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.

Cases can come in many different sizes (known as form
factors). The size and shape of a computer case is usually
determined by the form factor of the motherboard, since it is
the largest component of most computers.
Consequently, personal computer form factors typically specify
only the internal dimensions and layout of the case.
Form factors for rack-mounted and blade servers may include
precise external dimensions as well, since these cases must
themselves fit in specific enclosures.

16. POWER SUPPLY
A power supply unit (PSU) is the component that supplies power to the other
components in a computer. More specifically, a power supply unit is typically
designed to convert general-purpose alternating current (AC) electric power from
the mains (100-127V in North America, parts of South America, Japan, and
Taiwan; 220-240V in most of the rest of the world) to usable low-voltage direct
current (DC) power for the internal components of the computer. Some power
supplies have a switch to change between 230 V and 115 V.

25. PARTS OF THE MOTHERBOARD
A CPU socket or slot is an electrical component that attaches to a printed circuit
board (PCB) and is designed to house a CPU (also called a microprocessor). It is
a special type of integrated circuit socket designed for very high pin counts. A CPU
socket provides many functions, including a physical structure to support the CPU,
support for a heat sink, facilitating replacement (as well as reducing cost), and
most importantly, forming an electrical interface both with the CPU and the PCB.
27. PERIPHERAL COMPONENT INTERCONNECT - part of the PCI Local
Bus standard and often shortened to PCI) is a computer bus for
attaching hardware devices in a computer.
Typical PCI cards used in PCs include: network cards, sound cards, modems,
extra ports such as USB or serial, TV tuner cards and disk controllers.
29. NORTH BRIDGE
also known as a Memory Controller Hub (MCH) or an Integrated Memory
Controller (IMC) in Intel systems (AMD, VIA, SiS and others usually use
'northbridge'), is one of the two chips in the core logic chipset on a PC
motherboard
FUNCTIONS :
The northbridge typically handles communications
among the CPU, RAM, BIOS ROM, and PCI
Express (or AGP) video cards, and the southbridge.
NORTH BRIDGE
also known as a Memory Controller Hub (MCH) or an Integrated Memory
Controller (IMC) in Intel systems (AMD, VIA, SiS and others usually use
'northbridge'), is one of the two chips in the core logic chipset on a PC
motherboard
30. SOUTH BRIDGE
FUNCTIONS :
also known as an I/O Controller Hub (ICH) in Intel systems
(AMD, VIA, SiS and others usually use 'southbridge'), is a chip that implements
the "slower" capabilities of the motherboard in a northbridge/southbridge
chipset computer architecture.
31. IDE
TYPES :
Integrated Drive Electronics - a computer hardware bus used primarily for hard
disk drives and optical drives (e.g. CD, DVD)
Parallel ATA (PATA) is an obsolete interface standard for the connection
of storage devices such as hard disks, solid-state drives, and CD-ROM drives
in computers.
Serial ATA (SATA or Serial Advanced Technology Attachment) is
a computer bus interface for connecting host bus adapters to mass storage
devices such as hard disk drives and optical drives.
34. CENTRAL PROCESSING UNIT (CPU)
is the portion of a computer system that carries out the instructions of
a computer program, and is the primary element carrying out the computer's
functions. The central processing unit carries out each instruction of the
program in sequence, to perform the basic arithmetical, logical, and
input/output operations of the system.
35.
36. RANDOM ACCESS MEMORY (RAM)
is a form of computer data storage. Today, it takes the form of integrated
circuits that allow stored data to be accessed in any order (i.e., at random).
"Random" refers to the idea that any piece of data can be returned in
a constant time, regardless of its physical location and whether or not it is
related to the previous piece of data. The word RAM is often associated
with volatile types of memory (such as DRAM memory modules), where the
information is lost after the power is switched off.

