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. -

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. -
