What is a Mobile Threat?
Like viruses and spyware that can infect your PC, there are a variety of security threats that can affect mobile devices.
Pegasus scandal
Pegasus is spyware created by the Israeli company NSO Group to track targets by accessing their device's data, apps, camera, and microphone. It can be sent remotely to infect phones. While NSO claims it is only for authorized governments to use against criminals and terrorists, the recent Pegasus Project revealed its use against journalists, activists, and politicians in multiple countries. The spyware raises concerns over privacy violations if used improperly by governments or other groups.

What is wanna cry ransomware attack
Here we have collected some important information about Wanna Cry Ransomware attack. After reading this you will be able to identify this virus.
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.
14 tips to increase cybersecurity awareness
We used this presentation within our company to increase the cybersecurity awareness of our employees. These 14 tips should help everybody to protect themselves against the most obvious cyber attacks.
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.
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.
RSA Monthly Online Fraud Report -- August 2013
This report offers insight on the latest trends in phishing, malware and cybercrime around the world.
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.
Cybersecurity Awareness
This is a basic presentation about cybersecurity to share awareness about various security threats and how you can protect yourself from them. In the preview window the formatting is off, but when downloaded it can be viewed with no problems. This is for my Info Security Policy Management class at Governors State University.
Ethical Hacking and Network Security
Hi, friends today Iam presented my ppt on ethical hacking and network security. This will gives you some basic tips and ideas about hacking and how to make our network secure.
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."
The need for security
The document discusses information security threats and malicious attacks. It describes how attackers have motives like disrupting operations or stealing information, and use methods that exploit vulnerabilities. Some major threats are employees, natural disasters, and outside attackers seeking to deny service, steal information, or damage systems. Malicious attacks specifically aim to abuse computers through viruses, social engineering, or reducing functionality. Examples of malicious attacks discussed are logic bombs that disabled company systems, compromised bank accounts through contractor access, and an system administrator refusing to share passwords for a city network.
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.
Social and Mobile and Cloud OH MY!
This document discusses emerging security challenges in an increasingly mobile, social, and cloud-based computing landscape. It notes that traditional perimeter-based security is ineffective as computing becomes more ubiquitous and decentralized. Mobile applications and social networks provide fertile ground for malware propagation. Cloud services mean data can take complex, indirect paths outside of a user's control. Passwords are often trivial to guess. Code from third parties and libraries may introduce vulnerabilities. A new security paradigm is needed to address these challenges, as permissions alone will not suffice. Users must think differently about security in this new environment.
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.
Powerpoint fp
The document contains information about two students, Kevin Power and Daniel O'Malley, enrolled in an MSc Information Systems Management program. It discusses various cybersecurity topics such as the difficulty of staying ahead of hackers, vulnerabilities in web browser design, the importance of using unique passwords on different sites, and different types of cyberattacks like zero-day exploits, injection attacks, and phishing. Popular web browsers and bug bounty programs rewarding hackers for discovering vulnerabilities are also mentioned.
Ransomware (1).pdf
The document discusses the history and evolution of ransomware attacks from 1989 to the present. It provides details on notable ransomware attacks like WannaCry in 2017 and NotPetya in 2017. WannaCry spread to over 150 countries and encrypted data on hundreds of thousands of computers, demanding ransom payments in bitcoin. It exploited a Windows vulnerability. NotPetya similarly spread rapidly through Ukraine and globally, affecting a major shipping company and causing over $10 billion in damages by encrypting and wiping data. The document outlines the modus operandi and impacts of these attacks as well as measures to prevent future ransomware infections like patching systems, isolating infected devices, and implementing security best practices.
Your money or your files
One of the key methods cybercriminals are using is ransomware, most famously the Cryptolocker malware,
and its numerous variants, which encrypts the files on a user’s computer and demands the user to pay a ransom, usually in Bitcoins, in order to receive the key to decrypt the files. But Cryptolocker is just one approach that criminals are taking to demand ransom, and the techniques are evolving on a daily basis. To guard against ransomware, it is not enough to know the malware that is making the rounds that day. It is vital to have a broader understanding of the topic, so one can take effective countermeasures against this evolving threat.

Bad Rabbit type of ransomeware
On 24 October 2017, some users in Russia, Ukraine ,turkey and some eastern uropien countries reported a new ransomware attack, named "Bad Rabbit", which follows a similar pattern to WannaCry and Petya by encrypting the user's file tables and then demands a Bitcoin payment to decrypt the lock. Bad Rabbit is a ransomware virus that affects Microsoft Windows based systems. While bad rabbit is doesn’t appear to include the eternal blue windows exploit that was stolen from the NSA and not Petya and WannaCry, it does use one of the agency’s security flaws. It also uses internal Romance exploit to spread within the network
Ransomware Review 2017

Sit presentation - Hacking
Hacking involves illegally accessing computer systems or networks. There are different types of hackers, including white hats who test security, black hats who hack with malicious intent, and grey hats who sometimes help for a fee. Common hacking techniques are password cracking, viruses, Trojan horses, and keyloggers. The Computer Fraud and Abuse Act of 1984 made hacking illegal but some argue it is too broad. Famous hackers include Adrian Lamo and Jonathan James who were black hats, and Wozniak and Berners-Lee who were white hats. The Stuxnet virus targeted Iran's nuclear facilities. Anonymous is a hacking group known for hacktivism. Major hacking events include the "I Love You" virus of 2000

