Late last year, the tech giant began blocking apps identified as helping users gain illegal access to pirated content.

At the time, an Amazon spokesperson said: “Piracy is illegal, and we’ve always worked to block it from our Appstore.

“Through an expanded program led by the Alliance for Creativity and Entertainment (ACE), a global coalition fighting digital piracy, we’ll now block apps identified as providing access to pirated content, including those downloaded from outside our Appstore.

“This builds on our ongoing efforts to support creators and protect customers, as piracy can also expose users to malware, viruses, and fraud.”

Initially, customers received notifications about any apps identified as facilitating piracy and were given the option to uninstall.

Now these apps are being blocked entirely, making them impossible to download/install.

Fire Stick users getting on-screen warning as fears grow of more blocked apps

A message has now begun appearing on select Fire TV Sticks, which has users concerned that all sideloaded apps (those from sources outside the official Appstore) have been blocked.

The message, according to AFTVnews, reads: “Unauthorized APK installation detected. Please do not install performance benchmark APKs without permission from deviceprot@amazon.com.”

AFTVnews added: “There has been a new surge of this happening over the last couple of weeks.

“The recent uptick in this issue seems to specifically be on new Fire TV Smart TVs from TCL, but it can affect any Fire TV model.”

The tech experts explain that this message is an error and was never meant for regular Fire TV Stick users.

It was designed for Amazon’s internal testers to stop them from accidentally leaking details about unreleased Fire TV devices through benchmarking apps.

So why are regular users now seeing this message? There are two reasons:

1. They bought a used Fire TV that was previously used for internal Amazon testing.
2. Their new Fire TV was mistakenly flagged as an internal testing unit due to a registration or software error.

What to do if you get “unauthorized APK installation” message

Unfortunately for users, there is no way to fix the issue yourself – even a factory reset won’t work.

If you are seeing the “unauthorized APK installation” message, AFTVnews recommends contacting Amazon customer support (be sure to have your full device serial number and the message).

The tech experts continue: “You should keep the device powered on and connected to the internet.

“Try sideloading something every few days to see if the message has gone away.”

Crackdown on ‘dodgy’ Fire Sticks intensifies

The ongoing crackdown on the use of ‘dodgy’ Fire Sticks in the UK continues to intensify.

Illegal TV Fire Sticks and/or ‘dodgy boxes’ are streaming devices that have third-party software installed in them, allowing users to watch premium content from providers such as TNT Sport, Sky, Disney+ and Netflix for free.

The use of these devices is a “serious crime”, and police forces across the UK and Ireland, as well as organisations including Crimestoppers and the Federation Against Copyright Theft (FACT), have been attempting to stamp them out.

People who access illegal TV streaming services are potentially liable to prosecution for criminal offences, including under Section 11 of the Fraud Act 2006.

FACT is continually intensifying enforcement targeting users of illegal streaming devices/services.

Thousands of individuals across the UK were contacted recently and warned to stop using illegal IPTV services immediately or risk criminal prosecution.

This action followed joint investigations with police that uncovered details of customers who had purchased access to so-called “loaded” Fire Sticks, Android, or Kodi devices.

While FACT’s latest campaign to disrupt illegal streaming networks and protect consumers from the risks associated with illicit online content targeted eight areas across the UK:

• London
• South West
• North West
• North East
• Scotland
• Wales
• Yorkshire and Humber
• West Midlands

The likes of Sky and Amazon are also working on ways to prevent the use of ‘dodgy’ Fire TV Sticks in the UK.

The dangers of using illegal streaming devices

“Illegal streaming services are increasingly operated by sophisticated criminal networks, often involved in other types of crime,” BeSteamWise explained.

Meaning those who use illegal streaming devices run the risk of “letting criminals in”, resulting in:

• Viruses and malware
• ID theft, scams, and fraud
• Inappropriate content

Around 39% of illegal streamers in the UK have suffered financial losses due to cybercrime linked to piracy, according to BeStreamWise.

The average amount stolen through illegal streaming is £1,680, while one in ten have lost more than £5,000.

What is the penalty if caught with a ‘dodgy’ Fire TV Stick?

Not only can the use of illegal streaming devices leave users open to ID theft, fraud, and viruses, but it can also result in fines and jail time.

RECOMMENDED READING:

Those caught using or selling a ‘dodgy’ fire stick/box and streaming premium content without paying are in breach of Section 11 of the Fraud Act 2006.

It says a person will be in breach if they obtain services “without any payment having been made for or in respect of them or without payment having been made in full”.

A person found guilty of this kind of offence could be fined or face a jail sentence of up to five years.
