Twice in five days, developers of Chrome browser extensions have lost control of their code after unidentified attackers compromised the Google Chrome Web Store accounts used to issue updates.

The most recent case happened Wednesday to Chris Pederick, creator of the Web Developer extension. Last Friday, developers of Copy Fish, a browser extension that performs optical character recognition, also had their account hijacked.
