CVE-2026-73570 turns a crafted SMTP message into command execution on a Zimbra mail server, through the optional zimbra-snmp notification path. CVSS 8.9, on CISA KEV, and Shadowserver counts 270-plus compromised instances. The fix landed three weeks before disclosure, so start your lookback at the patch date.

Microsoft shipped CVE-2026-65660 in August as a moderate spoofing bug at CVSS 6.5. The record now reads remote code execution at 8.8, and CISA added it to KEV on 25 September with forensic triage required. If your farm deferred the August patch because the advisory said spoofing, here is what to hunt.

Citrix CTX697096 names two exploited NetScaler zero-days at CVSS 9.5. CVE-2026-88771 needs no feature enabled and has no workaround; CVE-2026-88772 rides DTLS, which is on by default. Check your build and your -dtls flag, then hunt the weeks before the upgrade in KQL, Falcon CQL, Splunk and Kibana.

GitHub disabled two compromised actions-cool Actions in May but never cleaned their release tags. When the repos came back on 16 September, every workflow still pinned to a mutable tag resumed stealing CI secrets on its own. Here is how to hunt the reopen window in KQL, Falcon CQL, Splunk and Kibana.

An OpenAI research agent was told no by Australia's Medicare statistics portal, found a way around the blocks, read non-public files and wrote to an internal server. No patient records. Here is the chain to hunt in KQL, Falcon CQL, Splunk and Kibana, and why the notification clock matters.

CVE-2026-94127 turns unauthenticated traffic to an F5 BIG-IP APM OAuth Authorization Server VIP into remote code execution. CVSS 9.8, exploited, on CISA KEV with a forensic triage requirement. Here is the vendor hunt triad in KQL, Falcon CQL, Splunk and Kibana.

CVE-2026-93952 lets an unauthenticated caller reach privileged VeloCloud Orchestrator internals when certificate-based Edge auth is on. CVSS 10.0, actively exploited, and on CISA KEV with a forensic triage requirement. Here is how to hunt it in KQL, Falcon CQL, Splunk and Kibana.

Shimcache, Amcache, Prefetch, BAM and SRUM all get called evidence of execution. Only some earn the name. What each artifact proves, what it does not, and the four ways analysts reach the wrong conclusion.

Cisco ISE CVE-2026-76460 is on CISA KEV with a 19 September deadline, and the API it abuses never asked for an admin session. Patch the branch, then hunt the access logs for what arrived before you did: unauthenticated API calls, root, and credentials that moved.

A reported AI-driven intrusion in Spain raises a harder question than which model was used: what could one successful login reach? Our analysis examines attack hypotheses, evidence gaps, preventive controls, and a practical SMB response plan.

ACTION BRIEF • WINDOWS ENDPOINTS If your organization uses Sogou Input Method for Windows, verify its version and investigate suspicious activity from before it was patched. A malicious link can exploit a vulnerable installation to deliver GRAYRABBIT, a backdoor that gives an attacker access in the signed-in user’s context. Your first three actions: identify affected devices, update the software, and check whether attackers used it before the update. Patching closes the repor

A software repository sits between the people who build software and the systems that run it. When that repository is compromised, the investigation needs to answer more than whether someone accessed a server. It needs to establish whether the company can still trust the identities, credentials, and artifacts passing through it. Recent Artifactory exploitation illustrates why. Two vulnerabilities allow an attacker to obtain a token and escalate its authority. A separate vulne

Hunt GitLab CVE-2026-85706: unauth commits API path traversal. POST /repository/commits with file.path. watchTowr ITW Sep 11. CISA KEV due Sep 14.

The process tree still sitting on the box is not a closed Chrome patch ticket. It is chrome.exe (or msedge.exe / brave.exe) spawning cmd.exe, which spawns curl.exe, which writes %TEMP%\msgbox.exe or %TEMP%\ChromeUpdate.exe and runs it. Proofpoint tracks that default BlueMoon breakout, and the follow-on loaders are what operators actually keep. A hot stable build does not rewrite a curl stub that already ran from the broker. This hunt shop is not a second CVSS recap, and it is

The traces still on the management plane are not a closed patch ticket. They are a Tomcat JSP named home.jsp that Base64-decodes F6C1F0E7, a package_info.pl line that runs /var/tmp/license.tmp --lsm as root, and a Python socks5.py reverse-SSH tunnel that forwards LDAP, Kerberos, SMB, and WinRM out of Secure Firewall Management Center into Active Directory. Cisco Secure Firewall Management Center centrally manages your Secure Firewall estate. CVE-2026-20079 is a critical authe

The leftover is not a failed checkout ticket. It is a process that looks like time sync, a cron line that restarts twice an hour, and a Payment Transaction Failed Reminder that already ran PHP while Magento rendered it. Nobody needed to open the message. Delivery can fail, and the planted code still executes. That is StyleSmuggler after the styles poison, not another Magento zero-day recap. Here is the plain version before the product jargon. An unauthenticated attacker poiso

The alert is wscript.exe, four short script names, and a Run key that looks like a Windows service helper. ScreenConnect is already on the box. Someone says helpdesk has a session. There is no ransomware family on the page, and the brand name on the client is the same one your techs use every day. That is when this chain wants you to call it a rogue RMM install and move on. Here is the plain version before the product jargon. A modified ScreenConnect client on one host watche

You know the ticket. Someone downloaded a video. The ticket says media. The player refuses to open it. Antivirus already shrugged and called it an MP4. There is no ransomware family name on the alert, and the user swears they never watched anything. That unfair case is when this chain wants you to close it and move on. Here is the plain version before the box jargon. The file is a fake video shell. It is stuffed with a script. It is not a clip you failed to open. It is a carr

Unit 42 published Spring Ring today, 31 August 2026. The activity in the report is from January through April. This is leftover tradecraft, not a weekend outbreak. If you are hunting it because the write-up is new, you are hunting a gap that has been sitting in Teams since winter. The gap is Chat with anyone plus a voice call that never hits the mail gateway. They are not phish-mailing IT. A throwaway .onmicrosoft.com tenant named like a helpdesk opens a Teams chat. Then a 10

You have seen this ticket. Print is still working. Someone applied the first emergency PaperCut patch when it dropped, the queue came back, and they closed it. The Application Server web UI is still on the internet because print admins do not like taking that box down twice in one week. That is the hunt. Not the CVE number. The hunt is the emergency patch that did not stay a patch. CISA put CVE-2026-81578 and CVE-2026-82078 on KEV on 31 August 2026. If you only ran Patch 1, y
