memcached: UDP server support allows spoofed traffic amplification DoS

It was discovered that the memcached connections using UDP transport protocol can be abused for efficient traffic amplification distributed denial of service DDoS attacks. A remote attacker could send a malicious UDP request using a spoofed source IP address of a target system to memcached, causi...

Attackers Use UPnP to Sidestep DDoS Defenses

Universal Plug and Play networking protocols have never been a friend of security researchers. On Monday, Imperva gave the InfoSec community another reason to dislike UPnP. In a proof-of-concept Distributed Denial of Service DDoS attack, Imperva researchers have devised a way to exploit the UPnP...

New DDoS Attack Method Demands a Fresh Approach to Amplification Assault Mitigation

Amplification attack vectors are some of the most commonly used tools in the DDoS attacker’s arsenal. In the last quarter of 2017, we saw NTP amplification employed in roughly 33 percent of all DDoS assaults against our customers, while DNS and SSDP amplification vectors played a part in 17 perce...

Mirai Variant Targets Financial Sector With IoT DDoS Attacks

A variant of the Mirai botnet was used to launch a series of distributed denial of service campaigns against financial sector businesses. The attacks utilized at least 13,000 hijacked IoT devices generating traffic volumes up to 30 Gbps, considerably less intense than the original Mirai assaults...

Cryptomining is all the rage among hackers, as DDoS amplification attacks continue

In this week’s InfoSec news review we’ll dive into cryptomining, get the latest on DDoS amplification, go over recent data breaches, and check out another vendor claiming it can crack iPhones.
