We can load UIWIX.dll into a debugger—we'll use x32dbg. The attacker crafts the initial malicious file to appear legitimate. Once running on the system, malware can misuse Windows powershell.exe, wscript.exe, mshta.exe, wmic.exe. 9 Jul 2019 Microsoft has warned of a new fileless malware attack campaign that the WMIC tool with the '/Format' parameter, which allows the download and execution The JavaScript code in turn downloads payloads by abusing the 9 Jul 2019 The researchers spotted a sudden spike in Astaroth malware attacks. of the WMIC tool with the “/Format” parameter, which allows the download and The same applies to fileless malware: abusing fileless techniques does 20 Mar 2013 modules.

Hello! My name is Rohit Chettiar, and I am a Solutions Engineer at Rapid7. In this series, we will discuss why organizations should care about malicious PowerShell activity, how attackers use PowerShell to steal credentials (e.g., Mimikatz), and how to prevent and detect malicious PowerShell activity.. Why do attackers love PowerShell?
The release of Cobalt Strike 3.0 also saw the release of Advanced Threat Tactics, a nine-part course on red team operations and adversary simulations. This course is nearly six hours of material with an emphasis on process, concepts, and… Add to that the numerous types of CPU architectures, compilers, programming languages, application binary interfaces (ABIs), etc. and you’re left with an interesting, multifaceted, hard problem. Goals AND Executive Summary The goals of this paper are to explain why ransomware is still a serious threat to your organization – regardless of size – and what your organization can do to reduce exposure to, and damage from, ransomware… Abstract In an ever-changing landscape of adversary tactics, techniques and procedures (TTPs), malware remains the tool of choice for attackers to gain a foothold on target systems. Checks are performed by running queries or reading database configuration files. The goal of this tool is to highlight issues that need immediate attention and identify configuration settings that should be reviewed for appropriateness. Security leaders are no longer simply expected to design and implement a security strategy for their organization. As a key member of the business—and one that often sits in the C-suite—Cisos and security managers must demonstrate business…
8 Jul 2019 Because fileless attacks run the payload directly in memory or leverage legitimate system tools to run malicious code without having to drop executable files on the disk, The JavaScript code in turn downloads payloads by abusing the The use of the parameter /format causes WMIC to download the file
Currently, threat actors prefer archived files or weaponized Microsoft Office productivity documents to deliver this malicious software to the endpoint. Popular scripting languages (JavaScript, batch files, PowerShell, Visual Basic scripts, etc.) are used. The tests involve both staged and non-staged malware samples, and deploy obfuscation and/or encryption of malicious code before execution… Security IBM Security Solutions WG Research Report - Free download as PDF File (.pdf), Text File (.txt) or read online for free.

A new feature of the FireEye Endpoint Security platform detected a Cerber ransomware campaign and alerted customers in the field. The campaign distributed a malicious Microsoft Word document that could contact an attacker-congrolled website… The malicious payload existed entirely in memory, with no files written on disk, thus gaining the title of the very first modern fileless malware. Code Red demonstrated that in-memory approaches were not only possible but also practical… Semmle security researcher Man Yue Mo has disclosed a critical remote code execution vulnerability in the popular Apache Struts web application framework that could allow remote attackers to run malicious code on the affected servers.
In our analysis, we found that a total of fifteen organizations had their credentials stolen in some fashion and stored in text files for the OilRig group to then abuse for additional attacks.

Attackers Abuse WMIC to Download Malicious Files Posted on August 30, 2018 September 3, 2018 Author Cyber Security Review Malware authors use WMIC and a host of other legitimate tools to deliver information-stealing malware, highlighting the continued use of living off the land tactics. Attackers Abuse WMIC to Download Malicious Files Posted on August 30, 2018 September 3, 2018 Malware authors use WMIC and a host of other legitimate tools to deliver information-stealing malware, highlighting the continued use of living off the land tactics. Step 2: WMIC abuse, part 1. The BAT command runs the system tool WMIC.exe: The use of the parameter /format causes WMIC to download the file v.txt, which is an XSL file hosted on a legitimate-looking domain. The XSL file hosts an obfuscated JavaScript that is automatically run by WMIC. We recently found a malware that abuses two legitimate Windows files — the command line utility wmic.exe and certutil.exe, a program that manages certificates for Windows — to download its payload onto the victim’s device. What’s notable about these files is that they are also used to download other files as part of its normal set of features, making them susceptible to abuse for These can come from malicious macro codes in the form of JavaScript or VisualBasic (VBA) scripts embedded within Office documents, PDFs, archives, or seemingly benign files. Once opened, these macros will run the scripts and often abuse legitimate tools like PowerShell to launch, download, and execute more code, scripts, or payloads. Fileless attacks have traditionally abused Windows OS tools or processes, but in December 2019, a fileless was detected. They contain malicious code hiding in memory of legitimate applications. And unlike file-based malware that is dropped to disk and run from the hard drive, fileless attacks are executed right from system memory. Researchers from Symantec observed malware authors abusing WMIC to download the information-stealing malware. How the attack works. Attackers use to deliver a shortcut file (.lnk) through URL or link in email or as an attachment, once the user opens the file contains a WMIC command, it downloads the malicious file from the attacker’s remote
