Removing Uninteresting Bytes in Software FuzzingAftab Hussain
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.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Weather - the state of the atmosphere - considered on a daily basis - different from climate - climate is how a region is normally, seasonal, over a longer period of time - determinants: - temperature - pressure - wind - humidity - precipitation http://www.windows.ucar.edu/tour/link=/earth/Atmosphere/weather.html
Basic Temperature – the measure of the average speed of air molecules - described as hot or cold - measured in degrees using a thermometer - temperature of the air depends on temperature of the surface below it - why temperature decreases as altitude increases Global warming - Greenhouse effect : sunlight (shortwave radiation) reaches Earth some is reflected, some is absorbed and heats the Earth absorbed sunlight re-emitted as infrared (longwave radiation) greenhouse gases reflect some infrared which reheats the Earth and then is re-emitted - human and other activities increase greenhouse gas concentration more gases absorb and re-emit infrared adds more heat to the surface of the Earth increase in temperature global warming - 1990 was the hottest year in the last century, 1991 was the second - 1983, 1987, 1988, 1989, 1990, 1991 have been the hottest 6 years in the last century - the planet’s temperature has increased 0.5 degrees Celsius since 1900 - Northern Hemisphere will heat up more than the Southern Hemisphere because water absorbs more heat than land and there is more ocean in the south - predicted increase from 3 – 5 degrees Celsius by 2100 http://www.windows.ucar.edu/tour/link=/earth/Atmosphere/weather.html http://www.geocities.com/TimesSquare/1848/global.html http://timeforchange.org/cause-and-effect-for-global-warming
Basic Pressure – an idea that scientists use to describe how gases and liquids “push” on things - this “push” comes from the movement of molecules and atoms - air pressure decreases as altitude increases - air moves from areas of high pressure to areas of low pressure wind - air moves away from high pressure , creating a hole air from above moves in sinking air evaporates from a condensed form (clouds) into water vapor - air moves into low pressure air moves upwards rising air condenses water vapor into a condensed form (clouds) - many different measures of pressure - pascal, kilopascal - bar, milibar - pounds per square inch - measured using a mercury barometer, an aneroid barometer, or a barograph - when talking about high and low atmospheric pressure, the measurement is all relative Global Warming - increased land temperatures increased air temperatures air becomes less dense hot air rises low air pressure “thermal low” creation of clouds , water condensation into water droplets or ice crystals increased precipitation - the areas around the equator , the “tropics” intertropical convergence zone receives more heat large amounts of warm, rising air low pressure humidity in rising air condenses contributes to large thunderstorms http://www.windows.ucar.edu/tour/link=/earth/Atmosphere/weather.html http://www.usatoday.com/weather/tg/whighlow/whighlow.htm http://www.usatoday.com/weather/resources/askjack/2003-03-18-archive-air-pressure_x.htm Basic Wind – moving air - warm air rises, cool air sinks - Coriolis Effect: winds move to the right in the Northern Hemisphere, winds move to the left in the Southern Hemisphere - prevailing winds: a type of wind that usually blows into a region - ex. Trade Winds flow steadily towards the equator - ex. Jet Streams are narrow zones of strong winds in the upper troposphere - Beaufort Scale: shows different speeds and names of winds - calm air breezes strong winds, gales - directional winds - Easterly, east west - Westerly, west east Global Warming - land heats faster than water air above land warms and rises quicker than air above water cool winds from above water move over land “sea breezes” - intertropical convergence zone a lot of cool air moves in to replace the large amount of warm rising air tropical Trade Winds - the air that rises moves towards the poles some settles in the mid-latitudes to create high air pressure - some continues to the polar regions turned by Earth’s rotation easterly and westerly winds http://www.windows.ucar.edu/tour/link=/earth/Atmosphere/weather.html http://www.usatoday.com/weather/resources/askjack/2003-03-18-archive-air-pressure_x.htm Basic Humidity – the presence of water vapor in the air - water and ice condense into water vapor Global warming - increased ocean temperatures more water condensed from oceans and land more water vapor more humidity http://www.w-dhave.inet.co.th/humidity.html http://afp.google.com/article/ALeqM5i76P2MdxqZpEOyfiHRbdcJ38_K-g
