Operation Sentinel: A Pan‑African Assault on Cyber‑Enabled Financial Crime, Recovering $3 M and Securing 574 Arrests

Breaking: Pan-African crackdown on cybercrime yields hundreds of arrests and multimillion-dollar seizures

In a coordinated, INTERPOL-led push spanning 19 African nations, authorities dismantled extensive cyber-enabled financial networks. The operation, conducted from late October to late November 2025, resulted in 574 arrests and the recovery of about USD 3 million in illicit proceeds. It stands as one of the region’s largest multi-country cybercrime crackdowns to date.

Scope, objectives and approach

Operated under the African Joint Operation against Cybercrime, the initiative targeted business email compromise, ransomware, digital extortion, and online fraud. The effort reflects a strategic shift in how authorities view cybercrime: a transnational financial ecosystem that demands cross-border disruption across networks, payment rails, and infrastructure, not just post-incident prosecutions.

Global partnerships and real-time disruption

National agencies joined forces with international partners and private-sector experts to map malicious infrastructure, trace financial flows, and intervene swiftly. partners included threat intelligence firms and security researchers who helped identify domains, infrastructure, and wallet activity.The collaboration enabled real-time actions such as takedowns of malicious links and targeted account freezes, aimed at stopping losses as thay occurred.

Case highlights from the operation

Senegal: Investigators halted a business email compromise scheme targeting a petroleum firm. Fraudsters tried to redirect USD 7.9 million via forged invoices and spoofed messages, but authorities froze destination accounts before funds could be withdrawn.

Ghana: A ransomware attack against a financial institution encrypted roughly 100 terabytes of data and stole about USD 120,000. Investigators identified the malware and, with partners, developed a decryption tool that recovered nearly 30 terabytes, mitigating long-term harm.

Ghana–nigeria: A joint probe dismantled a transnational scam network using fake food-delivery sites and apps to defraud more than 200 victims.ten suspects were arrested, over 100 devices seized, and 30 fraudulent servers shut down.

Benin: Authorities shut down 43 malicious domains and over 4,300 social media accounts tied to extortion, impersonation and fraud, leading to more than 100 arrests and massive disruption across several countries.

Financial-crime dynamics and technology at work

Investigations show cybercriminals rapidly move funds across multiple wallets and intermediaries. Proceeds are mixed with traditional banks,mobile money,and crypto platforms to launder and cash out. Private-sector support, including blockchain tracing, proved crucial for identifying wallet infrastructure and enabling emergency freezes when possible.

Criminal funds frequently enough flow through numerous addresses and channels before cashing out.

Enforcement significance and outlook

Experts note the operation demonstrates how African law enforcement can scale cybercrime response with international coordination and technical aid.The emphasis on active disruption—freezing accounts and disabling infrastructure during ongoing attacks—underscores a proactive approach, rather than waiting for post-incident investigations.

Officials say the effort also highlights the value of public-private collaboration and real-time intelligence in securing livelihoods, protecting sensitive data, and safeguarding critical services. International partners stress that sustained cooperation is essential as threats grow more automated and cross-border in nature.

Looking ahead, cyber-enabled financial crime is evolving rapidly. Analysts expect criminal networks to continue leveraging automation and cross-border infrastructure to maximize impact. The operation signals that coordinated enforcement, paired with blockchain intelligence and swift intervention, can meaningfully reduce harm.

TRM Labs and similar entities continue to provide investigative support to law enforcement in complex financial-crime cases, reinforcing the importance of cross-border cooperation in tackling these networks.

looking forward: lessons for readers and policymakers

Cross-border collaboration remains a cornerstone of effective cybercrime response. This crackdown demonstrates how public-sector leadership, private-sector intelligence, and real-time actions can disrupt criminal ecosystems in real time.
