Microsoft tech support scam

This URL was first detected by ConcealBrowse on February 21st; the same day other security vendors started reporting on it. Initially, only five security vendors marked the page as malicious, but currently there are 15 vendors flagging the page. ConcealBrowse successfully intervened with a 28% risk assessment due to suspicious activity.

When ConcealBrowse first intervened, this page was a Microsoft tech support scam. Malicious actors utilize Azure’s web application services to create Microsoft-branded pages that appear trustworthy. Although the page has since been removed from Microsoft, ConcealBrowse caught the malicious behavior prior to Microsoft intervening. Users are protected in real-time even before the owners of the domain can respond to reports of platform abuse.

Conceal Recommendation: Sites like these can be tricky to detect early, due to their trusted domain names and IP addresses to evade filtering technologies. Live analysis through ConcealBrowse is the best way to protect users in these scenarios.

This URL was first detected by ConcealBrowse on February 23rd and is not yet reported by any other security vendors. The page was given a 30% risk assessment, with ConcealBrowse citing possible phishing and malware.

This webpage has multiple indicators of selling an illegitimate product. Although this site may give the user a valid product key for Windows products, these keys are usually procured illegitimately and can be revoked at any point. Therefore, it is not safe to purchase keys from sites such as these, as doing so may cause interruptions in business flow and result in financial loss for the user.

Conceal Recommendation: This site should be considered an emerging threat and has not existed long enough for other security vendors to do a full analysis and publish their findings. Real-time analysis through ConcealBrowse detects novel techniques used by adversaries in order to disrupt these threats.

This URL was first detected by ConcealBrowse on February 20th. 10 security vendors flagged the page on that same date, with currently 9 reporting the page for spyware and phishing activity. ConcealBrowse successfully intervened, giving the page a 28% risk score and blocking the page from user access.

This website redirects to multiple different pages, most of which are involved in prize scams. Prize scams tell the victim that they have won, or have the potential to win, a large amount of money. The page asks for personal information such as their phone number and email address. This information can then be used to steal more information or create more personalized attacks. Due to the level of malicious activity detected, ConcealBrowse intervened to block the page rather than put it into isolation, preventing users from entering their information or viewing the site.

Conceal Recommendation: Balance out your defense-in-depth strategy to proactively detect suspicious web pages with technologies like ConcealBrowse that provide real-time analysis.
