As a member of the BitNinja Development Team, one of our most important tasks is to develop the protection of BitNinja. When we deal with such a process we can see how an attack works or how a botnet can exploit a vulnerability. It's almost like watching these events behind the scenes. That's why this […]

Our world would be insecure without bug bounty platforms. We don’t know who we can or cannot trust. If we find a vulnerability in a software as a white hat hacker, we would be afraid to report it to the software owners because we wouldn’t know what their reaction would be. Will they reward or […]

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 […]

In a previous article, we’ve discussed the BitNinja safe minimum ruleset for the BitNinja WAF, that consists of 15 rules from the OWASP Core Ruleset, along with 6 rules from the BitNinja rules category. These rules can be safely enabled on the root location pattern on your server. In the BitNinja Ruleset, there are 5 […]

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 […]

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 […]

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 […]

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 […]

Understanding CVE-2026-5629 and Its Implications for Server Security Recently, the CVE-2026-5629 vulnerability was identified in Belkin's F9K1015 router model. This security flaw arises from a buffer overflow in the formSetFirewall function within the device's firmware. The vulnerability allows malicious actors to exploit the device remotely, which poses a significant risk for system administrators and hosting […]
