Anatomy of a DDoS amplification attack

Amplification attacks are one of the most common distributed denial of service DDoS attack vectors. These attacks are typically categorized as flooding or volumetric attacks, where the attacker succeeds in generating more traffic than the target can process, resulting in exhausting its resources...

Hackers Begin Weaponizing TCP Middlebox Reflection for Amplified DDoS Attacks

Distributed denial-of-service DDoS attacks leveraging a new amplification technique called TCP Middlebox Reflection have been detected for the first time in the wild, six months after the novel attack mechanism was presented in theory. "The attack … abuses vulnerable firewalls and content filteri...

DDoS Attacks Shatter Records in Q3, Report Finds

The third quarter saw the sheer volume of distributed denial-of-service DDoS attacks surge to several thousand hits per day, signaling a re-distribution of tactics by malicious actors away from cryptomining and toward the use of DDoS as a tool of intimidation, disinformation and straight-up...

Attackers Can Weaponize Firewalls and Middleboxes for Amplified DDoS Attacks

Weaknesses in the implementation of TCP protocol in middleboxes and censorship infrastructure could be weaponized as a vector to stage reflected denial of service DoS amplification attacks against any target, surpassing many of the existing UDP-based amplification factors to date. Detailed by a...

Common Firewall Feature Enables TCP Hijacking Attacks

Attackers using a feature that is common to many firewalls, switches and other networking gear could silently hijack Web sessions on mobile and desktop devices, according to a research paper presented by two Ph.D students from the University of Michigan. The two discovered that so-called TCP...
