Police are urging residents in Pakenham and surrounding areas to be wary following reports last week of corrupt USB flash drives being left in residential letterboxes.
Members of the public are allegedly finding unmarked USB drives in their letterboxes.
Upon inserting the USB drives into their computers victims have experienced fraudulent media streaming service offers, as well as other serious issues.
Police said the USB drives are believed to be extremely harmful and community members are urged to avoid plugging them into their computers or other devices.
Pictured is an image of USB drives similar to those believed to be involved in the scam.
Anyone with information about those behind the scam is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential report at www.crimestoppersvic.com.au
