Analysing Ransomware
Ransomware has evolved significantly since 2012, starting as police messages and becoming increasingly sophisticated with encryption and evasion techniques. Ransomware distributors now offer ransomware-as-a-service and use affiliate programs to spread malware via phishing emails and drive-by downloads. Victims' files are encrypted with strong encryption keys while private keys remain with criminal operators, who demand ransom payments in cryptocurrency. Effective defenses include education, backups, layered protection, network segmentation, and application control to limit the impact of ransomware attacks.
Ransomware Attack.pptx
Ransomware is a type of malware that restricts access to an infected computer system until a ransom is paid. It has evolved since its origins in the late 1980s. There are two main types: locker ransomware that denies access to the computer, and crypto ransomware that encrypts files until ransom is paid. Notable ransomware variants include Reveton from 2012, CryptoLocker from 2013, and TorrentLocker and KeRanger from 2014 and 2016 respectively. Ransomware works by encrypting files using public key cryptography. People can help prevent infection by keeping software updated, using antivirus software, backing up files, and avoiding suspicious email attachments or links. Malwarebytes is an effective tool for
Ransomware by lokesh
This document discusses cyber extortion and ransomware. It defines ransomware as malware that locks out a user's system and demands ransom in order to regain access. The document reviews the history of ransomware, describes famous ransomware like Reveton and CryptoLocker, and explains how ransomware works. It provides tips on how to prevent ransomware attacks and instructions for removing malware from Windows PCs.
Wannacry-A Ransomware Attack
WannaCry was a worldwide ransomware attack that occurred in May 2017. It targeted computers running Microsoft Windows by encrypting data and demanding ransom payments in bitcoin. The ransomware spread quickly using NSA hacking tools like EternalBlue and DoublePulsar that exploited Windows vulnerabilities. Over 150 countries and hundreds of thousands of computers were affected. The attack was stopped when a security researcher registered a non-existent domain name that the ransomware was programmed to check with, inadvertently activating a "kill switch."
Ransomware - The Growing Threat
Ransomware has evolved significantly since the AIDS Trojan in 1989. Nowadays, ransomware encrypts users' files and demands ransom payments in cryptocurrency to decrypt them. There are two main types: locker ransomware that denies computer access, and crypto ransomware that encrypts files. Notable ransomware variants discussed include CryptoLocker (2013), Cryptowall (2014), TorrentLocker (2014), KeRanger (2016 Mac), Locky (2016), and the new "ransomware as a service" called Ransom32. Future threats may target infrastructure, cloud services, hardware, and corporate networks. The IC3 has received over $57 million in ransomware damages since 2005, with
What is Ransomware
Ransomware is malware that encrypts a victim's data and demands ransom payment in order to restore access. It typically infiltrates systems through phishing emails or infected websites and exploits existing vulnerabilities. Once installed, it encrypts target data, covers its tracks, and may spread to other devices. Paying the ransom does not guarantee restoration of data and systems. Ransomware is spreading due to readily available malware kits, use of common platforms like JavaScript that enable cross-platform attacks, and ransomware marketplaces that lower the bar for would-be attackers. Organizations can best prevent ransomware by maintaining updated systems with antivirus software, backing up data, and educating users to avoid phishing attempts.
The rise of malware(ransomware)
Hospitals, school districts, state and local governments, law enforcement agencies, small businesses, large businesses—these are just some of the entities impacted recently by ransomware, an insidious type of malware that encrypts, or locks, valuable digital files and demands a ransom to release them. And, of course, home computers are just as susceptible to ransomware, and the loss of access to personal and often irreplaceable items—including family photos, videos, and other data—can be devastating for individuals as well.
seminar report on What is ransomware
Ransomware is a type of malware that encrypts a victim's files and demands ransom payment in order to decrypt the files. The WannaCry attack in 2017 impacted over 300,000 systems in 150 countries through ransomware. While ransomware uses strong encryption, paying the ransom is not recommended as there is no guarantee files will be recovered. It is best to backup files and keep systems updated with the latest security patches to protect against ransomware infections.
