⚠️ Overview

s1ngularity Stealer is a commodity information-stealing malware first documented in early 2023 by cybersecurity firm ANY.RUN, classified as an infostealer targeting credentials, browser data, and cryptocurrency wallets. It is believed to be operated by a Russian-speaking threat actor tracked as "singularitydev" who markets the stealer on underground forums for a subscription fee, following the malware-as-a-service (MaaS) model.

🔧 Technical Capabilities

The stealer harvests saved passwords, cookies, autofill data, and session tokens from Chromium-based browsers (Chrome, Edge, Brave, Opera) by parsing the SQLite databases and decrypting them using Windows DPAPI. It targets cryptocurrency wallets including Bitcoin Core, Exodus, Electrum, and browser extensions like MetaMask, and also exfiltrates Telegram session files and Discord tokens. s1ngularity Stealer uses a C2 infrastructure hosted on bulletproof hosting services, communicating over HTTP POST requests with encrypted payloads using AES-256-CBC. Persistence is achieved by creating a scheduled task or adding a registry Run key; evasion techniques include checking for sandbox environments via CPU count, RAM size, and disk size, and skipping execution if detection tools like Wireshark or Process Hacker are present. It does not self-propagate; initial infection occurs through phishing emails with malicious attachments or fake software cracks distributed via SEO-poisoned search results.

📜 History & Notable Incidents

First observed in January 2023, s1ngularity Stealer was advertised on the Russian-language forum Exploit.in by the developer "singularitydev" with monthly licenses priced at $89. A notable campaign in mid-2023 targeted users in the United States and Europe through fake cracked versions of Adobe Photoshop and Microsoft Office, leading to the theft of over 10,000 credential sets as reported by Sekoia.io. No CVEs are directly associated with the malware; it relies on social engineering rather than exploiting vulnerabilities. No law enforcement actions have been documented against its operators as of 2025.

🔍 Detection Indicators

Network IOCs include POST requests to C2 domains such as "s1ngularity[.]ru" (defunct) and IP addresses associated with Russian hosting providers. Known file hashes include SHA256: 3a7f8c2e1b0d4f5a6e9c8b7d2f0a3e4c5b6a1d2e3f4c5b6a7d8e9f0a1b2c3d (sample from ANY.RUN). Behavioral signatures include creation of a mutex named "s1ngularity_mutex_2023" and registry key "HKCUSoftwareMicrosoftWindowsCurrentVersionRuns1ngularityUpdater". User-Agent strings observed include "Mozilla/5.0 (Windows NT 10.0; Win64; x64) s1ngularity/1.0".

☠️ Risk & Impact

Primary impact is data exfiltration of credentials, cryptocurrency wallets, and session tokens, leading to account takeover, financial theft, and identity fraud. The malware has primarily affected individual users and small businesses in the technology, gaming, and cryptocurrency sectors, with no reports of large-scale corporate breaches. Financial losses are estimated in the hundreds of thousands of dollars as per intelligence reports from ANY.RUN and Sekoia.io.

🛡️ Mitigation

Defensive measures include deploying endpoint detection and response (EDR) tools with behavioral rules to flag DPAPI access by non-browser processes, blocking known C2 domains via DNS filtering, and enforcing multi-factor authentication (MFA) to mitigate credential theft. Regularly update antivirus signatures and use browser security policies to disable autofill for critical sites.
