Chrome Extensions: Are you getting more than you bargained for?

### Executive Summary Symantec researchers identified four Chrome Web Store extensions (Good Tab, Children Protection, DPS Websafe, Stock Informer) that exhibit malicious or vulnerable behaviors—undisclosed clipboard access to remote HTTP domains, cookie harvesting and DGA-backed C2 with remote code execution, search hijacking and user tracking, and an exploitable XSS—affecting a combined user base in excess of 100,000; the report includes technical snippets, IOCs (extension IDs and domains), and remediation advice to uninstall the extensions and block related infrastructure.
