Unit Testing
// lib/greeter.dart class Greeter { final Greeting greeting; Greeter(this.greeting); String greet(String name) { return '${greeting.phrase}, $name!'; } } // An example of a collaborator that can be mocked class Greeting { final String phrase; const Greeting(this.phrase); }
// test/unit/greeter_test.dart import 'package:quark/quark.dart'; export 'package:quark/init.dart'; import 'package:greeter/greeter.dart'; // Clean test double declaration inspired by Mockito class GreetingDouble extends TestDouble implements Greeting {} class GreeterTest extends UnitTest { @test itGreetsAPerson() { // Creation using test double final greeting = new GreetingDouble(); final greeter = new Greeter(greeting); // The greeting will return "Yo" when(greeting.phrase).thenReturn('Yo'); // Make the assertion expect(greeter.greet('buddy'), 'Yo, buddy!'); // Verify that the phrase was fetched from the greeting. verify(greeting.phrase).wasCalled(); } }
Integration Testing with Gherkin Features!
# test/integration/welcome_on_home_screen.feature Feature: Welcome message on the home screen Scenario: Not logged in Given I'm not logged in When I visit the home page Then I expect to see "Hello, Guest!"
To write the implementations of feature steps, extend the class and
and annotate with the annotation.
// test/integration/welcome_on_home_screen_test.dart // The TestOn annotation and browser.dart export enables // reading features by relative URI. @TestOn('browser') export 'package:quark/browser.dart'; // There is also a vm implementation. // @TestOn('vm') // export 'package:quark/vm.dart'; import 'package:quark/quark.dart'; export 'package:quark/init.dart'; @Feature('welcome_on_home_screen.feature') // The Gherkin can also be written inline and can then be run in both // the browser and the vm. // @Feature(''' // Feature: ... // ''') class WelcomeMessageOnTheHomeScreenTest extends IntegrationTest { @Given("I'm not logged in") imNotLoggedIn() {} @When("I visit the home page") iVisitTheHomePage() {} @Then("I expect to see \"(.*?)\"") iExpectToSee(String message) {} }
If there are steps in the feature that have no implementation in the test, the test runner
will print out snippets that can be copied into the test. Simple!
Why Quark?
Android malware analysis engine is not a new story. Every antivirus company has their own secrets to build it. With curiosity, we develop a malware scoring system from the perspective of Taiwan Criminal Law in an easy but solid way.
We have an order theory of criminal which explains stages of committing a crime. For example, crime of murder consists of five stages, they are determined, conspiracy, preparation, start and practice. The latter the stage the more we’re sure that the crime is practiced.
According to the above principle, . We developed five stages to see if the malicious activity is being practiced. They are 1. Permission requested. 2. Native API call. 3. Certain combination of native API. 4. Calling sequence of native API. 5. APIs that handle the same register. We not only define malicious activities and their stages but also develop weights and thresholds for calculating the threat level of a malware.
Malware evolved with new techniques to gain difficulties for reverse engineering. Obfuscation is one of the most commonly used techniques. In this talk, we present a Dalvik bytecode loader with the order theory of android malware to neglect certain cases of obfuscation.
Our Dalvik bytecode loader consists of functionalities such as 1. Finding cross reference and calling sequence of the native API. 2. Tracing the bytecode register. The combination of these functionalities (yes, the order theory) not only can neglect obfuscation but also match perfectly to the design of our malware scoring system.

Install with DevStack and Neutron
-
Ensure you have a user already with sudo rights. If you need one, do this as root:
/usr/sbin/adduser stack echo "stack ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers
-
Switch to user with sudo rights:
sudo su - stack # or whatever user you already have (instead of stack)
-
Clone devstack:
git clone https://github.com/openstack-dev/devstack
-
Go into devstack folder:
cd devstack
-
Create the local.conf configuration file that DevStack needs (localrc is inside it now) with Neutron as an anabled service (NOTE: This notation is explained here):
