Malicious Threats, Vulnerabilities and Defenses in WhatsApp and Mobile Instan...Jaime Sánchez
Global surveillance emerged as a phenomenon since the late 1940s and Internet and mobile technology are being developed with such pace that it is impossible to guarantee electronic privacy and nobody should expect it. How strong are the actual Instant Messaging Platforms? Do they take care of our security and privacy? We'll look inside the security of several clients (like BBM, Snapchat, and Line) and will put our focus on WhatsApp.
WhatsApp might not be as widely known as Twitter, but the company announced that it has passed 350 million active monthly users. WhatsApp has been plagued by several security issues in the past, so we decided to start the research. We've discovered several vulnerabilities more that we'll disclosure (with proof of concept code), including encryption flaws, remote DOS (making the client crash by sending a custom message), or how to spoof messages manipulating sender address information.
We'll also release a new version of our tool with different protection layers: encryption, anonymity, and using a custom XMPP server. It's necessary to implement additional measures until WhatsApp decides to take security seriously.

Dangers of the Internet Essay
Dangers of the Internet
There are many pitfalls and perils on the Internet. Some of them are easy to avoid while other are not so obvious. Some of the Pitfalls and perils are annoying, while others are deadly to your computer. Still others are humorous and entertaining. There are many dangers on the Internet. This paper will try to cover some of them.
The biggest dangers of the Internet are virus. Viruses are small programs that infect computers. Most viruses are made to steal and or destroy data stored on the infected computer. Viruses, that destroy data, write their code into a file and when that file is accessed it rewrites itself in to more files until the virus corrupters or infects a file that the computer needs to run...show more content...E mailed Viruses are harder to avoid. Opening an attached file can trigger them or by touching the message that contains the attached file and then the file menu bar of the E mail program. (Email Hole Exposes Computers) The seconded way to start a virus is because of a hole in Netscape s mail program and also MS s Outlook. A new way for Viruses to be spread by E mail is to put the whole code for the virus in the subject line that way when the computer read the subject line it unwittingly activated the virus. The newest way for people to get viruses is through the web pages. This is done by putting the virus code into a script on the web page, now when the page is accessed the viruses executes the viruses code. (Virus Thrives on HTML) This can make a virus very prolific if a lot of people visit the web page.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

2. What is a virus?
Viruses are, by definition, small infections that
replicate inside the cells of a living organism.
Like their predecessors, a computer virus is a
program which can replicate itself and then
spread from one computer to another.
Sometimes, malware, adware and spyware are
called viruses, although they cannot replicate
themselves. Instead, they can exploit the
security of the computer as well as computers
within their network.
Some viruses can harm a computer’s data or
performance, but many are harmless.
3. Why are viruses
created?
We all dread the knowledge that our
computer may be infected with a
virus. But why would anyone go
to the trouble and expense of
creating one? There are many
reasons why a computer virus
may be created. Here are some of
them…
4. 1. To Control the
computer
This enables the creator of the virus to
attack web servers by having each
infected computer sent information to the
server, thus overloading the system, and
shutting down the server (which may
host a rival website). It can also be used
to send spam to infected computers.
5. 2. To generate money
The virus may pretend to offer free
spyware or virus removal tools. Once
installed, they will “scan” your computer
and find all sorts of viruses that they will
remove, provided you pay for the full
version of the application.
6. 3. To steal your
information
They may actually be able to keep
track of everything you type on the
keyboard, thus providing access to
your passwords, account numbers
and personal information.
7. 4. Just because they
can
Yes, some people would stoop this low
to deliver a message, such as a virus
which would cause your computer to
restart with the message: “billy gates
why do you make this possible? Stop
making money and fix your software!”
(actual virus!)
8. 5. To shut down a
computer or network
Although viruses that shut down a
computer are not as common as they
once were, viruses to shut down a
network are very common. Known as a
DNS (denial of service), they will cause a
excess amount of activity on a network,
shutting it down eventually.
9. Email and viruses
One of the most prevalent ways to
spread a virus is by using Email.
Although most of us use Email on a
daily basis, many of us are naïve of
the consequences of a “bad” Email.
Let’s look at some of the ways that
viruses are spread by Email.
10. 1. A Virus as an Email
Hoax
Although not the worse thing that can
happen, an email may contain false
information (a child needing an organ
transplant or a virus warning). This will
not infect your computer, but can clog up
the email servers of the recipients,
making it a waste of time, resources and
energy. To read more about email
hoaxes, see Hoax-Slayer.
11. 2. In an Email
attachment
This is a clear reason why you don’t open
attachments if you are not sure who sent them, or if
they are authentic. These attachments can contain
viruses which run programs, or infect programs on
your computer (such as Word or Excel). The harm
only occurs if you open the attachment, so if you are
unsure, delete the email. Caution: If your contacts
have been affected by a virus, they may be sending
you a rogue infection without you knowing. In this
case, to be safe, save the attachment to your hard
drive, and then scan it with your virus scanner.
12. 3. In the body of the
Email
It is now possible to place a virus right into the
e-mail. In this case, the virus will be
automatically triggered when you open the
email. This is done by embedding the message
into the email. You will usually see a warning
asking you to click if you want to see embedded
information. Only do this if you are certain of
the source. Also, be wary of URLS (links to a
web page) which may actually link you to a site
where a virus will be downloaded. If you are not
certain of the sender, don’t open URLS in your
email.
13. Summary
• Verify the source of any suspicious email
before you open it
• Do not blindly forward e-mail
• Do not open attachments or links unless you
are certain of the sender
• Use caution when authorizing your computer
to display content of trustworthy sources
• Make sure that your email program does not
automatically download and open
attachments or display HTML content
(embedded)
