<\/p>\n

\n

Impacted configurations:<\/b> All smart contract wallets established using Ethereum Wallet \u00a0Frontier, version 0.4.0 (Beta 7) or earlier<\/em>. Wallets created with Ethereum Wallet 0.5.0 and all subsequent releases after March 3, 2016, are unaffected.<\/span><\/p>\n

<\/p>\n

Probability<\/b>: Low<\/span><\/p>\n

<\/p>\n

Impact Level<\/b>: High<\/span><\/p>\n

<\/p>\n

Overview:<\/h2>\n

Refrain from utilizing wallet contracts or the owner accounts of wallets that were generated by Ethereum Wallet 0.4.0 or earlier. Engaging with a malicious contract may result in loss of ownership of your wallet contract. Establish a new wallet and transfer your assets.<\/span>
\n<\/p>\n

How to ensure maximum security??<\/h3>\n

Avoid using compromised wallet contracts, AND\u00a0the associated owner\u00a0accounts of these wallets when sending ether or interacting with unfamiliar contracts!
\nIf you refrain from using these accounts and wallets, and upgrade your wallet as\u00a0<\/strong>outlined here<\/a>, you will be safe!<\/b>
\n<\/p>\n

Details:<\/h2>\n

A vulnerability was identified that influences smart contract wallets created before the Homestead release (Frontier phase). The risk arises if an affected wallet engages with a malicious contract OR if the owner account of a compromised wallet connects with a malicious contract that is aware of their wallet address. An attacker can then mimic the owner, allowing them to misappropriate funds or tokens and alter the ownership of the wallet.<\/span>
\n<\/p>\n

As long as you do not use your wallet and owner accounts with unfamiliar contracts, you are secure!<\/strong><\/p>\n

<\/p>\n

Receiving Ether and sending Ether to non-contract accounts is permissible.<\/span><\/p>\n

<\/p>\n

Moreover, if your wallet is set up with multisig, your security is enhanced, as the attacker would need to compel all owners to send to malicious contract(s).<\/span><\/p>\n

Recommended solution:<\/h2>\n

We advise that if you established a wallet using the affected versions, you undertake one of these measures:<\/span>
