ZachXBT Warns of New EVM Chains Security Risk: Cause Still Unknown
Share
Key Takeaways
The wallet-draining activity appears cross-chain and automated, suggesting a shared EVM exploit rather than isolated user error.
The root cause remains unconfirmed, with permission abuse, malicious signatures, and supply-chain compromise all still under investigation.
The suspicious address 0xAc2e5153170278e24667a580baEa056ad8Bf9bFB acts as a central aggregation point, indicating coordinated draining behavior.
Until more details emerge, strict wallet hygiene and defensive security practices are the most effective protection against ongoing EVM-based threats.
Blockchain investigator ZachXBT has warned the crypto community about a growing and unexplained wallet-draining threat affecting multiple EVM-compatible blockchains.
The activity, which spans several networks that rely on the Ethereum Virtual Machine (EVM), has already resulted in unauthorized asset losses with funds siphoned in small amounts, typically under $2,000 per wallet, across numerous addresses, raising concerns about a potentially systemic vulnerability.
. @zachxbt : It appears hundreds of wallets are currently being drained on various EVM chains for small amounts (<$2k total per victim) with a root cause not yet unidentified.
So far ~$107K has been drained from them with the theft total still increasing.
So far $107K has been drained from them with the theft total still increasing. However, the exact cause of the attacks remains unknown, but early analysis suggests that the exploit may involve permission abuses, malicious signature techniques, or a broader supply-chain compromise affecting wallet infrastructure.
On-Chain Signals Indicate a Coordinated EVM-Based Exploit
On-chain data indicates a patterned and automated attack, rather than isolated user mistakes. Victims report assets being transferred out without intentional authorization, often shortly after routine interactions such as signing messages or interacting with decentralized applications.

Key Observations
Wallet drains observed across multiple EVM-compatible networks
Funds consolidated into a single aggregation address
No confirmed vulnerability in a specific DeFi protocol
Losses often small per wallet, consistent with stealth-draining tactics
This cross-chain behavior suggests the exploit targets shared EVM wallet mechanics, rather than a flaw in any single blockchain.
Why EVM Chains Are Particularly Exposed to Crypto Hacks
EVM wallets are cryptocurrency wallets designed to store, send, receive, and manage digital assets on EVM-compatible blockchains – networks that run on the EVM.
EVM-compatible chains share:
Identical transaction and signature standards
Common wallet software and browser extensions
Standardized permission models such as ERC-20 approvals and permit() signatures
Because of this shared architecture, a single exploit vector can scale rapidly across the entire EVM ecosystem, impacting users on multiple networks simultaneously.
Possible Attack Vectors (Still Under Investigation)
The following scenarios remain theoretical and have not been officially confirmed.
Permission Abuse and Token Allowance Exploits
Users may have unknowingly approved malicious smart contracts, granting them unlimited access to tokens. Once permissions are in place, attackers can drain assets using transferFrom() without further interaction.
Typical Indicators
ERC-20 tokens drained while native coins remain untouched
Revoking approvals prevents further losses
Malicious Signature Exploits
Some wallets allow users to sign off-chain messages that can later be used to authorize on-chain transfers. Deceptive signing prompts may trick users into approving asset movement without realizing it.
Typical Indicators
User recalls signing a message but not approving a transfer
Drain occurs shortly after interaction
Supply Chain Vulnerabilities
The most severe possibility is a compromise at the wallet or extension level. In such cases, attackers may gain access to private keys or seed phrases, enabling complete wallet takeover across all EVM chains.
Typical Indicators
Native coins and tokens drained together
Wallet continues to be drained even after revoking approvals
The address 0xAc2e5153170278e24667a580baEa056ad8Bf9bFB appears to function as a central collection wallet. Its activity profile shows:
Inflows from numerous unrelated wallets
Repetitive transaction behavior consistent with scripted drains
Consolidation patterns commonly associated with wallet-drainer operations
Tracking this address is crucial for understanding the full scope of the attack and identifying related infrastructure.
How to Protect Your Wallet From EVM Chain Draining Attacks
Until the root cause of the EVM wallet draining activity is fully identified, users must take immediate precautionary security measures to reduce potential losses.
Immediate Risk Mitigation Steps
Transfer funds to a new wallet created with a fresh seed phrase on a clean device
Revoke all token approvals on affected wallets across all EVM-compatible chains
Avoid signing messages or transactions unless absolutely necessary, especially blind signature requests
Audit browser extensions and wallet software, removing any unknown or unused tools
Remain cautious of follow-up scams, including fake reimbursement forms, support messages, or “security alerts”
Broader Implications for Crypto Security
This incident underscores a persistent challenge in the crypto ecosystem: wallet-level security remains a critical attack surface.
Whether the final explanation involves permission abuse, signature manipulation, or a supply-chain breach, the impact highlights the systemic risks posed by shared EVM infrastructure.
What is the EVM chains wallet draining risk flagged by ZachXBT?
The EVM chains risk refers to unauthorized wallet drains across multiple EVM-compatible blockchains, highlighted by blockchain investigator ZachXBT. The attacks appear coordinated, automated, and cross-chain, with funds flowing to a single suspicious address.
Is the root cause of the EVM wallet drains confirmed?
No. The exact cause is still unknown. Current theories include token permission abuse, malicious signature exploits, or a supply-chain vulnerability affecting wallet software or browser extensions.
Why are multiple EVM chains affected at the same time?
EVM-compatible blockchains share the same transaction logic, wallet infrastructure, and permission standards. This means a single exploit vector can be reused across different networks, amplifying the impact.
What should users do if they suspect their wallet is at risk?
Users should move funds to a new wallet immediately, revoke all token approvals, avoid signing messages, audit wallet extensions, and remain alert for scam follow-ups pretending to offer compensation or support.
