Security researchers at threat intelligence firms BlackBerry and Intezer identified a stealthy Linux malware dubbed Symbiote that steals users' credentials and provide backdoor access to infected devices for its operators. As per reports, the malware, which was developed in November 2021, is being employed in the attacks against financial sector in Latin America, including banks like Banco do Brasil and Caixa. The malware primary goal is to intercept account credentials and facilitate backdoor access to compromised systems to its operators. Additionally, It infects running process using a Linux feature called 'LD_PRELOAD' and uses BPF (Berkeley Packet Filter) to hide malicious network traffic. While investigating the stealthy malware, researchers also found that, when system admins attempt to use any packet capture tool on the compromised system, it injects BPF bytecode into the system kernel and filter out results that would uncover its activity. After Symbiote hijacks all running processes, it provides a rootkit and backdoor functionality for the threat actor to execute privileged commands and to hide its existence. Previously, researchers also revealed about another Linux-based malware called BPFDoor that loaded a Berkeley Packet Filter (BPF) sniffer to monitor network traffic and start a bind shell while bypassing firewall protections.
