😧 In 2025, a hacktivist group filmed itself blocking biomass fuel supply and triggering emergency alarms at a Polish factory, then posted the video on Telegram.

Group-IB's Threat Intelligence team analyzed the 2025–early 2026 threat landscape targeting European manufacturing across six countries.

What we detected ⬇️
▪️200 hacktivist incidents targeting European manufacturers
▪️57 cases of claimed access to industrial control systems

‼️ The shift is real: hacktivist groups have moved beyond website takedowns to physical control of production systems, manipulating boiler temperatures, ventilation pressure, and biomass fuel supply.

Hacktivism is only one of five threat categories covered in our new report, Inside Europe's Manufacturing Cyber Threat Landscape. The other four are just as urgent.

💳 The $48 Billion Blind Spot: Why Merchants Pay for Card Breaches They Can’t See

The scale of the problem:
🔹200M+ compromised payment cards actively circulating in underground markets
🔹E-commerce fraud projected to reach $53 billion in 2025
🔹Every $1 of fraud costs merchants $4.61 once chargebacks, fees, and operational costs are factored in

Why merchants can’t access the intelligence:
1️⃣ PCI DSS prohibits storing raw card data
2️⃣ Card network notification systems (Visa CAMS, Mastercard SAFE) operate issuer-to-issuer only
3️⃣ GDPR and data protection laws block cross-border sharing of personal identifiers

The result: Merchants absorb losses from cards that were already confirmed compromised. They just had no way to know.

What’s changing: Privacy-preserving Distributed Tokenization enables real-time compromised card checks at authorization, without raw card data or PCI DSS scope expansion.
