Keypoints
- Large-scale network scans have been probing Cisco ASA login portals and Cisco IOS Telnet/SSH interfaces.
- The activity, mainly from a Brazilian botnet, suggests reconnaissance for potential exploits or vulnerabilities.
- Most scans targeted the United States, with activity also observed in the UK and Germany.
- Such scans often precede the disclosure of new security flaws or attempted exploitation of patched bugs.
- Organizations are advised to update Cisco devices, enforce multi-factor authentication, and use additional access controls to mitigate risks.
