Ransom Where?
Ransom where? Holding data hostage with ransomware May 2019 Author With the evolution of digitization and increased interconnectivity, the cyberthreat landscape has transformed from merely a security and privacy concern to a danger much more insidious by nature — ransomware. Ransomware is a type of malware that is designed to encrypt, Imani Barnes Analyst 646.572.3930 destroy or shut down networks in exchange [email protected] for a paid ransom. Through the deployment of ransomware, cybercriminals are no longer just seeking to steal credit card information and other sensitive personally identifiable information (PII). Instead, they have upped their games to manipulate organizations into paying large sums of money in exchange for the safe release of their data and control of their systems. While there are some business sectors in which the presence of this cyberexposure is overt, cybercriminals are broadening their scopes of potential victims to include targets of opportunity1 across a multitude of industries. This paper will provide insight into how ransomware evolved as a cyberextortion instrument, identify notorious strains and explain how companies can protect themselves. 1 WIRED. “Meet LockerGoga, the Ransomware Crippling Industrial Firms” March 25, 2019; https://www.wired.com/story/lockergoga-ransomware-crippling-industrial-firms/. 2 Ransom where? | May 2019 A brief history of ransomware The first signs of ransomware appeared in 1989 in the healthcare industry. An attacker used infected floppy disks to encrypt computer files, claiming that the user was in “breach of a licensing agreement,”2 and demanded $189 for a decryption key. While the attempt to extort was unsuccessful, this attack became commonly known as PC Cyborg and set the archetype in motion for future attacks.

Présentation Les données qu’elles soient personnelles ou professionnelles ont une valeur certaine, et ça il y a des personnes malintentionnées qu’ils l’ont bien compris et qui veulent en tirer profit avec des malwares, ou plus particulièrement avec les ransomwares qui sont la grande tendance depuis quelque temps. Pour rappel, un ransomware, en français rançongiciel, est un logiciel qui va chiffrer vos données et vous demander de l’argent pour pouvoir récupérer les données, sous peine de les perdre. Pour se protéger face à cette menace, que l’on peut représenter par Cryptolocker ou plus récemment Locky, il y a différentes couches de sécurité à mettre en place. Tout d’abord, ça passe par une protection au niveau des e-mails avec un filtre anti-spam, du filtrage web pour éviter que les utilisateurs aillent sur des sites où ils n’ont rien à faire, ou encore protéger votre serveur de fichiers, c’est d’ailleurs ce dernier point qui nous intéresse. Dans le cadre de ce tutoriel, il sera question de protéger un serveur de fichiers sous Windows Server 2012 R2 ou sur Windows Server 2008 R2, pour cela on s’appuie sur le File Server Resource Manager (FSRM) , en français « Gestionnaire de ressources du serveur de fichiers ».

Analysis of the Teslacrypt Family and How to Protect Against Future
Sophia Wang COMP 116 Final Project Analysis of the TeslaCrypt Family and How to Protect Against Future Ransomware/Cyber Attacks Abstract Ransomware accounts for a large majority of the malicious attacks in the cyber security world, with a company hit with a ransomware attack once every 40 seconds. There was a 300% increase in ransomware attacks from 2015 to 2016 — and it’s only going up from there. One family of Trojan-style ransomware technology that introduced itself in early 2015 is TeslaCrypt. TeslaCrypt affected Windows users from the US, Germany, Spain, Italy, France, and the United Kingdom, targeting mostly gamers. This form of ransomware would encrypt the victim’s files using a highly complicated encryption key and demand $250 to $1,000 for ransom. The creators of TeslaCrypt eventually released the master decryption key in May of 2016, so in the end the victims were able to recover their files and systems. This paper will explore the process by which the TeslaCrypt ransomware infected a system, the steps that were taken to ameliorate this issue, and what steps should be taken to avoid an incident like this in the future. Introduction Ransomware is a special form of malware that can infect a system through either encrypting and denying users access to their files, or restricting access and locking users out of their systems. Once the ransomware has the target’s files and/or system on lock, it demands a ransom be paid, usually through some form of cryptocurrency. In February of 2015, a new family of file-encrypting Trojan-style ransomware technology was introduced — TeslaCrypt.

There exist indications that PUP prominence has quickly increased over the last years, but the prevalence of PUP on both consumer and enterprise hosts remains unknown. Moreover, many important aspects of PUP such as distribution vectors, code signing abuse, and economics also remain unknown. In this thesis, we empirically and sys- tematically analyze in both breadth and depth PUP abuse, prevalence, distribution, and economics. We make the following four contributions. First, we perform a systematic study on the abuse of Windows Authenticode code signing by PUP and malware.

So, to mitigate the concern issues, massive amount recovery in terms of cost and time for researchers need to come with different approaches and ransomware victims. Previous studies and solutions have showed solutions to defend against current and future threats and also that when it comes to malware detection, malware behavior need to understand the behavior of the malware attacks and their to be prioritized and analyzed in order to recognize malware interactions with victim‟s machine [4]. attack pattern. Although the current state-of-art solutions and frameworks used dynamic analysis approach such as machine The main problem remain persists yet and it still needs to learning that provide more impact rather than static approach, keep on update where the researchers need to understand the but there is not any approachable way in representing the malware behavior whether it is in network traffic or file analysis especially a detection that relies on malware behavior. activity system in the form of statistical and dynamic. This Therefore, this paper proposed a graph theory approach which is research also stressed out the problem in visualizing malware analysis of the ransomware behavior that can be visualized into behavior since the data can be represented in an easy way to be graph-based pattern.

Best Practices to Protect Against Ransomware, Phishing & Email Fraud
WHITE PAPER Best Practices for Protecting Against Phishing, Ransomware and Email Fraud An Osterman Research White Paper Published April 2018 SPON Osterman Research, Inc. P.O. Box 1058 • Black Diamond • Washington • 98010-1058 • USA +1 206 683 5683 • [email protected] www.ostermanresearch.com • @mosterman Executive Summary • Various types of security threats are increasing in number and severity at a rapid pace, most notably cryptojacking malware that is focused on mining coins for the roughly 1,400 cryptocurrencies currently in use. • Organizations have been victimized by a wide range of threats and exploits, most notably phishing attacks that have penetrated corporate defenses, targeted email attacks launched from compromised accounts, and sensitive or confidential information accidentally leaked through email. • Threats are becoming more sophisticated as well-financed cybercriminal gangs develop improved variants of malware and social engineering attacks. The result is that the perceived effectiveness of current security solutions is not improving – or is actually getting worse – for many organizations. • Decision makers are most concerned about endpoints getting infected with malware through email or web browsing, user credentials being stolen through email-based phishing, and senior executives’ credentials being stolen through email-based spearphishing. • Four of the five leading concerns expressed by decision makers focus on email as the primary threat vector for cybercriminal activity, and nearly one-half of attacks are focused on account takeovers. Many organizations • Most decision makers have little confidence that their security infrastructure can adequately address infections on mobile devices, are not CEO Fraud/BEC, and preventing users personal devices from introducing malware into the corporate network.
