Phishing campaigns leverage Google Firebase storage

New phishing campaigns tracked by Trustware deploy schemes that harvest credentials by taking advantage of “the reputation and services” of the Google Cloud’s Firebase mobile and web application development platform.

The bogus emails cut across industries and tap Firebase’s data storage API in a Google Cloud Storage bucket, while hiding malicious URLs in phishing emails that lead to fake pages.

“While these campaigns used common phishing lures, what made them unique was the adoption of Google Firebase storage URLs embedded in the phishing messages,” Trustware researcher Fahim Abbasi wrote in a blog post.  “In effect, actors leverage the repute and services of Google Cloud’s infrastructure to host their phishing credential harvesting pages.”
