Hello, My Youtube Friends. :D
Digiboy16 Back. :D
in their Ethical hacking and Infosec channel every weekend
Cyber_Security_Environment
Today we have a super special Chapter.
Today we going to analyze SMTP packets
Let's Get started.
We have a previously captured capture.
We have all the packets about SMTP
The first step is we have our Host
with the IP address 192.168.0.12
and the server with 192.168.0.13
Basically there are two virtual machines.
vmware virtual machines, with our source and destination
The first three packets are the three way handshake
SYN, SYN ACK, ACK
After the Three way handshake started
start the server giving the server information
Here's the SMTP, show's the SMTP information
The version and the date
Here we have the 25 PORT that's the SMTP port. That's the destination port about our customer.
is 1713
Later the next one is an Extended hello EHLO
to the next one server
and that's the command
And later this continue verifying the SMTP parameters
Here's the code 250 Indicating the OK code.
With different parameters.
After the server verify the parameters, the customer start with the MAIL FROM
who's the sender
martin.tor@4salet.com
Later the server is with the 250 code. Indicating everything is ok
The next one is the reception to. who is the destination.
in this case is bert.manly@five8nine.com
Later send the 250 CODE indicating the OK code.
Here we go to the DATA section, that is the message to the destination
the server indicates to the customer that start with a code and finish with the same code.
as we can see here
After the message is done, the DATA is fragmented, in this case is 593 bytes
The next one packet is an ACK packet indicating everything is ok
later appear a IMF packet, Internet message format
The message ID
indicating the from and the destination.
and the Subject with the encoding subject
and many other information
and everything was in text plain
and a little bit server information
Later everything was OK with the IMF protocol.
the next step is the verification step.
that everything is OK with the 250 code.
and to finish is with the QUIT code from the customer to finish everything.
and the next one is from the server to close the session.
and the TCP packets with the FIN ACK, ACK
in both sides Customer and server.
That's everything for today.
See you Next Weekend, BYE!

Oona, how's the new doctor doing?
Honestly?
Yes.
Ehh...
It may take her some time.
You were new once, remember?
Also, can you...?
Fix these? I'll try.
Maple syrup: Done and done!
Sign here, pal. Thanks, Oro.
Does this mean I can get back t--
To work? Not exactly.
When I was topping off the syrup,
I noticed that your lab doesn't have mummy protection.
Is that a problem?
[mummy growling]
I would say yes.
I can fix 'er right up.
Things are a little slow in my department.
♪ [Odd Squad theme ringtone]
Howdy-do.
Hey, Oola!
It's "Oona."
Listen, budster,
got a little prob-ski up here in the med bay-ski.
Lil' help from an old friend-ski?
Look, I've got a huge pile of gadgets to fix.
Is there any way...
[shout]
[imitating machine] If you want to help me,
please press or say one.
One.
Yes, please fix the mummy thing.
Excuse me.
So, this seems not normal.
Did you look in old Dr. O's book for a cure?
'Course I did!
But it was garbage.
Where's the book?
In the garbage.
[sigh]
To cure hammerhead-osis,
give the patient a zebra leaf that's 16 inches long.
Do you have zebra plant leaves?
Tons.
So we just measure them with a ruler like I showed you.
Nice try, Mozart,
but this ruler only goes up to 12 inches,
not 16.
I think the only solution is...
[whispering] She's a hammerhead forever.
No, the way it works,
you just need to hold your place.
So you lay the ruler down and measure to the 12 mark.
Then you put your finger here to hold your place
and move the ruler to where your finger is.
Now you add to the number you already have.
Twelve plus four equals sixteen inches exactly.
Just give her this leaf and she's good to go.
I love how we work together.
Those cafeteria workers are going down.
Dowwwwwwn!
I really don't have anything against the cafeteria staff.
Then why're you wearing that anti-caf shirt?
How did you do that?
I think the better question is:
how did I get that flatbread sandwich in your pocket?

F 18 fighter plane captures stunning UFO on video… government - Duration: 4:19.
F-18 fighter plane captures stunning UFO on video� government admits UFO research is
real
by: Ethan Huff
Following the release of a new report from The New York Times (NYT) about efforts by
the United States government to investigate unidentified flying objects (UFOs) as a potential
threat to national security, some amazing video footage has now been released suggesting
that this threat may be more imminent than previously thought.
There have been at least two separate incidents now in which a U.S. Navy F/A-18 fighter jet
apparently captured infrared video footage of what appears to be UFOs flying around in
space.
The one video contains audio of a conversation between the pilot and his weapons officer,
both of whom sound flabbergasted over what they saw before their very eyes.
The second video actually shows the plane�s radar apparatus locking onto the UFO, which
is seen moving so quickly that it disappears offscreen before it can be fully tracked.
In an interview with NPR, portions of which were relayed by PJ Media�s Rick Moran, an
intelligence officer by the name of Luis Elizondo who headed up the Pentagon program responsible
for probing UFOs explained how the intelligence asset is often unsure about what it sees flying
in the sky � and this anomalous footage is no exception.
�If you�re asking my personal opinion from here, look, I�ve got to be honest with
you, I don�t know where it�s from.
But we�re pretty sure it�s not here,� Elizondo is quoted as saying, noting that
the objects seen often move and rotate with almost magic-like ease and speed.
�Now does that mean it�s �out there?� Whether or not it�s Russian or Chinese inside
or little green men from Mars or frankly your neighbor�s dog, I wanted to purposely steer
away from that because I wanted to focus on truly the raw science: what were we seeing
and did it pose a threat to national security.�
Is Big Brother faking �disclosure� in order to pull of a massive �cosmic false
flag� attack?
As interesting as this all might seem � the video and audio captured speak for themselves
� the release of this information at a time such as this in human history is potentially
suspect.
That�s because, with things seemingly heating up in the space realm these days, it seems
just a little bit too convenient that Big Brother has chosen now to suggest that UFOs
may, indeed, be real.
Dr. Stephen Greer from Sirius Disclosure is one such skeptic who believes that the UFO
and �extraterrestrial� narrative is all a ruse by the government to cover for manufactured
false flag events of a cosmic nature that could one day be used to fake an alien invasion.
According to Dr. Greer, a large percentage of the so-called �UFO� events that are
being witnessed or reported around the world do not originate from outer space.
In his opinion, these are manufactured events by humans � mainly the military industrial
complex � to trick humanity into believing that the world is being invaded by ET beings
from other planets or galaxies.
What would be the purpose of this?
In the view of Dr. Greer, certain government entities might try to use it as a cover in
the event that enough people in society become awakened to the truth of things and start
to challenge the status quo.
�If someone tries to stage an event, we�re all going to call it out as the hoax that
it is� and not go along with that what I�m calling �scripted Armageddon,'� Dr. Greer
is quoted as saying.
�They would love to see a shut down of our civilization and the extermination of about
five billion people, through a conflict that they will stage, and they will manufacture
Armageddon � the big one is going to be the launch of a hoaxed attack on the planet
that would look 100% like an extraterrestrial event � and it is not.�
