Blockchain Auditors Say $4m Crypto Theft Enabled By Logging Tech
Blockchain auditors have suggested the reason behind a massive $4 million hack on several crypto-currency wallet providers is a misconfiguration in a widely used event-logging technology.
Crypto-currency tokens Solana (SOL) and USD Coin (USDC) were among those stolen from Slope wallets by an unknown attacker, after the wallets were found to be leaking seedphrases in plaintext. Seedphrases are strings of randomly generated words used to recover crypto-currency wallets. They are considered secure, and only the owners are supposed to know what these strings are.
Blockchain auditors Zellic and OtterSec have both published the findings from their respective investigations, which are still ongoing, have suggested the reason behind a massive $4 million hack on several crypto-currency wallet providers is due to a misconfiguration in a widely-used event-logging technology.
Professional cyber criminals know that blockchain’s algorithms are secure and have busied themselves looking for other ways to manipulate and penetrate them.
Slope, Solana & Phantom Wallets
In a recent incident, the blockchain platform Solana reported that 7767 wallets were impacted during a security incident in which $4 million was stolen. In addition to Solana customers, Slope and Phantom users were also affected. While the cause of the exploit is unknown, Solana has said that hardware wallets were not affected in the incident and users are strongly encouraged to use this type of wallet. The firm says that engineers from several different operating environments are investigating the incident.
The attack against Solana is the latest in a series of attacks targeting the crypto currency industry and users are advised to take particular care in securing their profiles and wallets, such as revoking third-party permissions and setting up extra security measures.
Blockchain - An Immutable Ledger
Known as an "immutable ledger," blockchain is supposed to be impervious to bad actors and this is one of the reasons blockchain has become so popular is that its design prevents anyone from deleting or changing a record once it has been created.
This renders blockchain especially useful for crypto currency applications, where it’s important that records of spent money can’t be changed or deleted, as well as e-voting, financial records, manufacturing records, product provenance, and many other applications. However, the ownership blockchains for these coins and tokens are also vulnerable to type of hacking and fraud.
Blockchain’s auditors Zellic and OtterSec have concluded the issue stemmed from a misconfiguration in Sentry, an event-logging platform used by many websites and mobile apps in the industry, including the Slope wallet for iOS and Android. Other wallets also affected include Phantom, Solflare, and TrustWallet.
- Zellic said “any interaction in the app would trigger an event log. Unfortunately, Slope didn't configure Sentry to scrub sensitive info. Consequently, the seedphrases were leaked to Sentry”.
- According to OtterSec, anyone with access to Sentry could access users’ private keys, allowing them to recover wallets that don’t belong to them and transfer tokens to their own personal wallet.
Zellic’s research suggested that Slope had only been using Sentry for a week before the breach was confirmed. It also found it’s possible to scrub data that doesn’t need to be logged in Sentry via the platform’s software developer kit or via server-side scrubbing.
Almost 1,400 of the addresses in the exploit were present in Sentry logs, although this does not account for all the hacked addresses. The research suggests that there are thousands of additional wallets that contain crypto currency tokens and could currently be vulnerable to additional attacks from the still-unknown hacker.
Owners of a Slope wallet are strongly advised to transfer all tokens into a different method of storage as soon as possible, such as a hardware ledger or centralised exchange.
