Kapeka is a backdoor written in C++ used against victims in Eastern Europe since at least mid-2022. Kapeka has technical overlaps with Exaramel for Windows and Prestige malware variants, both of which are linked to Sandworm Team. Kapeka may have been used in advance of Prestige deployment in late 2022.[1][2]

MITRE reference S1190
Kapeka utilizes AES-256 (CBC mode), XOR, and RSA-2048 encryption schemas for various configuration and other objects.4
Kapeka masquerades as a Microsoft Word Add-In file, with the extension .wll, but is a malicious DLL file.56
Kapeka will clear registry values used for persistent configuration storage when uninstalled.10
Standing S1190
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
Techniques1461st pct
61st percentile · 61% of 825 ATT&CK software entries have this many Enterprise techniques or fewer.
Tactics768th pct
68th percentile · 68% of 825 ATT&CK software entries have this many tactics spanned or fewer.
Threat group161% tie · 22 values
61% of the population shares a single value across only 22 distinct values, so a percentile here would rank the tie, not the entity.
Campaigns085% tie · 8 values
85% of the population shares a single value across only 8 distinct values, so a percentile here would rank the tie, not the entity.