Evolution of ransomware
The evolution of ransomware began in 1989 with the AIDS Trojan virus, moving to more advanced encryption techniques over time. By 2013, CryptoLocker used strong encryption via RSA 2048-bit keys and Bitcoin payments, making ransomware payments hard to trace. Later strains like CryptoWall and Locky continued advancing techniques to infect more systems and ensure payment, demonstrating ransomware as an ongoing cybersecurity threat.
Cyber crimes (By Mohammad Ahmed)
Your computer contains evidence of any cyber crimes committed using that device. As the crime scene, investigators can examine the computer's files, browser history, and other digital traces to uncover the perpetrator's identity and activities. Maintaining good cyber security practices and being aware of how digital data can be used against you are important ways to protect yourself and others online.
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.

The criminal hacking group Fin7, which was behind the Colonial Pipeline ransomware attack, has set up a fake cybersecurity company called Bastion Secure to recruit new technical talent. Bastion Secure's job postings and website appear legitimate, but researchers traced it back to Fin7. One potential recruit grew suspicious when asked to install hacking tools and collect network information without explanation. By impersonating real companies, ransomware groups are able to expand their operations and access more skilled workers, showing how these criminal networks are becoming increasingly professionalized.PP Lec15n16 Sp2020.pptx
Hacking and identity theft are growing problems as more information is stored and transmitted digitally. Hacking ranges from minor pranks to serious crimes like theft of personal information or disabling of critical systems. Early hackers were motivated by intellectual challenge, but now criminal gangs conduct hacking for financial gain. Identity theft involves stealing personal information like social security numbers to commit fraud. Criminals use phishing emails and websites to trick victims into revealing private details. Biometrics like fingerprints offer more secure identification than cards or passwords that can be stolen. Laws aim to prevent digital crimes while protecting free speech rights of "hacktivists".

Rainfall intensity duration frequency curve statistical analysis and modeling...
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.

Comparative analysis between traditional aquaponics and reconstructed aquapon...
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Medical image analysis has witnessed significant advancements with deep learning techniques. In the domain of brain tumor segmentation, the ability to
precisely delineate tumor boundaries from magnetic resonance imaging (MRI)
scans holds profound implications for diagnosis. This study presents an ensemble convolutional neural network (CNN) with transfer learning, integrating
the state-of-the-art Deeplabv3+ architecture with the ResNet18 backbone. The
model is rigorously trained and evaluated, exhibiting remarkable performance
metrics, including an impressive global accuracy of 99.286%, a high-class accuracy of 82.191%, a mean intersection over union (IoU) of 79.900%, a weighted
IoU of 98.620%, and a Boundary F1 (BF) score of 83.303%. Notably, a detailed comparative analysis with existing methods showcases the superiority of
our proposed model. These findings underscore the model’s competence in precise brain tumor localization, underscoring its potential to revolutionize medical
image analysis and enhance healthcare outcomes. This research paves the way
for future exploration and optimization of advanced CNN models in medical
imaging, emphasizing addressing false positives and resource efficiency.

Wanna-cry Ransome ware
- 1. CYBER SECURITY AWARENESS RANSOM WARE ABHAY PATHAK Presented By:- Abhay Kumar Pathak (Ethical Hacking VAPT Certified) Dept:- Cs & IT
- 2. Ransom ware The Biggest Attack on Internet History As it is called a malicious program - that locks the device your computer, tablet, Smartphone and demands a ransom(Money) to unlock it. It hits the device when navigating through the various hacked websites, downloading a file or on clicking wrong link. Every 40 seconds, a company gets hit by a ransom ware. Unfortunately, it’s more sophisticated and disruptive to your operations. 2017 is being swept by the ransom ware, and this does not seem to end. ABHAY PATHAK
- 3. 2017’s biggest ransom ware cyber attack Petya-The second massive cyber attack, a variant of the ransom ware petya re-arranged using the same eternal blue exploit and hits organisations world wide, especially Ukraine, is found to exploit MS office and SMBv1 vulnerabilities and has worm capabilities, allows it to spread, quickly across infected networks. ABHAY PATHAK
- 4. Wanna-Cry Ransom Ware The first Ransom Ware was called AIDS trojan which emerged in 1989, it was spread through Floppy Disk, and the victims were asked to send an amount of $189 to a postal address of PANAMA as Ransom. May 12, 2017 witnessed the biggest ever cyber attack in the internet history. A Ransom ware named Wanna-cry stormed through the network. It targeted computers running windows OS that are not up-to-date and brought computer systems from Russia to china and the US to their knees. ABHAY PATHAK
- 5. Who was responsible? The Vulnerability ,which was discovered was called ETERNAL BLUE , which was released by a unknown hacking group calling themselves Shadow Groups who was responsible for the Cyber Attack ,and the code was written by EQATION GROUP (according to NSA). ABHAY PATHAK
- 6. Carbon Black Report on Wanna-Cry Carbon Black estimates that about 6,300 vendors of ransom ware exist on the dark web, with more than 45,000 listings. These are websites where anyone can buy anything from software for $1 that can lock up a Smartphone to customized ransom ware packages complete with source code for $1,000 or more, according to the report.
