<h3>10-9-2014: PayPal accounts hacked with a click</h3>
<p>Yasser Ali reports a now patched vulnerability in PayPal that would
have allowed him to reset other user's passwords and take over their
accounts. This is unlikely to be the last vulnerability found in
account-based payment systems.<br>
In Taler, customers do not have accounts with usernames, passwords
or associated e-mail addresses. Instead, Taler uses reserves which
are represented by a private key on the owner's computer. Users
create a reserve by depositing currency at a Taler exchange, and can then
withdraw digital coins from that reserve using the respective private
key. There is no limit on the number of reserves a user can have, and
even hacking the Taler exchange would not provide an adversary with access to
user's reserves (as the Taler exchange does not have the private keys).
Stealing in Taler requires breaking into each customer's computer to
extract the reserve keys or the coins from the digital wallet.
