Security researchers at Lumen's Black Lotus Labs reported a large-scale destructive incident dubbed “Pumpkin Eclipse” in which unknown attackers used the Chalubo RAT to deliver a malicious firmware update that permanently disabled over 600,000 ActionTec T3200/T3260 routers within a single ASN over a 72-hour period in October 2023; the attack required hardware replacement for affected devices and has no confirmed nation-state attribution.
