This web page was detected by ConcealBrowse on October 30th, 2023 with it first being submitted to CTI feeds on October 31st, 2023. This showcases Conceal’s ability to identify risky webpages in real time, even before CTI feeds report on them. This type of attack has been seen in several of Conceal’s customer environments.
The delivered page mimics the Yahoo home page by pulling legitimate assets such as images, an iFrame and even a script from Yahoo.com, which is not common practice. Any assets pulled from legitimate sites are mainly through their content delivery network. The adversaries spent a decent amount of time on crafting the page, which included 168 legitimate links leading to Yahoo. However, the page did have a high amount of empty and void links, which is indicative of phishing sites. Threat actors often do not have the time or ability to fully mimic web page functionality. With that, the site has been subsequently identified by 5 security vendors as a phishing site.
This currently active URL was detected by ConcealBrowse on October 25th, 2023. Although the webpage was first submitted to various CTI feeds October 31st, 2021, it was resubmitted the morning of October 31st, 2023, meaning the page continues to deliver suspicious content.
The webpage is a login page to a commoditized Phishing-as-a-Service (PhaaS) provider based out of Russia that has been operating since June 2021. As a purchasable nefarious phishing service, the page should not be trusted.
