Web Application Pentesting
* Process to check and penetrate the security of a web application or a website
* process involves an active analysis of the application for any weaknesses, technical flaws, or vulnerabilities
* Any security issues that are found will be presented to the system owner, together with an assessment of the impact, a proposal for mitigation or a technical solution.
This presentation lets you understand about the biggest cyber-attack extortion in the history of the internet. It contains all details of what, how and whys of WannaCry Ransomware.

Internet worms definitions and strategies to avoid it. Compromising the availability and reliability of systems through security failure
In November 1988, a program was deliberately released that spread itself throughout Digital VAX and Sun workstations across the Internet. It exploited security vulnerabilities in Unix systems.
In itself, the program did no damage but it’s replication and threat of damage caused extensive loss of system service and reduced system responsiveness in thousands of host computers.
This program has become known as the Internet Worm.
This was the first widely distributed Internet security threat.
Strange files appeared in systems that were infected.
Strange log messages appeared in certain programs.
Each infection caused a number of processes to be generated. As systems were constantly re-infected, the number of processes grew and systems became overloaded.
Some systems (1000s) were shut down because of the problems and because of the unknown threat of damage.
Program was made up of two parts
A main program that looked for other machines that might be infected and that tried to find ways of getting into these machines;
A vector program (99 lines of C) that was compiled and run on the infected machine and which then transferred the main program to continue the process of infection.
Security vulnerabilities
fingerd - an identity program in Unix that runs in the background;
sendmail - the principal mail distribution program;
Password cracking;
Trusted logins.
Written in C and runs continuously.
C does NOT have bound checking on arrays. fingerd expects an input string but the writer of the worm noticed that if a longer string than was allowed for was presented, this overwrote part of memory.
By designing a string that included machine instructions and that overwrote a return address, the worm could invoke a remote shell (a Unix facility) that allowed priviledged commands to be executed.
sendmail routes mail and the worm took advantage of a debug facility that was often left on and which allowed a set of commands to be issued to the sendmail program.
This allowed the worm to specify that information should be transferred to new hosts through the mail system without having to process normal mail messages.
Unix passwords are encrypted and, in the encrypted form, are publicly available in /etc/passwd.
The worm encrypted lists of possible passwords and compared them with the password file to discover user passwords.
It used a list of about 400 common words that were known to be used as passwords.
It exploited fast versions of the encryption algorithm that were not envisaged when the Unix scheme was devised.
On Unix, tasks can be executed on remote machines.
To support this, there is the notion of a trusted login so that if a login command is issued to machine Z from user Y in machine X then Z assumes that X has carried out the authentication and that Y is trusted; no password is required.
The worm exploited this by looking for

SCADA Security: The Five Stages of Cyber GriefLancope, Inc.
Every time a new information technology finds its way into production, it seems as though we end up repeating the same process – security vulnerabilities will be discovered and disclosed in that technology, and users and vendors will deny that the risks are significant. Only after major attacks occur do we really start to see efforts to address the inherent risks in a systematic way.
We’re falling into this exact same trap again with Industrial Control and SCADA systems, but in this case the problem is worse, because the inherent nature of control systems prevents us from applying many of the strategies that have been used to protect other kinds of computer networks.
Join Lancope’s Director of Security Research, Tom Cross, for a look at the five stages of grief that organizations seem to pass through as they come to terms with security risks, and how far we’ve come regarding Industrial Control Systems.
Hear about:
The state of Control Systems security vulnerabilities
Attack activity that is prompting a change in perspective
The unique, long-term challenges associated with protecting SCADA networks

Internet threats are difficult to defend.
Malware defensive tools use more of ‘Botnets’
Fighting malware is asymmetric,favouring attackers.
P2P botnets are used as its more resilent
Using re-engineering existing malware, defenders can build antidotes to eradicate spreading functions.
Antidote can be used to monitor on-site activity of the malwares.
Malware families such as Hlux, Sality, Zeus would be most effective approach.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

