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 […]
