- Engineer — Skip
- SOC/IR — Learn: Actor profile worth logging: FulcrumSec targets travel/transport sector and appears to exfiltrate before disclosure; no IOCs or TTPs published to act on yet.
- Leader — Act: If your organisation uses MAG airports or shares traveller data with them, request a formal incident report and assess whether your customers’ data is in scope for notification obligations.
- Engineer — Learn: No attack vector or affected software identified in this report, so there is nothing to patch or reconfigure yet; monitor for technical disclosure about how Qilin gained access.
- SOC/IR — Plan: Qilin ransomware is confirmed active against US federal targets; no IOCs or TTPs are published yet — queue a detection-readiness review for Qilin TTPs (double extortion, ESXi targeting) and set a watch for any forthcoming IOC releases from this incident.
- Leader — Plan: A confirmed ransomware compromise of a US federal law-enforcement agency is board-visibility material, particularly for defense contractors or regulated entities with ATF data-sharing relationships — schedule a leadership brief on ransomware posture and verify whether your org has any data exposure through ATF systems.
- Engineer — Skip
- SOC/IR — Learn: Awareness of this double-extortion tactic helps analysts brief IR teams and counsel victims to verify recovery vendor legitimacy before engaging; no IOCs or detection surface provided.
- Leader — Plan: If your org ever faces ransomware, pre-vet legitimate recovery firms now and add vendor verification steps to your IR playbook to avoid paying fraudulent intermediaries.
- Engineer — Learn: No technical vulnerability or patch action here, but engineers involved in ransomware IR should know secondary extortion schemes like this exist and treat unsolicited ‘data deletion’ offers as suspect.
- SOC/IR — Learn: No IOCs or detectable TTPs are provided, but IR analysts should add this pattern to their ransomware playbooks — unsolicited emails from third parties claiming server access during an active incident are a red flag to escalate, not engage.
- Leader — Learn: If the organization is ever a ransomware victim, communications teams should know that secondary fee-based offers to delete stolen data are likely scams; worth a brief mention in IR tabletop exercises and vendor-communications guidance.
- Engineer — Learn: The CISA/FBI advisory likely details initial-access vectors (historically RDP abuse and phishing) worth reviewing to validate existing hardening; no specific exploited CVE is surfaced in this summary, so no emergency patch action required.
- SOC/IR — Act: Pull the full CISA advisory for Medusa IOCs and ATT&CK TTPs, then hunt for those indicators in endpoint and network telemetry dating back to mid-2021 if within retention; tune ransomware-staging detections against the published behaviors.
- Leader — Act: A named campaign with 500+ confirmed critical-infrastructure victims backed by a joint CISA/FBI advisory is likely to generate board and customer questions this week; brief leadership on your sector’s exposure and confirm your ransomware IR plan and backup posture are current.
- Engineer — Act: CISA-confirmed active exploitation by ransomware operators means patch immediately — apply the Microsoft Windows Task Host security update to all Windows endpoints and servers; prioritize internet-facing and domain-joined systems.

- Leader — Act: If Shell is a vendor or partner, request their incident status and any attestation of scope this week; even without confirmed breach, brief leadership before this surfaces in board or customer questions.
- Engineer — Plan: Verify your EDR agent is configured to load and protect in Safe Mode, and audit whether bcdedit or safeboot registry keys can be modified by non-admin processes — most EDR platforms have a specific setting for this that is not always on by default.
- SOC/IR — Act: Hunt for bcdedit commands setting safeboot (T1562.001) and unexpected Safe Mode reboots in Windows event logs since Akira affiliates actively use this to blind EDR before data theft; tune alerts on bcdedit execution from unexpected parent processes.
- Leader — Learn: Akira affiliates are successfully exfiltrating data even when encryption fails, confirming that ransomware incidents now carry extortion risk independent of operational disruption — worth a note in the next risk-register review.
