Ledger SAS has appointed Oded Blatman as chief information officer and chief security officer, combining technology and security oversight in a single leadership role as AI-driven threats expand across the crypto industry. The Paris-based hardware wallet maker said Blatman will oversee cyber and infrastructure security, product security, physical and workplace security, internal IT, and enterprise risk.
One Role for Security and Technology
Blatman joins Ledger after five years as CIO and CISO at Fireblocks. He previously served as global CISO at Bank Hapoalim and held both CIO and CISO roles at ClickSoftware. At Fireblocks, he led global security and enterprise technology during a period of international expansion and rising operational complexity, experience Ledger says fits its broader effort to strengthen organizational resilience.
Ledger described the combined CIO and CSO structure as a deliberate organizational change. The company said information systems and security now require closer coordination as tokenization, AI agents, and institutional digital-asset use develop together.
AI Makes Crypto Attacks Faster and More Scalable
Blatman said artificial intelligence is reducing the cost and time attackers need to search for weaknesses, while also allowing attacks to become more sophisticated and operate at greater scale. As phishing campaigns and deepfake impersonation schemes become more advanced, Ledger said security teams must evolve at a comparable pace.
The appointment follows a rise in reported crypto security incidents. Data from DefiLlama cited by Ledger shows hackers stole about $1.4 billion across 250 attacks in 2026 so far, after losses reached $2.7 billion across 146 attacks in 2025.
Recent Incidents Add Pressure on Digital Asset Defenses
Several high-profile incidents have put digital-asset companies on alert. About $320 million in Bitcoin left the Liquid Network during a hack earlier this week. Trezor also disclosed a breach involving one of its shipping providers last week, exposing personal information belonging to tens of thousands of customers. Earlier this year, a Coldcard hack raised further questions about offline wallet security.
Ledger said hardware-backed verification remains central to protecting high-value digital ownership, and pointed to secure software, resilient operations, and verifiable human intent as additional layers of protection.
Leadership Backed by Deep Security Experience
Blatman said Ledger’s hardware-security work, user trust, and Donjon research team provided a strong foundation for the role, and that he joined to connect product security, enterprise technology, and resilience. Chairman and CEO Pascal Gauthier said Ledger considers security central to its business and that Blatman’s experience protecting systems at Fireblocks and Bank Hapoalim prepared him to oversee both information technology and security.
