What is a phishing attack in cyber security?

In the realm of cyber security, a phishing attack entails a deceitful scheme whereby malicious "threat actors" impersonate trustworthy entities. Their objective? To acquire sensitive information, such as passwords, a credit card number or numbers and other financial details, from unsuspecting individuals.

In more sophisticated types of phishing attacks, threat actors employ a multitude of techniques, such as phone calls, suspicious emails, malicious websites, text messages, and other methods, to illicitly acquire confidential information for their benefit.

Phishing campaigns have been evolving with ever-increasing sophistication. These deceptive tactics now encompass the use of legitimate services or websites, accompanied by the tailoring of phishing links, to specifically target individuals or organisations.

To combat this evolving threat landscape, we are constantly upskilling ourselves – both as individuals and as an organisation, to serve our customers better. Just as threat actors are honing their skills to carry out more sophisticated attacks, we too must enhance our knowledge and defences.

Action you can take:

Despite these risks, MFA remains an effective security measure. Here are some guidelines to enhance your security while using MFA:

  • Use authenticator apps like Microsoft Authenticator instead of relying solely on text message codes.
  • Never share your security codes with anyone.
  • Create strong and unique passwords using password generators and use a password manager.
  • Avoid reusing passwords across multiple accounts.
  • Educate yourself and your employees about common social engineering tactics to recognise and avoid interactions with OTP bots.

How to prevent phishing attacks

In addition to the potential reputational-harm that can result from a security breach, especially in financial institutions or healthcare organisations - high profile examples of which we have seen recently, a phishing attack can also wreak havoc on your computer, mobile device, or network.
