You Should Know: How to Detect and Avoid Tax-Related Phishing
1. Verify Suspicious Domains
Use tools like:
- WHOIS Lookup: Check domain registration details.
whois example.com
- VirusTotal: Scan URLs for malicious activity.
curl -X POST --url 'https://www.virustotal.com/vtapi/v2/url/scan' --form 'apikey=YOUR_API_KEY' --form 'url=URL_TO_CHECK'
2. Inspect SSL Certificates
Legitimate tax sites use valid SSL certificates. Verify with OpenSSL:
openssl s_client -connect example.com:443 | openssl x509 -noout -text
Look for issuer details and expiration dates.
3. Analyze Network Connections
Use `tcpdump` to monitor suspicious traffic:
sudo tcpdump -i eth0 'host malicious-domain.com' -w traffic.pcap
4. Block Malicious Domains via Hosts File
Add phishing domains to `/etc/hosts` to block access:
echo "0.0.0.0 malicious-domain.com" | sudo tee -a /etc/hosts
5. Report Phishing Attempts
- IRS Reporting: Forward phishing emails to [email protected].
- CISA: Submit malicious URLs to https://www.cisa.gov/report.
