Imagine you're considering a new car for your family. Before making a purchase, you evaluate its safety ratings, fuel efficiency, and reliability. You might even take it for a test drive to ensure it meets your needs. The same approach should be applied to software and hardware products before integrating them into an organization's environment. Just as you wouldn't buy a car without knowing its safety features, you shouldn't deploy software without understanding the risks it introduces. The Rising Threat of Supply Chain Attacks Cybercriminals have recognized that instead of attacking an organization head-on, they can infiltrate through the software supply chain—like slipping counterfeit parts into an assembly line. According to the 2024 Sonatype State of the Software Supply Chain report , attackers are infiltrating open-source ecosystems at an alarming rate, with over 512,847 malicious packages detected last year alone—a 156% increase from the previous year. Traditional sec...

Cybersecurity researchers have uncovered two malicious machine learning (ML) models on Hugging Face that leveraged an unusual technique of "broken" pickle files to evade detection. "The pickle files extracted from the mentioned PyTorch archives revealed the malicious Python content at the beginning of the file," ReversingLabs researcher Karlo Zanki said in a report shared with The Hacker News. "In both cases, the malicious payload was a typical platform-aware reverse shell that connects to a hard-coded IP address." The approach has been dubbed nullifAI, as it involves clearcut attempts to sidestep existing safeguards put in place to identify malicious models. The Hugging Face repositories have been listed below - glockr1/ballr7 who-r-u0000/0000000000000000000000000000000000000 It's believed that the models are more of a proof-of-concept (PoC) than an active supply chain attack scenario. The pickle serialization format, used commonly for dis...

You arrive at the office, power up your system, and panic sets in. Every file is locked, and every system is frozen. A ransom demand flashes on your screen: "Pay $2 million in Bitcoin within 48 hours or lose everything." And the worst part is that even after paying, there's no guarantee you'll get your data back. Many victims hand over the money, only to receive nothing in return, or worse, get hit again. This isn't a rare case. Ransomware attacks are crippling businesses worldwide, from hospitals and banks to small companies. The only way to stop the damage is by proactively analyzing suspicious files and links before they can be executed. Below, we break down the top three ransomware families active in 2025: LockBit, Lynx, and Virlock, and find out how interactive analysis helps businesses detect and stop them before it's too late. LockBit: Teasing a Comeback in 2025 LockBit is one of the most notorious ransomware groups, known for its highly efficient encryption, do...

A previously unknown threat actor has been observed copying the tradecraft associated with the Kremlin-aligned Gamaredon hacking group in its cyber attacks targeting Russian-speaking entities. The campaign has been attributed to a threat cluster dubbed GamaCopy , which is assessed to share overlaps with another hacking group named Core Werewolf , also tracked as Awaken Likho and PseudoGamaredon. According to the Knownsec 404 Advanced Threat Intelligence team, the attacks leverage content related to military facilities as lures to drop UltraVNC, allowing threat actors to remotely access the compromised hosts. "The TTP (Tactics, Techniques, and Procedures) of this organization imitates that of the Gamaredon organization which conducts attacks against Ukraine," the company said in a report published last week. The disclosure arrives nearly four months after Kaspersky revealed that Russian government agencies and industrial entities have been the target of Core Werewolf, ...

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...