Basic Precipitation – any form of water that falls to the Earth - drizzle, rain, hail, snow, sleet, etc. - opposite is evaporation – when water goes from the liquid phase to the gas phase Global warming - more intense hydrological cycle - overall increase in rain and snowfall - generally more precipitation in winter - evaporated moisture moving towards the poles (in mid-high latitudes) - more evaporation in summer - predicted patterns - increased precipitation in polar and subpolar regions - decreased precipitation in mid-latitudes of both hemispheres - increased precipitation around the equator - decreased precipitation in the subtropics - increases in rainfall will come in the form of more intense storms rather than more rainy days - increased air temperature evaporation increased water vapor in the air not necessarily more frequent rainfall, but more moisture for storms - warmer atmosphere hold more water vapor more heavy precipitation extreme events http://www.windows.ucar.edu/tour/link=/earth/Atmosphere/weather.html http://www.ucsusa.org/global_warming/science_and_impacts/impacts/early-warning-signs-of-global-3.html http://earthobservatory.nasa.gov/Features/GlobalWarming/global_warming_update6.php http://www.britannica.com/EBchecked/topic/235402/global-warming/274848/Precipitation-patterns http://www.geocities.com/csango80/gwweb04.htm
Floods - greater evaporation + more precipitation intense precipitation flooding Droughts - warmer surface temperatures + less precipitation greater evaporation less soil moisture droughts Heat waves - increased land temperatures Extreme winter cold and snow fall - evaporated moisture moving towards the poles increased precipitation in winter snowfall Tornados - wind movement? Extreme storms tropical cyclones/hurricanes/typhoons - warmer ocean and air increased rate of evaporation and condensation to make a storm increased rate and strength of hurricanes - increased humidity worse tropical cyclones http://www.tropical-rainforest-animals.com/Global-Warming-Effects.html http://www.britannica.com/EBchecked/topic/235402/global-warming/274848/Precipitation-patterns http://www.geocities.com/csango80/gwweb04.htm http://afp.google.com/article/ALeqM5i76P2MdxqZpEOyfiHRbdcJ38_K-g Hurricanes – a tropical storm that has sustained wind speeds of over 74 mph - categorized in severity from 1 – 5 - power from the heat of the ocean - warmer oceans more intense and more frequent hurricanes - more numerous and intense since 1995 Wildfires - increased temperatures less rainfall drier trees and plants better fuel for fires - warmer winter temperatures more tree killing beetles and insects survive more dead, flammable trees - snowmelt occurs earlier in the year dries trees and plants in the spring and summer - wildfires give off the equivalent of 40% of the carbon emissions from burning fossil fuels more global warming more wildfires - annual number of wildfires is 6x greater after 1986 than the average before 1986 - “wildfire season” (summer) has lengthened - past few years, wildfires have burned millions of acres Droughts - increased temperatures greater rate of evaporation - in areas where bodies of water are temporary, their availability is decreasing - in areas of dry soil, little water is lost to evaporation no rain clouds formed less rain even dryer soil - expected to effect the interior parts of large continents , like agricultural areas crop failure, starvation Heat waves - increased temperatures increased maximum temperatures - summer 2003 was the warmest ever 27,000 died - chances for a fatal heat wave have doubled - changes for a fatal heat wave will increase 100 fold in the next 30 years Flooding - increased temperatures increased rate of evaporation increased formation of rain clouds with more water vapor increased rainfall - El Niño: periods of high temperatures in the eastern Pacific ocean - increased rainfall closer to the equator, like southern US and Peru - decreased rainfall in places like northern US, parts of Brazil, Asia, Africa, most of Australia - increased temperatures longer and more intense El Nino seasons more intense droughts and floods in affected areas http://www.effectsofglobalwarming.com/Extreme-weather-caused-by-global-warming-and-the-effects-on-our-environment.html
Uncertainties - how much humans are contributing to the accumulation of greenhouse gases the amount of global warming - Intergovernmental Panel on Climate Change (IPCC) said warming trend is “unlikely to be entirely natural in origin” - “There is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities.” - how much increases in greenhouse gases are contributing to global warming - other factors contribute to increasing temperatures: - natural climate variations - changes in sun’s energy - cooling effects of pollutant aerosols - how much and how fast global temperatures will rise - IPPC project further global warming from 1.4 to 5.8 degreed Celsius by 2100 - the low end of this projection “would probably be greater than any seen in the last 10,000 years” - other factors: - uncertainties in greenhouse gas emissions - possible cooling effects of atmospheric particles like sulfate - climate’s response to changes in atmosphere - more accurate predictions for changes on a large scale vs. a small scale - large scale: global temperatures, precipitation changes, average sea level rise - small scale: local temperature and precipitation changes, altered weather patterns, soil moisture changes - IPCC said “complex systems, such as the climate system, can respond in non-linear ways and produce surprises.” - ex. hurricanes and other intense storms evidence that they will be stronger unsure if they will be more frequent - ex. how global warming will effect El Nino http://www.teachervision.fen.com/global-warming/resource/44462.html
