Solana Wallets Caught in a Phishing Signature Attacks

The post Solana Wallets Caught in a Phishing Signature Attacks appeared first on Coinpedia Fintech News

The latest fraud incident in the Solana ecosystem is phishing in the form of apparently legitimate signature requests according to Scam Sniffer, a web3 anti-scam firm. The problem originates from Solana’s fast transaction speed because it leads to a divergence between emulated wallet states and real-world states. That is, there is a window of opportunity to mask more ill-intentioned actions and steal money from individuals’ wallets without causing suspicion for some time.

Exploit description

It takes the form of phishing sites presenting routine signature requests. However, once signed, these requests are designed to change ownership of the victims’ accounts to wallet drainers. These are not new tactics, though have become more refined. 

Security firm Blowfish has reported similar incidents in the past, and these attacks explain how malicious parties take advantage of Solana’s distinct transaction processing behaviour to avoid wallet emulation.  

The Recent Case Indicates a New Threat

A recent case that relates to this exploit was provided by cybersecurity expert @evilcos. Users are always enticed by Fake sites that ask for permission to carry out some operations. These approvals, which at first glance are innocuous, create the conditions under which attackers can drain funds and tokens into their accounts.  

Here Are a Few Steps to Stay Safe

We encourage the users to be very careful when using external sites that they are not familiar with. Key safety measures include:  

1. Avoid signing suspicious requests: Do not allow any transactions to be approved that may look awkward or unnecessary to enter.  

2. Verify on-chain data: Cross-check any activity that is communicating with your wallet to decide whether it’s engaging in normal activity or not.  

3. Use trusted wallet simulations: Always use established and accurate wallet programs that can offer a preview of on-chain modifications.

Phishing – A Never-Ending Struggle

While Solana’s fast transaction speeds act as strengths, they have weaknesses that attackers delight in targeting. Thus, with the support of constant education and appropriate attention user’s assets remain protected within the changes of the new ecosystem.
