Oct 16, 2024 Threat Intelligence / Malware Analysis
To defend your organization against cyber threats, you need a clear picture of the current threat landscape. This means constantly expanding your knowledge about new and ongoing threats. There are many techniques analysts can use to collect crucial cyber threat intelligence. Let's consider five that can greatly improve your threat investigations. Pivoting on С2 IP addresses to pinpoint malware IP addresses used by malware to communicate with its command and control (C2) servers are valuable indicators. They can help not only update your defenses, but also identify related infrastructure and tools belonging to threat actors.  This is done using the pivoting method, which lets analysts find additional context on the threat at hand with an existing indicator. To perform pivoting, analysts use various sources, including threat intelligence databases that store large volumes of fresh threat data and offer search capabilities. One useful tool is Threat Intelligence Lookup from AN...
5 Must-Have Tools for Effective Dynamic Malware Analysis

5 Must-Have Tools for Effective Dynamic Malware Analysis

Oct 02, 2024 Malware Analysis / Threat Detection
Dynamic malware analysis is a key part of any threat investigation. It involves executing a sample of a malicious program in the isolated environment of a malware sandbox to monitor its behavior and gather actionable indicators. Effective analysis must be fast, in-depth, and precise. These five tools will help you achieve it with ease. 1. Interactivity Having the ability to interact with the malware and the system in real-time is a great advantage when it comes to dynamic analysis. This way, you can not only observe its execution but also see how it responds to your inputs and triggers specific behaviors.  Plus, it saves time by allowing you to download samples hosted on file-sharing websites or open those packed inside an archive, which is a common way to deliver payloads to victims. The initial phishing email containing the malicious pdf and password for the archive Check out this sandbox session in the ANY.RUN sandbox that shows how interactivity is used for analyzing th...

Cybercriminals Target Polish Businesses with Agent Tesla and Formbook Malware

Cybercriminals Target Polish Businesses with Agent Tesla and Formbook Malware

Jul 30, 2024 Malware / Cyber Threat
Cybersecurity researchers have detailed widespread phishing campaigns targeting small and medium-sized businesses (SMBs) in Poland during May 2024 that led to the deployment of several malware families like Agent Tesla , Formbook , and Remcos RAT . Some of the other regions targeted by the campaigns include Italy and Romania, according to cybersecurity firm ESET. "Attackers used previously compromised email accounts and company servers, not only to spread malicious emails but also to host malware and collect stolen data," ESET researcher Jakub Kaloč said in a report published today. These campaigns, spread across nine waves, are notable for the use of a malware loader called DBatLoader (aka ModiLoader and NatsoLoader) to deliver the final payloads. This, the Slovakian cybersecurity company said, marks a departure from previous attacks observed in the second half of 2023 that leveraged a cryptors-as-a-service (CaaS) dubbed AceCryptor to propagate Remcos RAT (aka Resc...

JAVS Courtroom Recording Software Backdoored - Deploys RustDoor Malware

JAVS Courtroom Recording Software Backdoored - Deploys RustDoor Malware

May 24, 2024 Supply Chain Attack / Malware
Malicious actors have backdoored the installer associated with courtroom video recording software developed by Justice AV Solutions (JAVS) to deliver malware that's associated with a known implant called RustDoor. The software supply chain attack, tracked as CVE-2024-4978 (CVSS score: 8.7), impacts JAVS Viewer v8.3.7, a component of the  JAVS Suite 8  that allows users to create, manage, publish, and view digital recordings of courtroom proceedings, business meetings, and city council sessions. Cybersecurity firm Rapid7  said  it commenced an investigation earlier this month after discovering a malicious executable called "fffmpeg.exe" (note the three Fs) in the Windows installation folder of the software, tracing it to a binary named "JAVS Viewer Setup 8.3.7.250-1.exe" that was downloaded from the official JAVS site on March 5, 2024. "Analysis of the installer JAVS Viewer Setup 8.3.7.250-1.exe showed that it was signed with an unexpected Authenticode ...
How to Conduct Advanced Static Analysis in a Malware Sandbox

How to Conduct Advanced Static Analysis in a Malware Sandbox

Apr 18, 2024 Malware Analysis / Threat Detection
Sandboxes are synonymous with dynamic malware analysis. They help to execute malicious files in a safe virtual environment and observe their behavior. However, they also offer plenty of value in terms of static analysis. See these five scenarios where a sandbox can prove to be a useful tool in your investigations. Detecting Threats in PDFs PDF files are frequently exploited by threat actors to deliver payloads. Static analysis in a sandbox makes it possible to expose any threat a malicious PDF contains by extracting its structure. The presence of JavaScript or Bash scripts can reveal a possible mechanism for downloading and executing malware.  Sandboxes like ANY.RUN also allows users to scrutinize URLs found in PDFs to identify suspicious domains, potential command and control (C2) servers, or other indicators of compromise. Example: Static analysis of a PDF file in ANY.RUN Interactivity allows our users to manipulate files within a VM as they wish, but static Discovery off...
Decoy Microsoft Word Documents Used to Deliver Nim-Based Malware

Decoy Microsoft Word Documents Used to Deliver Nim-Based Malware

Dec 22, 2023 Social Engineering / Malware Analysis
A new phishing campaign is leveraging decoy Microsoft Word documents as bait to deliver a backdoor written in the  Nim programming language . "Malware written in uncommon programming languages puts the security community at a disadvantage as researchers and reverse engineers' unfamiliarity can hamper their investigation," Netskope researchers Ghanashyam Satpathy and Jan Michael Alcantara  said . Nim-based malware has been a rarity in the threat landscape, although that has been slowly changing in recent years as attackers continue to either develop custom tools from scratch using the language or port existing versions of their nefarious programs to it. This has been demonstrated in the case of loaders such as  NimzaLoader ,  Nimbda ,  IceXLoader , as well as ransomware families tracked under the names  Dark Power  and  Kanti . The attack chain documented by Netskope begins with a phishing email containing a Word document attachment that, when...
How to Analyze Malware’s Network Traffic in A Sandbox

How to Analyze Malware's Network Traffic in A Sandbox

Dec 13, 2023 Threat Intelligence / Malware Analysis
Malware analysis encompasses a broad range of activities, including examining the malware's network traffic. To be effective at it, it's crucial to understand the common challenges and how to overcome them. Here are three prevalent issues you may encounter and the tools you'll need to address them. Decrypting HTTPS traffic Hypertext Transfer Protocol Secure (HTTPS), the protocol for secure online communication, has become a tool for malware to conceal their malicious activities. By cloaking data exchange between infected devices and command-and-control (C&C) servers, malware can operate undetected, exfiltrating sensitive data, installing additional payloads, and receiving instructions from the operators. Yet, with the right tool, decrypting HTTPS traffic is an easy task. For this purpose, we can use a man-in-the-middle (MITM) proxy. The MITM proxy works as an intermediary between the client and the server, intercepting their communication. The MITM proxy aids analy...
