Systematization of Vulnerability Discovery Knowledge: Review
Systematization of Vulnerability Discovery Knowledge Review Protocol Nuthan Munaiah and Andrew Meneely Department of Software Engineering Rochester Institute of Technology Rochester, NY 14623 {nm6061,axmvse}@rit.edu February 12, 2019 1 Introduction As more aspects of our daily lives depend on technology, the software that supports this technology must be secure. We, as users, almost subconsciously assume the software we use to always be available to serve our requests while preserving the confidentiality and integrity of our information. Unfortunately, incidents involving catastrophic software vulnerabilities such as Heartbleed (in OpenSSL), Stagefright (in Android), and EternalBlue (in Windows) have made abundantly clear that software, like other engineered creations, is prone to mistakes. Over the years, Software Engineering, as a discipline, has recognized the potential for engineers to make mistakes and has incorporated processes to prevent such mistakes from becoming exploitable vulnerabilities. Developers leverage a plethora of processes, techniques, and tools such as threat modeling, static and dynamic analyses, unit/integration/fuzz/penetration testing, and code reviews to engineer secure software. These practices, while effective at identifying vulnerabilities in software, are limited in their ability to describe the engineering failures that may have led to the introduction of vulnerabilities. Fortunately, as researchers propose empirically-validated metrics to characterize historical vulnerabilities, the factors that may have led to the introduction of vulnerabilities emerge. Developers must be made aware of these factors to help them proactively consider security implications of the code that they contribute. In other words, we want developers to think like an attacker (i.e. inculcate an attacker mindset) to proactively discover vulnerabilities. -

Compromised Connections
COMPROMISED CONNECTIONS OVERCOMING PRIVACY CHALLENGES OF THE MOBILE INTERNET The Universal Declaration of Human Rights, the International Covenant on Civil and Political Rights, and many other international and regional treaties recognize privacy as a fundamental human right. Privacy A WORLD OF INFORMATION underpins key values such as freedom of expression, freedom of association, and freedom of speech, IN YOUR MOBILE PHONE and it is one of the most important, nuanced and complex fundamental rights of contemporary age. For those of us who care deeply about privacy, safety and security, not only for ourselves but also for our development partners and their missions, we need to think of mobile phones as primary computers As mobile phones have transformed from clunky handheld calling devices to nifty touch-screen rather than just calling devices. We need to keep in mind that, as the storage, functionality, and smartphones loaded with apps and supported by cloud access, the networks these phones rely on capability of mobiles increase, so do the risks to users. have become ubiquitous, ferrying vast amounts of data across invisible spectrums and reaching the Can we address these hidden costs to our digital connections? Fortunately, yes! We recommend: most remote corners of the world. • Adopting device, data, network and application safety measures From a technical point-of-view, today’s phones are actually more like compact mobile computers. They are packed with digital intelligence and capable of processing many of the tasks previously confined -
The Flame: Questions and Answers 1.8
The Flame: Questions and Answers 1.8 Aleks Kaspersky Lab Expert Posted May 28, 13:00 GMT Tags: Targeted Attacks, Wiper, Cyber weapon, Cyber espionage, Flame Duqu and Stuxnet raised the stakes in the cyber battles being fought in the Middle East – but now we’ve found what might be the most sophisticated cyber weapon yet unleashed. The ‘Flame’ cyber espionage worm came to the attention of our experts at Kaspersky Lab after the UN’s International Telecommunication Union came to us for help in finding an unknown piece of malware which was deleting sensitive information across the Middle East. While searching for that code – nicknamed Wiper – we discovered a new malware codenamed Worm.Win32.Flame. Flame shares many characteristics with notorious cyber weapons Duqu and Stuxnet: while its features are different, the geography and careful targeting of attacks coupled with the usage of specific software vulnerabilities seems to put it alongside those familiar ‘superweapons’ currently deployed in the Middle East by unknown perpetrators. Flame can easily be described as one of the most complex threats ever discovered. It’s big and incredibly sophisticated. It pretty much redefines the notion of cyberwar and cyberespionage. For the full lowdown on this advanced threat, read on… General Questions What exactly is Flame? A worm? A backdoor? What does it do? Flame is a sophisticated attack toolkit, which is a lot more complex than Duqu. It is a backdoor, a Trojan, and it has wormlike features, allowing it to replicate in a local network and on removable media if it is commanded so by its master. -

Detecting Botnets Using File System Indicators
Detecting botnets using file system indicators Master's thesis University of Twente Author: Committee members: Peter Wagenaar Prof. Dr. Pieter H. Hartel Dr. Damiano Bolzoni Frank Bernaards LLM (NHTCU) December 12, 2012 Abstract Botnets, large groups of networked zombie computers under centralised control, are recognised as one of the major threats on the internet. There is a lot of research towards ways of detecting botnets, in particular towards detecting Command and Control servers. Most of the research is focused on trying to detect the commands that these servers send to the bots over the network. For this research, we have looked at botnets from a botmaster's perspective. First, we characterise several botnet enhancing techniques using three aspects: resilience, stealth and churn. We see that these enhancements are usually employed in the network communications between the C&C and the bots. This leads us to our second contribution: we propose a new botnet detection method based on the way C&C's are present on the file system. We define a set of file system based indicators and use them to search for C&C's in images of hard disks. We investigate how the aspects resilience, stealth and churn apply to each of the indicators and discuss countermeasures botmasters could take to evade detection. We validate our method by applying it to a test dataset of 94 disk images, 16 of which contain C&C installations, and show that low false positive and false negative ratio's can be achieved. Approaching the botnet detection problem from this angle is novel, which provides a basis for further research. -

Malware Detection Techiniques and Tools for Android Mobile – a Brief Review
International Journal of Latest Research in Engineering and Technology (IJLRET) ISSN: 2454-5031 www.ijlret.com || Volume 03 - Issue 03 || March 2017 || PP. 102-105 Malware Detection Techiniques and Tools for Android Mobile – A Brief Review Dr. Bhaskar V. Patil#1 #1Bharati Vidyapeeth University Yashwantrao Mohite institute of Management, Karad [M.S.], INDIA Dr. Rahul J. Jadhav#2 21Bharati Vidyapeeth University Yashwantrao Mohite institute of Management, Karad [M.S.], INDIA Abstract: Android has the biggest market share among all Smartphone operating system. The number of devices running with the Android operating system has been on the rise. By the end of 2012, it will account for nearly half of the world's Smartphone market. Along with its growth, the importance of security has also risen. Security is one of the main concerns for Smartphone users today. As the power and features of Smartphone’s increase, so has their vulnerability for attacks by viruses etc. Perhaps android is more secured operating system than any other Smartphone operating system today. Android has very few restrictions for developer, increases the security risk for end users. Antivirus Android apps remain one of the most popular types of applications on Android. Some people either like having that extra security or just want to be extra cautious just in case and there is nothing wrong with that. In this list, we’ll check out the best antivirus Android apps and anti-malware apps on Android! The efficacies of these applications have not been empirically established. This paper analyzes some of the security tools written for the Android platform to gauge their effectiveness at mitigating spyware and malware.
