AI Threat

The Machine Pulls the Trigger: Sysdig Documents JADEPUFFER, the First Ransomware Attack Run End-to-End by an AI Agent

Sysdig this week detailed JADEPUFFER, which it calls the first fully "agentic" ransomware operation — an intrusion executed from break-in to extortion by an AI agent rather than a human at a keyboard. The agent gained access through CVE-2025-3248, a missing-authentication flaw in an internet-facing Langflow instance that allows unauthenticated Python execution, then dumped the local database, harvested credentials and environment secrets, and enumerated a MinIO object store before pivoting to a production MySQL server running Alibaba Nacos.

There it ran a destructive database-extortion playbook: encrypting all 1,342 Nacos configuration items with MySQL's AES_ENCRYPT(), dropping the originals, and creating a README_RANSOM table holding the demand, a Bitcoin address, and a Proton Mail contact. The tell of automation was everywhere — self-narrating payloads full of natural-language reasoning and target prioritization no human types by hand, and a jump from a failed login to a working fix in 31 seconds. Forensic priority: preserve the agent's verbose command and reasoning artifacts, timeline the machine-speed activity, and capture database transaction logs before the dropped tables are gone for good.

Critical Infrastructure

AI-Crafted and Aimed at the Grid: Kaspersky Names "Armored Likho" Behind the BusySnake Stealer Hitting Power Operators

Kaspersky unmasked a previously undocumented espionage actor, Armored Likho, running an ongoing campaign against government agencies and electric-power operators across Russia, Kazakhstan, and Brazil. The chain abuses CVE-2025-9491, a Windows LNK UI-misrepresentation flaw, to fire an obfuscated PowerShell loader that shows a decoy document while staging BusySnake — a novel Python infostealer that lifts Chromium and Firefox passwords, session cookies and OTP codes, Telegram session data, and cryptocurrency wallets, then opens reverse SSH tunnels for remote access.

What sets the campaign apart is the tooling's fingerprint: Kaspersky assesses that the first-stage loaders and stagers were likely generated with AI assistance, betrayed by redundant comments and duplicated code blocks of the kind language models produce reflexively. Paired with Page 1's autonomous ransomware, it marks a week where AI is visibly moving from the lab into live operations against critical infrastructure. Forensic priority: parse the malicious LNK files for embedded commands, decode the staged PowerShell, and hunt reverse-SSH tunnels and Python-stealer persistence on grid and government hosts.

Threat Bulletin

ACTIVE EXPLOIT
CVE-2026-45659

Microsoft SharePoint Server — a remote code execution flaw arising from deserialization of untrusted data lets an attacker run code on the server; CVSS 8.8. Patched in May 2026 for Subscription Edition, 2019, and Enterprise 2016, it is now under active exploitation by financially motivated and ransomware crews; CISA added it to the KEV on July 1 with a July 4 federal deadline. Forensic Note: Review SharePoint ULS and IIS logs for anomalous deserialization requests, hunt web shells and new service accounts, and confirm the May 2026 patch is applied.

CRITICAL
CVE-2026-35616

Fortinet FortiClient EMS — a SQL injection flaw lets an unauthenticated attacker run unauthorized code or commands against the management server; CVSS 9.1. It was exploited this week to deploy the EKZ Stealer against an energy, utilities, and waste-sector target, harvesting Chromium and Firefox credentials and exfiltrating them over PowerShell — part of a wider wave of FortiGate-focused credential theft feeding INC and Lynx ransomware. Forensic Note: Audit FortiClient EMS query logs for injection strings, hunt PowerShell exfiltration and browser-credential access, and rotate every credential exposed to the appliance.

Friends Ransomware — Double Extortion With a .friends124 Twist

Profiled by CYFIRMA, Friends Ransomware encrypts victim data with strong cryptography and appends the .friends124 extension to affected files, then pressures targets by claiming sensitive information was exfiltrated before encryption — the hallmark of a double-extortion operation. Its steal-then-encrypt model keeps the leak-site threat alive even for victims with clean backups. Forensic Note: Identify the encryption onset from .friends124 timestamps, hunt the staging and exfiltration that precede encryption, and preserve ransom notes and any leak-site correspondence for scoping.
