A few days ago, we released a new agent version (1.23.3), which contains very important developments: We added two new SenseLog rules. The first one detects arbitrary file uploader bots, and the second one is for Joomla Spam regers. SenseLog is prepared for future remote config update. Instant blacklist action added to WAF Manager. It […]

The current world war isn’t happening in the physical world. However, cyber attacks have stepped into the foreground, and blackhat hackers can gain millions with their targeted attacks. Their main weapon in this war: malware. In this article, we’ll diversify the different types of malware so that you can better understand their behaviour. There are […]

We like attending meetups because we believe that great ideas are created when we share our experience and knowledge. That’s why we decided to organize regularly an IT security meetup in our town, Debrecen. On 24th August, we held our third meetup and we are so happy that the number of the attendees is increasing. […]

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 […]

Introduction to CVE-2026-35535 The recent announcement of CVE-2026-35535 highlights a significant privilege escalation vulnerability affecting Sudo, a widely used command-line utility in Linux systems. This flaw allows an unauthorized user to gain elevated privileges, potentially compromising the system’s integrity. As server administrators and hosting providers, understanding this vulnerability is crucial to maintaining robust server security. […]
