Safe Wallet Heist: Hacker Drains Over $2 Million in Address Poisoning Attack

In a recent cybersecurity breach, a malicious actor successfully stole over $2 million from Safe Wallet users within the past week, employing a tactic known as address poisoning theft. The attack has brought the total count of victims to 21, signalling a concerning trend in the security vulnerabilities of cryptocurrency wallets.

Blockchain security firms have diligently tracked the suspected activities behind various transactions that resulted in the loss of $2 million from Safe Wallet. The attack, executed through address poisoning theft, involves the creation of an almost identical wallet address to deceive users. 

The malicious actor then poisons the transaction history by regularly sending funds of similar amounts to the fraudulent address, leading victims to send funds to the wrong destination mistakenly.

On December 3, the cryptocurrency scam detection platform Scam Sniffer reported on social media that approximately 10 Safe Wallets fell victim to the address poisoning attacks, resulting in a total loss of $2.05 million within the past week. 

Disturbingly, the same attacker had drained $5 million from 21 users over the last four months, indicating a sustained and evolving threat.

Address Poisoning Tactics

Address poisoning is a longstanding tactic employed by cybercriminals to manipulate users into sending assets to incorrect wallets. 

The attacker strategically poisons the transaction history by creating an address with similar start and end characters to the legitimate one, increasing the likelihood of users replicating the fraudulent address and unwittingly transferring funds.

The Florence Finance Connection

In a related incident, Scam Sniffer reported a case involving Florence Finance, where a bad actor made off with $1.5 million in assets through address poisoning. The attacker utilized a contaminated address generated by create2 before converting it to DAI to prevent asset freezes. 

The incident underscores the attackers’ sophistication and ability to exploit weaknesses in the cryptocurrency ecosystem.

Given the surge in cryptocurrency scams in recent years, cryptocurrency platforms and users are urged to exercise heightened caution. Platforms can implement reminders for users with each new wallet transfer, while users are advised to rely on additional verification methods beyond transaction history. 

The incident emphasizes the need for continuous monitoring, added security checks, and user education to mitigate the risks associated with such attacks.

The Safe Wallet heist, with its $2 million loss through address poisoning theft, underscores the evolving tactics employed by malicious actors in the cryptocurrency space. 

The importance of robust security measures and user vigilance cannot be overstated as the industry grapples with increasing regulatory scrutiny and a surge in cyber threats.
