Symbiote Backdoor in Linux

Interesting: What makes Symbiote different from other Linux malware that we usually come across, is that it needs to infect other running processes to inflict damage on infected machines. Instead of being a standalone executable file that is run to infect a machine, it is a shared object SO libra...

Stealthy Symbiote Linux malware is after financial institutions

Symbiote, a new "nearly impossible to detect" Linux malware, targeted financial sectors in Latin America—and the threat actors behind it might have links to Brazil. These findings were revealed in a recent report, a joint effort between the Blackberry Research Team and Dr. Joakim Kennedy, a...

Linux Malware Deemed ‘Nearly Impossible’ to Detect

A new Linux malware that’s “nearly impossible to detect” can harvest credentials and gives attackers remote access and rootkit functionality by acting in a parasitic way to infect targets, researchers said. Researchers from The BlackBerry Research and Intelligence Team have been tracking the...

CVE-2020-28045

An unsigned-library issue was discovered in ProlinOS through 2.4.161.8859R. This OS requires installed applications and all system binaries to be signed either by the manufacturer or by the Point Of Sale application developer and distributor. The signature is a 2048-byte RSA signature verified in...

CVE-2020-28045

CVE-2020-28045 affects ProlinOS up to 2.4.161.8859R. Root cause: shared libraries are not required to be signed and are not verified, allowing an attacker with local access to load a crafted shared object via LD_PRELOAD, bypassing kernel ELF verification and executing unsigned code. This creates ...

PathAuditor - Detecting Unsafe Path Access Patterns

The PathAuditor is a tool meant to find file access related vulnerabilities by auditing libc functions. The idea is roughly as follows: Audit every call to filesystem related libc functions performed by the binary. Check if the path used in the syscall is user-writable. In this case an unprivileg...
