## GuardDuty - Cryptocurrency Finding Types
|
|
|
|
| Finding Type | Signal |
|
|
|-------------|--------|
|
|
| `CryptoCurrency:EC2/BitcoinTool.B!DNS` | EC2 querying crypto domains |
|
|
| `CryptoCurrency:EC2/BitcoinTool.B` | EC2 communicating with mining pools |
|
|
| `CryptoCurrency:Runtime/BitcoinTool.B!DNS` | Container DNS to mining domain |
|
|
| `CryptoCurrency:Runtime/BitcoinTool.B` | Container network to mining pool |
|
|
| `Impact:EC2/BitcoinDomainRequest.Reputation` | Known mining domain access |
|
|
|
|
## GuardDuty CLI
|
|
|
|
```bash
|
|
# Get detector ID
|
|
aws guardduty list-detectors --query 'DetectorIds[0]' --output text
|
|
|
|
# List crypto findings
|
|
aws guardduty list-findings --detector-id $DET \
|
|
--finding-criteria '{"Criterion":{"type":{"Eq":["CryptoCurrency:EC2/BitcoinTool.B!DNS"]}}}'
|
|
|
|
# Get finding details
|
|
aws guardduty get-findings --detector-id $DET --finding-ids id1 id2
|
|
```
|
|
|
|
## AWS Cost Anomaly Detection
|
|
|
|
```bash
|
|
# Create cost anomaly monitor
|
|
aws ce create-anomaly-monitor --anomaly-monitor '{
|
|
"MonitorName": "EC2CostSpike",
|
|
"MonitorType": "DIMENSIONAL",
|
|
"MonitorDimension": "SERVICE"
|
|
}'
|
|
|
|
# Create alert subscription
|
|
aws ce create-anomaly-subscription --anomaly-subscription '{
|
|
"SubscriptionName": "CryptoAlert",
|
|
"MonitorArnList": ["arn:aws:ce::123456789012:anomalymonitor/monitor-id"],
|
|
"Subscribers": [{"Address": "soc@company.com", "Type": "EMAIL"}],
|
|
"Threshold": 100.0,
|
|
"Frequency": "IMMEDIATE"
|
|
}'
|
|
```
|
|
|
|
## Known Mining Pool Ports
|
|
|
|
```
|
|
3333 - Stratum protocol (common)
|
|
4444 - Mining proxy
|
|
5555 - Monero (XMR)
|
|
7777 - Alt-coin mining
|
|
8888 - Multi-pool
|
|
9999 - Mining proxy
|
|
14444 - XMRig default
|
|
45700 - MoneroOcean
|
|
```
|
|
|
|
## VPC Flow Logs Query (CloudWatch Insights)
|
|
|
|
```
|
|
fields @timestamp, srcaddr, dstaddr, dstport, action
|
|
| filter dstport in [3333, 4444, 5555, 7777, 14444, 45700]
|
|
| sort @timestamp desc
|
|
| limit 50
|
|
```
|
|
|
|
## EC2 Instance Remediation
|
|
|
|
```bash
|
|
# Terminate mining instance
|
|
aws ec2 terminate-instances --instance-ids i-0123456789abcdef0
|
|
|
|
# Revoke security group ingress on mining ports
|
|
aws ec2 revoke-security-group-ingress --group-id sg-xxx \
|
|
--protocol tcp --port 3333 --cidr 0.0.0.0/0
|
|
```
