sender

Contact the sender through known channels, not the suspicious message.

Hard copies of the travel records that arrive from other states are destroyed without notification to the sender, agency officials said.

Last Saturday, a Telegram message popped up on Heejin’s phone from an anonymous sender.

Aleksandr Valentij of cybersecurity company Surfshark suggested checking the sender’s email address carefully to see if it doesn’t precisely match the name of the organization they purportedly represent, and looking for typos or grammatical errors — two telltale signs of a scam.

The mysterious sender also noted that there was more material to come, including “legal and court documents to internal campaign discussions.”
