Positional arguments

Target

Specify one or more target URIs.

If target URI points to a server, all its endpoints will be scanned.

If target URI points to a Local Discovery Server (LDS) or Global Discovery Server (GDS), all endpoints listed in them will be scanned.

Currently only ocp.tcp scheme is supported.

OPC URL format

Flags

-i, --input-file=VALUE

Specify a file to read OPC UA Discovery URIs from. The file shall have one URI per line. The special value - causes URIs to be read from stdin.

-o, --output=VALUE

Specify filename for output report. If unspecified, OpalOPC will generate a name for it. The special value - causes report to be printed to stdout.

-v

Increase output verbosity. Can be specified multiple times to further increase it. Currently the maximum verbosity is reached by using this flag 2 times.

-h, --help

-s

Silence all output. This is useful with -o -.

-l, --login-credetial=VALUE

Specify a single username:password for user authentication. Can be specified multiple times to add multiple credentials.

-b, --brute-force-credential=VALUE

Specify a single username:password for user authentication brute force attack. Can be specified multiple times to add multiple credentials.

-L, --login-credential-file=VALUE

Specify a file to read multiple username:password from for user authentication. The file shall have one credential per line.

-B, --brute-force-credential-file=VALUE

Specify a file to read multiple username:password from for user authentication brute force attack. The file shall have one credential per line.

-c, --user-certificate-and-privatekey=VALUE

Specify path-to-certificate:path-to-privatekey for user authentication. The files shall be in PEM format. Can be specified multiple times to add multiple credentials.

-a, --application-certificate-and-privatekey=VALUE

Specify path-to-certificate:path-to-privatekey for application authentication. The files shall be in PEM format. Can be specified multiple times to add multiple credentials.

-d, --discovery

Run network discovery through mDNS and exit. Prints discovered OPC UA Discovery URLs to stdout.

--version

Show version and exit.

Examples

Scan single DiscoveryUrl for OPC UA applications

opalopc opc.tcp://scanme.opalopc.com:53530

Scan 2 DiscoveryUrls

opalopc opc.tcp://echo:53530 opc.tcp://foxtrot:48010

Scan all DiscoveryUrls in file, produce report with custom name

opalopc -i discoveryuris.txt -o vulnerability-report.html

Read stdin for DiscoveryURLs and print report to stdout

opalopc -s -i - -o -

Scan with application certificate and credential pair

opalopc -a /tmp/certificate.pem:/tmp/privkey.pem -l opcadmin:v3rys3cr3t123! opc.tcp://scanme.opalopc.com:53530

Discover targets on network

opalopc -d

Debug output

opalopc -v opc.tcp://scanme.opalopc.com:53530

Trace output (most detailed)

opalopc -vv opc.tcp://scanme.opalopc.com:53530
