New threats continually emerge, targeting critical infrastructure and posing significant risks to businesses globally. One cyber threat making a dangerous return is BrickerBot, a malicious botnet responsible for powerful Permanent Denial of Service (PDoS) attacks. Radware’s recent threat advisory highlights the resurgence of BrickerBot, which is now more sophisticated and potentially more destructive than ever before.
What is BrickerBot and Why Should You Care?
BrickerBot is a botnet designed to carry out Permanent Denial of Service (PDoS) attacks. Unlike typical DDoS (Distributed Denial of Service) attacks that overload a system with traffic, PDoS attacks aim to permanently damage or destroy devices by exploiting vulnerabilities and overwhelming them with malicious commands. The ultimate goal of BrickerBot is to render targeted devices inoperable, making them either inoperable or so damaged that they must be replaced, rather than simply slowed down or interrupted temporarily.
The botnet itself comprises a network of compromised IoT (Internet of Things) devices, which are notoriously vulnerable due to their weak security protocols. These devices—ranging from home routers and cameras to more critical industrial equipment—are used as pawns in the attack, with the botnet sending destructive commands to erase essential data, corrupt firmware, or cause irreparable damage.
The Resurgence of BrickerBot
Our latest advisory underscores the renewed threat posed by BrickerBot, which has returned with even more advanced techniques. This newer iteration of the botnet takes advantage of more vulnerabilities and can scale its attacks to target even larger and more diverse systems. The damage it inflicts is not temporary, making it especially concerning for businesses and industries reliant on critical infrastructure.
The return of BrickerBot signals a shift in the strategy of cybercriminals. Instead of just interrupting services temporarily (as with a typical DDoS attack), the goal of BrickerBot is to create lasting damage. The financial impact can be enormous as businesses may need to replace damaged devices, repair affected systems, and recover from the destruction caused by the attack. In addition, the reputation and customer trust of targeted businesses can be severely impacted, with long-term consequences.
How BrickerBot PDoS Attacks Work
The key to BrickerBot’s power lies in its use of known vulnerabilities in unsecured IoT devices. The botnet takes control of thousands of vulnerable devices, often without their owners’ knowledge, and launches a devastating attack by sending commands that overwrite system files, corrupt firmware, and cause irreparable damage. Unlike traditional DDoS attacks, the effect of a BrickerBot attack is permanent, requiring the affected systems to be replaced or extensively repaired, causing significant disruption.
Moreover, the botnet is designed to be stealthy and evasive, making it difficult for security systems to detect and block before the damage is done. As more devices become connected in the Internet of Things, the attack surface for BrickerBot continues to expand, making it a growing threat for organizations across sectors.
