The Cybersecurity and Infrastructure Security Agency (CISA) recently published an advisory regarding the exploitation of CVE-2022-47966, a remote code execution vulnerability that affects multiple on-premises Zoho ManageEngine products. Note that evidence of exploitation in the wild was first observed in January 2023.
Exploitation has been observed to gain unauthorized access to public-facing applications affected by the vulnerability. Persistence is established, and lateral movement through the internal network will likely occur post-exploitation. In some cases, attackers must obtain specific SAML configuration values for exploitation, but it is unknown how easily this information can be obtained.
Ensure available patches are applied and risky or unnecessary services are not exposed to the Internet. Such items can be discovered through regular vulnerability scanning. Organizations should also ensure endpoints, especially those in DMZ networks, are protected and monitored via an Endpoint Detection & Response platform.
For a complimentary consultation, fill out the form below and we will be in touch soon.
Cisco is warning customers of the exploitation of CVE-2023-20269, a zero-day vulnerability that affects Cisco Adaptive Security Appliance (ASA) and Cisco Firepower Threat Defense (FTD). The exposure relates the VPN service and could allow an unauthorized attacker to perform brute-force attacks against accounts.
Exploitation leads to attackers being able to establish a clientless VPN session. Ransomware groups have reportedly targeted this flaw. Post-exploitation activity will likely include lateral movement and persistence, such as the creation of unknown accounts, malicious PowerShell activity, or the use of remote access software such as AnyDesk.
There is currently no fix available, but there are mitigation steps available. In addition to the layer of security multifactor authentication provides against brute-force attacks, mitigate risk with the following:

On September 7, 2023, Citizen Lab published a report on a “Zero-Click, Zero-Day Exploit” they refer to as “BLASTPASS”. The exploit was used to deploy Pegasus spyware on Apple iOS devices through images sent in iMessage. Apple disclosed two CVEs, CVE-2023-41064 and CVE-2023-41061, and patched devices as a result.
Pegasus spyware is known for its ability to ultimately compromise the communications of its victims. Pegasus likely contributed to the murder of journalist Jamal Kashoggi in 2018.
Install updates to apple iOS devices as soon as possible. For those who may be targets of nation-state-level actors, lockdown mode is an option. Note that lockdown mode severely impacts the usability of iOS devices.

In response to a data breach and ransomware event in February 2023, Minneapolis began notifying more than 100,000 people about leaked data. The data included Personally Identifiable Information (PII), which can be used to commit fraud against victims.
Cybersecurity is time-consuming and expensive. Recovering from a ransomware attack approaches financial devastation. The impact on the Minneapolis school district and its stakeholders has been significant.
If you are a school administrator, review and enhance your organization’s cybersecurity program immediately. All citizens can help by encouraging school boards and administrators to implement robust security programs.
