Accenture Security APEX Labs
IOCs & detection
We publish findings from Accenture Cyber Intelligence research to help defenders detect and respond to active threats. Reports bring together indicators of compromise, YARA detection rules, network fingerprints and mitigation guidance, ready to use in your own tools. All content is TLP:CLEAR, so you're free to use and share it.
Published reports
What reports include
Threat analysis
Technical findings on malware and attacker tooling
Indicators
File hashes and IP addresses of known threat activity
Detection rules
YARA rules for files and memory on Windows and Linux
Network fingerprints
JA4 and JA3 TLS fingerprints and protocol indicators
Mitigation
Practical guidance for detection and response
Using this intelligence
Indicators
Add the sample hashes to EDR blocklists and SIEM watchlists, and search historical endpoint telemetry for earlier executions. Add IP addresses to firewall and proxy blocklists, and search network and authentication logs for past connections.
IP addresses are published defanged (for example, 23.95.119[.]178): replace [.] with . before loading them.
Network fingerprints
Alert on the JA4 and JA3 fingerprints in your NDR or SIEM pipeline, and prefer JA4 where your tooling supports it. Other software built on the same TLS library can share a fingerprint, so check destination, SNI and host context before blocking.
YARA rules
Copy a rule from its report page, save it as a .yar file and run it with the YARA command-line tool. You can also load it into any EDR, sandbox or file-scanning pipeline that accepts YARA rules.
# Scan a directory recursively and print the matching strings
yara -r -s rule.yar /path/to/scan
# Scan the memory of a running process (usually needs administrator or root rights)
yara -s rule.yar <PID>
Some rules import YARA modules such as pe or elf, which are included in standard YARA builds.
Mitigation guidance
Each report ends with recommendations specific to the threat. Use them to prioritise hardening and monitoring work.
Test before you block
Run new rules in alert-only mode first to measure false positives in your environment.
Sharing and feedback
Traffic Light Protocol
All content on this site is marked TLP:CLEAR under FIRST TLP 2.0. Recipients may share it without restriction, subject to standard copyright rules.
You are welcome to load the indicators and rules into your own tools and to redistribute them. Please credit Accenture Security APEX Labs. Keep the rule metadata (author, date, version) intact so others can trace updates.
Feedback
If a rule produces false positives, misses a sample it should catch, or a report contains an error, please open an issue on GitHub. Include the report and rule name, the rule version, your YARA version, and the SHA-256 of any file involved.
Do not attach malware samples to issues, and do not post client, personal or other sensitive data.
