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.

Most Fraudulent Hires Receive Credentials Before Detection

HYPR report finds 42% of fraudulent hires pass screening and receive corporate credentials, averaging 5.73 days of unmonitored network access before detection.

A HYPR study of 500 US HR executives found 42% of fraudulent candidates pass pre-hire screening and get hired, with only 3% detected on their hire day and 20% remaining undetected up to three weeks. This gives fraudulent hires an average of 5.73 days of unmonitored corporate network access, and 98% of surveyed executives said they had experienced candidate fraud firsthand. The report follows a September 9 CISA update to its Insider Threat Mitigation Guide warning that malicious actors use AI tools to obtain remote IT jobs, a tactic long used by North Korean actors for data theft and extortion.

Hackers Use Blob URLs and Microsoft Teams to Create Phishing Pages Inside Victims’ Browsers

Barracuda details a phishing campaign using Microsoft Teams OAuth redirects and browser blob URLs to render local fake DocuSign login pages for credential theft.

Barracuda researchers identified an active phishing campaign that routes DocuSign-themed emails with calendar invites through a Microsoft OAuth endpoint and crafted redirects into Microsoft Teams, then renders a fake sign-in page via a browser-generated blob URL. Because the page is assembled locally in memory and can register service workers and run in a sandboxed iframe, URL-reputation checks largely see legitimate Microsoft domains. The goal is credential theft and account takeover, not a flaw in Teams itself.
