Nigeria Arrests Developer Behind RaccoonO365 Phishing Attacks on Microsoft 365
In December 2025, Nigerian authorities arrested three high-profile cybercriminals, including the developer behind the notorious RaccoonO365 Phishing-as-a-Service (PhaaS) operation. RaccoonO365 enabled widespread Microsoft 365 phishing campaigns targeting large global corporations, facilitating credential theft and unauthorized access through sophisticated phishing kits and email lures. The Nigeria Police Force National Cybercrime Centre (NPF–NCCC) led the investigation, collaborating with international law enforcement agencies to dismantle core elements of the PhaaS infrastructure. The disruption has limited the proliferation of phishing tools contributing to corporate account compromises and subsequent business email compromise (BEC) incidents. This case underscores the persistent evolution and professionalization of phishing-as-a-service marketplaces, often operated across borders. It highlights an increased law enforcement focus on targeting not only the end-users but also the developers and operators of cybercriminal toolkits enabling downstream attacks.
