Background and Introduction
The recent trend in mobile computing has led to a plethora of relatively inexpensive high power computing devices that can fit in a shirt pocket. These new devices are capable of internet connectivity and are location aware, making this new technology both highly useful and just as dangerous in the hands of malicious hackers. In November of 2009, the first iPhone virus was released. It was not malicious and only changed the user’s background picture. [1] This first worm was written as a proof of concept to warn of the potential dangers of viruses for mobile devices. The author stated in a later interview with ABC his reasons for creating the virus: "I think to raise awareness for one, somebody with more malicious intent could have done anything - read your SMSs, go through your emails, and view your contacts, photos – anything."[2] Less than a month later, another virus was released by someone with malicious intent, capable of stealing private information, behaving as part of a “bot-net”, and even allowing the attacker to install other malicious software on the device. [3] With the prevalence of iPhone-like devices it is becoming more important to be able to quickly analyze and reverse engineer malicious code to protect users.
Since the iPhone’s release, over 1 billion applications have been released resulting in a 40 billion dollar market [4]. The importance of keeping track of the source code of a company’s intellectual property is paramount. Software piracy is always a consideration in the computer engineering field. To counteract this threat, several methods have been developed to render pirated applications inert, preventing them from performing their intended function. These same methods imp...

...ctive C only one function is called; objc_msgSend()is responsible for all method calls. The goals of this project are to create a method for recreating as much source information as possible with little or no user intervention from a source executable.
To reverse engineer a program from object code with no debugging information to original source code is considered by many to be impossible and at the very best a NP-Hard problem. [5] However, by concentrating on a static analysis of the Objective C binary a great deal of information can be constructed that will lead to a close approximation of the original source code. The attempts at decompiling are made easier by the fact that all applications written for the iPhone are compiled with Apple Inc.’s compiler, a variation of the GNU compiler. Therefore, we need only write one back-end to recognize the assembly idioms.
In this micro-study, I will use tools and information available to the public via internet in attempt to hack the iPhone. Currently the iPhone is only sold to subscribers of the AT&T telecommunication service provider and all applications and updates are installed using Apple’s iTunes software. Using various resources I will focus the two main issues which have put Apple and the iPhone user community into the limelight. First, the “unlocking” of the iPhone, which bypasses the iTunes activations process and allows the device to be used on any SIM (Subscriber Information Module) card cellular phone service provider other than AT&T, in this micro-study I will be using a T-Mobile SIM card. Second, I will attempt to “jailbreak” the device, which will allow me to install third-party applications through underground sources and not directly from Apple. As I attempt to hack the iPhone, I will compare drawbacks and benefits of hacking methods, ease of use, and verify Apple’s claims on affecting functionality and possible damag...
Though it is often overlooked today in favor of its counterpart digital music protection, software content protection is an extremely serious issue, and many contend that it has the potential to stunt the growth of technology if it is mishandled. The debate concerns software piracy (often simply using a program you didn’t actually pay for), and the proper legal protection that should apply to such software programs. Due to space constraints, I intend to confine our discussion here to an overview of the software patent and copyright issues in the United States and the UK – two of the world’s most advanced countries with widespread software development and use, and therefore great potential for misuse. And as no treatment of this issue can be complete without a look at its ethical ramifications, I will finally propose a solution to the software protection problem, and justify it with ethical as well as pragmatic motivations.
The evolution of cyber threats has reached a critical point where hackers withhold important information in exchange for payment. In the last three decades, the Internet has fundamentally changed the way people, governments, and private organizations store, use, and manage information. The age of the Internet of Things has left everyone at the risk of a ransomware attack (Richardson and North 13). The ubiquitous connection to the Internet through mobile devices such as tablets, smartphones, and laptops has made the Internet the obvious and convenient place to store personal data including photos, research information, and business records. The challenge is that cybercriminals have developed a new way of getting illegitimate
The popularity and use of smart phone in daily life is increasing exponentially. So today we depend much on our phone and even store very important data on our phone. So it becomes very important to cope up with challenge posed due to malicious software or notoriously known as malware. But to prevent our phone and develop malware detecting software it is very important to understand the behavior of these malware .Keeping that in mind this paper aims to have a understanding of –what is malware and its distribution in android smart phone as android phone covers a large proportion of smart phone built today. This paper also discusses a study carried by Berkley University for malware infection rate and a popular app “Carat” used for study. Then we list the algorithm used and our implementation of algorithm. We also propose an app developed for the specific purpose.
News of source code theft jolted the software industry on February 12, 2004.2 Cyber criminals had stolen source code from Windows 2000 and Windows NT4.0. Windows 2000 and NT are the platforms on which the widely used home operating system of today, Windows XP, is based on. Luckily, only a small portion of code was stolen. Not nearly enough to build the entire Windows operating system. Through the use of peer-to-peer networking, the code was distributed in an underground hacker network. Eventually the source was spread onto public-access web sites, by which Microsoft confirmed the code was, indeed, real Windows code.
