What most bothers my mind of how easily those hackers seem to be able to break into those accounts security, specially since we are talking about accounts which belong to cryptocurrency companies and projects and would be protected with all security measures available, from double authentication or even biometric access if possible.
You got a point there but maybe there is an inside job that happened here? Again this is the product of greed or maybe misunderstanding of one of their teams to the other. So this is like their way or revenge to damage the reputation of the company but it can be less effective since people will only think that they got hacked.
Unfortunately, there will be people gullible enough to send their funds to those scammers believing it is an actual opportunity to double their money, only because the account indeed belongs to ripple.
I think these are the people who are still new on these schemes but they can always verify it and avoid the danger. If not, they are only paying for their lesson. I see that 100 XRP is the minimum to this scam giveaway. 100 XRP is like over $200. That isn't cheap, so it is definitely an expensive lesson for those who got tricked by it.
I personally doubt this is the result of a inside job from within the company, I lean towards the possibility of one of their employees getting fished and hackers getting access to the social media of the company so they can pull this scam off.
Also, the minimum amount to send to scammers is indeed a very expensive lesson, specially for someone who is new enough within the world of cryptocurrency to fall for something like this... I have seen people losing thousands of dollars and even tens of thousands (during the disaster of Terra-Luna), but those were rather experimented users who were seeking for yield of their savings, this is different, this is the classical scam how runs thanks to the overwhelming greed of some investors who cannot tell when something is to good to be true and stay away from it.
