EU Phishing Campaign

The threat actors utilized phishing emails with attached PDF documents or embedded HTML links. These emails targeted European companies and organizations, aiming to harvest account credentials and take over the victim’s Microsoft Azure cloud infrastructure.

Deceptive Phishing Campaigns

Goal: Identify susceptible individuals and gather information about ongoing phishing campaigns.

Approach: Launching controlled phishing campaigns with deceptive lures.

Conduct internal phishing campaigns with fake but believable phishing emails. Track who clicks on links, downloads attachments, or provides sensitive information. This reveals vulnerable individuals and gathers intelligence about attacker tactics.
