The threat actor known as JADEPUFFER has been observed orchestrating destructive actions within a Microsoft Azure environment using compromised service principals. Microsoft, which is tracking the activity under the name Storm-3168 , has called it an evolution of the threat actor's tradecraft. The attack took place in early June 2026 over a period of about 18 hours. "The destructive operations were facilitated by compromising service principals and targeted Azure Storage Accounts, SQL databases, Key Vaults, Function Apps, recovery protection locks, Virtual Machines, and App Services," researchers Yossi Weizman and Tushar Mudi, along with the Microsoft Security Research team, said . JADEPUFFER was first documented by Sysdig, describing it as the first-ever ransomware operation run end-to-end with the help of a large language model (LLM). The agentic attack exploited a known security flaw in Langflow (CVE-2025-3248) to break in, harvested credentials, burrowed deepe...

This week, the dangerous stuff keeps arriving dressed as something boring. An update. A login box. A search answer. A coding tool. A link you have clicked a hundred times before. That is the thread running through the pile. Trusted paths get poisoned. Old bugs find new jobs. AI tools leak more than expected. Fake prompts look real enough. And some attacks barely need an exploit at all — just one weak setting or one person doing what the screen tells them. Nothing here looks especially dramatic. That is what makes it useful. The threats change every week. Subscribe, and we’ll alert you when each new ThreatsDay Bulletin is out.

Attackers keep finding new keys. The funny part is that defenders keep inventing where to store them. This week, those keys sit in AI tools, exposed services, old bugs, weak logins, and software sold like a monthly subscription. Some attacks use new tricks. Others just reuse what was already lying around. Both work often enough. So the threat landscape is not getting cleaner. It is just getting more places to make the same mistake. Here’s what showed up this week. The threats change every week. Subscribe, and we’ll alert you when each new ThreatsDay Bulletin is out.

Enterprises in Russia have emerged as the target of three threat activity clusters tracked as NightEagle , Hacking Cat , and Toy Ghouls , according to multiple reports from Kaspersky. The cybersecurity vendor said it has identified attacks mounted by NightEagle (aka APT-Q-95), a threat actor known to be active since at least 2023, that involve new techniques for persistence and lateral movement. "In most incidents, the attackers used compromised valid credentials to gain access to corporate VPNs," Kaspersky said in an analysis published today. "VPN connections originated from IP addresses in the Russian segment linked to Cloudflare WARP tunnels, as well as from IP addresses associated with European virtual infrastructure providers." The attacks, as highlighted in July 2025, involve the deployment of GhostContainer , a known modular backdoor that grants the operators complete access to a victim's Microsoft Exchange Server, as well as run arbitrary code, ...

Cisco has revealed that three distinct threat clusters linked to ransomware and state-sponsored attacks have been exploiting two recently patched Secure Firewall Management Center (FMC) vulnerabilities. The attacks leverage CVE-2026-20079 (CVSS score: 10.0), an authentication bypass vulnerability in the web interface of FMC software that could allow an unauthenticated, remote attacker to bypass authentication and execute script files on an affected device to obtain root access to the underlying operating system. The second flaw under exploitation is CVE-2026-20316 (CVSS score: 5.3), which could allow an unauthenticated, remote attacker to log in to an affected device using a low-privilege account to access sensitive data within susceptible systems. It can be paired with other Cisco Secure FMC vulnerabilities to elevate privileges. Cisco Talos said it identified three clusters of post-compromise activity of FMC instances associated with state-sponsored and crimeware threat act...
