Frequently asked questions
Can deleted chats or files become evidence?
Sometimes, depending on device state, backups, cloud sync, forensic recovery and platform records. Delay may reduce chances of recovery.
Why is chain of custody important?
It helps show who handled the evidence, when and how, reducing disputes about tampering or reliability.
Can screenshots alone prove a cyber crime?
Screenshots may help, but stronger evidence often includes metadata, platform records, device data and corroborating logs.
Do businesses need forensic imaging before internal action?
In serious matters, forensic preservation before disciplinary or legal action can prevent evidence loss and improve reliability.
