    Default ozAudi is being attacked!!

    So, as probably most of you have noticed, ozAudi (and our other sites) has been running slow.

    The good guys at Crazy Domains have put it down to a brute force attack (actually two!) from China and Hong Kong.

    We've now tried to block the attack, so hopefully it will fix the slow/connection issues.

    To give you some idea of how hard we've been hit, here are the stats for this year for ozAudi..

    Interesting. Didn't really consider an attack so that's good to know. The site was really slow this morning so this will help understand the issues.

    Cyber attacks are pretty much common place these days. I recently suffered a ransomware attack, eChOraix. 6TB of storage with the .encrypt extension at the end of every file. Luckily I managed to find a tool to do the decryption but it is still time a consuming exercise to get it all decrypted and all back to normal. I had left a telnet backdoor open so it was entirely my fault.

    No matter whether it is the Ozaudi site or your own personal PC no one is immune from attacks so dont think it may never happen to you because it may. Keep your protection up to date.

    Great advice if only I could translate it. Shows how things move on. Back in the early 80's I built all my own computers, wrote programs, was a "expert" with DOS, OS2 & 3, Windows 2 and now, I can speak more Dutch than I can this language.

    Ransomware is where hackers find a backdoor/weakness into you system and encrypt all your files , making them inaccessible for you to use. Basically if you want the key to unlock them you need to pay the ransom, normally in Bit Coin. There is no guarantee that the hackers will give you a decryption key to unlock your files or a key that will be 100% successful. In my case I was lucky enough to find a decryption tool that some very smart person had written that actually worked. So I now have access to all my files again and have now locked all doors and windows.

    All jokes aside don't have simple passwords, they are easy to break. I now have a combination of 14 digit/character passwords on everything and use 2 factor authentication where ever possible.

    Its a scary world out there....

    I think I'm on top of the threats and issues, haven't been got yet. A past job puts the key issues in focus and things like a separate login password for everything helps a little, albeit more than 100 passwords is a right pain. Some stuff goes on a computer that never sees the net. The technical aspects have moved on past me though. You hear the words but how they function is another thing.

    Is this preventing me attaching Jpegs to threads?

    These sorts of things are very common overall, not just brute force attacks but just typical attacks.

    Somewhat on this topic I honestly suggest for anyone with a PC to consider doing the following (Especially if you are.. using the PC for more then research).

    A. Malwarebytes Free and run once every 2 weeks or so
    B. Bitdefender Paid Anti Virus (Get the free trial and they usually give you a deal)
    C. Being aware when being online and not installing browser extensions, etc
    D. The one exception to this being uBlock Origin (Whitelisting OzAudi of course) or considering a PiHole (more info on that here)

    Lastly NEVER giving someone remote access to your computer unless you've verified who you are speaking to or have made an outbound call to technical support
