Diavol Ransomware – DFIR Report
Industry: N/A | Level: Operational | Source: DFIR-Report
Intrusion analysis from The DFIR Report identified a BazarLoader infection leading to the deployment of Diavol Ransomware. The threat actor associated with Diavol ransomware is suspected to be Wizard Spider. The intrusion spanned over the course of three days in which the threat actors initial access was obtained from BazarLoader, delivered through a phishing email containing a malicious OneDrive link and following the infection, internal reconnaissance activity was initiated along with the execution of a batch script obtaining credentials located in the registry hives. Following an 18 hour break in activity, additional reconnaissance activity was initiated along with usage of the Rubeus tool, lateral movement with RDP and AnyDesk, with data exfiltration using FileZilla. Lastly, along with ransomware deployment a batch script was executed removing volume shadow compiles and stopping services.

Purple Fox Rootkit
Industry: N/A | Level: Tactical | Source: Minerva-Labs
Research from Minerva reports MalwareHunterTeam, identified a malicious Telegram installer compiled in AutoIt, named “Telegram Desktop.exe.” Resulting in infection with the Purple Fox rootkit. The telegram installer attempts to evade detection utilizing small files with the first batch dropped from the initial “Telegram Desktop.exe” executable then copies specific files to the ProgramData folder, launching an executable and deleting the recently downloaded files. Following registry modifications, additional malicious files are downloaded initiating actions to run a new driver service, bypass UAC and stop AV. The final stages of the attack exfiltrate any collected information for AV products to the C2 server and download the purple fox rootkit.
BlackTech – “Flagpro”
Industry: N/A | Level: Operational | Source: NTTSecurity
Threat Actor Group – “BlackTech” has been observed by NTT Security utilizing a new malware called “Flagpro,” actively targeting Japanese companies. The malware is used in the initial stages of the attack, dropped through spear-phishing emails in a zip attachment containing a malicious Excel document with a macro. Following macro execution, the Flagpro exe is dropped into the startup directly where it executes on the next system launch. The malware communicates with the C2 server through base64 encoded traffic, with additional functions including the ability to download additional tools, execute OS commands and collect and send Windows authentication information. If the attacker identifies the compromised Flagpro host to be compatible, they’ll proceed in downloading the second stage malware.

ONUS Compromised from Log4Shell
Industry: Technology | Level: Tactical | Source: Cystack
Compromise of ONUS, a cryptocurrency platform in Vietnam was reported by CyStack as the company’s payment software from “Cyclos” was vulnerable to CVE-2021-44228/Log4Shell. Insecure misconfigurations with the company’s AWS S3 buckets escalated the attack. Details of the attack involve using Log4Shell payloads to establish a malicious connection, read file “cyclos.properties” containing AWS credentials led attackers to capitalize on the ONUS misconfigurations of granting “AmazonS3FullAccess permission to the access key which allowed attackers to compromise and easily delete all of the S3 buckets. Also on these servers, ONUS had a script to periodically back up the database to S3 which contained the database hostname and username/password as well as backup SQL files. As a consequence, the attackers could access the ONUS database to get user information.” They also downloaded a backdoor on the server disguised as the Linux operating system’s kworker service that tunneled a connection to the attacker’s C2 server using SSH. The impact of the attack involves the compromise of 2 million ONUS, information that includes EKYC and personal data, and password hashes being leaked.
Industry: Education | Level: Operational | Source: CrowdStrike
Observation of the Log4Shell vulnerability from CrowdStrike’s OverWatch team identified an attempted exploit by “Aquatic Panda” against an unnamed academic institution. It started from reviewing suspicious activity from a Tomcat process running under a vulnerable VMware Horizon instance. A combination of a suspicious activity involved the threat actor running multiple connectivity checks through DNS lookups for a specific subdomain and attempting to execute curl and wget commands to retrieve tools that were also peculiar as the execution of Linux commands were on a Windows host for the Apache Tomcat service. As the affected institution worked towards mitigating the attack, OverWatch researchers continued to track the attack identifying reconnaissance activity for system privileges, downloading additional scripts through a PowerShell Base64-encoded command dropping three files with VBS file extensions and when decoded with “cscript.exe” were identified as an EXE, DLL and DAT file. Attempts to harvest credentials were found when to dump LSASS memory and using WinRAR to compress the memory dump for exfiltration. Eventually, the victim organization was able to patch the vulnerable application and thus stopped any further activity from Aquatic Panda.
Conti & Log4Shell from AdvIntel
Industry: N/A | Level: Tactical | Source: AdvIntel
Continued vigilance on the threat landscape due to Log4Shell, has identified the Conti ransomware group showing signs of interest. A report from AdvIntel, detailed Conti had been deprived of new viable attack vectors since November, but had been searching for new methods. It wasn’t until the fallout of Log4Shell the ransomware group finally found what they’d been looking for. Multiple Conti members have been identified initiating scanning activity for the exploit. A recent quote from AdvIntel confirmed, “the criminals pursued targeting specific vulnerable Log4J2 VMware vCenter for lateral movement directly from the compromised network resulting in vCenter access affecting US and European victim networks from the pre-existent Cobalt Strike sessions.”
