State of the Internet/ Security Volume 5, Issue 4 - ...
The cliché "follow the money" is exactly what criminals do when targeting the financial services vertical. In the State of the Internet/ Security, Volume 5, Issue 4, we take a deeper dive into how credential stuffing and web attacks are impacting one of the world's most powerful industries.
Criminals using targeted Remote File Inclusion attac ...
In June 2019, logs on my personal website recorded markers that were clearly Remote File Inclusion (RFI) vulnerability attempts. The investigation into the attempts uncovered a campaign of targeted RFI attacks that currently are being leveraged to deploy phishing kits. The latest kit focuses on a large and well-known bank in the EU.
Adversarial DGA - Is It Out There?
The Caveats of Inline DGA Mitigation Domain generation algorithms (DGAs) are often implemented by botnets to produce a large number of domain names that bots will use to communicate with their command and control (C2) servers. Accordingly, identifying algorithmically generated domains (AGD) in network traffic is a key aspect for analyzing, detecting and possibly mitigating botnet behavior. There are three main approaches for identifying AGDs: (1) predictive mitigation, (2) offline
Pykspa v2 DGA updated to become selective
Additional research and information provided by Asaf Nadler Recent changes to the Pykspa v2 domain generation algorithm (DGA) have made it more selective. Akamai researchers have tracked these changes and believe that part of the reason for selective domain generation is to enable attackers to keep a smaller footprint online, and remain undetected for longer periods. However, it is still possible to brute-force the DGA and track the domains. In
Anatomy of a SYN-ACK attack
Overview In recent weeks, a series of DDoS attacks were directed at multiple financial institutions. The attacks utilized a seldom seen reflection vector known as TCP SYN-ACK reflection. SYN-ACK reflection isn't new, but it's rarely observed due mostly to its lack of popularity among attackers and impact on the victim. The observed attacks sparked conversations both publicly and privately amongst several organizations, including Akamai. In this write-up, we're going to
SIRT Advisory: Silexbot bricking systems with known ...
On June 25th, I discovered a new bot named Silexbot on my honeypot. The bot itself is a blunt tool used to destroy IoT devices. Its author, someone who claims to be a 14-year-old boy from Europe, has made his intentions clear with some very distinct text embedded in the code.
Analytics - Tracking a Phishing Campaign
Earlier this year, Akamai discovered a publicly available plug-in that is being used to collect analytics and various stats on a number of phishing campaigns. Using our own data, we were able to correlate the analytics and view the IP addresses of the victims, since the phishing campaigns were directing victims to one of our customers.
CloudTest Vulnerability (CVE-2019-11011)
On March 3, 2019, Rio Sherri from MDSec discovered, and responsibily disclosed, an unauthenticated remote command execution (RCE) vulnerability in CloudTest, that affects all versions prior to 58.30. This vulnerability has been assigned to CVE-2019-11011. The discovered vulnerability existed due to an unsafe Java deserialization between certain parameters. After extensive testing, Akamai released a patch on March 7, 2019 and made it available to all CloudTest customers.
Latest ECHOBOT: 26 Infection Vectors
Introduction Since the release of the Mirai source code in October of 2016, there have been hundreds of variants. While publishing my own research, I noticed that Palo Alto Networks was also examining similar samples, and published their findings. Earlier this month, not too long after Palo Alto Networks published their report, I discovered a newer version of Echobot that uses 26 different exploits for its infection vectors. In some
