Anyone with physical access to the host eventually will be able to get at your system and change it arbitrarily - including the ability to change the password. In the special case of a virtual machine, this would be even easier as anyone with control over the hypervisor could modify the vCPUs behavior and read the guests' memory.

In other words: in a VM you have no other choice but to trust your hoster is not doing any of these things. One thing to keep in mind with any and all security concerns is that hardware access trumps anything you can do. If you have access to the physical server, you are the beginning and end of the security for that server. No matter what you do on your VPS, the owner of the machine has the last say when it comes to security.

This doesn't mean that you should worry about them accessing your machines, because in all likely-hood no-one will even try to access your machines. But if you want a definitive answer: yes they can reach your VPS.

Encryption won't help. The VPS has to get the key from somewhere, the provider could get it from the same location. Besides the key would have to be in memory while the file system is mounted, the provider can copy anything inside memory of a VPS.

However, I think that accessing an encrypted image is more difficult than just loopback-mounting an image file with kpartx. Yes it takes a little bit more than just mounting the disk image. But it's not much more than that, especially with actual forensic tools. I've used a program that you literally point at the disk image and the memory dump, it does the rest for BitLocker or TruCrypt. The Overflow Blog.

If i have vps on some remote provider, operator like amazon or aruba etc, and on ubuntu there, i have directory encrypted but mounted as decrypted, for example through encfs. Boot, login to shell, mount with password, logoff and leave running. And this mounted folder,directory is shared to me through nginx or ftp server so i have access to it remotely without needing to decrypt.

But since it is decrypted on this remote vps, and key is in vps machine memory, how can i protect it if vps company, aruba or amazon employee would like to sniff into it? There's no technological way for you to ensure no-one having physical access to the server can't access your data, as he would posses both the encrypted data and the key. You have to trust your service provider on this. If the service provider as a company is not trustworthy, don't give your data to them, encrypted or not!

For individual employees the could companies have strict policies, background checks and audit methods. A company this big can't afford losing the customer trust.

All requests are reviewed and approved by the appropriate owner or manager. If you have something so sensitive that this isn't enough, only store this data by yourself.

And if it's tin foil hat level sensitive, don't have this machine on the Internet, either. This is something you actually should be worried about! Sign up to join this community.

During penetration testing, sometimes you get stuck with a secure environment where all the servers and end-clients are fully patched, updated, firewalled, and have anti-virus software installed.

Network firewall rules have been configured properly, and all internal clients are NATed to the Internet. Pen-Testing Training. In such a situation, client-side attack and having knowledge in programming are your best friends. Why is that? For example, no matter what your security rules are, if you can trick the right person into opening the wrong malicious software, the system may get compromised.

At the final stage we will export this backdoor as a standalone and test it against online virus scanners as well as inside a simulated secure environment in VirtualBox. Why Python? You will have a great example of forging Python in penetration testing and you may use or tune the code for a real world case. Plus you will be aware of the effectiveness of client-side attack and the importance of programming your own weapon where other tools will fail in such a tough scenario.

Building the machines from scratch inside VBox is out of our scope in this article; however, I have to briefly show you the configuration in case someone would like to replicate the scenario. Pfsense configuration.

In this case, I assumed 80, and 22 will be allowed. There are too many ways to do this; during reconnaissance phase, you may search around and see what topics this employee is interested in.

Get my point here? I will leave this to your imagination, as every penetration tester has his own way. Inside this secure channel, we will transfer arbitrary commands to our victim and make it send the execution result back to us. Python has many third-party libraries that simplify SSH implementation and provide a high user level. I will use the Paramiko library, as it has fabulous features and allows us to program a simple client-server channel and much more!

Files we are interested in:. Server Side. The code starts with defining the location for RSA key, which be used to sign and verify.Such as the version number for example which could not be retrieved with Nmap. From the Metasploitable enumeration tutorial we got the following information from Nmap:. For instance a version number.

Click the add button and name the new network Metasploitable Click on the add button to add a new network and name it Metasploitable 2. Next click on the Edit button and enter the Metasploitable 2 IP address for the new network and use port as following:. Click edit to specify the IP and port divided by a slash sign.

Close the windows and click on the connect button to connect to the IRC service on Metasploitable 2. A lot of information is presented to us when we enter the IRC channel. The hostname, some configuration information and what we were looking for: the version number of the Unreal IRC service. As you can see the version is Unreal 3.

