Sometimes visual programs can’t help us. For istance, let’s assume you would like to extract multiple zip files protected with a common password. How can you do that using a desktop environment, or more in general, visual programs? That’s simple, you can’t do that. Fortunately, shell is our friend, so you can use 7z command to extract your zip files.
First thing, install 7z using apt or yum, depending on your Linux distribution, then run the following command within the directory containing your zip-protected files.
~$ for z in *.zip; do 7z x -pPASSWORD -y "$z"; done
In the last few days you likely received a mail from @outlook.com or @hotmail.com domain accounts saying “XXXXXXXXX is one of your password” and asking you for an amount of Bitcoin (BTC) to avoid revealing videos while you watch adult/sex vids.
Well, that’s clearly fake. Your password has been probably taken from a public data breach (e.g., LinkedIn Data Breach). So, the main cyber-criminal ‘s scope is to scare you, so that you are encouraged to pay the requested amount of money.
Of course, don’t send any money to that BTC account. Instead, consider to change all your passwords.
You can verify if your account has been previously hacked on the following web site: haveibeenpwned.com
Below the text of two mails.
I know xxxxxxxxxxx is your pass. Lets get directly to point. You may not know me and you're probably thinking why you are getting this email? No person has paid me to investigate about you.
In fact, I setup a malware on the X vids (porno) web-site and you know what, you visited this website to have fun (you know what I mean). While you were watching video clips, your browser started functioning as a RDP with a key logger which provided me with access to your screen as well as web cam. Just after that, my software program collected every one of your contacts from your Messenger, social networks, as well as e-mailaccount. And then I made a double video. First part displays the video you were viewing (you've got a nice taste hehe), and next part displays the recording of your cam, yeah it is you.
There are two different choices. Let us explore these possibilities in details:
Very first choice is to dismiss this e-mail. Then, I will send out your actual video clip to each of your your personal contacts and consider about the disgrace you feel. And consequently should you be in a relationship, precisely how it will eventually affect?
2nd option will be to give me $7000. Lets refer to it as a donation. In this scenario, I will straightaway remove your video recording. You can go on daily life like this never happened and you will not ever hear back again from me.
You'll make the payment through Bitcoin (if you don't know this, search "how to buy bitcoin" in Google search engine).

In case you are curious about going to the cop, surely, this e-mail can not be traced back to me. I have dealt with my actions. I am also not trying to ask you for money very much, I just want to be rewarded. You now have one day in order to pay. I have a special pixel in this e mail, and right now I know that you have read this message. If I do not receive the BitCoins, I will, no doubt send out your video to all of your contacts including relatives, coworkers, and so forth. Having said that, if I receive the payment, I'll destroy the recording right away. If you want to have proof, reply with Yes & I definitely will send your video to your 13 friends. It is a nonnegotiable offer and so please do not waste mine time and yours by replying to this email message.
xxxxxxxxxxx one of your password. Lets get straight to the point. No one has compensated me to check about you. You do not know me and you are probably wondering why you are getting this email?
Let me tell you, I actually setup a malware on the adult vids (sexually graphic) web site and do you know what, you visited this website to experience fun (you know what I mean). When you were viewing video clips, your web browser started out working as a Remote Desktop that has a key logger which provided me with access to your screen as well as cam. after that, my software collected your complete contacts from your Messenger, social networks, as well as e-mail . Next I made a double video. First part displays the video you were viewing (you have a good taste rofl), and 2nd part shows the recording of your cam, yea it is u.
There are two choices. Lets read these options in details:
First alternative is to ignore this e mail. In this scenario, I am going to send your video recording to each one of your contacts and just imagine concerning the embarrassment you will see. Not to forget should you be in a loving relationship, exactly how this will affect?
Second option is to compensate me 3000 USD. We will regard it as a donation. In this instance, I will promptly delete your videotape. You will keep on everyday life like this never took place and you will not ever hear back again from me.
You will make the payment via Bitcoin (if you don't know this, search for "how to buy bitcoin" in Google).
In case you are making plans for going to the law enforcement, very well, this e mail cannot be traced back to me. I have covered my actions. I am also not attempting to ask you for money a lot, I only want to be paid for. I've a specific pixel within this message, and right now I know that you have read this e-mail. You have one day in order to make the payment. If I don't get the BitCoins, I will send out your video recording to all of your contacts including relatives, coworkers, and many others. However, if I receive the payment, I'll erase the recording immidiately. If you want to have evidence, reply with Yes! & I definitely will send out your video to your 14 friends. This is the non-negotiable offer and thus please do not waste mine time and yours by responding to this e mail.
In this post we will see how to break V1 password hashes. First of all, download hashcat and search for good dictionaries (weakpass is an awesome resource… ssssh!). Then, before starting with the cracking process, look at mask attack documentation to better understand all charsets used in hashcat.
Good, now you are ready to start…
