What does the BNVL label mean?

BitNinja Server Security’s BNVL identifiers are intended for use to identify publicly known information security vulnerabilities in publicly released software packages. This project was designed to collect and analyze attack information from the BitNinja network after cluster analysis by the AI-powered Attack Vector Miner. More than 100 vulnerability types have been discovered with this project so far, so we decided to publish this platform to help to keep Linux server owners up-to-date.

Important! All listed BNVL vulnerabilities are protected by BitNinja PRO, so please check your configurations if your infrastructure is affected by any of them.

Syntax for BNVL labels:

BNVL prefix + Year + Arbitrary Digits

According to the SANS Institute Security Risks Report for 2007, brute-force/dictionary attacks against remote services such as SSH, are one of the Top-20 most common forms of attack on the Internet that compromise servers. In particular, Unix-based and Mac OS X servers that run an SSH service to allow administrators secure remote connections are at risk. The ISO has seen an increased number of systems compromised via brute-Force/dictionary attack. The attacks are continuous and facilitated through the process of improving dictionaries when lax countermeasures are in place. An excessive number of failed log-ins is a sign of brute-force/dictionary attack against your SSH server.
