Here we have collected some important information about Wanna Cry Ransomware attack. After reading this you will be able to identify this virus.
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 attacks 2017
Ransomware is a type of malicious software that blocks access to data or threatens to publish it until a ransom is paid. Simple ransomware may lock the system in a way which is not difficult for a knowledgeable person to reverse. More advanced malware uses a technique called cryptoviral extortion, in which it encrypts the victim's files, making them inaccessible, and demands a ransom payment to decrypt them and ransomware attacks 2017
How to prevent WannaCry Ransomware
A ransomware cyber-attack that may have originated from the theft of “cyber weapons” linked to the US government has hobbled hospitals in England and spread to countries across the world. "Ransomware is a type of malware that encrypts a user’s data, then demands payment in exchange for unlocking the data. This attack was caused by a bug called “WanaCrypt0r 2.0” or WannaCry, that exploits a vulnerability in Windows. Microsoft released a patch (a software update that fixes the problem) for the flaw in March, but computers that have not installed the security update remain vulnerable."

Ransomware is a type of malware that encrypts files on a computer and demands payment to regain access. It first emerged in 2013 and spread internationally from Russia. There are three main types: encryption ransomware encrypts personal files, lock screen ransomware locks the computer screen until payment is made, and master boot ransomware interrupts the normal boot process. Ransomware typically enters systems through email attachments, compromised online advertisements, or unpatched security vulnerabilities. It can encrypt files and lock access. To protect against ransomware, users should back up files, keep systems updated, use antivirus software, enable firewalls, and install third-party security programs. Being cautious about suspicious links and attachments is key to prevention.
Ransomware hostage rescue manual
Ransomware is a PC or Mac-based malicious piece of software that encrypts a user or company’s files and forces them to pay a fee to the hacker in order to regain access to their own files.
Not only can ransomware encrypt the files on your computer; the software is smart enough to travel across your network and encrypt any files located on shared network drives. This can lead to a catastrophic situation whereby one infected user can bring an entire company to a halt.
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.

WannaCry (WannaCrypt) Ransomware - Advisory from CERT-IN
Wannacry / WannaCrypt ransomware spreads laterally between computers on the same LAN using the ETERNALBLUE exploit of SMB protocol vulnerabilities in Windows systems. It encrypts files on infected systems with various extensions and demands ransom payments in bitcoin. Users and organizations are advised to apply Windows patches, enable firewalls, practice backups, and follow other best practices to prevent infection and data loss from this ransomware.
Flashpoint ransomware april2016
The document summarizes an analysis of an organized Russian ransomware campaign. Key points include:
- The campaign recruited low-level Russian cybercriminals to spread ransomware through phishing emails and compromised servers. The mastermind kept 60% of ransom profits.
- Ransomware was distributed through botnet installs, emails, social media, and file sharing sites. It encrypted victim's files until ransom was paid in Bitcoin.
- On average, the mastermind earned $7,500 per month while affiliates earned $600. Ransoms averaged $300 per US victim. The operation had low perceived risk.
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.
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 the clock is ticking
This document summarizes how ransomware works and has evolved over time. It discusses the results of a recent UK poll showing that 60% of victims had backups but 65% still paid ransoms averaging £540. It then outlines the evolution of ransomware from misleading applications in 2008-2014 to crypto-ransomware beginning in 2013. The document analyzes the social engineering techniques used by ransomware like Locky and CTB-Locker and how they evade filters and antivirus. It compares spam emails to exploit kits and discusses new evasion tricks being used. The document advocates for layered security approaches and outlines minimum protections organizations should implement.
Ransomware: How to avoid a crypto crisis at your IT business
Cryptolocker and other ransomware brought crisis to thousands of businesses last year. The malware made millions by encrypting victims’ files and demanding ransoms to unlock them. Some companies lost everything. Others, including local police departments, had to pay a hefty ransom to recover their data.
Today, Cryptolocker is gone, but ransomware is growing stronger. New variants such as CryptoWall and Critroni are infecting users, locking their files, and demanding higher ransoms. How can you protect your IT business and clients from this growing threat?
Join Calyptix Security for a conversation on crypto-ransomware, where it’s headed, and how to avoid a ‘crypto crisis’ at your office. You’ll get straight-forward advice on how to stop this threat from impacting your business network security and clients.

