Four alleged European hackers have been arrested in Phuket for deploying ransomware on the networks of 17 Swiss firms. The suspects are accused of causing significant damage and stealing $16 million in Bitcoins from 1,000 global victims.
The TL;DR is that this time, we ended up discovering ~150 Amazon S3 buckets that had previously been used across commercial and open source software products, governments, and infrastructure deployment/update pipelines - and then abandoned.
Naturally, we registered them, just to see what would happen - “how many people are really trying to request software updates from S3 buckets that appear to have been abandoned months or even years ago?”, we naively thought to ourselves.

A threat actor has infected the website of Casio UK and 16 other victims with a web skimmer that altered the payment flow to harvest and exfiltrate visitors’ information, web security provider Jscrambler reports.
British-based engineering firm IMI plc has disclosed a security breach after unknown attackers hacked into the company's systems.
Chainalysis says a combination of law enforcement actions and better defenses led to less money going out to ransomware actors.
In September of 2024 while on a customer assigment I encountered the “Network Configuration Operators” group, a so called builtin group of Active Directory (default). As I had never heard of or encountered this group membership before, it sprung to eye immediately. Initially I tried to look up if it had any security implications, like its more known colleagues DNS Admins and Backup Operators, but to no avail. Surpisingly little came up about the group but I couldn’t help myself from probing further. This led me down the rabbithole of Registry Database access control lists and possibilities of weaponization, culminating with the discovery of CVE-2025-21293. Before we move along to the body of work, I have to give out a special thanks to Clément Labro, who initially did the heavy lifting of finding a way to weaponize performancecounters. (This will hopefully make more sense by the end of the article) and my colleagues at ReTest Security ApS, who have provided me with knowledge in the field and the oppertunity to put it to use.
The ZDI team offers an analysis of how CVE-2025-0411, a zero-day vulnerability in 7-Zip was actively exploited to target Ukrainian organizations through spear-phishing and homoglyph attacks.
In a first-of-its-kind report, the US government has revealed that it disclosed 39 zero-day software vulnerabilities to vendors or the public in 2023 for the purpose of getting the vulnerabilities patched or mitigated, as opposed to retaining them to use in hacking operations.
It’s the first time the government has revealed specific numbers about its controversial Vulnerabilities Equities Process (VEP) — the process it uses to adjudicate decisions about whether zero-day vulnerabilities it discovers should be kept secret so law enforcement, intelligence agencies, and the military can exploit them in hacking operations or be disclosed to vendors to fix them. Zero-day vulnerabilities are security holes in software that are unknown to the software maker and are therefore unpatched at the time of discovery, making systems that use the software at risk of being hacked by anyone who discovers the flaw.
A code analysis by the BSI shows that two-factor authentication could be bypassed in Nextcloud Server. Passwords were also stored in plain text.
Bohemia Interactive has issued a statement in response to the Arma Reforger and DayZ DDOS attack.
The North Korean hacking group known as Kimsuky was observed in recent attacks using a custom-built RDP Wrapper and proxy tools to directly access infected machines.
Habib Mohammadi reports:
A group of unidentified hackers has breached the Taliban’s databases, leaking documents from 21 ministries and government agencies, some of which appear to be classified, according to reports circulating online.
The leaked files reportedly include documents from the Taliban-controlled ministries of finance, justice, foreign affairs, information and culture, telecommunications, and mining, as well as the Supreme Court and the Ministry for the Promotion of Virtue and Prevention of Vice.
The hackers have published hundreds of these documents on a website called “Talibleaks.”
After a ransomware attack on the state's health and social services system, Deloitte is giving Rhode Island $5 million to help cover expenses.
The eSentire Threat Response Unit (TRU) revealed that threat actors are actively exploiting a six-year-old IIS vulnerability.
Microsoft Threat Intelligence observed limited activity by an unattributed threat actor using a publicly available, static ASP.NET machine key to inject malicious code and deliver the Godzilla post-exploitation framework. In the course of investigating, remediating, and building protections against this activity, we observed an insecure practice whereby developers have incorporated various publicly disclosed ASP.NET machine keys from publicly accessible resources, such as code documentation and repositories, which threat actors have used to launch ViewState code injection attacks and perform malicious actions on target servers.
Cisco has fixed two critical Identity Services Engine (ISE) vulnerabilities that can let attackers with read-only admin privileges bypass authorization and run commands as root.
