Sluggish haze safety and security team warns of EOS account safety threat. The team mentioned that the EOS budget designer strictly judges the node verification (at the very least 15 verification nodes) to educate the user that an account has been efficiently created. If it not effectively judged after that a phony account attack could take place.
How does the attack take place?
The assault can happen when a customer makes use of an EOS purse to sign up an account and also the purse triggers that the enrollment achieves success, however the judgment is not stringent, the account significance is not registered yet.

How to defend against the attack?
Poll the node as well as return the irreparable block information and after that prompt the success. The particular technical process consists of: push_transaction to get trx_id, demand interface ARTICLE/ v1/history/get _ transaction and also in the return criterion, block_num is less than or equal to last_irreversible_block, which is irreparable.
Lately, a blockchain safety and security company, PeckShield lately analyzed the security of EOS accounts and also found that some individuals were making use of a secret trick to major safety and security dangers. The located that the main reason for the issue is that the part of the secret trick generation device enables the individuals to make use of a weak mnemonic mix. And, the secret key that’s produced in this way is extra prone to “rainbow” attacks. It could also lead to the burglary of electronic assets.
PeckShield wrote, “The significance of the risk is caused by an inappropriate use third-party EOS key-pair generation devices, including yet not restricted to EOSTEA. With user-provided seeds, these devices considerably assist in customers to create their EOS key pairs.”
They likewise added a service stating, “… if a straightforward seed is selected (by the user) and also permitted (by the device), the created secrets could be subjected and also made use of by releasing the rainbow table attack (or dictionary assault).” They pointed out in their blog that in order to protect afflicted holders, PeckShield will certainly be launching a public service referred to as EOSRescuer.