- Engineer — Skip
- SOC/IR — Learn: ExfilSquad is an active extortion actor worth tracking; no IOCs or TTPs are publicly available yet to act on, but monitor for follow-on disclosures with actionable detection detail.
- Leader — Act: If Wesco is a vendor or supplier in your ecosystem, contact them now for an incident scope statement and assess whether shared data or integrations are at risk; brief leadership before this surfaces in broader news.
- Engineer — Learn: No patch or config action required, but this technique — using decentralized blockchain services instead of traditional C2 — changes how defenders should think about network egress controls and ransomware resilience. Review whether your environment restricts outbound connections to blockchain RPCs and the Session messaging network.
- SOC/IR — Plan: DeadLock’s use of Polygon smart contracts and Session protocol for victim comms creates a new detection surface; build or tune detections for Session network traffic and Polygon RPC calls originating from endpoints and servers, and add this TTP to ransomware hunt playbooks this quarter.
- Leader — Learn: Ransomware groups adopting decentralized infrastructure reduces the effectiveness of traditional law-enforcement takedowns, which has implications for incident response assumptions and cyber-insurance negotiations around extortion scenarios — useful context for the next IR retainer or insurance renewal discussion.
- Engineer — Learn: No patch or configuration action available; the technique signals that traditional domain-takedown mitigations matter less for this operator, which is worth factoring into egress-filtering and backup-isolation architecture reviews.
- SOC/IR — Learn: No IOCs or ATT&CK-mapped TTPs are available to hunt or detect; worth absorbing for IR playbook updates, as blockchain-backed C2 limits the value of expecting law-enforcement takedown to cut off active intrusions.
- Leader — Learn: Useful framing for board-level ransomware risk discussions: blockchain-anchored infrastructure reduces the effectiveness of law-enforcement disruption as a risk mitigant, which may affect how resilient response plans need to be.
- Engineer — Plan: A joint government advisory signals active ransomware targeting critical infrastructure; review backup integrity, network segmentation, and endpoint hardening against ransomware TTPs this quarter.
- SOC/IR — Act: Joint advisory from US agencies and South Korea’s NPA indicates active Gunra ransomware campaign — hunt for associated TTPs and IOCs once the full advisory is reviewed, and ensure ransomware-stage detections (lateral movement, mass encryption) are tuned.
- Leader — Plan: A US government warning about ransomware targeting critical infrastructure warrants briefing leadership and confirming your sector’s exposure; add Gunra to the risk register and verify incident response plans cover ransomware scenarios.
- Engineer — Learn: A new ransomware strain from a Medusa affiliate signals an active threat actor pivoting to new tooling, but the thin summary provides no specific vulnerability, attack vector, or affected software to patch or harden against today.
- SOC/IR — Learn: Tracking a Medusa-lineage actor rebranding to StormEncryptor is useful triage context, but no IOCs, TTPs, or ATT&CK mappings are provided — file for actor awareness until a fuller technical report with detection surface emerges.
- Leader — Skip
- Engineer — Plan: If your environment includes N-able N-central (common in MSP-managed or hybrid estates), apply any available patches and audit for signs of unauthorized remote execution; the vector is described as likely rather than confirmed, so no KEV urgency, but RMM tools are high-value pivot points.
- SOC/IR — Plan: Storm-1175 has shifted tooling from Medusa to a new C++ ransomware appending .encrypted; build or tune endpoint detections for that extension and ransomware-stage behaviors, and track this actor’s TTPs as Microsoft Threat Intelligence is actively reporting on the campaign.
- Leader — Plan: Confirm whether internal teams or managed service providers in your supply chain run N-central, and if so request a security posture attestation; a financially motivated China-linked actor deploying ransomware via RMM tooling is a credible MSP supply-chain risk worth queuing for this quarter’s vendor-risk review.
- Engineer — Act: Fortinet and Schneider Electric products are named as actively exploited entry points in a joint US/South Korea advisory; audit Fortinet appliances and OT-facing Schneider devices for unpatched vulnerabilities and apply vendor patches immediately.
