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.

Tajin Group: Guarantee Marketplace Vendor Involved in Phishing and Chinese Money Laundering Group

Recorded Future details Tajin Group, a Chinese-speaking vendor on Telegram guarantee marketplaces running phishing, carding, and money laundering operations targeting Chinese banks.

Insikt Group analyzed Tajin Group, a Chinese-speaking threat actor operating on Telegram-based guarantee marketplaces Dabai Guarantee and, since May 2026, Xinbi Guarantee. The group conducts phishing, payment card theft, and money laundering targeting mainland Chinese citizens and banks, testing stolen cards from twelve countries on platforms like CCAvenue and Geidea. Operators bought and sold at least 100 Telegram usernames and anonymous virtual numbers via Fragment Market to strengthen OPSEC, linking multiple usernames to single Telegram accounts. Recorded Future warns Tajin Group's TTPs are likely to be replicated by other vendors on Chinese-language guarantee marketplaces at global scale.

BraZetsu Malware Turns Compromised Windows Hosts Into Criminal Marketplace Inventory

Group-IB details BraZetsu, a modular Python Windows malware that monetizes compromised-host access through the Infected Marketplace for initial access brokers.

Group-IB attributes BraZetsu to the Exilware threat actor, believed to be native Portuguese speakers targeting Iberian and Latin American e-commerce, financial, industrial, and law enforcement victims. The framework, first observed in early May 2026, uses generative AI for data triage and target prioritization, steals browser histories and digital certificates, and hunts Brazilian CNAB financial remittance files. Access to compromised hosts is sold on the Infected Marketplace from roughly $5.80, letting buyers remotely deploy secondary payloads over WebSocket-linked infrastructure. Some samples evaded detection on VirusTotal; delivery likely uses VBS loaders from a domain also used to distribute the Ousaban banking trojan.

U.S. Disrupts Xinbi Guarantee Scam Marketplace, Freezes $52.8 Million in Crypto

US DOJ and Treasury disrupt Xinbi Guarantee Telegram scam marketplace, sanctioning it and freezing $52.8M in USDT across 52 wallets.

The DOJ seized Xinbi Guarantee's Telegram channels and cryptocurrency wallets while OFAC sanctioned the marketplace, freezing $52.8 million in USDT from 52 wallets and bringing the Scam Center Strike Force's total restrained funds to roughly $938 million. Elliptic, which worked with the Secret Service, estimates Xinbi has processed $30 billion in transactions since around 2022, serving pig-butchering scam operators and links to North Korean hackers, Jin Bei Group, and Prince Group TCO. The strike force dismantled 13 scam compounds in Madagascar, seizing over 3,200 devices and interviewing roughly 400 arrestees, with about 30 Chinese compound leaders repatriated to China. After Tether froze funds, Xinbi began converting remaining USDT into the USDD stablecoin.
