A Systemd Generator Executes Before Your Logging Is Up. Catch the Write, Not the Run

System-level systemd generators run as root at the earliest moment of boot, before auditd, before the EDR agent, before your normal journald/syslog/audit telemetry is reliably up. You will never see the execution. Here is how to build the detection that actually works — file writes and baseline reconciliation — and what breaks it the first week.

CVE-2026-3055 Bleeds Session Tokens Your NetScaler Barely Logs. The Detection Lives Off the Box

The NetScaler memory-overread class has a third sequel. CVE-2026-3055 leaks session tokens through an endpoint the appliance barely logs — so its own logs won’t prove you’re clean, and the detection has to move upstream to the response size and downstream to the reused token, while patching does nothing to the sessions already bled.

The IKEv1 Bypass Is Client-Controlled. Check Point Logs the Login, Not the Vendor ID That Forged It

CVE-2026-50751 lets an unauthenticated client flip a Check Point gateway’s certificate-verification flag using a crafted IKEv1 vendor ID payload. The catch for defenders: the forged payload isn’t in your normal VPN security logs. The only artifact is a VPN session that came up when it shouldn’t have.

Your Device Code Flow Alert Fires on Every az login. The Signal Is the Broker Token, Not the Prompt

Device code phishing doesn’t defeat MFA — it redirects a legitimately MFA-completed sign-in — and the naive detection drowns in legitimate CLI traffic. The durable signal is the Authentication Broker redemption and the device registration that follows, and the real fix is a Conditional Access authentication-flows block.

ESXi Can Write Its Logs to a RAM Disk. Ransomware Counts on It

On an ESXi host without persistent scratch, /var/run/log lives on an in-memory ramdisk and evaporates at the next boot. Ransomware crews get the same effect for free — they power off, kill, or reboot the workloads before encrypting — which means your entire forensic timeline had to be forwarded off-box before the incident or it never existed at all.

A Federated Identity Credential Adds No Secret. Your Service Principal Persistence Alert Never Fires

Most SOCs detect service principal persistence by watching for “Add service principal credentials.” Federated identity credentials reach the same persistence with a different audit operation, on a different object, sometimes in a log source you never ingested.

Strong Certificate Mapping Only Helps If the CA Owns the SID. ESC16 Takes It Away

Microsoft’s strong certificate mapping enforcement finally landed, and where it’s genuinely in force it does close the naive implicit-mapping hole that made ADCS escalation trivial — a certificate with only a weak name is denied. ESC16 strips the CA-issued SID so the mapping decision falls to whatever’s left: on a compatibility-mode DC that’s weak SAN mapping, and even on a fully-enforced DC it’s an attacker-supplied SID-in-SAN URI the KDC treats as strong. The audit events you’d hunt it with are off by default.

Agent Memory Poisoning Survives the Session. The Detection Lives in the Write Path Nobody Logs

Single-turn prompt injection usually dies when the context window clears. Memory poisoning persists, fires weeks later, and hides in a memory-write event your platform was never built to emit as security telemetry. Here is what to instrument, what to detect, and what the first round of tuning gets wrong.

AppDomainManager Hijacking Hides in a Signed Binary. The Tell Is One Line of XML That Kills ETW

AppDomainManager hijacking loads attacker code into a Microsoft-signed .NET process before the app runs — and the same config file that does it can switch off the ETW telemetry your EDR depends on. The cleanest detection isn’t the dropped DLL. It’s the XML.

The DPRK Worker’s KVM Is Plugged Into Your Laptop, Not the Internet. Hunt the Sign-In Log Instead

North Korean IT workers don’t breach you — they get hired. The device fingerprint everyone reaches for is spoofable and behind home NAT. The detection that survives contact with production lives in your identity provider’s sign-in logs.