] DATABASE_PASSWORD=password ADMIN_PASSWORD=password SERVICE_PASSWORD=password SERVICE_TOKEN=password RABBIT_PASSWORD=password # Enable Logging LOGFILE=/opt/stack/logs/stack.sh.log VERBOSE=True LOG_COLOR=True SCREEN_LOGDIR=/opt/stack/logs # Pre-requisite ENABLED_SERVICES=rabbit,mysql,key # Horizon (always use the trunk) ENABLED_SERVICES+=,horizon HORIZON_REPO=https://github.com/openstack/horizon HORIZON_BRANCH=master # Nova ENABLED_SERVICES+=,n-api,n-crt,n-obj,n-cpu,n-cond,n-sch IMAGE_URLS+=",https://launchpad.net/cirros/trunk/0.3.0/+download/cirros-0.3.0-x86_64-disk.img" # Glance ENABLED_SERVICES+=,g-api,g-reg # Neutron ENABLED_SERVICES+=,q-api,q-svc,q-agt,q-dhcp,q-l3,q-lbaas,q-meta,neutron # Cinder ENABLED_SERVICES+=,cinder,c-api,c-vol,c-sch # Tempest ENABLED_SERVICES+=,tempest
-
Remove Python’s six packge:
sudo rm -f /usr/lib/python2.7/dist-packages/six.py /usr/lib/python2.7/dist-packages/six.pyc
# Old version of six package in /usr/lib/python2.7/dist-packages/ crashes
# quark server -
Install Devstack:
./stack.sh
-
Install aiclib:
sudo pip install aiclib # the reason for sudo here is if you don't you'll get permission denied when it tries to install to /usr/local/lib/python2.7/dist/packages
-
Install quark:
cd /opt/stack #the folder where devstack installed all the services git clone https://github.com/rackerlabs/quark cd quark sudo python setup.py develop # the reason for sudo here is if you don't you'll get permission denied when it tries to install to /usr/local/lib/python2.7/dist/packages
-
Validate quark installed:
pip freeze | grep quark # should see something like: # -e git+http://github.com/rackerlabs/quark@ff5b05943b44a44712b9fc352065a414bb2a6bf9#egg=quark-master
-
Now edit the /etc/neutron/neutron.conf file to setup Quark as the core plugin:
vim /etc/neutron/neutron.conf # Search for line containing 'core_plugin = ' and replace it with # 'core_plugin = quark.plugin.Plugin' # # Search for line containing 'service_plugins = ' and remove # 'neutron.services.l3_router.l3_router_plugin.L3RouterPlugin,' from # service plugins list
-
Stop Neutron by going into the screen session and going to the q-svc window and pressing ctrl-C:
screen -r # or go into devstack clone and then type ./rejoin-stack.sh # press ctrl+6 to go to q-svc window ctrl+C
-
Go back into screen and restart neutron (q-svc window):
screen -r stack # or go into folder where you cloned devstack then type ./rejoin-stack.sh # if screen command returns 'Cannot open your terminal /dev/pts/0' execute 'sudo chmod o+rwx /dev/pts/0' # go to q-svc window (ctrl+a, 7 currently does it) # previous command that devstack used to start neutron should be in history, press up arrow key to see it
-
You shouldn’t receive any errors. To validate Quark has started up, you can scroll up in q-svc screen window (ctrl+a, esc, page-up) and look for the following lines:
DEBUG neutron.service core_plugin = quark.plugin.Plugin ... DEBUG neutron.service QUARK.default_ipam_strategy=ANY DEBUG neutron.service QUARK.default_net_strategy={} DEBUG neutron.service QUARK.default_network_type=BASE DEBUG neutron.service QUARK.ipam_driver=quark.ipam.QuarkIpam DEBUG neutron.service QUARK.ipam_reuse_after=7200 DEBUG neutron.service QUARK.net_driver=quark.drivers.base.BaseDriver DEBUG neutron.service QUARK.strategy_driver=quark.network_strategy.JSONStrategy
Easy to Use and Reading Friendly Report
Quark is very easy to use and also provides flexible output formats. There are 6 types of output reports: detail report,
call graph, rules classification, summary report, label-based report, behaviors comparison radar chart. Please see below for more details.
Detail Report
This is how we examine a real android malware (candy corn) with one single rule (crime).
$ quark -a 14d9f1a92dd984d6040cc41ed06e273e.apk -d
and the report will look like:
There is the possibility to select only one label to filter the rules:
quark -a 14d9f1a92dd984d6040cc41ed06e273e.apk -d network
There is also the possibility to select only one rule:
quark -a 14d9f1a92dd984d6040cc41ed06e273e.apk -d 00058.json
Call Graph for Every Potential Malicious Activity
You can add the option to the quark command, and you can
get the call graph (only those rules match with 100% confidence)
quark -a Ahmyth.apk -s -g
Rules Classification
You can add the option to the quark command, and you can
output the rules classification with the mutual parent function (only those rules match with 100% confidence).
quark -a Ahmyth.apk -s -c
Summary Report
Examine with rules.
quark -a 14d9f1a92dd984d6040cc41ed06e273e.apk -s
There is the possibility to select only one label to filter the rules:
quark -a 14d9f1a92dd984d6040cc41ed06e273e.apk -s network
There is also the possibility to select only one rule:
quark -a 14d9f1a92dd984d6040cc41ed06e273e.apk -s <path_to_rule_folder>/00058.json
(If you want to select one of the rules of Quark-Rule, the default path to Quark-Rule is .)
