Man in The Middle Attack
A man-in-the-middle (MITM) attack intercepts communications between two parties by relaying and controlling messages between them. The attacker eavesdrops and potentially modifies the communication by replacing the keys for their own. This allows them to intercept sensitive transmissions like passwords or financial transactions. A MITM works by spoofing the MAC address of the target to intercept and manipulate traffic between the target and other devices on the network, such as a router. Encrypted connections and careful certificate verification can help prevent MITM attacks.

It then covers topics like mobile threat modeling, mobile application auditing techniques including dynamic and static analysis. The document also discusses the OWASP top 10 mobile risks and provides case studies and demonstrations on pentesting real mobile applications and reverse engineering Android malware.
Talking About SSRF,CRLF
The document discusses CRLF injection and SSRF vulnerabilities. CRLF injection occurs when user input is directly parsed into response headers without sanitization, allowing special characters to be injected. SSRF is when a server is induced to make HTTP requests to domains of an attacker's choosing, potentially escalating access. Mitigations include sanitizing user input, implementing whitelists for allowed domains/protocols, and input validation.
Domain name system (dns)
The document discusses the Domain Name System (DNS) and how it works. DNS is an internet directory service that maps hostnames to IP addresses, allowing users to use names instead of numbers. It uses a distributed, hierarchical system of name servers to perform this name resolution in a scalable way. DNS caches mappings for performance, starting queries at the highest level domains and following delegations between servers until the answer is found. DNS has become a major attack vector, so protection of DNS infrastructure and traffic is important.

OSI Layer Security
This document summarizes a seminar on computer network security given on November 22, 2012. It discusses the OSI model layers and security perspectives for each layer. The layers covered are the physical, data link, network, transport, session, presentation, and application layers. Common attacks are listed for each layer such as packet sniffing for the data link layer and SQL injection for the application layer. The document concludes with a reminder that social engineering is also an important security issue.
IdP, SAML, OAuth
IdP, SAML, OAuth are new acronyms for identity in the cloud. SAML is used for federated authentication between an identity provider (IdP) like Active Directory and a service provider (SP) like Office 365. The IdP authenticates the user and sends a SAML token with claims to the SP. OAuth streamlines authentication for mobile by issuing short-lived access tokens instead of passing full credentials or SAML assertions between each service. It allows authorization without passwords and tokens can be revoked, reducing risks of compromised apps. Office 365 uses Azure Active Directory as an IdP with SAML or OAuth to authenticate users from an on-premises Active Directory via federation or synchronization.

HTTP Adaptive Streaming – Quo Vadis (2024)
Video traffic on the Internet is constantly growing; networked multimedia applications consume a predominant share of the available Internet bandwidth. A major technical breakthrough and enabler in multimedia systems research and of industrial networked multimedia services certainly was the HTTP Adaptive Streaming (HAS) technique. This resulted in the standardization of MPEG Dynamic Adaptive Streaming over HTTP (MPEG-DASH) which, together with HTTP Live Streaming (HLS), is widely used for multimedia delivery in today’s networks. Existing challenges in multimedia systems research deal with the trade-off between (i) the ever-increasing content complexity, (ii) various requirements with respect to time (most importantly, latency), and (iii) quality of experience (QoE). Optimizing towards one aspect usually negatively impacts at least one of the other two aspects if not both. This situation sets the stage for our research work in the ATHENA Christian Doppler (CD) Laboratory (Adaptive Streaming over HTTP and Emerging Networked Multimedia Services; https://athena.itec.aau.at/), jointly funded by public sources and industry. In this talk, we will present selected novel approaches and research results of the first year of the ATHENA CD Lab’s operation. We will highlight HAS-related research on (i) multimedia content provisioning (machine learning for video encoding); (ii) multimedia content delivery (support of edge processing and virtualized network functions for video networking); (iii) multimedia content consumption and end-to-end aspects (player-triggered segment retransmissions to improve video playout quality); and (iv) novel QoE investigations (adaptive point cloud streaming). We will also put the work into the context of international multimedia systems research.

