Top 7 Cyber Security Threats To Financial Services

 

June 27, 2018 by Siobhan Climer

The 2017 Equifax data breach exposed over 143 million American’s personal information. In 2013, over 3 billion Yahoo accounts were compromised. Over the past decade, major data breaches have affected over 1 trillion user accounts, with those numbers expected to rise. The financial impact of this is huge, as we recently reported.

Despite every attempt to remain secure, financial services make up 35% of all data breaches, earning it the unfortunate title of the most-breached sector. These events remind both business leaders and consumers of the tenuous nature of cyber security. Are you prepared to face these top cyber security threats to financial services?

Top Cyber Security Threats To Financial Services

 

1.    Web Application Attacks

 

The Attack: From Google docs to calculator tools, webmail platforms to financial records, most of the applications we use today are hosted on the web. These applications are vulnerable to attacks because they are the most accessible and rely on user input. Applications need to be accessed over Port 80 (HTTP) or Port 443 (HTTPS) to function. The types of web application attacks vary from unvalidated redirects and forwards to SQL injections. DDoS attacks, which we’ll go over in a minute, can fall into this category as well.

The Defense: Use an intelligent Web Application Firewall (WAF) along with the behavioral firewall to block cross-site scripting (XSS) attacks. Auditing your databases regularly is essential to identify and deal with any vulnerabilities before they are exploited. Simple steps, like clearing stored cookies, avoiding untrustworthy websites, and scanning for viruses and malware are just as important as brushing your teeth and flossing when it comes to cyber security health.

 

2.    DDoS Attacks

These attacks go a long way to silencing websites that the hackers may disagree with, or disrupting business flow to a competitor. DDoS attacks can be inexpensive ($150 buys a week-long DDoS attack on the darknet), and, therefore, prolific. 1/3 of network downtime incidents are attributed to DDoS attacks, costing businesses financial losses and reputation damages.

The Defense: Luckily, there are lots of DDoS protection tools and integrated preventative services. Cisco produced a helpful guide outlining the different DDoS methodologies and prevention steps, which is perfect for a longer read. In brief, remotely triggered black hole (RTBH) filtering is a good option for preventing attack traffic before it hits the network. Anycast, a routing methodology that routes traffic through various nodes, can dilute malicious traffic from DDoS attacks. Other tools, like reputation-based blocking, can identify malicious URLs and establish a database to protect against future attacks – like adding spam callers to a blocked senders list.

 

3.    Backdoors And Supply-Chain Attacks

By using backdoors, hackers gain access to the network while bypassing intrusion detection systems. Port binding, connect-back techniques, connection availability abuse, legitimate platform abuse, common service protocols, and custom DNS lookups are all examples of backdoor attacks.

Cyber security threats to financial services are rising, including a recent threat to a financial institution that began seeing suspicious DNS requests while processing financial transactions. This led to the discovery of ShadowPad, one of the largest supply-chain attacks that originated in legitimate software. Somewhere along the line, someone opened a backdoor, opening up hundreds of customers to serious cyber security threats.

The Defense: Auditing and monitoring are the surest ways to detect supply-chain attacks. In the case of ShadowPad, it was the observation by the monitoring services of the financial institution that first alerted IT to the unusual activity. Firewalls can help, but they won’t prevent access from legitimate requests, even if something malicious is buried inside. Bringing in a trusted partner that manages and monitors your services is one way to ensure you have eyes on your network 24/7/365.

 

4.    Third-Fourth-Fifth Party Vendors

 

The Attack: As CTO Jason Wankovsky recently discussed in a CAMP IT Mindsight panel discussion, managing risk of third-, fourth-, and fifth-party vendors is a challenge. Though you may have strong protections in place in your own network, when you begin working with other vendors, you must also assess the cyber security threats to financial services of third-party agreements. If your partner is attacked by ransomware, how will that affect your bottom line? Will you be at risk, too? Who is responsible for protecting the network?

The Defense: Contracts and reviews. You aren’t in control of your third-party vendors, but you get to decide if they should remain your partner. Whether it is a cloud provider or a mobile app developer, ensure any vendors you work with have strong security measures in place. Then, make sure any other parties they work with also have secure networks. It can be a convoluted network, but assessing and developing a risk management plan is necessary to protect yourself from these unknowns.

5.    Global Operational Risks

 

The Attack: Globalization means that businesses operate internationally, across state lines, in different towns with different languages, regulations, and expectations. This increase in operational size means an increase in operational risk. Cyber security threats to financial services are especially vulnerable, since cyber criminals target the financial sector in the hopes of larger monetary gains.

The Defense: Assessment. Ask yourself the following:

  • Where are my third- and fourth-party vendors located?
  • What regulations are affecting my business and those of my third-party vendors?
  • Are security risks to my business different in different locations? How so?
  • What security measures do we need in these different regions?
  • Are we expanding? Will our cyber security risks expand as well?

Then, determine if your team has the resources necessary to ensure the protection of consumer data. If they don’t, who can you entrust with the responsibility of securing your environment? Finding a trusted managed services provider might be the next step.

 

6.    Emerging Technologies

 

The Attack: It’s cliché to say it at this point, but technology is always changing. Emerging technologies are useful, necessary, and provide competitive advantages to your institution. In the finance sector, CIOs and CTOs are already considering how blockchain and the Internet of Things (IoT) can be leveraged to build growth. But these tools also bring additional risks. You can be confident hackers are ahead of you, finding ways to utilize blockchain and IoT for attacks. Just last year, the largest DDoS attack came via IoT.

The Defense: The risk will never be fully diminished, but there are ways to defend yourself. Regulations are trying to keep pace, including a new measure that requires companies to meet minimum cyber security requirements. In the end, though, financial institutions are responsible for protecting their institution from DDoS attacks by using multi-factor authentication internally and enabling device patching to address different vulnerabilities.

7.    Insider Threats

 

The Attack: Unfortunately, the reality is that 60% of cyberattacks come from inside the company. Financial firms and financial services were in the top three sectors targeted by insider attacks, according to that same IBM report. From disgruntled employees to poorly-compensated bank tellers, 75% of those internal attacks were intentional. These employees can offer up their credentials to a hacker, or simply decline to seriously review cyber security concerns due to poor morale. This makes the employee one of the top cyber security threats to financial services.

The remaining 25% of internal attacks are due to human error. Phishing scams and malware downloads can work on even the most loyal and hard-working employees.

The Defense: Protect what is most valuable, tighten access controls, and ensure your employees are satisfied and feel valued for their contributions. A strong organization that protects and rewards employees means your first layer of defense – the people you employ – are ready to make sure institutional assets are safe.
