“Please review the attached diplomatic briefing document.” Would you open it? BITTER APT sent files dressed as diplomatic and military documents to government, energy, and engineering teams in South Asia. Opening one could install PapRAT spyware. Here’s the tell: sensitive-looking doesn’t mean authentic. If you weren’t expecting the briefing, and can’t confirm the sender or why you got it, don’t trust the attachment. Before opening an unexpected briefing, confirm it with the sender using a contact method you already know.
