Security researchers have discovered a “kill switch” that could help companies protect their websites under massive DDoS attack launched using vulnerable Memcached servers.
Massive Memcached reflection DDoS attacks with an unprecedented amplification … Continue reading ‘Kill Switch’ to Mitigate Memcached DDoS Attacks — Flush ‘Em All
Two separate proofs-of-concept (PoC) exploit code for Memcached amplification attack have been released online that could allow even script-kiddies to launch massive DDoS attacks using UDP reflections easily.
The first DDoS tool is written in C progra… Continue reading Memcached DDoS Exploit Code and List of 17,000 Vulnerable Servers Released
GitHub suffered and survived a record 1.35-terabit-per-second denial of service attack on Wednesday, an unprecedented deluge of traffic that’s spotlighting just how powerful “amplification attacks” can be — and a new attack vector experts predict is about to become a lot more common. The top comment on the Hacker News discussion says it all: “Wow, 1.35Tbps? That’s a lot for a DoS attack, right?” It’s still early in 2018, but that could be the understatement of the year so far. Wednesday’s attack counts as the most powerful denial of service barrage against a single site in history. It’s significantly larger than the size of the 2016 Mirai botnet attacks that brought down a host of the internet’s biggest websites through an attack on Dyn that rippled out to other sites dependent on the company’s infrastructure and DNS services. GitHub went down a number of times during this week’s attack until traffic was moved to […]

Cybercriminals have figured out a way to abuse widely-used Memcached servers to launch over 51,000 times powerful DDoS attacks than their original strength, which could result in knocking down of major websites and Internet infrastructure.
In recent d… Continue reading Memcached Servers Abused for Massive Amplification DDoS Attacks
