The annual ThreatLabz Report reveals phishing-as-a-service as the key source of attacks across critical industries and consumers globally.
April 20, 2022 - Zscaler, Inc., the leader in cloud security, today released the findings of its 2022 ThreatLabz Phishing Report that reviews 12 months of global phishing data from the Zscaler security cloud to identify key trends, industries and geographies at risk and emerging tactics.
According to the FBI Internet Crime Complaint Center (IC3), phishing attempts are the most frequently-reported cyberattack. Zscaler’s ThreatLabz research team analyzed data from more than 200 billion daily transactions, and 150 million daily blocked attacks in order to identify emerging threats and track malicious actors from across the globe. This year’s report showed dramatic 29% growth in overall phishing attacks compared to previous years, with retail and wholesale companies bearing the brunt of the increase. The report also showed an emerging reliance on phishing-as-a-service methods, as well as new attack vectors, such as SMS phishing, becoming one of the more prevalent methods of intrusion.
“Phishing attacks are hitting businesses and consumers with an alarming frequency, complexity, and scope. Our annual Phishing report highlights exactly how cybercriminals are using this prevalent attack vector as a starting point as they attempt to breach organizations around the globe,” said Deepen Desai, CISO and VP of Security Research and Operations at Zscaler. “To defend against these modern phishing attacks, businesses should consider a cloud-native zero trust security platform like Zscaler. The Zscaler Zero Trust Exchange delivers multi-pronged phishing defenses with full SSL inspection including AI/ML-powered detection, IPS signatures to detect phishing kits, and proactive controls to block high risk destinations such as newly registered and newly observed domains that are often abused by threat actors to launch phishing attacks.”
Phishing has always been one of the most pervasive cyberthreats, with various methods used to steal private information. One of the reasons this type of attack grows in prevalence every year is its low barrier to entry. Cybercriminals use current events, such as the COVID-19 pandemic or cryptocurrency, to convince unwitting victims to hand over confidential data, such as passwords, credit card information, and login credentials.
The 2022 ThreatLabz Phishing Report found that phishing attacks lure victims by posing as top brands or promoting topical events. The top phishing themes in 2021 included categories such as productivity tools, illegal streaming sites, shopping sites, social media platforms, financial institutions, and logistical services.
A global problem
In 2021, the U.S. was the most-targeted country globally, accounting for over 60% of all phishing attacks blocked by the Zscaler security cloud. The next most frequently attacked countries include Singapore, Germany, the Netherlands, and the United Kingdom.
Not all countries experienced the same attention from phishing attacks. For example, the Netherlands experienced a decrease of 38 %, which may have resulted from recently-passed legislation that increased the penalties for online fraud.
Phishing attacks were also not evenly distributed across different industries. Retail and wholesale businesses experienced an increase of over 400% in phishing attempts - the most out of all tracked industries. These businesses were followed by financial and government sectors, with organizations in these industries seeing over 100% increases in attacks on average. However, some industries experienced partial relief from phishing attacks last year. Healthcare saw a notable drop of 59 %, while the services industry saw a decline of 33 %.
Phishing-as-a-service: The growing threat
While phishing has long been one of the most common tactics used in cyberattacks by sophisticated threat actors, it's becoming more accessible to non-technical cybercriminals due to a maturing underground marketplace for attack frameworks and services. By selling their pre-built phishing tools and services on the dark web, cybercriminals are making it easier to deploy phishing scams at scale, creating a greater chance for more phishing activity in 2022.
This outsourcing of services, known as Phishing-as-a-Service, provides easy access to two of the most popular attack offerings: phishing kits and open-source phishing frameworks. While these have some overlapping functionality, combining the two allows criminals to wage powerful attacks very quickly. The 2022 ThreatLabz Phishing Report outlines the value of these two offerings and how
- Phishing kits: According to the ThreatLabz research team, phishing kits package up and commoditize everything required to quickly launch hundreds or thousands of convincing and effective phishing pages using pre-built templates. Phishing Kits help attackers quickly create an online infrastructure that provides the thin veneer of legitimacy required to convince their victims to hand over private information.
- Open-source phishing frameworks: Open-source frameworks are an alternative to phishing kits often found on code sharing forums like StackOverflow and GitHub. These frameworks have various features that can automate parts of a phishing attack or even the entire process. As these frameworks are open source and free, they are a popular option for phishing actors of all sizes.
Countering phishing attacks
According to the Zscaler ThreatLabz research team, an average-sized organization receives dozens of phishing emails every day. This means that employees at all levels must be aware of the most common phishing tactics and empowered to spot phishing attempts that can result in financial losses and damage to the business’ brand.
Facing the threats outlined in the 2022 ThreatLabz Phishing Report can be daunting, and while it's impossible to eliminate phishing risk, effective management can prevent business-critical information from falling into the hands of cybercriminals. Among other recommendations, Zscaler suggests the following tactics for countering phishing growth:
- Learning and understanding the risks posed by phishing to better inform policy and technology decisions
- Leveraging automated tools and actionable intelligence to empower employees with the tools needed to reduce phishing incidents
- Delivering timely employee training to build security awareness and promote user reporting
- Simulating phishing attacks to identify gaps in security policies and procedures
- Evaluating security infrastructure to ensure access to the latest research and system capabilities
How the Zscaler zero trust exchange can mitigate phishing attacks
User compromise is one of the most difficult security challenges to defend against. The Zscaler Zero Trust Exchange incorporates phishing prevention controls into a holistic zero trust architecture that disrupts every stage of attacks and minimizes damages. Capabilities include:
- Preventing compromise with full SSL inspection at scale, threat analysis using natively integrated threat intel including IPS signatures of phishing kits, AI/ML-powered heuristic detection of novel phishing sites, and policy-defined high-risk URL categories commonly used for phishing such as newly observed and newly activated domains.
- Eliminating lateral movement by connecting users directly to apps, not the network, to limit the blast radius of a potential incident.
- Shutting down compromised users and insider threats with in-line application inspection and integrated deception capabilities to trick and detect attackers.
- Stopping data loss by inspecting data both in motion and at rest to prevent theft by an active attacker.
The ThreatLabz team evaluated data from the Zscaler security cloud, which monitors over 200 billion transactions daily across the globe. ThreatLabz analyzed a year’s worth of global phishing data from the Zscaler cloud from January 2021 through December 2021 to identify key trends, industries and geographies at risk, and emerging tactics.
