paypal hack free no survey or download - paypal hack for ios - paypal latest hack add unlimited moneyToday 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.Phase 3[edit]*After fine-tuning PayPal's business model and increasing its domestic and international penetration on eBay, PayPal started its off-eBay strategy. This was based on developing stronger growth in active users by adding users across multiple platforms, despite the slowdown in on-eBay growth and low-single-digit user growth on the eBay site. A late 2003 reorganization created a new business unit within PayPal—Merchant Services—to provide payment solutions to small and large e-commerce merchants outside the eBay auction community. Starting in the second half of 2004, PayPal Merchant Services unveiled several initiatives to enroll online merchants outside the eBay auction community, including:[72]**Lowering its transaction fee for high-volume merchants from 2.2% to 1.9% (while increasing the monthly transaction volume required to qualify for the lowest fee to $100,000)*Encouraging its users to recruit non-eBay merchants by increasing its referral bonus to a maximum of $1,000 (versus the previous $100 cap)*Persuading credit card gateway providers, including CyberSource and Retail Decisions USA, to include PayPal among their offerings to online merchants.*Hiring a new sales force to acquire large merchants such as Dell, Apple's iTunes and Yahoo! Stores, which hosted thousands of online merchants*Reducing fees for online music purchases and other "micropayments"*Launching PayPal Mobile, which allowed users to make payments using text messaging on their cell phonesA charge a credit card company may assess to a customer’s account if the customer attempts to pay a credit card bill with a check that is returned unpaid.
