Malicious extensions, involved in cookie-stuffing and ad fraud, continue to breed day by day. Researchers have detected a total of 295 malicious extensions being used to insert unwanted ads inside Google and Bing search results. These extensions pose as ad-blockers, weather forecast widgets, and screenshot capturing utilities to trick users.

Meanwhile, WastedLocker ransomware operators have now gone the extra mile to avoid detection by security software. The malware has now been found abusing a Windows memory management feature as part of its anti-analysis techniques.

In other developments, Google has released patches for over 50 vulnerabilities in this month’s security updates. Nearly 40 of these flaws affect the AMLogic, Kernel, MediaTek, and Qualcomm components of Android.
