Cybersecurity Alert: SleepyDuck Trojan Hits 14,000 Downloads in Malicious Extension Scandal!
Cybersecurity researchers identified a new malicious extension, SleepyDuck, in the Open VSX registry, targeting Solidity developers. The extension cunningly updates its command and control address using an Ethereum contract, giving hackers more control than a toddler with a remote. This discovery adds another quack to the malware pond.

Hot Take:
Just when you thought it was safe to go back into the code editor, along comes SleepyDuck, quacking its way into your system like it’s nobody’s business. Who knew that a seemingly innocent extension could pack more drama than a daytime soap opera? The real kicker? It’s smart enough to use Ethereum contracts like some kind of digital MacGyver, evading capture and causing developers all sorts of headaches. So, if you’re a Solidity developer, you might want to check your extensions before they check you!
Key Points:
– SleepyDuck is the latest malicious extension in the Open VSX registry, targeting Solidity developers.
– The extension transforms from a benign library to a Trojan horse after 14,000 downloads.
– It employs Ethereum contracts for sandbox evasion and updating its command and control address.
– Can execute commands, gather system data, and adapt if its server is taken down.
– Developers are advised to download extensions only from trusted sources.
