Paste sites (Pastebin, Ghostbin, Anonfiles, Rentry, and their successors) get used by attackers to publicly stage credential dumps, mailing lists, and OSINT compilations. Executive email addresses — CEO, CFO, principal, chief of staff, general counsel — are the most valuable line items in those dumps because they map directly to wire-authority workflows. ## Why attackers exploit it A pretext-attack chain starts with a target list. Paste-site scraping produces a target list for free. The attacker cross-references executive emails against LinkedIn seniority, company wire volume, and known advisor-tenant relationships (accountant, wealth manager, law firm) to pick the highest-yield targets before staging the actual attack. ## Remediation direction Continuous paste-site monitoring with alerts on executive email addresses appearing in any new dump, plus a takedown workflow for content that hosting providers will honor. Executives themselves benefit from a personal email hygiene review — legacy accounts on breached consumer services are the entry vector for most paste-site inclusions.
