Cyber threats: What trends are prevalent in 2025 and how to protect against them?

The world of cyber security is constantly changing, and cybercriminals are constantly developing new ways to attack companies and users. In 2025, cyber threats have become even more sophisticated and targeted, using artificial intelligence, cloud vulnerabilities and social engineering to break through security.

Companies and private users need to be aware of the latest attack methods and implement effective defense strategies to avoid falling prey to cybercriminals. In this article, we will discuss the latest trends in cyber threats, their effects and how to protect against them.

Key findings

• Cybercriminals are increasingly using artificial intelligence and deepfake to carry out phishing attacks and financial fraud.
• Ransomware attacks are evolving, and hackers are using double and triple extortion.
• Cloud threats are on the rise – companies need to focus on better securing data in the cloud.
• IoT (Internet of Things) is increasingly the target of attacks, as many devices still lack adequate security features.
• Zero Trust and network segmentation are among the best defense strategies in 2025.
• RamsData offers state-of-the-art IT protection solutions tailored to rapidly changing threats.

The biggest cyber threats in 2025

Cyber security experts indicate that in 2025, the biggest threats are:

• Ransomware 3.0 – cybercriminals use double and triple extortion (data theft + blackmail + selling information on the black market).
• AI-driven ph ishing – advanced phishing attacks using AI to generate fake news and deepfakes.
• Cloud attacks – bad configurations in SaaS services lead to data leaks.
• IoT software vulnerabilities – un-updated devices are easy targets for hackers.

Ransomware – how is the attack strategy changing?

Ransomware attacks are evolving and becoming more complex. Today, cybercriminals are using so-called ransomware-as-a-service (RaaS), offering ready-made attack tools to anyone who pays.

The new ransomware methods are:

• Double extortion – encryption of data + theft and threat of disclosure online.
• Triple extortion – additional attacks on the company’s customers whose data was stolen.
• Attacks on backups – Hackers first delete backups so that the company cannot recover data.

How do you protect yourself?

• Use anti-ransomware systems such as. Opswat MetaDefender.
• Create multi-step backups and store them offline.
• Implement network segmentation to limit the spread of the virus.

Phishing and deepfake – new fraud techniques

Phishing is still one of the most common threats, but in 2025 it is more advanced than ever. Hackers are using AI to generate authentic-looking emails and voice messages, as well as deepfake to fool employees and managers.

The most common phishing techniques in 2025:

• Business Email Compromise (BEC) – impersonating a company director and soliciting employees to transfer money.
• Voice phishing (vishing) – the use of deepfake to imitate the voice of a company’s CEO and transmit false instructions.
• MFA fatigue attack – flooding users with fake login approval requests until they finally click “yes.”

How do you protect yourself?

• Implement advanced email protection.
• Train employees on phishing recognition.
• Use multi-factor authentication (MFA) with physical security keys.

Cloud under fire – threats to companies using SaaS

More and more companies are moving their data to the cloud, but improper configuration of SaaS services can lead to data leaks. The most common cloud security mistakes are:

• No file access control.
• Unsecured APIs.
• No encryption of stored data.

How do you protect yourself?

• Apply the principle of least privilege (Least Privilege Access).
• Monitor user activity in the cloud.
• Take advantage of cloud security tools, such as Palo Alto Networks.

Best strategies to protect against cyber threats

1. Zero Trust Security – assumes that no one is trustworthy until they are verified.
2. Regular updates and security patch management.
3. Network segmentation and DDoS protection.
4. Automatic real-time threat analysis.

Frequently asked questions

What are the biggest cyber threats in 2025?

The biggest threats are ransomware, phishing with AI, attacks on the cloud and IoT devices.

What technologies help protect against cyber attacks?

NGFW (Next-Generation Firewall) systems, Opswat MetaDefender tools and Zero Trust strategies are worth implementing.

Can companies prevent all cyber attacks?

No, but the use of good cyber security practices and modern technology significantly reduces the risk of attacks.
