CISA, in collaboration with international counterparts including the UK-NCSC, ASD’s ACSC, CCCS, NCSC-NZ, NSA, FBI, and Cyber Command CNMF, has released a joint Cybersecurity Advisory on the Russia-based threat actor group known as Star Blizzard. This advisory aims to provide insights into the specific tactics, techniques, and delivery methods employed by Star Blizzard in its ongoing worldwide spear-phishing campaigns. Notable techniques utilized by Star Blizzard include impersonating known email contacts, creating fraudulent social media profiles, employing webmail addresses from providers like Outlook and Gmail, and establishing malicious domains that mimic legitimate organizations.
The advisory highlights the need for network defenders and critical infrastructure organizations to scrutinize the detailed information provided in the release and enhance their cybersecurity posture accordingly to guard against potential exploits by Star Blizzard. Additionally, CISA urges software developers to integrate secure-by-design and -default principles into their software development practices.
This approach is crucial for limiting the impact of threat actor activities and bolstering overall cybersecurity resilience. In light of the increasing sophistication of cyber threats, the advisory underscores the importance of adopting proactive measures, raising awareness, and fostering collaborative efforts on a global scale to counter the evolving tactics employed by threat actors like Star Blizzard. The guidance also directs stakeholders to CISA’s Cross-Sector Cybersecurity Performance Goals for comprehensive insights into safeguarding against prevalent and impactful threats and encourages reference to CISA’s Secure by Design webpage for additional information on secure software development practices.
