Welcome to this week’s Threat Intel Newsletter. In this edition, the common thread is that compromise is increasingly happening through places defenders are forced to trust: edge infrastructure, virtualization layers, software update paths, and extension ecosystems. We break down China-linked targeting of Singapore’s telecom sector and leaked evidence

Welcome to this week’s Threat Intel Newsletter. This week we cover the most urgent threats where exploitation is happening fast and at scale. We start with mass exploitation of Ivanti EPMM—driven largely by a single bulletproof-hosted IP. Then we explain how trust is being abused in modern workflows, including

This week’s threat landscape highlights a sharp mix of ransomware and extortion pressure, credential-driven breaches, and active exploitation of high-impact enterprise and management-plane vulnerabilities. Healthcare and service providers remain prime targets, while phishing and social engineering continue to enable account takeovers and sensitive data exposure. At the same time,

This week’s newsletter centers on how attackers (and platforms) are increasingly using “quiet” collection and trust abuse to gain leverage—ranging from subtle tracking and data leakage (like extension fingerprinting and exposed API keys), to high-impact compromises and extortion, to social-engineering and supply-chain tactics that turn everyday tools and

Last week’s stories highlight a clear trend: attackers are succeeding by moving faster than organizations can patch and by targeting the areas that most often get overlooked—third‑party software and dependencies, exposed admin/management systems, and credentials/API keys. We’re seeing this play out in several ways:

If this edition of the newsletter has a single recurring theme, it’s that the systems and institutions we trust to keep us secure are themselves becoming the attack surface.

The first week of June makes one thing clear: attackers are targeting trust itself — in AI platforms, CI/CD pipelines, package provenance, MFA, and legacy patch status. AI is being weaponized faster than it’s being defended. Sophos uncovered an AI-assisted ransomware lab using Cursor and Claude Opus to

This week’s roundup is dominated by one overarching story: AI has become both the weapon and the target.

The week’s biggest theme is the weaponization of AI: attackers ran a botnet through Google’s Gemini CLI, hid malicious commands in images to fool AI code reviewers, and planted false memories in AI assistants — a signal that AI agents now need their own security controls. Alongside this, a
