I have been playing close attention to Internet of Things (IoT) malware targeting systems with Telnet enabled, while also collecting samples targeting systems with SSH enabled on port 22. I've collected over 650 samples landing in my honeypot within the last week. The earliest sample showed up on July 24th at 20:06. The honeypot allows logins using known default login credentials for root.
On Tuesday, August 13th at 10 AM Pacific Time (1700UTC), Netflix publicly disclosed a series of vulnerabilities found by Jonathan Looney that impact many implementations of the HTTP2 protocol. A vulnerability found by Piotr Sikora of Google was also released at the same time. Akamai is grateful to the reporters for their work and pre-release coordination.
As phishing websites become more advanced, by using rich functionality and customized workflows, evidence indicates that web analytics plugins are being commonly used in phishing kits. This enables threat actors to have stronger visibility into victim profiles and their behavior once they have landed on the scam website. This, in turn, can lead to future optimizations of the phishing kit and scam's distribution.
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.
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.
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
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
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
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.
