Law enforcement agencies across 19 African countries, coordinated by INTERPOL under Operation Sentinel, arrested 574 suspects and recovered approximately $3 million in a sweeping crackdown on cybercrime. The month-long operation targeted business email compromise (BEC), digital extortion, and ransomware, resulting in the takedown of over 6,000 malicious links and the decryption of six ransomware variants. Notable incidents included the prevention of a $7.9 million BEC fraud at a Senegalese petroleum company, a ransomware attack on a Ghanaian financial institution that encrypted 100 terabytes of data, and the dismantling of a cross-border scam in Ghana and Nigeria that defrauded over 200 victims. Authorities also seized more than 100 digital devices, took down 30 servers, and shut down thousands of scam-linked social media accounts, with total financial losses from investigated cases exceeding $21 million.
The operation highlighted the increasing scale and sophistication of cyberattacks targeting critical sectors such as finance and energy across Africa. International cooperation and rapid response were key to the operation's success, with support from private sector partners including Team Cymru, The Shadowserver Foundation, Trend Micro, TRM Labs, and Uppsala Security. The results demonstrate a strong commitment by African law enforcement and their international partners to combat cybercrime and protect digital infrastructure in the region.
