In partnership with
This week emphasizes overlapping stealth risks: CVE-2025-5086 in DELMIA Apriso has been added to the CISA KEV after active exploitation, WhatsApp zero-day spyware is being deployed via zero-click attacks on iOS, and Akira ransomware is leveraging old SonicWall firewall flaws.
In parallel, the UK’s ICO highlights a surge in student-driven insider threats across education. If mobile, ICS, and insider controls aren’t tightened, exposure will spread quickly.
The Business Brief Executives Actually Trust
In a world of sensational headlines and shallow analysis, The Daily Upside stands apart. Founded by former bankers and seasoned journalists, it delivers crisp, actionable insights executives actually use to make smarter decisions.

That’s why over 1 million readers, including C-suite executives and senior decision-makers, start their day with it.
No fluff. No spin. Just business clarity.
Top-level takeaways this week:
Zero-Days & Exploits ↑: Exploitation of CVE-2025-5086 in DELMIA Apriso and SonicWall firewall reuse.
Mobile/Consumer ↑: WhatsApp zero-click spyware pushes risk to personal and BYOD devices.
Insider Threats ↑: Credential misuse in schools/universities highlights overlooked identity risks.
1) DELMIA Apriso exploitation – High
CISA added CVE-2025-5086, a deserialization flaw in DELMIA Apriso (CVSS 9.0), to the KEV catalog after confirmed in-the-wild exploitation. The deadline for federal patching is October 2.
Why this matters: Industrial and supply chain software vulnerabilities create systemic downstream exposure. A single vendor flaw can have a ripple effect across multiple industries.
2) WhatsApp zero-day spyware on iOS – High
A WhatsApp zero-click vulnerability (CVE-2025-55177) has been confirmed as distributing spyware to iOS devices without user interaction. Apple pushed urgent iOS security updates.
Why this matters: Zero-click exploits bypass user awareness completely. Mobile fleets, especially executive devices, are now top-tier espionage targets.
3) Akira ransomware leveraging SonicWall flaws – Medium
Akira ransomware operators are exploiting a year-old SonicWall firewall vulnerability, chaining multiple attack vectors for access.
Why this matters: Old edge vulnerabilities are never truly dead. If your patch cycle missed a round, assume attackers are already testing it.
4) Student-driven insider threats rising in education – Medium
The UK’s ICO reports that over half of insider cyber incidents in schools are now caused by students misusing weak passwords, sharing credentials, or directly exploiting systems.
Why this matters: Insider threats aren’t limited to staff or contractors. Even low-level user groups (students, interns, temps) can become high-impact disruptors.
Stage | Vector | What We’re Seeing |
|---|---|---|
Initial Access | Zero-click & Edge flaws | Exploitation of WhatsApp zero-day and old SonicWall firewalls; DELMIA Apriso deserialization bug. |
Lateral/Persist | ICS & Insider misuse | Weak credential hygiene in education; poorly monitored vendor ICS deployments. |
Impact | Data theft & disruption | Spyware enabling surveillance; ransomware disrupting operations; insider threats eroding trust. |

🔄 Patch & Hardening
Apply vendor fixes for CVE-2025-5086 in DELMIA Apriso immediately.
Push iOS/WhatsApp updates addressing CVE-2025-55177 across all mobile fleets.
Update SonicWall firmware and validate no legacy services are exposed.
🧑💻 People & Monitoring
Hunt for anomalous outbound traffic from mobile devices and ICS servers.
Enforce credential audits in educational and research environments.
Monitor SonicWall logs for repeat exploitation attempts or unusual sessions.
📋 Process
Freeze firewall/edge device changes through Monday except emergency patches.
Update incident response playbooks with zero-click mobile spyware and insider threat triage.
🤝 Partners
Require attestations from vendors/MSPs confirming remediation of DELMIA Apriso and SonicWall flaws.
Coordinate with education sector partners to enforce password resets and MFA where possible.
Zero-days and legacy flaws are converging - new (WhatsApp, Apriso) and old (SonicWall) vulnerabilities are live.
Mobile spyware is stealthy and immediate - executives’ phones are espionage goldmines.
Insider threats are not hypothetical - even students are becoming an active attack surface.
🔄 Attest: All DELMIA Apriso systems are patched against CVE-2025-5086.
📊 Validate: iOS/WhatsApp devices in your fleet have applied fixes for CVE-2025-55177.
💼 Confirm: SonicWall edge devices are current, with legacy exposures disabled.
🔹 Double-check: Monday tabletop: “WhatsApp zero-click spyware → ICS exploitation → insider misuse → exfiltration.”
Final Insight: This week shows attackers don’t need new tricks—they need unpatched software, overlooked mobile fleets, and inattentive insider controls. Don’t let the weekend be their opportunity.
