Pastefy is abused by the Laundry Bear threat actor as a dead drop resolver to dynamically distribute DRILLAPP C2 addresses, a technique that allows C2 infrastructure rotation without recompiling the backdoor and complicates static blocklist-based defenses. Pastefy itself is not compromised; it is a legitimate paste service exploited for its open accessibility and trusted domain reputation. Organizations should monitor or block egress to pastefy.app and similar paste services (pastebin.com, paste.ee) in non-developer environments, treating such connections as potential C2 retrieval indicators when correlated with other DRILLAPP behavioral signals.
