From Infostealer Log to Marketplace Listing: A Technical Walkthrough of the Credential Theft Pipeline
Cyble walkthrough maps how infostealer logs move from endpoint infection through aggregation and enrichment to dark web credential marketplace sales.
Cyble breaks the credential theft pipeline into stages: infostealer execution harvesting browser credential stores, cookies, session tokens, crypto wallets, and FTP configurations; aggregation of stealer logs via C2 panels into bundled archives; parsing and enrichment against previously leaked datasets; and final listing on dark web marketplaces. Enrichment adds employer and role context that raises prices and enables credential stuffing across reused passwords. The report advises SOC teams to monitor stealer logs and marketplace chatter early rather than waiting for breach alerts.

U.S. Bank says breach claims related to fourth
LockBit claimed data theft from U.S. Bancorp, but the bank attributes it to a fourth-party breach at a contractor's third party, with no impact on its own systems.
LockBit added U.S. Bancorp to its leak site and threatened to release stolen data within two weeks, but the bank investigated and attributed the claims to a fourth-party incident outside its environment. U.S. Bancorp stated there is no evidence its systems, networks, or data repositories were compromised and reported the matter to law enforcement. The bank is the seventh largest in the United States, and LockBit provided no samples to substantiate the claim. The gang, previously subject to a 2024 law enforcement takedown, earned $252.4 million in ransoms through 353 attacks from 2022 to 2024 according to the U.S. Treasury.

Muhstik Botnet Attacks Tomato Routers to Harvest New IoT Devices
Unit 42 found a Muhstik botnet variant brute-forcing Tomato router web authentication to harvest IoT devices for crypto mining and DDoS attacks.
Palo Alto Networks Unit 42 researchers in December 2019 identified a new Muhstik botnet variant scanning Tomato routers on TCP 8080 and brute-forcing default admin credentials, targeting roughly 4,600 exposed devices found via Shodan. The variant also scans WordPress and Webuzo installations and exploits the Oracle WebLogic deserialization flaw CVE-2019-2725 for unauthenticated remote code execution. Muhstik, active since March 2018, self-propagates like a worm and typically monetizes infections through cryptocurrency mining and DDoS attacks controlled via an IRC C2 channel.
