  4. 4. UNTRUSTED PLACES
  5. 5. PROBLEM. WHAT/WHO MAKES US INSECURE? • Are we revealing everything about ourselves everywhere? • Perhaps • Don’t we know anything about security and privacy? • Perhaps • Aren’t app developers responsible for security fails? • Who said they’re not? They are! • They prefer not to tell about it only
  6. 6. https://www.itr.co.uk/mobile -app/ ITR RESEARCH RESULTS. WHY CONSUMER UNINSTALLED MOBILE APPS

  9. 9. FACTS ABOUT APP INSECURITY • At first glance, the VK Music app only displayed legitimate functionality – it played audio files uploaded to the social network. But further study showed that it also contained malicious code designed to steal VKontakte user accounts and promote certain groups on the social network. • https://securelist.com/blog/incidents/72458/stealing-to-the- sound-of-music/ • “In Russia will be kept of phone numbers, logins and passwords of users. Messages we do not store, they are on the devices of users,” Moscow representative of the company Viber said. According to the company’s lawyers, messengers also fall under the law which requires to store personal data of Russians on servers located on the territory of the country.
  10. 10. FACTS ABOUT APP INSECURITY • InstaAgent, an app that connects to Instagram and promises to track the people that have visited a user's Instagram account, appears to be storing the usernames and passwords of Instagram users, sending them to a suspicious remote server. • An app developer from Peppersoft downloaded InstaAgent -- full name "Who Viewed Your Profile - InstaAgent" -- and discovered it's reading Instagram account usernames and passwords, sending them via clear text to a remote server - instagram.zunamedia.com. • http://www.macrumors.com/2015/11/10/malicious-instaagent- instagram-app/
  11. 11. FACTS ABOUT APP INSECURITY • Researchers find data leaks in Instagram, Grindr, OoVoo and more. The problems include storing images and videos in unencrypted form on Web sites, storing chat logs in plaintext on the device, sending passwords in plaintext… • http://www.cnet.com/news/researchers-find-data-leaks-in-instagram- grindr-oovoo-and-more • Another Popular Android Application, Another Leak. We have found that another popular Google play app, “Camera360 Ultimate,” not only enhances the users’ photos but also inadvertently leaks sensitive data, which gives malicious parties unauthorized access to users’ Camera360 Cloud accounts and photos. • https://www.fireeye.com/blog/threat- research/2015/08/another_popular_andr.html
  12. 12. WHAT COMPANIES THINK ABOUT ‘QUOTES’ AND INSECURITY • Instagram said it's moving to encrypted communications for its images by moving to HTTPS, the secure version of the standard used to transfer Web data over the Internet. • They did it but it’s still affected to MITM attacks • "Message data is stored in an unencrypted format because the operating systems (both iOS and Android) provide data isolation that prevents apps from having their storage read by other apps. This is considered standard in the industry, and is completely safe," the Kik said. • Standard… it’s safe… just ROFL… and did you know there is way to root device without owner knowledge?
  13. 13. WHAT COMPANIES THINK ABOUT ‘QUOTES’ AND INSECURITY • SECURITY is core at 4Talk. Starting from secure phone number registration, to interaction only with confirmed personal contacts, to fully managing your account from any device you use. • Y2014 wasn’t protected at all • Y2015: Protected for Windows in-rest & transit, prevent MITM • Y2015-2016: Protected for Android in-transit only, prevent MITM • This app hasn’t PROXY FEATURE (!) So fun protection • Y2015: Not protected at all for Mac • Y2016: Network is protected (thanks Apple) for Mac • Y2015-2016: Not protected for iOS and Mac OS at all • Data Leakage is data that becomes available when you perform typical activities. Instead, Vulnerability is a weakness of program. Thus, Vulnerability ≠ Data Leakage, because no weakness in normal activities… • Average security support answer in regards of fail. Just spend small amount of money ($$) to steal the user data with fake networks in
  14. 14. WHAT COMPANIES THINK ABOUT ‘QUOTES’ AND INSECURITY • In its defense, AgileBits insisted that AgileKeychain was still secure, and noted that the format dates back to 2008 when the company was concerned about speed and battery drain problems caused by encryption. • http://appleinsider.com/articles/15/10/20/1password-to- change-file-formats-after-key-file-found-to-contain- unencrypted-data • If you browse to your .agilekeychain “file” on disk, you find that it is actually a directory. Inside this directory is a file named “1Password.html”.
  15. 15. PREVIOUS RESEARCH • I did many researches on mobile and app security. • First of them were about something average between OS and Apps – BlackBerry, Android. It was published and present around the world • 2013-2015 Researches • Cross OS apps - protection concepts, OS specifics per concept, outlines & remediation, EMM specifics • “We know Twitter & Dropbox are better secured than bank apps!” • http://www.slideshare.net/EC-Council/hh-yury-chemerkin • http://defcamp.ro/dc14/Yury_Chemerkin.pdf • In 2014 presented results cover ~700 apps • Also in 2015 • http://def.camp/wp- content/uploads/dc2015/Chemerkin_Yury_DefCamp_2015.pdf • In 2015 presented results cover ~700 apps • 2016 Current results: most interested cases (all up-to-dated prior

