GIFTEDCROOK, a malware known for its ability to steal sensitive information from users' browsers and devices, has undergone significant updates in recent months. According to Arctic Wolf Labs, the threat actor behind the GIFTEDCROOK malware has evolved the malicious program into a potent intelligence-gathering tool, capable of exfiltrating a broad range of sensitive documents from compromised systems.
The threat landscape has seen numerous instances of sophisticated malware evolving over time, with GIFTEDCROOK being one such example. Initially documented by the Computer Emergency Response Team of Ukraine (CERT-UA) in early April 2025 in connection with a campaign targeting military entities, law enforcement agencies, and local self-government bodies, the malware has demonstrated an ability to adapt and improve its functionality.
The latest version of GIFTEDCROOK, versions 1.2 and 1.3, have introduced new features that enhance the malware's intelligence-gathering capabilities. The updated stealer can now harvest documents and files below 7 MB in size, specifically looking for files created or modified within the last 45 days. This includes popular file formats such as PDFs, spreadsheets, and even VPN configurations.
The email campaigns used by the threat actor to distribute GIFTEDCROOK have also undergone changes. The latest lures leverage military-themed PDF documents that contain macro-enabled Excel workbooks, which serve as a conduit to deploy the malware. Many users are unaware of the risks associated with macro-enabled Excel files and may unwittingly fall prey to phishing attacks.
GIFTEDCROOK's ability to gather sensitive information from compromised systems poses a significant risk to individuals working in public sector roles or handling sensitive internal reports. The malware's capacity to sift through recent files and exfiltrate documents like PDFs, spreadsheets, and even VPN configs points to a bigger goal: collecting intelligence.
The timing of the campaigns discussed in Arctic Wolf Labs' report demonstrates clear alignment with geopolitical events, particularly the recent negotiations between Ukraine and Russia in Istanbul. This suggests that the threat actor behind GIFTEDCROOK is actively involved in targeted cyber espionage.
"The progression from simple credential theft in GIFTEDCROOK version 1, to comprehensive document and data exfiltration in versions 1.2 and 1.3, reflects coordinated development efforts where malware capabilities followed geopolitical objectives to enhance data collection from compromised systems in Ukraine," Arctic Wolf said.
Arctic Wolf's analysis of the artifacts has revealed that the stealer started off as a demo in February 2025, before gaining new features with versions 1.2 and 1.3. These updates have enhanced GIFTEDCROOK's ability to exfiltrate sensitive information from compromised systems, making it an increasingly sophisticated intelligence-gathering tool.
The use of phishing emails containing macro-laced Microsoft Excel documents as a conduit to deploy GIFTEDCROOK is a common tactic employed by the threat actor. Many users don't realize how common macro-enabled Excel files are in phishing attacks and may slip past defenses because people often expect spreadsheets in work emails – especially ones that look official or government-related.
The captured information is bundled into a ZIP archive and exfiltrated to an attacker-controlled Telegram channel. If the total archive size exceeds 20 MB, it is broken down into multiple parts. By sending stolen ZIP archives in small chunks, GIFTEDCROOK avoids detection and skips around traditional network filters.
In the final stage, a batch script is executed to erase traces of the stealer from the compromised host. This ensures that the malware leaves no digital footprints behind, making it difficult for security professionals to detect.
The shift in functionality from a basic browser data stealer to a potent intelligence-gathering tool demonstrates the evolving nature of cyber threats. As threat actors continue to develop and refine their tactics, it is essential for organizations and individuals to stay vigilant and adapt their cybersecurity strategies accordingly.
Cybersecurity professionals should be aware of the new features introduced by GIFTEDCROOK and take necessary precautions to protect their systems from these types of threats. Implementing robust security measures, such as regular software updates, antivirus protection, and secure file sharing practices, can help minimize the risk of compromise.
In conclusion, the evolution of GIFTEDCROOK into a sophisticated intelligence-gathering tool poses significant risks to individuals and organizations worldwide. It is crucial for cybersecurity professionals and organizations to stay informed about emerging threats like this and take proactive measures to protect themselves from these types of attacks.
