Rise in Phone Scams: Impersonating NAB Staff Exposes Vulnerabilities in Cybersecurity

Phone scams have long been a concern, but the recent emergence of Artificial Intelligence (AI) voices adds a new layer of complexity to this issue. AI technology enables scammers to convincingly mimic the voices of trusted individuals, making it increasingly difficult to differentiate between genuine and fraudulent callers. These AI-generated voices can be remarkably lifelike, making it easier for scammers to manipulate victims and gain their trust.

Phone Scam

In a disturbing trend, three scams in the span of just five (5) days have highlighted the growing threat of scammers impersonating National Australia Bank (NAB) staff to gain unauthorised access to accounts over the phone. Victims include two settlement agents and one real estate agent who, unfortunately, fell prey to this insidious phone scam. The perpetrators of these scams are often articulate and armed with personal details, such as account information and mobile numbers. They may even go as far as sending impersonated two-factor authentication messages. As cybercriminals continue to exploit advancements in technology, it is imperative for individuals and institutions alike to be vigilant and take appropriate precautions.


The impersonation of local people is another worrisome aspect of these scams. By using AI voices, scammers can now imitate accents and dialects, further blurring the line between authenticity and deceit. This tactic not only increases the chances of success but also creates a sense of familiarity, leading victims to lower their guard.


These scams highlight the pressing need for improved cybersecurity measures, both at the individual and organisational levels. To protect oneself against such fraudulent activities, it is crucial to remain aware and adopt preventive measures:

  1. Be sceptical: Exercise caution when receiving unsolicited phone calls, especially if they involve sensitive information or urgent requests. Remember that legitimate institutions like banks and the government institutions would never ask for account details, or passwords over the phone.

  2. Verify the caller’s identity: If someone claims to be from your bank or any other organisation, ask for their name, department, and contact information. Hang up and independently verify their identity by calling a known number or referring to official statements or documentation.

  3. Guard personal information: Avoid sharing sensitive information, such as account numbers, passwords, or PINs, over the phone or through email. Genuine institutions will have secure channels for such communication.

  4. Enable two-factor authentication: Activate and regularly update two-factor authentication for all your online accounts, including banking and email. This provides an extra layer of security by requiring a second verification step, making it more challenging for scammers to gain unauthorised access. Try to avoid using SMS as a two-factor authentication method as this method can be impersonated.

  5. Educate yourself and others: Stay informed about the latest scam techniques and share this knowledge with friends, family, and colleagues. Awareness is a crucial weapon in the fight against cybercrime.

  6. Report suspicious activities: If you encounter a scam or suspect fraudulent behaviour, report it immediately to your bank, local law enforcement, and relevant consumer protection agencies. By reporting these incidents, you not only protect yourself but also contribute to the larger effort of combating cybercrime.

The recent surge in phone scams impersonating NAB staff serves as a stark reminder of the ever-evolving nature of cyber threats. As scammers leverage AI voices and impersonate local individuals, it becomes increasingly challenging to discern between genuine and fraudulent calls. Staying vigilant, adopting preventive measures, and fostering a culture of cybersecurity awareness are crucial steps towards protecting ourselves and our communities from these scams.


Remember, when it comes to sensitive information and financial matters, it is always better to err on the side of caution. If in doubt, hang up and independently verify the caller’s identity. Safeguarding our personal information and staying one step ahead of scammers are essential in the digital age we live in today.
