Website hacking and prevention (All Tools,Topics & Technique )Jay Nagar
This document discusses the Heartbleed vulnerability in OpenSSL and its potential impacts. Heartbleed is a bug in the OpenSSL cryptography library that exposes the contents of the server's memory, including private keys and user session cookies. An attacker can exploit Heartbleed to steal sensitive data from vulnerable servers or impersonate services. The vulnerability had widespread implications because OpenSSL is used to secure a majority of websites. While patching servers and changing passwords addressed direct theft of information, Heartbleed also weakened the security of encrypted communications and online identities.
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.

The document discusses the need for web application firewalls to protect against modern web application attacks. It notes that traditional network firewalls and intrusion prevention systems are inadequate because they operate at the network layer and do not understand the application layer protocols used in web applications. The document promotes the Cyberoam web application firewall as a solution, highlighting its positive security model using an intuitive website flow detector to learn normal application behavior and block deviations without signatures. It also lists features such as protection against attacks like SQL injection, monitoring and reporting, and help with PCI compliance.
The document discusses the Open Web Application Security Project (OWASP) and the top 10 web application vulnerabilities according to OWASP. These include injection flaws, broken authentication, cross-site scripting, insecure direct object references, security misconfiguration, sensitive data exposure, missing access controls, cross-site request forgery, use of vulnerable components, and unvalidated redirects/forwards. It provides details on each vulnerability and recommendations for countermeasures.
The document discusses factors that affect the likelihood and impact of threats from script injection vulnerabilities like SQL injection and cross-site scripting (XSS) attacks on web applications. It outlines several factors for the threat agent and vulnerability that contribute to high likelihood scores, such as automated tools being available to exploit vulnerabilities easily. It also discusses technical and business impacts that could result from loss of confidentiality or availability due to such attacks.
Web services allow different applications to communicate over the web using XML. They operate on the server side and can perform tasks when called by client applications. While web services provide application integration, they also present some security concerns like buffer overflows, XML injections, and session hijacking that could allow attackers to damage systems or steal data. Tools are available to help secure web applications and detect vulnerabilities in web services.
Web security deals with protecting data transferred over the internet and networks from security threats and risks. Common web security threats include cross-site scripting, SQL injection, phishing, ransomware, and viruses. To help prevent these threats, it is important to keep software updated, beware of SQL injection attacks, validate all user input, use strong passwords, and limit information in error messages. Proper web security helps protect websites, networks, and data from damage or theft.
The document discusses the Open Web Application Security Project (OWASP) and its Top 10 vulnerabilities. OWASP is an open source non-profit organization dedicated to web application security.

HijackLoader Evolution: Interactive Process HollowingDonato Onofri
CrowdStrike researchers have identified a HijackLoader (aka IDAT Loader) sample that employs sophisticated evasion techniques to enhance the complexity of the threat. HijackLoader, an increasingly popular tool among adversaries for deploying additional payloads and tooling, continues to evolve as its developers experiment and enhance its capabilities.
In their analysis of a recent HijackLoader sample, CrowdStrike researchers discovered new techniques designed to increase the defense evasion capabilities of the loader. The malware developer used a standard process hollowing technique coupled with an additional trigger that was activated by the parent process writing to a pipe. This new approach, called "Interactive Process Hollowing", has the potential to make defense evasion stealthier.
