Individual Prevention Policies

The exploit was most likely the result of Sup_55 providing their seed phrase to a scammer, installing malware on their computer, or approving a malicious transaction. Offline storage provides an alternative for a cryptocurrency user to massively reduce their risk.

Private keys can be obtained through seed phrases, mnemonics, private key files, mobile synchronization screens, wallet export features, wallet backups, etc... Never ever send these to anyone else who you do not intend to allow to take all of your money. Attackers will use a wide variety of tactics to convince you like pretending to be your wallet software, pretending they work for the wallet software, or asking you to screen share. Don't fall for them.

Any time untrusted software is being run is an opportunity for abuse. It is recommended to always interact with cryptocurrency in a fully controlled environment, which is an environment where you have understanding of every piece of software running there. Using a hardware wallet, spare computer with all software wiped, and/or virtual machine with only the needed software greatly reduces your attack surface. Take the time to verify downloaded files come from the correct and expected source and match available hashes if provided. Any time you encounter a new file, always check if it can contain executable code prior to using it.

Every approval on Web3 is an opportunity to lose all of the funds present in your wallet. Take the time to review the transaction in full. Fully check over the balance, permissions, and entire address which you are interacting with. Do not trust that your clipboard or any website front-end is guaranteed to provide an accurate address or transaction status. Always perform a test transaction prior to the first high-value transaction in any session.

Store the majority of funds offline. By offline, it means that the private key and/or seed phrase is exclusively held by you and not connected to any networked device. Examples of offline storage include paper wallets (seed phrase or key written down and deleted from all electronic media), hardware wallets, steel wallet devices, etc...

Platform Prevention Policies

Platforms have a responsibility to educate new users and ensure understanding. They can work together to create an industry insurance fund to assist affected users.

Never take for granted the limited knowledge of users of your service and their tendency to skip past provided information. It is recommended to design a simple tutorial and quiz for new users which explains the basics of seed phrases, strong password generation, secure two-factor authentication, common fraud schemes, how ponzi schemes work, as well as other risks which are unique to the cryptocurrency space. This tutorial and quiz should ensure their understanding and be a standard part of the sign-up or download process which is difficult or impossible to skip.

Work with other industry platforms to set up a multi-signature wallet with private keys held separately by delegate signatories from seven prominent platforms and services within the industry. Establish requirements for contributions by all platforms and services, designed to be affordable for small platforms yet large enough to cover anticipated breach events. Any breach event can be brought forth by a member platform or a petition of 100 signatures for consideration by the delegate signatories. A vote of 4 or more delegate signatures is required to release any funds, which could partially or fully restore lost funds based on their assessment.

For the full list of how to protect your funds as a financial service, check our Prevention Policies for Platforms guide.

Regulatory Prevention Policies

Regulators have a responsibility to educate their citizens and ensure understanding. Regulators can encourage platforms to create an industry insurance fund to assist affected users.

Create a standard tutorial and quiz for all new cryptocurrency participants, which is required to be completed once per participant. This tutorial and quiz should cover the basics of proper seed phrase protection, strong password generation, secure two-factor authentication, common fraud schemes, how to detect and guard against phishing attacks, how ponzi schemes work, as well as other risks which are unique to the cryptocurrency space.

Set up a multi-signature wallet with private keys held separately by delegate signatories from seven prominent platforms and services within the industry. Establish requirements for contributions by all platforms and services within the country, designed to be affordable for small platforms yet large enough to cover anticipated breach events. Any breach event can be brought forth by a member platform or a petition of 100 signatures for consideration by the delegate signatories. A vote of 4 or more delegate signatures is required to release any funds, which could partially or fully restore lost funds based on their assessment.
