Intelligence Report: Russian hackers attack Western military mission using malicious drive – BleepingComputer

1. BLUF (Bottom Line Up Front)

The Russian hacking group Gamaredon has launched a cyberattack on a Western military mission in Ukraine, utilizing removable drives to deploy the GammaSteel malware. The campaign, active from February to March 2025, demonstrates an evolution in Gamaredon’s tactics, including the use of PowerShell-based tools and legitimate services for evasion. The attack poses significant risks to Western networks, highlighting the need for enhanced cybersecurity measures.

2. Detailed Analysis

The following structured analytic techniques have been applied for this analysis:

General Analysis

The attack by Gamaredon involved the use of malicious .LNK files on removable drives to gain initial access to targeted systems. This method aligns with their historical tactics but shows a shift towards more sophisticated techniques, such as increased obfuscation and the use of PowerShell scripts. The malware, GammaSteel, is capable of stealing sensitive documents and exfiltrating data using PowerShell web requests or cURL over Tor if necessary. The campaign’s focus on espionage underscores Gamaredon’s persistent threat to Western interests.

3. Implications and Strategic Risks

The attack on a Western military mission in Ukraine indicates a broader strategic risk to national security and regional stability. The evolution of Gamaredon’s tactics suggests a potential increase in the frequency and sophistication of future attacks. This poses a threat not only to military operations but also to economic interests, as the theft of sensitive information could lead to significant geopolitical and financial repercussions.

4. Recommendations and Outlook

Recommendations:

• Enhance cybersecurity protocols by implementing advanced threat detection systems and regular security audits.
• Increase awareness and training for personnel on the risks associated with removable drives and phishing attempts.
• Consider regulatory measures to enforce stricter controls on data access and transfer within sensitive environments.

Outlook:

Best-case scenario: The implementation of robust cybersecurity measures mitigates the risk of future attacks, maintaining the integrity of Western military operations.
Worst-case scenario: Continued evolution of Gamaredon’s tactics leads to successful breaches, resulting in significant data loss and geopolitical instability.
Most likely scenario: Incremental improvements in cybersecurity reduce the frequency of successful attacks, but persistent threats remain a challenge.
