Classification of malware

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 many ways in which malware can be categorized, but now we’d like to introduce Christopher C. Elisan's classifications from his book, Malware, Rootkits & Botnets. 1.Infectors Infectors have a very important limitation: they can only sprea...

IT security misbeliefs – third IT security meetup by BitNinja

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. Not only did the cold beer and the delicious pizza attract participants, but so did the interesting topics we were discussing. The most recent topic was: IT security misbeliefs. 1.“If I’m using a strong password, everything is OK.” Most people believe that if they have a...

The Most Famous Vulnerabilities: SQL injection

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 blog series started—because there are some vulnerabilities we need to talk about. The first patient is SQL injection. My previous blog article which was about the Hackerone also encouraged me to make this blog series. On this platform, there is a lot of public report for SQL injection...

HackerOne – The Biggest Bug Bounty Platform

HackerOne – The Biggest Bug Bounty Platform

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 sue? The same fear is present on the other side. As a software or IT company, we were worried about the agreement of the external penetration tester because we were afraid that the related information would come to a bad man. Fortunately, nowadays bug bounty platforms solve these problems. One of the b...

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 /...
