Everyone cares about their significant others' security. We all know that feeling when your calls are not answered and your Whatsapp messages not marked as read. In a moment like that you would do a lot to have any idea what is happening there. Although cell phone carriers offer geolocation services to locate another user, knowing your girlfriend is somewhere in the middle of Main Street will barely help. So what can we do about it?

Since its rise Windows was a natural habitat for all kinds of malware. Now the OS itself seems to have become one big trojan. Right after being installed it starts acting weird. The data flows in rivers to dozens of servers belonging to Microsoft and its partner companies. We will try to look into complaints of espionage manners of Windows 10 and find out what data it sneaks and where it sends it.

This was one of the most interesting attacks showed on Black Hat Las Vegas 2015. Let’s imagine the situation: there’s a large park of Windows computers in a large organization, and they all need to be updated. Obviously, getting all of them to download updates over the Internet is both pricy and uncomfortable. The common solution is a WSUS (Windows Server Update Services) server, which is used to manage updates. It downloads the updates and delivers them to all other computers.

Before turning to unconventional methods of usage, I will describe how “keep-alive” is working. The process is utterly simple – in a connection, multiple requests are sent instead of just one, and multiple responses come from the server. The benefits are obvious: there is less time spent on establishing connection, less load on CPU and memory. The number of requests in a single connection is usually limited by settings of the server (in most cases, there are at least several dozen). The procedure for establishing a connection is universal.

We will start with a definition. MySQL is a relational database management system with different data storage engines, such as MyISAM, InnoDB, Archive and others. Like most open source projects, it has its own branches, for example, MariaDB. Before going into details, I would like to mention that most of discussed vectors/techniques/bugs apply to various engines and branches, though not always.

Well, how could we ‘boost’ privileges on Windows? First of all, we should say that there were found, lately, a lot of vulnerabilities regarding fonts parsing which make the process of privileges elevation rather simple as long as we have a proper exploit. If you use the Metasploit then you need only one command to get the system shell. However, it will only work if the system is not fully patched. In case if the machine has all the updates installed, despite the Linux, we will not be able to find SUID-binaries in here, furthermore the environmental variables usually do not transmitted to services or processes with higher privileges. So, what we can do then?

I guess you have heard about Evilgrade framework that allows to “fix” the update mechanism of the most popular programs (Windows update, Apple update and so on and so forth) by replacing valid files with malicious ones. You probably think that only the application’s updates are vulnerable? Well, you are wrong. I shall be honest with you, it is not that secure to download files from the web as it might be seemed from the first sight. Don’t believe me? Then look, or better say, read.
