» SHA-2 (“Secure Hash Algorithm 2” – 2001): it’s a safer variant of SHA-1, with bigger hash dimensions, from 256 (64 hexadecimals) to 512bit (128 hexadecimals). Not considered safe anymore, after Google showed the possibility for collision. » SHA-1 (“Secure Hash Algorithm 1” – 1995): it generates a 160bit fingerprint (40 hexadecimals). Developed by Ronald Rivest, it is by now not considered safe anymore. » MD5 (“Message Digest” – 1991): it generates a 128bit fingerprint (32 hexadecimal alphanumeric symbols). This is a substantial difference compared to encryption algorithms (AES, RSA, etc.), which instead are reversible if you know the key (password). The characteristic of Hash is that of being one way, meaning non-reversible: from the hash it is not possible to get back to the initial value. The binary string is then converted and represented in hexadecimal (hence its length is reduced four times). HASH are encryption algorithms that turn an arbitrarily long datum (message) into a binary string (fingerprint) of fixed length (a length which varies depending on the algorithm used). To do this, it is important to know what Hash are and how they are used to manage passwords.

Let’s now examine how passwords are managed, with the aim of understanding the way in which password cracking techniques work.

And if they must all be different, this cannot be done only through mnemonical rules. The problem of keeping one’s credentials safe is becoming quite complicated: it is well-known that each user must manage around 100 passwords. Passwords are the “keys” of our digital life: according to the Verizon Data Breach Investigation Report 2017 (VDBIR 10th edition), “81% of account breaches are realized through stolen and/or weak passwords”.

It should not be necessary to stress again how today it has become important to protect one’s passwords: by now, it should be considered an elementary “cyber hygiene” norm – for all users of computers and of the web. They are so-called “low intensity” attacks, which make no sound, hence they do not generate any kind of alarm in the attacked system (because they are not repetitive, like instead are “brute force” attacks).īut, since the terrible habit of using the same password on different services is so widespread (as reminded earlier for Zuckenber and not only him …), this attack has a great chance of success. In this way, it is possible to try the same combinations of username and password on websites and services that have not been hacked yet.

This mine of information is used by cybercriminals to attack other web services where the users have re-used the same passwords.Īnd all this is carried out in a totally automated manner, using a software like SHARD (which is open source and available on GitHub). The technique used is indeed credential stuffing, a practice that exploits the enormous quantity of data breaches that have taken place over the years and that have generated many databases of stolen credentials, easy to find on the dark web. The LinkedIn case is famous: around 164 million credentials were stolen (this happened in 2012 but the passwords were put up for sale in 2016), among these there was also the one of Mark Zuckerberg, who used the same password for LinkedIn (which was “dadada”) also for his Twitter and Pinterest accounts.

» Credential stuffing: a service database that contains a great number of user passwords is hacked and the passwords are tried on other websites. » Social engineering: through emails or phishing messages the user is convinced to communicate his own password. We will point out here the two techniques that are most frequently used to obtain – with minimum effort – a password that is not adequately guarded. There are different ways, but in most of the cases they act on human error. How can cybercriminals steal our passwords?
