The Silent Invader: How Hackers Use Windows Run Prompt to Spread DeerStealer

Once upon a time, in the vast digital landscape, cybercriminals lurked in the shadows, always searching for new ways to sneak into unsuspecting victims' computers. Their latest trick? A seemingly harmless tool we all use every day the Windows Run Prompt.

The Deceptive Shortcut

You know the Run Prompt that little box that pops up when you press Win + R. It’s meant to help you quickly open programs, but hackers have turned it into a weapon. By disguising malicious commands as innocent-looking instructions, they can silently execute harmful scripts, bypassing security measures like a thief slipping through an unlocked window.

Here’ show the story goes:

1. The Bait: A victim receives a phishing email or visits a malicious website.
2. The Trick: The attacker convinces them to press Win + R and paste a command (like a PowerShell script or a remote download link).
3. The Payload: The command runs silently, fetching DeerStealer a sneaky malware that steals passwords, cookies, and even cryptocurrency wallets.
4. The Aftermath: Before the victim realizes it, their data is gone, and the attacker vanishes into the dark web.

Why This Is Dangerous

• No Files Needed: The attack runs directly in memory, leaving little trace.
• Bypasses Defenses: Traditional antivirus may miss it since it abuses a trusted Windows feature.
• Silent & Deadly: DeerStealer operates quietly, exfiltrating data without alerting the user.
