bankman-Fried from his list of clemency considerations.
Bankman-Fried was convicted in 2023 on multiple fraud and conspiracy charges stemming from the collapse of his now-defunct cryptocurrency exchange, FTX. He is serving a 25-year prison sentence.
The decision contrasts with Trump’s previous clemency actions, such as pardons for former Binance CEO Changpeng Zhao and Silk Road founder Ross Ulbricht. Trump also reaffirmed his support for the broader crypto industry, which remains a key part of his political messaging.