Ransomware (cyber attack software that holds its targets’ data for ransom) has become an increasing danger to businesses and institutions this year.
This presentation will explore the nature and extent of the problem, legal options for and regulatory obligations of victims of ransomware, and emergent insurance options for dealing with the fallout from ransomware attacks.
What is Ransomware? A Quick Guide
Ransomware is a type of malware that encrypts a victim's files and demands ransom payments in order to regain access. It has become an increasingly common threat, with over 700,000 ransomware attacks occurring between 2015-2016 alone. Ransomware costs victims over £150 million in 2016 in ransom payments. For small and medium businesses, being impacted by ransomware can be costly and disruptive to operations. Experts recommend implementing business continuity solutions such as backups and disaster recovery to prevent ransomware from succeeding in its attacks and holding a business's data hostage.
Ransomware: Mitigation Through Preparation
Ransomware attacks are a growing threat. Zerto provides a virtual replication solution that allows recovery of encrypted files and applications within minutes through continuous replication of changes at the block level. The presentation demonstrated how Zerto can minimize the impact of a ransomware infection by recovering files from seconds before encryption occurred. It also discussed how Zerto helps users prove compliance with regulations by enabling testing and reporting of disaster recovery capabilities.
What is Ransomware?
Ransomware is a hot topic that isn't going away anytime soon. As more strains of this nasty malware are born, it's important to have a clear understanding about what this threat could mean for your business!
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
WHITE PAPER▶ The Evolution of Ransomware
Never before in the history of human kind have people across the world been subjected to extortion on a massive scale as they are today. In recent years, personal use of computers and the internet has exploded and, along with this massive growth, cybercriminals have emerged to feed off this burgeoning market, targeting innocent users with a wide range of malware. The vast majority of these threats are aimed at directly or indirectly making money from the victims. Today, ransomware has emerged as one of the most troublesome malware categories of our time.
There are two basic types of ransomware in circulation. The most common type today is crypto ransomware, which aims to encrypt personal data and files. The other, known as locker ransomware, is designed to lock the computer, preventing victims from using it. In this research, we will take a look at how the ransomware types work, not just from a technological point of view but also from a psychological viewpoint. We will also look at how these threats evolved, what factors are at play to make ransomware the major problem that it is today, and where ransomware is likely to surface next.
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: History, Analysis, & Mitigation - PDF
Just as the title says, we go over the humble origins, touch on the notable variants of yesteryear, the big hitters of today, and discuss the future of ransomware. It's no longer just for windows anymore. Linux, Mac and Mobile platforms are all ripe for extortion.
This humorous and entertaining talk teaches everyone, from Mom and Pops to large enterprise organizations what's really happening and how to protect themselves.

How does your organization orient, train, and develop employees? Please share an example.
Solution
Once the organization recruits the employees they should be provided with orientation, training
and development to ensure that the employees work as per the expectations. Orientation process
involves introducing the new employees to the organization and orientation has various elements
which include describing the organization and department functions, specification of job tasks
and responsibilities, explaining the current plans to the new employees and introducing the new
employees to the coworkers. Sometimes the employees are provided with the policy handbook
which helps to understand the personal policies. In my organization we were given employee
orientation in the first day by a senior manager in the organization. He explained us the basic
details about the organization, what are the different departments in the organization and the key
functions performed by each department. The company policies also were explained to us
including the dos and don’ts in the workplace. We were given a brief introduction about what
will be our job responsibilities and the company goals. Later we were taken to our work place
and introduced to the project members.
Training is the process of teaching the skills required to perform a job to the employees and
mostly teaches the technical skills required to perform the job efficiently. Development is
intended to improve the skills of the employees which can be utilized in future as well which
include skills like communication, interpersonal and decision making skills. The training can be
given in classrooms which are known as off the job training and on the job training is given at
the work environment and the employees are trained by the manager or senior members on how
to perform the job. After orientation our training started on the next day and we were given
training and development classes in a class room setting as the part of off–the-job training. The
training helped to develop our technical as well as nontechnical skills. Once it got completed we
were sent to the work site and our senior members provided on-the-job training as well on the
steps to perform the job..
Network security
This document discusses different types of hackers and network security tips. It describes black hat hackers as those who compromise systems without permission for malicious purposes. Grey hat hackers sometimes act legally and for goodwill, and other times not. White hat hackers believe in sharing expertise to facilitate information access, though some are just exploring systems. It provides instructions for creating fake viruses to deactivate operating systems. Finally, it lists tips for securing data like strong passwords, virus protection, and educating employees on email risks.
Cyber Crime & Security.pdf
Cybercrime is a criminal activity that involves using technology, such as computers or mobile devices, to commit illegal acts. These criminal activities can range from stealing sensitive information to disrupting critical infrastructure or even extortion. Cybercrime is a growing threat, as more and more aspects of our lives become connected to the internet.
To combat cybercrime, organizations need to prioritize cybersecurity. Cybersecurity involves implementing a range of security measures, such as network segmentation, access control, encryption, threat monitoring, and incident response planning. Security must be built into the design of systems and continuously monitored and updated to keep pace with emerging threats.
Effective cybersecurity also requires employee training and awareness programs to educate staff on the risks and best practices for securing systems. By taking a proactive approach to cybersecurity, organizations can protect their assets and reputation, and prevent financial losses and legal liabilities associated with cybercrime.
___साइबर अपराध एक अपराधिक गतिविधि है जो तकनीक का उपयोग करती है, जैसे कंप्यूटर या मोबाइल डिवाइस, अवैध कृत्य करने के लिए। इन अपराधिक गतिविधियों में संवेदनशील जानकारी चुराना से लेकर आवश्यक ढांचे को अवरुद्ध करने या उत्पादन बिगाड़ने तक की विस्तृत श्रृंखला शामिल हो सकती है। साइबर अपराध एक बढ़ती हुई खतरा है, क्योंकि हमारे जीवन के अधिकांश पहलुओं को इंटरनेट से जोड़ा जाता है।
साइबर अपराध से निपटने के लिए, संगठनों को साइबर सुरक्षा को प्राथमिकता देनी चाहिए। साइबर सुरक्षा में नेटवर्क विभाजन, पहुँच नियंत्रण, एन्क्रिप्शन, खतरा मॉनिटरिंग और घटना प्रतिक्रिया योजना जैसी विभिन्न सुरक्षा उपायों को लागू करना शामिल होता है। सुरक्षा को ढांचे के डिजाइन में बिल्ट करना आवश्यक होता है और नवीनतम खतरों के साथ कदम से कदम मिलाकर मॉनिटर और अपडेट किया जाना चाहिए।
अधिकृत साइबर सुरक्षा अभ्यास और जागरूकता कार्यक्रम भी आवश्यक हैं जो कर्मचारियों को सिस्टम सुरक्षा के जोखिम और सर्वोत्तम अभ्यासों के बारे में शिक्षित करने में मदद करते हैं। साइबर सुरक्षा के लिए एक सक्रिय दृष्टिकोण अपनाकर, संगठन अपनी संपत्ति और प्रतिष्ठा की रक्षा कर सकता है और साइबर अपराध से जुड़ी वित्तीय हानि और कानूनी दायित्वों से बच सकता है।

