free easy paypal hack site – how to hack paypal accounts 2017 – paypal hack tool apkToday I am going to publicly disclose a critical vulnerability I have found during my research in PayPal, This vulnerability enabled me to completely bypass the CSRF Prevention System implemented by PayPal, The vulnerability is patched very fast and PayPal paid me the maximum bounty they give ;).**1- Reusable CSRF Token:*The CSRF token “that authenticate every single request made by the user” which can be also found in the request body of every request with the parameter name “Auth” get changed with every request made by user for security measures, but after a deep investigation I found out that the CSRF Auth is Reusable for that specific user email address or username, this means If an attacker found any of these CSRF Tokens, He can then make actions in the behalf of any logged in user.*Hmm, it seems interesting but still not exploitable, as there is no way for an attacker to get the “Auth” value from a victim session.**2- Bypassing the CSRF Auth System:*The CSRF Auth verifies every single request of that user, So what If an attacker “not logged in” tries to make a “send money” request then PayPal will ask the attacker to provide his email and password, The attacker will provide the “Victim Email” and ANY password, Then he will capture the request, The request will contain a Valid CSRF Auth token Which is Reusable and Can authorise this specific user requests. Upon Further Investigation, We have found out that an Attacker can obtain the CSRF Auth which can be valid for ALL users, by intercepting the POST request from a page that provide an Auth Token before the Logging-in process, check this page for the magical CSRF Auth “ At this point the attacker Can CSRF “almost” any request on behalf of this user.*Through examination of the password change process, I have found that an attacker can NOT Change the victim password without answering the Security Questions set by user, Also the user himself can NOT change the security questions without entering the password!**3- ByPassing the Security Questions Change:*Screen Shot 2014-08-13 at 12.20.52 AM*The initial process of “setting” security questions is not password protected and is reusable*After further investigation, I have noticed that the request of setting up the security questions “which is initiated by the user while signing up” is not password-protected, and it can be reused to reset the security questions up without providing the password, hence, Armed with the CSRF Auth, an attacker can CSRF this process too and change the victim’s Security questions.**At this point, An attacker can conduct a targeted CSRF attack against PayPal users and take a full control over their accounts. Hence, An attacker can CSRF all the requests including but not limited to:**1- Add/Remove/Confirm Email address*2-Add fully privileged users to business account*3- Change Security questions*4- Change Billing/Shipping Address*5- Change Payment methods*6- Change user settings(Notifications/Mobile settings) ………… and more.*To automate the whole process, I have coded a Python interactive server to demonstrate how an attacker can exploit this vulnerability in a real-life scenario attack.Spin-off from eBay[edit]*It was announced on September 30, 2014, that eBay would spin off PayPal into a separate publicly traded company, a move that was demanded already in 2013 by activist hedge fund magnate Carl Icahn. The spin-off was completed on July 18, 2015.[46][47][48] Dan Schulman is the current President and CEO, with former eBay CEO John Donahoe serving as chairman.[45]**Acquisition of Xoom Corporation[edit]*On July 1, 2015, PayPal announced that it was acquiring digital money transfer company Xoom Corporation. PayPal spent $25 a share in cash to acquire the publicly traded Xoom, or about $1.09 billion. The deal was closed in the fourth quarter of 2015. The move strengthened PayPal’s international business, giving it access to Xoom’s 1.3 million active U.S. customers that sent about $7 billion in the 12 months ending on March 31 to people in 37 countries.[49][50]**PayPal.Me[edit]*On September 1, 2015, PayPal launched their peer-to-peer payment platform “PayPal.Me,” a service that allows users to send a custom link to request funds via text, email, or other messaging platforms.[51] Custom links are set to be structured as PayPal.me/username/amountrequested.[51] PayPal.Me was launched in 18 countries including United States, United Kingdom, Germany, Australia, Canada, Russia, Turkey, France, Italy, Spain, Poland, Sweden, Belgium, Norway, Denmark, Netherlands, Austria and Switzerland.[52] PayPal had 170 million users, as of September 2015, and the focus of PayPal.Me was to create a mobile-first user experience that enables faster payment sharing than PayPal’s traditional tools.[51]**In June 2016, it was announced that PayPal had joined the Fortune 500 fo
