Acknowledging the severity of the situation, PTA has also called for heightened user awareness concerning phishing risks, advising caution when clicking on URLs, especially those received via email. Additionally, the recommendation to implement multi-factor authentication aims to further enhance account security.

As part of its ongoing efforts to ensure cybersecurity, PTA encourages organizations and individuals to monitor for unusual activities related to email access, credentials, and authentication tokens. This comprehensive approach seeks to establish a resilient and secure digital environment for all citizens.