We can use this information to perform a vulnerability assessment and see how we can exploit this service. We will be exploiting the Unreal IRCd service in this hacking tutorial using the Perl script and the Metasploit module. Before we launch any scripts and exploits we need to analyse the code and see what it exactly does.

The first three lines set the value of 3 variables named host, port and type to nothing. Then they are assigned with the values from the first three arguments; the host, the port and the type. The 3 lines to follow test the 3 variables for null values and execute the usage function when a null value is found on 1 of the variables.

This will exit script execution since the usage function ends with exit 1.

In the usage instructions we can see that 5 different types can be used to launch this exploit. When we look at the options carefully we can see that type 2 and 3 have been switched in the code:. In the next code block we can see that the selected type number matches the payload number on execution. Type 1 executes payload 1, type 2 executes payload 2 etc.

Very strange but a great example teaching us why we need to analyse the source code before compiling and launching exploits. The following video demonstrates each step in hacking unreal IRCd 3.

Since we have no control over the downloaded file and we do not know the contents of this file, we will modify the exploit to get control over the payloads. We will be performing the following steps:. One major downside of the current Perl script is that it depends on wget for successful exploit execution.

The exploit would fail if wget is not present on the target host. This is often not the case but we will be removing this dependency by initiating a Perl reverse shell directly from the command line instead of a file.

Generate a Perl reverse shell using msfvenom. We can test the payload by issuing the msfvenom output to the command line and open a netcat listener on our attack box:.

Reverse shell is working from and to the attack box. You can see that we got a connection from our own attack box to the attack box since the connect to and from IP addresses are exactly the same. Now we know that the reverse shell payload from msfvenom is working we can copy the Perl exploit script to our desktop with the following command:.Zach DeMeyer. October 19, Read this guide to keep employees secure and productive wherever they work. By tinkering with the unique Relative Identifier RID associated with every Windows account, anyone can update their account to have nearly ultimate power in an IT organization.

For your average employee, having admin access carries little weight. Sure, maybe one can use their newfound admin abilities to turn off the pesky privacy features that their IT admin installed on their system. But, petty office pranks aside, unrelinquished admin access is nothing but trouble.

An employee with unauthorized admin privileges and an ounce of malcontent is a dire threat to any organization. The same could be said for a hacker exploiting this backdoor from the outside. The consequences are grave, to say the least. Here at JumpCloud, we believe that this sort of vulnerability compromises the very core tenets of IT practice. With Directory-as-a-Service, admins can strongly control the authorization of access to user accounts via a secure, remote admin console in the cloud.

That last sentence may have set off alarm bells in the minds of some, and for good reason. Anything installed should be able to be uninstalled, right?

In their tests, Coalfire found that the JumpCloud Agent could not be uninstalled by the user. Add on top of that enforceable password complexity requirements, multi-factor authentication, and more, and your JumpCloud identities, admin or not, are made hypersecure.

Linux is known for having a great number of mature, useful command line utilities available out of the box in most distributions. Skilled system administrators can do much of their work using the built-in tools without having to install additional software.

In this guide, we will discuss how to use the netcat utility. Often referred to as a Swiss army knife of networking tools, this versatile command can assist you in monitoring, testing, and sending data across network connections. We will be exploring this on an Ubuntu Ubuntu ships with the BSD variant of netcat, and this is what we will be using in this guide.

Other versions may operate differently or provide other options. This will attempt to initiate a TCP to the defined host on the port number specified. This is basically functions similarly to the old Linux telnet command.

Keep in mind that your connection is entirely unencrypted. On most systems, we can use either netcat or nc interchangeably. They are aliases for the same command. Although netcat is probably not the most sophisticated tool for the job nmap is a better choice in most casesit can perform simple port scans to easily identify open ports. We do this by specifying a range of ports to scan, as we did above, along with the -z option to perform a scan instead of attempting to initiate a connection.

Along with the -z option, we have also specified the -v option to tell netcat to provide more verbose information. As you can see, this provides a lot of information and will tell you for each port whether a scan was successful or not. However, your scan will go much faster if you know the IP address that you need. We can send the standard error messages to standard out, which will allow us to filter the results easier. We will then filter the results with grep :. Here, we can see that the only port open in the range of on the remote computer is port 22, the traditional SSH port.

It also can listen on a port for connections and packets. This gives us the opportunity to connect two instances of netcat in a client-server relationship. Which computer is the server and which is the client is only a relevant distinction during the initial configuration.
