Cyber criminals are evolving, crafting new and sophisticated attack vectors to launch cyber attacks on accounting firms. Accounting firm hacks primarily occur due to the sensitive and valuable personal identifiable information (PII) and financial data that accounting firms possess, including:
It's no brainer that hackers target this kind of data as they are goldmines for identity theft and fraud. For instance, the accounting firm Deloitte suffered a cyber attack in 2017 where hackers infiltrated Deloitte’s cloud email server, giving them privileged access to 5 million client emails. The hackers extracted vital client data from the email database including usernames, passwords, business plans, and health information.
Deloitte serves top clientele like US government agencies, multinational companies, big banks, and media companies. Deloitte alerted its six largest clients about the hack. Damages of this magnitude due to an accounting firm cyber-attack induce reputational costs to the business, causing mass client exodus, and business shutdown in worst cases.
If you want a victim to pay the ransom, you need leverage. Hackers know that Accounting firms depend on the trust of their clients. If you find out your Accountant has been hacked, would you trust them with your money? Even better, Accounting firms process most of their business during tax season. Take an Accountant offline with ransomware or email hijacking during tax season and they will pay the ransom or face oblivion.
Accounting firm hacks result in unwanted access to sensitive client data that threat actors capture to engage in identity theft and fraud. Accounting firms must therefore take proactive steps to detect, protect, and remediate. Check out our Top 4 steps to tell if your Accounting firm has been hacked:
Now, let’s dive into these essential steps to detect hacked Accounting firms and how to protect your Accounting firm:
Hacking a single Accounting firm employee’s email jeopardizes its entire system. Hackers are aware of this fact and hunt for the weakest link in the chain. It's not good enough to train your IT team and Senior Accountants on password hygiene. Hackers target the weakest sheep in the heard gearing and employ the shotgun approach by purchasing mass password lists and trying them, 24/7, on all of your accounts. Successfully finding an email/password combo can give hackers access to the accounting software of the entire hacked Accounting firm. The hackers then steal, alter, or delete the records on the software. If the hackers are feeling enterprising, they can ransom the account access or the data back to the Accounting firm knowing that the cost of their integrity, confidentiality, and availability is worth a lot of money to the firm!
Hacked Accounting firms can leverage free tools like Iceberg Cyber’s online Password Check tool to detect system compromise by an external actor. The tool only requires the Accounting firm to key in their emails. The tool then scans the internet for any trace of their passwords before giving feedback to the Accounting firm to initiate remediating actions if a breached account has been detected.
Iceberg Cyber also offers this tool to its premium users as part of the Cyber Brief subscription, priced at $200/month. In so doing, Cyber Briefs save you from the hassle of periodically checking for compromised emails and passwords by offering a 24-hour monitoring solution that gives real-time threat alerts.
IT departments can employ Intrusion Detection Systems (IDS) and Security Information and Event Management (SIEM) solutions to thwart cyber- attacks on accounting firms .These solutions scan through logs and intercept network traffic to detect potential security threats. An example of a SIEM solution that combs through event logs to detect any network anomalies is the Microsoft Azure Sentinel.
A firewall intercepts all traffic passing through the network and filters out traffic from malicious sites and potential actors. As such, firewalls prevent unauthorized access to the Accounting firms’ online books and cloud systems.
Accounting firms can also use firewall logs to identify the nature of threats, threat actors and their attack methods. Such moves enables an Accounting firm to be proactive in its cybersecurity approach.
