Cyberattacks can damage your reputation, cost you millions and halt productivity. Protecting against threats requires proactive monitoring, employee training and adopting zero-trust security models.
Adversaries are getting more aggressive and finding new ways to attack organizations. This article explores the top cybersecurity threats to watch in 2025, including ransomware, APTs, supply chain attacks and IoT vulnerabilities.
1. Ransomware
Cybercriminals are increasingly using ransomware to extort victims, threatening to release proprietary data or attack critical systems. Attackers gain a foothold by exploiting vulnerabilities or leveraging phishing, brute-forcing poorly-configured services, and tools such as Mimikatz that harvest credentials for privilege escalation. Once attackers are inside, they use tools to move laterally.
Increasingly, attackers target critical infrastructure such as power grids and water supplies or IoT devices integrated into those systems. These attacks can cause widespread disruption and even loss of life. Attacks on hospitals can jeopardise patient care, while attacks on energy systems can lead to prolonged blackouts.
Attackers also leverage ransomware to extort victims of all kinds by encrypting their data and demanding payments in cryptocurrency. Moreover, attackers often follow up with distributed denial of service (DDoS) attacks to put additional pressure on victims.
Organizations must adopt a multi-layered approach to defence. This includes utilising generative AI to improve social engineering techniques, such as voice phishing. This enables threat actors to mimic authentic voices in local accents and dialects, making them harder to spot.
2. Advanced Persistent Threats (APTs)
APTs are high-complexity cyberattacks typically orchestrated by sophisticated state-sponsored groups or cybercriminals. They use a combination of methods to gain unauthorized access and remain undetected for extended periods, often with the goal of data theft or espionage.
Attackers steal sensitive information by stealing passwords or exploiting unpatched vulnerabilities in software and hardware. They can also infiltrate networks through social engineering and physical intrusions. Once inside a network, APTs can remain undetected for long periods of time and steal data over a period of weeks or months. This differs from the rapid hit-and-run approach of ransomware attacks and Distributed Denial of Service (DDoS) attacks.
APTs are dangerous because they can target any industry that relies on a network for communication, control and storage. This includes banks, hospitals and critical infrastructure operators. The attackers can sell stolen identities and extort money or disrupt operations by stealing valuable IP or shutting down critical systems. They may even plant malware in the supply chain to gain a foothold and attack at scale.
This type of attack can be difficult to detect and require a multi-layered defense strategy that combines threat protection, incident response and threat intelligence.
3. Supply Chain Attacks
Supply chain attacks exploit the interconnected systems of organizations by targeting third parties and vendors. Attackers gain access by breaching one supplier, which allows them to penetrate multiple customers simultaneously using a technique known as “island hopping.” This threat has gained in importance because it is more lucrative than attacking directly.
The attacks are conducted through a variety of techniques and include malware, ransomware, Distributed Denial of Service (DDoS) attacks, man-in-the-middle attacks and more. Ultimately, they expose critical data and cause monetary loss.
Zero-day exploits and advanced persistent threats (APTs) have fueled the recent surge in supply chain attacks. Examples of this include the NotPetya malware outbreak and the 2023 Magecart supply chain attack that compromised more than 130 organizations worldwide, including British Airways, Atlassian and Zellis.
Infostealer malware is a common element of these attacks and enables attackers to steal sensitive data and execute malicious actions. Additionally, attackers can tamper with hardware or software by injecting rogue code into manufacturing processes or by installing it in end-user devices during the distribution process. This may result in a disruption in operations or outages of an organization’s services.
4. IoT Vulnerabilities
IoT vulnerabilities present a significant risk to our digital and physical safety. IoT devices have access to sensitive information about our daily activities and habits, as well as physical infrastructure such as homes, offices, and vehicles. This makes IoT security a top priority for organizations that want to protect their data and customers.
Cybercriminals can exploit IoT sensors in a variety of ways to carry out attacks. Some examples include stealing personal information (such as medical records, power consumption, and driving behavior), using compromised devices to conduct distributed denial-of-service attacks, and crypto-mining.
IoT devices often use outdated operating systems that contain known vulnerabilities, which make them easy targets for attackers. Moreover, IoT sensors don’t have the robust security controls of IT systems like workstations and servers, which also increases their vulnerability.
The Ring home security camera hack and Mirai botnet attack are just a few examples of how IoT vulnerabilities can lead to severe consequences. IoT vulnerabilities also make it easier for threat actors to exploit other connected devices in a network. They can spread ransomware, propagate phishing attacks, and even launch more sophisticated attack tactics.
5. AI-Powered Phishing
Artificial intelligence is becoming a more prominent threat vector for attackers, allowing them to automate attacks, craft sophisticated malware, and evade detection methods. This “AI arms race” will elevate the impact of attacks while also requiring new strategies from defenders to mitigate risk.
For example, AI-powered phishing attacks are increasingly personalized and realistic to impersonate trusted individuals. These phishing schemes can target individuals and organizations, and they often take advantage of text obfuscation techniques to bypass traditional email security measures. In addition, these AI-powered attacks are often more effective than manual phishing tactics.
Additionally, attackers can use AI to create deepfakes—artificial media that resembles real-life footage but has been digitally altered to pose as a malicious individual or organization. This can be used to spread misinformation, extort victims by threatening to release an unflattering video or audio recording of them, and even gain unauthorized access to accounts, services, or sensitive information. These threats can damage reputations and cause significant financial losses, so it’s important for organizations to invest in employee training and establish a culture of cybersecurity awareness.