Malware analysis
- Malware analysis involves both static and dynamic analysis techniques to understand malware behavior and assess potential damage. Static analysis involves disassembling and reviewing malware code and structure without executing it. Dynamic analysis observes malware behavior when executed in an isolated virtual environment.
- Tools for static analysis include file hashing, string extraction, and PE header examination. Dynamic analysis tools monitor the registry, file system, processes, and network traffic created by malware runtime behavior. These include Process Monitor, Wireshark, Process Explorer, and network sniffers.
- To safely conduct malware analysis, one should create an isolated virtual lab separated from production networks, and install behavioral monitoring and code analysis tools like OllyDbg, Process Monitor, and Wiresh
Introduction to Malware Analysis
This document provides an overview of malware analysis, including both static and dynamic analysis techniques. Static analysis involves examining a file's code and components without executing it, such as identifying file types, checking hashes, and viewing strings. Dynamic analysis involves executing the malware in a controlled environment and monitoring its behavior and any system changes. Dynamic analysis tools discussed include Process Explorer, Process Monitor, and Autoruns to track malware processes, files accessed, and persistence mechanisms. Both static and dynamic analysis are needed to fully understand malware behavior.
Ransomware
Ransomware encrypts personal files on an infected computer and demands payment of a ransom to recover access to the files. Variants like CryptoLocker encrypt files thoroughly while also spreading throughout network shares. Authorities advise against paying ransoms, as it only encourages further criminal behavior. To remove ransomware and prevent future infections, users should use anti-virus software, keep backups of important files offline, and practice safe browsing and networking habits. Regular software updates and limiting administrator privileges also reduces infection risks.

Ransomware is malware that locks devices or encrypts files to extort money in return for access. It is a growing threat for businesses. The document provides 11 steps to prevent ransomware infections, including regularly backing up important data, keeping software updated, training employees, and using security software with features like LiveGrid cloud protection. It also advises what to do if devices are already infected, recommending against paying ransoms.
Ransomware - Impact, Evolution, Prevention
This document discusses ransomware, including its impact, evolution, and prevention. It defines ransomware as malicious software that blocks access to a computer system until a ransom is paid. There are two main types: locker ransomware which locks the system, and crypto ransomware which encrypts files. The document then discusses how ransomware enters systems, how it executes once inside, examples of ransomware strains, and defensive measures like backups and training users.
Ransomware
Cyber extortion is a crime involving an attack or threat of attack against an enterprise, coupled with a demand for money to stop the attack.
Cyber extortions have taken on multiple forms - encrypting data and holding it hostage, stealing data and threatening exposure, and denying access to data.
Malware locks out the user’s system and demands ransom.
Creates “Zombie Computer” operated remotely.
Individuals and business targeted.
This form of extortion works on the assumption that the data is important enough to the user that they are willing to pay for recovery.
There is however no guarantee of actual recovery, even after payment is made.
The first known ransomware was the 1989 "AIDS" trojan (also known as "PC Cyborg") written by Joseph Popp.
Ransomware
The document outlines a presentation about ransomware given by Chase Cunningham, a former NSA cryptologist. The agenda includes discussing the threat landscape of ransomware, how it works through a demo, common mistakes and vulnerabilities, and tips for protecting against it. Examples of recent data breaches and cyber attacks are listed, showing hackers are highly skilled, well-funded, and the threats are growing. Ransomware is malware that locks systems and demands ransom to regain access, and has been very profitable for criminals, though protecting systems requires multilayered security and a secure provider.

Backup is always been the best way to deal with ransomware. Make sure to back up your data in a separate external storage device or you can store your data in the cloud. Use Capebera.com -cloud service to store your data and the best part of the cloud is that it’s not connected to your computer. And in case, your data get encrypted with ransomware threats, you can reboot or reset your system and get back up your data again using Capebera.
