Monster breach! The weekteam last time we saw big headlines in the print and online press about a massive data breach.
Yes, someone gathered a very long list of 773 million unique email addresses and 21 million unique passwords. 
But there is no reason to worry.
However, tech news reports with scary headlines: Gizmodo described the leak as "mother of all violations“. Wired referred to it as a "monster breach" and the Daily Mail as the "largest collection of hacked EVER data". Mashable was asking its readers to change their password.
Do not panic! Monster breach? No problem!
If you follow the news on iGuRu.gr you will know that millions are already circulating passwords στο διαδίκτυο. Το 2016, για παράδειγμα αναφέραμε ότι hackers ήθελαν να πωλήσουν 427 εκατομμύρια κωδικούς πρόσβασης του MySpace και 117 εκατομμύρια κωδικούς πρόσβασης του LinkedIn.
This new violation, called "Collection #1," is not as different as other violations of the past. According to Troy Hunt, a security researcher who discovered and analyzed the list, this collection includes 773 million unique e-mail addresses and 21 million unique passwords.
But let's just break the numbers:
This collection also includes older ones data.Of the 773 million unique email addresses, only 141 million (about 18 percent) were not included in I Have Be Pwned, Hunt's database. And of the 22 million passwords, only half were not already in the database.
So what's the risk?
The only real risk to cybersecurity is in the case of credential-stuffing. In these attacks, hackers try every possible combination of emails and passwords from the databases they have in their hands.
So if you use a unique password and two-factor connection, these attacks just will not work.
But the change of habit is difficult. For a change and while it's still early 2019, try something new for your security.
Install a password manager.
It will make your life much easier, since you will not have to remember the codes you use. An app we often recommend on iGuRu.gr is Free Keepass Password Administrator. It saves everything locally (on your system, not the cloud) and with very strong encryption.
So you don't need to panic. View the breach above as an opportunity to upgrade your security. Install an app managementof passwords.
