Effective Crypto Ransomawre Detection Using Hardware
Effective Crypto Ransomawre Detection Using Hardware Performance Counters John Podolanko Department of Computer Science & Engineering The University of Texas at Arlington Supervisor Jiang Ming, PhD In partial fulfillment of the requirements for the degree of Master of Science in Computer Science May 2019 Abstract Systems affected by malware in the past 10 years has risen from 29 million to 780 million, which tells us it is a rapidly growing threat. Viruses, ransomware, worms, backdoors, botnets, etc. all come un- der malware. Ransomware alone is predicted to cost $11.5 billion in 2019. As the downtime, data loss, and financial damages are ris- ing, researchers continue to look for new ways to mitigate this threat. However, the common approaches have shown to yield high false posi- tive rates or delayed detection rates resulting in data loss. My research explores a dynamic approach for early-stage ransomware detection by modeling its behavior using hardware performance counters with low overhead. The analysis begins on a bare-metal machine running ran- somware which is profiled for hardware calls using Intel R VTuneTM Amplifier before it compromises the system. By using this approach, I am able to generate models using hardware performance counters extracted by VTuneTM on known ransomware samples collected from VirusTotal and Hybrid Analysis, and I use that data to train the de- tection system using machine learning techniques. I have shown that hardware performance counters can provide effective metrics for use in detecting and mitigating the ever-growing ransomware threat faced by the world while ensuring no data is lost. ii Acknowledgements The author thanks the supervisory committee for all their guidance, support, and patience. -

Winter 2016 E-Newsletter
WINTER 2016 E-NEWSLETTER At Digital Mountain we assist our clients with their e-discovery, computer forensics and cybersecurity needs. With increasing encryption usage and the recent news of the government requesting Apple to provide "backdoor" access to iPhones, we chose to theme this E-Newsletter on the impact data encryption has on attorneys, litigation support professionals and investigators. THE SHIFTING LANDSCAPE OF DATA ENCRYPTION TrueCrypt, a free on-the-fly full disk encryption product, was the primary cross-platform solution for practitioners in the electronic discovery and computer forensics sector. Trusted and widely adopted, TrueCrypt’s flexibility to perform either full disk encryption or encrypt a volume on a hard drive was an attractive feature. When TrueCrypt encrypted a volume, a container was created to add files for encryption. As soon as the drive was unmounted, the data was protected. The ability to add a volume to the original container, where any files or the folder structure could be hidden within an encrypted volume, provided an additional benefit to TrueCrypt users. However, that all changed in May 2014 when the anonymous team that developed TrueCrypt decided to retire support for TrueCrypt. The timing of TrueCrypt’s retirement is most often credited to Microsoft’s ending support of Windows XP. The TrueCrypt team warned users that without support for Windows XP, TrueCrypt was vulnerable. Once support for TrueCrypt stopped, trust continued to erode as independent security audits uncovered specific security flaws. In the wake of TrueCrypt’s demise, people were forced to look for other encryption solutions. TrueCrypt’s website offered instructions for users to migrate to BitLocker, a full disk encryption program available in certain editions of Microsoft operating systems beginning with Windows Vista. -
Full-Disk-Encryption Crash-Course
25C3: Full-Disk-Encryption Crash-Course Everything to hide Jürgen Pabel, CISSP Akkaya Consulting GmbH #0 Abstract Crash course for software based Full-Disk-Encryption. The technical architectures of full-disk-encryption solutions for Microsoft Windows and Linux are described. Technological differences between the two open-source projects TrueCrypt and DiskCryptor are explained. A wish-list with new features for these open-source Full-Disk-Encryption offerings wraps things up. Readers should be familiar with general operating system concepts and have some software development experience. #1 Introduction Software based Full-Disk-Encryption (¹FDEª) solutions are usually employed to maintain the confidentiality of data stored on mobile computer systems. The established terminology is ¹data-at-rest protectionª; it implies that data is protected against unauthorized access, even if an adversary possesses the storage media. Therefore, some of the most common risks to data confidentiality are addressed: loss and theft of mobile computer systems. The encryption and decryption of data is completely transparent to computer users, which makes Full-Disk- Encryption solutions trivial to use. The only user interaction occurs in the Pre-Boot-Authentication (¹PBAª) environment, in which the computer user provides the cryptographic key in order to allow for the operating system to be started and data to be accessed. #2 Architecture I: Pre-Boot-Authentication The Pre-Boot-Authentication environment is loaded before the operating system when the computer is powered-on. The primary purpose of the Pre-Boot-Authentication is to load the encryption key into memory and to initiate the boot process of the installed operating system. -
Advanced Notification of Cyber Threats Against Mamba Ransomware
Advanced Notification of Cyber Threats against Mamba Ransomware Security Advisory AE-Advisory 17-42 Criticality Critical Advisory Released On 13 August 2017 Impact Mamba ransomware fully encrypts the hard drive of an infected machine. Solution Adhere the advices written under the solution section. Affected Platforms Windows Operating System (OS) Summary As the leading trusted secure cyber coordination center in the region, aeCERT has researched and found about a ransomware that is new to the region currently named as “Mamba Ransomware”. Mamba ransomware uses DiskCryptor to encrypt the disks by using a very strong full disk encryption method. The hacker uses psexec utility to gain access to the network and infect the machine with the malware. The malware goes deep into the system to gain access to all services, forces the machine to restart, then starts to encrypt the disk. Advisory Details Mamba ransomware’s initial distribution is similar to other ransomware-type viruses, such as WannaCrypt and Petya. Furthermore, Mamba is used against corporations and organizations. The attacker uses Mamba ransomware to encrypt the hard drive of the victim’s machine. This ransomware uses a legitimate utility called DiskCryptor to achieve full disk encryption of the infected machine on the Master Boot Record level. In order to decrypt the machine, the victim is asked to contact the attacker for the decryption of the hard drive. This group of attackers need to gain access to the network of the company by using psexec utility to run the ransomware on the victim’s machine. The exploit generates a password for DiskCryptor utility. -

DPR Sidoklumpuk Sidoarjo [email protected] Abstrak Cloud Storage memberikan beberapa kemudahan dalam sentralisasi penyimpanan data. Cloud Storage merupakan media penyimpanan yang di dalam pengaksesannya memerlukan jaringan internet. File dan data disimpan di komputer dimana user harus membuat akun Cloud Storage terlebih dahulu. Sebagai langkah kemudahan dalam mengakses data dalam sebuah instansi maka dibutuhkan strategi sentralisasi data yang dapat diakses dan berbagi file atau data bersama dengan biaya lebih murah. Private Cloud Storage bisa dicapai dengan mengimplementasikan Framework ownCloud berbasis Open Source. Penelitian ini bertujuan untuk mengembangkan teknologi penyimpanan data secara terpusat yang memungkinkan user bisa berbagi file atau data bersama. Kata Kunci: Cloud Storage, ownCloud, Private Cloud Storage, Open Source 1. PENDAHULUAN Perkembangan teknologi saat ini mengalami perubahan yang sangat pesat. Hal ini mempengaruhi perkembangan media penyimpanan pada komputer dari masa ke masa. Salah satu jenis berkembangannya adalah media penyimpanan berbasis cloud (awan). Cloud (awan) adalah metafora dari internet, sebagaimana awan yang sering digambarkan di diagram jaringan komputer. Menurut makalah tahun 2008 yang dipublikasikan IEEE Internet Computing, Cloud Computing merupakan suatu paradigma dimana informasi secara permanen tersimpan di server intenet dan tersimpan secara sementara di computer pengguna (client) termasuk di dalamnya desktop, komputer, tablet, notebook dan lain- lain.
