Researchers at Kaspersky have identified a new variant of the Eagerbee malware framework being deployed against government organizations and ISPs in the Middle East, offering extensive capabilities to attackers. The threat poses significant concerns for organizations in this region and underscores the need for continued vigilance against persistent malware.
Eagerbee, a sophisticated backdoor, has been identified by Kaspersky researchers as being deployed against government organizations and ISPs in the Middle East. The Eagerbee malware framework is linked to a threat group called "CoughingDown" through code similarities and IP address overlaps. The attack vector of Eagerbee remains unknown, but previous cases suggest it may be exploited using the Microsoft Exchange ProxyLogon flaw (CVE-2021-26855). Five plugins are part of the Eagerbee framework: File Manager Plugin, Process Manager Plugin, Remote Access Manager Plugin, Service Manager Plugin, and Network Manager Plugin. The deployment of Eagerbee poses a significant concern due to potential disruptions and data theft, particularly in the Middle East.
In a recent development that has sent shockwaves throughout the cybersecurity community, researchers at Kaspersky have identified a new variant of the Eagerbee malware framework being deployed against government organizations and internet service providers (ISPs) in the Middle East. This latest iteration of the malware, known as Eagerbee, is a sophisticated backdoor that offers extensive capabilities to attackers, including remote access, file management, process manipulation, and network monitoring.
The Eagerbee malware framework has been linked to a threat group dubbed "CoughingDown" by Kaspersky researchers. The connection between the two was established based on code similarities and IP address overlaps. While the exact nature of the relationship between Eagerbee and CoughingDown is still unclear, it appears that the former may be a tool used by the latter to gain access to compromised systems.
Eagerbee's attack vector remains unknown, but previous cases have shown that attackers have breached East Asian organizations by exploiting the Microsoft Exchange ProxyLogon flaw (CVE-2021-26855). The malware drops an injector called "tsvipsrv.dll" in the system32 directory, which then loads the payload file "ntusers0.dat." Once the system starts up, Windows executes the injector, which abuses several services to write the backdoor payload in memory using DLL hijacking.
The Eagerbee backdoor is configured to run 24/7 and appears on infected systems as "dllloader1x64.dll." Upon initialization, it establishes a TCP/SSL channel with a command-and-control (C2) server from where it can receive additional plugins that extend its functionality. The plugins are injected into memory by a plugin orchestrator called "ssss.dll," which manages their execution.
Researchers at Kaspersky have documented five plugins that are part of the Eagerbee framework: File Manager Plugin, Process Manager Plugin, Remote Access Manager Plugin, Service Manager Plugin, and Network Manager Plugin. Each of these plugins offers distinct capabilities to attackers:
* The File Manager Plugin handles file system operations, including listing, renaming, moving, copying, and deleting files or directories. It can adjust file permissions, inject additional payloads into memory, and execute command lines.
* The Process Manager Plugin manages system processes by listing running processes, launching new ones, and terminating existing ones. It can execute command lines or modules in the security context of specific user accounts.
* The Remote Access Manager Plugin facilitates remote access by enabling RDP sessions, maintaining concurrent RDP connections, and providing command shell access. It also downloads files from specified URLs and injects command shells into legitimate processes for stealth.
* The Service Manager Plugin controls system services by creating, starting, stopping, deleting, or enumerating them. It can manage both standalone and shared service processes while collecting service status details.
* The Network Manager Plugin monitors and lists active network connections, gathering details like state, local/remote addresses and ports, and associated process IDs for both IPv4 and IPv6 protocols.
The deployment of Eagerbee against Middle Eastern governments and ISPs is a significant concern due to the potential for widespread disruption and data theft. Organizations in this region are advised to patch their Microsoft Exchange servers with the ProxyLogon vulnerability fixed and use the indicators of compromise listed by Kaspersky's report to catch the threat early.
The global nature of the attacks suggests that Eagerbee has been used elsewhere, as reported cases have also emerged in Japan. This development serves as a stark reminder of the evolving nature of cybersecurity threats and the importance of staying vigilant against persistent malware like Eagerbee.
