Google Play full of Trojans

Cybersecurity experts from SecneurX have recently compiled a long list of Google Play apps infected with dangerous Trojans, including:

  • Color Paint & Draw Master – Harly Trojan
  • Real Photo Editor - Joker Trojan
  • Coloring Painting - Joker Trojan
  • Happy Voice Changer - Harly trojan
  • Emoji Live Wallpaper - Joker trojan
  • Screen Mirroring Cast - Joker Trojan
  • Advanced Cast Screen - Joker Trojan

What can the Joker and Harly Trojans do?

A trend is emerging from the above reports. Most often, mobile applications with Joker and Harly Trojans impersonate relatively simple applications. Some of them are games, others are used for simple entertainment or personalization of the smartphone by changing the wallpaper or screensaver. Screen mirroring and screen casting applications are also popular. Viruses are designed to steal data, e.g. taking over our contacts or reading e-mails, text messages or conversations on messengers. Malware can also enable premium services and charge us a high phone bill.

Price and tax changes in App Store announced

Apple announces changes to pricing and tax rules for several countries. On February 13, 2023 prices of apps and in-app purchases excluding auto-renewable subscriptions will be adjusted. In some countries prices will remain the same but developer proceeds will be adjusted to accommodate tax changes.

On February 13, 2023, prices of apps and in-app purchases (excluding auto-renewable subscriptions) on the App Store will increase in Colombia, Egypt, Hungary, Nigeria, Norway, South Africa, and the United Kingdom. Prices in Uzbekistan will decrease to reflect a reduction of the value-added tax rate from 15% to 12%. Your proceeds will be adjusted accordingly and will be calculated based on the tax-exclusive price.

While prices on the App Store in Ireland, Luxembourg, Singapore, and Zimbabwe won't change, your proceeds will be adjusted to reflect the following tax changes:

  • Ireland: Reduction of value-added tax rate on electronic newspapers and periodicals from 9% to 0%
  • Luxembourg: Reduction of value-added tax rate from 17% to 16%
  • Singapore: Increase of goods and services tax rate from 7% to 8%
  • Zimbabwe: Increase of value-added tax rate from 14.5% to 15%

Additionally, by the end of January proceeds will increase for local developers selling in Cambodia, Kyrgyzstan, Indonesia, Singapore, South Korea, Tajikistan, Thailand, and Uzbekistan.
