Sometimes there is a need to steal certain data. And these are not only passwords and logins from social network accounts. There is a possibility of losing data from your credit card, from which your money is subsequently withdrawn. In simple terms, a person who is in no way related to the key data steals them and uses them for their needs.
Compromise Details
You probably did not like the description above, and you want to know in more detail what compromise is. Now we will move on to this. At its core, this is the usual theft of data for the purpose of its further use, when an unknown person gains access to secret keys.
What is cryptography compromise
Often, attackers need some time to compromise, so the system will recognize them and block access. Often, the compromise of cryptography is considered as the ability to access a private key, algorithm, account, or any other security elements that allow you to confirm the identity of the user during the exchange of information.
How is data theft carried out?
In methods, hackers are very diverse, information can be obtained from open sources. For example, you accidentally took a photo on which you can see the password sheet from the social network. This is perhaps a commonplace case, but it also has a place to be. The user may lose the storage medium, they can connect to his device through special programs.
Credit Card Theft
And with bank cards, they do more: sophisticated, an advertisement is displayed to the user, where they are offered a unique product at a special price. Naturally, you need to enter data from the card and the code located on the back side. Be careful, never give your CCV code to unauthorized persons and unfamiliar sites!
Shimming is also used - this is a more advanced skimming. If in the second case a bulky device was installed on the ATM to read information from the card, which could be noticed, then when shimming it would be impossible to do this without devices.
Protection methods
First, learn computer literacy. This means that you should be aware that the Internet is not a place to store critical files. And if there is an opportunity, you will always be stolen by bank card information or other valuable types of information.
The situation with secret keys is similar. The more they are used, the greater the chance to compromise them and take advantage of them. The danger increases when using the same key for a long time.
