Mbinu za Msingi

Kila mazingira ya mawingu yana sifa zake za kipekee lakini kwa ujumla kuna mambo kadhaa ya kawaida ambavyo pentester anapaswa kuangalia wakati wa kupima mazingira ya mawingu:

Ukaguzi wa benchmark
Hii itakusaidia kuelewa ukubwa wa mazingira na huduma zinazotumika
Pia itakuwezesha kupata baadhi ya misconfigurations ya haraka kwa sababu unaweza kufanya sehemu kubwa ya vipimo hivi kwa kutumia zana za otomatiki
Services Enumeration
Pengine hutapata misconfigurations mingi zaidi hapa ikiwa ulifanya vizuri vipimo vya benchmark, lakini unaweza kupata baadhi ambayo havikutafutwa kwenye mtihani wa benchmark.
Hii itakuwezesha kujua kinachotumika hasa ndani ya mazingira ya cloud
Hii itasaidia sana katika hatua zinazofuata
Angalia mali zilizo wazi
Hii inaweza kufanywa wakati wa sehemu iliyotangulia, unatakiwa kubaini kila kitu kinachoweza kuwa wazi kwa Internet kwa namna fulani na jinsi kinavyoweza kufikiwa.
Hapa ninamaanisha infrastructure iliyofunguliwa kwa mikono kama instances zenye web pages au port nyingine zilizo wazi, na pia kuhusu cloud managed services ambazo zinaweza kusanidiwa kufunguliwa (kama DBs au buckets)
Kisha unapaswa kuangalia je rasilimali hiyo inaweza kufunguliwa au la (taarifa za siri? vulnerabilities? misconfigurations katika service iliyofunguliwa?)
Angalia ruhusa
Hapa unapaswa kubaini ruhusa zote za kila role/user ndani ya cloud na jinsi zinavyotumika
Je kuna akaunti nyingi zenye highly privileged (zinaweza kudhibiti kila kitu)? Funguo zilizotengenezwa hazitumiwi?... Zaidi ya haya ukaguzi ulipaswa kufanywa tayari katika vipimo vya benchmark
Ikiwa mteja anatumia OpenID au SAML au nyingine federation unaweza kuhitaji kuwauliza kwa taarifa zaidi kuhusu jinsi kila role inavyotengwa (si sawa role ya admin kuwekewa 1 user au 100)
Si vya kutosha kutambua ni watumiaji gani wana ruhusa za admin ":". Kuna ruhusa nyingi nyingine ambazo kulingana na huduma zinazotumika zinaweza kuwa za nyeti.
Zaidi ya hayo, kuna njia za potential privesc za kufuatilia kwa kutumia ruhusa. Mambo haya yote yanapaswa kuzingatiwa na itupe taratibu za privesc kadri iwezekanavyo kuripotiwa.
Angalia Integrations
Inawezekana sana kwamba integrations na mawingu mengine au SaaS zinatumika ndani ya mazingira ya cloud.
Kwa integrations za cloud unazochunguza na platform nyingine unapaswa taarifa nani ana access ya (ab)use hiyo integration na unapaswa kuuliza je kitendo kinachofanywa ni kiasi gani nyeti.
Kwa mfano, nani anaweza kuandika kwenye AWS bucket ambapo GCP inapata data kutoka (uliza jinsi kitendo kinavyoathiri GCP katika kushughulikia data hiyo).
Kwa integrations ndani ya cloud unazochunguza kutoka platform za nje, unapaswa kuuliza nani ana access kwa nje ya (ab)use hiyo integration na angalia jinsi data hiyo inavyotumika.
Kwa mfano, ikiwa service inatumia Docker image iliyohifadhiwa katika GCR, unapaswa kuuliza nani ana access ya kuibadilisha na ni taarifa zipi nyeti na access gani picha hiyo itaipata inapoendeshwa ndani ya AWS cloud.

Zana za Multi-Cloud

Kuna zana kadhaa ambazo zinaweza kutumika kujaribu mazingira tofauti ya mawingu. Hatua za usakinishaji na viungo vitaainishwa katika sehemu hii.

PurplePanda

Zana ya kutambua misconfigurations mbaya na privesc path katika mawingu na kati ya mawingu/SaaS.

bash

# You need to install and run neo4j also
git clone https://github.com/carlospolop/PurplePanda
cd PurplePanda
python3 -m venv .
source bin/activate
python3 -m pip install -r requirements.txt
export PURPLEPANDA_NEO4J_URL="bolt://neo4j@localhost:7687"
export PURPLEPANDA_PWD="neo4j_pwd_4_purplepanda"
python3 main.py -h # Get help

bash

export GOOGLE_DISCOVERY=$(echo 'google:
- file_path: ""

