SafeMoon is a human-focused technology and innovation business expanding blockchain technologies to build blockchain, commerce, metaverse, and NFT products for good. SafeMoon has faced criticism in the past, initially labeled as a pump and dump scheme, and later shillfluencers were slapped with a class action suit. The project claims to be un-ruggable due to locked liquidity, but the transfer fees were criticized as ponzinomics. SafeMoon recently suffered an attack that drained the SFM/BNB pool, causing the project to lose $8.9M worth of 'locked LP.' The hacker claims to have front-run the attack and has reached out to SafeMoon to negotiate the return of funds. However, the past on-chain activity suggests they may not be trustworthy.

About Safemoon

Safemoon describes themselves as "[a] human-focused technology and innovation business expanding blockchain technologies for a brighter tomorrow."

"A human-focused technology and innovation business expanding blockchain technologies for a brighter tomorrow."

"Deeply connected to and driven by our award winning community (The SafeMoon Army), we are innovating for good. Building blockchain, commerce, metaverse and NFT products to derive new kinds of value from crypto technology and to apply it to increasingly better use."

"We are now addressing the second part of our mission – the expansion and channeling of our technology to propel new innovations for good, and a Venture Philanthropy model to advance those innovations to every part of the world."

The Reality

"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."

"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 sections is included if a case involved deception or information that was unknown at the time. Examples include:

• When the service was actually started (if different than the "official story").
• Who actually ran a service and their own personal history.
• How the service was structured behind the scenes. (For example, there was no "trading bot".)
• Details of what audits reported and how vulnerabilities were missed during auditing.

What Happened

The specific events of the loss and how it came about. What actually happened to cause the loss and some of the events leading up to it.

Key Event Timeline - Safemoon Vulnerable Deployer Exploited

Date	Event	Description
March 28th, 2023 1:26:27 PM MDT	Theft Transaction	The transaction happens to remove the liquidity from Safemoon.
March 28th, 2023 3:17:00 PM MDT	Attack Announced on Twitter	The exploit is announced on Twitter. Responses to the Tweet are disabled.
March 29th, 2023 11:31:00 AM MDT	RektHQ Article	RektHQ publishes an article on the situation. Safemoon, a two-year-old cryptocurrency beset by scandal, lost $8.9m worth of locked LP tokens thanks to a bug introduced in its latest upgrade. The project's CEO, John Karony, announced the loss, but replies were disabled on both tweets. The hacker responsible claimed to be a white knight willing to return the funds, but past on-chain activity suggested otherwise. The vulnerability was introduced by the project's deployer address, and Peckshield suggested admin keys may have been leaked or phished. This episode is not a good look for a project that was never very highly regarded, and the lack of trust from the wider crypto community suggests the project may not be safe, even with the team.
April 20th, 2023 6:39:00 AM MDT	Distribution of Retrieved Liquidity	SafeMoon has announced on Twitter that they will begin distributing the recovered liquidity.

Technical Details

This section includes specific detailed technical analysis of any security breaches which happened. What specific software vulnerabilities contributed to the problem and how were they exploited?

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."

"Safemoon lost $8.9M worth of ‘locked LP’ thanks to a bug introduced in the project’s latest upgrade."

Total Amount Lost

The total amount lost has been estimated at $8,900,000 USD.

How much was lost and how was it calculated? If there are conflicting reports, which are accurate and where does the discrepancy lie?

Immediate Reactions

How did the various parties involved (firm, platform, management, and/or affected individual(s)) deal with the events? Were services shut down? Were announcements made? Were groups formed?

Attack Announcement on Twitter

The SafeMoon team initially posted on Twitter to announce the exploit.

To the @SAFEMOON community: We want to inform you that our LP has been compromised.

We are taking swift action in an attempt to resolve the issue as soon as possible. Follow here for updates.

Thank you for your support as we work to address this situation.

"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?"

"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."

"Whether a botched rug attempt, or sheer incompetence, this episode is not a good look for a project that was never very highly regarded."
