4 Task 2- Understanding the Vulnerable Program The vulnerable program.pdf

atozshoppe

4 Task 2: Understanding the Vulnerable Program The vulnerable program used in this lab is called stack. c, which is in the code folder. This program has a buffer-overflow vulnerability, and your job is to exploit this vulnerability and gain the root privilege. The code listed below has some non-essential information removed, so it is slightly different from what you get from the lab setup file. Listing 2: The vulnerable program (stack. c) The above program has a buffer overflow vulnerability. It first reads an input from a file called badf ile, and then passes this input to another buffer in the function bof () . The original input can have a maximum length of 517 bytes, but the buffer in bof () is only BUF_SIZE bytes long, which is less than 517. Because strcpy () does not check boundaries, buffer overflow will occur. Since this program is a root- owned Set-UID program, if a normal user can exploit this buffer overflow vulnerability, the user might be able to get a root shell. It should be noted that the program gets its input from a file called badfile. This file is under users' control. Now, our objective is to create the contents for badfile, such that when the vulnerable program copies the contents into its buffer, a root shell can be spawned. Compilation. To compile the above vulnerable program, do not forget to turn off the StackGuard and the non-executable stack protections using the -fno-stack-protector and "-z execstack " options. After the compilation, we need to make the program a root-owned Set-UID program. We can achieve this by first change the ownership of the program to root (Line (1), and then change the permission to 4755 to enable the Set-UID bit (Line (2)). It should be noted that changing ownership must be done before turning on the Set-UID bit, because ownership change will cause the Set-UID bit to be turned off. The compilation and setup commands are already included in Makefile, so we just need to type make to execute those commands. The variables L1, ..., L4 are set in Makefile; they will be used during the compilation. We have chosen a different set of values for these variables, you need to change them in Makefile. The values are listed below: - L1: 100 - L2: 150 - L3: 200 - L4: 10 5 Task 3: Launching Attack on 32-bit Program (Level 1) 5.1 Investigation To exploit the buffer-overflow vulnerability in the target program, the most important thing to know is the distance between the buffer's starting position and the place where the return-address is stored. We will use a debugging method to find it out. Since we have the source code of the target program, we can compile it with the debugging flag turned on. That will make it more convenient to debug. We will add the g flag to gcc command, so debugging information is added to the binary. If you run make, the debugging version is already created. We will use gdb to debug stack-L1-dbg. We need to create a file called badfile before running the program. Note 1. When gdb .

3-4 Regulation of miRNA availability miRNA genes are transcriptionally.pdf

atozshoppe

3.4 Regulation of miRNA availability miRNA genes are transcriptionally regulated just like any other gene, so their levels in the cell can be controlled through these routes. However, there is one additional way in which the availability of miRNAs within a cell can be regulated. This is through the hybridisation to competitive endogenous RNAs. These RNA chains appear to act as 'sponges', competing with target mRNAs within a cell for binding, and therefore acting as regulators for the effects of a miRNA (Figure 3.6). Figure 3.6 Endogenous RNAs, including circular RNAs, can serve as regulators of miRNAs through competitive binding. Competitive regulation of miRNAs in the cellular pool serves to regulate both the translation blocking effects of 3 UTR binding and the targeting of mRNAs for degradation. Schematic diagram to show how endogenous RNAs can regulate miRNAs through competitive binding. The blue background indicates the cytosol, mRNA are orange strands and the miRNAs are magenta. At the centre is a pool of 6 miRNAs shown, which can target mRNA for degradation (bottom) or bind the 3'UTR of mRNA to block translation of the mRNA (top right). However, this miRNA regulatory role is itself subject to regulation through competitive binding with endogenous RNAs such as the circular RNA pictured (top left). The miRNAs bound to circular RNA are not available to regulate the mRNA until they are released. One of the first well-characterised examples of this was provided by Hansen et al. (2013). These researchers identified a circular RNA chain called ciRS-7 in the mouse brain (see Figure 3.7a, left). The ciRS-7 RNA contains over 70 sites with sequence complementarity to miR 7 (Figure 3.7b). (b) View larger image Figure 3.7 The circular RNA ciRS-7 acts as a sponge, regulating the availability of miRNA miR-7. (a) Both are expressed in the same cells in the brain, as shown by similar patterns of brown staining in mouse brain sections. (b) ciRS-7 carries multiple target sites for miR-7, drawn here to represent the base conservation along ciRS-7 for each site complementary to miR 7 . for miR-7) acting as a sponge to regulate the availability of miRNA miR-7. a. Mouse brain sections stained with a probe to detect ciRS-7 (left) and miR-7 (right). Note the similar distribution of brown staining in both images indicating similar distribution patterns of both miRNA and ciRS-7 in the mouse brain sections (eg the ' C '-shaped brown staining in the hippocampus region; you can ignore the staining intensity differences between the two images in the cortex). b. The orange bar represents the gene for ciRS- 7 gene. Above it is a graph showing degree of similarity to the miR-7 RNA sequence. The taller the hight of the black block, the closer the match. Note that there are over 70 such conserved sites showing sequence complementarity to miR 7 .

2024.06.01 Introducing a competency framework for languag learning materials ...

Sandy Millin

http://sandymillin.wordpress.com/iateflwebinar2024 Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error. Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials. This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

The Roman Empire A Historical Colossus.pdf

kaushalkr1407

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.

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

A Strategic Approach: GenAI in Education

Peter 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.
