Infostealers highlight malware-as-a-service trend
ReversingLabs identified three active infostealer malware-as-a-service families: AuraStealer, ACRStealer/Amatera, and RemusStealer, with 1,110 unique samples observed between June and August 2026. RemusStealer distinguishes itself through Etherhiding, using Ethereum smart contracts for C2 domain resolution. AuraStealer adopted virtualization-based obfuscation, increasing its file size from 500-700KB to 10MB. All three families target browser credentials and crypto wallets, distributed via ClickFix, ClearFake, SEO poisoning, and malvertising.

What Happened
Criminals are renting ready-made malware called infostealers to steal passwords, cryptocurrency wallets, and other sensitive data from computers. Three specific malware families were identified as particularly active: AuraStealer, ACRStealer, and RemusStealer, with over a thousand unique samples found between June and August 2026. These programs spread through fake website verification prompts, manipulated search engine results, and malicious advertisements. Anyone who browses the web or manages cryptocurrency on a computer could be affected. The stolen data gives criminals access to bank accounts, email, and other important services. Individuals and organizations should verify website authenticity, avoid running commands from untrusted sources, and use security software to detect these threats.
Key Takeaways
- Three active infostealer MaaS families identified: AuraStealer, ACRStealer/Amatera, and RemusStealer with 1,110 unique samples combined between June and August 2026
- RemusStealer uses Etherhiding via Ethereum smart contracts for C2 domain resolution, making C2 traffic harder to detect and block through traditional network controls
- AuraStealer adopted virtualization-based obfuscation in summer 2026, increasing file size from 500-700KB to 10MB to evade analysis
- Distribution methods include ClickFix, ClearFake, SEO poisoning, malvertising, and malicious short form videos on social media
- All three families target browser credentials and crypto wallets, with ties to CIS countries and Russian language hacking forums
Affected Systems
- Windows systems (implied by .exe payloads and process injection techniques)
- Web browsers (credential and cookie theft)
- Cryptocurrency wallet applications
- Organizations in healthcare, financial, government, MSP, and tech sectors (RemusStealer targeting)
Vulnerabilities (CVEs)
None identified.
Attack Chain
- Initial Access: Social engineering via ClickFix, ClearFake, SEO poisoning, or malvertising tricks victim into downloading malware
- Execution: Victim runs malicious payload, often through fake reCAPTCHA verification or clipboard injection via JavaScript
- Defense Evasion: Malware uses virtualization (AuraStealer), VMProtect (Remus), string obfuscation, and anti-analysis checks to avoid detection
- Credential Access: Infostealer harvests credentials from browsers, crypto wallets, session tokens, and application data
- C2 Communication: RemusStealer uses Ethereum smart contracts (Etherhiding) for C2 domain resolution; AuraStealer and ACRStealer use traditional C2 domains
- Exfiltration: Collected data exfiltrated to attacker-controlled C2 servers
Detection Availability
- YARA Rules: No
- Sigma Rules: No
- Snort/Suricata Rules: No
- KQL Queries: No
- Splunk SPL Queries: No
- EQL Queries: No
- Other Detection Logic: No
The article does not provide any detection rules, queries, or signatures. It provides IOCs including file hashes, C2 domains, URLs, and IP addresses that can be used to build custom detections.
