Next-Gen Malware Detection - Welcome to the Frontline of Cybersecurity with BitNinja!

Today, we’re exploring BitNinja’s cutting-edge malware detection technologies.  As cyber threats continue to evolve, staying ahead is not just an option—it's a necessity. We proudly offer two robust solutions: our reliable traditional server-based malware detection and our revolutionary AI-supported CloudScan. 

This article aims to provide you with a detailed understanding of how our malware detection systems operate, with a particular focus on our AI-driven CloudScan solution. Join us as we delve into these technologies, ensuring the security of your digital environments.

BitNinja’s Malware Detection: On-ServerScan vs. AI-based CloudScan

At BitNinja, we offer two distinct malware detection technologies to meet different needs and environments. The first is our traditional server-based (on-server) system, which processes everything locally on the server. While this ensures that files do not leave the server, the system's high demand for memory and CPU resources makes it less ideal for environments with limited resources, such as Virtual Private Servers (VPS). Additionally, our second solution is a completely revamped, cloud-based, AI-supported malware scanner. This system operates in the cloud, which significantly reduces the load on local resources. CloudScan enables faster scans and more effective identification of malicious software that the traditional system might miss.

Together, these systems allow us to provide comprehensive protection, leveraging the strengths of both local and cloud-based technologies to ensure maximum security for servers under various operating conditions. It's important to clarify that our clients have the flexibility to use either the AI scan, the on-server scan, or a combination of both, depending on their specific security needs and resource availability. For instance, the Active Scan feature, which monitors file changes, can remain on the server to avoid any delay in detecting malware in modified files. This hybrid approach allows for customizable and efficient malware detection, combining the thoroughness of on-server scanning with the speed and resource efficiency of our AI-driven CloudScan. Next, we will focus on the AI-based CloudScan, exploring its unique features and benefits in detail.

BitNinja’s CloudScan: AI-Powered Malware Detection Phases

We carry out our scanning process through multiple phases to ensure comprehensive malware detection and protection:

  • Quick Scan Phase: In this initial phase, we employ a processor and memory-efficient method to quickly generate a digital signature for each file. This signature is then uploaded to our signature database, which contains pre-scanned information on over two billion files. This extensive database allows us to quickly determine whether a file is harmful. If a file is identified as malicious, our BitNinja agent automatically decides whether to quarantine or clean the file. We first scan through all the files, and respond immediately to those that match known threats. This is the essence of the quick scan phase.
  • Deep Scan Phase: We upload files that do not match definitively in the quick scan phase to the cloud for deeper analysis. This phase involves classic analysis techniques typically used in on-server scanning, such as file signature analysis, behavior-based analysis, Yara rules, and structural signatures, in addition to structural analysis of injected malware. We also perform AI-based zero-day detection. Our AI model, developed using a supercomputer in collaboration with a Hungarian university, enables this advanced detection. We continuously retrain this model with new malware techniques, enhancing its ability to recognize and respond to previously unknown malicious codes more effectively than traditional methods.

These structured phases of scanning ensure that our system not only quickly reacts to known threats but also remains highly effective against new and evolving malware, maintaining robust security across all server environments.

BitNinja's Robust Security Arsenal and Defense Network: Powerful Defenses Against Today's Most Common Malware

One of the most common types of malware today is phoneix malware, which uses various techniques to re-infect an account immediately after its removal. These malware types employ several methods to achieve this, including persistence at the process level, making them difficult to detect using traditional malware scanners. To address this challenge, we introduced a new security module in the first quarter called Process Analyst, designed to monitor running processes. If it detects suspicious activity indicating that a process is part of a memory-persistent malware, it will neutralize it.

Another method used by malware for reinfection is writing itself into cron jobs, which means that when a cron runs, it reinjects itself into the system, or at least checks if it is already injected. Here, the malware scanner needs time to uncover the file and take necessary actions. During this time, a backdoor remains open. To combat this, BitNinja includes a specialized malware scanning sub-engine. The core configuration of BitNinja includes settings specifically designed to detect and eliminate such malware, continuously monitoring cron tab files and cleaning infections when necessary.

A third technique is peer-to-peer file persistence over the web, similar to torrent systems or other peer-to-peer file-sharing networks. Malware continuously infects multiple accounts and automatically detects and restores any missing files. This self-repair mehanism makes removal very challenging. For instance, if malware consists of 30 files and the system cleans the first 10 files, the malware can reinfect the already cleaned files before the system cleans the 11th file. This creates a relentless cat-and-mouse game. Moreover, if the malware scanner cannot effectively recognize general behavioural patterns, this type of malware can easily bypass detection, as it might look benign to the untrained eye.

BitNinja has a solution for this with Defense Network. This network is central to our proactive strategies servers protected by BitNinja worldwide share attack data in real time, enhancing our collective defense against new threats and zero-day attacks. When we remove malware, we automatically perform root cause analysis and blacklist the IP address responsible for the malware's presence, preventing reinfection. This approach ensures that we stay ahead of the malware and maintain a secure environment.
