Detect Post Domain Transfer Threats | Case Study by HUB 53

Malicious actors are constantly on the lookout for new ways to run different scams or promote harmful content. One such way is to purchase previously owned domains without a bad history. Once up for sale, these seemingly ‘safe’ domains are acquired and then used to pass themselves off as legitimate businesses (brand impersonation), to drive traffic to websites with illegal or harmful content (SEO manipulation), or to trick users into divulging personal information (phishing). Thus, they are a valuable commodity to cyber criminals and, at the same time, a challenge for cybersecurity products to detect.

Take, for instance, ‘’: a website that supposedly grants scholarships to students in Oklahoma. However, things are not exactly as they appear to be. A closer inspection of the page’s source code reveals that it contains an outlink leading to ‘’: another website whose domain ownership was transferred in 2022 and got redirected to a different IP address to be later used to host pornography and gambling content!

That is how easily a once-safe domain can be compromised and put other websites containing outlinks to it in jeopardy. Outdated DNS security solutions and domain lookup tools often fail to make these subtle distinctions, as evident from the following pictures still classifying ‘’ under the Personal Blogs category.
