Old IoT Botnet has been Revived

The “Hello, Peppa!” botnet and the /ept/out.php vulnerability were newly discovered attacks by our Attack Vector Miner. But now, it has recognized the reactivation of a forgotten IoT botnet. This botnet exploits the D-Link router DSL-2750B  remote command execution. What does the attack look like?  The discovered pattern is the /login.cgi?cli= as you can see below:  In the case of the D-Link router DSL-2750B firmware 1.01 to 1.03, there’s an option for remote command execut...

New Zero-Day Vulnerability on the Horizon Again

After the “Hello, Peppa!”  zero-day botnet, our Attack Vector Miner detected another zero-day vulnerability.  Some vulnerable websites contain an /ept/out.php file, which can work as an open proxy. That’s why the attacker scans the /ept/out.php file. Let’s see an example:  The number of these attacks started to increase on July 11th, and as we can see in the diagram below, the botnet’s activity is slowing down now.  During the peak time, we experienced 15.000 attacks per day and most of them tar...

New Botnet Has Been Discovered – “Hello, Peppa!”

Our Attack Vector Miner (based on AI) is a very effective tool to identify 0. day attacks. Here comes the first catch! Discovery of a New Botnet At the beginning of July, our Attack Vector Miner created a new cluster, filled with logs about a new type of botnet. We perceived the first incident on 16th June from an Indian IP address (106.51.152.115). The first incident of the "Hello Peppa!" botnet Since then, we have detected more than 120.000 attacks of this botnet! The Behaviour of the “Hello, Peppa!” Botnet The specialty of this botnet is that the die ("Hello,...

WordPress hosting and the BitNinja WAF - How to do it right? (Part 3 - The BitNinja safe minimum ruleset)

In the preceding articles, I’ve talked a lot about the BitNinja safe minimum ruleset template and how you should enable it on your “/” location (or on “*/wp-admin/*” if needed) if you’re hosting mainly Wordpress websites. So I’d like to give you a little more explanation about the rules that are part of the safe minimum. There are currently 15 rules from the OWASP Core Ruleset in the BitNinja safe minimum ruleset template, after thorough testing and evaluation. These are part of the following categories: Scanner Detection (1 / 5) Protocol Attack (4 / 10) Local File Inclusion (2 /...

Journey through Europe with a Trabant-Ninjas are breaking the record

Laszlo Takacs
We are checking in with an unusual article. We would like to share an upcoming story about a great Journey, which will start on 28th of July. Why is it worth mentioning? Well, one member of this great Adventure is one of our Ninjas, and we’re really proud of him. They will travel around Northern Europe with a Trabant 601 car in 30 days. Breaking the record No one in this world has traveled this distance (7000KM = 4 349.59 miles ) with a Trabant (which only has a 2-stroke engine). This car sooner or later will be counted as a veteran. The adventure has a charity aspect as well, w...

Attack Vector Miner – AI Technology for Detecting Zero-Day Attacks

Artificial Intelligence (AI) is spreading quickly in many industries, and we can gladly announce the Attack Vector Miner, one of our latest developments based on AI. But before we tell you more about that, let’s get a bit more familiar with AI. If you’re an AI expert, know everything about it, and are only curious about the Attack Vector Miner, just scroll down to the last paragraph. History of AI It’s not a new thing that machines “stole” people’s jobs; let’s think about the steam engine, the calculator, or the PC. But trends today show that we’d like to delegate even more tasks to mach...

WordPress hosting and the BitNinja WAF: How to do it right? - (Part 2)

Last time we finished off with the advice that if you’re hosting mainly WordPress websites, you should only enable the BitNinja Safe Minimum ruleset for the “/” location or any other domain pattern that contains “/wp-admin”. So let’s talk a bit more about domain patterns With the BitNinja WAF, we’d like to give you the opportunity to customize your firewall rules with domain patterns (we also call them location patterns, because they are, in fact, nginx location patterns or directives). It’s similar to virtual hosts defined on a web server. Let’s say that you have multiple domains on...

New LogAnalysis with 109x speed

New LogAnalysis with 109x speed The former version of SenseLog (which serves our robust LogAnalysis module) has processed the files at the start and observed them if there were any changes in them. It has used a lot of sources for the dates in the log rows. In this version it was necessary because SenseLog had to recognize the changes and had to decide whether it has to to something or not with the changes. The process of log files took longer time because of this. The current version only processing the changes, in the case of delegated logs, SenseLog stands at the end. This way therer...
