While using a computer, all the data manipulated is written temporarily in [[!wikipedia Random-access_memory desc="RAM"]]: texts, saved files, but also passwords and encryption keys. The more recent the activity, the more likely it is for the data to still be in RAM.
Ao usar um computador, todos os dados manipulados são escritos temporariamente na [[!wikipedia Random-access_memory_pt Memória_de_acesso_aleatório desc="memória RAM"]]: textos, arquivos salvos, e também senhas e chaves criptográficas. Quanto mais recente a atividade, maior é a probabilidade de que estes dados estejam na RAM.

<p>See how we implement this [[memory
erasure|contribute/design/memory_erasure]], for example, if you want to
implement this feature outside of Tails.</p>

<p>In a <a
href="https://www.forensicfocus.com/stable/wp-content/uploads/2011/08/cold_boot_attack_for_forensiscs1.pdf">research
report from 2011</a>, Defense Research and Development Canada concluded that
cold boot attacks can be useful in some cases to acquire data in memory but are
not a panacea and have many drawbacks dictated by the laws of physics, which
cannot be overcome by the technique. The authors recommend to only use cold
boot attacks as a last resort when all other avenues have been exhausted.</p>

<p>As far as we know, cold boot attacks are not a common procedure for
data recovery.</p>

After a computer is powered off, the data in RAM disappears rapidly, but it can remain in RAM up to several minutes after shutdown. An attacker having access to a computer before the data in RAM disappears completely could recover important data from your session.
Depois que um computador foi desligado, os dados na RAM desaparecem rapidamente, mas podem continuar na RAM até alguns minutos depois do desligamento. Um atacante que tenha acesso ao computador antes de que estes dados desapareçam completamente pode recuperar dados importantes de sua sessão.
