In a plot twist that would make even the most cynical tech skeptic raise an eyebrow, a WhatsApp group chat has been exposed as the go-to financial hub for organised crime and extremism, moving hundreds of millions of euros in cash across the globe with all the subtlety of a bull in a china shop - minus the paper trail.
The group, aptly named "Traders of Greater Europe," boasted 532 members and was used to orchestrate cash transfers for clients, including destinations as far-flung as Birmingham and London. The European Broadcasting Union (EBU) investigative network, which includes the BBC, uncovered the scheme, which also facilitated payments from Brussels to Islamic State group (IS) militants in Syria.
Belgian investigating magistrate Vincent Guerra stumbled upon the group chat, which contained over 82,000 messages sent between late February and December 2022. Guerra described the volume of transactions as "staggering," noting the network spanned "the entire planet." The investigation initially focused on terror financing, but Guerra admitted it "became just a drop in the ocean of transactions."
The group relied on the ancient hawala transfer system, a network of trusted money brokers who settle payments without electronic records or physical cash movement. It's a system often used legitimately, like when immigrant workers send money home. But criminals love it because it bypasses the Swift system, where banks might raise an eyebrow at suspiciously large transfers.
Hawala is illegal in most of the EU, but in the UK, it's perfectly legal as long as brokers register with HMRC. Because nothing says 'law-abiding' like a cash-based, trust-me-bro system.
The WhatsApp messages were obtained after a 2024 Belgian court case that convicted six money launderers, including Abu Adam, the Brussels network's head, and his deputy Abu Ahmed. Belgian police found evidence the defendants were sending money to IS to help militants' wives escape detention camps in Syria. When they arrested Abu Adam, they hit the jackpot - his phone contained the group chat, along with 6,000 photos of €5 notes and 6,000 photos of identity cards, suggesting at least 12,000 transactions. Guerra marveled, "This isn't just amateur work; it's professional, and at a level we could never have imagined. They're bankers with no government oversight."
The EBU also found other gangs using hawala for criminal activities. One former money launderer, called Frank, admitted to handling several hundred million euros. He described his introduction to the system at an office outside Rotterdam, where messengers arrived with at least a million euros in about 90 minutes. Frank noted, "What I found out later is that it's not just about money. It's about the financing of terror. It's about drug trafficking. It's about prostitution and all sorts of other crap, to put it nicely."
Austrian cases revealed hawala's role in people smuggling. Police raided what they called "the biggest hawala office in Vienna," run from a kebab restaurant. Two Syrian brothers were charged with human trafficking and torturing a courier who lost €350,000. They were convicted and sentenced to 18 and 8 years. Austrian police and Europol also dismantled a smuggling ring that moved about 100,000 people into Europe over 18 months.
Gerald Tatzgern, who leads human-trafficking investigations at Austria's Criminal Intelligence Service, explained that torture is a tool of the trade. "Videos of the torture are then sent to the families, saying that if they don't send another €1,000 or several thousand euros, then the person concerned - your son, your brother, your father - will suffer." Payments were demanded via hawala, naturally.
Europol liaison officer Quentin Mugg called hawala "the primary money-laundering channel for organised crime," noting that hawaladars don't care if the money comes from migrant smuggling, human trafficking, or a grandmother's birthday gift. "And they'll apply their rates."
