Weekly Cybersecurity Digest [June, Week 4]
Posted on June 30, 2026
Dear Valued Clients,
Welcome to this week’s cybersecurity digest from Make Sense. This week highlights how Europe’s cyber risk is increasingly shaped by criminal infrastructure, public-sector exposure, ransomware pressure, and hostile-state activity.
From Operation Endgame’s disruption of malware infrastructure to cyberattacks affecting public institutions and messaging accounts, the message is clear: attackers are exploiting the systems that enable trust, access, and operational continuity. At the same time, Europe is strengthening law enforcement capability and pushing organisations, especially SMEs, toward more practical cyber resilience under the Cyber Resilience Act.
✅ Top Stories of the Week
i. Operation Endgame Disrupts Amadey And StealC Malware Infrastructure
Europol, Eurojust, Microsoft, and international partners disrupted infrastructure linked to the Amadey and StealC malware operations under Operation Endgame. Authorities targeted servers, domains, and criminal assets used to steal credentials, support initial access, and enable ransomware and fraud activity. The action matters because modern cybercrime is increasingly infrastructure-driven: malware families, stolen credentials, and access brokers form the supply chain behind many enterprise attacks.

ii. France’s Statistics Department Reports Cyberattack On Staff Data
France’s national statistics department, Insee, reported a cyberattack affecting personal data from its internal directory. Around 12,800 current and former staff and members of related civil service bodies were affected, with identities and professional contact details exposed. Insee said no passwords, bank data, social security numbers, health information, or personal contact details were accessed. The incident reinforces how even limited public-sector data exposure can create trust, phishing, and institutional risk. [Read more via Reuters]
iii. Russia-Linked Social Engineering Campaign Targets Messaging Accounts
Ukraine’s security agency said it uncovered, together with the FBI, a long-running Russian campaign to compromise messaging accounts used by government officials, military personnel, politicians, and activists in Ukraine, Europe, and the United States. Rather than exploiting the messaging platforms directly, attackers relied on social engineering to steal credentials and verification codes. The case highlights a familiar but critical weakness: trusted communication channels remain vulnerable when human trust is manipulated. [Read more via The Record]
✅ Industry Trends & Insights
Ransomware Attacks Against Europe Rise Sharply
A new Black Kite report found a major rise in ransomware attacks targeting European organisations, with manufacturing heavily affected and Germany, the UK, France, Italy, and Spain among the most exposed markets. This is a strong Industry Trends & Insights item because it identifies a broader pattern rather than a single incident: ransomware pressure across Europe is intensifying, especially where industrial operations, supply chains, and regional economic concentration create high-value targets.

Russian Espionage Tooling Shows Long-Term Investment In European Access
Google Threat Intelligence reported that Turla, a Russia-linked espionage group, has continued developing and deploying the STOCKSTAY backdoor against Ukrainian government and military organisations, with earlier samples also seen in Italy, the Netherlands, Poland, and Germany. The campaign shows how state-backed actors maintain long-term malware ecosystems to preserve access even when individual tools are detected. For European organisations, persistence and stealth remain central espionage risks. [Read more via The Record]
✅ Regulatory & Policy Updates
EU Moves To Strengthen Europol Against Digital And Cross-Border Crime
The European Commission proposed measures to strengthen Europol’s ability to respond to rising digital and cross-border crime. The plan includes stronger cooperation tools, a sovereign cloud infrastructure, shared data capabilities, and expanded support for national investigations. The move reflects a wider European policy direction: law enforcement needs faster, more interoperable systems to respond to cyber-enabled crime that moves across borders, platforms, and jurisdictions.

SMEs Need Practical CRA Readiness Support, ENISA Finds
ENISA published its SME Cyber Resilience Act survey report, showing that smaller organisations need clearer guidance and practical tools to understand and implement CRA obligations. The report found that while many SMEs are aware of the regulation, uncertainty remains around scope, product-security requirements, and supply-chain responsibilities. For European businesses, CRA readiness is becoming less about legal awareness and more about practical product-security governance. [Read more via ENISA]
✅ Cyber IQ Challenge + Proactive Security Hacks
Quick Quiz: Which cybersecurity practice gives organisations the strongest foundation for managing modern digital risk?
A) Buying more security tools without changing governance
B) Treating cybersecurity as a purely technical function
C) Mapping critical assets, dependencies, identities, suppliers, and response responsibilities
D) Waiting until an incident happens before testing recovery plans
(Answer below)
Smart Security Moves of the Week:
- Credential exposure review: Monitor for stolen credentials, enforce phishing-resistant MFA, and review privileged account activity.
- Public-sector data awareness: Treat professional contact data as useful intelligence for phishing, impersonation, and social engineering campaigns.
- Communication-channel security: Train high-risk users to verify account-support messages, login prompts, and unexpected verification requests.
- Legacy infrastructure planning: Identify ageing digital systems supporting critical operations and include them in continuity and replacement planning.
Answer: C) Mapping critical assets, dependencies, identities, suppliers, and response responsibilities.
Cyber resilience starts with knowing what matters, who depends on it, how it is protected, and who must act when something fails or is compromised.
✅ Conclusion
This week reinforces a practical reality for European organisations: cyber resilience depends on understanding the infrastructure behind the threat. Malware networks, stolen credentials, ransomware ecosystems, public-sector data exposure, and espionage tooling all show how cyber risk can scale quickly once trust and access are compromised.
Europe’s response is becoming more coordinated — from disrupting criminal platforms to strengthening Europol and supporting CRA readiness. For organisations, the priority is to improve visibility, secure dependencies, and turn regulatory expectations into workable operational controls.
Final reflection: If attackers targeted your organisation through stolen credentials, a trusted communication channel, public data exposure, or a supplier weakness, would leadership understand the impact quickly enough to act?
At Make Sense, we help organisations turn cyber complexity into practical resilience across Europe’s evolving threat landscape.
