Threats to Executives & Public Figures

Reported by Balkan Insight. [6]

Nikkei Inc.: The publisher says stolen credentials let attackers into a development cloud on Oct. 7. About 150,000 leaked records contain names, emails, postal addresses, phone numbers or birth dates. [27]
Action: Business-media subscriber lists are a natural target for anyone hunting executives. If your principals subscribe to Nikkei, expect targeted phishing using their real details.

Tradecraft Tip (general guidance, not tailored advice)
Run a mailroom refresher this weekend. With letters still in the postal system, remind everyone who handles mail at the office and the residence of the basics: don’t shake, sniff or open suspect envelopes; set them down, leave the room, close the door, wash hands and call 911. Watch for excess postage, multiple postmarks, no or mismatched return addresses, misspelled names, stains, powder or lumps. Keep a simple log of who touched an item and when, which saves time when responders arrive.
