Cyber extortion is a crime involving an attack or threat of attack against an enterprise, coupled with a demand for money to stop the attack.
Cyber extortions have taken on multiple forms - encrypting data and holding it hostage, stealing data and threatening exposure, and denying access to data.
Malware locks out the user’s system and demands ransom.
Creates “Zombie Computer” operated remotely.
Individuals and business targeted.
This form of extortion works on the assumption that the data is important enough to the user that they are willing to pay for recovery.
There is however no guarantee of actual recovery, even after payment is made.
The first known ransomware was the 1989 "AIDS" trojan (also known as "PC Cyborg") written by Joseph Popp.
This presentation is about Ransomware. It tells you about how ransomware creates problem and how it can be removed. It also describes different types of Ransomware.
Ransomware is a hot topic that isn't going away anytime soon. As more strains of this nasty malware are born, it's important to have a clear understanding about what this threat could mean for your business!
Hospitals, school districts, state and local governments, law enforcement agencies, small businesses, large businesses—these are just some of the entities impacted recently by ransomware, an insidious type of malware that encrypts, or locks, valuable digital files and demands a ransom to release them. And, of course, home computers are just as susceptible to ransomware, and the loss of access to personal and often irreplaceable items—including family photos, videos, and other data—can be devastating for individuals as well.

Ransomware is a PC or Mac-based malicious piece of software that encrypts a user or company’s files and forces them to pay a fee to the hacker in order to regain access to their own files.
Not only can ransomware encrypt the files on your computer; the software is smart enough to travel across your network and encrypt any files located on shared network drives. This can lead to a catastrophic situation whereby one infected user can bring an entire company to a halt.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
Let's dive deeper into the world of ODC! Ricardo Alves (OutSystems) will join us to tell all about the new Data Fabric. After that, Sezen de Bruijn (OutSystems) will get into the details on how to best design a sturdy architecture within ODC.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

enterprise, coupled with a demand for money
to stop the attack.
• Cyber extortions have taken on multiple forms
- encrypting data and holding it hostage,
stealing data and threatening exposure, and

6. RANSOMWARE DEFINED…
Malware locks out the user’s system and demands

Creates “Zombie Computer” operated remotely.
Individuals and business targeted.
This form of extortion works on the assumption that
the data is important enough to the user that they are
willing to pay for recovery.
There is however no guarantee of actual recovery, even
after payment is made.
7. HISTORY
The first known ransomware was the 1989
"AIDS" trojan (also known as "PC Cyborg")
written by Joseph Popp.
8. TYPES OF RANSOMWARE
Encryption Ransomware - Locker Virus and
Onion Ransomware
Locker Ransomware - Reveton
12. Reveton
In 2012, a major ransomware worm known as Reveton
began to spread.
It is also known as "police trojan".
Its payload displays a warning from a law enforcement
agency.
Claiming that the computer had been used for illegal
activities, such as downloading pirated software, promoting
terrorism, copyright etc.
The warning informs the user that to unlock their system
they would have to pay a fine.
To increase the illusion that the computer is being tracked
by law enforcement, the screen also displays the
computer's IP address and footage from a computer's
webcam.
13. CryptoLocker
A Encrypting ransomware reappeared in 2013.
Distributed either as an attachment to a malicious e-mail.
Cryptolocker was also propagated using the Gameover
ZeuS.
Encrypts certain types of files stored on local drives using
RSA public-key cryptography.
The private key stored only on the malware's control
servers.
Offers to decrypt the data if a payment is made by a
stated deadline.
Threatens to delete the private key if the deadline passes.
It was isolated in May 2014,when a Gameover botnet was
knocked out.
17. HOW TO PREVENT BEING A VICTIM
Keep all of the software on your computer up to
date.
Make sure automatic updating is turned on to get
all the latest Microsoft security updates and
browser-related components (Java, Adobe, and
the like).
Keep your firewall turned on.
Don't open spam email messages or click links on
suspicious websites. (CryptoLocker spreads via
.zip files sent as email attachments, for example.)
18. Experts advise taking these steps to avoid attacks or
protect yourself after an attack:
Use reputable antivirus software and a firewall.
Back up often.
Exercise caution.
Disconnect from the Internet.
Alert authorities.
Update your security software.
19. REMOVAL OF MALWARES FROM
WINDOWS PC
Step 1: Enter Safe Mode
Step 2: Delete Temporary Files
Step 3: Download Malware Scanners
Step 4: Run a Scan With Malwarebytes
Step 5: Fix Your Web Browser
Step 6: Recover Your Files If Windows Is Corrupt

'Tox' Offers Free build-your-own Ransomware
Malware Toolkit.
Tox is completely free to use.
One dark web hacker has released this for anyone
to download and set up their own ransomware
for free.
Tox, which runs on TOR, requires not much
technical skills to use.
It is designed in such a way that almost anyone
can easily deploy ransomware in three simple
steps.
25. Make your own Ransomware
Once a user register with the site, follow these
three simple steps to creating your own
malware:
Type a desired ransom amount you want to ask
victims for.
Provide an additional note in the "Cause", the
message that will alert victims that they are
being held hostage to a piece of malware.
Finally, you are prompted to fill out a captcha,
and click "Create".
26. "This process creates an executable of about 2MB that
is disguised as a .scr file.
Then the Tox [users] distribute and install as they see
fit. The Tox site (runs on the TOR network) will track the
installs and profit. To withdraw funds, you need only
supply a receiving Bitcoin address.“
- McAfee explains..
27. CONCLUSION
When it comes to malware attacks, knowledge is
the best possible weapon to prevent them.
Be careful what you click!!
Preventive measures should be taken before
Ransomwares establish strong hold.
Keeping all the software updated and getting
latest security updates might help to prevent the
attacks.
