About BlockThreat
The Concept
The Blockchain Threat Intelligence newsletter brings together the most important developments in blockchain security in a single trusted source. It covers the full spectrum of risks and trends shaping the ecosystem, from exploits and vulnerabilities to phishing campaigns, malware strains, supply chain attacks, policy updates, and industry events such as conferences, competitions, and CTFs. It also highlights the human side of security, chronicling criminal investigations and notable prosecutions to show how accountability shapes the space.
Each week, subscribers receive carefully curated research, technical write ups, and blockchain security tools gathered from hundreds of sources. Many creators and researchers consider it an honor to have their work featured, making the newsletter a recognized hub for valuable contributions. This curation saves readers hours of work while keeping them informed about emerging threats, new techniques, and innovative tools that help them stay ahead in a rapidly evolving ecosystem.
At its heart, the newsletter reflects a personal mission to help builders, defenders, and users understand threats, improve security, and make the blockchain ecosystem safer and more accessible for everyone. By combining technical analysis, industry insight, criminal chronicles, and curated research, it provides context, actionable intelligence, and a clear view of the blockchain security landscape.
The Editor
Peter Kacherginsky is a seasoned security practitioner and active member of the blockchain security community. He has presented at conferences including Defcon and the DeFi Security Summit, won multiple CTF competitions and security contests including the IDA Pro Plugin Contest, and authored several open source security tools included in Kali Linux and other major security distributions.
Before entering the cryptocurrency space, Peter worked as a malware reverse engineer, penetration tester, and incident responder, helping secure some of the most critical government and private sector systems. When he first encountered cryptocurrency, he was struck by its potential to provide open, permissionless access to financial infrastructure, especially for people excluded from traditional systems. Blockchain became a deeply personal mission, a rare opportunity to build technology that could meaningfully improve lives on a global scale.
Since then, Peter has applied his expertise in threat research, incident response, pentesting, and adversarial analysis to the emerging and high stakes field of blockchain security. In 2019, he launched the Blockchain Threat Intelligence newsletter after recognizing the absence of a publication dedicated to understanding how real attacks unfold in crypto and what defenders can learn from them. What began as a personal effort to study incidents has grown into a long running weekly publication and a passion project dedicated to documenting, analyzing, and sharing lessons from blockchain security incidents, helping builders, defenders, and users rely on systems that are safer, more resilient, and worthy of trust.
