Installing
Jul 15, 2014 ClamXav is a free antivirus solution based on the Open Source engine, ClamAV. Even though Mac OS X is considered a secure operating system from the viruses that actively attack the system point of view, the users shouldn't enjoy the 'status quo'. The thing is, there are certain situations when a Windows virus can attack a Mac. ClamAV ® is the open source standard for mail gateway scanning software. High Performance ClamAV includes a multi-threaded scanner daemon, command line utilities for on demand file scanning and automatic signature updates. ClamAV is an open-source anti-virus software that supports multiple files and multiple signature languages. It automatically detects malware, Trojans, viruses, and any other online activities that can cause damage to your database and system in the early stage. Offline update for systems with no direct internet access. Update Signature Database with clamav-freshclam. If you have internet access, you can use clamav-freshclam to update the ClamAV virus signature database. To use this method, stop the clamav-freshclam service (if it is running) and execute freshclam, the virus database update tool. +1 I found this answer to work - and to actually install clamav-daemon as this answer suggests, use: apt-get install clamav-daemon or sudo apt-get install clamav-daemon (if non-root user with sudo-er privileges) I did this after running sudo apt-get install clamav – therobyouknow Aug 7 '16 at 9:56.
ClamAV can be found for Ubuntu in the apt repository. Run this command to install ClamAV:
apt-get install clamav
If you need clamd, you may also want to run:
apt-get install clamav-daemon
If you require support for scanning compressed RAR files you first need to enable the non-free archive, and then you can install the RAR-plugin using:
apt-get install libclamunrar6
Clamav No Machine
There are two classes of clamav packages available for Ubuntu users:
Released Set
The released set (release, *-updates, and *-security) are patched for security updates. Following extensive testing of clamav and the packages that use it in the backports repository, they may be updated to a newer version. These are official Ubuntu packages and supported by community developers.
Backports
The Ubuntu backports repository will contain the newest clamav version that has been at least lightly tested to work with that version. These packages can be installed by enabling the backports repository on your system.
Ubuntu packages are maintained by Ubuntu MOTU Developers.
ClamAV is a machine available in the Practice area of the Offensive Security Proving Grounds. This box difficulty is easy. Lets dive in and take a look.
Starting with a nmap scan enabling all scripts, detecting versions, and output all formats to files starting with the string “simple”.
So using this nmap scan and a quick search based on the name of the box we see a few possible exploits.
From the list showing “clamav” exploits we see one that is targeting SMTP which we know is open from the nmap scan.
Lets take a look at the pearl script.
So it looks like the exploit will be opening a new port 31337 and running sh as root. Lets take a look at the current status of the port.

Port 31337 is closed as expected. Running the exploit.
Clamav Windows
No errors with execution and the message looks to be accepted for delivery. Looking back at the port, its now open!
Clamav Download For Windows 10
Netcat to the port.
Wow, root immediately.
“bash -i” to upgrade the shell just a bit. Navigate to the root desktop to grab the proof.txt.
How Good Is Clamav
ClamAV is a fun one, but the machine name gave a huge advantage to the attacker. The Offensive Security community claims that ClamAV is a retired OSCP exam box. So it was good practice if nothing else. Until next time, stay safe in the Trenches of IT!