- SOC/IR — Act: Joint government advisory signals published TTPs and IOCs are available; run a Gunra hunt across network and endpoint telemetry now, prioritizing environments in healthcare, financial services, or government sectors given the stated targeting pattern.

- Leader — Learn: Demonstrates continued commoditization of ransomware operations, useful for board-level narrative on ransomware risk trends, but no sector-specific targeting or vendor exposure is identified that would require immediate leadership action.
- Engineer — Act: Active Cl0p data-extortion campaign exploiting internet-exposed PTC Windchill and FlexPLM via chained pre-auth flaws; immediately audit for internet-exposed instances, apply available patches, and if patching is delayed, restrict Windchill login servlet and FlexPLM WSDL endpoint from external access.
- SOC/IR — Act: Active Cl0p campaign with a concrete exploit chain (pre-auth FlexPLM WSDL disclosure chained into Windchill login servlet); hunt for anomalous pre-authenticated requests to these endpoints since campaign start and sweep for Cl0p-associated IOCs in PLM server logs and EDR telemetry.
- Leader — Plan: Cl0p affiliates are running a targeted data-extortion campaign against manufacturing and engineering organizations using PTC Windchill/FlexPLM; if your org or key suppliers use these platforms, assess exposure now and be prepared to brief leadership on potential data theft risk before it surfaces in the press.
- Engineer — Learn: No patchable vulnerability here — this is a C2 evasion technique that bypasses outbound network controls by abusing the local browser. Worth understanding when designing network egress policy and process-spawn allow-lists, but no immediate system change required.
- SOC/IR — Act: Cisco Talos documented a pre-ransomware implant with a distinctive behavioral fingerprint: it binds only to 127.0.0.1 and spawns Chrome or Edge headlessly to carry C2 traffic — invisible to traditional network detection. Hunt for unexpected headless browser processes with anomalous parent processes and tune EDR rules to flag this spawn chain on Windows endpoints.
- Leader — Learn: Chaos ransomware has deployed a novel evasion capability that makes their pre-encryption activity harder to detect; worth flagging to the security team to ensure detection coverage, but no executive action or vendor exposure check required at this stage.
- Engineer — Learn: The entry point was a data exchange platform shared with a supplier, reinforcing that third-party integrations need isolation and least-privilege access. No specific CVE or software named, so no patch action available.
- SOC/IR — Learn: Confirms Everest ransomware gang is active and targeting supplier-connected platforms, but no IOCs or TTPs are published here to hunt on. File for actor-tracking context.
- Leader — Learn: Illustrates how a shared supplier portal becomes a ransomware entry point — a useful data point for third-party risk reviews and board-level ransomware briefings. No direct vendor relationship requiring immediate action for most organizations.
- Engineer — Learn: Novel C2 technique using legitimate browser processes to blend malicious traffic — no KEV, PoC, or EPSS data means no patch action today, but informs browser isolation and process-spawn monitoring design decisions.
- SOC/IR — Plan: Build or tune detections for unusual network egress spawned from Chrome/Edge processes outside of normal user activity; no IOCs are published in this item yet, but the Chaos gang’s adoption of browser-proxied C2 warrants a detection gap assessment this quarter.

- Engineer — Act: CVE-2026-0257 is CISA KEV-listed with EPSS 0.87 and a public PoC; Qilin actors are actively using it as initial access via PAN-OS portal and gateway. Patch PAN-OS to the fixed release immediately and audit gateway/portal access logs for unauthorized sessions since June 2026.
- SOC/IR — Act: Qilin (Agenda) ransomware operators are actively exploiting PAN-OS edge devices as a beachhead — assume-breach sweep is warranted on any PAN-OS-fronted environment. Hunt for Qilin TTPs and lateral movement artifacts dating back to June 2026, and tune EDR/SIEM detections for Agenda ransomware staging behavior.
