If you use a Coldcard hardware wallet, please pay attention. If you know someone who uses one, call them. Text them. This appears to be one of the most serious wallet security incidents Bitcoin has seen. If you're affected, don't wait. If you need help, reach out.

COLDCARD BTC MIGRATION VIDEO Here is an explainer video showing you how to do two things: 1. Set up a Casa multisig with your current Coldcard and send the assets from the Coldcard to the multisig. This eliminates the risk of loss from the CC vulnerability. Useful for people who only have a CC and don't want to send to an exchange or hot wallet. 2. Second part of the video (starting around minute 7) shows moving assets out of the Coldcard Mk3 single sig. This might be useful for anyone trying to move their assets right now that hasn't touched their CC in 4 years. Doing this was a fun reminder of how using a Coldcard outside of Casa is still surprisingly hard even though I know the gist of it and have been doing this for 8 years 😂. If you want help migrating to Casa, DM me or the Casa account and we will direct you to the team.

🚨 THIS IS MASSIVE: Claims that NANCY PELOSI was warned about a serious security risk and still kept SWALWELL in a sensitive role raise HUGE questions. National security isn’t partisan. It’s foundational. If there were warnings, why wasn’t action taken?

Users who have Python installed on their PCs and use WhatsApp Desktop may be exposed to a security risk. A specially crafted .pyz (Python archive) file can be used to execute malicious code upon a single click, potentially compromising the system. A similar vulnerability was previously identified in Telegram Desktop and has since been remediated. At present, Meta does not recognize this behavior as a security issue, which may leave WhatsApp Desktop users at risk of exploitation.

CVE-2025-68613: n8n RCE Vulnerability Exploit/PoC: n8n has a critical security flaw that lets authenticated users execute arbitrary code through its workflow expression system. When users configure workflows, the expressions they provide can sometimes be evaluated without proper isolation from the underlying runtime environment.
