browser-based threat report: malware hosting

This URL was detected by ConcealBrowse on March 21st. One security vendor originally reported it in November of 2023, with 4 vendors reporting on it today. ConcealBrowse assigned the page a 14% risk assessment, citing suspicious behavior.

This page has been flagged by other security vendors as potentially hosting malware. Malware is most typically introduced to the victim via a Trojan, or a program that is designed to appear benign but holds malicious intent. In the cases of malicious adblockers, they usually cause more advertisements to appear, and could potentially track the victim’s browsing habits to be used for spam and further advertising campaigns. While there isn’t necessarily a risk to the victim’s accounts, it can cause a nuisance and is undesirable on company machines.

Conceal Recommends: Consider implementing company policies that prohibit the download of unauthorized software or extensions on company equipment. While in isolation, ConcealBrowse stops the download of any software hosted on the page.

browser-based threat report: microsoft phishing scam

This page was first detected by ConcealBrowse on March 25th, the same day that other security vendors began reporting. Only one vendor is reporting on this emerging threat. ConcealBrowse successfully intervened with a 51% risk score, citing proximity, phishing, and suspicious behavior.

Phishing pages from recognized brands, such as Microsoft, are becoming harder for the average user to detect. This page is seeking out specific email addresses and verifies that the input is correct before proceeding. This makes the page appear more legitimate and trustworthy to the victim. Because the site is in an isolated session, ConcealBrowse will still prevent any data from being entered by the user, keeping credentials secured.

Conceal Recommends: This URL should be blocked. ConcealBrowse’s live analysis is the best way to protect users against emerging threats such as this site.

browser-based threat report: browser notification scam

This URL was first detected by ConcealBrowse on March 25th, the same day that other security vendors began reporting it. It was initially detected by 11 vendors, and now 13 for phishing and malicious behavior. ConcealBrowse successfully intervened with a 28% risk score, citing suspicious activity, phishing, and malware.

Browser notification scams aim to trick the user into believing that they are solving a security puzzle, such as a Captcha, to proceed to their website. In reality, they are enabling browser notifications which will fill their machine with unwanted pop-ups and advertisements. These pop-ups can direct users to malicious pages and persist even if the original page that started the attack is closed.

Conceal Recommends: This URL should be blocked. ConcealBrowse’s intervention on this page would stop notifications from being pushed to the user’s actual browser.
