CVE-2017-5972

CVE-2017-5972 affects the Linux kernel 3.x TCP stack. The issue is that SYN cookies protection is not correctly applied for fast-network connection scenarios, enabling remote attackers to cause CPU denial of service by sending a flood of TCP SYN packets (as demonstrated against kernel-3.10.0 in C...

New Large-Scale DDoS Attacks Follow Schedule

A powerful new botnet is being blamed for massive and sustained DDoS attacks that security researchers at CloudFlare compare to Mirai when it comes to intensity and scope. The attacks began Nov. 23 and ran for eight hours daily, similar to an average workday. The consistent attacks occurred for...

SOL68401558 - BIG-IP virtual server TCP sequence numbers vulnerability

Vulnerability Recommended Actions If you are running a version listed in the Versions known to be vulnerable column, you can eliminate this vulnerability by upgrading to a version listed in the Versions known to be not vulnerable column. If the table lists only an older version than what you are...

Dyn DDoS Could Have Topped 1 Tbps

As more time passes, researchers are getting insight into the size and structure of the DDoS attack against DNS provider Dyn last week, and the capabilities of the Mirai botnet. First, Dyn released a truncated post-mortem on the attack with admittedly some omissions as a law enforcement...

IoT Botnet Uses HTTP Traffic to DDoS Targets

The IoT botnet behind some of the largest publicly recorded DDoS attacks is flooding its targets with HTTP traffic, generating more than one million requests per second in some cases, in order to bring down web applications. The attacks were recorded prior to the release of the source code fuelin...
