Warning: DarkCloud is a stealthy infostealer that quietly infiltrates your system and exfiltrates sensitive data—don’t wait to act.
Threat Overview
DarkCloud Stealer is a trojan-infostealer first detected in 2022. It uses highly obfuscated, multi-stage infection techniques—spanning phishing emails, archives (RAR, TAR, 7Z), JavaScript or Windows Script File (WSF), PowerShell execution, and process hollowing—to sneak past defenses and inject a final payload that steals credentials, files, and financial data. The malware exfiltrates information using methods like SMTP, FTP, or Telegram Web Panels.

How Did I Get Infected With DarkCloud Stealer?
Infection typically begins with malspam—emails containing RAR, TAR, or 7Z archives labeled as invoices, updates, or quotes. These archives include JavaScript (JS) or WSF scripts. When executed, they pull a PowerShell (PS1) script from a remote source, which drops and runs the DarkCloud executable. The infection chain is heavily obfuscated, often using tools like ConfuserEx and sometimes AutoIt, making it hard to detect.
What DarkCloud Stealer Does to Your System
Once inside, the stealer performs extensive data harvesting:
- Captures credentials, browser data, credit card info, cookies, and screenshots.
- Scours files (TXT, XLS, PDF) and accesses applications such as VPNs, messengers, FTP clients, crypto wallets, and email contacts.
- Exfiltrates stolen content using SMTP, FTP, or Telegram channels.
Should You Be Worried About DarkCloud Stealer?
Absolutely. DarkCloud is actively evolving, with increasingly sophisticated obfuscation (ConfuserEx, AutoIt), stealth tactics (process hollowing), and fileless execution. It targets sensitive information with severe consequences: identity theft, financial fraud, or network compromise.
