Cybersecurity researchers have warned about a Windows version of a wiper malware that was previously observed targeting Linux systems in cyber attacks aimed at Israel. Dubbed  BiBi-Windows Wiper  by BlackBerry, the wiper is the Windows counterpart of  BiBi-Linux Wiper , which has been put to use by a pro-Hamas hacktivist group in the wake of the Israel-Hamas war last month. "The Windows variant [...] confirms that the threat actors who created the wiper are continuing to build out the malware, and indicates an expansion of the attack to target end user machines and application servers," the Canadian company  said  Friday. Slovak cybersecurity firm ESET is  tracking  the actor behind the wiper under the name BiBiGun, noting that the Windows variant (bibi.exe) is designed to overwrite data in the C:\Users directory recursively with junk data and append ".BiBi" to the filename. The BiBi-Windows Wiper artifact is said to have been compiled on October 21, 2023, two

XWorm is a relatively new representative of the remote access trojan cohort that has already earned its spot among the most persistent threats across the globe.  Since 2022, when it was first observed by researchers, it has undergone a number of major updates that have significantly enhanced its functionality and solidified its staying power.  The analyst team at  ANY.RUN  came across the newest version of the malware and could not refuse the opportunity of taking it apart to examine XWorm mechanics configurations. Here is how they did it and what they found.  The XWorm sample's source  The sample in question was discovered in ANY. RUN's database of malware, a repository containing detailed analysis reports on all files and links that have been uploaded by users of the sandbox in public mode.  A quick look at the results of the analysis revealed that the sample was initially distributed via MediaFire, a file-hosting service. The malware was packaged in a RAR archive and p

For years, securing a company's systems was synonymous with securing its "perimeter." There was what was safe "inside" and the unsafe outside world. We built sturdy firewalls and deployed sophisticated detection systems, confident that keeping the barbarians outside the walls kept our data and systems safe. The problem is that we no longer operate within the confines of physical on-prem installations and controlled networks. Data and applications now reside in distributed cloud environments and data centers, accessed by users and devices connecting from anywhere on the planet. The walls have crumbled, and the perimeter has dissolved, opening the door to a new battlefield: identity . Identity is at the center of what the industry has praised as the new gold standard of enterprise security: "zero trust." In this paradigm, explicit trust becomes mandatory for any interactions between systems, and no implicit trust shall subsist. Every access request, regardless of its origin,

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.

Unknown malware presents a significant cybersecurity threat and can cause serious damage to organizations and individuals alike. When left undetected, malicious code can gain access to confidential information, corrupt data, and allow attackers to gain control of systems. Find out how to avoid these circumstances and detect unknown malicious behavior efficiently.  Challenges of new threats' detection While known malware families are more predictable and can be detected more easily, unknown threats can take on a variety of forms, causing a bunch of challenges for their detection: Malware developers use polymorphism, which enables them to modify the malicious code to generate unique variants of the same malware.  There is malware that is still not identified and doesn't have any rulesets for detection. Some threats can be Fully UnDetectable (FUD) for some time and challenge perimeter security.  The code is often encrypted, making it difficult to detect by signature-based

Based on the findings of Malwarebytes' Threat Review for 2022, 40 million Windows business computers' threats were detected in 2021. In order to combat and avoid these kinds of attacks, malware analysis is essential. In this article, we will break down the goal of malicious programs' investigation and how to do malware analysis with a sandbox. What is malware analysis?  Malware analysis is a process of studying a malicious sample. During the study, a researcher's goal is to understand a malicious program's type, functions, code, and potential dangers. Receive the information organization needs to respond to the intrusion. Results of analysis that you get: how malware works: if you investigate the code of the program and its algorithm, you will be able to stop it from infecting the whole system. characteristics of the program: improve detection by using data on malware like its family, type, version, etc. what is the goal of malware: trigger the sample's

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 configurations to meet yo
