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.

Credentialed Pre-Port Discovery: Don't Probe the Host, Ask it

Rapid7's version 8.58 adds credentialed pre-port discovery, letting scan engines query hosts for listening TCP/UDP ports instead of network probing.

Rapid7 documents credentialed pre-port discovery, available from version 8.58 as an off-by-default per-template option under Asset Discovery. The scan engine authenticates with existing SSH, Scan Assistant, or Windows credentials and receives the host's authoritative list of listening TCP and UDP ports, skipping the network port scan. Hosts without matching credentials silently fall back to network port scanning. Trade-offs include reporting firewall-blocked ports the engine cannot reach, longer scans, and early termination findings caused by repeated connection failures.
