Ledger Security Breach Exposes $90M in Crypto Theft as Hardware Vulnerabilities Surface On October 18, 2026, cryptocurrency hardware wallet manufacturer Ledger disclosed a major security incident involving malicious modifications to its devices, potentially leading to the theft of over $90 million in crypto assets. The breach, initially traced to the Malaysian retailer CryptoBilis, has since expanded to other sales channels, suggesting a global supply chain compromise that may affect numerous customers. The incident underscores critical vulnerabilities in cryptocurrency hardware security, where tampered devices could expose user data and funds. Investigations are ongoing, with Ledger working to identify the full scope of the affected devices and distribution networks. Super Micro Computer Inc. (SMCI) Faces Market Scrutiny Amid Broader Tech Sector Pressures While unrelated to the Ledger breach, Super Micro Computer Inc. (SMCI), a key player in high-performance server and storage solutions, is under financial scrutiny. The company, with a $20.78 billion market capitalization, serves data centers, cloud providers, and enterprises but currently operates at a cash-flow-negative status. SMCI’s Price-to-Sales (P/S) ratio of 0.56 well below its historical median reflects market skepticism about its growth prospects, as traditional valuation metrics like P/E are inapplicable due to its financial position. Despite this, its GF Score™ of 85/100 highlights strong growth potential (ranked 10/10) and profitability (8/10), though its valuation rank of 2/10 suggests investor caution. Insider Activity Raises Concerns Over the last three months, SMCI insiders have sold $24.44 million in shares, signaling potential unease among executives. Meanwhile, eight institutional investors (gurus) hold positions, with seven increasing their stakes in recent quarters indicating mixed but cautiously optimistic sentiment. The Ledger breach and SMCI’s financial challenges reflect broader risks in the tech and crypto sectors, where security lapses and market volatility continue to shape industry dynamics.
