Casa Launches Four Security Features To Combat Rising Social Engineering Attacks On Bitcoin Holders

Casa released four features aimed at social engineering, the dominant cause of crypto theft. Guardian Mode adds a human checkpoint by requiring two Casa Advisors to complete a live video verification call before the Recovery Key can sign a transaction, followed by a 48-hour hold that allows reversal. Disabling Guardian Mode requires the same verification call and 48-hour delay to prevent attackers from removing protection in the same session. Whitelisting restricts vault withdrawals to pre-approved addresses, with new addresses subject to a 48-hour waiting period and email alerts. Turning off Whitelisting also triggers a 48-hour hold to block rapid attacker changes.

"Guardian Mode adds a human checkpoint to every transaction. When enabled, the Casa Recovery Key will not sign a transaction until two Casa Advisors complete a live video verification call with the account holder. After that call, a 48-hour hold activates before the signature is applied. The window gives users the ability to reverse course if they acted under pressure. Disabling Guardian Mode follows the same process - a verification call plus a 48-hour delay - so an attacker cannot strip the protection and strike in the same session."

"Whitelisting restricts vault withdrawals to a list of pre-approved addresses. Any new address added to the list enters a 48-hour waiting period before it becomes active. During that window, Casa sends an email alert to the account holder. The delay is designed to interrupt a core element of social engineering: the manufactured urgency that pushes victims to send funds before they reconsider. Turning off Whitelisting carries its own 48-hour hold, preventing an at"

"Social engineering - where scammers manipulate victims into sending funds or handing over wallet access - now dwarfs other forms of crypto theft. For every physical attack on a crypto holder reported in 2025, there were more than 2,000 phishing attacks filed with the FBI."

"“Social engineering is the lowest of the low,” Neuman wrote. “People are trying to trick others into losing their life savings. We will not stand for it.”"
