Critical Vulnerability in Citrix Netscaler

Criminal threat groups and nation-state actors are exploiting a critical vulnerability in Citrix Netscaler ADC and Netscaler Gateway, leading to attacks on organizations worldwide. The vulnerability, CitrixBleed, has been linked to major attacks including the exfiltration of sensitive data from Boeing's parts and distribution unit. The Industrial & Commercial Bank of China was recently debilitated by a ransom hack connected to the Citrix vulnerability. The U.S. government's cybersecurity agency has advised federal agencies to patch against the actively exploited flaw, with several threat groups believed to be leveraging CitrixBleed for large-scale breaches.
