VERY IMPORTANT

Following Black Hat and DEF CON conferences, a threat actor targeted attendees through X direct messages, posing as CoinDesk's VP and Head of Marketing to establish trust under the pretext of conference planning. The campaign employed a malicious Google Apps Script embedded in a Google Doc that presented ClickFix-style instructions and manual download options. The attack delivered different payloads based on the victim's operating system: macOS users received AMOS infostealer, while Windows users were infected with NetSupport RAT, a Ledger wallet implant, and a TLS-intercepting proxy. A secondary lure masqueraded as a DocSend installer to deliver additional payloads. The operation demonstrated sophisticated social engineering by leveraging trusted platforms and post-conference networking expectations.