- Leader — Act: Qilin ransomware is actively deploying via a widely-used firewall/VPN product; this is board-question-level exposure if your organization runs PAN-OS. Confirm patch status with your engineering team this week and prepare a brief for leadership on whether any environment may have been affected during the June 2026 exploitation window.
- Signals: CVE-2026-0257 — CISA KEV: listed, EPSS 0.87, public PoC on GitHub
- Engineer — Skip
- SOC/IR — Learn: Anubis ransomware group is expanding its public extortion activity against recognizable brands; no IOCs or TTPs released yet, so track the actor for future intel but no hunt work is actionable now.
- Leader — Learn: A named ransomware attack on a major consumer brand with threatened data publication is useful context for board conversations about ransomware risk, but no same-week action is warranted unless your organization has a direct vendor relationship with Fairlife.
- Engineer — Act: A critical authentication bypass in PAN-OS GlobalProtect is being actively weaponized for ransomware intrusions — patch PAN-OS to the fixed version listed in Palo Alto’s advisory immediately, and audit VPN authentication logs for anomalous sessions preceding lateral movement.
- SOC/IR — Act: Qilin’s use of a VPN auth bypass as initial access means compromise may precede any patch; if GlobalProtect is in your environment, run an assume-breach hunt now — look for anomalous GlobalProtect auth events, unusual post-VPN lateral movement, and Qilin-associated TTPs documented in Arctic Wolf’s reporting.
- Leader — Act: Active ransomware exploitation of a widely-deployed VPN product is a board-question-level event — confirm this week whether GlobalProtect is in your estate, verify emergency patching is underway, and prepare a short leadership brief in case an incident surfaces.
- Engineer — Plan: If you run Langflow, vector databases, or store model checkpoints and training datasets, audit whether those assets are covered by offline/immutable backups and restrict write access to AI model storage paths — ransomware operators are now specifically targeting these artifacts.
- SOC/IR — Learn: EncForge represents a new ransomware class deliberately targeting AI infrastructure assets; no IOCs or ATT&CK mappings are available yet, so file this as context for future detections around ML pipeline directories and vector DB processes.
- Leader — Plan: AI training datasets and model checkpoints are now explicit ransomware targets — verify that backup and recovery programs extend to these assets, and add AI model data to the next ransomware tabletop scope if not already present.
- Engineer — Act: Active exploitation of a Langflow RCE is being used to deploy Go-based ransomware that encrypts model weights, vector indexes, and training data. If you run Langflow, patch or network-isolate it immediately and review Sysdig’s full JADEPUFFER report for host-level IOCs to audit your AI infrastructure.
- SOC/IR — Act: A named operator (JADEPUFFER) has been caught in a second confirmed intrusion deploying ENCFORGE ransomware via Langflow; pull Sysdig’s IOC set and hunt for anomalous Go process execution or bulk file encryption activity on hosts running Langflow or adjacent AI pipeline components.
- Leader — Learn: ENCFORGE is the first documented ransomware purpose-built to destroy AI model assets rather than generic data, signaling that AI infrastructure is becoming a distinct extortion target worth adding to the risk register ahead of broader AI investment discussions.
- Engineer — Skip
- SOC/IR — Learn: The sentencing outcome underscores Scattered Spider’s real-world impact — 148 systems downed and 27,000 forced through manual password resets. Useful context for briefings on social-engineering-led intrusions, but no new IOCs or TTPs requiring immediate detection work.
- Leader — Learn: High-profile conviction in a major ransomware attack on critical transit infrastructure; useful framing for board-level discussions on cyber risk consequences and the human cost of social-engineering attacks, but no immediate action required.
- Engineer — Skip
- SOC/IR — Skip
- Leader — Plan: A publicly disclosed ransomware event at a major consumer brand that halted physical production signals continued ransomware targeting of OT environments — worth including in next board or leadership briefing on OT/supply-chain ransomware risk; assess whether Fairlife or Coca-Cola appears in your supplier or vendor list and request status if so.
