ConcealBrowse is leveraged by teams across the world to combat weaponized URLs. The technology is constantly analyzing suspicious web artifacts to identify risks in the form of drive-by attacks, phishing portals, and other threats that materialize while browsing.

At Conceal, your digital safety is our utmost priority. Our weekly threat report for the week of April 8th, 2024, unveils critical insights into the ever-evolving landscape of online threats.

The following report highlights recently detected sites that were deemed suspicious:



browser-based threat report 4.8.24

This page was detected by ConcealBrowse on April 4th, with security vendors first flagging the site in early March. The URL originally received hits from 9 security vendors and is now detected by 17 for phishing. ConcealBrowse intervened with a 29% risk assessment because of suspicious behavior.

This page attempts to steal Microsoft credentials by impersonating the Sharepoint login page. Phishing pages like this one have become more sophisticated by verifying that the email address entered is legitimate before proceeding to the password phase of the attack. ConcealBrowse’s intervention prevents users from entering credentials while in an isolation session.

Conceal Recommends: Due to the nature of the activity on this page, it is recommended to block both the URL and IP address associated with this site.

browser-based threat report 4.8.24

This URL was first seen by ConcealBrowse on April 4th, with the first security vendors reporting the site as malicious in March. It is currently detected by 11 vendors for malicious behavior and distributing malware. ConcealBrowse intervened with a 14% risk assessment due to suspicious behavior.

This page utilizes evasion techniques that cause the site to be inaccessible to most browsers. When being accessed by the target browser, it is being used to distribute a software known for browser hijacking. Browser hijacking occurs when a malicious download, typically a browser extension, causes unwanted redirects and changes to the victim’s settings, such as the home page. This can lead to excessive advertisements, violations of data privacy, and be a nuisance to the victim.

Conceal Recommends: This URL should be blocked to prevent access. While in an isolated session, users cannot download any harmful programs onto their machine. Although the site is not accessible on all browsers, ConcealBrowse continues to detect and defend against it.

browser-based threat report 4.8.24

This site was first detected by ConcealBrowse on April 5th, the same day other security vendors began reporting. It was initially flagged by one vendor and has now been detected by two for potential phishing activity. ConcealBrowse successfully intervened with a 14% risk assessment, citing suspicious behavior.

This URL is considered an emerging threat, with the domain being registered one day before the site began appearing on threat feeds. Credential harvesting typically happens quickly through targeted attacks, and with links that become stale within a few days of being generated. This is why live-threat analysis provided by ConcealBrowse is critical to protecting end-users.

Conceal Recommends: This URL and IP address should be blocked. ConcealBrowse prevents keyboard input while in an isolated session.