Thane Barnier MACE 2016 presentation
This document discusses network security and how attacks have evolved over time. It argues that while firewalls and antivirus software are important, social engineering is the most effective hacking tool as it tricks users into unknowingly compromising security. A strong defense requires educating all users to be wary of potential threats like malicious emails and to serve as the last line of defense through safe password practices and avoiding suspicious file attachments or links. The best protection combines technical security measures with an engaged, informed "cyber militia" of users.
Open Source Malware - Sharing is caring?
This document discusses open source malware and ransomware. It mentions open source projects like HiddenTear and EternalBlue that were later used to create malware like WannaCry. While open sharing can enable education, leaked code from these projects was used by cybercriminals without understanding the technical implications. When code is publicly available, it is difficult to control how it is utilized. There is debate around whether openly sharing such code does more harm than good by unintentionally enabling cyberattacks.
Ransomware all locked up book
Ransomware is a type of malware that encrypts files on an infected device and demands ransom payment to decrypt the files. It works by preying on human emotions like fear of losing important files. For cybercriminals, ransomware is a lucrative business that earned over $24 million from just 2,453 attacks in 2015. There are three main types - encryption ransomware, master boot record ransomware, and lockscreen ransomware. Ransomware poses a big threat to both individuals and businesses alike, though some myths persist that it only targets one group over another. The document discusses whether to pay ransoms or not.
Wanna cry
The document summarizes the WannaCry ransomware attack which infected over 230,000 computers in 150 countries in May 2017. It spread using the EternalBlue exploit to propagate across Windows computers that had not installed the MS17-010 patch. It encrypted files and demanded ransoms between $300-600 paid in bitcoin. A 22-year-old security researcher accidentally stopped the spread by registering a dummy domain name that the ransomware was programmed to check.

Robin van Emden, Senior Director of Data Science at Network Optix, presents the “Building and Scaling AI Applications with the Nx AI Manager,” tutorial at the May 2024 Embedded Vision Summit.
In this presentation, van Emden covers the basics of scaling edge AI solutions using the Nx tool kit. He emphasizes the process of developing AI models and deploying them globally. He also showcases the conversion of AI models and the creation of effective edge AI pipelines, with a focus on pre-processing, model conversion, selecting the appropriate inference engine for the target hardware and post-processing.
van Emden shows how Nx can simplify the developer’s life and facilitate a rapid transition from concept to production-ready applications.He provides valuable insights into developing scalable and efficient edge AI solutions, with a strong focus on practical implementation.Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Ransomware: Wannacry
- 2. Ransomware It is a type of malicious software that will take your important files, encrypt them and then it will blackmailing you to pay for get them back. - this is the new oil, for the bad guys -
- 4. Wannacry ● Affected more than 150 countries. ● Infected major businesses and organizations. ● More than 200,000 systems around the world are believed to be infected Black Friday - May 12, 2017
- 5. Which organizations were affected?
- 7. How much money wannacry ask you? ● Between the first three days = $300 ● Between the next three days (extra chance) = $600 - After seven days without payment, the malware will delete all of the encrypted files and all data will be lost. -
- 8. How does wannacry’s message look like?
- 9. How does it get to you? ● Hosts can get infected downloading for example PDFs or any kind of other files that hide the malware. Normally those are sent via email or accessing to a url. ● Another host in the same network can exploit a vulnerability (SMBv1) and install the malware on it.
- 10. Hard to reach the first one, then easy to reach hundreds... ● NSA leakage on April, 17 2017. ● The Shadow Brokers. ● Some exploits unknown until that time. ● Ethernalblue. SMBv1 (Microsoft Server Message Block 1.0)
- 11. The cure… before the disease Recall, NSA leakage on April 17, 2017 Microsoft solution on March 14, 2017
- 12. Wannacry is using Ethernalblue
- 13. How do prevent it? ● Install the security patch MS17-010. ● Monitor traffic over port 445 in the firewall. ● Block the port 445 (SMBv1) by host. ● Keep your system up-to-date.
