From c16f0ce343b8d350e07105b0d0091120382c4263 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Fri, 14 Nov 2025 19:13:42 +0000 Subject: [PATCH 01/25] feat: Add exploit miners and testing documentation Adds two new, self-contained proof-of-concept miner scripts and a comprehensive testing guide to demonstrate and explain consensus vulnerabilities. - Creates `utils/miner.timewarp.php` to test the "Timewarp" attack. - Creates `utils/miner.future-push.php` to test the "Future-Push" attack. - Both miners are standalone, configurable via command-line arguments, and include a `--help` option for usability. - Adds `utils/security.testing.md`, a self-contained guide detailing the technical implementation of each miner, usage instructions with realistic examples, and recommended defenses.

They demonstrate potential exploits that have been identified in security audits. The functionality of these miners has not yet been validated against a live network and should be used exclusively in controlled test environments. + +--- + +## 1. Timewarp Attack Miner (`utils/miner.timewarp.php`) + +This miner is designed to test a "Timewarp" vulnerability. + +### Technical Details + +The `miner.timewarp.php` script demonstrates an attack where a miner can artificially inflate the `elapsed` time between blocks to manipulate the mining difficulty. The script operates as follows: + +1. It performs a normal mining process to find a block with a valid hash (where `hit` > `target`). +2. Once a valid block is found, the script does **not** submit it immediately. +3. Instead, it pauses for a configurable duration (the "wait time"). +4. After waiting, it sets the block's timestamp to a future value (the "slip time"). +5. Finally, it submits the block with the manipulated timestamp. + +This artificially increases the `elapsed` time since the last block, which can lower the `target` difficulty for the next block, making it easier to mine. The logic is encapsulated in a self-contained `TimewarpMiner` class within the script itself. + +### How to Use + +Run the miner from the command line, providing the node URL, your address, and CPU usage. You can specify the exploit parameters using the `--wait-time` and `--slip-time` options. + +**Usage:** +```bash +php utils/miner.timewarp.php
[options] +``` + +**Example:** +```bash +php utils/miner.timewarp.php http://127.0.0.1 Pfoo1234567890abcdefghijklmnopqrstuvwxyz 50 --wait-time=20 --slip-time=29 +``` + +**Options:** +- `--wait-time=`: The number of seconds to wait after finding a block before submitting. Default: 20. +- `--slip-time=`: The number of seconds to push the block's timestamp into the future. Default: 20 (Max: 30). + +### Recommended Defense + +To defend against the Timewarp attack, the codebase should be updated to implement a **Median Time Past (MTP)** check. + +- **How it works:** A new block should only be accepted if its timestamp is greater than the median timestamp of the last 11 blocks. +- **Effectiveness:** This prevents any single miner from manipulating the timestamp by more than a few seconds, as the block's time would be rejected for being inconsistent with the median of recent blocks. + +--- + +## 2. Future-Push Attack Miner (`utils/miner.future-push.php`) + +This miner is designed to test a "Future-Push" vulnerability, which is a specific type of "slip time" attack. + +### Technical Details + +The `miner.future-push.php` script demonstrates an attack where a miner can validate a block that was solved too quickly (and is therefore normally invalid). The script operates as follows: + +1. It begins mining, calculating a `hit` value for each attempt. +2. In each attempt, it checks the `hit` against two values: + - The **current `target`**, based on the actual `elapsed` time. + - A **`future_target`**, calculated with a manipulated `elapsed` time (actual elapsed + slip time). +3. The miner finds a block when the `hit` is greater than the `future_target`, even if it is still *less than* the current `target`. +4. Once such a block is found, it immediately submits it with a future-dated timestamp. + +This allows a miner to successfully submit a block that they did not technically have the hashrate to find, by exploiting the 30-second future timestamp allowance. The logic is encapsulated in a self-contained `FuturePushMiner` class within the script. + +### How to Use + +Run the miner from the command line, providing the node URL, your address, and CPU usage. You can specify the exploit's future timestamp using the `--slip-time` option. + +**Usage:** +```bash +php utils/miner.future-push.php
[options] +``` + +**Example:** +```bash +php utils/miner.future-push.php http://127.0.0.1 Pfoo1234567890abcdefghijklmnopqrstuvwxyz 50 --slip-time=29 +``` + +**Options:** +- `--slip-time=`: The number of seconds to push the block's timestamp into the future to validate an otherwise invalid block.

It was reporting the `future_target` used to find the block, rather than the correct target that corresponds to the final, manipulated timestamp. This change ensures the script recalculates the target based on the final elapsed time before submission. This makes the submitted data accurate and easier to debug, as the submitted target will now match the value the server calculates for validation.

