Zero-day Vulnerabilities in SonicWall Email Security Actively Exploited
(published: April 21, 2021)
US cybersecurity company SonicWall said fixes have been published to resolve three critical issues in its email security solution that are being actively exploited in the wild. The vulnerabilities are tracked as CVE-2021-20021, CVE-2021-20022, and CVE-2021-20023, impacting SonicWall ES/Hosted Email Security (HES) versions 10.0.1 and above.
Analyst Comment: The patches for these vulnerabilities have been issued and should be applied as soon as possible to avoid potential malicious behaviour. SonicWall’s security notice can be found here https://www.sonicwall.com/support/product-notification/security-notice-sonicwall-email-security-zero-day-vulnerabilities/210416112932360/. It is important that your company has patch-maintenance policies in place. Once a vulnerability has been publicly reported,, threat actors will likely attempt to incorporate the exploitation of the vulnerability into their malicious operations. Patches should be reviewed and applied as soon as possible to prevent potential malicious activity.

Massive Qlocker Ransomware Attack Uses 7zip to Encrypt QNAP Devices
(published: April 21, 2021)
The ransomware is called Qlocker and began targeting QNAP devices on April 19th, 2021. All victims are told to pay 0.01 Bitcoins, which is approximately $557.74, to get a password for their archived files. While the files are being locked, the Resource Monitor will display numerous '7z' processes which are the 7zip command-line executable.
Analyst Comment: Attackers are using legitimate tools like 7zip to evade detections by traditional antiviruses. EDR solutions can help tracking suspicious command line arguments and process creations to potentially detect such attacks. Customers should use backup solutions to be able recover encrypted files.

Hypervisor Jackpotting: CARBON SPIDER and SPRITE SPIDER Target ESXi Servers With Ransomware to Maximize Impact
(published: February 26, 2021)
Recent reporting indicates that two prolific cybercrime threat groups, CARBON SPIDER and SPRITE SPIDER, have begun targeting ESXi, a hypervisor developed by VMWare to run and manage virtual machines. SPRITE SPIDER uses PyXie's LaZagne module to recover vCenter credentials stored in web browsers and runs Mimikatz to steal credentials from host memory. After authenticating to vCenter, SPRITE SPIDER enables ssh to permit persistent access to ESXi devices. In some cases, they also change the root account password or the host’s ssh keys. Before deploying Defray 777, SPRITE SPIDER’s ransomware of choice, they terminate running VMs to allow the ransomware to encrypt files associated with those VMs. CARBON SPIDER has traditionally targeted companies operating POS devices, with initial access being gained using low-volume phishing campaigns against this sector. But throughout 2020 they were observed shifting focus to “Big Game Hunting” with the introduction of the Darkside Ransomware. CARBON SPIDER gains access to ESXi servers using valid credentials and reportedly also logs in over ssh using the Plink utility to drop the Darkside
Recommendation: Both CARBON SPIDER and SPRITE SPIDER likely intend to use ransomware targeting ESXi to inflict greater harm – and hopefully realize larger profits – than traditional ransomware operations against Windows systems. Should these campaigns continue and prove to be profitable, we would expect more threat actors to imitate these activities.
