2024 had its fair share of high-profile cyber attacks, with companies as big as Dell and TicketMaster falling victim to data breaches and other infrastructure compromises. In 2025, this trend will continue. So, to be prepared for any kind of malware attack, every organization needs to know its cyber enemy in advance. Here are 5 common malware families that you can start preparing to counter right now. Lumma Lumma is a widely available malware designed to steal sensitive information. It has been openly sold on the Dark Web since 2022. This malware can effectively collect and exfiltrate data from targeted applications, including login credentials, financial information, and personal details. Lumma is regularly updated to enhance its capabilities. It can log detailed information from compromised systems, such as browsing history and cryptocurrency wallet data. It can be used to install other malicious software on infected devices. In 2024, Lumma was distributed through various methods...

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...

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...

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...

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 ...

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...