Software piracy is a complicated issue with no simple solutions or simple causes. First we’ll try to explain the reason why people might commit software piracy, and then we’ll attempt to explore how they might rationalize there actions.
In the computer age, vulnerabilities and back doors into devices are proving heaven for hackers and hell for administrators. Every week it seems that new vulnerabilities are discovered in different devices. Cisco IOS is no different and numerous vulnerabilities can be found in their devices. The aim of the report is to research vulnerabilities in Cisco's IOS operating system. Tools available in Backtrack 5 will be used to exploit the vulnerabilities. GNS3 will be used to set up a working topology to work in conjunction with Backtrack 5 to demonstrate the tools. The report also contains screenshots of the tools that will aid the readers understanding.
Compilers collect and reorganize (compile) all the instructions in a given set of source code to produce object code. Object code is often the same as or similar to a computer's machine code. If the object code is the same as the machine language, the computer can run the program immediately after the compiler produces its translation. If the object code is not in machine language, other programs—such as assemblers, binders, linkers, and loaders—finish the translation.
In the 1980s no one who was anyone, went anywhere, without his or her Filofax. The end of the 1990s had replaced it by its digital equivalent - the Personal Digital Assistant (PDA). A PDA is effectively a handheld PC, capable of handling all the normal tasks of its leather-bound ancestor - address book, notepad, appointments diary and phone list. Most PDAs offer many more applications besides, such as spreadsheet, word processor, database, financial management software, clock, calculator and games. PC users have the ability to transfer data between the handheld device and a desktop PC and to convert data to and from existing organizer applications. They also achieve connectivity either via an infrared port or a special docking station.
Smartphone’s, PADs, tablet computers and other handheld devices that are used to run over operating system are called mobile operating system (Mobile OS). A specified data and programs that run over the mobile devices are referred as mobile operating system. It handles all the hardware and optimizes the performance of the application software in the device. Mobile multimedia functions, Internet connectivity and many other applications are handled by mobile operating system. Base infrastructure software inherent of a computerized system is operating system. It controls all primitive operations of the computer such as PDA and Smartphone. To install and execute the third party applications (known as apps) by users are allowed in the operating system devices. It enumerates new functionalities of the devices. Today mobile devices with a desired OS are called Smartphone’s and a wide range of applications for instances games, apps,communication or social media apps, digital maps, etc are used by users.
Virus is one of the most common malware. Unlike spyware, virus is largely designed to harm useful programs or wreck down an entire operating system. There are many ways through which virus may enter a computer. The most common way is via email attachments. A...
Have you ever asked yourself, what the world would be like if there weren’t any mobile applications. Society is impacted by the new development in technology daily. Someone is always claiming that their inventions will revolutionize the world, but no invention has had more success over the years, in the cellular world than mobile applications. People all around the world use millions to billions of applications daily for personal and business uses. For example, social networking which is use by all generations of people. It has an influence the way we purchase cell phones, in order to have the capability. With the creation of different smartphones and tablets, comes the demand for more mobile applications. This causes competition among application builders. Mobile applications are designed to its user making their experience less complicated. Mobile applications have their advantages and disadvantages, depending on its design and designer. They can be created to be very simple or complex, depending on its intended function. Has society benefited from the usages of mobile applications or is it just a distraction. What impact do mobile applications have on society.
In today’s days malware is designated as a software which aims to disturb a computer with the consent or permission of the owner. This term “Malware” is used by computer professionals to describe a varied forms of destructive, annoying and intrusive software code. This word “Malware” is used to indicate all types of malware which include a true set of viruses.
...h the threat of “Mobile Malware” looming in the air, the desire to give the general public fair warning has never been greater. This paper was intended to provided that knowledge the general public needs and will reinforce the topic to those who were already aware. The history of malware gave you a look into the not so distant past. The discussion of technical examples of malware was intended to show you how rapidly the threat is developing along with the statistics of malware’s current expansion, and the future examples of malware and research showed you concepts that were unimaginable to the common electronic consumer. The majority of malware was originally designed to be a practical joke, but as we can see from the ever growing desire for malicious intent, the evolution of malware has followed suite. We can only hope that the growing need for security can be met.
As the decade passed by, a bunch of inventions are produced and the innovation was successfully exceeded. Some products today are thin-laptops, tablets, touch phones etc. But despite of these innovations, there is a program that can harm those gadgets and it can lead to software destruction. It is what we called “virus”, Viruses are well known computer attackers, and they cause a big damage to your computer. There are several types of viruses and each have the power to compromise your computer in different ways. Usually, users can get a virus by downloading questionable files without knowing that it contain viruses.
