A Sophisticated Cyber Attack Campaign Targets Windows Systems: Steal-It

A Sophisticated Cyber Attack Campaign Targets Windows Systems

A new sophisticated cyber attack has been detected that is targeting Windows systems using a unique method. This campaign, dubbed Steal-It by Zscaler ThreatLabz, utilizes the PowerShell script tied to a legitimate red teaming tool to steal NTLMv2 hashes. The primarily affected locations are Australia, Poland, and Belgium.

Steal-It: A New Cyber Threat

The Steal-It campaign showcases the lengths threat actors will go to compromise a system. By utilizing legitimate tools, they can avoid detection and cover their tracks.

In this operation, attackers steal and exfiltrate NTLMv2 hashes using customized versions of Nishang’s PowerShell script. PowerShell is a powerful scripting language typically used by system administrators for task automation and configuration management.

This campaign highlights the importance of advanced cyber incident response and robust security measures to protect against sophisticated threats.

Targeted Systems and Locations

The primary targets of this campaign are Windows systems. Given the prevalence of Windows operating systems in businesses and personal computers, this allows the attackers to cast a wide net.

Australia, Poland, and Belgium have been highlighted as the main locations affected by this campaign. However, the global nature of cyber threats means that systems anywhere can be targeted.

As a result, individuals, small-medium organisations, and large organisations everywhere need to be aware of this threat and take appropriate measures to protect their systems.

The Role of Nishang in this Campaign

Nishang, a legitimate red teaming tool often used for penetration testing, is being manipulated by the attackers in this campaign. Rather than being used for its intended defensive purposes, it’s being used maliciously.

Customized versions of Nishang’s PowerShell script are used to steal and exfiltrate NTLMv2 hashes. This method of attack demonstrates the adaptability and resourcefulness of threat actors.

These activity underscores the importance of monitoring and controlling the use of legitimate tools within an organization, as part of a comprehensive ISO 27001 audit.

Defending Against the Steal-It Campaign

Defending against this type of attack requires a multi-faceted approach. First and foremost, organizations must have robust cybersecurity measures in place, including SIEM and use case assessments.

Organizations must also educate their staff about the risks of cyber threats. This includes ensuring they understand what phishing looks like and that they should be cyber aware.

Finally, it is crucial to have an effective incident response plan in place. Rapid response is key in minimizing the impact of a cyber attack.
