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. -

Security Now! #664 - 05-22-18 Spectreng Revealed
Security Now! #664 - 05-22-18 SpectreNG Revealed This week on Security Now! This week we examine the recent flaws discovered in the secure Signal messaging app for desktops, the rise in DNS router hijacking, another seriously flawed consumer router family, Microsoft Spectre patches for Win10's April 2018 feature update, the threat of voice assistant spoofing attacks, the evolving security of HTTP, still more new trouble with GPON routers, Facebook's Android app mistake, BMW's 14 security flaws and some fun miscellany. Then we examine the news of the next-generation of Spectre processor speculation flaws and what they mean for us. Our Picture of the Week Security News Update your Signal Desktop Apps for Windows & Linux A few weeks ago, Argentinian security researchers discovered a severe vulnerability in the Signal messaging app for Windows and Linux desktops that allows remote attackers to execute malicious code on recipient systems simply by sending a message—without requiring any user interaction. The vulnerability was accidentally discovered while researchers–amond them Juliano Rizzo–were chatting on Signal messenger and one of them shared a link of a vulnerable site with an XSS payload in its URL. However, the XSS payload unexpectedly got executed on the Signal desktop app!! (Juliano Rizzo was on the beach when the BEAST and CRIME attacks occurred to him.) After analyzing the scope of this issue by testing multiple XSS payloads, they found that the vulnerability resides in the function responsible for handling shared links, allowing attackers to inject user-defined HTML/JavaScript code via iFrame, image, video and audio tags. -

As we create and expand more and more data within our interconnected electronic universe, the threat that they bring to its fragile structure grows as well. However Anonymous is not the only group of hackers/activists or hacktivists that have made their presence known. LulzSec was a group that wreaked havoc with information systems in 2011. This will be a case study examination of their activities so that a better understanding of five aspects can be obtained: the Timeline of activities, the Targets of attack, the Tactics the group used, the makeup of the Team and a category which will be referred to as The Twist for reasons which will be made clear at the end of the paper. Keywords: LulzSec, Hackers, Security, AntiSec, Anonymous, Sabu INTRODUCTION Information systems lie at the heart of our modern existence. We deal with them when we work, when we play and when we relax; texting, checking email, posting on Facebook, Tweeting, gaming, conducting e-commerce and e- banking have become so commonplace as to be nearly invisible in modern life. Yet, within each of these electronic interactions lies the danger that the perceived line of security and privacy might be breached and our most important information and secrets might be revealed and exploited. -
Attacking from Inside
WIPER MALWARE: ATTACKING FROM INSIDE Why some attackers are choosing to get in, delete files, and get out, rather than try to reap financial benefit from their malware. AUTHORED BY VITOR VENTURA WITH CONTRIBUTIONS FROM MARTIN LEE EXECUTIVE SUMMARY from system impact. Some wipers will destroy systems, but not necessarily the data. On the In a digital era when everything and everyone other hand, there are wipers that will destroy is connected, malicious actors have the perfect data, but will not affect the systems. One cannot space to perform their activities. During the past determine which kind has the biggest impact, few years, organizations have suffered several because those impacts are specific to each kinds of attacks that arrived in many shapes organization and the specific context in which and forms. But none have been more impactful the attack occurs. However, an attacker with the than wiper attacks. Attackers who deploy wiper capability to perform one could perform the other. malware have a singular purpose of destroying or disrupting systems and/or data. The defense against these attacks often falls back to the basics. By having certain Unlike malware that holds data for ransom protections in place — a tested cyber security (ransomware), when a malicious actor decides incident response plan, a risk-based patch to use a wiper in their activities, there is no management program, a tested and cyber direct financial motivation. For businesses, this security-aware business continuity plan, often is the worst kind of attack, since there is and network and user segmentation on top no expectation of data recovery. -
Ransomware Is Here: What You Can Do About It?
WHITEPAPER Ransomware is Here: What you can do about it? Overview Over the last few years, ransomware has emerged as one of the most devastating and costly attacks in the hacker arsenal. Cyber thieves are increasingly using this form of attack to target individuals, corporate entities and public sector organizations alike by holding your system or files for ransom. Unlike other forms of cyber theft that often involve stolen financial or healthcare information, ransomware cuts out the middleman. In cases where an attacker steals health or financial documents, they must sell them on to third parties to make money. As far as ransomware is concerned, the money comes directly from the victim. Ransomware is a quickly growing threat vector. According to the FBI’s Internet Crime Complaint center (IC3), infected users made complaints about ransomware 2,453 times in 2015—nearly double the figure for 2014. What’s more, these figures most likely represent only the tip of the iceberg, as many users pay their ransom without making a report to the authorities. A recent survey conducted by a Cyber Security Research Center at the University of Kent found that over 40% of those infected with CryptoLocker actually agreed to pay the ransom demanded, which is a big incentive for hackers to target more systems. Lastly, hackers are rapidly iterating both malware and distribution techniques. In early Q2 of 2016, a new variant of ransomware, known as CryptXXX, emerged on the scene. This program is packed in such a way that users and antivirus software may initially confuse it for a Windows DLL file. -

