"Global Networks Under Siege: Massive Brute-Force and Zero-Day Attacks Unleashed"

Cisco's Talos security team has issued a warning about a widespread credential compromise campaign targeting VPNs, SSH, and web applications, with attacks originating from nearly 4,000 IP addresses. The attacks involve both generic and specific usernames, and the IP addresses appear to come from anonymizing tunnels and proxies. The campaign is indiscriminate and opportunistic, posing risks of unauthorized network access, account lockouts, and denial-of-service conditions. Cisco has provided a list of recommendations for preventing these attacks and has added the IP addresses to a block list for its VPN offerings.
