Our Exposed World – Old exposures, new attacks

Natasha Hellberg, Senior Threat Researcher FTR With assistance from William Gamazo Sanchez, DSLabs Within the last few days a new player has been introduced into the distribute denial of service DDoS amplification attack world and with it brings the potential for much larger DDoS attacks than wha...

Red Hat Releases Security Guidance for Memcached

Red Hat has released security recommendations to address potential Distributed Denial of Service attacks using Memcached. This misconfiguration could allow an attacker to exploit Memcached services as a reflection and amplification vector, causing unexpected volumes of traffic to be sent to...

Powerful New DDoS Method Adds Extortion

Attackers have seized on a relatively new method for executing distributed denial-of-service DDoS attacks of unprecedented disruptive power, using it to launch record-breaking DDoS assaults over the past week. Now evidence suggests this novel attack method is fueling digital shakedowns in which...

Biggest-Ever DDoS Attack (1.35 Tbs) Hits Github Website

On Wednesday, February 28, 2018, GitHub's code hosting website hit with the largest-ever distributed denial of service DDoS attack that peaked at record 1.35 Tbps. Interestingly, attackers did not use any botnet network, instead weaponized misconfigured Memcached servers to amplify the DDoS attac...

Inside a New DDoS Amplification Attack Vector via Memcached Servers

We recently saw a new DDoS amplification attack vector via memcached servers that culminated in two massive DDoS amplification attacks on February 28. Both attacks were mitigated successfully. Here’s how memchached servers work and how the attacks unfolded. Memcached servers Unless updated within...

Memcached-fueled 1.3 Tbps attacks

At 17:28 GMT, February 28th, Akamai experienced a 1.3 Tbps DDoS attack against one of our customers, a software development company, driven by memcached reflection. This attack was the largest attack seen to date by Akamai, more than twice the size of the September, 2016 attacks that announced th...

Misconfigured Memcached Servers Abused to Amplify DDoS Attacks

Cybercriminals behind distributed denial of service attacks have added a new and highly effective technique to their arsenal to amplify attacks by as much as 51,200x by using misconfigured memcached servers accessible via the public internet. The technique was reported by Akamai, Arbor Networks a...

Memcached Servers Abused for Massive Amplification DDoS Attacks

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 days, security researchers at Cloudflare, Arbor...

Memcached UDP Reflection Attacks

Akamai is aware of a new DDoS reflection attack vector: UDP-based memcached traffic. Memcached is a tool meant to cache data and reduce strain on heavier data stores, like disk or databases. The protocol allows the server to be queried for information about key value stores and is only intended t...

Memcached Stats Amplification Scanner

This module can be used to discover Memcached servers which expose the unrestricted UDP port 11211. A basic "stats" request is executed to check if an amplification attack is possible against a third party. Module Options msf use auxiliary/scanner/memcached/memcached/amp msf undefinedamp show...

New Rapidly-Growing IoT Botnet Threatens to Take Down the Internet

Just a year after Mirai—biggest IoT-based malware that caused vast Internet outages by launching massive DDoS attacks—completed its first anniversary, security researchers are now warning of a brand new rapidly growing IoT botnet. Dubbed 'IoTreaper,' first spotted in September by researchers at...

Network Time Protocol Control Mode Unauthenticated Trap Information Disclosure and DDoS Amplification Vulnerability(CVE-2016-9310)

Summary An exploitable configuration modification vulnerability exists in the control mode mode 6 functionality of ntpd. A specially crafted control mode packet can set ntpd traps, providing information disclosure and DDoS amplification, and unset ntpd traps, preventing legitimate monitoring. A...
