Dear Bleeping computers folks. You helped me a while back with combofix and solving problems on my computers which were generated by a renter on my network. Many thanks for that. I would like some assistance on a new topic. Thanks in advance
I have done research on the internet and been on Bleeping Computer to see if I could find an answer to this problem. I have been online trying to find an answer to this problem. It is hard for me to find and answer to this. If you can help me that would be great .
My question is related a renter,
He has a Linux operating system on his computer as well as windows. I understand that Linux is a very efficient way of hacking and that there are programs such as John the Ripper which make it easy for Linux users to compromise computers and networks.
Last Sunday he downloaded some form of malware that made it impossible for him to connect to a java download site. It disabled his net phone from connecting also. It also made my laptop and a desktop inoperable in downloading from this site.
He came out several hours later and said that he removed the virus from his computer and that he could now download java. Something did not feel right to me.
I went onto both my desktop and my laptop. With out running anti-virus or malware bytes on my laptop or desktop, I could immediately connect to the java download site.
I have two sons that have shared the network with me for ten years. At time we have all had malware and pups on our computers. We have never transferred them from one computer to another computer. Ever.
My concern is that the renter has used Linux to compromise my computers and the network. That he has some how assigned himself administrative privileges over the network and its computers with his knowledge of Linux.
How is it possible that he deletes malware from his computers and that I can then get to a web site and download from it when I was blocked from it prior to his removing it from his computer. After he removes the malware from his computer, I can get to the website from which I was previously blocked. As noted i did not run malwarebytes, which i have or avast virus scans before I connected to that site from which his virus was blocking me.
How likely is it that he has used Linux to compromise my computers? I had this problem several years ago when I rented to a person who considered himself a hacker and he was. I found some of my data on his computer when he was showing my some stuff on his computer.
If there is any light you can shed on this, I would greatly appreciate your help.
