Kratos is a mature Phishing-as-a-Service operation impersonating Microsoft 365 login pages to steal credentials across US and European organizations. The kit uses legitimate platforms (SharePoint, Canva, Tilda) as intermediary redirect pages, Cloudflare Turnstile to block automated analysis, and PHP endpoints for credential exfiltration. Researchers identified three generations (V0, V1, V2) with distinct asset fingerprints and exfiltration code, and uncovered the operator panel with automated deployment, Telegram-based data delivery, and geographic restriction capabilities.

Kratos PhaaS Targets US and EU: How to Reduce Microsoft 365 Account Takeover Risk One Email Closer to the Edge: UNK_MassTraction & the Physics of Exploitation UNK_MassTraction, a suspected China-aligned threat cluster, has been exploiting chained n-day vulnerabilities in Roundcube mailservers (CVE-2024-42009 XSS followed by CVE-2025-49113 PHP deserialization) targeting physics and engineering departments at US and Canadian universities since May 2026. The campaign deploys a custom JavaScript credential stealer (IceCube), a webshell (SquareShell), and the VShell backdoor via an in-memory ELF loader, treating mailservers as edge devices for network pivot. The tooling demonstrates mature operational security including anti-forensics, fallback mechanisms, and process spoofing.
Famous Chollima Targets PHP Developers Through Compromised Packagist Package A targeted supply chain attack attributed to Famous Chollima compromised a development branch of the legitimate PHP package 'roberts/leads' on Packagist. The attackers injected an obfuscated JavaScript loader into a tailwind.js configuration file, which utilizes blockchain RPC infrastructure as a dead drop to retrieve and execute secondary payloads like DEV#POPPER RAT, likely as part of a Contagious Interview developer lure.
Laravel Lang Compromised with RCE Backdoor Across 700+ Versions A massive supply chain attack compromised over 700 historical versions of Laravel Lang packages, injecting an RCE backdoor via Composer's autoloader. The backdoor delivers a sophisticated, cross-platform PHP information stealer designed to harvest cloud credentials, CI/CD secrets, browser data, and local configuration files.
CVE-2026-9082: Mitigating a Critical SQL Injection Vulnerability in Drupal A critical SQL injection vulnerability (CVE-2026-9082) in Drupal core allows unauthenticated attackers to exfiltrate sensitive data or bypass authentication. The flaw specifically affects Drupal environments utilizing a PostgreSQL database backend alongside the JSON:API, Views, or Entity autocomplete modules, stemming from the improper sanitization of PHP array keys before they reach the database abstraction layer.
Packagist Urges Immediate Composer Update After GitHub Actions Token Leak A vulnerability in Composer causes it to inadvertently log GitHub Actions tokens and GitHub App installation tokens to stderr when token validation fails. This was triggered by a recent GitHub token format change, exposing credentials in CI/CD logs and requiring immediate updates to Composer versions 2.9.8, 2.2.28 LTS, or 1.10.28.
pnpm 11 Adds Supply Chain Protection Defaults for Minimum Release Age and Exotic Subdependencies The release of pnpm 11 introduces significant supply chain security enhancements, including a default 24-hour minimum release age for packages, the blocking of exotic subdependencies, and a streamlined allowBuilds model. These features are designed to mitigate rapid supply chain attacks, such as the recent Mini Shai-Hulud campaign, by restricting install-time execution and unexpected dependency sources.
Mini Shai-Hulud Spreads to Packagist: Malicious Intercom PHP Package Follows npm Compromise The Mini Shai-Hulud supply chain attack campaign has expanded into the PHP ecosystem by compromising the widely used intercom/intercom-php package on Packagist. The malicious artifact abuses Composer plugin execution to download the Bun runtime and execute an obfuscated JavaScript payload designed to harvest and exfiltrate sensitive credentials from developer environments and CI/CD pipelines.
Intelligence Center The Cisco Talos Year in Review highlights a shifting threat landscape where attackers leverage AI and rapid exploit development to target identity infrastructure and exposed vulnerabilities. Defenders are urged to prioritize identity protection, remediate internet-facing vulnerabilities, address legacy system risks, secure trust-brokering platforms, and focus on behavioral anomaly detection to identify post-compromise activity.
Introducing Reachability for PHP Socket.dev has launched an experimental PHP reachability analysis tool designed to reduce vulnerability alert fatigue. By performing deep static analysis of function-level call graphs, including complex PHP dispatch patterns, the tool determines whether known CVEs in dependencies are actually executable within an application's context.
Trailmark turns code into graphs Trail of Bits has released Trailmark, an open-source library that converts source code into queryable call graphs to enhance AI-assisted security analysis. By integrating with Claude Code, Trailmark enables advanced mutation testing triage, blast radius analysis, and the identification of architectural bottlenecks in cryptographic libraries.
North Korea’s Contagious Interview Campaign Spreads Across 5 Ecosystems, Delivering Staged RAT Payloads North Korea's Contagious Interview campaign has launched a coordinated supply chain attack across five major open-source ecosystems. The threat actors published malicious packages masquerading as legitimate developer tools that act as staged loaders to deliver remote access trojans (RATs) and infostealers to developer workstations.
6 Malicious Packagist Themes Ship Trojanized jQuery and FUNNULL Redirect Payloads Security researchers identified six malicious Composer packages on Packagist masquerading as OphimCMS themes. These packages contain trojanized JavaScript that executes client-side attacks, including URL exfiltration, ad injection, and redirects to gambling sites operated by the OFAC-sanctioned FUNNULL network.
Malicious Packagist Packages Disguised as Laravel Utilities Deploy Encrypted RAT Socket's Threat Research Team discovered a supply chain attack involving malicious Packagist packages that deploy an encrypted Remote Access Trojan (RAT). The packages, disguised as Laravel utilities, execute automatically upon application boot or class autoloading, granting the attacker full remote shell access, file manipulation, and system reconnaissance capabilities across Windows, macOS, and Linux environments.

AI Weaponization and Developer Supply Chain Attacks Redefine the Perimeter Attackers are aggressively targeting the software development process because compromising a single developer tool can unlock thousands of corporate networks. In parallel, artificial intelligence is collapsing the cost of attacks, allowing criminals to build convincing deepfakes and automated phishing campaigns in minutes. As a result, traditional security like multi-factor authentication is increasingly bypassed using tricks that steal active login sessions rather than passwords. These trends together suggest that relying on perimeter defenses and basic hygiene is no longer enough, as attackers hide inside trusted cloud services and legitimate software updates. This matters because organizations are losing visibility into where their sensitive data actually lives, especially as AI tools create hidden pathways into company systems. Defenders must shift their focus to monitoring user behavior after login and securing the automated systems that build their software. Watch for unusual activity in your developer tools and implement stricter checks on third-party software.
