What happens when you take away cybercriminals’ most expensive toy? They get angry and attack. When courageous security researchers decided to paralyze over 500 command servers of the notorious IoT botnets Kimwolf and Aisuru, the hackers reacted promptly: They launched massive revenge attacks on the researchers, whose data packets were filled to the brim with […]

Not all DDoS attacks have the same objective. Some are designed simply to overload, while others are intended to conceal something more nefarious. A massive increase in requests immediately raises red flags in every SOC. However, when millions of requests flood the infrastructure in a short period, standard diagnosis often falls short. At first glance, the case seems clear: a classic […]

In IT security, the following principle often applies: introduce a new tool for every new problem. As a result, many companies have developed a digital patchwork quilt over time. Endpoint protection here, firewalls there, identity management, DDoS protection, WAF, bot management, and API security—everything was purchased, configured, and operated individually. On paper, this looks like seamless coverage. In operational reality, however, […]

Web applications are the backbone of modern businesses. They serve as sales platforms, customer interfaces, and process engines. There is no question that this infrastructure must be protected. But in an IT landscape that is rapidly evolving toward APIs and microservices, one thing remains constant: standing still means risk. In light of this, is the classic protection approach still sufficient? […]

DDoS attacks are often perceived as immediate disruptive actions. Servers become unavailable, websites crash, and services fail. But not every attack has this goal. A recent attack campaign shows that DDoS attacks are increasingly being used as a tool for preparation, analysis, and testing—quietly, persistently, and strategically. A recent attack, which initially appeared unspectacular, showed a familiar pattern at first glance: a […]

Volumetric DDoS attacks typically follow a clear pattern: a brief buildup followed by a sudden peak, often within seconds. The target is flooded with traffic until the attackers exhaust their resources, or a mitigation system takes over. However, in the incident described below, a different scenario unfolded. Over the course of several hours, one actor […]