Check which topic (indicated by labels) of the malware is more aggressive.
quark -a Ahmyth.apk -l detailed
Behaviors Comparison Radar Chart
With the following command, you can compare different APK actions based on the max confidence of rule labels and generate
a radar chart.
quark -a first.apk -a second.apk -C
Parallelizing Quark
Now Quark supports multiprocessing for analyzing APKs parallelly, by adding the option and set the number of processes. (the default is the number of CPUs in your computer.)
quark -a Ahmyth.apk -s --multi-process 4
Upcoming unstable feature
Now Quark also supports Rizin as one of our Android analysis frameworks. You can use option with to enable the Rizin-based analysis library.
quark -a Ahmyth.apk -s --core-library rizin
Сравнение Биткоина и Кварка
Сравнение сходств и различий Биткоина и форка Кварке будет происходить по основным параметрам, которые интересуют майнеров:
- Безопасность. Так как ВТС был криптовалютой-пионером, в его системе безопасности много брешей, и она не справляется с полученной нагрузкой. Для шифрования используется SHA-256, который уже долгое время попадает под экспертную и пользовательскую критику за свою уязвимость. В свою очередь Quark использует усовершенствованную структуру защиты, о которой говорилось в предыдущем разделе. Она состоит из 6 современных алгоритмов, которые продолжают функционировать, даже если из строя выведен один, а также из 9 раундов хэширования. В плане безопасности Биткоин проигрывает Кварку.
- Майнинг. В начале своего пути ВТС был «ходовой» криптовалютой, которую можно было майнить даже на откровенно средних пользовательских устройствах. Однако с ростом рыночной капитализации и популярности, требования к оборудованию и стартовым вложениям начали расти. На данный момент начать добывать «биток» с нуля без крупных капиталов и дорогостоящих GPU-ферм – невозможно. Единственная альтернатива – облачные сервисы, которые взымают серьезные комиссии. В период полного функционирования у системы Quarkcoin требования были гораздо лояльнее. Блоки генерировались в 20 раз быстрее, чем у прямого конкурента, но это, несмотря на пользу для начинающих майнеров, привело проект к провалу. Из-за перемайна за полгода было добыто 247 миллионов единиц, поэтому разработчикам пришлось заложить искусственную инфляцию, чтобы в последующие годы выпускать по 1 миллиону монет. С одной стороны это можно считать плюсом, так как вероятность превратить майнинг Кварка в «гонку вооружений» свелась к нулю, но с другой стороны это привело к обесцениванию валюты и полному упадку существующей системы.
- Скорость. В плане скорости обработки транзакций Биткоин уступает практически всем перспективным проектам. Переводы исполняются в рамках непозволительно долгих сроков – минимум 10 минут и до нескольких часов (а в случае с перегруженностью серверов во время сильных скачков стоимости – до суток). Именно этот фактор отвернул многих пользователей ВТС в сторону других «шустрых» криптовалют. В свою очередь среднее время подтверждения транзакции в сети QRK не превышает отметки в 40 секунд.
- Распределение. По этому параметру Биткоин также уступает Кварку по всем фронтам. Постоянный рост требований и запросов системы к современному оборудованию урезал аудиторию битка до маленькой группы людей, владеющей 85% всех криптовалютных капиталов (большинство из которых являются резидентами азиатских стран). АСИК-оборудование обходится дорого не только на этапе покупки, но и в процессе обслуживания. Минимальные стартовые затраты для начала майнинга превышают отметку в 10 000 долларов США. Quark же в основу идеи заложил доступность добычи для всех, в том числе и для владельцев производительных персональных компьютеров. Это подтверждается рядом факторов: основные «запасы» крипты находятся в руках не ограниченного небольшого круга пользователей, а у тысяч людей со всего мира, а также тем моментом, что большинство монет (247 миллионов) было добыто за короткий промежуток времени – за 6 месяцев. Простота и доступность майнинга снизила рыночную стоимость криптовалюты до рекордно низких отметок.

- Squid Inking: when attacked, Squids will shoot ink at the attacker, giving them Blindness. Introduced in r1.3-115.
О проекте
Криптовалюта Quark основана летом 2013 года разработчиком Max Guevara. Как базу для разработки он взял исходный код популярного Биткоина, усовершенствовал и лишил главных недостатков – преимущественно «пробелов» в безопасности. Защите валюты было уделено больше всего внимания. Для проекта Max Guevara выбрал кодирование транзакций при помощи шести полуавтономных алгоритмов и девяти «кругов» хэширования.
Такая сложная структура обеспечила стабильность и устойчивость к хакерским атакам. Благодаря ей система функционирует, даже если строя выходит один алгоритм шифрования.
Это сделало Quark лидером по безопасности среди электронных валют состоянием на 2013 год. Пользователи могут быстро и без проблем расплачиваться монетами за покупки, и переводить средства в любую точку земного шара за считанные секунды (что в двадцать раз быстрее, чем у «прародителя» крипты – Биткоина).
В 2013 году Quarkcoin на фоне растущей популярности занял четвертое место по рыночной стоимости среди функционирующих крипто-проектов. Блоки на тот момент генерировались в 20 раз быстрее, чем у BTC, что сделало Кварк легкой добычей для предприимчивых майнеров. Монеты добывались легко, а на некоторых ценовых скачках сотни пользователей преумножили свои капиталы в сотни раз.
После ошеломляющего успеха проекта ждал ошеломляющий провал. С 2014 года курс криптовалюты Quark застыл на отметке меньше цента, и этому показателю не суждено вырасти. Его можно не рассматривать как источник для инвестирования.
