2013-06-18 - NEUTRINO EK FROM 199.195.249.188 - 1208B83B81C141ECD6F05E24.WEBHOP.ORG:8000
PCAP AND MALWARE:
- ZIP file of the PCAP: 2013-06-18-Neutrino-EK-traffic.pcap.zip
- ZIP file of the malware: 2013-06-18-Neutrino-EK-malware.zip
NOTES:
- This was my first blog entry, back when I began documenting exploit kit (EK) traffic, and I didn't realize this was Neutrino EK.
- The malware payload was obfusated, XOR-ed with the ASCII string: nylhvw (something I hadn't figured out yet).
- This PCAP is dated 2013-06-19 in UTC, which was 2013-06-18 Central time in the US (which is why this blog entry is dated 2013-06-18).
- On 2014-09-20, I updated this blog entry with more information, and changed the format to how I now report on EK traffic.
