VSFTPD v2.3.4 Exploit | Backdoor Command Execution | CVE-2011-2523

This is an exploit recorded back in 2011 that took advantage of Unix/Linux users. There was a vulnerability in the FTP server. The vulnerability was in the download of the VSFTPD version 2.3.4 from a website that has long since been taken down.

Hackers were able to login to the server using a smiley face, colon and a closing parentheses, :). The attacker could switch the default FTP port, 21, to port 6200 and establish a backdoor connection. The video showing a demonstration of the exploit using Metasploit and NetCat is on Patreon.

My recommended products (so far) that I use as a lone wolf operator:

CyberGhost - I had no problems with this VPN and highly recommend.
They are based in Romania where the laws on privacy are not so strict.
Not truely anonymous but good for privacy.

KeePass - Excellent offline password manager that I recommend rather
than using a cloud service. https://keepass.info/
