What it detects

This rule detects web requests to the /login/email and /login/identifier endpoints combined with the Poll.js resource which are DOM and URL fingerprints of the 0ktapus phishing kit that impersonates Okta and single sign-on portals. This is important because these paths are hardcoded artifacts of the kit used to harvest credentials and multi-factor codes so their presence in proxy logs indicates a user interacting with a 0ktapus phishing site.
