Evil Stealer is a newly identified cybercrime operation centered on an information-stealer malware-as-a-service offering. The operation has been assessed as combining at least three monetization streams: credential-log processing at significant scale, a cryptocurrency wallet-draining component embedded in its web panel, and a linked automated scraper branded OFM Hub Intel that targets OnlyFans creators, particularly female performers. Reporting tied the operation to more than 310,000 processed credential logs, although the exposed counter may reflect migrated historical data rather than only fresh infections. The actor demonstrated poor operational security that enabled unusually strong attribution clues. Embedded metadata in a promotional video exposed a Windows username, Russian-language keyboard artifacts, and timestamps consistent with UTC+3, supporting an assessment that the operator is likely a Russian-speaking individual working on Moscow time. The infrastructure was rapidly deployed in early March 2026 and exposed multiple misconfigurations, including a raw Next.js application server and an unauthenticated Python status API that disclosed internal operational details. Evil Stealer appears to be in active development, with the panel advertising a pre-release version and some advertised functionality not yet operational. The exact malware payload and delivery mechanism were not publicly identified, and the external exfiltration channel remained unclear. Nevertheless, the operation clearly supports credential theft and data collection workflows, and its panel code indicates an attempt to induce cryptocurrency wallet connections for theft. The linked OFM Hub Intel service further shows diversification into scraping and monetizing creator data. Known aliases associated with the operation include evil_stealer and evil_stealer_operator. OFM Hub Intel is best understood as a related service or sub-operation operated by the same actor rather than a separate threat group. Overall, Evil Stealer is best characterized as a financially motivated Russian-speaking cybercrime actor running an emerging MaaS ecosystem with credential-theft, crypto-theft, and data-harvesting components.