37. HARD DISK DRIVE (HDD)
is a non-volatile storage device for digital data. It features one or more
rotating rigid platters on a motor-driven spindle within a metal case. Data is
encoded magnetically by read/write heads that float on a cushion of air above
the platters.
39. PARTS OF A HARD DISK DRIVE
A hard drive consists of a number of platters on a spindle.
The platters are read and written to with heads for reading, writing, and
aligning.
Each platter has two sides.
Each side is divided into a number of rings called tracks. The tracks are
numbered 0 on the outside and usually go up to 1023 tracks.
All the tracks on the platter form a cylinder. Cylinders are also usually
numbered 0-1023.
Each track is divided into sectors. Sectors are the smallest chunk of bytes
usable on a hard drive. Sectors are usually 512 B but are always to the power
of two.
40. Contiguous tracks form clusters.
A hard disk has one MBR (Master Boot Record). A MBR holds the Partition Table
which says how a disk is partitioned into up to 4 primary partitions, or 3 primary
partitions and 1 extended partition
A primary partition has a specific file system (e.g. FAT or NTFS) and may even
have system file for a specific OS (e.g. W95 or WNT). A primary partition is
assigned a logical hard drive letter.
PARTS OF A HARD DISK DRIVE
43. PS/2 CONNECTORS
is used for connecting some keyboards and mice to a PC compatible computer
system. Its name comes from the IBM Personal System/2 series of personal
computers, with which it was introduced in 1987. The PS/2 mouse connector
generally replaced the older DE-9 RS-232 "serial mouse" connector, while the
PS/2 keyboard connector replaced the larger 5-pin DIN used in the IBM
PC/AT design.
44. USB PORTS
Universal Serial Bus (USB) is a specification to establish communication
between devices and a host controller (usually personal computers), developed
and invented by Ajay Bhatt while working for Intel. USB has effectively replaced
a variety of interfaces such as serial and parallel ports. USB can
connect computer peripherals such as mice, keyboards, digital
cameras, printers, personal media players, flash drives, Network Adapters,
and external hard drives.
45. SERIAL COMMUNICATION PORT
a serial port is a serial communication physical interface through which
information transfers in or out one bit at a time (contrast parallel
port). Throughout most of the history of personal computers, data transfer
through serial ports connected the computer to devices such as terminals and
various peripherals.
While such interfaces as Ethernet, FireWire, and USB all send data as a
serial stream, the term "serial port" usually identifies hardware more or less
compliant to the RS-232 standard, intended to interface with a modem or with a
similar communication device.
46. VGA PORT
Video Graphics Array (VGA) connector is a three-row 15-pin DE-
15 connector. The 15-pin VGA connector is found on many video cards,
computer monitors, and some high definition television sets. On laptop
computers or other small devices, a mini-VGA port is sometimes used in place
of the full-sized VGA connector. VGA connectors and cables
carry analog component RGBHV (red, green, blue, horizontal sync, vertical
sync) video signals, and VESA Display Data Channel (VESA DDC) data.
47. PARALLEL PORT
is a type of interface found on computers (personal and otherwise) for
connecting various peripherals. In computing, a parallel port is a parallel
communication physical interface. It is also known as a printer
port or Centronics port. The IEEE 1284 standard defines the bi-directional
version of the port, which allows the transmission and reception of data bits at
the same time.
48. ETHERNET LAN PORT
is a family of frame-based computer networking technologies for local area
networks (LANs). The name came from the physical concept of the ether. It
defines a number of wiring and signaling standards for the Physical Layer of
the Open Systems Interconnection (OSI) networking model as well as a
common addressing format and Media Access Control at the Data Link Layer.
50. POWER SUPPLY TROUBLESHOOTING
The first place to start is always confirming that the power supply
is operating properly. When you start troubleshooting a dead
computer, never ignore the possibility that the AC power to the
PC's power supply is at fault. Power supplies often fail gradually,
giving rise to symptoms that appear to be caused by individual
component failure. Many cheaper PC's ship with power supplies I
would basically describe as "disposable." If I had to choose one
part to blame the majority of intermittent failures in cheap PC's
on, it would be the power supply.
51.
52.
53. VIDEO CARD TROUBLESHOOTING
When we talk about troubleshooting video failures, we're usually
talking about no image at all on the display. The easy cases to
diagnose are those where the monitor or LCD isn't powering up
properly, or the PC not powering up. Video card failure isn't
uncommon, and video cards can lose their contact with the
motherboard, especially early AGP adapters which frequently
popped out of their slot. Video failure can also be due to
motherboard failure or to external interference, when it comes
to poor image quality.
60. COMMON COMPUTER PROBLEMS
1. Computer speed or performance has slowed.
Reasons why this happens to your computer:
Lack of maintenance, fragmented data, corrupted registry,
spyware, and unnecessary loading of computer programs
and services can surely affect your PC speed and
performance. Managing your programs and cleaning your
registry can easily boost your computer’s performance
speed up to 30%.
61. 2. Computer system freezes and blue screens of death.
Computer virus or spyware are maybe some of the reasons
why this is happening to your computer. Update your anti-
spyware immediately to avoid this kind of problem and
thoroughly scan your computer to see if it has any viruses or
spywares.
If that doesn’t work try to increase your Computer RAM to
help avoid computer freezes. By increasing the RAM you get
more use out your computer's computing power.
62. 3. The computer keeps on rebooting again and again.
This kind of problem is usually associated with hardware issue.
Faulty power supply is usually the cause of this problem.
Dirty or defective cooling fan is another reason why your
computer is rebooting spontaneously.
When your computer is trying to cool itself when the fan is
defective it automatically switches off. Dust that accumulated in
your computer can trap the heat inside which makes it hotter.
What you should do is to clean the fan and make sure that it is
running properly.
63. COMPUTER ERROR MESSAGES
Error Message: Disk Boot failure-insert system disk and press enter
CAUSES AND SOLUTIONS:
1: Ensure that your drives are empty
2: BIOS set up
3: New hard drive configuration
4: Hard drive not properly plugged in
5: Restore the corrupted system files notes
64.
65. Blue Screen of Death (also known as BSoD, blue screen), is caused by a fatal
system error and is the error screen displayed by the Microsoft Windows family of
operating systems upon encountering a critical error, of a non-recoverable nature,
that causes the system to crash.
The most common cause of blue screen errors
In reality, the most common cause of blue screen errors is a device driver
problem. Outdated, incorrect or corrupt drivers can cause the system to encounter
a STOP error, resulting in the BSOD.
SOLUTION: RE-INSTALL OUTDATED OR CORRUPTED HARDWARE DRIVERS
66. Check your system – run a virus scan and spy ware scan after updating your
definition files.
Run a memory test to check your computer’s RAM. Memory faults can easily cause
blue screen errors, so see if your RAM is error free. Vista and Windows have a
built-in option to test the memory, for XP you can use a program called memtest86.

