A new variant of the Konfety malware targets high-end Android devices using sophisticated evasion techniques, including distorted APK files to avoid detection. This version disguises itself as legitimate applications, imitating popular apps on the Google Play Store. It employs an 'evil twin' tactic, emphasizing the need to download software only from trusted publishers and avoiding third-party APKs. The malware can redirect users to harmful websites, install unwanted software, and generate misleading notifications. It displays ads through the CaramelAds SDK and can exfiltrate sensitive data such as installed applications and network configurations. Konfety can conceal its app icon and name, using geofencing to alter behavior based on location, and employs an encrypted DEX file to hide services. To evade analysis, it manipulates APK files to appear encrypted, causing misleading prompts during inspection, and compresses critical files with BZIP, leading to parsing failures. Users are advised to avoid sideloading apps, ensure Google Play Protect is enabled, and consider installing a reputable antivirus to enhance security.

A concerning trend in mobile security shows that malicious applications and spyware are increasingly targeting Android users. Adware, particularly the Android.HiddenAds family, remains the most prevalent threat, despite a decrease in detections. The Android.MobiDash adware trojans have increased by over 11%. The Android.FakeApp malware, which disguises itself as legitimate applications, has seen a 25% decline in activity, primarily targeting Turkish and French-speaking users. The Android.Banker variant has surged by over 70%, indicating a rise in banking trojans. A large-scale crypto theft operation involved the Android.Clipper.31 trojan embedded in a modified WhatsApp version and low-cost Android firmware, which replaces cryptocurrency wallet addresses. Spyware named Android.Spy.1292.origin targets Russian military personnel through a counterfeit mapping application. Malicious applications continue to be found on Google Play, including adware disguised as cryptocurrency news apps and fake finance applications. The open nature of Android poses ongoing cybersecurity risks, even within official app stores.

Android malware has surged by 151% since the beginning of the year, with a notable 147% increase in spyware in 2025. Spyware activity peaked in February and March, reaching nearly four times the baseline. Smishing attacks via SMS increased by 692% between April and May. Banking trojans and spyware are increasingly hidden in seemingly legitimate applications, such as fake loan services. Over 30% of Android devices run outdated software lacking security patches, exposing users to vulnerabilities. Cybercriminals are developing interconnected operations that target sensitive user data. Google Play Protect is not fully effective, and users are advised to download apps only from official sources, review app permissions, deny unnecessary notification access, keep software updated, and use trusted mobile security apps.

The ClickFix attack vector has increased by 517% since the latter half of 2024, becoming the second most exploited method for cyberattacks, following phishing. Hackers are using ClickFix to deploy various infostealing malware, including Lumma Stealer, VidarStealer, StealC, and Danabot. The ClickFix mechanism involves a counterfeit reCAPTCHA that misleads users into executing harmful Powershell commands. This method is primarily spread through phishing emails directing users to fraudulent websites. ESET’s Threat Report indicates that SnakeStealer has surpassed Agent Tesla as the most frequently detected infostealer, targeting businesses in the US and EU for credential theft. The ransomware landscape has been disrupted by internal conflicts among groups, with DragonForce launching defacement campaigns against other ransomware entities. On mobile devices, Kaleidoscope infections have caused a 160% increase in Android adware detections, and the SparkKitty malware has been found in both the Apple App Store and Google Play Store. Kaleidoscope generates revenue through intrusive ads while infecting devices with a malicious app from third-party stores.

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's AI-driven threat detection and security measures blocked approximately 2.36 million policy-violating applications from being released on the Play Store last year. In February, Google removed hundreds of malicious applications that were infecting devices with adware and malware. Over 50 times more Android malware originates from internet-sideloaded sources compared to those found on the Play Store. Google is expanding its Play Protect feature across all applications and the upcoming Android 15 will introduce live threat detection. Sophos warned about PJobRAT malware, which can steal SMS messages, contacts, and files from infected Android devices. Experts advise against sideloading apps unless their legitimacy and security are certain.
