The ransomware's authors inadvertently left the decryption keys, which were completely unencrypted, in the malware registry, allowing victims to recover their data without paying a ransom.
Cybercriminals have been using open Android Debug Bridge (ADB) ports to distribute a potential Satori malware variant to Android devices. The first wake of the attacks came from the US and China, while the second wave of attacks came from Korea. Security researchers also discovered that over 48,000 IoT devices are vulnerable to ADB exploitations.
Red Alert 2.0 malware
A new campaign has been discovered delivering the Red Alert 2.0 malware. The malware is capable of gaining device administrative privileges and can also lock screen, remove passwords and more. The banking malware surreptitiously works in the background while targeting a list of banks.
Multiple vulnerabilities have been discovered in Sony's IPELA E Series Network Cameras. The first is a command injection flaw while the second is a stack buffer overflow bug.

A bug has been discovered in the Bluetooth firmware or OS software drivers. The flaw allows attackers to replace the public keys, used during devices' pairing, by injecting invalid keys. The flaw could allow attackers the ability to intercept and decrypt and/or forge and inject device messages.
Denial of Service flaws
The Apache Tomcat server contains several vulnerabilities that could allow attackers to cause a denial of service (DoS) conditions. One of the vulnerabilities is an information disclosure issue while under the other flaw the hostname verification when using TLS with the WebSocket client was missing.
Cybercriminals targeted Oracle WebLogic servers by taking advantage of vulnerable systems that have not been patched for a critical flaw. The bug allows attackers to gain control of the entire server without having access to the server's password. Patches for this issue are available. Users are advised to update their servers immediately to stay safe from such attacks.
US power networks attacked
In 2017, Russian hackers targeted US electric networks.
