Unpatched systems are easy prey for malicious actors to launch sophisticated cyberespionage campaigns. One such vulnerability is the Windows SMBGhost flaw. Despite the release of the patch, researchers have found that over 100,000 Windows systems are still vulnerable to the critical remote code execution flaw. Furthermore, threat actors have begun scanning the internet for vulnerable Oracle WebLogic servers. The flaw in question can cause complete takeover of systems.
There has also been quite a buzz about ransomware threats in the last 24 hours. While it is speculated that the Maze ransomware is about to close its operation, in another development, it has been uncovered threat actors are using Buer Loader malware to deliver the Ryuk ransomware.

Top Malware Reported in the Last 24 Hours
Buer Loader delivers Ryuk
Researchers have uncovered that Ryuk ransomware operators are heavily relying on Buer Loader malware, instead of Emotet and TrickBot, to deliver the ransomware. Buer is a malware-as-a-service tool that enables threat actors to establish a digital foothold within a network. In a campaign observed in September, the loader was found hidden within a malicious document that ultimately caused the delivery of the ransomware.
Emotet’s activity spikes
Since August 1, researchers have observed a spike in Emotet activity, roughly 1,800 detections in one day. The latest one was spotted on October 19, wherein victims were tricked with a fake update notification for Microsoft Word. In another incident, Emotet has been found using parked domains that redirect to Comcast and McAfee brands to expand its malicious campaign.
Maze ransomware likely to shut down
Speculations are that Maze ransomware operators will soon be shutting down its operations. As a part of the shut down process, threat actors have stopped encrypting new victims in September 2020 and are trying to extort the remaining victims. Furthermore, they have started cleaning up their data leak site, with just two victims’ data left to be removed.
Top Vulnerabilities Reported in the Last 24 Hours
Unpatched Windows systems
Despite the release of the patch for the SMBGhost vulnerability (CVE-2020-0796), it has been found that more than 100,000 Windows systems are still vulnerable to the flaw. Described as a remote code execution flaw, it affects Windows 10 and Windows 2019. It scores a rating of 10/10 on the CVSS scale.
QNAP has listed two vulnerabilities affecting QTS in its latest advisory. Tracked as CVE-2020-2490 and CVE-2020-2492, the two flaws are classified as command injection vulnerabilities. It is unclear as to how an attacker could exploit the vulnerabilities. The flaw does not affect the QTS system to at least version QTS 184.108.40.2061 build 20200907.
Vulnerable WebLogic server
Threat actors have started hunting Oracle WebLogic servers vulnerable to CVE-2020-14882. The flaw, that can be exploited via a simple HTTP GET request, can allow attackers to take control of systems.
