Before hunting malware, every researcher needs to find a system where to analyze it. There are several ways to do it: build your own environment or use third-party solutions. Today we will walk through all the steps of creating a custom malware sandbox where you can perform a proper analysis without infecting your computer. And then compare it with a ready-made service. Why do you need a malware sandbox?  A sandbox allows detecting cyber threats and analyzing them safely. All information remains secure, and a suspicious file can't access the system. You can monitor malware processes, identify their patterns and investigate behavior. Before setting up a sandbox, you should have a clear goal of what you want to achieve through the lab.  There are two ways how to organize your working space for analysis: Custom sandbox.  Made from scratch by an analyst on their own, specifically for their needs. A turnkey solution.  A versatile service with a range of configurat...

However, manual lab setup and configuration can prove to be a laborious and time-consuming process. In this article, we'll look at 4 ways to create a reverse engineering lab, discuss how to save time, and, potentially, improve the detection rate using a  sandbox-as-a-service , and a recommended list of tools for a comprehensive setup. What is a malware analysis lab? In essence, a malware analysis lab provides a safe, isolated space for examining malware. The setup can range from a straightforward virtual machine using VirtualBox to a more intricate network of interconnected machines and actual networking hardware. But in this article, we'll look at building a lab tailored for static analysis, so what we will need is a secure environment where we can run disassemblers, edit binary files and debug. There are a couple of ways we can go about creating it: 1 — Virtualization Perhaps the simplest way to create a secure and isolated environment is by using a virtual machine....

Attack surfaces are growing faster than security teams can keep up – to stay ahead, you need to know what's exposed and where attackers are most likely to strike. With cloud adoption dramatically increasing the ease of exposing new systems and services to the internet, prioritizing threats and managing your attack surface from an attacker's perspective has never been more important. In this guide, we look at why attack surfaces are growing and how to monitor and manage them properly with  tools like Intruder . Let's dive in. What is your attack surface? First, it's important to understand what we mean when we talk about an attack surface. An attack surface is the sum of your digital assets that are 'reachable' by an attacker – whether they are secure or vulnerable, known or unknown, in active use or not. You can also have both internal and external attack surfaces - imagine for example a malicious email attachment landing in a colleague's inbox, vs a new FTP server being...

UTM (Unified threat management) is thought to be an all-in-one solution for cybersecurity. In general, it is a versatile software or hardware firewall solution integrated with IPS (Intrusion Prevention System) and other security services. A universal gateway allows the user to manage network security with one comprehensive solution, which makes the task much easier. In addition, compared to a conventional firewall, such systems are capable of detecting and blocking more sophisticated attacks. SafeDNS has recently released such a solution, and this is what this article is going to be about. Who needs UTMs? Most of all, UTMs are valued by SMEs - the all-in-one solution makes it simple to manage all their cybersecurity solutions and services. This also cuts down a lot of communications between vendors, since UTMs are easily supported by one IT team. This leads to another upside of the system - it can be cost-effective, as there is no need to pay a bunch of vendors & extra for tech ...

A new ransomware-as-service (RaaS) operation called MichaelKors has become the latest file-encrypting malware to target Linux and  VMware ESXi systems  as of April 2023. The development points to cybercriminal actors increasingly setting their eyes on the ESXi, cybersecurity firm CrowdStrike said in a report shared with The Hacker News. "This trend is especially noteworthy given the fact that ESXi, by design, does not support third-party agents or AV software," the company said. "In fact, VMware goes as far as to claim it's not required. This, combined with the popularity of ESXi as a widespread and popular virtualization and management system, makes the hypervisor a highly attractive target for modern adversaries." The  targeting of VMware ESXi hypervisors  with ransomware to scale such campaigns is a technique known as  hypervisor jackpotting . Over the years, the approach has been adopted by several ransomware groups, including Royal. What's more...

In 2024, ransomware attacks targeting VMware ESXi servers reached alarming levels, with the average ransom demand skyrocketing to $5 million. With approximately 8,000 ESXi hosts exposed directly to the internet (according to Shodan), the operational and business impact of these attacks is profound. Most of the Ransomware strands that are attacking ESXi servers nowadays, are variants of the infamous Babuk ransomware, adapted to avoid detection of security tools. Moreover, accessibility is becoming more widespread, as attackers monetize their entry points by selling Initial Access to other threat actors, including ransomware groups. As organizations are dealing with compounded threats on an ever-expanding front: new vulnerabilities, new entry points, monetized cyber-crime networks, and more, there is ever-growing urgency for enhanced security measures and vigilance. The architecture of ESXi Understanding how an attacker can gain control of the ESXi host begins with understanding the ...
