Interpol Recovers $105 Million in Major African Cybercrime Sweep

Law enforcement agencies across 21 countries arrested 1,462 suspects and recovered over $105 million in illicit funds during a coordinated crackdown on digital fraud across the continent. Operation Serengeti III, which ran from June 29 to August 31, targeted ransomware, business email compromise, and online investment scams that cost victims more than $385 million in total losses.

For readers across Africa and the wider global financial system, this multi-jurisdictional sweep underscores the growing scale of transnational digital crime. As financial transactions increasingly move online, criminal networks leverage cross-border borders and digital assets to obscure illicit proceeds. Understanding how law enforcement tracks these networks is vital for safeguarding personal wealth and corporate systems.

Understanding the Scale of Operation Serengeti III

The operation dismantled 10,909 malicious networks and identified nearly 66,000 victims worldwide. Neal Jetton, Interpol's director of cybercrime, noted that these syndicates operate without regard for geographical boundaries, utilizing advanced technology to target individuals on an unprecedented scale. Private-sector partners, including major cybersecurity firms and blockchain analytics groups, provided critical intelligence that enabled authorities to map the fraudulent infrastructure.

This sweep follows earlier collaborative efforts such as Operation Catalyst in 2025, which targeted terrorist financing and digital fraud in partnership with Afripol. While criminals frequently experiment with various methods, digital assets and decentralized platforms remain a prominent tool for moving funds rapidly across borders. However, blockchain analytics firms are increasingly able to trace these transactions, providing investigators with definitive trails.

Crackdowns on Illegal Crypto Mines in Angola

Beyond software-based fraud, physical infrastructure tied to illicit digital asset activity also faced severe disruption. In Angola, investigators shut down two illegal crypto mining centers, arresting nine individuals and seizing more than 2,000 specialized computers used to mint digital tokens. Authorities also confiscated six unauthorized power transformation stations valued at over $1 million.

Crypto mining involves using high-powered computational hardware to solve complex mathematical problems and secure a blockchain network, consuming vast amounts of electricity. When conducted illegally, these operations strain national power grids and bypass regulatory oversight. Similar enforcement actions have targeted illicit operations globally, highlighting the physical footprint of digital finance.

Investment Scams and Arrests in Nigeria and Uganda

In West Africa, Nigerian authorities arrested a suspect linked to an international investment fraud scheme promoted through messaging applications. Investigators traced more than $2.4 million in suspected criminal proceeds, a significant portion of which was laundered through digital asset transactions. Another Nigerian suspect was detained for operating a phishing campaign that harvested approximately 2.1 million email addresses for business email compromise schemes. As we reported in our coverage of INTERPOL Arrests Nigerian Suspect in $2.4 Million Fraud Case, cross-border collaboration is increasingly vital for capturing suspects who exploit regional legal loopholes.

Meanwhile, Ugandan authorities dismantled two transnational syndicates and arrested 365 foreign nationals. These rings operated rotating call centers utilizing scripted pitches and fraudulent trading platforms to target pensioners in Asia. These sophisticated setups demonstrate how traditional boiler-room tactics have evolved into tech-enabled operations designed to deceive vulnerable savers.
