1
00:00:00,280 --> 00:00:05,650
And Lou everybody when it comes to my advanced ethical hacking networking penetration testing goes

2
00:00:16,490 --> 00:00:23,420
in this video we are going to cover the concept of steganography steganography for many report.

3
00:00:23,420 --> 00:00:27,100
It's something that was coming from the older generation.

4
00:00:27,290 --> 00:00:32,540
It was not something about cryptography but it was just something about hiding stuff.

5
00:00:32,630 --> 00:00:44,330
But it comes back in about nineteen eighties and truly it means that so you hide something in something

6
00:00:44,430 --> 00:00:54,170
away you inside Freud you encrypt it or you can touch even cheat so that all you have is secret file

7
00:00:54,220 --> 00:00:57,470
or a secret text in favor of another file.

8
00:00:57,870 --> 00:00:58,590
OK.

9
00:00:58,620 --> 00:01:07,430
So in windows there is a common tool which names open both open book and then and then there is everyone

10
00:01:07,470 --> 00:01:10,910
on code which name is openness table.

11
00:01:11,060 --> 00:01:20,230
There you can try to message if I cover some fighters in how data extract data from them.

12
00:01:20,360 --> 00:01:28,300
Generates was senior to embed watermark or verify your watermark verify watermark and then you will

13
00:01:28,340 --> 00:01:30,800
have a very good option.

14
00:01:30,800 --> 00:01:34,410
It is the face of encryption algorithm.

15
00:01:34,610 --> 00:01:38,520
Then you could put your passport and then you would not confirm it in.

16
00:01:38,990 --> 00:01:40,310
You're going to hide data.

17
00:01:40,850 --> 00:01:45,280
But what about when the encryption phase then commission phase.

18
00:01:45,380 --> 00:01:46,040
It's easy.

19
00:01:46,250 --> 00:01:57,050
So in open stage in the limited session I mean in a baboon too you can have you have as an option A

20
00:01:57,110 --> 00:02:07,190
E S or one hundred twenty eight and then you have a s encryption two hundred fifty six.

21
00:02:07,220 --> 00:02:08,530
You have only two options.

22
00:02:08,550 --> 00:02:08,770
What.

23
00:02:08,800 --> 00:02:09,250
OK.

24
00:02:09,350 --> 00:02:16,570
Since we are on the Mac operating system we are going to show you how it works in your life and how

25
00:02:16,580 --> 00:02:21,250
you can hide it particular football if you don't want.

26
00:02:21,290 --> 00:02:27,250
If you want to send a photo to the web and you want to hide your ticks inside it.

27
00:02:27,470 --> 00:02:30,420
So it's a really well known tool.

28
00:02:30,550 --> 00:02:38,230
It's it's a really well known tool in my wedding system that you can use it and then the name is.

29
00:02:38,280 --> 00:02:40,810
I know it takes encryption.

30
00:02:40,850 --> 00:02:41,270
All right.

31
00:02:41,390 --> 00:02:42,310
So good defend.

32
00:02:42,600 --> 00:02:43,190
OK.

33
00:02:43,430 --> 00:02:52,040
Before getting into the practical part let's have a really quick view about what is exactly steganography

34
00:02:52,730 --> 00:02:57,260
in what is the meaning of it what it is used for.

35
00:02:57,590 --> 00:03:01,170
So how can we use it in your life.

36
00:03:01,270 --> 00:03:02,370
Right.

37
00:03:02,540 --> 00:03:07,350
So Steganography is the process of hiding one file in certain order.

38
00:03:07,430 --> 00:03:16,400
As we said earlier you can hide it text file into a image via most popular hiding a file within a picture

39
00:03:16,730 --> 00:03:23,330
if you are or are you are your phone of Mr. Wilburn you are likely already some of some somewhat familiar

40
00:03:23,330 --> 00:03:23,900
with this.

41
00:03:24,310 --> 00:03:24,820
Okay.

