New SLP Vulnerability Could Let Attackers Launch 2200x Powerful DDoS Attacks

New SLP Vulnerability Could Let Attackers Launch 2200x Powerful DDoS Attacks

Apr 25, 2023 Network Security / DDoS
Details have emerged about a high-severity security vulnerability impacting Service Location Protocol ( SLP ) that could be weaponized to launch volumetric denial-of-service attacks against targets. "Attackers exploiting this vulnerability could leverage vulnerable instances to launch massive Denial-of-Service (DoS) amplification attacks with a factor as high as 2,200 times, potentially making it one of the largest amplification attacks ever reported," researchers Pedro Umbelino from Bitsight and Marco Lux from Curesec  said  in a report shared with The Hacker News. The vulnerability, which has been assigned the identifier CVE-2023-29552  (CVSS score: 8.6), is said to impact more than 2,000 global organizations and over 54,000 SLP instances that are accessible over the internet. This includes VMWare ESXi Hypervisor, Konica Minolta printers, Planex Routers, IBM Integrated Management Module (IMM), SMC IPMI, and 665 other product types. The top 10 countries with the most o

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

Mar 09, 2022
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, gaming firms, and other organizations. "Approximately 2,600 Mitel MiCollab and MiVoice Business Express collaboration systems acting as PBX-to-Internet gateways were incorrectly deployed with an abusable system test facility exposed to the public Internet," Akamai researcher Chad Seaman said in a joint advisory . "Attackers were actively leveraging these systems to launch reflection/amplification DDoS attacks of more than 53 million packets per second (PPS)." DDoS reflection attacks typically involve spoofing the IP address of a vic

Sailing the Seven Seas Securely from Port to Port – OT Access Security for Ships and Cranes

Oct 28, 2024Operational Technology / Cybersecurity
Operational Technology (OT) security has affected marine vessel and port operators, since both ships and industrial cranes are being digitalized and automated at a rapid pace, ushering in new types of security challenges. Ships come to shore every six months on average. Container cranes are mostly automated. Diagnostics, maintenance, upgrade and adjustments to these critical systems are done remotely, often by third-party vendor technicians. This highlights the importance of proper secure remote access management for industrial control systems (ICS).  Learn more in our Buyer's Guide for Secure Remote Access Lifecycle Management .  We at SSH Communications Security (SSH) have been pioneering security solutions that bridge the gap between IT and OT in privileged access management . Let's investigate how we helped two customers solve their critical access control needs with us.

Attackers Can Weaponize Firewalls and Middleboxes for Amplified DDoS Attacks

Attackers Can Weaponize Firewalls and Middleboxes for Amplified DDoS Attacks

Aug 16, 2021
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 Colorado Boulder at the USENIX Security Symposium, the volumetric attacks take advantage of TCP-non-compliance in-network middleboxes — such as firewalls, intrusion prevention systems, and deep packet inspection (DPI) boxes — to amplify network traffic, with hundreds of thousands of IP addresses offering  amplification factors  exceeding those from DNS, NTP, and Memcached. The research, which received a Distinguished Paper Award at the conference, is the first of its kind to describe a technique to carry out DDoS reflected amplification attacks over the TCP protocol by abusing middlebox misconfigurations in the wild