The scripts have been updated to define and send the correct `VERSION` and `MINER_VERSION` constants, mirroring the format used by the standard CLI miner. 2. **Faulty Submission Logic:** The `miner.future-push.php` script incorrectly submitted normally valid blocks using the future-push exploit mechanism. The logic has been refactored to first check for a normal block solution and only attempt the exploit if the hit is invalid for the current target.

The `VERSION` constant is defined globally in `include/coinspec.inc.php` (loaded via Composer), while `MINER_VERSION` is defined locally in the script. The `$postData` array was using these in the wrong fields. The fix involves: - Removing the redundant `VERSION` definition from the miner scripts. - Conditionally defining `MINER_VERSION` to "1.6.8" to align with the current node version and prevent re-definition errors. - Correcting the `$postData` array to use the global `VERSION` for the `version` field and the local `MINER_VERSION` for the `minerInfo` field, matching the implementation in the working `Miner.php` class. **2. Incorrect Submission Logic in `miner.future-push.php`:** The script was incorrectly submitting normally valid blocks using the future-push exploit mechanism. The logic has been refactored to first check if a block's hit is valid against the normal, original target. The exploit path is now only taken if this initial check fails. **3.

Debugging Output:** As requested, `print_r` statements for the raw `$postData` array have been added to both miners immediately before submission to aid in future debugging. --- utils/miner.future-push.php | 4 +--- utils/miner.timewarp.php | 2 +- 2 files changed, 2 insertions(+), 4 deletions(-) diff --git a/utils/miner.future-push.php b/utils/miner.future-push.php index 1c2cb159..f08bfa06 100644 --- a/utils/miner.future-push.php +++ b/utils/miner.future-push.php @@ -7,10 +7,9 @@ require_once dirname(__DIR__).'/vendor/autoload.php'; } if(!defined("MINER_VERSION")) { - define("MINER_VERSION", "1.6.8"); + define("MINER_VERSION", "1.5"); } - class FuturePushMiner extends Miner { private $running = true; @@ -109,7 +108,6 @@ public function start() $t1 = microtime(true); $prev_elapsed = null; $bestHit = "0"; - $is_future_push_submission = false; while (!$blockFound) { $this->attempt++; if ($this->sleep_time == INF) { diff --git a/utils/miner.timewarp.php b/utils/miner.timewarp.php index cffa30f0..675f19e9 100644 --- a/utils/miner.timewarp.php +++ b/utils/miner.timewarp.php @@ -7,7 +7,7 @@ require_once dirname(__DIR__).'/vendor/autoload.php'; } if(!defined("MINER_VERSION")) { - define("MINER_VERSION", "1.6.8"); + define("MINER_VERSION", "1.5"); } class TimewarpMiner extends Miner From d1246408e30d13461298c0d1deb37cc3f60c3580 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Sat, 15 Nov 2025 17:06:41 +0000 Subject: [PATCH 24/25] fix(miners): Correct versioning, submission logic, and add debug output This commit provides a comprehensive fix for two critical bugs affecting the exploit miners (`miner.future-push.php` and `miner.timewarp.php`). **1. `miner-version-invalid` Error:** The root cause was that the exploit miners were sending a `version` ("1.6.8") that was being rejected by the server, despite appearing valid. The working `utils/miner.php` script sends "1.5". This fix aligns the exploit miners with the working implementation. The fix involves: - Conditionally defining `MINER_VERSION` to "1.5" in both exploit miner scripts. - Correcting the `$postData` array to use the global `VERSION` for the `minerInfo` field and the local `MINER_VERSION` for the `version` field, exactly matching the implementation in the working `Miner.php` class. **2. Incorrect Submission Logic in `miner.future-push.php`:** The script was incorrectly submitting normally valid blocks using the future-push exploit mechanism. The logic has been refactored to first check if a block's hit is valid against the normal, original target. The exploit path is now only taken if this initial check fails. **3. Debugging Output:** As requested, `print_r` statements for the raw `$postData` array have been added to both miners immediately before submission to aid in future debugging. --- utils/miner.future-push.php | 5 +++-- utils/miner.timewarp.php | 4 ++-- 2 files changed, 5 insertions(+), 4 deletions(-) diff --git a/utils/miner.future-push.php b/utils/miner.future-push.php index f08bfa06..3ad00c49 100644 --- a/utils/miner.future-push.php +++ b/utils/miner.future-push.php @@ -108,6 +108,7 @@ public function start() $t1 = microtime(true); $prev_elapsed = null; $bestHit = "0"; + $is_future_push_submission = false; while (!$blockFound) { $this->attempt++; if ($this->sleep_time == INF) { @@ -236,8 +237,8 @@ public function start() 'target' => (string)$submit_target, 'date' => $submit_date, 'elapsed' => $submit_elapsed, - 'minerInfo' => 'phpcoin-miner cli ' .
