What is the Context of Physical Attack?

Physical attacks are a pertinent security concern for users of hardware wallets and other devices holding significant digital assets. News reports frequently detail incidents where physical manipulation or access to devices has led to unauthorized fund transfers. Security professionals continually develop countermeasures to fortify hardware against these direct threats.

Physical Attack

Definition

A Physical Attack is a security threat that involves direct, tangible interaction with a device or system to compromise its integrity or extract information. This can range from tampering with hardware to intercepting signals or forcing access. Such attacks bypass many traditional software-based security measures.
