Cyber criminals set their sights on accountancy firms – 7 steps to minimise risk

Accountancy practices are facing an increase in cyber risks as criminals switch their focus to ‘softer target’ smaller firms. Joe Collinwood, CEO at CySure explains why accountancy firms are targets for hackers and what steps they can take to minimize their exposure

Cyber criminals set their sights on accountancy firms – 7 steps to minimise risk

When it comes to cyber crime, small accountancy practices are not exempt from the disruption that affects large organisations. Their size can make them more vulnerable as they are perceived as a softer target. In the USA for example, there has been an explosion in fraudulent W-2 filings and in the UK with more filings now online, risk is increasing. So why are accountants being targeted?

  • They hold large amounts of private data
  • They have the information cyber criminals want – corporate financial data, social security numbers, Tax IDs, bank accounts, payroll data, identification data for validation and reporting purposes
  • Accounting firms use similar software, so if a criminal finds a vulnerability that can be exploited they have lots of potential victims
  • Typically there is inadequate technical protection, policies and procedures and that leaves firms wide open to a cyber attack
  • A lack of incident response and business continuity procedures means accountants are more likely to pay a cyber criminal money because they fear they may not be able to recover from an attack and the firm’s reputation will be tarnished.

Many accountancy firms are making it easier for hackers by underestimating the threat they face from cyber attacks. There were 438 separate data security incidents reported to the Information Commissioner’s Office (ICO) in Q2 2018/2019 alone in the finance, insurance and credit sector. The cost to launch cyber attacks is negligible and the most likely method of breach is phishing i.e. human error.

Gateway to Information

Self-employed accountants and accountancy practices are on the radar of cyber criminals because of the amount of valuable data they hold on their clients. This information enables hackers to pull off complex frauds at a later date. The more information they have, the better a picture they can build of the small business or person whose bank account they intend to target.

Cyber criminals view accountancy firms as a “gateway” to client information and are perceived as a soft target with few security barriers, limited cyber security tools and little or no in-house expertise. Additionally, as many firms use the same software systems, hackers are motivated to seek vulnerabilities in the software knowing there will be a substantial pay day by exploiting the weakness to attack multiple businesses.

Small but not safe

According to the Cyber Security Breaches Survey 2018, 42% of small businesses identified at least one breach or attack in the last 12 months. Depending on the severity of the attack, SMEs can suffer more disruption than their larger counterparts as they lack the processes and cyber expertise to deal with the ramifications of an attack. The impact to business operations and the inability for staff to carry out their day to day work can have longer term consequences, not only for an accountancy practice itself but also for its clients.

Minimise Risk – 7 simple steps to cyber resilience

No business is too small to be attacked. However with the right approach to security, no business is too small to protect itself. Accountancy firms can pave the way to cyber resilience by following these top cyber-security tips:

  • Invest in effective firewalls, anti-virus and anti-malware solutions and ensure any updates and patches are applied regularly, ensuring that criminals cannot exploit old faults or systems
  • Ensure business critical data, such as customer data and financial information, on all company assets is securely backed up and can be restored at speed
  • Have simple, clear policies in place to create a cyber-conscious culture in the workplace and ensure it is communicated to all personnel so they are familiar with it
  • Have regular awareness training so that employees are constantly reminded of potential scams or tactics that can be used to trick them
  • Review contracts and policies with suppliers to ensure they have an accredited standard for cyber-security for themselves and their partners to protect the supply chain
  • Have an up-to-date incident response plan that is practised regularly so that employees know what to do when they suspect there is an attempted breach or if an actual incident occurs
  • Consider investing in cyber insurance to cover the exposure of data privacy and security.  Accountancy firms should research insurance policies carefully to understand the level of coverage offered and their responsibilities to stay within the conditions of the policy.

Where to start and what to do now

Cyber security need not be complex or prohibitively expensive. In the UK Cyber Essentials (CE) is a government and industry-backed scheme specifically designed to help organisations protect themselves against common cyber-attacks. In collaboration with Information Assurance for Small and Medium Enterprises (IAMSE) they have set out basic technical controls for organisations to use which is annually assessed.

By using an online information security management system (ISMS) that incorporates Cyber Essentials and NIST, accountancy firms can undertake a certification route guided by a virtual online security officer (VOSO) as part of their wider cyber security measures. This will help the organisation to coordinate all security practices in one place, consistently and cost-effectively. Additionally, firms can take advantage of the expertise of online cyber security consultants at a fraction of the cost of a full-time in-house security specialist.