42
00:03:25,040 --> 00:03:29,260
So how are you going to find a lot of information and you can even use this.

43
00:03:29,450 --> 00:03:33,740
This only exists that I I'd to hide.

44
00:03:33,750 --> 00:03:36,930
There is not a complete state on most clinics disclose.

45
00:03:37,080 --> 00:03:42,890
Well it it is in most different policy twelve is including four are in a to meet.

46
00:03:43,310 --> 00:03:51,920
So there you cannot type pseudo man and then minus is state that still hide minus are in for one provision

47
00:03:52,000 --> 00:03:55,390
when I use this but when I tried to install this for us.

48
00:03:55,420 --> 00:04:04,010
Oh well you can try to install it by typing sudo aptitude I find I often get installed get it installed.

49
00:04:04,380 --> 00:04:09,470
OK the state does not have its ups and downs.

50
00:04:09,470 --> 00:04:16,280
One upside is that it is a lot better at hiding and can easily hide any final type.

51
00:04:16,280 --> 00:04:17,350
That's great.

52
00:04:17,390 --> 00:04:25,430
It does so by using an advanced I'm going to hide it within the image of all you file without changing

53
00:04:25,430 --> 00:04:25,850
the look.

54
00:04:25,850 --> 00:04:27,050
That's perfect.

55
00:04:27,050 --> 00:04:27,730
Over the file.

56
00:04:28,070 --> 00:04:36,180
So this is also means that without using state or state aid or at least this Democratic code approach

57
00:04:36,250 --> 00:04:41,390
as state aid it is very difficult to extract the heat and virus from the image.

58
00:04:41,390 --> 00:04:49,310
Much more on this when you when you hide or when you use the still graphic for hiding these teens in

59
00:04:49,310 --> 00:04:58,700
most cases just software you use for hiding the file you don't a person should use exactly the same

60
00:04:58,700 --> 00:05:03,300
software sometimes if you hide it instead of hide and then meet.

61
00:05:03,340 --> 00:05:03,810
I am.

62
00:05:04,040 --> 00:05:11,540
I know that I am on open to stay or go Guys I'm telling you in most cases it won't work.

63
00:05:11,900 --> 00:05:18,300
We have to have both side this same version decent version but the same software.

64
00:05:18,300 --> 00:05:18,970
All right.

65
00:05:19,050 --> 00:05:25,690
So many of you have so many comments that you can type if your own Terry not or if you are familiar

66
00:05:25,690 --> 00:05:29,810
with a Jew I interpret it maybe better.

67
00:05:29,830 --> 00:05:30,080
OK.

68
00:05:30,120 --> 00:05:35,850
This is a very well known Web site so that you can quote more information and test the more information

69
00:05:36,180 --> 00:05:40,720
you know to find out exactly what it is and how it works stuff right.

70
00:05:41,050 --> 00:05:41,600
OK.

71
00:05:41,820 --> 00:05:46,730
So now let's go into the main part which is the practical part.

72
00:05:47,160 --> 00:05:47,680
All right.

73
00:05:47,850 --> 00:05:51,460
So we have this software and then you click on it.

74
00:05:51,460 --> 00:05:52,760
So by clicking on it.

75
00:05:52,770 --> 00:05:53,880
So what do we want.

76
00:05:54,240 --> 00:06:01,320
We want to hide it takes in into any image and send that image to a friend.

77
00:06:01,650 --> 00:06:09,270
And then that will by clicking on that image he or she might think that it's just an image but the EU

78
00:06:09,480 --> 00:06:13,260
as you know you wanted your text to be secret.

79
00:06:13,260 --> 00:06:19,890
You said a misstep or a miss is something that you're going out finally to find out.

80
00:06:19,890 --> 00:06:25,300
I use this software on that software and then that password that I've used to encrypt it.

81
00:06:25,320 --> 00:06:33,780
Is this is this at the time when he download the file or your picture from Facebook or from Google form

82
00:06:33,870 --> 00:06:41,530
anything and then you will not be able to see the text or while using the software that you sent earlier

83
00:06:41,670 --> 00:06:42,140
to him.

