Hackers Abuse Mitel Devices to Amplify DDoS Attacks by 4 Billion Times

Threat actors have been observed abusing a high-impact reflection/amplification method to stage sustained distributed denial-of-service (DDoS) attacks for up to 14 hours with a record-breaking amplification ratio of 4,294,967,296 to 1. The attack vector – dubbed TP240PhoneHome (CVE-2022-26143) – has been weaponized to launch significant DDoS attacks targeting broadband access ISPs, financial institutions, logistics companies, […]

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 group of academics from the University of Maryland and the University of […]