Cryptojacking - by Vishwaraj101
Cryptojacking involves secretly using a victim's computing resources to mine cryptocurrencies without consent. Attackers can embed cryptojacking scripts on websites through vulnerabilities like cross-site scripting (XSS). When visitors access the infected sites, their browsers' CPUs are used to generate cryptocurrency for the attacker. Other cryptojacking methods include subdomain takeovers, network-level attacks by setting up rogue hotspots, and exploiting remote code execution bugs to install cryptojacking software. Website owners can prevent cryptojacking by fixing security issues, implementing content security policies and HTTPS, and monitoring CPU usage.

Hacking
The document discusses different types of hacking including definitions of hackers, crackers, and ethical hackers. It also outlines common hacking techniques like eavesdropping, spoofing, and denial of service attacks. Finally, it provides steps hackers can take to hide their identity and spread malware without leaving traces, though warns that law enforcement can still track them down.
Computer Ethics - Hacking
Hacking is a term that evokes intrigue and curiosity, often associated with unauthorized access to computer systems and malicious activities. However, it is crucial to understand that hacking encompasses a broader spectrum that includes ethical and legitimate practices as well.
Hacking, at its core, refers to the act of exploring and manipulating computer systems, networks, and software. It involves gaining knowledge, finding vulnerabilities, and discovering innovative solutions. Ethical hacking, also known as "white hat" hacking, involves using hacking skills to identify and patch security flaws, helping organizations strengthen their defenses.
On the other hand, "black hat" hacking refers to malicious activities carried out with criminal intent, such as unauthorized access, data theft, or disrupting systems. These actions are illegal and pose a significant threat to individuals, businesses, and governments.
Hacking is not confined to computers alone; it can extend to various realms, including social engineering, where psychological manipulation is employed to deceive individuals into revealing sensitive information.
To combat hacking, cybersecurity measures are essential. Organizations invest in robust security protocols, encryption, firewalls, and intrusion detection systems. Ethical hackers play a crucial role in this realm, as they employ their skills to proactively identify vulnerabilities and help protect against potential threats.
While hacking can have negative connotations, it is important to recognize that it is a tool that can be used positively to enhance cybersecurity and technological advancements. Responsible use of hacking skills, coupled with strong ethical principles, ensures that hacking is a force for good in the digital landscape
SECURITY IN COMPUTING.pptx
The WannaCry ransomware attack in May 2017 infected hundreds of thousands of computers globally using exploits from the NSA. It exploited a Windows vulnerability that many organizations failed to patch. This allowed the ransomware to spread rapidly using a worm. The attack significantly disrupted organizations in over 150 countries and caused billions in damages. A security researcher stopped the spread by registering an unregistered domain used in the malware. Users can protect themselves by updating software, avoiding suspicious links/attachments, using security software and backing up data.

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.

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
