These dangerous Android apps are installed 2.5 million times each month

Kaleidoscope is an ad-fraud attack targeting Android users by exploiting legitimate applications on the Google Play Store and offering malicious duplicates through third-party app stores. Approximately 2.5 million devices are affected monthly, with 20% of incidents occurring in India, and other impacted regions include Indonesia, the Philippines, and Brazil. Users unknowingly download legitimate-looking apps while malicious versions circulate elsewhere, leading to intrusive advertisements that disrupt user experience and generate revenue for cybercriminals. Google has removed flagged titles from the Play Store and is enhancing protections, but ad resellers often fail to properly vet their inventory. The adware causes device overheating, rapid battery drain, and sluggish performance, highlighting the need for user vigilance.

Google Play Store just lost a ton of apps, but this is actually a good thing

The Google Play Store has seen a decline in available apps from 3.4 million to approximately 1.8 million since the beginning of 2024, representing a loss of nearly 47%. The "games" category lost 200,000 apps, the education sector lost around 160,700 apps, and the business category saw a reduction of 115,400 apps. This removal is part of Google's effort to combat ad fraud, particularly from "vapor apps" that misled users and generated recurring advertisements. Over 56 million downloads were affected across 180 apps. Google has implemented new policies for tracking and removing spammy applications, including expanded verification requirements, mandatory app testing, and enhanced human reviews.

Google Play Store will get more tools to protect users from scammy apps

Google has announced a plan to enhance the safety of its Play Store by implementing protective measures by 2025. Google Play Protect will target malicious applications impersonating financial apps, responding to a rise in fraudulent activities, including ad fraud. The company has already removed 180 fraudulent apps from the Play Store and will alert users about unsafe apps, especially those from outside the Google Play ecosystem. Google will extend its pilot program to additional countries facing malware-based financial threats. Users are encountering significantly more Android malware from external sources. Google aims to make it harder for malicious actors to deceive users and plans to introduce a "verified badge" for secure VPN applications, with plans to expand this to other app categories. For app developers, Google is enhancing the Play Integrity API tool and providing self-help tools for dealing with tampered apps, with features expected to roll out by May. Google is also improving support channels for developers, including expanding the Google Play Developer Help Community to additional languages.

These malicious Android apps were installed over 60 million times – here’s how to stay safe

Cybersecurity experts from Bitdefender discovered an ad fraud scheme involving over 300 Android applications that collectively had more than 60 million downloads from the Google Play Store. These apps, which appeared as utility tools like QR scanners and health apps, mainly targeted users with older Android versions (Android 13 and earlier) and first appeared in the third quarter of 2024. As of the research's completion, only 15 of the identified apps were still active, with most affected users located in Brazil, and others in the United States, Mexico, Turkey, and South Korea. The deceptive apps concealed their icons, displayed intrusive ads without user consent, and attempted to harvest sensitive information. Many of these harmful apps have been removed from the Play Store, but users with them installed remain vulnerable. Signs of compromise include lagging, excessive ads, overheating, or unexpected data usage. Users are advised to uninstall suspicious apps and to use the latest version of Android, currently Android 15.
