Form-Based Phishing Attacks: All You Need to Know

Phishing methods have witnessed an evolution in the current landscape, coercing users into offering credentials. Researchers have warned people to keep an eye out for form-based phishing attacks where the threat actors imitate or abuse branded file-sharing, content-sharing, and productivity websites.

A quick run-through

Barracuda Networks, in its blog post, has stated that between January and April, these form-based phishing attacks impersonated Microsoft and Google services. In some variants, credential theft is not required - the attackers need to be granted access token.

Some statistics your way

  • These attacks comprised 4% of spear-phishing attacks - with approximately 100,000 cases in the first quarter of 2020.
  • Google storage and file sharing websites were leveraged 65% of the time, while Microsoft brands were leveraged 13% of the time. Other impersonated brands consisted of formcrafts.com (2%), mailchimp.com (4%), and sendgrid.net (10%).

The pandemic has given rise to a number of phishing attacks against enterprises, where the malicious actors have shown no regard for the ongoing crisis. Phishing scams are not a new threat, however, with the increasing sophistication in attack tactics and the current environment, these attacks have the highest potential of being effective.

Worth noting

  • The form-based phishing attacks are difficult to identify as the links point to legitimate websites.
  • Since the aim of these attacks is to steal credentials, the most probable result would be an account takeover, stated Klevchuk.

Stay safe

Phishing attacks are not going anywhere; hackers will evolve their techniques and form-based attacks are expected to go a long way. Nevertheless, organizations can take steps, such as implementing MFA, improving user security education, and deploying API-based inbox defense, to protect themselves and their customers against such attacks.
