Submission + - Mozilla suspends Firefox Send service while it addresses malware abuse (zdnet.com)
An anonymous reader writes: Mozilla has temporarily suspended the Firefox Send file-sharing service as the organization investigates reports of abuse from malware operators and while it adds a "Report abuse" button. The browser maker took down the service today after ZDNet reached out to inquire about Firefox Send's increasing prevalence in current malware operations.
Since last year, several malware operations have hosted payloads on the service. This includes ransomware gangs like REvil/Sodinokibi, financial crime crews like FIN7, the Zloader and Ursnif banking trojans operations, and government surveillance groups targeting human rights defenders. Reasons include the fact that Firefox Send doesn't have an Report Abuse mechanism, all file uploads are encrypted (useful to dodge malware scanners), and the Firefox URL is whitelisted in most orgs (useful for bypassing email filters).
