Havoc is an open-source post-exploitation command and control (C2) framework first released on GitHub in October 2022 by C5pider (Paul Ungur), who continues to maintain and develop it with community contributors. Havoc provides a wide range of offensive security capabilities and has been adopted by multiple threat actors to establish and maintain control over compromised systems.
Enterprise ATT&CK only. Any Mobile or ICS rows on the same ATT&CK page are not carried.
MITRE reference S1229
Havoc has a module for network enumeration including determining IP addresses.3
The Havoc demon can check for a connection to the C2 server from the target machine.4
Havoc has utilized XOR encryption with the key “01-01-1900” to obfuscate command strings.6
Havoc can trigger exection of whoami on the target host to display the current user.78
Standing S1229
Reach is how much of ATT&CK this tool touches. Coverage is how well defended each thing it does is, as a median per technique rather than a total — a total would just restate the reach. Each figure is ranked against all 825 ATT&CK software entries only where that population actually spreads. Where most of the population shares one value, a percentile would rank the tie instead of the entity, so the raw value is shown and no rank is claimed.
Reach
91st percentile · 91% of 825 ATT&CK software entries have this many Enterprise techniques or fewer.
80th percentile · 80% of 825 ATT&CK software entries have this many tactics spanned or fewer.
61% of the population shares a single value across only 22 distinct values, so a percentile here would rank the tie, not the entity.
85% of the population shares a single value across only 8 distinct values, so a percentile here would rank the tie, not the entity.
Coverage
34th percentile · 66% of 825 ATT&CK software entries have more detection rules per technique.
Detection coverage S1229
1009 distinct rules cover the 29 techniques recorded for this tool. The 1108 technique-to-rule mappings resolve to 1009 distinct rules, because one rule can cover several techniques. 726 Sigma · 283 Splunk.
