Rollins Specialist in Terrorism and National Security Catherine A. Theohary Specialist in National Security Policy, Cyber and Information Operations August 3, 2017 Congressional Research Service 7-5700 www.crs.gov R44912 North Korean Cyber Capabilities: In Brief Overview As North Korea has accelerated its missile and nuclear programs in spite of international sanctions, Congress and the Trump Administration have elevated North Korea to a top U.S. foreign policy priority. Legislation such as the North Korea Sanctions and Policy Enhancement Act of 2016 (P.L. 114-122) and international sanctions imposed by the United Nations Security Council have focused on North Korea’s WMD and ballistic missile programs and human rights abuses. According to some experts, another threat is emerging from North Korea: an ambitious and well-resourced cyber program. North Korea’s cyberattacks have the potential not only to disrupt international commerce, but to direct resources to its clandestine weapons and delivery system programs, potentially enhancing its ability to evade international sanctions. As Congress addresses the multitude of threats emanating from North Korea, it may need to consider responses to the cyber aspect of North Korea’s repertoire. This would likely involve multiple committees, some of which operate in a classified setting. This report will provide a brief summary of what unclassified open-source reporting has revealed about the secretive program, introduce four case studies in which North Korean operators are suspected of having perpetrated malicious operations, and provide an overview of the international finance messaging service that these hackers may be exploiting.

  • Systematization of Vulnerability Discovery Knowledge: Review
    Systematization of Vulnerability Discovery Knowledge Review Protocol Nuthan Munaiah and Andrew Meneely Department of Software Engineering Rochester Institute of Technology Rochester, NY 14623 {nm6061,axmvse}@rit.edu February 12, 2019 1 Introduction As more aspects of our daily lives depend on technology, the software that supports this technology must be secure. We, as users, almost subconsciously assume the software we use to always be available to serve our requests while preserving the confidentiality and integrity of our information. Unfortunately, incidents involving catastrophic software vulnerabilities such as Heartbleed (in OpenSSL), Stagefright (in Android), and EternalBlue (in Windows) have made abundantly clear that software, like other engineered creations, is prone to mistakes. Over the years, Software Engineering, as a discipline, has recognized the potential for engineers to make mistakes and has incorporated processes to prevent such mistakes from becoming exploitable vulnerabilities. Developers leverage a plethora of processes, techniques, and tools such as threat modeling, static and dynamic analyses, unit/integration/fuzz/penetration testing, and code reviews to engineer secure software. These practices, while effective at identifying vulnerabilities in software, are limited in their ability to describe the engineering failures that may have led to the introduction of vulnerabilities. Fortunately, as researchers propose empirically-validated metrics to characterize historical vulnerabilities, the factors that may have led to the introduction of vulnerabilities emerge. Developers must be made aware of these factors to help them proactively consider security implications of the code that they contribute. In other words, we want developers to think like an attacker (i.e. inculcate an attacker mindset) to proactively discover vulnerabilities.

    DIGITAALISEN KYBERMAAILMAN ILMIÖITÄ JA MÄÄRITTELYJÄ PROF. MARTTI LEHTO V 15.0 6.4.2021 JYVÄSKYLÄN YLIOPISTO INFORMAATIOTEKNOLOGIAN TIEDEKUNTA 2021 ALKUSANAT Euroopan komissio analysoi pohdinta-asiakirjassaan kesällä 2017 tulevaisuuden uhka- maailmaa. Sen mukaan teknologian kehitys muuttaa merkittävästi niin turvallisuuden kuin puolustuksen luonnetta. Big data, pilviteknologia, miehittämättömät ajoneuvot ja tekoäly muokkaavat yhteiskunnan eri rakenteita aina turvallisuuteen ja puolustukseen saakka. Tämän verrattain helposti saatavilla olevan teknologian käyttö mahdollistaa epätavanomaisten, valtioiden rajat ylittävien ja epäsymmetristen uhkien nopean kas- vun. Näitä ovat muun muassa hybridi- ja kyberuhat, terrorismi sekä kemialliset, biologi- set ja radiologiset iskut. Internetin käyttäjien määrän nopean kasvun myötä kyberrikol- lisuus ja terroristien internetin käyttö ovat 2000-luvulla muokanneet merkittävästi digi- taalista toimintaympäristöä.1 Digitaaliteknologia muuttaa ihmisten elämää. EU:n digitaalistrategian tavoitteena on valjastaa digitalisaatio palvelemaan ihmisiä ja yrityksiä sekä tukemaan tavoitetta tehdä Euroopasta ilmastoneutraali vuoteen 2050 mennessä.

    TLP:WHITE The following information is being provided by the FBI, with no guarantees or warranties, for potential use at the sole discretion of 25 AUG 2021 recipients in order to protect against cyber threats. This data is provided to help cyber security professionals and system Alert Number administrators guard against the persistent malicious actions of cyber MC-000150-MW actors. This FLASH was coordinated with DHS-CISA. This FLASH has been released TLP:WHITE. Subject to standard copyright rules, TLP:WHITE information may be distributed without restriction. Indicators of Compromise Associated with Hive Ransomware Summary Hive ransomware, which was first observed in June 2021 and likely operates as an affiliate-based ransomware, employs a wide variety of tactics, techniques, and procedures (TTPs), creating significant challenges for defense and mitigation. Hive ransomware uses multiple mechanisms to compromise business networks, including phishing emails with malicious attachments to gain access and Remote Desktop Protocol (RDP) to move laterally once on the network. After compromising a victim network, Hive ransomware actors exfiltrate data and encrypt files on the network. The actors leave a ransom note in each affected directory within a victim’s system, which provides instructions on how to purchase the decryption software. The ransom note also threatens to leak exfiltrated victim data on the Tor site, “HiveLeaks.” TLP:WHITE TLP:WHITE Technical Details Hive ransomware seeks processes related to backups, anti-virus/anti-spyware, and file copying and terminates them to facilitate file encryption. The encrypted files commonly end with a .hive extension. The Hive ransomware then drops a hive.bat script into the directory, which enforces an execution timeout delay of one second in order to perform cleanup after the encryption is finished by deleting the Hive executable and the hive.bat script.

  • October 28, 2013 CRYPTOLOCKER RANSOMWARE ENCRYPTS USER’S FILES
    October 28, 2013 CRYPTOLOCKER RANSOMWARE ENCRYPTS USER’S FILES The FBI is aware of a file-encrypting Ransomware known as CryptoLocker. Businesses are receiving emails with alleged customer complaints containing attachments that when opened, appear as a window that is in fact a malware downloader. This downloader installs the actual CryptoLocker malware. The verbiage in the window states that important files have been encrypted using a unique public key generated for the computer. To decrypt the files you must obtain the private key. A copy of the private key is located on a remote server that will destroy the key after the specified time shown in the window. The attackers demand payment of a ransom ranging from $100 to $300 to decrypt the files. *Unfortunately, once the encryption of the files is complete, decryption is not feasible. To obtain the file specific Advanced Encryption Standard (AES) key to decrypt a file, you need the private RSA key (an algorithm for public key cryptography) corresponding to the RSA public key generated for the victim’s system by the command and control server. However, this key never leaves the command and control server, putting it out of reach of everyone except the attacker. The recommended solution is to scrub your hard drive and restore encrypted files from a backup. As with any virus or malware, the way to avoid it is with safe browsing and email habits. Specifically, in this case, be wary of email from senders you don’t know, and never open or download an attachment unless you’re sure you know what it is and that it’s safe.