84
00:06:42,360 --> 00:06:47,040
So he might get disposability to read you two with your text.

85
00:06:47,040 --> 00:06:47,450
OK.

86
00:06:47,480 --> 00:06:51,430
So let's quote make it well here.

87
00:06:52,010 --> 00:06:55,610
You have to type your password or key your password.

88
00:06:55,610 --> 00:06:58,120
I can see no password.

89
00:06:58,220 --> 00:07:06,540
OK I type your password I can be sure to see OK this is how it looks.

90
00:07:06,590 --> 00:07:06,850
OK.

91
00:07:06,860 --> 00:07:09,930
Your password are small letters.

92
00:07:10,070 --> 00:07:10,910
All right.

93
00:07:11,030 --> 00:07:17,990
Blowfish is a type of encryption serpent to fish.

94
00:07:18,460 --> 00:07:20,350
Just go go with them guys.

95
00:07:20,360 --> 00:07:23,620
They are fairly well known but us.

96
00:07:23,690 --> 00:07:36,470
We use the R E S Two hundred and fifty six because its foot was not the best but E N I S T from USA

97
00:07:36,500 --> 00:07:41,780
did considering it as a very well and a good encryption standard.

98
00:07:42,050 --> 00:07:43,270
So many people use it.

99
00:07:43,280 --> 00:07:50,020
It's so popular and it's so powerful as well for encrypting things so you can use it instead of these

100
00:07:50,020 --> 00:07:50,530
older ones.

101
00:07:50,530 --> 00:07:58,490
What I didn't say these are not powerful but it is I do know at 100 percent if you hide things it will

102
00:07:58,490 --> 00:08:02,900
take a long long long long long long long time to the attacker to decode.

103
00:08:03,390 --> 00:08:03,750
OK.

104
00:08:03,890 --> 00:08:07,700
So we are not in the video of talking about it.

105
00:08:07,730 --> 00:08:13,370
Now we will see it in the next video because we have it part on we should that we are going to talk

106
00:08:13,370 --> 00:08:15,890
about cryptographic fees.

107
00:08:15,920 --> 00:08:16,520
All right.

108
00:08:16,520 --> 00:08:25,640
So we which was is and then here we want that type of message we can type blah blah blah blah or let's

109
00:08:25,640 --> 00:08:28,820
go here and copy some ticks.

110
00:08:29,000 --> 00:08:29,540
Let's go.

111
00:08:29,540 --> 00:08:40,820
This could be corporate mistakes and then you go back and you can place in there if you want.

112
00:08:40,830 --> 00:08:43,000
It doesn't matter if we get it.

113
00:08:43,880 --> 00:08:44,570
All right.

114
00:08:44,870 --> 00:08:47,470
So now you're going to click on input.

115
00:08:48,020 --> 00:08:50,700
Why did you click on include.

116
00:08:50,720 --> 00:08:57,260
It will encrypt your text and then then put the index would be here by the 8.

117
00:08:57,320 --> 00:09:00,530
You can just copy the text which would be going to hear.

118
00:09:00,560 --> 00:09:01,020
OK.

119
00:09:01,260 --> 00:09:01,580
OK.

120
00:09:02,420 --> 00:09:03,470
Which would be good to hear.

121
00:09:03,470 --> 00:09:14,260
And then you can send it to a friend as a encrypting text but you might want as well to embed your texts

122
00:09:15,610 --> 00:09:21,370
into any image we're going to showing you both steps.

123
00:09:21,430 --> 00:09:25,620
First thing first let's check any good.

124
00:09:25,700 --> 00:09:26,440
All right.

125
00:09:26,490 --> 00:09:28,650
So this is the text that we get.

126
00:09:28,650 --> 00:09:33,840
So you just copy eat Kobe after occupying it.

