Kali Linux 2025.4 released with 3 new tools, desktop updates

Kali Linux has released version 2025.4, its final update of the year, introducing three new hacking tools, desktop environment improvements, the preview of Wifipumpkin3 in NetHunter, and enhanced Wayland support.

Kali Linux is a distribution designed for cybersecurity professionals and ethical hackers to perform red-teaming, penetration testing, security assessments, and network research.

The distribution is available as an installable operating system or a live environment and supports a wide range of hardware, including Raspberry Pi devices and compatible Android phones through Kali NetHunter.

New Windows RasMan zero-day flaw gets free, unofficial patches

Free unofficial patches are available for a new Windows zero-day vulnerability that allows attackers to crash the Remote Access Connection Manager (RasMan) service.

RasMan is a critical Windows system service that starts automatically, runs in the background with SYSTEM-level privileges, and manages VPN, Point-to-Point Protocol over Ethernet (PPoE), and other remote network connections.

ACROS Security (which manages the 0patch micropatching platform) discovered a new denial-of-service (DoS) flaw while looking into CVE-2025–59230, a Windows RasMan privilege escalation vulnerability exploited in attacks that was patched in October.

Google is shutting down its dark web report feature in January

Google is discontinuing its “dark web report” security tool, stating that it wants to focus on other tools it believes are more helpful.

Google’s dark web report tool is a security feature that notifies users if their email address or other personal information was found on the dark web.

After Google scans the dark web and identifies your personal information, it will notify you where the data was found and what type of data was exposed, encouraging users to take action to protect their data.

Genie 3: Creating dynamic worlds that you can navigate in real-time

Genie 3 is a world builder powered by generative AI. It appears that it could in principle be built into a game engine.

One thing I’d like to do is have procedural generation as the backbone, and have generative AI modify things further that regular proc-gen textures just are not able to accomplish.

Introducing Genie 3, a general purpose world model that can generate an unprecedented diversity of interactive environments. Given a text prompt, Genie 3 can generate dynamic worlds that you can navigate in real time at 24 frames per second, retaining consistency for a few minutes at a resolution of 720p.

Our team has been pioneering research in simulated environments for over a decade, from training agents to master real-time strategy games to developing simulated environments for open-ended learning and robotics. This work motivated our development of world models, which are AI systems that can use their understanding of the world to simulate aspects of it, enabling agents to predict both how an environment will evolve and how their actions will affect it.

A grad student’s wild idea triggers a major aging breakthrough

Senescent “zombie” cells are linked to aging and multiple diseases, but spotting them in living tissue has been notoriously difficult. Researchers at Mayo Clinic have now taken an inventive leap by using aptamers—tiny, shape-shifting DNA molecules—to selectively tag these elusive cells. The project began as an offbeat conversation between two graduate students and quickly evolved into a collaborative, cross-lab effort that uncovered aptamers capable of binding to unique surface proteins on senescent cells.

Abstract: Helping cancer lose its grip

Here, Pengda Liu & team show SPOP inhibitors act as molecular glue degraders, stabilizing and activating STING to enhance immunotherapy in melanoma mouse models:

The figure shows the SPOP inhibitor 6lc reduces CBX4 and BMI1 foci, while ectopic CBX4 restores BMI1 foci and H2AX interactions.

Role of brain’s immune system in social withdrawal during sickness

“I just can’t make it tonight. You have fun without me.” Across much of the animal kingdom, when infection strikes, social contact shuts down. A new study details how the immune and central nervous systems implement this sickness behavior.

It makes perfect sense that when we’re battling an infection, we lose our desire to be around others. That protects them from getting sick and lets us get much needed rest. What hasn’t been as clear is how this behavior change happens.

In the research published in Cell, scientists used multiple methods to demonstrate causally that when the immune system cytokine interleukin-1 beta (IL-1β) reaches the IL-1 receptor 1 (IL-1R1) on neurons in a brain region called the dorsal raphe nucleus, that activates connections with the intermediate lateral septum to shut down social behavior.

“Our findings show that social isolation following immune challenge is self-imposed and driven by an active neural process, rather than a secondary consequence of physiological symptoms of sickness, such as lethargy,” said study co-senior author.

Neurons use physical signals, not electricity, to stabilize communication

Every movement you make and every memory you form depends on precise communication between neurons. When that communication is disrupted, the brain must rapidly rebalance its internal signaling to keep circuits functioning properly. New research from the USC Dornsife College of Letters, Arts and Sciences shows that neurons can stabilize their signaling using a fast, physical mechanism—not the electrical activity scientists long assumed was required.

The discovery, published recently in Proceedings of the National Academy of Sciences, reveals a system that doesn’t depend on the flow of charged particles to maintain signaling when part of a synapse—the junction between neurons—suddenly stops working.

Maintaining this balance between neurons is essential for muscle control, learning and overall brain health. Failure to maintain this “homeostasis” has been linked to neurological conditions such as epilepsy and autism.

Real-time tracking of mRNP complex assembly reveals various mechanisms that synergistically enhance translation repression

Using single-molecule fluorescence microscopy, Payr et al. reveal how multiple RNA-binding proteins synergize to repress translation. One RNA-binding protein binds via facilitated diffusion, recruits other proteins with highly accelerated on rate, and gets stabilized by several co-factors. The findings highlight various mRNP assembly mechanism as key to efficient translational control.
