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.

skeptical about what you believe and pass along.
12. MACINTOUCH SAYS…
Myth I read it on Macintouch (or on Apple’s Forums,or
at…) say…, so it must be true!
FACT Macintouch and other forums provide access
to useful information but are also sources of
outdated memes and misunderstood concepts. Be
skeptical about what you believe and pass along.
FACT Nobody believes their system could be the
cause of a problem—it must be a bug!
14. MACINTOUCH SAYS…
Myth There are 20 posts on Macintouch saying… so it
must be a major issue! (Why isn’t Apple doing anything
about it?)
15. MACINTOUCH SAYS…
Myth There are 20 posts on Macintouch saying… so it
must be a major issue! (Why isn’t Apple doing anything
about it?)
FACT Satisfied customers don’t post in proportion
to those having issues so the number of users
actually experiencing a given problem is often
exaggerated on forums. Again, be cautious before
jumping to conclusions and spreading false memes.

23. ZAP THE “PRAM”
Myth Restarting with CMD-OPT-P-R will fix it.
FACT This was more often true prior to OS X
which stores most of it’s parameters in Plists, not
Parameter RAM (or NVRAM for open firmware
computers). Most issues won’t be magically
repaired by zapping PRAM.

27. REBUILD THE DESKTOP
Myth Then a “CMD-OPT” restart must fix it.
FACT In the “Classic” OS, the desktop database
was a special invisible file containing associations
between icons and file types. Your OS X desktop is
a regular directory within your home folder with no
special features.
29. REBUILD THE DESKTOP
However the OS X Launch Services Database
“records all of the pertinent information about
applications and the kinds of document files and
URLs they are capable of opening. […] Launch
Services can then use this information to determine
the preferred application for opening a given
document file or URL.”

35. PARTITIONING
Myth I should always partition my system drive.
FACT There are valid reasons for partitioning
hard drives but most reasons for regular users to do
so are based on out-dated notions.

Myth I should always partition my system drive.
FACT There are valid reasons for partitioning
hard drives but most reasons for regular users to do
so are based on out-dated notions.
FACT If you don’t understand why you’re
partitioning, you probably don’t need to.
38. 10% Solution
Myth I need to leave 10% of my hard disk free or my data
will become corrupt. (Or the OS will freeze.)
39. 10% Solution
Myth I need to leave 10% of my hard disk free or my data
will become corrupt. (Or the OS will freeze.)
FACT It’s true that drives shouldn’t be crammed
to capacity but keeping 10% free on a large data
drive is leaving money on the table.
However you do want to leave free space at least
equivalent to the amount of physical RAM on your
System or swap disk.
41. DEFRAGMENTING A DRIVE
Myth My machine is running slowly, I should defragment
my hard disk to speed things up.
42. DEFRAGMENTING A DRIVE
Myth My machine is running slowly, I should defragment

the drive is freshly formatted.

FACT Anti-Virus software can have a negative
impact on your systems performance.
56. ANTI-VIRUS SOFTWARE
Myth Apple just released a tech note suggesting that I install
anti-virus software
FACT “We have removed the KnowledgeBase article because it
was old and inaccurate. The Mac is designed with built-in
technologies that provide protection against malicious software
and security threats right out of the box. However, since no
system can be 100% immune from every threat, running anti-
virus software may offer additional protection.”
Apple spokesman Bill Evans to TidBITS.

Myth Permissions go bad over time
FACT Permissions only change if something
changes them. This was more common prior to
10.3—primarily due to poorly written third-party
installers.

FACT “Repairing” merely sets the permissions of
certain files to the values specified by a Bill of
Materials (.bom) file within /Library/Receipts
76. REPAIR PERMISSIONS
Myth Repair permissions before and after any software
update or installation.
FACT We can thank our friends at MacFixIt (and a
misguided Macintouch contributor) for perpetuating
this meme. Apple does not recommend this.

80. REPAIR PERMISSIONS
Myth Apple recommends repairing permissions as a routine
maintenance task.
FACT No they don’t. The meme might be based
on this KnowledgeBase article:

(Note the title. This is a step in repairing a specific
problem not a maintenance task.)
83. REPAIR PERMISSIONS

to repair permissions if you believe a problem
might be the result of a file permissions issue.

can sometimes be repaired by downloading and
running the full installer.
91. Curse of rev 1.0
Myth Don’t ever buy rev. 1.0 of Apple hardware because it

92. Curse of rev 1.0
Myth Don’t ever buy rev. 1.0 of Apple hardware because it

FACT A Macintouch favorite. Jeff ’s 1.0 iPhone &
TiBook were without major flaws. His “mature”
iMac had serious issues (which Apple repaired—
twice) Make your decision based on your wants,
needs and personal assessment of the risks and
rewards, not a rule-of-thumb.

95. HACKING THE SYSTEM
Myth The new version of xyz.library breaks pdq.app so I
should install the previous version of the library manually.
FACT You still don’t believe what we’re saying
about MacFixIt, do you? While such hacking may in
fact produce a “fix” for your problem, the
“Frankensystem” you create may exhibit other
problems in the long run. Be wary of such “fixes.”
98. RAID
Myth My data is on a RAID so I don’t need a backup.
FACT RAID is not a backup. Your RAID unit can
be damaged or stolen. The data, even redundantly
written to disk, is still vulnerable.
101. APPLE’S DISK UTILITY
Myth Disk Utility sucks. It will make my problems worse.
FACT Disk Utility is a useful tool and, while it
doesn’t fix every problem, it fixes some things that
other utilities can’t.
103. DISKWARRIOR
Myth DiskWarrior is a last resort because it may cause me
to lose files. I should do X, Y and Z before running it.
104. DISKWARRIOR
Myth DiskWarrior is a last resort because it may cause me
to lose files. I should do X, Y and Z before running it.
FACT DiskWarrior should be one of your first line
tools in tracking down disk/directory related
problems—and is more likely to be effective if used before
you muck with the sick drive. Just be sure that the version
of DW you are using is compatible with version of
the OS you’re running.