127
00:09:33,840 --> 00:09:39,900
You put it here and then you can send it to your friend and then say say to him that hey I use this

128
00:09:39,900 --> 00:09:44,420
software analytics intuition for privacy and this vision is a vision.

129
00:09:44,460 --> 00:09:49,950
I use Android s to five six and then my password was this was this.

130
00:09:49,950 --> 00:09:57,180
And then we were going to get these tics back in and what if we want to send that text in an image file.

131
00:09:57,450 --> 00:09:58,730
Okay.

132
00:09:58,740 --> 00:10:01,700
So we will do it OK.

133
00:10:01,790 --> 00:10:09,830
So we have shown you earlier how you can just just copy the text and an encrypted and then send it to

134
00:10:09,830 --> 00:10:10,750
your phone.

135
00:10:10,760 --> 00:10:17,960
But what I would put the plain tags into any message so that we hide it into any image and then we send

136
00:10:17,960 --> 00:10:19,340
that image to friends.

137
00:10:19,400 --> 00:10:19,730
OK.

138
00:10:20,000 --> 00:10:22,480
So this is the time.

139
00:10:22,520 --> 00:10:24,410
Now we want to do it.

140
00:10:24,440 --> 00:10:33,930
You go there and then just copy comments see or just click and click ok and copy it.

141
00:10:34,090 --> 00:10:36,030
Now we're going to pass it to you.

142
00:10:36,340 --> 00:10:38,150
You cannot take anything.

143
00:10:38,150 --> 00:10:40,210
Oh okay.

144
00:10:40,250 --> 00:10:42,320
Kill kill kill kill kill kill kill.

145
00:10:42,650 --> 00:10:43,340
That's good.

146
00:10:43,370 --> 00:10:44,270
That's good.

147
00:10:44,300 --> 00:10:44,690
Yeah.

148
00:10:44,690 --> 00:10:46,610
Did you get anything.

149
00:10:46,620 --> 00:10:54,040
So now we're going to be I'm going to click on input because we want to insert these states into any

150
00:10:54,040 --> 00:10:54,710
image fire.

151
00:10:55,130 --> 00:10:55,640
All right.

152
00:10:55,640 --> 00:10:56,690
So let's go to you.

153
00:10:57,330 --> 00:11:02,330
Oh so that you can see of good software within one woman.

154
00:11:03,380 --> 00:11:04,440
OK.

155
00:11:04,550 --> 00:11:10,240
So you can heal then you could include and make Stina the steam guy.

156
00:11:10,250 --> 00:11:12,050
No ground jumping right.

157
00:11:12,500 --> 00:11:13,190
Yeah.

158
00:11:13,420 --> 00:11:20,630
OK we are music fans are looking to this player and then we crack open but this is the image that we

159
00:11:20,630 --> 00:11:25,610
are going to include we could continue it.

160
00:11:25,850 --> 00:11:26,780
It's working.

161
00:11:26,840 --> 00:11:27,540
All right.

162
00:11:27,560 --> 00:11:34,270
So it seems to all that this fight is in users a deep path.

163
00:11:34,280 --> 00:11:40,630
My P.T. e fries strictly stick nanograms path we click.

164
00:11:40,640 --> 00:11:41,030
Okay.

165
00:11:41,050 --> 00:11:42,890
So now go back.

166
00:11:43,670 --> 00:11:44,770
Let's go.

167
00:11:44,990 --> 00:11:45,690
You.

168
00:11:46,300 --> 00:11:47,210
This is my music.

169
00:11:47,210 --> 00:11:48,050
We don't need it anymore.

170
00:11:48,050 --> 00:11:49,800
We can go to that path.

171
00:11:49,880 --> 00:11:51,180
This one.

172
00:11:51,320 --> 00:11:52,740
Let's go to this one.

173
00:11:52,760 --> 00:11:53,550
Okay.

174
00:11:53,570 --> 00:11:54,890
This is it.

175
00:11:54,890 --> 00:11:55,530
This one.

176
00:11:55,820 --> 00:11:57,780
Let's go and double it.

