Cisco Talos shared the newest rule update for SNORTⓇ this afternoon.
Tuesday's release includes new protection against the BlackMatter ransomware attack. Japanese technology company Olympus recently suffered an attack from this group, suffering outages across its European, Middle East and Africa computer networks. BlackMatter also recently infected a large grain co-op in Iowa, with the group demanding a $5.9 million ransom payment.
Here's a full breakdown of Thursday's rule update:
| Shared object rules | Modified shared object rules | New rules | Modified rules |
|---|---|---|---|
| 4 | 0 | 13 | 5 |
Talos has added and modified multiple rules in the file-other, malware-other, malware-tools, protocol-other and server-webapp rule sets to provide coverage for emerging threats from these technologies.