- file_path: ""
service_account_id: "some-sa-email@sidentifier.iam.gserviceaccount.com"' | base64)

python3 main.py -a -p google #Get basic info of the account to check it's correctly configured
python3 main.py -e -p google #Enumerate the env

Prowler

Inasaidia AWS, GCP & Azure. Angalia jinsi ya kusanidi kila mtoa huduma katika https://docs.prowler.cloud/en/latest/#aws

bash

# Install
pip install prowler
prowler -v

# Run
prowler <provider>
# Example
prowler aws --profile custom-profile [-M csv json json-asff html]

# Get info about checks & services
prowler <provider> --list-checks
prowler <provider> --list-services

CloudSploit

AWS, Azure, Github, Google, Oracle, Alibaba

bash

# Install
git clone https://github.com/aquasecurity/cloudsploit.git
cd cloudsploit
npm install
./index.js -h
## Docker instructions in github

bash

## You need to have creds for a service account and set them in config.js file
./index.js --cloud google --config </abs/path/to/config.js>

ScoutSuite

AWS, Azure, GCP, Alibaba Cloud, Oracle Cloud Infrastructure

bash

mkdir scout; cd scout
virtualenv -p python3 venv
source venv/bin/activate
pip install scoutsuite
scout --help
## Using Docker: https://github.com/nccgroup/ScoutSuite/wiki/Docker-Image

bash

scout gcp --report-dir /tmp/gcp --user-account --all-projects
## use "--service-account KEY_FILE" instead of "--user-account" to use a service account

SCOUT_FOLDER_REPORT="/tmp"
for pid in $(gcloud projects list --format="value(projectId)"); do
echo "================================================"
echo "Checking $pid"
mkdir "$SCOUT_FOLDER_REPORT/$pid"
scout gcp --report-dir "$SCOUT_FOLDER_REPORT/$pid" --no-browser --user-account --project-id "$pid"
done

Steampipe

Pakua na usakinishe Steampipe (https://steampipe.io/downloads). Au tumia Brew:

brew tap turbot/tap
brew install steampipe

bash

# Install gcp plugin
steampipe plugin install gcp

# Use https://github.com/turbot/steampipe-mod-gcp-compliance.git
git clone https://github.com/turbot/steampipe-mod-gcp-compliance.git
cd steampipe-mod-gcp-compliance
# To run all the checks from the dashboard
steampipe dashboard
# To run all the checks from rhe cli
steampipe check all

Kagua Miradi Yote

Ili kukagua miradi yote unahitaji kuunda faili gcp.spc inayobainisha miradi yote ya kujaribu. Unaweza kufuata tu maelekezo kutoka kwenye script ifuatayo

bash

FILEPATH="/tmp/gcp.spc"
rm -rf "$FILEPATH" 2>/dev/null

# Generate a json like object for each project
for pid in $(gcloud projects list --format="value(projectId)"); do
echo "connection \"gcp_$(echo -n $pid | tr "-" "_" )\" {
plugin  = \"gcp\"
project = \"$pid\"
}" >> "$FILEPATH"
done

# Generate the aggragator to call
echo 'connection "gcp_all" {
plugin      = "gcp"
type        = "aggregator"
connections = ["gcp_*"]
}' >> "$FILEPATH"

echo "Copy $FILEPATH in ~/.steampipe/config/gcp.spc if it was correctly generated"

SkyArk

Gundua watumiaji wenye vibali vya juu zaidi katika mazingira ya AWS au Azure yaliyoskaniwa, ikiwa ni pamoja na AWS Shadow Admins. Inatumia powershell.

bash

Import-Module .\SkyArk.ps1 -force

Cloud Brute

Chombo cha kutafuta miundombinu ya kampuni (lengo), mafaili, na apps kwenye watoa huduma wakubwa wa cloud (Amazon, Google, Microsoft, DigitalOcean, Alibaba, Vultr, Linode).

CloudFox

CloudFox ni chombo cha kutafuta exploitable attack paths katika miundombinu ya cloud (kwa sasa inasaidia tu AWS & Azure; GCP itakuja hivi karibuni).
Ni chombo cha enumeration kinachokusudiwa kukamilisha pentesting ya manual.
Haiundii wala hubadilisha data yoyote ndani ya mazingira ya cloud.

Grafu ya Shambulio

Stormspotter huunda “attack graph” ya rasilimali katika Azure subscription. Inawawezesha red teams na pentesters kuona attack surface na fursa za pivot ndani ya tenant, na huwapa defenders nguvu ya ziada kupanga na kuipa kipaumbele kazi za incident response haraka.

Office365

Unahitaji Global Admin au angalau Global Admin Reader (lakini kumbuka kuwa Global Admin Reader ni mdogo kidogo). Hata hivyo, vikwazo hivyo vinaonekana katika baadhi ya PS modules na vinaweza kuepukika kwa kufikia vipengele kupitia programu ya wavuti.
