🔧Technical Breakdown
The attack employed a multi-faceted approach to bypass traditional email security filters:
- **Phishing Campaigns:** Attackers initiated phishing emails that contained links to malicious QR codes and password-protected attachments.
- **Social Engineering:** These emails were crafted to appear legitimate, often mimicking communication from trusted vendors or internal departments.
- **Multi-Stage Verification:** Upon clicking the links, victims were led through a series of verification steps, often involving fake login pages that harvested credentials.
- **Cloud-Based Techniques:** The attackers leveraged trusted cloud services for hosting malicious content, enabling them to evade detection by conventional security systems.

🔍Root Causes
The following vulnerabilities contributed to the success of the phishing attacks:
- **Inadequate Email Filtering:** Many organizations relied on outdated or insufficient email filtering systems that failed to detect sophisticated phishing attempts.
- **Lack of User Training:** Employees were not adequately trained to recognize phishing attempts or the importance of verifying suspicious communications.
- **Use of Cloud Services:** Organizations did not implement strict controls over the use of cloud services, making it easier for attackers to host malicious content.
- **Weak Account Security:** Many users had weak passwords and did not utilize multi-factor authentication, making it easier for attackers to gain unauthorized access.
