1
00:00:00,240 --> 00:00:07,279
so there have been plenty of reports in the news lately about large-scale data

2
00:00:05,279 --> 00:00:10,800
breaches caused by everything from clever hacking to poor security

3
00:00:09,120 --> 00:00:15,280
practices to somebody just leaving a flash drive

4
00:00:12,800 --> 00:00:19,920
lying around but once everyone's email addresses passwords and credit card

5
00:00:17,199 --> 00:00:24,240
numbers get stolen what actually happens to all that information i mean is there

6
00:00:21,920 --> 00:00:28,800
just like a walmart for cybercriminals where they go to buy your personal

7
00:00:26,000 --> 00:00:33,120
information at rollback prices and if your information is indeed part of a

8
00:00:30,720 --> 00:00:37,040
massive breach how do you find out what are the appropriate precautions

9
00:00:35,120 --> 00:00:42,000
so one thing that's helpful in understanding what happens after a data

10
00:00:38,960 --> 00:00:44,239
breach is to realize the sheer scope of

11
00:00:42,000 --> 00:00:49,920
many of them it's not uncommon for these breaches to affect tens of millions of

12
00:00:47,280 --> 00:00:55,280
people at once and sometimes even more so that means that it isn't particularly

13
00:00:52,480 --> 00:01:00,480
easy for an individual user to search through large databases of stolen

14
00:00:57,920 --> 00:01:06,320
information especially considering the sorts of places that information ends up

15
00:01:03,440 --> 00:01:11,200
oftentimes this data actually will appear on dark web markets that require

16
00:01:08,799 --> 00:01:14,560
special software to access them where it is indeed

17
00:01:12,400 --> 00:01:19,200
bought and sold by cyber criminals hoping to rack up fraudulent charges

18
00:01:17,200 --> 00:01:23,119
drain someone's bank account or even commit outright identity theft

19
00:01:21,680 --> 00:01:28,320
now you can learn more about the dark web here but it turns out that this isn't

20
00:01:26,320 --> 00:01:34,479
the only place where personal data can appear in fact sometimes it'll show up

21
00:01:30,960 --> 00:01:36,479
in a much more public pastebin site

22
00:01:34,479 --> 00:01:41,520
what's a pastebin site you might ask well it's kind of the digital equivalent

23
00:01:38,880 --> 00:01:46,640
of the inside of a bathroom stall wall they're designed for anyone to just dump

24
00:01:44,560 --> 00:01:51,840
a large amount of data as plain text and these things can be great

25
00:01:49,600 --> 00:01:56,320
for folks like coders who want others to check their code for errors or i mean

26
00:01:53,759 --> 00:02:01,200
just anyone who needs a place to quickly jot down a non-sensitive information

27
00:01:59,040 --> 00:02:06,159
in recent years though some pastebin sites have become hotbeds for stolen

28
00:02:03,520 --> 00:02:11,440
data procured from data breaches now some of this data is put there by

29
00:02:08,560 --> 00:02:16,319
hacktivists who don't seek to make much if any money off of their exploits while

30
00:02:14,000 --> 00:02:21,599
other leaks are partially dumped to pastebin sites by attackers as a free

31
00:02:19,440 --> 00:02:26,560
sample of a larger dataset that they expect to get paid for on one of the

32
00:02:24,080 --> 00:02:30,640
aforementioned darknet markets and while anyone can bring up data

33
00:02:28,720 --> 00:02:33,519
that's dumped to a paste bin it's not exactly easy for the average consumer to

34
00:02:32,800 --> 00:02:38,080
go hunt for their credentials one by one

35
00:02:36,480 --> 00:02:42,000
after they heard about the latest big data breach on the news

36
00:02:39,840 --> 00:02:46,400
there is good news though there are easier ways to keep tabs on your logins

37
00:02:44,239 --> 00:02:51,360
and passwords there are services that try to catalog dark net leaks and that

38
00:02:49,200 --> 00:02:56,720
automatically detect when large data dumps appear on paste bins then organize

39
00:02:54,080 --> 00:03:01,440
them into databases and save them even if the original data gets taken down one

40
00:02:59,360 --> 00:03:05,599
of the best known of these services is have i been pwned which works by having