Westlaw Journal BANK & LENDER LIABILITY Litigation News and Analysis • Legislation • Regulation • Expert Commentary VOLUME 17, ISSUE 6 / AUGUST 1, 2011 Expert Analysis Once More Into the Breach: Are We Learning Anything? By Cynthia Larose, Esq. Mintz Levin Cohn Ferris Glovsky & Popeo I’m a guy who doesn’t see anything good having come from the Internet. … [The Internet] created this notion that anyone can have whatever they want at any given time. It’s as if the stores on Madison Avenue were open 24 hours a day. They feel entitled. They say, “Give it to me now,” and if you don’t give it to them for free, they’ll steal it. –Sony Pictures Entertainment CEO Michael Lynton, May 14, 20091 How ironic. This comment two years ago by Lynton created a minor firestorm and drove him to post a lengthy rebuttal on The Huffington Post,2 but at the time, Lynton was referring to content piracy, not data breaches. Given the events since Sony’s massive data breaches in April3 (and subsequent breaches in May and June), he might as well as have been referring to user informa- tion held by Sony and its various properties. As a matter of fact, the Sony Pictures hackers said, “Sony stored over 1 million passwords of its customers in plain text, which means it’s just a matter of taking it.”4 Since the April PlayStation Network breach that exposed more than 100 million user accounts, Sony has been hacked more than 10 times. Sony Europe,5 Sony BMG Greece,6 Sony Thailand,7 Sony Music Japan8 and Sony Ericsson Canada9 all suffered some intrusion and compromise of user information. -
FSRM : Protéger Son Serveur De Fichiers Des Ransomwares Jeudi 20 Avril 2017 16:33

Configurer le SMTP pour recevoir les notifications • IV. Création d’un groupe d’extensions de fichiers • V. Créer un modèle de filtre de fichiers • VI. Créer un filtre de fichiers • VII. Test de la configuration • VIII. Pour aller plus loin I. 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 ». -

At the same time, it has resulted in an increase in cybersecurity risks due to the lack of security for IoT devices. IoT botnets, for instance, have become a critical threat; however, systematic and comprehensive studies analyzing the importance of botnet detection methods are limited in the IoT environment. Thus, this study aimed to identify, assess and provide a thoroughly review of experimental works on the research relevant to the detection of IoT botnets. To accomplish this goal, a systematic literature review (SLR), an effective method, was applied for gathering and critically reviewing research papers. This work employed three research questions on the detection methods used to detect IoT botnets, the botnet phases and the different malicious activity scenarios. The authors analyzed the nominated research and the key methods related to them. The detection Citation: Wazzan, M.; Algazzawi, D.; methods have been classified based on the techniques used, and the authors investigated the botnet Bamasaq, O.; Albeshri, A.; Cheng, L. -
