Microsoft dismantles Russian cyber actor Star Blizzard’s network

Microsoft’s Digital Crimes Unit (DCU) has effectively dismantled a network operated by the notorious Russian-state cyber actor, ‘Star Blizzard’. This operation, conducted in collaboration with the United States Department of Justice, has significantly impacted the group’s capacity to execute cyberattacks, which have escalated in both frequency and sophistication since the start of 2023.

The campaign by Star Blizzard targeted over 30 organizations, including non-governmental organisations, journalists, and think tanks. These attacks were orchestrated predominantly through spear phishing campaigns designed to steal sensitive data and thwart efforts related to democratic processes. Spear phishing involves tailored email schemes crafted to trick individuals into divulging confidential information. The group’s proficiency in crafting these emails has improved, making detection increasingly challenging.

In a critical move, the DCU has seized 66 domains that Star Blizzard utilised to carry out their operations globally. The civil action, now unsealed, reveals a concerted effort to dismantle the infrastructure the Russian group relied upon. This disruption is particularly timely with the forthcoming 2024 US Presidential election, as Microsoft expressed awareness of the potential interference Russian state actors may exert to undermine Western democracies.

Active since 2017, Star Blizzard has especially targeted military officials in the United Kingdom and the United States, focusing on those involved in providing support to Ukraine and its allies. This strategic targeting underlines the geopolitical motivations behind the cyber attacks.

The operation against Star Blizzard forms part of a broader series of measures to combat cyber threats that have seen Microsoft and its partners seizing over 100 websites from Russian state-backed criminals. Such efforts highlight the ongoing nature of cyber warfare, described as a “shadow war”, which has intensified following the Russian invasion of Ukraine. Efforts to attack critical infrastructure, deploy ransomware, and conduct misinformation campaigns have increased, with multiple Russian cybercriminals facing sanctions from the UK government.

The report underscores a rise in phishing emails mimicking messages from Microsoft services. Check Point, a cybersecurity firm, noted a significant surge in such emails, with over 5,000 detected in September alone. These fraudulent emails mimic the style, tone, and appearance of legitimate Microsoft correspondences, often incorporating privacy policy statements or links to authentic Microsoft resources.

In light of these sophisticated threats, Check Point stresses the importance of comprehensive user-awareness training to equip employees with the skills to recognise phishing scams beyond traditional spelling or stylistic errors. Additionally, organisations are encouraged to adopt AI-powered email security solutions and ensure their infrastructure is regularly updated to fend off such threats.

These developments underscore the continuous challenge of protecting digital spaces from well-equipped and coordinated cyber adversaries.
