FedEx has not validated the authenticity of any email address.

The two main red flags in this email are: the unfamiliar email address in the ‘To’ field, and the fact that the embedded link doesn’t point to the official FedEx website, but an unrelated third-party site.

Should a user make the mistake of following the link, a file by the name of will be downloaded onto their PC. Contrary to what the name suggests, doesn’t contain the FedEx shipment history (which is usually available online), but malware that Sophos detects as Troj/Invo-Zip.

Troj/Invo-Zip is a Trojan Horse known for dropping additional malware on infected systems and is typically spread via spam messages like the one shared here. Only Windows systems are affected by this threat, and 17/49 antivirus vendors are capable of detecting Troj/Invo-Zip, including AVG, ESET NOD32, and TrendMicro.

Hopefully users that click the link in this spam attack are protected by one of those antivirus solutions.
