A harmless-looking app on Google Play may have a malicious twin elsewhere. A new Konfety variant uses the same package name as a legitimate app but hides the real payload in a lookalike version distributed through third-party stores. It employs obfuscation tactics to evade detection, while leveraging the CaramelAds SDK. Some malware no longer travels through links or attachments, it hides in plain text. Researchers have spotted attackers embedding payloads in DNS records, allowing malware to slip past traditional security tools. By encoding binaries as hex and retrieving them during DNS resolution, this technique avoids common detection points and delivers disruptive code without a visible trace. One sandbox escape makes five. Google patched a high-severity Chrome flaw that lets attackers break out of the browser’s sandbox using crafted HTML and unvalidated GPU commands.
