[doctor/master] Script to check for fingerprint changes

commit 6ad1ce1e3d9f1d088fab8fcc55b7ea9712c9cc42 Author: Damian Johnson <atagar(a)torproject.org> Date: Sun Oct 4 13:25:29 2015 -0700 Script to check for fingerprint changes During our recent dev meeting David Goulet asked me for a DocTor check for relays rapidly changing their fingerprint. Doing so likely means they're trying to get into a privilaged position to snoop on hidden services. Plan is to keep an eye on this script for a bit (just whipped it up, no doubt it has issues), then send the results to David when we have some confidence in it. Later the results will be sent to bad-relays@. --- .gitignore | 1 + consensus_health_checker.py | 2 +- descriptor_checker.py | 2 +- fingerprint_change_checker.py | 128 +++++++++++++++++++++++++++++++++++++++++ sybil_checker.py | 6 +- 5 files changed, 134 insertions(+), 5 deletions(-) diff --git a/.gitignore b/.gitignore index 1a47934..c320e41 100644 --- a/.gitignore +++ b/.gitignore @@ -3,6 +3,7 @@ logs/ data/contact_information.cfg data/fingerprints +data/fingerprint_changes data/last_notified.cfg stem gmail_pw diff --git a/consensus_health_checker.py b/consensus_health_checker.py index 8733cb4..82c21c7 100755 --- a/consensus_health_checker.py +++ b/consensus_health_checker.py @@ -742,7 +742,7 @@ def _get_documents(label, resource): for authority, query in queries.items(): try: documents[authority] = query.run()[0] - except Exception, exc: + except Exception as exc: if label == 'vote': # try to download the vote via the other authorities diff --git a/descriptor_checker.py b/descriptor_checker.py index 8050ca8..434b4d6 100755 --- a/descriptor_checker.py +++ b/descriptor_checker.py @@ -95,7 +95,7 @@ def send_email(subject, descriptor_type, query): try: timestamp = datetime.datetime.now().strftime("%m/%d/%Y %H:%M") util.send(subject, body = EMAIL_BODY % (descriptor_type, query.download_url, timestamp, query.error), to = [util.ERROR_ADDRESS]) - except Exception, exc: + except Exception as exc: log.warn("Unable to send email: %s" % exc) diff --git a/fingerprint_change_checker.py b/fingerprint_change_checker.py new file mode 100755 index 0000000..289f3c0 --- /dev/null +++ b/fingerprint_change_checker.py @@ -0,0 +1,128 @@ +#!/usr/bin/env python +# Copyright 2015, Damian Johnson and The Tor Project +# See LICENSE for licensing information + +""" +Simple script that checks to see if relays rapidly change their finterprint. +This can indicate malicious intent toward hidden services. +""" + +import datetime +import time +import traceback + +import util + +from stem.descriptor.remote import DescriptorDownloader +from stem.util import datetime_to_unix, conf + +EMAIL_SUBJECT = 'Relays Changing Fingerprint' + +EMAIL_BODY = """\ +The following relays are frequently changing their fingerprints... + +""" + +FINGERPRINT_CHANGES_FILE = util.get_path('data', 'fingerprint_changes') +THIRTY_DAYS = 30 * 24 * 60 * 60 + +log = util.get_logger('fingerprint_change_checker') + + +def main(): + fingerprint_changes = load_fingerprint_changes() + downloader = DescriptorDownloader(timeout = 60) + alarm_for = [] + + for relay in downloader.get_consensus(): + prior_fingerprints = fingerprint_changes.setdefault((relay.address, relay.or_port), {}) + + if relay.fingerprint not in prior_fingerprints: + log.debug("Registering a new fingerprint for %s:%s (%s)" % (relay.address, relay.or_port, relay.fingerprint)) + prior_fingerprints[relay.fingerprint] = datetime_to_unix(relay.published) + + # drop fingerprint changes that are over thirty days old + + for fp in prior_fingerprints: + if time.time() - prior_fingerprints[fp] > THIRTY_DAYS: + log.debug("Removing fingerprint for %s:%s (%s) which was published %i days ago" % (relay.address, relay.or_port, fp, prior_fingerprints[fp] / 60 / 60 / 24)) + del prior_fingerprints[fp] + + # if we've changed more than three times in the last thirty days then alarm + + if len(prior_fingerprints) >= 3: + alarm_for.append((relay.address, relay.or_port)) + + if alarm_for: + log.debug("Sending a notification for %i relays..." % len(alarm_for)) + body = EMAIL_BODY + + for address, or_port in alarm_for: + fp_changes = fingerprint_changes[(address, or_port)] + log.debug("* %s:%s has had %i fingerprints: %s" % (address, or_port, len(fp_changes), ', '.join(fp_changes.keys()))) + body += "* %s:%s\n" % (address, or_port) + + for fingerprint, published in fp_changes.items(): + body += " %s at %s\n" % (fingerprint, datetime.datetime.fromtimestamp(published).strftime('%Y-%m-%d %H:%M:%S')) + + body += "\n" + + try: + util.send(EMAIL_SUBJECT, body = body, to = ['atagar(a)torproject.org']) + except Exception as exc: + log.warn("Unable to send email: %s" % exc) + + save_fingerprint_changes(fingerprint_changes) + + +def load_fingerprint_changes(): + """ + Loads information about prior fingerprint changes we've persisted.
