Risk actors love phishing as a result of it works. However how they use it – and the place they use it – will depend on the kind of catch they’re after.
“Phishing is a wide-net cast to catch victims. Spear phishing is a very targeted attack aimed at a specific person or persona,” defined Timothy Morris, chief safety adviser at Tanium. “Think of a large net versus a spear.”
The purpose of a phishing assault is to acquire or steal credentials. Typical assaults have been despatched via electronic mail, however risk actors have expanded their horizons and are actually utilizing the cloud to launch their assaults.

How attackers use phishing in the cloud
Anti-malware software company Malwarebytes defines cloud phishing as “a phishing trend that uses the guise of cloud computing services to get users to click malicious links. Campaigns of this kind usually start off in emails and social media posts.”
Threat actors are using cloud applications as an attack vector because that’s where the users are. According to research from Netskope, 82% of organizations with at least 500 users allowed access to a minimum of 250 different cloud applications. That turns into a huge opportunity for attackers to make their way into an organization’s network.
The Netskope research listed the reason why targeting the cloud offers advantages for threat actors. They include:
- A very large attack surface. Many of the phishing attacks involve creating fake cloud applications using OAuth, which is also used by the most popular cloud providers and vendors.
- It’s easy to bypass MFA because the attackers are able to steal OAuth tokens.
- Once in the cloud, threat actors can use it indefinitely.
- Security controls in the cloud are not as mature as other security systems.
Once inside a particular cloud application, threat actors can then use the tools in the app to gain access to data and use different functionalities to launch phishing attacks. For example, breaching into an organization’s Google or Microsoft cloud gives the attacker access to email accounts, contact lists and document creation.

“For the attacker, creating or using tools available to mimic logon pages can lessen the amount of work required, with cloud apps,” said Morris. “For example, phishing for [credentials] to a checking account could be restricted to solely clients of the focused financial institution, whereas, a cloud service, like Gmail would have many extra potential targets.”
Phishing and spear phishing within the cloud
What makes phishing and spear phishing a cloud infrastructure totally different is the kind of assault, in accordance with Patrick Harr, CEO at SlashNext.
“The attackers use compromised cloud infrastructure to improve success,” stated Harr. “You might see more malicious file attacks and targeted credential stealing focused on gaining more access to the organization.”
Phishing is all about getting credentials to entry areas of the community internet hosting delicate info. The entire thought behind phishing for cloud credentials or apps is to get a bigger payload.
“With a simple phish, an attacker is trying to get credentials to bank accounts, which will yield access to those accounts,” stated Morris. “With cloud services, the credentials that can be accessed could have far greater monetary value for ransomware or extortion.”
However, the easy phish within the cloud will nonetheless seem like a phishing assault as a result of it’s going after a generic viewers.
“Spear phishing will focus on a high-value target,” stated Morris, with “bait” specifically crafted and be extra plausible than a generic phishing try. “Spear phishing can also involve reconnaissance to gain intel about their target to make the phishing email/text/call very personalized.”
Spear phishing targets present extra worth to a risk actor as a result of the credentials and information are extra helpful. The upper the extent of the goal, the upper the extent of property concerned. If an attacker already has entry to some cloud purposes from an organization, it then turns into simpler to create phishing that mimics company communications. This makes it simpler to idiot the goal.
“Spear phishing uses social engineering tactics like personal information and executive and vendor impersonation to personalize attacks which makes these attacks more successful,” stated Harr.
Implementing safety coaching to boost consciousness of these kinds of assaults is essential. “Still, training is not a silver bullet because these attacks can be hard to spot,” Harr added, “so it’s also important to have security tools that can detect relationships and conduct contextual analysis to stop these attacks from entering the organization.”
Netskope’s report advisable utilizing cloud and SaaS safety administration packages to assist defend delicate information in cloud purposes from phishing assaults, and to recurrently use MFA or single sign-on instruments.
Bear in mind, an important job with regards to a spear phishing assault is to make use of zero belief and confirm something earlier than mechanically clicking on a hyperlink or sharing info.
