- Engineer — Plan: TeamViewer is common in enterprise support tooling; the reversed-direction exploit (host attacking controller) is an unusual attack surface. No active exploitation or PoC reported, so update TeamViewer viewers to the patched version in your next patch cycle.
- SOC/IR — Learn: The host-to-viewer attack direction is a noteworthy technique shift for remote-access tools, but no IOCs, TTPs, or exploitation activity are reported — nothing actionable for detection or hunting at this time.
- Leader — Skip
- Engineer — Plan: Active exploitation of internet-exposed industrial controller remote management confirms real risk in OT environments. If you manage refrigeration, HVAC, or similar OT systems with vendor remote-management access, audit which maintenance firms hold credentials and whether those interfaces are network-segmented or publicly reachable.
- SOC/IR — Learn: No IOCs, ATT&CK mappings, or detection artifacts are published; the attack surface (Danfoss refrigeration controllers) falls outside typical enterprise IT/EDR visibility. Useful context for OT-adjacent hunting programs but yields no immediate detection work.
- Leader — Learn: Concrete example of third-party remote-access risk in OT environments causing material operational damage; worth referencing in future OT risk discussions, especially for leaders in retail, food, pharma, or cold-chain-dependent sectors. No immediate board-level action required for general enterprise leaders.
- Engineer — Learn: Illustrates real-world risk of internet-exposed OT equipment (Danfoss refrigeration controllers); no CVE or PoC disclosed, but engineers managing building management or refrigeration systems should audit whether similar controllers have remote access hardened or air-gapped.

- Engineer — Act: A public working exploit for a pre-auth root RCE means active exploitation risk is immediate; upgrade AnyDesk Linux to version 8.0.3 on all hosts and audit for any instances still running older versions.
- SOC/IR — Plan: No IOCs or active campaign reported yet, but working exploit publication typically precedes mass exploitation; build or tune detections for anomalous process spawning from the AnyDesk daemon on Linux endpoints and queue a hunt for lateral movement from remote-access tools.
- Leader — Plan: Confirm whether AnyDesk Linux is deployed in the environment and verify the patch is applied; the vendor’s deliberately vague changelog — no CVE, no security advisory — is a vendor-transparency red flag worth raising in your next vendor risk review.
- Engineer — Act: SMA1000 is a widely deployed remote-access appliance; active exploitation with a public PoC means the patch-window is effectively zero — apply the Tuesday release immediately and verify no unauthorized access occurred before patching.
- SOC/IR — Act: Edge appliances under active exploitation require an assume-breach posture: sweep authentication logs on the SMA1000 and hunt for lateral movement originating from its internal IP since the disclosure date, even if patching is in progress.
- Leader — Act: Actively exploited max-severity flaws in remote-access appliances are board-question territory — confirm within 24 hours whether SMA1000 is in your estate, ensure emergency patching is authorized, and prepare a brief in case the story escalates.
- Signals: CVE-2026-102255 — CISA KEV: not listed, EPSS 0.00, public PoC on GitHub
- Engineer — Plan: SMA1000 is a perimeter remote-access gateway many enterprises run; apply the released hotfixes promptly and set a watch on CISA KEV — SonicWall edge devices have a strong historical track record of rapid weaponization once a patch ships. No public PoC or active exploitation is reported yet, so this doesn’t cross into Act today.
- SOC/IR — Skip

- Engineer — Learn: No patch or configuration change required; this is a technique highlight showing attackers deploy legitimate RMM clients to blend in. Worth auditing your estate for unauthorized ScreenConnect installations and confirming it appears only where IT-sanctioned.
- SOC/IR — Plan: Build or tune detections for ScreenConnect client processes spawning in unexpected contexts (non-IT endpoints, unusual parent processes, new installs outside change windows); review your SIEM for ScreenConnect relay connections to external infrastructure.
- Leader — Skip
- Engineer — Plan: TeamViewer is widely deployed for remote access in enterprise environments, making it a high-value target; no KEV listing or public PoC is reported, so queue patching of affected client and host software within your normal critical-patch window rather than treating it as an emergency.
- SOC/IR — Skip
- Leader — Skip
- Engineer — Act: A critical ScreenConnect vulnerability is under active exploitation with CISA issuing a warning — patch ConnectWise ScreenConnect to the latest patched version immediately, or isolate/disable instances until patching is complete.
- SOC/IR — Act: Active exploitation of a remote access tool is a priority assume-breach scenario; hunt for anomalous ScreenConnect sessions, unexpected remote access activity, and lateral movement originating from ScreenConnect processes since the disclosure date.
- Leader — Act: Confirm whether ScreenConnect is in use across your environment (including MSP vendors who may use it to manage your systems) and verify emergency patching is underway; active exploitation of remote access tools frequently precedes ransomware deployment.
- Engineer — Act: ScreenConnect is a high-value exploitation target with a documented history of rapid weaponization; apply ConnectWise’s published temporary mitigations now and schedule patch deployment as soon as it releases later this week.
- SOC/IR — Plan: No active exploitation or IOCs yet, but ScreenConnect has been abused repeatedly as an initial-access vector; build or tune detections for anomalous ScreenConnect session activity before exploitation emerges.
- Leader — Plan: Confirm whether ScreenConnect is in your environment, verify mitigations have been applied by your team, and track the patch release this week — ScreenConnect flaws have historically triggered rapid, widespread exploitation that can prompt customer inquiries.
- Engineer — Learn: No CVE or patch involved — attackers are abusing a legitimate admin tool’s functionality. Review whether Faronics Deploy is in your environment and whether its deployment permissions are appropriately scoped.
- SOC/IR — Act: Hunt for unexpected ScreenConnect installations originating from Faronics Deploy processes; build detections for remote-management tool deployments not initiated by IT change management workflows.
