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.

  • Solution Brief Recovering from Ransomware with Barracuda Backup
    Solution Brief Recovering from Ransomware with Barracuda Backup Ransomware is a malware variant that locks an end user’s computer or encrypts their files, then demands a sum of money to allow access or decryption. What’s worse, if an organization hands over the cash, there are often times when the attacker doesn’t play nice and still withholds the key even after payment. Ransomware is problematic for businesses because it not only results in financial loss, but also tainted credibility and lost productivity. However, this situation can be avoided if your organization has taken the steps to implement a ransomware prevention plan. In this solution brief, we will discuss some of the steps you can take to prevent ransomware attacks, as well as how to quickly recover from them using Barracuda Backup. Introduction Due to the sophistication of today’s threat landscape, ransomware can be difficult to catch right at the door. Once this malicious malware crosses the threshold, a business user is hit by a daunting message, informing the user that their computer and files have been seized, and payment is required. What’s equally perturbing is that ransomware doesn’t discriminate—it can happen to the mom and pop shops to large enterprises. It’s not a matter of if a business will get hit, but when. Protecting Your Organization from Ransomware Attackers have created many different variations of ransomware over the past few years, such as CryptoLocker, CryptoWall, TorrentLocker, TeslaCrypt, Locky, Petya, WannaCry, Bad Rabbit, and Samas. Each of these variations use new methods of infecting their victims’ computers, thereby compromising the data and network of many organizations worldwide.

  • Trojans and Malware on the Internet an Update
    Attitude Adjustment: Trojans and Malware on the Internet An Update Sarah Gordon and David Chess IBM Thomas J. Watson Research Center Yorktown Heights, NY Abstract This paper continues our examination of Trojan horses on the Internet; their prevalence, technical structure and impact. It explores the type and scope of threats encountered on the Internet - throughout history until today. It examines user attitudes and considers ways in which those attitudes can actively affect your organization’s vulnerability to Trojanizations of various types. It discusses the status of hostile active content on the Internet, including threats from Java and ActiveX, and re-examines the impact of these types of threats to Internet users in the real world. Observations related to the role of the antivirus industry in solving the problem are considered. Throughout the paper, technical and policy based strategies for minimizing the risk of damage from various types of Trojan horses on the Internet are presented This paper represents an update and summary of our research from Where There's Smoke There's Mirrors: The Truth About Trojan Horses on the Internet, presented at the Eighth International Virus Bulletin Conference in Munich Germany, October 1998, and Attitude Adjustment: Trojans and Malware on the Internet, presented at the European Institute for Computer Antivirus Research in Aalborg, Denmark, March 1999. Significant portions of those works are included here in original form. Descriptors: fidonet, internet, password stealing trojan, trojanized system, trojanized application, user behavior, java, activex, security policy, trojan horse, computer virus Attitude Adjustment: Trojans and Malware on the Internet Trojans On the Internet… Ever since the city of Troy was sacked by way of the apparently innocuous but ultimately deadly Trojan horse, the term has been used to talk about something that appears to be beneficial, but which hides an attack within.

  • (Malicious Software) Installed on Your Computer Without Your Consent to Monitor Or Control Your Computer Use
    Spyware is a type of malware (malicious software) installed on your computer without your consent to monitor or control your computer use. Clues that spyware is on a computer may include a barrage of pop-ups, a browser that takes you to sites you don't want, unexpected toolbars or icons on your computer screen, keys that don't work, random error messages, and sluggish performance when opening programs or saving files. In some cases, there may be no symptoms at all. While the term spyware suggests that software that secretly monitors the user's computing, the functions of spyware extend well beyond simple monitoring. Spyware programs can: Collect information stored on the computer or attached network drives, Collect various types of personal information, such as Internet surfing habits, sites that have been visited Collect user names and passwords stored on your computer as well as those entered from the keyboard. Interfere with user control of the computer Install additional software on the computer Redirect Web browser activity. Change computer settings, resulting in slow connection speeds, different home pages, and/or loss of Internet or functionality of other programs. The best defense against spyware and other unwanted software is not to download it in the first place. Here are a few helpful tips that can protect you from downloading software you don't want: Update your operating system and Web browser software, and set your browser security high enough to detect unauthorized downloads. Use anti-virus and anti-spyware, as well as a firewall software, and update them all regularly.

  • Detecting Malware in TLS Traffic
    IMPERIAL COLLEGE LONDON DEPARTMENT OF COMPUTING Detecting Malware in TLS Traffic Project Report Supervisor: Author: Sergio Maffeis Olivier Roques Co-Supervisor: Marco Cova Submitted in partial fulfillment of the requirements for the MSc degree in Computing Science / Security and Reliability of Imperial College London September 2019 Abstract The use of encryption on the Internet has spread rapidly these last years, a trend encouraged by the growing concerns about online privacy. TLS (Transport Layer Security), the standard protocol for packet encryption, is now implemented by every major websites to protect users’ messages, transactions and credentials. However cybercriminals have started to incorporate TLS into their activities. An increasing number of malware leverage TLS encryption to hide their communications and to exfiltrate data to their command server, effectively bypassing traditional detection platforms. The goal of this project is to design and implement an effective alternative to the unpractical method of decrypting TLS packets’ payload before looking for signs of malware activity. This work presents a highly accurate supervised classifier that can detect malicious TLS flows in a company’s network traffic based on a set of features related to TLS, certificates and flow metadata. The classifier was trained on curated datasets of benign and malware observations, which were extracted from capture files thanks to a set of tools specially developed for this purpose. We detail in this report the complete development process, from data collection and feature extraction to model selection and performance analysis. ii Acknowledgments I would like to particularly thank Marco Cova and Sergio Maffeis, my project su- pervisors, for their valuable and continuous suggestions and for their constructive feedbacks on this project.

  • Ransomware and Cyber Risk Management
    Ransomware and Cyber Risk Management By Randy Werner Ransomware and cyber extortion represent one of the more malicious types of hacker attacks making the rounds today. It sneaks into computer systems, encrypts files, and demands a ransom before decrypting the files. A major problem is that ransomware does not always decrypt files even after the ransom is paid. Being prepared and taking precautions against cyber risk exposures such as ransomware is therefore essential. Otherwise, if not prepared, you are at the mercy of criminals who prey on unprepared and unsuspecting businesses and individuals. Ransom demands range from a few hundred dollars to several thousand, depending on the size of the victim. Not all ransomware attacks are reported to authorities, so estimates of the total amount paid over the past few years vary widely, ranging up to $300 million. The more notorious names among ransomware are CryptoLocker, CryptoWall, TorrentLocker and Locky, among others. Some attacks rely on software that now has known fixes, so a solution might be found online. However, other ransomware is technically advanced and has no known fix, except for the victim to rely on current backup files. The primary defense is to institute frequent backups of the files you do not want to lose. Some ransomware even seeks out backup copies of files, so best practices include creating multiple backups in different locations. Cloud services, or remote backup services, and external or USB hard drives are options to consider for multiple backups. Even with backup files in place, a firm may still spend many hours gathering, re-entering and reconstructing data.
