DOUBLECUP's Stealthy Malware Delivery via ClickFix and Steganography
In August 2026, a Russian Loader-as-a-Service (LaaS) named DOUBLECUP was identified utilizing ClickFix lures to embed steganographic PNG images into victims' browser caches. This method facilitated the delivery of CountLoader and a new remote access trojan, DeviceManager. The attack sequence involved dropping a PNG image into the browser cache, extracting hidden content, and executing a second-stage payload that decrypted the final malware using the victim's public IP address as a cryptographic key. DeviceManager employed EtherHiding to resolve its command-and-control infrastructure, communicating over HTTP or DNS tunneling. The DOUBLECUP service, active since June 2026, provided operators with licenses and client agents to create campaigns by embedding code into ClickFix landing pages. Each license included metadata such as the client's IP address, active days, label, and version, allowing multiple campaigns per license. The service also featured a Windows GUI client for configuration updates and command issuance. Campaigns leveraging DOUBLECUP impersonated CRM login pages, including NetSuite, Odoo, HubSpot, and Salesforce, to deliver the loader via embedded iframe elements. This approach led to the execution of ClickFix commands that searched the browser cache for the PNG image, extracted malicious scripts, and launched subsequent payloads. The attack chain concluded with the stager reconstructing and executing the final payload, establishing persistence, and exfiltrating system metadata. The emergence of DOUBLECUP underscores the evolving sophistication of cyber threats, particularly the use of steganography and environmental keying to evade detection. The integration of ClickFix lures with advanced payload delivery mechanisms highlights the need for enhanced security measures and user awareness to mitigate such threats.