177
00:11:58,050 --> 00:12:00,060
Oh it's nice.

178
00:12:00,320 --> 00:12:03,920
You always saying that inside this image.

179
00:12:03,920 --> 00:12:05,210
There is a text.

180
00:12:05,330 --> 00:12:06,940
No one would say that you know.

181
00:12:07,280 --> 00:12:14,330
So let's let's check the size of it.

182
00:12:14,350 --> 00:12:27,090
Get in for it's 1 7 9 nine eight seven right so too much.

183
00:12:27,490 --> 00:12:30,470
Okay let's go back to you.

184
00:12:30,470 --> 00:12:31,210
It hurts.

185
00:12:31,320 --> 00:12:35,480
Oh I mean it's too easy to get in for.

186
00:12:35,530 --> 00:12:39,360
You see guys some different some different.

187
00:12:40,060 --> 00:12:42,700
Okay so now what are we going to do.

188
00:12:42,760 --> 00:12:49,570
What are we going to do is we have to sing that fire to old friends and then so that he can get it and

189
00:12:51,190 --> 00:12:59,080
use the same software as we use the same password as we used and then the A E is we're going to tell

190
00:12:59,080 --> 00:13:00,780
you what why is that.

191
00:13:00,790 --> 00:13:05,270
It's the same password because a guest is Sue me tweak encryption.

192
00:13:05,290 --> 00:13:07,120
When are we going to get into that.

193
00:13:07,120 --> 00:13:09,190
Call me when I explain you.

194
00:13:09,190 --> 00:13:14,410
What is this symmetric encryption and what is the encryption key.

195
00:13:14,710 --> 00:13:18,950
So what does it give you symmetric encryption.

196
00:13:18,970 --> 00:13:24,640
Use the same password for encrypting for a pretty symmetric encryption.

197
00:13:24,640 --> 00:13:26,470
Does it use the same password.

198
00:13:26,470 --> 00:13:27,310
All right.

199
00:13:27,370 --> 00:13:28,300
So this is it.

200
00:13:28,360 --> 00:13:30,180
Now we can close this.

201
00:13:30,280 --> 00:13:31,350
We don't use it anymore.

202
00:13:31,570 --> 00:13:32,210
OK.

203
00:13:32,420 --> 00:13:33,260
What are you going to do.

204
00:13:33,270 --> 00:13:36,830
I'm going to try to we'll need to go through it.

205
00:13:37,060 --> 00:13:44,890
We went looking at that password was nor was your password.

206
00:13:45,390 --> 00:13:47,760
Let's check you sort of make it OK.

207
00:13:47,770 --> 00:13:48,970
It's already.

208
00:13:49,110 --> 00:13:51,270
Now we have to decode that file.

209
00:13:51,360 --> 00:13:53,790
Let's say that we are not that point.

210
00:13:54,060 --> 00:14:00,120
You have to click on decrypt decreed that we are going to hit me click here.

211
00:14:00,990 --> 00:14:01,770
It's working.

212
00:14:01,770 --> 00:14:02,940
Here we go guys.

213
00:14:02,990 --> 00:14:04,080
Here we are.

214
00:14:04,110 --> 00:14:04,880
Everything.

215
00:14:04,890 --> 00:14:05,700
Everything.

216
00:14:05,700 --> 00:14:08,260
This empathic quote and this thing.

217
00:14:08,520 --> 00:14:17,630
Let's say if we want to know the password Lucy was one and then we tried to put again this implied we

218
00:14:17,630 --> 00:14:22,210
shouldn't at any organization it code password or anybody.

219
00:14:22,490 --> 00:14:25,800
Steve Gano glad you see this is exactly how it works.

220
00:14:25,870 --> 00:14:29,640
So I hope this feeling was very informative for you.

221
00:14:29,940 --> 00:14:32,910
And then we are looking forward to seeing the next video.

222
00:14:32,940 --> 00:14:34,600
Thank you for watching.
