ZeffSec is a hacktivist collective focused on infrastructure-level disruption and exposing vulnerabilities in centralized digital networks. In March 2026, the group claimed responsibility for a large-scale DDoS attack against ArvanCloud, Iran's primary cloud and CDN provider, causing widespread service outages across platforms including the online education service Skyroom. The group announced the operation via Telegram, stating their goal was disruption of centralized infrastructure rather than data theft.
