	"plain_text": "Massive breach leaks 773 million email addresses, 21 million\r\npasswords\r\nBy Alfred Ng\r\nPublished: 2019-01-17 · Archived: 2026-04-06 01:16:31 UTC\r\nThe best time to stop reusing old passwords was 10 years ago. The second best time is now.\r\nAlfred Ng Senior Reporter / CNET News\r\nAlfred Ng was a senior reporter for CNET News. He was raised in Brooklyn and previously worked on the New\r\nYork Daily News's social media and breaking news teams.\r\n2 min read\r\nIn one of the largest public data breaches, a collection containing more than 87 gigabytes of personal information\r\nwas leaked online.\r\nThe data dump, titled \"Collection #1,\" was hosted on the cloud service Mega, and had 772,904,991 email\r\naddresses, and 21,222,975 passwords. The treasure trove of private information was discovered by Troy Hunt, a\r\nsecurity researcher and founder of the \"Have I Been Pwned\" service.\r\nThe login credentials appear to have been stockpiled over years, as some passwords and emails come from 2008,\r\nHunt said on his blog. The information comes from more than 2,000 different sources, Hunt said. You can check if\r\nyou were affected by the breach by entering your email address on Have I Been Pwned. And you can see if\r\nindividual passwords were compromised by clicking here. \r\nBreaches continue to happen on a massive scale as companies collect data on millions of people and fail to protect\r\nthem properly. Marriott experienced one of the largest personal data breaches in history, losing personal\r\ninformation belonging to 383 million guests, while hackers hit Yahoo and stole data belonging to 3 billion\r\naccounts. The big numbers don't always equate to dire after-effects; the breach of Yahoo accounts, for instance,\r\nisn't likely to have the same potential for damage as the compromising of 147.7 million Social Security numbers\r\ntaken in the Equifax breach.  \r\nhttps://www.cnet.com/news/massive-breach-leaks-773-million-emails-21-million-passwords/\r\nPage 1 of 3\n\nWatch this: Biggest hacks of 2018\r\n 03:25\r\nBut just because your information is stolen doesn't mean that you're helpless.You can, and should, change your\r\npasswords.\r\nWhen potential hackers have access to this massive amount of login data, they're not sitting at a computer trying\r\nto log into every account one by one. They're using bots to do it through a technique called credential stuffing,\r\nwhich automatically blasts multiple services with the same set of login information.\r\n\"Massive data breaches like Collection #1 create huge spikes in bot traffic on the login screens of websites, as\r\nhackers cycle through enormous lists of stolen passwords,\" said Rami Essaid, a co-founder at bot security\r\ncompany Distil Networks.\r\nhttps://www.cnet.com/news/massive-breach-leaks-773-million-emails-21-million-passwords/\r\nPage 2 of 3\n\nThe company found that websites experienced three times as many login attempts after public breaches happen.\r\nThe idea is that if you've reused those old passwords for different platforms, a potential hacker would use the\r\nleaked passwords to break into your newer accounts with these bots.\r\nWith this recent leak, it's a reminder for people to change their passwords, or start using a password manager that\r\ncan automatically generate secure passwords for you. \r\nThe best defense...: Data breaches can sucker-punch you. Prepare to fight back.\r\nThat Marriott breach: Hackers stole more than 5 million passport numbers.\r\nSource: https://www.cnet.com/news/massive-breach-leaks-773-million-emails-21-million-passwords/\r\nhttps://www.cnet.com/news/massive-breach-leaks-773-million-emails-21-million-passwords/\r\nPage 3 of 3",
