This is a serious flaw in a popular Internet encryption software called OpenSSL that has existed undetected (by 'white hat' hackers) since 2011. It not only exposes all current and future transmissions using the affected software but also previously-recorded encrypted information. For example, if someone with malicious intent was recording the encrypted information transmitted between a major financial website (e.g. PayPal) and its users, they could now use this bug to acquire the 'keys' to decrypt all the information, which would include credit cards, bank account numbers, the identity information to accompany those, usernames, passwords and anything else exchanged.

The fix has already been released but service providers need to manually apply the update so it will likely take quite a while for affected versions of the software to be phased out as word spreads about the bug.

My major concern with this is the ease it gives to foreign countries spying internationally. It is well-known that governments employ hackers in large numbers as part of their cyberwarfare teams and there's a very high chance that this bug was known about before information reached the public. This could also apply to major corporations and jew groups like the ADL and SPLC.

The best case scenario is the people that discovered this bug were the first to do so and it hasn't been in use for a protracted period of time. However, with the ability to decrypt previously recorded information, there's no telling what people were recording and trying to decrypt before this bug became available.
