BlockFi data breach could have been prevented, Bitcoin experts say

Another day, another prominent Bitcoin service breached. 

News broke out this morning that hackers had compromised accounts belonging to crypto lending firm BlockFi by using SIM swaps, a common tactic hackers use to essentially steal the identities of cell phone users by fooling cell providers. And the crypto community isn’t taking the news well.

The company said in an incident report sent to users that sensitive information from accounts, such as names, email addresses, dates of birth, physical addresses, and activity histories were revealed to the hackers.

According to BlockFi, however, the hackers were not able to access other personally identifiable data, including social security numbers, tax identification numbers, passports, licenses, passwords, bank account information, account preferences, and photo IDs.

Nevertheless, the news appears to have alarmed BlockFi clients and kicked up a storm of controversy on Twitter, especially among privacy-minded Bitcoiners.
