The View from Across the Fraud Attack Chain | Global Anti-Scam Summit London 2025

Date of Event: 26–27 March 2025
Event: Global Anti-Scam Summit London 2025
This workshop provided a rare, full-spectrum view of how scams unfold across the fraud attack chain—from infrastructure and identity to engagement and execution.
Rima Amin of Meta introduced the session with a breakdown of how threat actors move across platforms to engage victims. She detailed Meta’s efforts to slow down scammers using behavioural signals, throttled messaging, and the FIRE programme, which brings banks into the reporting process to improve scam takedowns.
Valeriya Greene of Mastercard covered the execution phase, where scams culminate in payments. She explained that banks often have just seconds to assess risk, and with limited data on recipients, decision-making is extremely difficult. Greene urged wider use of consortium-level and network intelligence to improve risk detection.
Sandra Peaston of Cifas focused on identity and money mules. She discussed the importance of onboarding checks, fraud monitoring, and real-time intelligence sharing. She also shared details of a UK initiative to help banks protect individuals who are known to be at high risk of scams.
Mark Robertshaw from the DNS Research Federation highlighted weaknesses in the infrastructure phase. His research revealed that most phishing domains remain active far longer than the 24-hour scam cycle. He called for shorter takedown times, registry accountability, and earlier detection.
Jen V. concluded the session with reflections from the National Crime Agency. She stressed the value of fast collaboration, data sharing based on suspicion (not just confirmation), and targeted pilots to raise the cost of fraud and close gaps across the ecosystem.
