Safemoon - REKT
Not so safe after all.
Yesterday, Safemoon lost $8.9M worth of ‘locked LP’ thanks to a bug introduced in the project’s latest upgrade.
The attack, which drained the SFM/BNB pool, was announced by the project and its CEO, John Karony, with replies disabled on both tweets.
A few hours after the attack, the hacker sent a message to the Safemoon: Deployer address, claiming to be MEV bot operator willing to return the funds:
Hey relax, we are accidently frontrun an attack against you, we would like to return the fund, setup secure communication channel , lets talk
However, past on-chain activity suggests they are no white knight after all…
Even if the team has dodged a bullet this time…
…can they be trusted after such a basic error?

Just over six hours before the attack, the Safemoon: Deployer address upgraded the token contract to a new implementation. In doing so, the team introduced a vulnerability leading to an astonishingly simple exploit.
The new code left the burn() function publicly callable, allowing anyone to burn SFM tokens from any address.
This allowed the attacker to burn large quantities of SFM held inside the SFM:BNB liquidity pool, vastly inflating the price of SFM tokens in the pool.
Then, by selling (previously acquired) SFM tokens into the skewed pool, the attacker was able to drain it of BNB liquidity, for a profit of 28k BNB, or $8.9M.

The hacker claims to have frontrunned attack and has reached out to Safemoon to negotiate the return of funds, the majority of which have since been transferred to 0x237D where they remain at the time of writing.
Since its launch two years ago, Safemoon has been beset by scandal.
Initially labelled as a pump and dump scheme, Safemoon shillfluencers were later slapped with a class action suit, before Coffeezilla published a series of detailed investigations into what went on behind the scenes.
The favourite of tiktok investors during the peak of Spring 2021’s BSC hype, Safemoon claimed it was un-ruggable due to locked liquidity, which was topped-up with every transfer of tokens. However, the transfer fees were also criticised as ponzinomics as bagholders were disincentivised to sell.
At the peak of shitcoin szn, we wrote:
the shitcoins show no sign of stopping
The markets have cooled down significantly since then, and it seems hardly believable that some of these projects have managed to survive this far….
Given the vulnerability was introduced by the project’s deployer address, Peckshield (perhaps charitably, or perhaps via Hanlon’s Razor) suggested that admin keys may have been leaked or phished.
Regardless of whether the funds are in the hands of a blackhat hacker or whitehat MEV frontrunner, the lack of trust in Safemoon from the wider crypto community suggests they’ll unlikely be safe, even with the team…
Whether a botched rug attempt, or sheer incompetence, this episode is not a good look for a project that was never very highly regarded.
Despite all the bad press, any remaining soldiers in the SFM army appear to still believe, or are suffering from a bagholder’s case of Stockholm Syndrome.
Perhaps if they haven’t been put off by now, they never will be.
And even if this turns out to be a lucky escape for Safemoon, errors like this don’t bode well for the project’s future.
How much longer can Safemoon last?
