Wallet Data Leaks 27.09.2026: Self-Custody Security
An explanatory publication for the Baltic and Nordic crypto exchange, hardware wallet, card, and tax tool segment: no new clearly datable events in the last 24 hours or the last week, so we delve into September's supply chain and email service data leaks that expose hardware wallet users to phishing.
No new clearly datable events in our segment in the last 24 hours or the last week, so we offer an explanation. In September, Trezor and BitBox user data came into focus: a ShipMonk supply partner leak (13.08., expanded 04.09. to ~80,000 US customers) and a Brevo email platform breach, which caused a wave of phishing against ~347,000 users between 09.-11.09. Seed phrases and funds were not affected; the human layer of trust was compromised. With practical recommendations for the region's self-custody users and a regulatory watchlist.

Hardware Wallet Security 06.09.2026: The Coldcard Lesson
An explanatory and analytical article on the August Coldcard and BitBox firmware incidents and what a weak randomness flaw means for self-custody in the Baltics and Nordics. Context, not breaking news.
There's no primary, date-specific news in our segment from the last 24 hours, so this is an honestly labelled explanation. We take an in-depth look at the August Coldcard randomness flaw (affecting firmware since March 2021, patched on 20th August) and the BitBox patches from 18th August. The main lesson: updating alone isn't enough - affected seed phrases require complete replacement.

Hardware Wallet Security 21.07.2026: The Laser Test Lesson
An explanatory and analytical article on the physical security of hardware wallets in the context of Baltic and Nordic self-custody – what the Ledger Donjon laser attack on Tangem cards truly means, and how to compare the security architectures of Ledger, Trezor, BitBox, Coldcard, and Tangem.
Over the past 24 hours, there has been no specific primary news in the Baltic and Nordic crypto exchange segment, so this is an honestly labelled explanation, not a news report. We examine an ongoing topic from our hardware wallet category: to what extent physical attacks (e.g., the Ledger Donjon laser test on Tangem cards) threaten self-custody, how to compare the security architectures of Ledger, Trezor, BitBox, Coldcard, and Tangem, and what this risk means for a real user in the region.

Baltics MiCA implementation: Malta vs. Germany model
Germany's approach is too conservative — it kills innovation that is the only competitive advantage we have in the Baltics
Opinion: Germany's BaFin conservative MiCA implementation is stifling fintech innovation. The Baltic states — Latvia, Lithuania and Estonia — should instead follow Malta's MFSA proactive and business-friendly approach to become Europe's next-generation fintech hub.
