Extremely Massive Galaxy ProtoSupercluster Smashes Distance Records to a ‘clusterofclusters’ of galaxies has a mass 5000 times that of the Milky Way and lies in one of the densest regions of the cosmic web ever observed

An international team of astronomers has discovered the most distant progenitor to a galaxy supercluster ever. The discovery supports existing theories of how galaxy clusters evolve, and reveals how they are connected to the larger cosmic web. The study relies largely on data from the ODIN survey, conducted with the U.S. Department of Energy-fabricated Dark Energy Camera on the U.S. National Science Foundation Víctor M. Blanco 4-meter Telescope in Chile.

Galaxy clusters are the most massive gravitationally bound structures in the Universe. These colossal groupings of hundreds to thousands of galaxies span millions of light-years. They are held together by large concentrations of dark matter, which serves as the building block for the larger structure of the Universe.

Clusters that scientists observe relatively near to us in space and time are mature structures that evolved from what are known as ‘protoclusters.’ These protoclusters are enormous, loosely bound collections of galaxies that are in the process of merging together but have yet to settle into a stable cluster. By studying very distant protoclusters that formed when the Universe was relatively young, scientists can understand how modern galaxy clusters grew and evolved over time.

PaperCut Attacker Uses Hundreds of AI Agents to Compromise 440+ Instances

A suspected Russian-speaking cyber actor has been attributed to the use of artificial intelligence (AI) to devise exploits targeting a recently disclosed pair of security flaws in PaperCut NG/MF and break into hundreds of instances.

According to independent reports from Blackpoint Cyber and GreyNoise, the activity originates from “45.142.193[.]132,” an IP address that has been linked to unauthorized port scanning and brute-force attack attempts in recent weeks. It’s worth noting the same IP address was also flagged by Arctic Wolf in connection with the exploitation activity last week.

“At this time, we cannot confirm the exact end goal of this campaign,” Nevan Beal, principal MDR analyst at Blackpoint, told The Hacker News. “The threat actor’s methodology is consistent with initial-access activity, but we do not yet have sufficient evidence to confirm whether they are operating as an initial access broker.”

New Android malware encrypts files, steals data, and harasses victims

A new Android malware strain called Mantax Otax combines ransomware and spyware capabilities to encrypt files, steal sensitive data, and spam and harass victims.

Indonesian operators distribute the malware through malicious APKs hosted outside Google Play, targeting users with phishing and social engineering messages.

After installation, the malware requests permission to use the Accessibility service, which gives it extensive control over compromised devices.

Microsoft Excel KB5002914 update breaks copy and paste for some users

Microsoft Excel users report that this week’s KB5002914 Office security update is breaking copy-and-paste operations and formula dragging, with affected users saying that removing or rolling back the update restores normal functionality.

Microsoft released the security update this week as part of its September 2026 Patch Tuesday, and reports of the problem soon appeared on both Reddit and the Microsoft Q&A forums.

“It seems that security update kb5002914 might have bricked autofill and copy paste in Excel 2016,” a Reddit user reported.
