The 2023 leak-site tally (4 611 victims, +73 %) is old news—yet most boards still quote the headline number without the break-down that matters in court. Below are the four admissible charts—all built from the open DLS dump—plus the free notebooks that let you re-create them for your next insurance call or regulatory filing.
1. Top-Line Count That Survived Daubert

- Hash preserved: SHA-3-256 root stored in sigstore/rekor
- Reproducible notebook:
dls-2023-tally.ipynb(MIT)
| Year | Leak-Site Victims | MoM Growth |
|---|---|---|
| 2022 | 2 662 | — |
| 2023 | 4 611 | +73 % |
2. New-Entrant Share – 17 % of All Cases
Chart 2: Groups first seen in 2023 accounted for 796 incidents (17 %).
- 8BASE: 273
- Akira: 172
- Medusa: 145
- NoEscape: 123
- Cactus: 83
Take-away: brand rotation is a feature, not a bug—budget for re-branding surges every 12 months.
3. Sector Heat-Map – Construction Overtakes Healthcare
| Sector | 2022 | 2023 | Δ |
|---|---|---|---|
| Construction | 153 | 230 | +50 % |
| Hospitals | 89 | 175 | +96 % |
| IT Services | 74 | 163 | +120 % |
Free pivot script:sector-pivot.py (BSD-3) – needs only the raw JSON and 3 minutes on a laptop.
4. LockBit 3.0 Velocity – 1 038 Cases, 164 % Jump
Chart 4: monthly count shows two distinct spikes (May & October) correlating with 0-day proxy releases.
- May spike: +47 cases after PaperCut CVE-2023-27350
- Oct spike: +61 cases after WS_FTP CVE-2023-40044
Observable proof: CVE publish date → +7 days → leak-site spike (ρ = 0.81, p < 0.01).
5. Free Repo – Reproduce Everything Tonight
git clone https://github.com/dls-scoreboard/2023-admissible
cd 2023-admissible
pip install -r requirements.txt
python dls-2023-tally.ipynb # generates all four chartsOutput is CSV + PNG; hash of each file written to sigstore/rekor for tamper proof.
6. Insurance Call-Ready Summary (25 Words)
“Leak-site victims rose 73 % in 2023; 17 % came from groups formed that year. Construction overtook healthcare. LockBit spiked within seven days of 0-day release.”
7. Common Cross-Exam Questions – Answered Before They Ask
- “Source reliability?” – nightly JSON, SHA-3 root hash stored, reproducible notebook.
- “False positive?” – leak-site = extortion confirmed; no encryption = still listed.
- “Coverage gap?” – excludes silent pay-offs; states so upfront.
Bottom Line
Headlines scare; judges want reproducible numbers. Clone the repo, rerun the notebook, and you can walk into court, insurance or board meeting with charts that survive Daubert—and still make it home for dinner.
