Automated Analysis

When analyzing a suspicious link you may think going to a site like urlscan.io would be the best approach. This works in some cases, however, be aware that some bad guys will actively evade calls from these types of sites (URL analysis sites). They will do this based on user-agent or the source IP address making the call.


In our case if you try to look up the malicious URL at urlscan.io you will see the site doesn’t even load:


Virustotal shows nothing malicious

Manual Analysis

A standard curl to the site will 302 redirect you to a chase login stealer:

A curl with a user agent for an Iphone with IOS 11 will return a javascript that will also direct you to the password stealer:

curl -A "Mozilla/5.0 (iPhone; CPU iPhone OS 11_0 like Mac OS X) AppleWebKit/604.1.38 (KHTML, like Gecko) Version/11.0 Mobile/15A356 Safari/604.1" https://zrruqhmedbbghufdta.page.link/Go1D?17735551234
