Way of Hashing

-

Hashing is a way of securing our data. Hashing is not used for reusable data, since the feature of backing up original data is not present in the mechanism of Hashing. At current, Hashing has become a way to restore passwords into the database. This is done by the user registering into a system using password and the password will be converted to an other value and will be stored in the database. However, Hashing is not advised for storing data, since Hashing works be randomizing and not ordering data. Hash value is one of the main features for not retrieval data. For example when a password is used on a system, it will be stored under Hash value. When a password is given in a system under the Hash value the system is likely to save the password and make the login time quick. For this to happen the old Hash value and new Hash value has to be matched, if they are not matched the log in will be failed and only if Hash value matches the log in will be successful.


  • ·         Hash collision

Sometime two different input gets same hash value it’s called as hash collision.



  • ·       Salted Hash

Sometimes two users have same password use on same system. if one user is an attacker and if he is going to attack the system. he can get the real value of the other user password. So this situation is threat for other user. System gets password from user also add some random value with password after that hash the password and store. It’s called as salted hash Now attacker can not find any users password.

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
