Universal Plug and Play (UPnP) is a widely used protocol with a decade-long history of flawed implementations across a wide range of consumer devices. In this paper, we will cover how these aws are still present on devices, how these vulnerabilities are actively being abused, and how a feature/vulnerability set that seems to be mostly forgotten could lead to continued problems in the future with DDoS, account takeover, and
Over the past week, memcached reflection attacks have taken the DDoS scene by storm. With several attacks hitting organizations across many industries, including a record breaking 1.3Tbps attack against an Akamai customer. Akamai has observed a new trend in extortion attempts using memcached payloads to deliver the message.
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 the Mirai botnet and possibly the largest DDoS attack publicly disclosed. Because of memcached reflection capabilities, it is highly likely that this
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 to be used on systems that are not exposed to the Internet. There is no authentication required with memcached. When
Akamai is aware of a family of vulnerabilities known as the Key Reinstallation Attack or KRACK. These vulnerabilities abuse implementation flaws found in all modern wireless networks using WPA2. The KRACK attack is effective at the protocol level and therefore affects all systems using current WiFi encryption, including iOS, Linux, Windows and Android. The vulnerabilities allow the attacker to reinstall a previously used cryptographic key. This would allow for the
On Friday, May 12, news agencies around the world reported that a new ransomware threat was spreading rapidly. Akamai's incident response teams and researchers worked quickly to understand this new threat and how to mitigate it. This blog post is a summary of what Akamai knows at this point. Remember that this is still an evolving threat and this information may change. Akamai will update this post as we collect
Akamai has created two new WAF rules in response to new information about the Apache Struts2 vulnerability. The first rule, the most recent version of KRS Rule 3000014, is a standard part of the Kona Ruleset and protects against the many common attacks leveraging this vulnerability. This rule is designed to allow organizations that have complex environments to continue operating without risk of the WAF rule interfering with their environments.
On Monday, March 6th, the Apache team patched a vulnerability in Apache Struts2 framework. Apache Struts is an open-source web application framework for developing Java web applications. The vulnerability exists in the Jakarta Multipart parser, which can be tricked into executing attacker-provided OGNL code. The impacted versions are 2.3.5 through 2.3.31, and 2.5 through 2.5.10 of the Apache Struts framework. If you are currently running an affected version of the
Akamai SIRT has published a new case study detailing a series of DDoS attack campaigns against the MIT (Massachusetts Institute of Technology) network. So far in 2016, MIT has received more than 35 DDoS campaigns against several different targets which have been mitigated by at least one of our cloud solutions. The new case study authored by Wilber Mejia outlining the DDoS campaigns and attack methods utilized can be downloaded
