Operation Payback

The operation was triggered by the decision of major financial institutions to halt the processing of donations to WikiLeaks. This action occurred in the wake of WikiLeaks' publication of the US diplomatic cables (Cablegate), which generated significant international controversy and pressure from the US government. In response, Anonymous mobilized its members to launch a massive Distributed Denial of Service (DDoS) attack. Using tools like the Low Orbit Ion Cannon (LOIC), thousands of participants flooded the targeted websites with traffic, successfully disrupting online services and payment processing capabilities. The attacks caused significant operational disruption, forcing companies like PayPal to estimate substantial financial losses and leading to subsequent legal action against several participants.

The context for Operation Payback was the release of the US diplomatic cables by WikiLeaks in 2010. These documents exposed sensitive diplomatic communications, leading to intense international scrutiny and pressure on organizations that facilitated financial transactions, ultimately resulting in the suspension of donations to WikiLeaks.

The attack utilized a classic DDoS methodology, specifically volumetric flooding. The Low Orbit Ion Cannon (LOIC) was a widely available tool used to generate high volumes of connection requests, overwhelming the target servers' capacity to handle legitimate traffic. The goal was not data theft, but service disruption, making the websites inaccessible to users.
