ZachXBT Latest Survey: How Did 'Fortnite' Esports Pros Use a Meme Scam to Steal $3 Million?
Original Author: zachxbt, On-chain Detective
Original Translator: zhouzhou, BlockBeats
Editor's Note: This article analyzes how the hacker Serpent took control of accounts belonging to McDonald's, Kabosu, and others on X and Instagram, initiated a Meme Coin scam, stole approximately $3.5 million, and used it for casino gambling. Serpent was a professional player of "Fortnite" who was dropped due to cheating. In 2022, a rug pull occurred in the NFT project DAPE, co-founded by him. In 2024, the ERROR project he launched also faced a rug pull and was ultimately banned by X.
The following is the original content (slightly reorganized for better readability):
Over the past few months, I have been tracking a series of related data breaches involving McDonald's, Usher, Kabosu's owner, Andy Ayrey, Wiz Khalifa, SPX 6900, etc., which resulted in approximately $3.5 million in theft through the release of Pump Funmeme Coin.

On August 21, 2024, McDonald's Instagram account was hacked, and a promotional post for the meme coin GRIMACE was published, after which the hacker began to engage in mischief. Over $690,000 was transferred to two wallets from this pump and dump event.

On September 3, 2024, the McDonald's attacker moved 101.5 SOL to two addresses, and after actor Dean Norris's X account was compromised by the hacker, these two addresses were deployed to and targeted SCHRADER.

On September 6, 2024, funds from a McDonald's APT (Account Takeover) were transferred to a casino deposit address.

Through timeline analysis, subsequent withdrawals shortly after the deposit can be identified.

On September 12, 2024, B2fw transferred 110 SOL to two addresses involved in a meme coin presale promoted during the Usher leak event.

Subsequently, B2fw transferred 4868 SOL to the casino deposit address ECb5v, which is directly linked to other APT events, including the Andy Ayrey and Enoshima Aquarium leaks.

On October 15, 2024, Enoshima Aquarium's X account was breached, promoting a bundled meme coin. On the same day, 84 SOL obtained from this scam was transferred to ECb5v.

On October 29, 2024, Andy Ayrey (Founder of Truth Terminal) had his X account compromised, which lasted for several days and promoted 6 meme coin scams. 3GVUs was one of the addresses involved in buying the tokens.

On October 30, 2024, 3GVUs transferred 169 SOL to Ecb5vs.

Out of the $2.178 million obtained from Andy Ayrey's ATO, $750,000 was deposited into a casino deposit address Apc3e.

0.1 SOL from the Kabosu ATO funded an address that participated in the Andy Ayrey ATO.

On October 17, 2024, the owner of Kabosu's Instagram account was hacked and promoted a meme coin scam.
That day, 191 SOL from the scam was transferred to a casino deposit address:

The APT (Account Takeover) events of Kabosu and Andy Ayrey are directly related to Wiz Khalifa's APT event.
On November 3, 2023, an attacker posted a wallet address on Wiz Khalifa's account. 29 SOL was transferred to 6kwZ7, similar to what happened in the Kabosu ATO.

WIZ's deployer funds came from Andy Ayrey's ATO. Other addresses involved in the exploit redirected all gains obtained through instant swaps to a casino deposit address 0x83ee.
0x83ee6b53a0ae76b71bed0c32721a451776dbdb3a

On October 16, 2024, 0x83ee received 0.54 ETH from the scam's deployer, while SPX 6900 was compromised on October 11, 2024.
On Solana, another scam promoted by the compromised SPX 6900 account received backing from the Ken Carson attacker.

To further demonstrate the relationship between Kabosu's owner, SPX 6900, Ken Carson, and Enoshima ATO, each meme coin's deployer provided funds to the previous deployer's address through instant swap funds, attempting to obscure the origin of the funds.

Investigate how threat actor Serpent transitioned from a professional Fortnite player to aiding in a memecoin scam initiated through leaks from 9+ accounts on X and IG to steal $3.5M and use the proceeds for online casino gambling.

Serpent (SerpentAU) is a former professional Fortnite player from Australia, who was released by the esports organization "Overtime" in June 2020 after being found cheating. He then co-founded the NFT project DAPE in March 2022, which later rug-pulled.

