These matching email records were observed previously, but they may already have been addressed or may no longer be valid. The device count estimates infected devices associated with these email records; it is not the number of devices owned by the organization.
Frequently asked questions
What affects the security of www.ccasn.berkeley.edu?
A valid SSL certificate still does not prove that www.ccasn.berkeley.edu is safe, legitimate, or free of scam signals. For a more complete assessment, this report also checks phishing and malware, exposed email records, IPs and open ports, subdomains, technologies, and CVEs that may apply to observed versions.
Does www.ccasn.berkeley.edu use HTTPS, and is its SSL certificate valid?
HTTPS on www.ccasn.berkeley.edu presented a certificate that was invalid or failed verification. The operator should review its validity dates, domain names, and trust chain.
Have @berkeley.edu email addresses appeared in exposed data or information-stealer (infostealer) logs?
Data sources
Data compiled from CyStack cybersecurity monitoring systems
CyStack compiles scan results from its internal cybersecurity monitoring systems, including CyStack VulnScan and CyStack Threat Intelligence, together with publicly available Internet data. The assessment only observes and analyzes information already available; it does not attempt unauthorized access, test passwords, send exploit code, or change or disrupt the assessed system.
These 3 failed checks or warnings have the greatest impact on the result for www.ccasn.berkeley.edu.
Certificate matches the websiteThe certificate does not match the requested target.Critical
Why it matters
The certificate must list the exact hostname visitors requested in its Subject Alternative Names (SAN). A mismatch produces browser warnings because the certificate may belong to a different service.
What to do
Issue and deploy a certificate whose SAN list includes every public hostname served by this website address.
Diagnostic information
The available certificate evidence was not sufficient to conclude this certificate requirement.
Public management service exposureA confirmed public management service was found: 173.236.244.36:22 (ssh).High
Why it matters
Remote administration services such as RDP, VNC, Docker, Kubernetes, and management consoles are high-value targets. Public exposure allows anyone on the Internet to attempt passwords or exploit an unpatched service.
What to do
Remove direct Internet access and require a VPN, a hardened access gateway, or trusted source networks; also use MFA where supported.
Unencrypted legacy serviceA confirmed public legacy cleartext service was found: 173.236.244.36:21 (ftp).High
Why it matters
Older services such as Telnet, FTP, and unencrypted mail or directory protocols can send passwords and data in readable form. Anyone able to observe the network path may capture them.
What to do
Disable the legacy service or replace it with an encrypted alternative such as SSH, SFTP, HTTPS, or the secure version of the mail protocol.

Which public IPs, services, and ports does www.ccasn.berkeley.edu expose?
The assessment observed 1 public IPs and 6 open ports for www.ccasn.berkeley.edu. An open port is not the same as a vulnerability, but the website owner should keep every public service updated and appropriately restrict access.
How many subdomains of berkeley.edu have been discovered?
The assessment observed 1,209+ public subdomains of berkeley.edu. This list can reveal additional entry points such as APIs, administration systems, or test environments, but it does not mean that every subdomain is risky.
