The attribution to cyber attacks has always been an Achilles heel for security researchers. However, in a sudden turn of events, the perpetrators behind one of the major bank hacks have been identified. A hacker group known as Silence has been found to be responsible for the attacks against three private banks in Bangladesh. These banks are Dutch Bangla Bank Limited, NCC Bank and Prime Bank.
Several new malware strains and vulnerabilities emerged in the last 24 hours. A new variant of BianLian banking trojan that includes two new modules was discovered. The modules are designed to record the screens of infected Android devices along with creating an SSH server. Researchers spotted a new Lua-based backdoor malware dubbed ‘Godlua’ which is capable of targeting both Linux and Windows users while securing its communication channels via DNS over HTTPS (DoH).
Major security vulnerabilities were also reported. This includes the discovery of critical vulnerabilities in three different virtual reality applications that allowed attackers to take control of victims’ computers. Likewise, nine flaws were detected in Lenovo servers that could compromise systems.

Top Malware Reported in the Last 24 Hours
BianLian banking trojan
Researchers spotted a new variant of BianLian banking trojan that includes two new modules designed to record the screens of infected Android devices along with creating an SSH server. The updated BianLian variant is distributed in the form of a heavily obfuscated APK that relies on generating a variety of random functions in order to hide the real functionalities of the trojan. The trojan also drops a malicious payload on the infected Android devices which enables it to check if Google Play Protect is active through the Google SafetyNet API.
A new Lua-based backdoor malware dubbed ‘Godlua’ was also identified by security researchers. Godlua is capable of targeting both Linux and Windows users while securing its communication channels via DNS over HTTPS (DoH). Two versions of the malware were detected. The first version of Godlua malware is obtained by traversing Godlua download servers and targets the Linux systems. The second version targets Windows systems and is reported to actively receive updates on a regular basis.
Sodinokibi exploits Windows bug
Sodinokibi ransomware now escalates its privileges on an infected system by exploiting a vulnerability in the Win32k component present on Windows 7 through 10 and Server editions. It exploits the CVE-2018-8453 vulnerability which Microsoft patched in October 2018. The ransomware discriminates between targets and terminates on computers with keyboard layouts specific to countries such as Russia, Ukraine, Belarus, Tajikistan, Armenia, Azerbaijan, Georgia, Kazakhstan, Kyrgyzstan, Turkmenistan, Moldova, Uzbekistan, and Syria.
Top Vulnerabilities Reported in the Last 24 Hours
Security vulnerabilities in Lenovo servers
A total of nine security vulnerabilities were detected in Lenovo servers that could highly impact systems. The vulnerabilities include use-after-free issues, command injection flaw, improper authentication, and other security issues. Out of the nine flaws, two were tagged as high-risk flaws. Lenovo has fixed six of the vulnerabilities.
Chinese attackers exploit Equation Editor flaw
Chinese threat actors updated a Rich Text Format(RTF) weaponizer to exploit a specific Microsoft Equation Editor flaw (CVE-2018-0798) in order to drop malicious payloads. This weaponizer was earlier used to exploit two remote code execution(RCE) flaws, CVE-2017-11882 and CVE-2018-0802, in Equation Editor. The threat actor groups using this tool include Conimes, KeyBoy, Emissary Panda, Rancor, and Temp.Trident.
Vulnerabilities in Virtual Reality applications
Researchers have detected several critical vulnerabilities in three different virtual reality applications that could allow attackers to take control of victims’ computers. The three impacted virtual reality applications include VRChat, Steak VR, and High Fidelity. Successful exploitation could allow the attackers to access users’ webcams, microphones, or manipulate what they see within their VR headset. Attackers could also create a VR malware that infects anyone entering the chat room.
Security flaw in iMessage
A security flaw was detected in iMessage, an instant messaging application by Apple, that could brick iPhones. The flaw was discovered by security researcher Natalie Silvanovich of Google Project Zero. According to Silvanovich, a method in an iMessage component threw an exception when it encountered a malformed message containing a text key. This eventually would brick the iPhones.
