    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.

    North Korean Cyber Capabilities: In Brief Emma Chanlett-Avery Specialist in Asian Affairs Liana W. Rosen Specialist in International Crime and Narcotics John W. 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.
  • Analysis of the Teslacrypt Family and How to Protect Against Future

    Analysis of the Teslacrypt Family and How to Protect Against Future

    Sophia Wang COMP 116 Final Project Analysis of the TeslaCrypt Family and How to Protect Against Future Ransomware/Cyber Attacks Abstract Ransomware accounts for a large majority of the malicious attacks in the cyber security world, with a company hit with a ransomware attack once every 40 seconds. There was a 300% increase in ransomware attacks from 2015 to 2016 — and it’s only going up from there. One family of Trojan-style ransomware technology that introduced itself in early 2015 is TeslaCrypt. TeslaCrypt affected Windows users from the US, Germany, Spain, Italy, France, and the United Kingdom, targeting mostly gamers. This form of ransomware would encrypt the victim’s files using a highly complicated encryption key and demand $250 to $1,000 for ransom. The creators of TeslaCrypt eventually released the master decryption key in May of 2016, so in the end the victims were able to recover their files and systems. This paper will explore the process by which the TeslaCrypt ransomware infected a system, the steps that were taken to ameliorate this issue, and what steps should be taken to avoid an incident like this in the future. Introduction Ransomware is a special form of malware that can infect a system through either encrypting and denying users access to their files, or restricting access and locking users out of their systems. Once the ransomware has the target’s files and/or system on lock, it demands a ransom be paid, usually through some form of cryptocurrency. In February of 2015, a new family of file-encrypting Trojan-style ransomware technology was introduced — TeslaCrypt.

One of the ways that Ransomware makes its way to end users is through a well-crafted email with an attachment. The attachment is malicious and when you click to download it, the ransomware encrypts (locks) certain types of files (.docx, .pdf, .jpg, etc) stored on local and mounted network drives, such as a server shared drive at the office.

Box 1058 • Black Diamond • Washington • 98010-1058 • USA +1 206 683 5683 • [email protected] www.ostermanresearch.com • @mosterman Executive Summary • Various types of security threats are increasing in number and severity at a rapid pace, most notably cryptojacking malware that is focused on mining coins for the roughly 1,400 cryptocurrencies currently in use. • Organizations have been victimized by a wide range of threats and exploits, most notably phishing attacks that have penetrated corporate defenses, targeted email attacks launched from compromised accounts, and sensitive or confidential information accidentally leaked through email. • Threats are becoming more sophisticated as well-financed cybercriminal gangs develop improved variants of malware and social engineering attacks. The result is that the perceived effectiveness of current security solutions is not improving – or is actually getting worse – for many organizations. • Decision makers are most concerned about endpoints getting infected with malware through email or web browsing, user credentials being stolen through email-based phishing, and senior executives’ credentials being stolen through email-based spearphishing. • Four of the five leading concerns expressed by decision makers focus on email as the primary threat vector for cybercriminal activity, and nearly one-half of attacks are focused on account takeovers. Many organizations • Most decision makers have little confidence that their security infrastructure can adequately address infections on mobile devices, are not CEO Fraud/BEC, and preventing users personal devices from introducing malware into the corporate network.

    Gothic Panda Possibly Used Doublepulsar a Year Before The

    Memo 17/05/2019 - TLP:WHITE Gothic Panda possibly used DoublePulsar a year before the Shadow Brokers leak Reference: Memo [190517-1] Date: 17/05/2019 - Version: 1.0 Keywords: APT, DoublePulsar, China, US, Equation Group Sources: Publicly available sources Key Points Gothic Panda may have used an Equation Group tool at least one year before the Shadow Brokers leak. It is unknown how the threat group obtained the tool. This is a good example of a threat actor re-using cyber weapons that were originally fielded by another group. Summary According research conducted by Symantec, the Chinese threat actor known as Gothic Panda (APT3, UPS, SSL Beast, Clandestine Fox, Pirpi, TG-0110, Buckeye, G0022, APT3) had access to at least one NSA-associated Equation Group tool a year before they were leaked by the Shadow Brokers threat actor. On April 14, 2017, a threat actor called the Shadow Brokers released a bundle of cyber-attack tools purportedly coming from the US NSA, also referred to as the Equation Group. Among the released material there was the DoublePulsar backdoor implant tool, which was used alongside EternalBlue in the May 2017 destructive WannaCry attack. DoublePulsar is a memory-based kernel malware that allows perpetrators to run arbitrary shellcode payloads on the target system. It does not write anything on the hard drive and will thus disappear once the victim machine is rebooted. Its only purpose is to enable dropping other malware or executables in the system. According to Symantec, Gothic Panda used the DoublePulsar exploit as early as in 2016, a full year before the Shadow Brokers release.

    Reporting, and General Mentions Seem to Be in Decline

    CYBER THREAT ANALYSIS Return to Normalcy: False Flags and the Decline of International Hacktivism By Insikt Group® CTA-2019-0821 CYBER THREAT ANALYSIS Groups with the trappings of hacktivism have recently dumped Russian and Iranian state security organization records online, although neither have proclaimed themselves to be hacktivists. In addition, hacktivism has taken a back seat in news reporting, and general mentions seem to be in decline. Insikt Group utilized the Recorded FutureⓇ Platform and reports of historical hacktivism events to analyze the shifting targets and players in the hacktivism space. The target audience of this research includes security practitioners whose enterprises may be targets for hacktivism. Executive Summary Hacktivism often brings to mind a loose collective of individuals globally that band together to achieve a common goal. However, Insikt Group research demonstrates that this is a misleading assumption; the hacktivist landscape has consistently included actors reacting to regional events, and has also involved states operating under the guise of hacktivism to achieve geopolitical goals. In the last 10 years, the number of large-scale, international hacking operations most commonly associated with hacktivism has risen astronomically, only to fall off just as dramatically after 2015 and 2016. This constitutes a return to normalcy, in which hacktivist groups are usually small sets of regional actors targeting specific organizations to protest regional events, or nation-state groups operating under the guise of hacktivism. Attack vectors used by hacktivist groups have remained largely consistent from 2010 to 2019, and tooling has assisted actors to conduct larger-scale attacks. However, company defenses have also become significantly better in the last decade, which has likely contributed to the decline in successful hacktivist operations.

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.

    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.
