In-Depth Analysis

Infection Vector

Surilour.co.in typically infiltrates through:

• Deceptive websites: Adult content, free streaming, or illegal download sites often display fake alerts urging users to “Allow notifications to continue.”
• Bundled software: Freeware downloads may silently change browser settings or open malicious tabs.
• Malicious advertisements: Clicking on rogue ads can lead directly to Surilour.co.in’s push notification request.

Behavioral Profile

Step by step, the attack unfolds:

1. Initial Contact: A user lands on a compromised or intentionally malicious webpage.
2. Deceptive Prompt: The site immediately displays a fake system message—often claiming a required CAPTCHA, video access, or urgent security update—and asks to “Allow notifications.”
3. Permission Abuse: If the user consents, Surilour.co.in gains browser-level permission to send notifications.
4. Notification Spam: Aggressive ads begin to appear even when the browser is closed, typically promoting scams, tech support fraud, or additional malware.
5. Redirection & Escalation: Clicking these notifications can lead to phishing pages, unwanted downloads, or even further hijackers.
6. Persistence Mechanism: The hijacker may alter homepage or search settings, install dubious browser extensions, or resist easy removal.

Risk Assessment

• Privacy Threat: Frequent pop-ups often carry tracking scripts, logging user activity across the web.
• Financial Risk: Some notifications lead directly to phishing pages or fake sweepstakes, harvesting credentials or payment data.
• System Integrity: If additional malware is downloaded, the risk escalates to credential theft, ransomware, or even full system compromise.
• Real-world Example: During the 2020 spike in push notification abuse, several high-profile adware campaigns were linked to credential theft and ransomware dropper infections after victims allowed rogue notifications.
