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...

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 /...

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...
