Weekly Cybersecurity Digest [May, Week 2]
Posted on May 12, 2026
Dear Valued Clients,
Welcome to this week’s cybersecurity digest from Make Sense, your trusted partner in building measurable resilience across Europe’s rapidly evolving digital and financial ecosystems. This week highlights a growing convergence of critical infrastructure exposure, AI-enabled cyber capability, and increasing regulatory pressure across Europe’s digital landscape.
From attacks targeting water treatment systems to exploited enterprise vulnerabilities and growing concern around AI-assisted cyber threats, organisations are being reminded that cyber risk is becoming faster, more interconnected, and increasingly operational in nature. At the same time, European regulators and financial authorities are moving quickly to reassess how resilience should be governed in an era of rapidly evolving AI capabilities.
✅ Top Stories of the Week
i. Polish Intelligence Warns Hackers Targeted Water Treatment Systems
Poland’s domestic intelligence service warned that attackers breached water treatment facilities in five towns, in some cases gaining access to industrial control systems. The incidents created a direct risk to continuity of water supply operations and reflect wider concern over hostile cyber activity targeting European critical infrastructure, especially against the backdrop of Russia-linked sabotage and cyber operations.

ii. Ivanti Mobile Management Zero-Day Exploited in Attacks
Ivanti released fixes for five high-severity vulnerabilities in its Endpoint Manager Mobile product, including one exploited as a zero-day. Previous related Ivanti flaws reportedly affected European entities including the European Commission, the Dutch Data Protection Authority, and Finland’s government ICT service centre. The case reinforces the importance of rapid patching, admin credential rotation, and endpoint management oversight. [Read more via Help Net Security]
iii. German Authorities Shut Down Relaunched Criminal Marketplace
German authorities shut down a relaunched version of the Crimenetwork marketplace and arrested its suspected operator in Mallorca under a European Arrest Warrant. The platform allegedly had more than 22,000 users and over 100 vendors, offering stolen data, forged documents, drugs, and illegal services. The case shows how quickly cybercriminal ecosystems can rebuild after enforcement action. [Read more via Help Net Security]
✅ Industry Trends & Insights
Google Warns Hackers Are Innovating With AI-Enabled Attacks
Google said a cybercrime group used AI to discover a previously unknown software flaw and build an exploit attempt, marking a significant shift in attacker capability. While the attack was blocked before mass exploitation, the finding shows how AI could reduce the time and expertise needed to launch complex campaigns, including against European organisations and financial systems.

Linux Kernel Flaws Signal a Looming Patch Pressure Problem
A second major Linux kernel flaw, “Dirty Frag,” followed the earlier “Copy Fail” disclosure, with major distributions including Ubuntu, SUSE, Debian, Fedora, and Red Hat moving on patches or mitigations. The issue highlights a broader problem: AI-assisted vulnerability discovery may compress years of hidden technical debt into urgent patch waves for already-stretched security teams.

ECB Studies Defences Against AI-Powered Cyber Threats
The European Central Bank confirmed it is studying defences against cyberattacks potentially accelerated by Anthropic’s advanced AI model “Mythos”. Officials warned that frontier AI systems capable of identifying software vulnerabilities could increase risks to banking systems and critical financial infrastructure. The ECB is now assessing how prepared banks are for increasingly sophisticated AI-enabled cyber threats. [Read more via Reuters]
✅ Regulatory & Policy Updates
EU Reaches Provisional Deal to Weaken and Delay Parts of the AI Act
EU lawmakers and member states reached a provisional agreement to dilute and delay parts of the bloc’s landmark AI Act, postponing key obligations for high-risk AI systems until late 2027. Supporters say the changes reduce compliance burdens for businesses, while critics warn the softer approach could weaken safeguards around high-risk technologies. The debate reflects Europe’s ongoing struggle to balance innovation, competitiveness, and digital risk governance. [Read more via Reuters]
EU Reviews Access to Cybersecurity-Capable AI Models
The European Commission said OpenAI offered access to its cybersecurity features, while Anthropic had not yet made a similar offer around its models. The discussion shows how regulators are moving beyond abstract AI policy and into practical questions: who gets access to powerful cyber-capable models, under what controls, and how they can support trusted defensive use. [Read more via Reuters]
Germany’s BaFin Steps Up Cyber Inspections Over AI Risks
Germany’s financial regulator BaFin warned that AI is making cyber risks “growing” and “substantial,” especially as models become faster at identifying and exploiting vulnerabilities. BaFin announced a new division for targeted “IT spotlight” inspections of financial firms, signalling that regulators expect banks and financial institutions to treat AI-driven cyber risk as an urgent resilience issue.

✅ Cyber IQ Challenge + Proactive Security Hacks
Quick Quiz:
Which of the following is considered one of the biggest cybersecurity concerns linked to advanced AI systems?
A) Slower software updates
B) Increased electricity consumption
C) Faster identification and exploitation of vulnerabilities
D) Reduced internet connectivity
(Answer below)
Smart Security Moves of the Week:
- Critical infrastructure review: Assess whether operational systems are properly segmented and monitored.
- Patch discipline: Prioritise exploited vulnerabilities and rotate privileged credentials after exposure.
- AI governance: Map where AI could strengthen defence — and where it could accelerate attacks.
- Regulatory tracking: Monitor EU AI Act changes and their impact on high-risk systems.
Answer: C) Faster identification and exploitation of vulnerabilities
Because advanced AI systems can help attackers discover weaknesses faster, compressing the time organisations have to patch, respond, and contain risk.
✅ Conclusion
This week’s developments reinforce a major shift in Europe’s cybersecurity landscape: the challenge is no longer only about preventing breaches — it is about maintaining resilience against faster, more adaptive, and increasingly AI-assisted threats.
Whether through attacks on critical infrastructure, exploited enterprise platforms, or concerns around frontier AI systems accelerating vulnerability discovery, organisations are facing growing pressure to strengthen visibility, governance, and operational readiness across interconnected environments.
Final reflection: If a critical vulnerability or AI-assisted attack emerged inside your organisation tomorrow, how quickly could your teams detect, prioritise, and contain the impact before operations were disrupted?
At Make Sense, we help organisations transform emerging cyber risks into measurable resilience — strengthening governance, securing critical systems, and preparing for Europe’s rapidly evolving cybersecurity and regulatory landscape.
