Final comments from our Head of Incident Response  

In 2025, the team at Pentest People see cyber threats escalating with more sophisticated ransomware using “double extortion,” This is where attackers both encrypt data and then threaten to leak it. We saw a brief decline over the last 12 months but think it will pick up pace again in 2025.

This trend is compounded by the growing vulnerability of non-human identities such as APIs and automated systems, often poorly monitored and updated less than conventional systems. Expect to see these targeted more frequently by attackers as exploits become increasingly available. It is turning out to be, as expected, a double-edged sword, empowering both attackers and defenders. Threat actors now leverage AI to create advanced Phishing and malware that evade detection. This misuse will only increase as AI bots start to automate tasks. Looking further still, quantum computing is fast approaching, putting pressure on organisations to adopt post-quantum encryption to stay secure.

Final Thoughts: In 2025, defence strategies will need to be proactive and layered. A solid approach will mean bolstering Incident Response, keeping playbooks sharp with regular Tabletop Exercises (TTX), and leveraging Threat Intelligence (TI) for constant monitoring. These services, alongside a strong Endpoint Detection and Response (EDR), are essential to catching threats early and reacting quickly.