- Engineer — Skip
- SOC/IR — Learn: Background context on REvil prosecution efforts; no IOCs, TTPs, or detection actions arise from this legal/identity dispute.
- Leader — Learn: Illustrates ongoing U.S. pursuit of ransomware actors via allied extradition — useful context for board-level ransomware risk narratives, but no immediate action required.
- Engineer — Learn: No CVEs, initial-access vector, or specific software named in this report, so there is nothing to patch or reconfigure today; the sub-24-hour timeline reinforces the case for immutable backups and network segmentation as design principles.
- SOC/IR — Learn: The speed metric (initial access to encryption in under 24 hours) is useful context for calibrating containment urgency, but no IOCs, TTPs, or ATT&CK mappings are provided, so no detection or hunt work is actionable from this item alone.
- Leader — Learn: The Spirals timeline is a concrete data point about ransomware dwell-time compression, useful when making the case for detection-and-response investment, but no sector targeting or named-victim context elevates this to an immediate risk-register or board-communication event.
- Engineer — Skip
- SOC/IR — Learn: Law enforcement action against ransomware-enabling infrastructure is worth tracking for actor context, but no IOCs or TTPs are published here that support immediate detection work.
- Leader — Learn: The indictment signals continued US pressure on ransomware infrastructure and is useful context for board-level threat landscape briefings, but requires no immediate organizational action.
- Engineer — Skip
- SOC/IR — Learn: Provides ecosystem context on ransomware infrastructure enablers, but the summary contains no IOCs, TTPs, or detection angles to act on.
- Leader — Act: OFAC designations create immediate sanctions-compliance exposure — confirm whether your organization or any portfolio vendor uses the named VPN service or cryptor, and document the review in case of audit or customer inquiry.
- Engineer — Skip
- SOC/IR — Learn: Useful threat intel context on ransomware-enabling infrastructure being dismantled, but no IOCs, TTPs, or detection surface provided — no immediate hunt or rule work to action.
- Leader — Learn: OFAC action signals expanding regulatory pressure on ransomware enablers; no immediate exposure for legitimate enterprises, but worth noting as evidence the sanctions toolkit is being applied to cybercriminal infrastructure.
- Engineer — Skip
- SOC/IR — Learn: Regional incident with no published IOCs, TTPs, or affected software specifics — useful context for sector awareness but no actionable detection work available.
- Leader — Learn: Transportation sector disruption demonstrates operational risk from cyberattacks on dispatch/logistics systems; useful framing for board conversations about OT/business continuity risk, though no vendor exposure or regulatory action is indicated.
- Engineer — Learn: Emerging affiliate-model ransomware group worth tracking for context, but the summary provides no specific vulnerabilities, affected software, or configuration actions to take today.
- SOC/IR — Learn: New ransomware actor profile worth adding to analyst awareness, but no IOCs, TTPs, or ATT&CK mappings are surfaced in this summary — check the full Unit 42 report for any huntable indicators before queuing detection work.
- Leader — Learn: Affiliate-model ransomware groups expand attack surface broadly; file as emerging threat context for future risk register review, but the thin summary offers no sector-specific targeting data warranting immediate leadership action.
- Engineer — Skip
- SOC/IR — Learn: A Ryuk operator’s prosecution provides retrospective context on the group’s operations, but no new IOCs or TTPs are disclosed, so no detection or hunt work is actionable here.
- Leader — Learn: A guilty plea in a major ransomware case is useful context for board discussions on ransomware risk and law enforcement deterrence, but requires no immediate organizational action.
- Engineer — Skip
- SOC/IR — Learn: Insider-threat angle is notable: attacker was a trusted IR professional with access to victim environments, illustrating how responders can become adversaries — relevant context for vetting IR vendors and monitoring privileged access during incidents.
- Leader — Learn: The case highlights vendor-risk and insider-threat exposure when engaging external IR firms — useful framing for board discussions on third-party access controls and contractual accountability during incident response engagements.
