This hack was not done with private keys, but by disabling 2FA.
So says author of that article, Filip Poutintstev. To quote the title "Unknown Blockchain.com employee is stealing customers funds" but he provides zero evidence of that, just assumptions and nothing else. I don't say that whats written in article is impossible to happen, but still it would be good to provide some evidence for those claims otherwise it;s nothing but a clickbait title. Same thing he did in the article called
Reasons to avoid Bitcointalk where he wrote bunch of nonsense and lies.
On the other hand, I am not big fan of blockchain.com wallet and I stopped using it some time ago after having a lot of issue with sending/receiving funds. Last time it happened I had to export private key and move my funds to another wallet.
It's called logical deduction.
The facts are that it's impossible for anyone to do this theft other than Blockchain.com employee, because no one else can disable notifications about 2FA change.
Since you brought up the other article, perhaps you can tell which points exactly are false?
It's still not 100%, a proof will erase doubts about this. Hacks are not unusual in crypto, you probably have seen it all. If blockchain.com itself will be obligue to investigate, its where the proof must come from. I doubt they will present it here.
One thing that is very true though is that online wallets are always not safe. Whoever stole the coins, we don't have the chance of getting it back anymore. The only that we can do is become aware of the danger and not put our coins on online wallet like blockchain.com
