INTERPOL-coordinated operation leads to 1,209 arrests

interpol.int - LYON, France 22.08.2025 – In a sweeping INTERPOL-coordinated operation, authorities across Africa have arrested 1,209 cybercriminals targeting nearly 88,000 victims.

The crackdown recovered USD 97.4 million and dismantled 11,432 malicious infrastructures, underscoring the global reach of cybercrime and the urgent need for cross-border cooperation.

Operation Serengeti 2.0 (June to August 2025) brought together investigators from 18 African countries and the United Kingdom to tackle high-harm and high-impact cybercrimes including ransomware, online scams and business email compromise (BEC). These were all identified as prominent threats in the recent INTERPOL Africa Cyberthreat Assessment Report.

The operation was strengthened by private sector collaboration, with partners providing intelligence, guidance and training to help investigators act on intelligence and identify offenders effectively.

This intelligence was shared with participating countries ahead of the operation, providing critical information on specific threats as well as suspicious IP addresses, domains and C2 servers.

Operational highlights: From crypto mining to inheritance scams

Authorities in Angola dismantled 25 cryptocurrency mining centres, where 60 Chinese nationals were illegally validating blockchain transactions to generate cryptocurrency. The crackdown identified 45 illicit power stations which were confiscated, along with mining and IT equipment worth more than USD 37 million, now earmarked by the government to support power distribution in vulnerable areas.

Zambian authorities dismantled a large-scale online investment fraud scheme, identifying 65,000 victims who lost an estimated USD 300 million. The scammers lured victims into investing in cryptocurrency through extensive advertising campaigns promising high-yield returns. Victims were then instructed to download multiple apps to participate. Authorities arrested 15 individuals and seized key evidence including domains, mobile numbers and bank accounts. Investigations are ongoing with efforts focused on tracking down overseas collaborators.

Also in Zambia, authorities identified a scam centre and, in joint operations with the Immigration Department in Lusaka, disrupted a suspected human trafficking network. They confiscated 372 forged passports from seven countries.

Despite being one of the oldest-running internet frauds, inheritance scams continue to generate significant funds for criminal organizations. Officers in Côte d'Ivoire dismantled a transnational inheritance scam originating in Germany, arresting the primary suspect and seizing assets including electronics, jewellery, cash, vehicles and documents. With victims tricked into paying fees to claim fake inheritances, the scam caused an estimated USD 1.6 million in losses.

Valdecy Urquiza, Secretary General of INTERPOL, said:

"Each INTERPOL-coordinated operation builds on the last, deepening cooperation, increasing information sharing and developing investigative skills across member countries. With more contributions and shared expertise, the results keep growing in scale and impact. This global network is stronger than ever, delivering real outcomes and safeguarding victims."

Prior to the operation, investigators participated in a series of hands-on workshops covering open-source intelligence tools and techniques, cryptocurrency investigations and ransomware analysis. This focused training strengthened their skills and expertise, directly contributing to the effectiveness of the investigations and operational successes.

The operation also focused on prevention through a partnership with the International Cyber Offender Prevention Network (InterCOP), a consortium of law enforcement agencies from 36 countries dedicated to identifying and mitigating potential cybercriminal activity before it occurs. The InterCOP project is led by the Netherlands and aims to promote a proactive approach to tackling cybercrime.

Operation Serengeti 2.0 was held under the umbrella of the African Joint Operation against Cybercrime, funded by the United Kingdom’s Foreign, Commonwealth and Development Office.

Operational partners:
Cybercrime Atlas, Fortinet, Group-IB, Kaspersky, The Shadowserver Foundation, Team Cymru, Trend Micro, TRM Labs and Uppsala Security.

Participating countries:
Angola, Benin, Cameroon, Chad, Côte D’Ivoire, Democratic Republic of Congo, Gabon, Ghana, Kenya, Mauritius, Nigeria, Rwanda, Senegal, South Africa, Seychelles, Tanzania, United Kingdom, Zambia and Zimbabwe.

41 servers seized and 32 suspects arrested during Operation Secure.

More than 20,000 malicious IP addresses or domains linked to information stealers have been taken down in an INTERPOL-coordinated operation against cybercriminal infrastructure.

During Operation Secure (January – April 2025) law enforcement agencies from 26 countries worked to locate servers, map physical networks and execute targeted takedowns.

Ahead of the operation, INTERPOL cooperated with private-sector partners Group-IB, Kaspersky and Trend Micro to produce Cyber Activity Reports, sharing critical intelligence with cyber teams across Asia. These coordinated efforts resulted in the takedown of 79 per cent of identified suspicious IP addresses.

Participating countries reported the seizure of 41 servers and over 100 GB of data, as well as the arrest of 32 suspects linked to illegal cyber activities.

Infostealer malware is a primary tool for gaining unauthorized access to organizational networks. This type of malicious software extracts sensitive data from infected devices, often referred to as bots. The stolen information typically includes browser credentials, passwords, cookies, credit card details and cryptocurrency wallet data.

Additionally, logs harvested by infostealers are increasingly traded on the cybercriminal underground and are frequently used as a gateway for further attacks. These logs often enable initial access for ransomware deployments, data breaches, and cyber-enabled fraud schemes such as Business Email Compromise (BEC).

Following the operation, authorities notified over 216,000 victims and potential victims so they could take immediate action - such as changing passwords, freezing accounts, or removing unauthorized access.
Vietnamese police arrested 18 suspects, seizing devices from their homes and workplaces. The group's leader was found with over VND 300 million (USD 11,500) in cash, SIM cards and business registration documents, pointing to a scheme to open and sell corporate accounts.

As part of their respective enforcement efforts under Operation Secure, house raids were carried out by authorities in Sri Lanka and Nauru. These actions led to the arrest of 14 individuals - 12 in Sri Lanka and two in Nauru - as well as the identification of 40 victims.

The Hong Kong Police analysed over 1,700 pieces of intelligence provided by INTERPOL and identified 117 command-and-control servers hosted across 89 internet service providers. These servers were used by cybercriminals as central hubs to launch and manage malicious campaigns, including phishing, online fraud and social media scams.

Neal Jetton, INTERPOL’s Director of Cybercrime, said:

“INTERPOL continues to support practical, collaborative action against global cyber threats. Operation Secure has once again shown the power of intelligence sharing in disrupting malicious infrastructure and preventing large-scale harm to both individuals and businesses.”