We make express reference to the fact that we do not record in logs communication contents or data regarding the accessed websites or the IP addresses. • In March 2012, CyberGhost had successfully passed an audit and verification conducted by QSCert for the implemented Information Safety Management System (ISMS) according to the international industrial standards ISO27001 and ISO9001. The certification confirms the high quality of the internal safety processes and is renewed yearly
  57. 57. ISO 27001, ISMS, ETC. • ISO27001 (and similar standards for non-IT areas) explicitly do not require "have you taken every sensible precaution to ensure it is", it is sufficient to have a policy that acknowledges that you haven't taken a bunch of very sensible precautions and that you simply accept the risks caused by that • If a company with a proper ISMS only accepts file uploads with unsecure FTP, it means they thought about this and decided either it's not their problem or they don't care
  58. 58. RESPONSIBLE DEVELOPER VS LAZY ONE • Apple (!) & Google (!) • QIWI – best app with own cryptography and has implemented all security features • Dropbox - has implemented all security features • App in the Air (network, in progress) • CyberGhost (network, in progress) • Asus Web Storage (pwd, in progress) • Sberbank (background fixing) • Hotels.Ru (network, in progress) • DeliveryClub (network, in progress) • AnywayAnyday (network, having fun with hardcoded ‘anyway’ 192bit  256bit key) • Evernote (network) • … everyone you saw in this slide or among my researches
  59. 59. PANDA SM MANAGER IOS APPLICATION - MITM SSL CERTIFICATE VULNERABILITY • "Panda Systems Management is the new way to manage and monitor IT systems." "Inventory, monitoring, management, remote control and reporting... All from a single Web-based console" (https://itunes.apple.com/us/app/panda-sm-manager/id672205099) • Timeline – Almost 1 Year (!) • July 19, 2015 - Notified Panda Security via security@pandasecurity.com, e- mail bounced July 20, 2015 - Resent vulnerability report to corporatesupport@us.pandasecurity.com & security@us.pandasecurity.com July 20, 2015 - Panda Security responded stating they will investigate July 31, 2015 - Asked for an update on their investigation August 3, 2015 - Panda Security responded stating that the issue has been escalated and is still being reviewed August 14, 2015 - Asked for an update on their investigation October 16, 2015 - Asked for an update on their investigation • … NO ANSWER … March 1, 2016 - Panda Security released version 2.6.0 which resolves this
  60. 60. ADVICES. YOU’RE DEVELOPER? DON’T CARE ABOUT SECURITY/PRIVACY? THEN YOUR CHOICE IS … • BlackBerry. Protects everything locally stored except public folders & external storage. Also it’s hardly to MITM except plain http traffic. Even for Android (!) • Windows Modern 10 apps. Anti-MITM protection on OS level by default (still researching it, also can’t confirm it for Android app support – Project Astoria) • iOS. Ok. Easy way to make user to install trusted fake certificate to MITM. Upgrade! Local app files on iOS < 8.3 could be accessed without jailbreak • Android. Fail. Easy way to make user to install trusted fake certificate to MITM. Some vendors prevent unlocking bootloader without user interaction to avoid root without his asking. But some doesn’t (!)
  61. 61. REMEDIATION: ANDROID • Follow security programming guide from Google • Call ‘setStorageEncryption’ API for locally stored files (new Android OS v5+) • Encrypt externally stored files on SD Card or Cloud (any OS) • Define when encryption signature doesn’t matter, else avoid it • Reduce using of ‘MODE_WORLD_READABLE ’ unless it really needs • Avoid hardcoded and debug tracks as much as possible (it’s easy to decompile) • Add extra protect beyond OS (encryption, wiping, etc.)
  62. 62. REMEDIATION : IOS • Follow security programming guide from Apple • Never store credentials on the phone file system. Use API or web scheme instead • Define when encryption signature doesn’t matter, else avoid it • Use implemented protection mechanism in iOS… • But … add extra protection layer beyond OS protection in case of jailbreak • Use any API and protection mechanisms properly but never default settings • Don’t forget to encrypt SQL databases
  63. 63. REMEDIATION : BLACKBERRY • Follow security programming guide from BlackBerry • Don’t store credentials in shared folders • Encrypt data stored in shared folders • Use implemented protection mechanism in BlackBerry… • But … add extra protection layer beyond just in case • Don’t forget to encrypt SQL databases • Don’t develop Android app-ports • Try to avoid using ported or Android native app under BlackBerry • Develop more and use native apps for BlackBerry 

REMEDIATION: WINMOBILE 10 • Credentials stored or transferred in plaintext locally. • Data usually stored or transferred structured file type that simplify an analysis • Signature-based encryption helps quickly decrypt data (depends on dynamically linked libraries) • Data stored in SQLite databases usually not encrypted • Keys may be hardcoded or put in data folder • Applications could be analyzed on Windows 10 Desktop via known methods like a desktop applications
  65. 65. REMEDIATION: WIN 10 • Credentials stored or transferred in plaintext locally. • Data usually stored or transferred structured file type that simplify an analysis • Signature-based encryption helps quickly decrypt data (depends on dynamically linked libraries) • Data stored in SQLite databases usually not encrypted • Keys may be hardcoded or put in data folder • Application data folder is access without any restrictions
  66. 66. REMEDIATION: MAC OS X • Credentials stored/ transferred in plaintext locally. • Data stored in a keychain without additional protection or encryption • Data usually stored or transferred structured file type that simplify an analysis • Signature-based encryption that helps to quickly decrypt data • Avoiding protection mechanism in iOS that leads to pure protection eventually • Data stored in SQLite databases usually not encrypted • Keys may be hardcoded • Application data folder is access without any restrictions
