Is SL Sender safe?
SL Sender bundles an affiliate SDK that watches every site you visit and opens background tabs to inject affiliate cookies when shopping.
SL Sender is a WhatsApp Web bulk-messaging tool, but it also ships the ImpactHero affiliate SDK, which registers an <all_urls> content script and a tab listener that checks every hostname you browse against a merchant list fetched hourly from ext.impacthero.co. On e-commerce and checkout pages it silently opens a background tab to impacthero.co to drop the affiliate's tracking cookie, then closes it. Separately, its WhatsApp automation fetches all of its DOM selectors and analytics config at runtime from an AWS Lambda URL with no integrity check, letting the operator remotely change which WhatsApp elements (contacts, messages, compose box) the extension reads and writes.
