Encryptions And Decryption

-

it is a way of secure the data. It’s based on two-way mechanism. if we want, we can encrypt (convert to unreadable format from original data) the data also decrypt(convert to original data from unreadable format) the data and get the original data by using the key. this is based on public key info structure (PIK). Also, it has two type, those are symmetric and asymmetric.

·       Symmetric
We use a single key for encrypting and decrypting in Symmetric encryption.

·       Asymmetric
It has two keys, one is public key other one is a private key. However, we called as the key pair for those keys. We can use both keys to encrypt or decrypt the data. But there is one condition if we use the public key to encrypt the data. We should use a private key to decrypt otherwise we can not recover the original data.

Install android studio on the parrot os

parrot OS is based on Linux environment so we have to download Linux version of android studio. if you want Linux version android studio just click here . after the download is completed you will get the zip file of the android studio. so you need to unzip it first. then you can see several files within the unzipped folder. figure 1 represents the sample output. Figure 1 then go to bin folder which is stored in the unzipped folder. after opening the bin folder, you can see studio.sh shell script. if you execute that, the android studio will be running on your PC's.  Note:- you have to give execute permission to studio.sh for the current user before you execute studio.sh script. (sudo chmod u+x studio.sh) Figure 2 but we will be doing like this. it's annoying, so now we are going to the terminal command that is helped to us to access android studio by using terminal commands.  move your unzipped file to "/root" from Downloads. then go to "/usr

How to do simple brute force attack with burp suite

What is brute force attack? brute force is a kind of password based attack. normally attacker checks each and every possible combination until reaching the expected output. so an attacker should check the huge amount of data but the normal human cannot do this kind of things. that's why we must move on some predefine tools to do this kind of attacks. work through this is the sample login page. we are going to attack this page and get the login credentials.(note: this is a basic login form it does not have any prevention mechanism for brute force attack.) let's try any value on this form and capture the data packet for analyzing. after analyzed we can say these data packets have username and password, which we entered previously. so we have to forward this data packet to intruder tab (right click and select intruder option). now  go to the intruder and mark the target variables which are carrying username and password. The below figure shows that. Note:

PoC video of How to Hack Gmail and Bitcoin Wallet using SS7 flaw

-

A long time ago we published a report about how someone can hack WhatsApp with the SS7 by default. The standard SS7 exists for eons now with corrections, but GSM and telecom companies do not bother or trouble to repair their infrastructure against the standard. Now a Cyber ​​Security Company called Positive Technologies has released a video detail as anyone in any Gmail account can hack with a name and a phone number with the standard SS7. After the abduction of the Gmail account of the victim, the investigators then tried to steal a Bitcoin wallet with the same SS7 defect. Positive researchers sent their video to Thomas Fox-Brewster, an investigating reporter for Forbes, as well as details about hacking. What is the SS7 error? The vulnerability is found in the signaling system 7 or SS7, the technology used by telecommunication operators where the high-security message system and telephone calls depend. SS7 is a set of telephone signaling protocols developed in 1975 that make i
