Nowy wariant metody ClickFix – cyberprzestępcy rezygnują z Win+R na rzecz Win+X i Terminala Windows

Badacze bezpieczeństwa z Microsoft Defender ostrzegają przed nowym wariantem kampanii malware, w której cyberprzestępcy za pomocą phishingu nakłaniają użytkowników do instalacji złośliwego oprogramowania typu infostealer (Lumma Stealer). Atak opiera się na technice ClickFix, polegającej na przekonaniu użytkownika do uruchomienia złośliwych poleceń PowerShell.TLDR: Schemat ataku jest dosyć prosty. Korzystając z socjotechniki...

CTM360 identifies an active campaign leveraging Google Groups and Google-hosted redirect chains to deliver Lumma Stealer (Windows) and a trojanized Chromium fork branded “Ninja Browser” (Linux).
Technical highlights:
• 950MB padded executable (null-byte inflation)
• AutoIt loader reconstruction
• Memory-resident payload execution
• Multipart/form-data POST exfiltration
• Malicious extension “NinjaBrowserMonetisation”
• XOR + Base56-like JS obfuscation
• Scheduled task persistence
• Russian search engine default modification

This campaign reinforces a critical shift: SaaS platforms are now delivery infrastructure.
Defensive priorities:
– IoC blocking at firewall + EDR
– Redirect chain inspection
– Extension audit controls
– Endpoint scheduled task monitoring

DNS-based staging via ClickFix represents tactical evolution.

Per Microsoft:
• Cmd.exe → nslookup execution
• Hardcoded external DNS resolver
• Payload embedded in DNS Name: response
• ZIP retrieval from azwsappdev[.]com
• Python-based reconnaissance
• VBScript persistence via Startup LNK
• ModeloRAT deployment
• Lumma Stealer distribution via CastleLoader (GrayBravo)

Campaign telemetry also discussed by Bitdefender and Kaspersky.

DNS offers:
• Reduced dependency on HTTP
• Traffic blending with legitimate queries
• Lightweight validation signaling

Detection priorities:
• Anomalous nslookup patterns
• External DNS resolver usage
• Suspicious Startup LNK creation
• DNS response content inspection

Is your EDR correlating DNS queries with process lineage?

It's been a busy 24 hours in the cyber world with significant updates on the evolving "ClickFix" social engineering tactic, showing how attackers are getting creative with initial access and payload delivery. Let's take a look:

Evolving ClickFix Attacks: DNS Staging and Crypto Hijacks ⚠️

- Microsoft has detailed a new DNS-based ClickFix variant where victims are tricked into running `nslookup` commands, using DNS as a stealthy staging channel for payloads like ModeloRAT. This method blends malicious activity into normal network traffic, making detection harder.
- A separate, novel ClickFix campaign is leveraging Pastebin comments and Google Docs to socially engineer cryptocurrency users into executing malicious JavaScript directly in their browser. This allows attackers to hijack Bitcoin swap transactions and redirect funds to their wallets.
- These incidents highlight the evolving nature of ClickFix, moving beyond traditional OS-level command execution to sophisticated DNS staging and direct browser manipulation for financial theft, underscoring the critical need for user awareness and robust detection of procedural trust abuse.
