Data Breaches Aren’t Uncommon
It’s not just small companies with limited security budgets that have exploitable cyber gaps. Often, in fact, large organizations become targets because of the amount and nature of the data that they hold. Organizations in the healthcare sector, for example, have proven time and again to be a popular targets for cybercriminals.
Another example of a large organization being targeted is Experian. Experian experienced a major data breach in August 2020 where over 24 million records were exposed. The attackers impersonated a client and were able to request and obtain confidential data. Experian claimed that no customer banking information was exposed. Even so, personal information like this could be used in a targeted social engineering strategy to then get Experian customers to reveal further sensitive information such as their banking details.
This isn’t the first major data breach that Experian has had. Back in 2015, 15 million North American customers and applicants had their personal data, including Social Security numbers and ID details, stolen. Perhaps because of this prior experience, Experian understands the risks and are adept at dealing with cyber breaches. They claim that the attacker’s hardware has already been seized and the collected data secured and deleted.
How Much Does the Average Data Breach Cost?
The answer to this question varies between country and is additionally dependent on the sector but in general, can span anywhere from $1.25 million to $8.19 million.
According to the 2020 report from IBM and the Ponemon Institute the average cost of a data breach in 2020 is down 1.5% since 2019 and cost around $3.58 million USD. This works out to be around $150 per record and is a 10% rise over the last 5 years. The report analyzes recent breaches at more than 500 organizations to spot trends and developments in security risks and best practices.
The cost estimate includes a combination of direct and indirect costs related to time and effort in dealing with a breach, lost opportunities such as customer churn as a result of bad publicity, and regulatory fines. Though the average cost of a breach is relatively unchanged, IBM says the costs are getting smaller for prepared companies and much larger for those that don’t take any precautions.
Interestingly, various industries including healthcare appear to be more susceptible targets for attackers. According to the report, healthcare breaches cost organizations $6.45 million per breach, a number that eclipses all other sectors and makes it the ninth year in a row that healthcare organizations have had the highest costs associated with a data breach.
The average cost for per breached healthcare record ($429) is more than double any other industry too and substantially higher than the average, $150, according to the report. Healthcare breaches can often take the longest to identify (up to 236 days) as well.
Data Breaches are Happening all the Time
Data breaches are occurring constantly. Records from large brands with big security budgets and teams as well as much smaller organizations. It’s important that everyone understand the importance of secure digital practices and explores strategies for educating staff to reduce the risk of social engineering tactics.
How do Data Breaches Occur?
Hackers use various strategies to gain access to data. For example, with Experian the attacker leveraged human weakness through social engineering to persuade an employee to give them the data. Other strategies could be exploiting weaknesses such as a misconfigured or unsecured cloud storage. Alternatively a data breach could be the result of a malicious malware or ransomware.
According to the IBM/Ponemon report around 40% of all incidents were actually due to either cloud misconfigurations or stolen login details. Because of this IBM has urged companies to reexamine their authentication protocol to ensure 2FA is active.
A final note on the ascertaining of data by attackers is around state-sponsored attacks. State-sponsored attacks only make up around 13% of the overall number of attacks according to the report. However, with an average associated cost of around $4.43 million it’s clear that these types of attacks tend to target high-value data and this results in a more extensive compromise of victims' environments.
The energy sector, commonly targeted by nation-states, saw a 14% increase in breach costs when compared to the prior-year period, with an average breach cost of $6.39 million.
How can Organisations Reduce the Cost of Data Breaches?
“The average time to identify and contain a data breach, or the "breach lifecycle," was 280 days in 2020. Speed of containment can significantly impact breach costs, which can linger for years after the incident.” - Source
By having mitigation measures in place IBM/Ponemon estimate companies can reduce the cost of a breach by an average of $720,000.
According to their report those companies which had automated technologies deployed experienced around half the cost of a breach ($2.65 million on average) compared to those that did not have these technologies deployed ($5.16 million average).
Security response times were also reported to be ‘significantly shorter’ for companies with fully deployed security automation – these companies are as much as 27% faster than their counterparts at responding to breaches.
Security tools like OSINT platforms not only enable a faster breach response but a significantly more cost-efficient one as well, which as the security professional shortage persists is of absolute importance.
Final Thoughts
With our increasing levels of digitisation, our growing reliance on the cloud, and the complexity of security systems paired with human error there are more attack vectors than ever before for hackers to exploit.
A data breach could involve anything from publicly available data being scraped and sold off to spammers, to online banking and credit card information being stolen. The longer a data breach goes undetected the longer the threat actors have to utilize this data causing more harm as time goes on.
Having the right tools and processes in place will allow you to detect data breaches early or even prevent a data breach from happening in the first place. With the steadily rising cost associated with data breaches, this could save an organization millions in the long run.
