Last year, 1.7 million removals of extremist content were actioned by online platforms under the EU Digital Services framework, yet the underlying networks that spread violence still leave measurable traces across attacks, finance, and sanctions. From killings in OECD states tied to the full spectrum of terrorism to resource flows and cross border charity misuse, the pattern is more systematic than headlines suggest. The dataset also captures how quickly ISIS linked accounts can be deactivated while its affiliates keep finding new channels, turning “disruption” into a moving target.
Key Takeaways
- 4,919 people were killed in terrorism attacks in the OECD area in 2022 (includes attacks by all terrorist groups, not only Islamist), indicating 2022 as the deadliest year in the dataset since 2016
- 1,000+ terrorist attacks/attempts in Afghanistan attributed to ISIL/ISIS affiliates across multiple years (dataset figure used in reporting by UN sanctions/monitoring mechanisms)
- ISIS-K conducted a significant spike in attack capability in 2021–2023; the UN documented at least 1,000 attacks/attempts across multiple years in Afghanistan linked to ISIL/ISIS affiliates in its reporting
- Al-Shabaab was responsible for multiple high-casualty attacks in Somalia; the UN Monitoring Group reported 2022 as a year with sustained high activity by ISIL-aligned affiliates
- Boko Haram/ISWAP activity continued in Nigeria and the Lake Chad Basin; UN reports documented hundreds of attacks per year (group-activity tallies in monitoring reports)
- The FATF reported that the laundering risks related to terrorist financing are elevated for certain sectors; the agency’s Terrorist Financing report quantifies key typologies and case patterns across the global TF ecosystem
- FATF has repeatedly reported that terrorist financing typologies often involve misuse of charitable/non-profit organizations; the FATF study on charities provides quantified findings on misuse cases in multiple jurisdictions
- $7.3 billion to $10.8 billion per year in terrorist financing flows globally is estimated in the widely cited FATF assessment of terrorist financing resource needs (global estimate range)
- The UN Security Council sanctions framework for ISIL/Al-Qaeda has 200+ designated individuals and entities (as counted in the consolidated list) under the relevant sanctions regimes
- FATF’s mutual evaluation reports quantify effectiveness ratings for counter-terrorist financing controls by country; the FATF database provides counts of ratings (e.g., the number rated as “moderate/large extent” for TF measures)
- UN Security Council resolutions on countering terrorism financing include quantified compliance reporting requirements; the resolution text mandates specific reporting cycles with defined deadlines
- The UNODC data portal reports thousands of tracked terrorist incidents in its datasets (counts by year and region; used in trend charts across illicit markets supporting terrorism)
- Google Transparency Report documents takedown volume for terrorist content removal requests under applicable policies, with quantified quarterly counts (e.g., number of removals in a reported period)
- Microsoft’s Digital Safety reports show quantified enforcement actions against terrorist content, including number of actions and takedown outcomes in reported periods
- 72% of terrorist financing case examples in the FATF report ‘Terrorist Financing in the Charities Sector’ involve risks related to cross-border transfers (share of case examples by risk factor)
In 2022, terrorism deaths surged in the OECD while global financing and online extremist activity risks increased.
