In the rapidly evolving world of cybersecurity, financial institutions find themselves in the crosshairs of increasingly sophisticated threat actors. Trustwave's 2024 Financial Services Risk Radar Report underscores this alarming trend, spotlighting insider threats and Phishing-as-a-Service (PaaS) as two of the most significant risks facing the sector this year.
The Rising Threat from Within: Insider Risks
Financial services organizations have long been vulnerable to cyber threats, but the 2024 report emphasizes that insider threats are on the rise. These are not your typical external hacking attempts. Instead, insiders—either malicious actors or negligent employees—are responsible for some of the most damaging breaches.
“Insider threats, often overlooked in organizations’ security postures, are the costliest form of data breach," says a Trustwave executive. These breaches can occur through unintentional actions, such as careless mistakes that lead to data exposure, or intentional acts motivated by financial gain or grievances against the company. Trustwave’s analysis reveals that 48% of the observed insider threats involved unauthorized use of remote access software, often allowing the perpetrator to bypass traditional security defenses.
Phishing-as-a-Service: The Cybercrime Marketplace
A major evolution in the cybercrime landscape is the mainstreaming of Phishing-as-a-Service (PaaS). This business model allows cybercriminals to lease ready-to-use phishing kits and services through underground platforms, making it easier for even less tech-savvy individuals to carry out sophisticated attacks. PaaS platforms include services that automate phishing campaigns, tricking victims into handing over sensitive financial information.
"Phishing is no longer the work of lone hackers sending mass emails; it’s a service you can buy with a subscription,” explains another executive. HTML attachments are the most common vehicle, bypassing traditional email filters by obfuscating malicious URLs.
Trustwave researchers have seen an increasing adoption of both HTML and PDF attachments as vectors for phishing attacks. These methods have proven effective in infiltrating even the most secure corporate networks, highlighting the pressing need for financial institutions to bolster email security and employee awareness.
Ransomware Continues to Dominate
While insider threats and phishing gain attention, ransomware remains a looming danger. Financial services organizations are prime targets for ransomware groups, with attackers often seeking to encrypt critical systems and extort large ransoms in cryptocurrency. Trustwave's analysis shows that the ransomware group AlphV now accounts for 24% of these attacks, with the financial sector making up a significant portion of their victims.
In a particularly concerning trend, these attacks are now more geographically concentrated, with 65% of ransomware breaches affecting U.S. organizations. Banks remain the top target, making up 20% of all ransomware incidents.
Emerging Tech Risks: Cryptocurrency and Deepfakes
As cryptocurrencies gain traction and deepfake technology becomes more sophisticated, new cybersecurity challenges are emerging. Cryptocurrency exchanges, where assets are traded and stored, are increasingly attractive targets for hackers. Meanwhile, deepfakes—videos or audio that convincingly imitate real individuals—are being used to manipulate financial transactions. Trustwave researchers documented a case earlier this year where a multinational firm lost $25 million to fraudsters using deepfake technology to impersonate the company's CFO during a video call.
Mitigation Strategies for Financial Institutions
The Trustwave 2024 report offers several recommendations for financial institutions looking to strengthen their defenses:
Continuous Monitoring: Implement continuous monitoring systems to detect unusual patterns in employee behavior and potential insider threats.
Advanced Training: Regularly update employee training programs to include the latest phishing tactics and prevention methods.
Layered Security: Use advanced email filters, machine learning models, and multi-factor authentication to protect against phishing and ransomware attacks.
Dark Web Monitoring: Financial institutions should also actively monitor the dark web for leaked data or insider recruitment efforts.
A Call to Action for Financial Services
With the stakes higher than ever, the Trustwave Risk Radar Report makes it clear: financial institutions must be proactive in addressing these emerging threats. Whether through insider threat mitigation, phishing defense, or ransomware resilience, staying one step ahead of cybercriminals will be crucial in the year ahead.
