Demystifying the Role of Rule-Based Detection in AI Systems for Windows Malware Detection

Malware detection increasingly relies on AI systems that integrate signature-based detection with machine learning. However, these components are typically developed and combined in isolation, missing opportunities to reduce data complexity and strengthen defenses against adversarial EXEmples,...

Dynmx - Signature-based Detection Of Malware Features Based On Windows API Call Sequences

dynmx spoken dynamics is a signature-based detection approach for behavioural malware features based on Windows API call sequences. In a simplified way, you can think of dynmx as a sort of YARA for API call traces so called function logs originating from malware sandboxes. Hence, the data basis f...

The Battle Against Business Logic Attacks: Why Traditional Security Tools Fall Short

As the digital landscape continues to evolve, so do the tactics utilized by bad actors that are seeking to exploit application vulnerabilities. Among the most insidious types of attacks are business logic attacks BLAs. Unlike known attacks, which can be identified by signatures or patterns, such ...

Real-Time Defense of Multi-Cloud Environments From Malicious Attacks and Threats

Organizations today cannot detect real-time threats at runtime due to the multi-cloud infrastructure, resulting in the possibility of malicious actors exploiting the environment. It is imperative for the modern organization to have a solution to detect advanced run-time threats in real-time to...

DEF CON 2019: MacOS Gets a Malware Beatdown in Attack Demo

LAS VEGAS – On Friday, Mac security researcher Patrick Wardle showed how an attacker can repurpose someone else’s Mac malware, create false attribution flags and sidestep Mac anti-malware defenses with ease. The attack scenarios were his own and meant to serve as cautionary examples and reasons w...

Why Malwarebytes decided to participate in AV testing

Starting this month, Malwarebytes began participating in the antivirus software for Windows comparison test performed by AV-test.org. This is uncharted territory for us, as we have refrained from participating in these types of tests since our inception. Although recent testing results show...

Traditional AV solutions shown ineffective in real-time global heat map

It's no secret that antivirus technology AV has faced increased scrutiny in the tech industry for quite some time. With signature-based detection methods, traditional AV solutions are simply weak against unknown malware and other malicious content. Meanwhile, consumers and businesses continue to...

Fileless Malware: A Hidden Threat

Malware is advancing at an unprecedented rate, with four new strains discovered every minute, Slate reported. This is already a lot for businesses to worry about and it doesn't even cover the other threats that haven't been detected. Many attackers have evolved their techniques to evade common...

Obfuscation in the Wild: Targeted Attackers Lead the Way in Evasion Techniques

Throughout 2017 we have observed a marked increase in the use of command line evasion and obfuscation by a range of targeted attackers. Cyber espionage groups and financial threat actors continue to adopt the latest cutting-edge application whitelisting bypass techniques and introduce innovative...
