The breach hit core JavaScript libraries like chalk, strip-ansi, and color-convert—packages so foundational they’re practically digital plumbing. Together, these libraries are downloaded billions of times every single week, quietly running inside everything from web apps to developer tools. Most devs never install them directly, but they lurk deep in dependency trees. That’s why this attack is systemic.
According to multiple security reports, attackers compromised the NPM account of a well-known developer, slipped malicious code into these libraries, and shipped them straight into the global software bloodstream. The payload? A crypto-clipper—malware that swaps out wallet addresses mid-transaction, silently diverting funds to the attacker.
If you’ve ever copied a wallet address, pasted it into a field, and hit “Send,” this is your nightmare scenario. The code hijacks the destination address, and unless you manually double-check on a hardware wallet, your funds are gone.

The TLDR from security researchers, source: Observations
It’s still unclear whether the malware goes further—some researchers speculate it might also attempt to steal seed phrases directly. If true, this would elevate the hack from “clipper attack” to “full-on wallet drain.”
It’s another brutal reminder that our entire digital infrastructure rests on volunteer-maintained open-source codebases—often written by one person in their free time. Chalk isn’t glamorous, but it’s everywhere. When attackers compromise something this fundamental, the fallout ripples across the entire internet.
Crypto just happens to be the juiciest target because it’s instant money, no chargebacks, no middleman. But make no mistake: the real crisis is that the global software supply chain is held together with duct tape and trust.
Send transactions with caution until this is resolved.