The Internet Worm
– Compromising the availability and
reliability of systems through
security failure
2. Internet work case study., 2012 Slide 2
What happened
• In November 1988, a program was deliberately
released that spread itself throughout Digital VAX and
Sun workstations across the Internet. It exploited
security vulnerabilities in Unix systems.
• In itself, the program did no damage but it’s
replication and threat of damage caused extensive
loss of system service and reduced system
responsiveness in thousands of host computers.
• This program has become known as the Internet
Worm.
• This was the first widely distributed Internet security
threat.
3. Internet work case study., 2012 Slide 3
Terminology
• A worm
– This is a program that can autonomously spread itself across
a network of computers.
• A virus
– This is a program that can spread itself across a network of
computers by attaching itself to some other program or
document.
• A trapdoor
– This is a vulnerability in a program that allows normal security
controls to be bypassed.
4. Internet work case study., 2012 Slide 4
Consequences of the worm
• Strange files appeared in systems that were infected.
• Strange log messages appeared in certain programs.
• Each infection caused a number of processes to be
generated. As systems were constantly re-infected, the
number of processes grew and systems became
overloaded.
• Some systems (1000s) were shut down because of the
problems and because of the unknown threat of
damage.
5. Internet work case study., 2012 Slide 5
Worm description
• Program was made up of two parts
– A main program that looked for other machines that might
be infected and that tried to find ways of getting into these
machines;
– A vector program (99 lines of C) that was compiled and run
on the infected machine and which then transferred the main
program to continue the process of infection.
• Security vulnerabilities
– fingerd - an identity program in Unix that runs in the
background;
– sendmail - the principal mail distribution program;
– Password cracking;
– Trusted logins.
6. Internet work case study., 2012 Slide 6
fingerd
• Written in C and runs continuously.
• C does NOT have bound checking on arrays. fingerd
expects an input string but the writer of the worm
noticed that if a longer string than was allowed for
was presented, this overwrote part of memory.
• By designing a string that included machine
instructions and that overwrote a return address, the
worm could invoke a remote shell (a Unix facility) that
allowed priviledged commands to be executed.
7. Internet work case study., 2012 Slide 7
sendmail
• sendmail routes mail and the worm took advantage of
a debug facility that was often left on and which
allowed a set of commands to be issued to the
sendmail program.
• This allowed the worm to specify that information
should be transferred to new hosts through the mail
system without having to process normal mail
messages.
8. Internet work case study., 2012 Slide 8
Password cracking
• Unix passwords are encrypted and, in the encrypted
form, are publicly available in /etc/passwd.
• The worm encrypted lists of possible passwords and
compared them with the password file to discover
user passwords.
• It used a list of about 400 common words that were
known to be used as passwords.
• It exploited fast versions of the encryption algorithm
that were not envisaged when the Unix scheme was
devised.
9. Internet work case study., 2012 Slide 9
Trusted logins
• On Unix, tasks can be executed on remote machines.
• To support this, there is the notion of a trusted login
so that if a login command is issued to machine Z
from user Y in machine X then Z assumes that X has
carried out the authentication and that Y is trusted; no
password is required.
• The worm exploited this by looking for machines that
might be trusted. It did this by examining files that
listed machines trusted by the current machine and
then assumed reciprocal trust.
10. Internet work case study., 2012 Slide 10
Killing the worm
• The main effects of the worm were in the US and
system managers worked for several days to devise
ways of stopping the worm.
• These involved devising modifications to the
programs affected so that the worm could not
propagate itself, distributing these changes, installing
them then rebooting infected machines to remove
worm processes.
• The process took several days before the net was
cleared of infection.
11. Internet work case study., 2012 Slide 11
What we learned
• Security vulnerabilities result from flaws and these
will always be with us. Problems can be fixed but
new problems can arise with new versions of
software.
• Diversity is good - we need a heterogeneous not a
homogeneous network.
• Isolationism is not the answer - those sites that
disconnected from the network were amongst the last
to resume service.
12. Internet work case study., 2012 Slide 12
The perpetrator
• The perpetrator was a student at Cornell University
• He was discovered fairly quickly and charged.
• His sentence was for a period of community service
and a $10, 000 fine
– This was relatively light as the major thrust of his defence
was that the program explicitly did not cause deliberate
damage and, in fact, he had tried (but failed) to ensure that
too many processes would not be generated on host
machines
• Now a professor at MIT (not working in security)
13. Internet work case study., 2012 Slide 13
Warning
• Students before and since this infection have been
curious about security and have written experimental
programs. Few of these students are wicked and
many of them are very competent programmers.
• However, the consequences of experiments that go
wrong are now so great that network authorities do
not distinguish between stupidity and malice. There
are severe penalties for any experiments that
compromise system security.
14. Internet work case study., 2012 Slide 14
Finding out more
• Communications of the ACM, 32 (6), June 1989 has
