Applying security patches in time offers better security against malware attacks. Lately, threat actors are actively scanning the internet for vulnerable WebLogic server and Salt software to launch attacks against companies. The RCE vulnerability affecting Oracle’s WebLogic server is one of many vulnerabilities that was patched in Oracle’s April 2020 Critical Patch Update. On the other hand, the vulnerabilities affecting Salt software have been exploited to hack nearly ten companies to date, including LineageOS and the Ghost blogging platform.
Meanwhile, a new variant of SLocker Android malware has been detected locking users out of their Android phones. The variant is disguised as ‘Koronavirus haqida’ app to trick users. The victims affected by the malware variant are asked to call a number in order to unlock their phones.

Android SLocker variant
A new variant of SLocker Android malware is masquerading as ‘Koronavirus haqida’ app that locks users out of their phones. Once installed, the app downloads a package named ‘com.lololo’ that locks the screen and displays a message to enter a code within 20 minutes to unlock it. The text asks the victims to contact on a given phone number to get the code.
Stealing data from air-gapped systems
In a recent study, a researcher demonstrated a new kind of malware that could be used to covertly steal highly-sensitive information from air-gapped and audio-gapped systems. This can be done by using a technique, called POWER-SUPPLaY, which leverages electromagnetic, acoustic, thermal, and optical covert channels in addition to power cables to exfiltrate data from non-networked computers.
