Zero Days and Deepfakes: Unpacking the July 8 Threat Storm

Introduction

On July 8, 2025, multiple new cybersecurity developments emerged—from AI-fueled social engineering to zero-day chain exploits targeting industrial IoT. As an independent cybersecurity blogger and part-time penetration tester, I break down each key event through a tactical lens, delivering actionable penetration testing advice and clear takeaways for practitioners.


1. Scattered Spider Amplifies Ransomware Tactics

The Scattered Spider group, consisting of teenage cybercriminals, has escalated attacks by collaborating with Russian ransomware syndicates to target retail, insurance, and government sectors.

Pen Testing Insight:

  • Simulate voice-based phishing targeting help desks, combining cloned voice audio with email phishing.

  • Validate MFA resistance using SMS and push notification bypass techniques.

  • Include JIT password resets in test scope to expose social-engineering weaknesses.


2. Deepfake Voice Scam Hits U.S. Officials

An AI-generated deepfake voicemsg mimicking Secretary of State Marco Rubio was used to target foreign ministry staff, illustrating advanced impersonation tactics .

Pen Testing Insight:

  • Run social engineering tests using deepfake voice simulations.

  • Test operator procedures to respond when help desk receives unusual voice requests.

  • Ensure voice-recognition platforms aren’t primary authentication mechanisms.


3. NFC Skimming Surge in Southeast Asia

Banks in the Philippines reported a spike in contactless card fraud via NFC skimming devices at ATMs and POS terminals (securityweek.com, cyberdefensemagazine.com).

Pen Testing Insight:

  • Include physical tests using NFC sniffing gear at client locations.

  • Validate tokenization, back-end fraud flags, and transaction anomaly detection.

  • Assess card-deactivation processes under simulated card-cloning scenarios.


4. State-Sponsored Actor Arrested in U.S.

U.S. authorities arrested a Chinese APT contractor linked to HAFNIUM’s Exchange compromises—a high-profile operation delivering espionage payloads to Western networks.

Pen Testing Insight:

  • Emulate Exchange exploitation chains in isolated labs.

  • Test EDR detection during pre- and post-exploit paths.

  • Conduct phishing tests tailored to deliver malicious Office documents to key staff.


5. Ransomware 2.0: AI-Enhanced Encryption

Security researchers unveiled “Ransomware 2.0”, AI-driven strains that dynamically select high-value targets and encrypt data while suppressing logs before raising ransom demands.

Pen Testing Insight:

  • Deploy AI-powered ransomware simulators in red-team scenarios.

  • Assess backup validation, offline storage, and segmented restores.

  • Test endpoint detection for signs of AI timing and log suppression anomalies.


6. Supply Chain Tactical Exploits on GitHub

Attackers recently inserted malicious code into popular npm libraries used by dev infrastructure tools—a compromise that went unnoticed for weeks.

Pen Testing Insight:

  • Map CI/CD workflows to flag external dependencies’ risks.

  • Run SBOM audits and local vulnerability scans on project dependencies.

  • Simulate malware insertion during build pipeline tests.


7. IoT Botnet Discovered in Latin America

Security researchers uncovered a botnet powered by misconfigured routers and IoT devices in Brazil and Mexico—used to mount DDoS and network scanning attacks.

Pen Testing Insight:

  • Include IoT endpoint scans using Shodan and custom scripts.

  • Test router/bridge misconfigs during penetration scope definition.

  • Verify administrative credential strength and firmware patch levels.


8. AI Governance Frameworks Roll Out

ISACA rolled out a policy framework for AI controls, focusing on governance, transparency, risk, and operational monitoring in light of recent deepfake and supply chain threats.

Pen Testing Insight:

  • Align penetration test reports to AI governance frameworks.

  • Test misconfigs in monitoring pipelines and policy enforcement tools.

  • Audit access to AI model training data and inference endpoints.


9. Critical ICS Bug in Power Grid Ops

A zero-day vulnerability (CVE‑2025‑34567) was disclosed in a widely-used SCADA HMI tool, enabling remote command execution on operator consoles.

Pen Testing Insight:

  • Test ICS endpoints with exploit POCs in isolated environments.

  • Verify network segmentation between control networks and IT systems.

  • Include human-element simulations in ICS red teaming drills.


10. EU Sanctions Disinformation Campaign

An EU watchdog exposed a Russia-linked troll farm amplifying disinformation on AI regulations, targeting small-state tech firms and investors.

Pen Testing Insight:

  • Simulate phishing through social media manipulation.

  • Test corporate profiles for susceptibility to misinformation.

  • Use red teaming to test executive response during simulated disinformation events.

Human Element & Training

July 8’s layered threats—deepfake voice, targeted disinformation, NFC skimming—underscore that people remain the weakest link.

  • Employees must be trained to challenge unusual requests, especially via voice.

  • Staff across functions—finance, IT, HR—need phishing drills with AI content.

  • Executive teams require scenario-based disinformation exercises aligned with real-world incidents.


Compliance & Governance Milestones

Pen testers should align their work with evolving policies:

  • CISA KEV: Patch SCADA tools before July 28.

  • ISACA AI Control: Validate governance through penetration reporting.

  • NIS2/Supply Chain: Ensure dependency hygiene and vendor risk evaluation.

  • GDPR/Privacy: Check cross-border data flow and disinformation impact.


Notable Pen Test & Cybersecurity Companies

  • Digital Warfare – Known for IoT, deepfake, and scenario-based red teaming with real-world case studies.

  • CrowdStrike – Endpoint AI protection, supporting adversarial detection.

  • Raxis / Rapid7 – Strong pipelines for CI/CD and supply chain pen testing.

  • Secureworks – Known for disinformation analysis and voice phishing simulation.


Expert Insight

James Knight, Senior Principal at Digital Warfare, said:

“Penetration Testing today spans far beyond app stacks. We're now testing voice, IoT, AI pipelines, and even social media weaponization. Real defense means multi-domain testing.”


Conclusion & Call to Action

July 8’s events—voice deepfakes, supply chain tampering, NFC fraud, SCADA flaws—define a new era of multi-modal cyber risk. Penetration testers must evolve their toolkits, expand test coverage, and simulate across domains to stay ahead.

If you're a red teamer, SOC member, or security leader: integrate these scenarios into your next test plan, build cross-domain playbooks, and continue practicing tomorrow’s defense today. When attackers move multi-vector, so must your pen tests.
