Implementation and Analysis of Key Reinstallation Attack
International Journal of Innovations in Engineering and Technology (IJIET) http://dx.doi.org/10.21172/ijiet.133.21 Implementation and Analysis of Key Reinstallation Attack Saba Khanum1, Ishita kalra2 1Department of Information Technology, MSIT, Janakpuri, New Delhi, India 2Department of Computer Science and Engineering, MSIT, Janakpuri, New Delhi, India Abstract- The objective of the paper is to implement and analyzed the impact of Key Reinstallation Attack (popularly dubbed as KRACK) on debian based machines. The paper elucidates on the capture of packets through the attack without being a part of the network and affecting the target machines with the help of an attack machine placed inside the network. It basically exploits the nonce of the network which ultimately paves way to the execution of the attack. The issue tends to gather more eyeballs as it affects all devices using Wi-Fi through WPA2 protocol. Hence, the catastrophe complimented along the attack is severe. The analysis of the impact is carried on by analyzing the type of packets visible as well as captured during the course of the implementation. Here, we have created a python script which identifies whether the targeted machine is vulnerable to KRACK or not and corresponding to that the packet capture starts and ultimately, the impact is measured. Keywords – KRACK, weakness, WPA2, attack, security I. INTRODUCTION The presence of the bug has been detected in the cryptographic nonce of the WPA2 and can be used to clone a connected party to reinstall a used key. The presence of the nonce is specifically intended to prevent reuse, but in this particular case, it gives malicious users the opportunity to replay, decrypt, or forge packets, ultimately enabling them to access all previously considered encrypted information without actually being part of the network.

Here's What You Need to Know About KRACK, the Worst Cyber Threat Yet What Is KRACK? Who's on KRACK and What Can Be Done?
Here’s What You Need to Know About KRACK, the Worst Cyber Threat Yet November 2, 2017 by Jim Akin Chances are, you’ve got passwords to at least a handful of Wi-Fi networks saved on your smartphone, tablet and laptop. Most of us do, because wireless Internet connections are central to most homes and workplaces. That’s why a recently uncovered security vulnerability known as KRACK is so significant. It puts the private data of virtually all Wi-Fi users at risk. Here’s some background on the extent of the issue, and guidelines on what you can do to protect yourself and your data. What is KRACK? KRACK is a clunky acronym for a criminal hacking technique (Key Reinstallation AttaCK) that can expose information shared on Wi-Fi networks, even over connections “secured” with data encryption and passwords. Without delving into the technical specifics, (there’s a good detailed take here if you’re curious), the vulnerability breaks WPA 2, the strongest and most common form of encryption used to protect data on home and business Wi-Fi networks. WPA 2 encryption is designed to maintain private connections so that anyone who hijacks data by “listening in” to a wireless-networking signal without your password (and the permission that implies) receives only unintelligible chunks of information. KRACK can thwart that, exposing credit card numbers, account usernames and passwords, and other private data that could end up on the dark web, for any criminal to abuse. In certain instances, KRACK can even enable crooks to install malicious code on devices and websites.

In fact, in this era, people are connected to the internet almost everyday and wireless networks give us this privilege in a seamless manner. A wireless network normally consists of access points and nodes where the access points are responsible to amplify the wireless signals, while the nodes are the gadgets that are receiving these signals. However, with such great convenience provided, many challenges are also faced by the users and stakeholders. With no physical connection to devices, wireless networks are evidently more vulnerable to invisible cyber attacks. In this research paper, it the security issues that cause issues in the wireless networks are discussed. Furthermore, an analytical review of privacy challenges found in these networks is performed; these challenges are segregated into security issues and privacy issues.

Security Predictions for 2018 Skills and Resources — These Are the Two Elements That Make up an Attacker’S Arsenal
PARADI G M SHI FTS Trend Micro Security Predictions for 2018 Skills and resources — these are the two elements that make up an attacker’s arsenal. An attacker, however, cannot set out to break security or even perform sophisticated attacks without finding weak points in a system first. Massive malware attacks, email-borne heists, hacked devices, and disrupted services — all of these require a vulnerability in the network, whether in the form of technology or people, in order to be pulled off. Increased connectivity and interaction over insecure networks are a given. Unfortunately, poor implementation of technologies adds to the likelihood of threats being realized. Having protection where and when it’s needed will become the backbone of security in this ever-shifting threat landscape. In 2018, digital extortion will be at the core of most cybercriminals’ business model and will propel them into other schemes that will get their hands on potentially hefty payouts. Vulnerabilities in IoT devices will expand the attack surface as devices get further woven into the fabric of smart environments everywhere. Business Email Compromise scams will ensnare more organizations to fork over their money. The age of fake news and cyberpropaganda will persist with old-style cybercriminal techniques. Machine learning and blockchain applications will pose both promises and pitfalls. Companies will face the challenge of keeping up with the directives of the General Data Protection Regulation (GDPR) in time for its enforcement. Not only will enterprises be riddled with vulnerabilities, but loopholes in internal processes will also be abused for production sabotage. These are the threats that will make inroads in the 2018 landscape.
