Malicious actors continue to target CVE-2022-30190, which involves unauthenticated remote code execution affecting the Windows Support Diagnostic Tool (MSDT). This was addressed on June 14, 2022, as part of monthly Windows updates. This vulnerability is now being exploited to deploy Rozena backdoor.
The starting point to Rozena backdoor is a malicious Office document delivered via social engineering campaigns that can establish remote shell connections to attacker-controlled systems. Once that connection is established, PowerShell commands and following stage payloads, including batch files that establish persistence by Windows Registry modification and downloads a harmless Word document as a decoy.
Awareness and user education continues to be an essential effort to mitigate incidents stemming from malicious emails. Users and administrators should ensure Windows systems are kept up to date (especially the June Windows updates). Administrators should consider blocking zip email attachments or other attachments that rarely have legitimate business purposes.

Fortinet addressed multiple vulnerabilities affecting endpoint security products. This includes path traversal vulnerabilities in the management interface of FortiDeceptor that creates virtual machines to serve as honeypots for network intruders (CVE-2022-30302). Other vulnerabilities include privilege escalation via directory traversal attack in FortiClient for Windows and unprotected MySQL root account in FortiNAC.
Attempts at exploiting these vulnerabilities would require authenticated access. Furthermore, there have been no reports of exploitation in the wild up to this point. Administrators should be aware that exploitation could potentially lead to device compromise if exploits become publicly available.

In what may be the most significant data breach in human history, an attacker offers to sell the data of a billion Chinese citizens. According to Wired magazine, a management dashboard was publicly exposed, allowing attackers with “basic technical skills” to download information without a password.
Considering the massive and well-known government surveillance program imposed upon the Chinese civilians, this breach will likely have a high impact on the Chinese citizenry. Identity theft, phishing, and extortion will all be facilitated if this data gets into the hands of motivated attackers.
Securing data in the cloud is challenging. Misconfiguration of cloud services is an all-too-common source of data exposure. Applications and data storage need to be carefully planned by well-trained people and supported by rigorous change control measures. We suggest you join GreyCastle Security’s webinar on Managing Cloud Computing Cybersecurity on Thursday, July 14, to gain insight on standard cloud attack methods and security considerations.

According to sources such as Cyware and Hipaajournal.com, a February 2022 ransomware attack on “Professional Finance Company,” a debt collection firm based in Greeley, Colorado, resulted in the exposure of data belonging to 657 healthcare organizations.
Exposed data included sensitive personal information, including names, addresses, payment information, social security numbers, and patients’ birth dates. Data such as this is more than enough to launch identity theft attacks against the victims.
Security programs must address all aspects of information handling for cloud services, on-premises implementations, and third-party data exchange. GreyCastle Security recommends reviewing all contracts to address cybersecurity concerns appropriately.
