Security and Risk Management

Full Answer Section

• Were there any controls implemented against the vulnerability and yet it was exploited? It's impossible to say definitively without more information. However, the fact that a successful attack occurred suggests that existing controls may not have been sufficient or properly implemented.

2. Analysis and Action

• When and how did the target figure out about the attack? The exact timeline is unclear, but Optus publicly acknowledged the data breach on September 21st, 2022. It's likely they became aware of the intrusion internally before the public announcement.
• For how long, the risk was not actioned? Again, the exact timeframe is unknown. However, the successful attack indicates that the vulnerability existed for some time before being exploited.
• Did the organisation have a risk assessment policy and procedure? Optus certainly should have had a risk assessment policy and procedure in place. Having such a policy would involve identifying potential vulnerabilities, assessing the likelihood and impact of potential attacks, and implementing controls to mitigate those risks. Whether these procedures were followed and adequate or not remains under investigation.

Additional Notes

• The Optus data breach was a significant event in Australia, affecting millions of customers.
