INTERPOL’s Major Crackdown on Cybercrime in Africa
A recent operation led by INTERPOL marked a significant step forward in the fight against cybercrime in Africa. Coordinated under the title Operation Sentinel, this initiative resulted in the arrest of 574 suspects across 19 countries. Authorities recovered $3 million while dismantling networks involved in various cybercrimes.
Moreover, the initiative, which ran from October 27 to November 27, 2025, specifically targeted business email compromise, digital extortion, and ransomware. Participating nations included Benin, Nigeria, and South Africa, among others. During this operation, law enforcement agencies took down over 6,000 malicious links and decrypted six different ransomware variants, revealing financial losses equating to more than $21 million.
In addition, Ghanaian authorities acted decisively against a ransomware attack that affected a local financial institution, resulting in the encryption of 100 terabytes of data and a theft of approximately $120,000. The operation also uncovered a cyber fraud network between Ghana and Nigeria, which swindled over $400,000 from more than 200 victims through deceptive websites impersonating well-known fast-food brands.
Ukrainian Ransomware Affiliate Admits Guilt
In a notable turn of events, a 35-year-old Ukrainian national recently pleaded guilty to his involvement in Nefilim ransomware attacks. The individual, arrested in Spain in June 2024, faced charges related to actions that targeted businesses in the U.S. and abroad.
Federal authorities revealed that he gained access to the Nefilim ransomware code in exchange for a share of the ransom proceeds. Investigations showed that he and his accomplices targeted companies with significant annual revenues, establishing a troubling link to the global ransomware epidemic. Nefilim operated under a double extortion model, threatening to publish stolen data if victims refused to pay.
The guilty plea solidifies the ongoing crackdown on international cybercrime. Scheduled for sentencing on May 6, 2026, the individual could face up to 10 years in prison, reflecting the severe judicial response to cyber offenses.
