For years, we’ve been writing about the risk that cybersecurity threats present to businesses. Cybercrime is on the rise, and businesses stand to lose more than individuals do. In this article, we’ll examine the key cybersecurity threats businesses will face in 2025, and how to combat them.
Cybersecurity threats: 2024 in retrospect
A number of high-profile cybersecurity incidents indicated a growing trend of targeted attacks. In January, a Russian state-sponsored hacker group known as Midnight Blizzard(neues Fenster) breached Microsoft’s corporate systems. In the aftermath, it emerged that the group was attempting to log into US federal agency cloud accounts to steal sensitive data.
In another incident, more than 2.7 billion Americans may have had personal data leaked by a data breach affecting National Public Data(neues Fenster), a background check company. The data includes names, addresses, dates of birth, Social Security numbers and phone numbers. A hacker group known as USDoD claimed to be selling the information, which included data from the US, the UK, and Canada. While not all of the information was found to be accurate, the warning is stark: Cybercriminals are attempting to acquire personal data to sell, most likely to data brokers. These attacks signal an increase of targeted attacks on personal data through business infrastructure.
Not only corporations and governments are being targeted: 2,825 businesses of all sizes in the US reported to the Internet Crime Complaint Center that they were affected by ransomware alone in 2024(neues Fenster), a 22% increase from 2022. Small businesses are less likely to be able to recover from the impacts of a cybersecurity threat due to the resources they have access to. 89% of small businesses surveyed by KPMG(neues Fenster) that have been affected by a cyber breach reported that it impacted their reputation, with a further 93% reporting that their ability to operate was impacted.
What does an increase in cybersecurity threats mean?
Businesses that have been impacted by a cybersecurity threat risk their reputation, as well as their financial security and may face legal consequences.
Many countries, including the US(neues Fenster) and Australia(neues Fenster), are introducing more stringent cybersecurity regulations for businesses. In the UK, GDPR requires that businesses protect personal data with adequate technical safeguards, such as encryption. The onus will be on businesses to prove they’re storing data securely, regularly assessing risk to their infrastructure, and actively creating an incident response plan.
According to new research from Fastly(neues Fenster), businesses affected by cybersecurity incidents take an average of 7.3 months to recover. This is “25% longer than expected and over a month past the anticipated timeline of 5.9 months.” This might not be a survivable period of time for a small business, taking into account the financial losses and potential legal ramifications of a cybersecurity incident.
Looking ahead to 2025
If you aren’t aware of the most prevalent risks on the business landscape right now, don’t worry. Here are the four most common cybersecurity threats and how you can prevent falling prey to them.
Weak passwords
A weak password is a cybersecurity threat that occurs within your business infrastructure, rather than from outside of it. Employees using weak passwords, or reusing the same passwords, presents cybercriminals with the opportunity to easily gain access to multiple accounts using a dictionary attack.
Weak passwords expose your business to many risks including data breaches. A data breach can greatly impact trust in a business, as they’re often caused by a lack of adequate defence. Between 2022 and 2023, AT&T(neues Fenster) was made aware of a data breach affecting 10m of its customers. The cybercriminals were able to access the business’s cloud data storage platform Snowflake thanks to a lack of enforced strong password requirements and multi-factor authentication (MFA) within AT&T.
MFA, or two-factor authentication (2FA) as it’s also known, is an excellent mechanism to prevent unauthorized access to the tools your employees use. 2FA ensures that an employee verifies their identity using an additional method beyond a traditional password, such as a fingerprint or a code generated from an authentication app. Enforcing 2FA for all employees is one of the best passive ways to improve your business’s cybersecurity.
Phishing
Phishing is a tactic scammers use to trick people into sharing logins to their online accounts. For example, a scammer might contact you via email posing as Amazon customer service to tell you that your account has been frozen. In order to verify your identity and unlock your account, they might ask you to share your date of birth, credit card number, or account password.
If you share that information, they’ll be able to use it to access your accounts. This could mean impersonating you to your bank and withdrawing money or making large purchases online. Once the money is gone, it’s unlikely you’ll be able to reclaim it.
Phishing within a business is even more dangerous, as the financial risks are much higher. If an employee uses a weak password which is then phished by a scammer, the scammer could only potentially gain access to one platform as opposed to multiple platforms if that password has been reused. The scammer can then access your work infrastructure because of the weak personal password of one employee.
Enforce a strong password policy within your business to minimize the risk and impact of phishing. This means creating a different password for each platform.Helping employees manage multiple passwords means using a secure password manager, a tool that helps them generate, store, and autofill their passwords securely.
Ransomware
Ransomware is the weapon of choice for cyber extortionists: It’s a form of malware(neues Fenster) that encrypts the data stored on your computer, and demands a payment in return for regaining access.
Some ransomware attacks have become infamous. Change Health(neues Fenster), a health tech company owned by UnitedHealth, was affected by a high-profile ransomware attack in February 2024. Records of more than 100 million people were exposed, making it one of the largest data breaches in history. The hackers collected personal, financial, and other sensitive information and demanded (and ultimately were paid) $22 million. It isn’t clear if the data was ever deleted, meaning it still could have ended up on the dark web.
Preventing ransomware means putting a strong defense system in place. Performing regular data backups can ensure you have access to data even if you lose access to one of your systems. Monitoring your network traffic and your employee logins for unusual activity can also help you identify an intruder in your network before they’re able to cause any harm.
