The Fraud Ecosystem: A Transition From Known Marketplaces to a Fragmented Environment
Rapid7 analyzes how fraud marketplaces are fragmenting into specialized shops after larger marketplaces were dismantled, aided by new MITRE F3 framework
Rapid7 reports a shift from large known fraud marketplaces to a fragmented environment of smaller specialized storefronts such as Xleet, Blackpass, Infodig, and Styx, operating across dark web channels, Telegram, and P2P options. These Fraud-as-a-Service shops sell stolen accounts, PII, synthetic identity generation, infrastructure, and money laundering support, supporting schemes like business email compromise. MITRE's Fraud Fighting Framework (F3), introduced in early 2026, aims to help security teams prioritize monitoring of fraud TTPs, particularly account takeover techniques. Fraud damages are anticipated to approach hundreds of billions of USD.

Unauthenticated RCE Flaws Could Expose 200,000+ WordPress Sites to Takeover
Two unauthenticated CVSS 9.8 code-injection and PHP object injection flaws in The Events Calendar plugin expose 200,000+ WordPress sites to RCE and takeover.
Defiant identified two critical vulnerabilities in The Events Calendar WordPress plugin, which has over 600,000 active installations. CVE-2026-78159, unauthenticated code injection during single-event HTML processing, was patched in version 6.17.3.1 on August 25; CVE-2026-78006, unauthenticated PHP object injection via event comments, was patched in 6.17.4.1 on September 10. Both independent chains lead to remote code execution and full site compromise. Roughly 240,000 sites run versions vulnerable to both flaws, and about 300,000 downloads between September 10 and 14 suggest half of installations may still lack the second fix.

Risky Bulletin: Dutch intel services to get extensive new powers
Netherlands proposed a bill granting AIVD and MIVD expanded warrantless tapping, faster hacking powers, and forced data disclosure, citing Russia, China, and Iran threats.
The Dutch government introduced a bill greatly expanding surveillance powers of intelligence agencies AIVD and MIVD, allowing up to one year of tapping without pre-approval and simplified hacking operations against 'foreign adversaries'. Agencies could compel Dutch companies or citizens to provide data under threat of charges, share data with the private sector, and oversight bodies would merge into a new CTT board. The bill follows similar overhauls in Ireland, Germany, and France after Russia's invasion of Ukraine.