In March 2024, Serpent launched another project called ERROR, but the project rug-pulled, leading to his ban from platform X.
Deployer Address:
0x8233873ee35547097ccb9098adbab955d7120ee8

On October 23, 2024, the ERROR deployer moved a total of 29 ETH to two instant exchanges.
Through time analysis, it was observed that these funds were received on Solana and transferred to the same gambling deposit address.

Multiple ATO (Aggressive Transaction Outcomes) directly linked to the deposit address Ecb5vs include: McDonald's, Usher, Andy Ayrey, Dean Norris, and Enoshima Aquarium. (For detailed tracking, please refer to the beginning of the document.)

Serpent gambles monthly on Roobet, Stake, BC Game, and Shuffle with stakes of millions of dollars, often screen sharing with friends on Discord.
I obtained recordings of his gambling sessions, where he inadvertently disclosed multiple deposit and withdrawal addresses.
Discord ID: 1269557350486904945

During a screen sharing session on November 1, 2024, Serpent shared a $100K deposit and $200K withdrawal, transferred to the following address.
When plotting the transaction graph, it was discovered that this address had high exposure to addresses associated with McDonald's, Andy Ayrey, and Usher ATO.
0xb8c9c8a5756a7992df65f949b7c1423eeb435aa5

During Andy Ayrey's security breach incident, another threat actor participated in hijacking these fraudulent projects, using the alias "Dex" (from Massachusetts, USA).
After I mentioned him in my Telegram channel last week, he started to panic and fabricated a story about being extorted, claiming to have lost $700K. 
The funds currently related to these security breaches are stored in the following addresses:
0xeb60a5242c1c97eb54195ec83de43bb26813c0d1
0x2355ac2929bb7051814de3c48670fccbb515d8be
4jjWZ8RaXZBqntnhu2JFidXEQWXgfKRbJQZdTHrdaqbv
Today, following the release of the first part of my investigation, Serpent started deleting all his posts on the new X account. I suspect there are still some ATO (Attack Transaction Activity) incidents related to this that I have not been able to directly trace on-chain. Regarding one of the breached accounts, I have shared a detailed investigation report with one of the victims I am collaborating with.

In June, Bloomberg reported that despite Bitcoin falling below $60,000 last week, wiping out about $235 billion in market value within seven days, and dropping close to 50% from last year’s peak, some core businesses in the crypto industry are still expanding, mainly in stablecoins, real-world asset tokenization (RWA), payments, and infrastructure. The report also noted that overall altcoin activity has contracted significantly: altcoin market capitalization has fallen from a peak of about $431 billion in November 2021 to around $170 billion, and among the tens of millions of tokens issued in recent years, fewer than 1,700 still maintain meaningful trading activity.

Japan to Assess a Framework for Yen Stablecoins and Crypto ETFs as Asia’s Compliant Payments Narrative Heats Up
Recently, according to the original report, Japan is considering the launch of yen stablecoins and cryptocurrency ETFs. Public information remains limited at this stage, and there is still no complete policy text, regulatory draft, or clear implementation timeline, so this is better characterized as a “policy discussion” rather than formal implementation. The original wording also noted that advancing stablecoin regulation in Asia is driving XRP usage and supporting growth in the XRPL ecosystem. However, based on currently available public information, there is not enough evidence to directly establish a clear causal relationship between this round of discussion in Japan and XRP or XRPL.

ZachXBT: Humanity private key leak and abnormal surge in H token should be viewed separately
On June 9, according to related disclosures, on-chain investigator ZachXBT posted an update on Humanity’s roughly $31 million security incident, saying that after further analyzing fund flows, he currently tends to believe the project team was not involved in an “inside job” or a self-staged attack. According to him, the official explanation about the private key leak was broadly accurate, but before the token unlock, the price of H had been artificially pushed higher, and the hacker later took advantage of that market environment; therefore, the private key leak and the earlier abnormal price pumping should be regarded as two separate and independent events. This reframing has shifted the market’s understanding of the nature of the incident. Earlier discussion around Humanity had focused on whether the team directly participated in the attack or used the security incident to cover up internal operations. ZachXBT’s latest remarks shift the focus from “whether it was self-theft” to “whether there were pre-unlock market structure issues.” He also questioned whether the team may have.
