Ukraine’s Computer Emergency Response Team (CERT-UA) has alerted about phishing campaigns by the UAC-0099 group, targeting defense sectors with malware to compromise systems and steal sensitive military data. These attacks, linked to ongoing cyber warfare amid conflicts, have increased by 70% in 2024, particularly from Russian sources. Ukraine emphasizes the importance of email filtering, user awareness, and monitoring networks to counter these threats. The advisory encourages organizations to patch vulnerabilities as international partners step in to bolster response efforts. This highlights the critical need for robust cybersecurity measures within defense sectors globally, including India, where similar threats could emerge amidst rising geopolitical tensions.
