DragonForce Ransomware Exploited Microsoft Teams to Hide in Attack Against Major Company

DragonForce ransomware operators leveraged Microsoft Teams to conceal their command and control communications during an attack on a major organization, exploiting a Teams visitor token to evade detection. By disguising malicious activity as legitimate Teams traffic, the attackers were able to obscure their presence from security defenses monitoring network communications.

FishMonger’s arsenal upgraded: SprySOCKS for Windows

ESET researchers have identified SprySOCKS for Windows, an upgraded backdoor in FishMonger's toolkit that leverages a kernel driver to achieve enhanced stealth capabilities. The use of kernel-level access represents a significant evolution in the malware's evasion techniques, making detection and removal more challenging for traditional security tools.

EvilTokens: A phishing attack that doesn’t steal your password

A newly discovered phishing kit called EvilTokens exploits Microsoft's legitimate authentication mechanisms to compromise accounts while bypassing traditional password theft and fake login page detection. The attack manipulates the authentication flow itself, allowing attackers to gain access without needing to intercept credentials or deploy convincing counterfeit login interfaces.

00:00 - Introduction 01:00 - Start of nmap 02:10 - Finding some CVE's in FontTools, but doing more recon on the site before we dive too deep 06:30 - Enumerating the website is flask based upon error message (cookie works too) 09:20 - Trying to create an error message which could leak information about the server like its local path 11:30 - Taking a look at portal.variatype.htb which shows it is PHP 13:50 - Gobuster found a .git, running git-dumper to get the source 15:30 - Finding a File Disclosure in the PHP App because the ../ removal was not recursive 20:30 - Updating the FontTools script to put a reverse shell in, then using it to upload a php reverse shell to the portal 22:00 - Reverse shell returned 22:30 - Looking at the sudoers file, we can't read it but the metadata is a treasure trove of information. Looking at timestamps, doing some filtering getting nothing 26:30 - Using docker to spin up a debian image quickly, looking at the size of the default sudoers file and then comparing it to the box to see it has likely been modified 28:00 - Using find to look for files owned by steve, finding a backup script. It uses FontForge which has a CVE. We can put a malicious archive file and get RCE 37:00 - Shell returned as Steve 39:00 - Looking at the validator python script, first thought with symlinks won't work because we don't own the plugin directory 41:30 - Finding a CVE within SetupTools, using it to write an SSH Key

Factoring "short-sleeve" RSA keys with polynomials

Researchers discovered hundreds of "short-sleeve" RSA and DSA keys with biased bit patterns that could be quickly factored using a novel polynomial-based cryptanalytic technique. The vulnerability, traced to a type mismatch bug in CompleteFTP versions 10.0.0–12.0.0 (RSA) and 10.0.0–23.0.4 (DSA), affected 603 unique RSA keys and 74 DSA keys; EnterpriseDT has released detection and remediation tools for affected users. The research highlights how structural weaknesses in cryptographic implementations can enable practical attacks and underscores the importance of using standard cryptographic libraries rather

The June 2026 Security Update Review

Microsoft and Adobe released record-breaking security updates in June 2026, with Microsoft patching 208 CVEs—the largest monthly release since tracking began in 2017—while Adobe issued 11 bulletins addressing 123 vulnerabilities. Critical priorities include Microsoft's CVSS 9.8 kernel and HTTP.sys remote code execution flaws that are wormable, a CVSS 10 Azure HorizonDB elevation of privilege, and Adobe's CVSS 10 Campaign Classic bugs, along with multiple Secure Boot vulnerabilities that could allow untrusted code execution at boot time.

Defend against frontier cyber models: Cloudflare's architecture as customer zero

In our post about Project Glasswing, we made the argument that the architecture around a vulnerability matters more than the speed of the patch. Here we walk through what that architecture looks like, the threats it defends against, and how we run it ourselves as Cloudflare's customer zero.