118. NETWORK CABLING (Straight Through)
Unroll the required length of network cable and add a little extra wire, just
in case. If a boot is to be fitted, do so before stripping away the sleeve and
ensure the boot faces the correct way.
Step 1:
A straight-through cable is used to connect two different-layer devices
(e.g. a hub and a PC).
NETWORK CABLING (Straight Through)
A straight-through cable is used to connect two different-layer devices
(e.g. a hub and a PC).
119. Carefully remove the outer jacket of the cable. Be careful when stripping the
jacket as to not nick or cut the internal wiring. One good way to do this is to cut
lengthwise with snips or a knife along the side of the cable, away from yourself,
about an inch toward the open end. This reduces the risk of nicking the wires'
insulation.
Step 2:
120. Inspect the newly revealed wires for any cuts or scrapes that expose the
copper wire inside. If you have breached the protective sheath of any wire, you will
need to cut the entire segment of wires off and start over at step one.
Step 3:
Inspect the newly revealed wires for any cuts or scrapes that expose the
copper wire inside. If you have breached the protective sheath of any wire, you will
need to cut the entire segment of wires off and start over at step one.
Step 3:
121. Untwist the pairs so they will lay flat between your fingers. The white piece of
thread can be cut off even with the jacket and disposed.
Step 4:
122. Arrange the wires based on the wiring specifications you are following,
Then Crimp the RJ-45 after arranging the wires.

123. NETWORK CABLING (Crossover)
A crossover cable connects two devices of the same type, usually connected
asymmetrically, by a modified cable called a crosslink. Such distinction of
devices was introduced by IBM.
The crossing wires in a cable or in a connector adaptor allows:
connecting two devices directly, output of one to input of the other,
124. NETWORK SETUP (WINDOWS XP)
Peer to Peer Networking:
1. Right-click My Computer, then choose Computer name tab.
2. Under Computer name tab, click Change Button.
3. Change the Computer name according to your network naming
convention. E.g. PC1.
4. Make sure that the workgroup name of all the computer in the network
have the same workgroup name.
125. NETWORK SETUP (WINDOWS XP)
Basic elements of a computer network include:
hardware, software, and protocols. The interrelationship of these basic
elements constitutes the infrastructure of the network.
If we think of a network as roads, highways, rails, and other means of
transport, the network protocols are the "traffic rules." The network
protocols define how two devices in the network communicate.
126. 1. Start Network Setup via New Connection Wizard
