Our exploration of methods for normalizing the number of web application attacks sourced by each country has only considered contextual variables from external sources that characterized each country in a context devoid from Akamai, so far. This final leg of the journey will situate the attack counts within a context that is specific to Akamai and the characteristics of the attacks themselves.
On the week of July 15th, researcher Juha-Matti Tilli disclosed a vulnerability in the Linux kernel to the kernel maintainers, the National Cyber Security Center - Finland (NCSC-FI), CERT Coordination Center (CERT/CC), and Akamai. The vulnerability, CVE-2018-5391, is a resource exhaustion attack triggered by a specially crafted stream of IP datagrams that cause expensive processing within the Linux kernel. This vulnerability is similar to the Linux TCP vulnerability announced August,
In the last installment, we introduced the challenge of normalizing a geographic visualization showing the observed number of web application attacks sourced from each country. This time, we'll try to discern which potential normalizing variables could have a significant relationship with the attack counts through exploratory analysis and hopefully gain some new insights.

The vulnerability, CVE-2018-5390, is a resource exhaustion attack triggered by a specially crafted stream of TCP segments which creates expensive processing within the Linux kernel. In preparation for the public disclosure of the vulnerability,
I recently attended Thotcon in Chicago, where I saw a presentation by Avishay Zawoznik called, "V!4GR4 BotNet: Cyber-Crime, Enlarged". It describes the processes, by a black hat, that used SQL injection to inject Viagra spam into vulnerable websites. The main takeaway was that the speaker talked about how compromised wordpress websites were used as webshells to operate the spam campaign from. I originally was under the assumption that websites were
Written by the Akamai Threat Research Team Akamai Threat Research has observed an increase in attacks attempting to exploit a recent Drupal vulnerability (CVE-2018-7600). Much like recent vulnerabilities in Apache Struts, attackers have attempted to use this exploit for remote command injection attacks and to harness the power of the botnet to join a herd of coin-miners for profit. While the attacker did not use a large number of machines
Written by Lisa Beegle OVERVIEW Operation #OpIcarus2018 has been announced and it encompasses several on-going campaigns, including #OpPayBack, #OpIcarus, #DeleteTheElite, and #SosNicaragua. The attack campaign(s) are being driven by actors using Anonymous iconography and ideological motives. These malicious actors have stated their intent to attack various banking institutions between June 21 through 28 2018. Targeted enterprises need to be on heightened alert leading up to these dates, as there are
Why do we need a Knowledge Base system Let me start with an obvious statement: the Internet generates a lot of data. Every day we, Akamai's security research teams, see billions of DNS queries, millions of domains, and who knows how many IP addresses. This is an exciting thing, especially if you're a data scientist. In the past year, we have taken on a "simple task": to map the "dark
Ryan Barnett, Principal Security Researcher, Akamai Elad Shuster, Senior Security Researcher, Akamai During its research into Credential Abuse attack campaigns, Akamai's threat research team conducted an analysis of web logins to gain insights into how widespread the adoption of API-based logins is and whether or not this trend also affects attackers and attack campaigns. It will come as no surprise that API-based logins are highly targeted by credential abuse attackers
