AlienVault OTX Vulnerabilities

AlienVault OTX Malware

A new campaign targeting Indian government entities was uncovered, utilizing three backdoors: SHEETCREEP, FIREPOWER, and MAILCREEP. These tools leverage legitimate cloud services like Google Sheets, Firebase, and Microsoft Graph API for command and control, enabling the attackers to blend in with normal traffic. The campaign, named Sheet Attack, employed PDFs and malicious LNK files as initial infection vectors. Evidence suggests the use of generative AI in malware development. While sharing similarities with APT36, the campaign's unique characteristics point to either a new Pakistan-linked group or an APT36 subgroup. The attackers demonstrated hands-on-keyboard activity and deployed additional payloads, including a document stealer, to selected targets.

The Sheet Attack campaign is a targeted Advanced Persistent Threat (APT) operation focusing on Indian government entities. It employs three distinct backdoors—SHEETCREEP, FIREPOWER, and MAILCREEP—that utilize legitimate cloud platforms such as Google Sheets, Firebase, and Microsoft Graph API to establish command and control (C2) channels. This approach enables the attackers to evade traditional network security monitoring by blending malicious traffic with legitimate cloud service communications. Initial infection vectors include weaponized PDFs and malicious Windows LNK shortcut files, which are common vectors for social engineering and spear-phishing attacks. The campaign shows evidence of leveraging generative AI techniques to develop or enhance malware capabilities, indicating a sophisticated and evolving threat actor. Although the campaign shares similarities with the Pakistan-linked APT36 group, unique operational characteristics suggest either a new threat actor or a subgroup. The attackers demonstrate hands-on-keyboard activity, indicating manual control and tailored payload deployment, including document stealers, to exfiltrate sensitive information from targeted systems. The campaign's stealthy use of cloud services for C2, combined with targeted payloads and social engineering, makes detection and response challenging. No public exploits or patches are currently available, and the campaign is assessed as medium severity due to its targeted nature and complexity.
