Social media, while a haven for entertainment and connection, can also be a breeding ground for cyber threats. Recently, a new malware called Ov3r_Stealer was discovered, specifically targeting unsuspecting users through Facebook advertisements. This malware aims to steal your cryptocurrency wallets, passwords, and other sensitive information, sending it straight to the attacker's hands.
How Does it Work?
The attack starts with a seemingly harmless Facebook ad, often mimicking job postings or featuring fake profiles of prominent figures. Clicking on these ads lead you to malicious links, disguised as PDF Files shared on OneDrive or application access pages. These links trigger the download of malicious files disguised as legitimate tools, like Windows Control Panel binaries.
Once downloaded, the malware silently installs itself on your system, using clever techniques like scheduled tasks to ensure it runs regularly in the background. It then begins its data harvesting, targeting a wide range of information, including:
Geolocation: Knowing your location provides valuable context for attackers.
Hardware information: This helps understand your system capabilities and potential vulnerabilities.
Passwords and cookies: The jackpot for attackers, granting access to your online accounts.
Credit card information and auto-fills: Financial details are highly sought after.
Browser extensions and crypto wallets: Specialized data for specific targets.
Office documents and antivirus information: Provides deeper insights into your system and potential defenses.
The Alarming Outcome:
All this stolen data ends up in a Telegram channel for bidding controlled by the attacker. It can be sold on the dark web, used for further attacks like ransomware, or employed to install even more malicious programs.
Staying Safe:
Protecting yourself from such threats requires vigilance and awareness:
Resist the Click Bait: Beware of clicking on random ads, even if they appear to come from legitimate sources.
Never save your passwords in your browser: Avoid saving them in your browser where they're vulnerable to theft.
Avoid saving Credit/Debit Card Details in Autofill: The ease of autofill can be tempting, but remember, convenience shouldn't trump security
Enable two-factor authentication: Add an extra layer of security to your accounts.
Keep software updated: Outdated software often has vulnerabilities that attackers can exploit.
Report suspicious activity: If you encounter anything suspicious, report it to Facebook and relevant authorities.
By staying informed and practicing safe online habits, you can significantly reduce the risk of falling victim to malicious scams like Ov3r_Stealer. Remember, your online security is in your hands!
