A surge of deceptive browser prompts has emerged around late June 2025, ensnaring visitors with fake CAPTCHA tests before demanding “Allow” clicks. A recent case on June 23, 2025 showed the site oveprotocol.co[.]in tricking users into consenting to unsolicited ads and redirects. What happens if one unknowingly grants permission? The result: a barrage of intrusive pop-ups, slowed browsing, and potential exposure to further threats.
Threat Overview
Ads by oveprotocol.co.in falls under browser hijacker/adware. It abuses legitimate web-notification features to deliver aggressive, sponsored content. Once enabled, these notifications can push links to scams, untrustworthy downloads, and even more malicious payloads.
In-Depth Analysis
Infection Vector
Users most often encounter oveprotocol.co[.]in through redirects on legitimate sites that have been compromised by rogue advertising networks. Upon landing, the site displays a counterfeit CAPTCHA, then instructs “Press ‘Allow’ to prove that you are not a robot,” thereby tricking visitors into granting notification permissions.
Behavioral Profile
- Initial Redirect – Visitor is sent from a seemingly benign page into oveprotocol.co[.]in.
- Fake CAPTCHA – A checkbox-style verification appears, promising to verify human status.
- Permission Request – Before completion, the page prompts the “Allow” button to enable notifications.
- Delivery of Ads – Once allowed, the browser accepts push notifications from oveprotocol.co[.]in, which then deliver continuous pop-up ads, redirects, and links to potentially harmful content.
Risk Assessment
Allowing oveprotocol.co[.]in notifications magnifies both privacy and security risks. Persistent ads can cloak phishing attempts or lure users into installing additional unwanted applications. In real-world incidents, similar notification-based campaigns have led to credential theft and drive-by downloads. Early removal keeps browsing safe and averts possible data loss.