Detection Engineering Assessment
| Dimension | Rating | Rationale |
|---|---|---|
| EDR Visibility | Medium | Process injection and virtualization can be detected by EDR but anti-analysis features and VMProtect packing may cause some tools to miss samples. AuraStealer's virtualization increases file size to 10MB which may trigger some heuristics. |
| Network Visibility | Medium | C2 domains and URLs are listed with non-standard ports but Etherhiding via Ethereum smart contracts makes RemusStealer C2 harder to detect through traditional network monitoring. DNS queries to blockchain API endpoints may not be flagged. |
| Detection Difficulty | Moderate | IOCs are available across all three families but evasion techniques including virtualization, VMProtect packing, and Etherhiding increase detection difficulty. Non-standard C2 ports and blockchain-based C2 resolution require non-traditional detection approaches. |
Required Log Sources
- EDR process telemetry
- DNS resolution logs
- Web proxy logs
- Firewall logs with destination port information
- Browser security extension logs
Hunting Hypotheses
| Hypothesis | Telemetry | ATT&CK Stage | FP Risk |
|---|---|---|---|
| Processes accessing browser credential stores and crypto wallet application data directories may indicate infostealer activity | EDR process telemetry showing file access patterns to browser data directories | Credential Access | Medium - legitimate password managers and browser extensions also access these locations |
| Network connections to domains on non-standard high ports may indicate infostealer C2 communication | Firewall logs and proxy logs showing destination ports and domain resolution | Command and Control | Medium - some legitimate services use non-standard ports |
| Large executable files exceeding 10MB with virtualization or packing characteristics may indicate AuraStealer samples | EDR file creation events with size and entropy analysis | Defense Evasion | Low - 10MB executables with high entropy are uncommon in typical environments |
| Processes making DNS queries to Ethereum blockchain API endpoints followed by connections to dynamically resolved domains may indicate Etherhiding C2 | DNS logs and network flow data showing blockchain API queries preceding new domain connections | Command and Control | Low - blockchain API queries from non-cryptocurrency applications are unusual |
| Clipboard modification events triggered by JavaScript or browser processes may indicate ClearFake social engineering | EDR clipboard monitoring and browser process telemetry | Execution | Medium - legitimate clipboard managers and browser extensions modify clipboard contents |
Control Gaps
- Signature-based antivirus may miss virtualized or VMProtect-packed samples
- Traditional network controls may not detect Etherhiding C2 communication via Ethereum smart contracts
- DNS filtering may not catch dynamically resolved C2 domains from blockchain infrastructure
- Browser-based security controls may not detect credential theft from local browser stores
- Network firewalls may not block C2 traffic on non-standard high ports without explicit rules
Key Behavioral Indicators
- Processes accessing browser credential storage locations (T1555.003)
- Network connections to domains on non-standard high ports (T1071)
- Large executable files with virtualization or packing signatures (T1027.002)
- DNS queries to blockchain API endpoints followed by new domain connections
- Clipboard modification events triggered by JavaScript (T1059.001)
- Process injection and hollowing behavior patterns (T1055.012)
- Prompt boxes requesting randomized string input before execution, indicating anti-analysis checks
False Positive Assessment
Medium - C2 domains use common TLDs and non-standard ports that may overlap with legitimate services. Browser credential access by legitimate password managers could trigger false positives. Clipboard modification by legitimate browser extensions is common. Some C2 domain names resemble legitimate software tooling domains.
Recommendations
Immediate Mitigation
- Verify against your organization's incident response runbook and team escalation paths before acting. Consider blocking the listed C2 domains and download server IPs at network perimeter controls if supported by your infrastructure.
- Consider adding the provided file hashes to endpoint detection blocklists if your EDR or AV solution supports custom hash-based blocking.
- If your web proxy supports URL filtering, consider blocking the listed download URLs and C2 URLs, particularly those using non-standard ports.
Infrastructure Hardening
- Evaluate whether DNS filtering can block queries to the listed C2 domains and their associated TLDs (.cfd, .cc, .shop, .biz, .click, .surf, .courses, .garden).
- Consider implementing network rules to block outbound connections on non-standard high ports used by RemusStealer C2 servers.
- If applicable, evaluate whether blockchain API endpoints used for Etherhiding can be monitored or restricted on your network.
User Protection
- Consider deploying browser security extensions that alert on credential access by untrusted processes.
- Evaluate whether endpoint controls can detect and block clipboard modification by JavaScript or untrusted applications.
- If supported by your EDR, consider enabling behavioral detection for process injection and hollowing techniques.
Security Awareness
- Consider incorporating ClickFix and ClearFake social engineering techniques into existing security awareness training programs.
- Educate users on verifying website authenticity and avoiding fake reCAPTCHA verification prompts that request command execution.
- Consider advising users to be cautious of software downloads from search engine results, particularly for tools related to software development.