Quality Patents: Patents That Stand the Test of Time
Is your patent a vanity piece of paper for your office wall? Or is it a reliable, defendable, assertable, property right? The difference is often quality.
Is your patent simply a transactional cost and a large pile of legal bills for your startup? Or is it a leverageable asset worthy of attracting precious investment dollars, worth its cost in multiples of valuation? The difference is often quality.
Is your patent application only good enough to get through the examination process? Or has it been crafted to stand the tests of time and varied audiences if you later need to assert that document against an infringer, find yourself litigating with it in an Article 3 Court at the hands of a judge and jury, God forbid, end up having to defend its validity at the PTAB, or even needing to use it to block pirated imports at the International Trade Commission? The difference is often quality.
Quality will be our focus for a good chunk of the remainder of this season. What goes into a quality patent, and where possible, how do you get it without breaking the bank?
** Episode Overview **
In this first episode of our quality series, Kristen Hansen and the panel discuss:
⦿ What do we mean when we say patent quality?
⦿ Why is patent quality important?
⦿ How to balance quality and budget
⦿ The importance of searching, continuations, and draftsperson domain expertise
⦿ Very practical tips, tricks, examples, and Kristen’s Musts for drafting quality applications

Mdk3 tool in kali linux
- 1. Mdk3 Tool in Kali Linux Presented by: Muhammad Zohaib Shah Khagga
- 2. Introduction • MDK3 stands for Murder Death Kill 3. • MDK is a proof-of-concept tool to exploit common IEEE 802.11 protocol weaknesses. • It is your responsibility to make sure you have permission from the network owner before running MDK against it.
- 3. Getting started with mdk3 • As a prerequisite, make sure your wireless adapter is in packet injecting mode, otherwise this won’t work right at all. • To put the wifi adapter into packet injecting mode use the syntax below to get an idea: • “airmon-ng start <wireless interface>” • You can get help by typing “mdk3 –fullhelp”
- 4. Mdk3 Purposes.. • SSID Flooding with Mdk3 • Authentication Flooding with mdk3 • De-authentication Flooding with mdk3
- 5. SSID Flooding with Mdk3 • One neat trick that MDK3 can do is SSID flooding, or beacon flooding • MDK3 can broadcast hundreds or even thousands of fake access points • SSID flooding is not denial of service • You could, in effect, hide your legitimate wireless access point in a sea of fake access points
- 6. 1. SSID Flooding with Mdk3 cont… • Here is the syntax to enable simple SSID flooding (MDK3 will generate random fake access point names) • “mdk3 <interface> b -c 1” • Just replace <interface> with the name of your wireless interface. Remember, usually it’s mon0 • The b option tells MDK3 to use beacon/SSID flooding mode • -c1 tells MDK3 to broadcast all the fake access points on channel 1
- 7. 2. Authentication Flooding with Mdk3 • The idea behind authentication flooding is simple • Too many authentication requests at one time may cause the wireless access point to freeze up and perhaps stop working entirely • Authentication flooding doesn’t always work • A simple command to do authentication flooding is: “mdk3 <interface> a -a <ap_mac address>”
- 8. 2. Authentication Flooding with Mdk3 cont… • All you need is the AP’s(Access Point) MAC address • a Authentication DoS mode (Send authentication frames to all APs found in range) • -a <ap_mac address> (You need the access point’s MAC address, which can be obtained with airodump) • -m (Use a valid client MAC from OUI database)
- 9. 2. Authentication Flooding with Mdk3 cont… • -c (Don’t check that the test was successful, just run the attack) • -i <ap_mac> (Performs an intelligent test on the access point (-a and -c will be ignored). This test connects clients to the AP and reinjects sniffed data to keep them alive) • -s <pps> (Sets the speed in packets per second)
- 10. 3. De-Authentication Flooding with Mdk3 • The DoS WiFi hacking technique that works best uses deauthenticate requests rather than faking authentication requests • “mdk3 <interface> d -b blacklist_file” • The only thing you need is the target access point’s MAC address. Save that MAC address in a text file and specify it after the -b option
- 11. 3. De-Authentication Flooding with Mdk3 cont… • d – Deauthentication / Disassociation Amok Mode Kicks everybody found from AP • -w <filename> Read file containing MAC addresses to ignore (Whitelist mode) • -b <filename> Read from a file containing MAC addresses to attack (Blacklist Mode) • -s <pps> Set the speed in packets per second (Default: unlimited) • -c [chan,chan,chan,...] Enables channel hopping. Without providing any channels, mdk3 will hop all channels until it finds the target you specified
- 12. Refrences • http://ironkali.blogspot.com/2014/03/tutorial-how- to-ddos-wifi-with-mdk3.html • https://tools.kali.org/wireless-attacks/mdk3 • https://svn.mdk3.aircrack- ng.org/mdk3/docs/Documentation_incomplete.html