41
00:03:03,599 --> 00:03:10,239
you enter your email address which it then checks against a database of

42
00:03:07,840 --> 00:03:15,280
billions of leaked account records to see if you've been affected by a breach

43
00:03:12,800 --> 00:03:19,760
have i been pwned uses a bot to monitor pastebin sites for new submissions

44
00:03:17,040 --> 00:03:24,080
containing credentials and passwords it offers email notifications if the site

45
00:03:21,840 --> 00:03:28,560
finds your info in a recent breach and it also allows users to enter their own

46
00:03:26,400 --> 00:03:30,879
passwords to check against the database as well

47
00:03:30,000 --> 00:03:35,519
which sounds like a terrible idea

48
00:03:33,519 --> 00:03:40,080
but don't worry have i been pwned employs an algorithm that keeps your

49
00:03:37,280 --> 00:03:45,040
password secure when you test them by hashing them then only sending the first

50
00:03:42,720 --> 00:03:48,640
five characters of the hash to a server that contains the database of known

51
00:03:47,120 --> 00:03:52,560
breached passwords after any matching hashes are found

52
00:03:50,480 --> 00:03:56,799
they're sent back to your pc which can then determine if your entire hash

53
00:03:54,640 --> 00:04:00,799
password is the same as any of the passwords found in the database if you

54
00:03:59,040 --> 00:04:03,760
don't know what a hash is by the way you can learn all about them

55
00:04:02,480 --> 00:04:07,680
right up here this functionality has actually also

56
00:04:05,599 --> 00:04:10,959
been built into some password managers which can even tell you if your

57
00:04:09,120 --> 00:04:15,760
credentials have been found in a recent data dump so

58
00:04:13,120 --> 00:04:20,720
that's cool but then what if you follow these steps and your details have been

59
00:04:18,000 --> 00:04:25,680
compromised well step one is to change your passwords step two is to contact

60
00:04:23,360 --> 00:04:29,759
your bank and credit card companies if your email was tied to those accounts

61
00:04:27,440 --> 00:04:33,919
and get in touch then with step three one of the major credit reporting

62
00:04:31,360 --> 00:04:37,360
agencies once you've contacted them you can do basic things like freezing your

63
00:04:35,919 --> 00:04:41,199
credit for free or if you want something a little less

64
00:04:39,120 --> 00:04:46,000
intrusive than having your credit frozen you can pay for credit monitoring which

65
00:04:43,840 --> 00:04:51,680
will send you a report when anyone tries to open a new account or apply for

66
00:04:48,479 --> 00:04:53,520
credit in your name and that last one

67
00:04:51,680 --> 00:04:57,120
i know it's kind of a pain and to be quite frank i don't want to advocate for

68
00:04:55,840 --> 00:05:01,120
those credit monitoring companies because i think at least some of them

69
00:04:58,880 --> 00:05:05,360
are a bunch of yahoos and i don't mean that in like uh yahoo the company way i

70
00:05:03,360 --> 00:05:08,720
just i mean they're idiots i remember being on the phone with one

71
00:05:06,880 --> 00:05:14,080
of them and complaining that their site doesn't support two-factor authentication even though there's a

72
00:05:11,520 --> 00:05:17,919
blog post on their site from like three years ago recommending that you turn

73
00:05:15,919 --> 00:05:21,759
two-factor authentication on for any sensitive accounts like and the guy he

74
00:05:19,919 --> 00:05:26,320
didn't even the guy on the phone okay low-level customer service person

75
00:05:23,360 --> 00:05:30,400
whatever didn't even know what 2fa was you have a lot of sense of information

76
00:05:28,160 --> 00:05:34,080
in there anyway it's all you can really do and it's

77
00:05:32,160 --> 00:05:38,800
really important in the event of a leak that you take action swiftly if your

78
00:05:36,560 --> 00:05:42,479
information is out there because in some cases the company responsible for the

79
00:05:40,639 --> 00:05:47,360
leak might cover your monitoring fees anyway and the thing is is like you

80
00:05:44,639 --> 00:05:51,360
never know what could come back to bite you

81
00:05:48,720 --> 00:05:51,360
and where

82
00:05:51,759 --> 00:05:57,759
