Top Malware Reported in the Last 24 Hours

Top Vulnerabilities Reported in the Last 24 Hours

Vulnerable Android phones
A newly discovered security flaw in Android phones from Samsung, Huawei, LG, and Sony can leave users open to advanced phishing attacks. This could enable attackers to steal users’ personal information. The flaw arises because the phones use over-the-air (OTA) provisioning. The attacker can make use of the OTA method to disguise their malicious SMS as an ‘update network settings’ text from the mobile network provider.

Google fixes 50 vulnerabilities
As a part of the September 2019 Patches, Google has released a new set of security patches that address nearly 50 vulnerabilities on the Android platform. The flaws impact Android versions 8.0, 8.1,9 and 10. 11 of these vulnerabilities are rated ‘High’ severity. Five of these impact Framework, while the remaining five are found in the System component of Android. In another incident, researchers have warned about a high-severity zero-day vulnerability in Google’s Android operating system. If exploited, the bugs could give a local attacker escalated privileges on a target’s device.

Vulnerable EZAutomation software
Security researchers have discovered vulnerabilities in two pieces of software made by EZAutomation, the U.S.-based industrial automation solutions provider. The potentially serious bugs - CVE-2019-13518 and CVE-2019-13522 - can be exploited for remote code execution. The vulnerabilities have been patched by EZAutomation in EZPLC Editor 1.9.0 and EZTouch Editor 2.2.0. The vendor has also advised users to only open project files from trusted sources.

Top Scams Reported in the Last 24 Hours

Scammers mimic SCA security check
Scammers are leveraging the new Strong Customer Authentication (SCA) regulation to trick users into sharing their personal details and banking credentials. They are mimicking the SCA-related messages and sending them through emails that appear to come from legitimate banks such as Santander, Royal Bank of Scotland (RBS) and HSBC. Each of these scam emails includes links to sites that are meant to capture personal details of users. The attacks are aimed at users in Europe. Users should be cautious about such emails and cross-check the links before providing their details.
