As 2025 approaches, cybercriminals continue to evolve at an alarming pace, exploiting human, technological, and organizational vulnerabilities.
This article highlights the most likely cybersecurity threats for the coming year and provides you with key strategies to strengthen your defenses.
Social engineering is not a new threat, but it has reached a new level in recent years, thanks to the use of artificial intelligence (AI).
Cybercriminals are refining their techniques to deceive victims by leveraging deepfakes—AI-generated audio or video content that perfectly mimics a voice or face. These deepfakes make attacks nearly undetectable, even for experienced users.
Unlike traditional phishing, these new forms of social engineering exploit audio and visual cues, tapping into our instinctive perception of reality. These attacks are highly personalized, increasing their success rates and exploiting a universal vulnerability: human trust.
Vocal Deepfake: A CEO receives a call from a key colleague whose voice sounds authentic. The caller urgently requests a money transfer for a “critical opportunity.” In reality, it’s a deepfake used to divert funds.
Visual Identity Theft: A video of a “friend” sent via email invites the recipient to click on a link. The seemingly legitimate video contains instructions that lead to a malicious site.
Targeting Family Members: A parent receives a video showing their child allegedly in danger, accompanied by a ransom demand.
Enhance Training on Emerging Threats:
Educate your teams about the risks posed by deepfakes. For instance, conduct workshops to teach them how to identify subtle clues, such as poorly synchronized lip movements or unnatural audio transitions.
Adopt Anti-Phishing Solutions:
Invest in tools capable of analyzing communication patterns to detect anomalies, such as unusual phrases or suspicious behaviors in emails.
Deploy Deepfake Detection Tools:
Use specialized software that analyzes the metadata of multimedia files and detects video or audio manipulations. These tools are essential for companies handling sensitive information.
Implement Verification Protocols:
Before executing financial transactions or sharing sensitive information, confirm via a second channel (direct call, secure message). For example, require physical confirmation or a real-time video call.
The security of your systems no longer depends solely on your own protective measures but also on those of your suppliers, subcontractors, and partners.
Cybercriminals exploit weak links in the supply chain to gain access to primary targets. These attacks can cause massive damage to businesses and individuals, including compromising sensitive data or disrupting operations.
For Businesses:
A partner’s compromise can result in the loss of sensitive data, service interruptions, or even legal penalties if client information is exposed.
For Individuals:
When service providers (banks, telecoms, e-commerce) are hacked, your personal information (bank accounts, login data, etc.) is at risk.
Third-Party Payer Operators Cyberattack (2024):
Companies like Viamedis and Almerys, managing third-party payments for numerous health insurance providers, were victims of coordinated cyberattacks. These incidents exposed the personal data of over 33 million insured individuals, including civil status, birth dates, and social security numbers.
Data Breach at Free (2024):
The telecom operator Free suffered a cyberattack targeting a management tool, granting unauthorized access to the personal data of millions of customers, including banking information such as IBANs.
Conduct Regular Partner Audits:

The widespread adoption of cloud solutions has profoundly transformed how users store, share, and access their data.
While this shift offers undeniable advantages in terms of flexibility and efficiency, it also introduces growing risks.
Misconfigurations, poor management practices, and complex interdependencies between cloud platforms expose sensitive data to cybercriminals. Cloud services, often used to store critical information—whether personal photos, confidential documents, or device backups—have become prime targets due to their wealth of exploitable data.
For Businesses:
Poorly configured cloud environments can lead to disastrous consequences, ranging from massive data breaches to prolonged service disruptions, resulting in financial losses and reputational damage.
For Individuals:
Mismanaged cloud settings can expose personal information to unauthorized access, putting privacy and financial security at risk.
The increasing complexity of cloud infrastructures also complicates the identification and management of vulnerabilities, making a proactive approach essential to mitigate risks.
Automate Cloud Configuration Monitoring:
Conduct Regular Cloud-Specific Penetration Tests:
Segment Critical Environments to Limit Risks:
DNS tunneling is a malicious technique that exploits the Domain Name System (DNS) protocol to exfiltrate data or communicate with compromised systems.
Normally, DNS translates human-readable domain names (e.g., example.com) into IP addresses used by computers. However, in a DNS tunneling attack, cybercriminals encode data into DNS queries, allowing it to pass through firewalls disguised as legitimate DNS traffic.
This method makes malicious activities particularly difficult to detect.
Detection Challenges:
DNS traffic is typically allowed by firewalls and security systems, enabling attackers to mask malicious activities.
Legitimate Protocol Use:
Since DNS is essential to the internet’s functionality, organizations are reluctant to restrict or block this type of traffic.
Adaptability:
Attackers can modify their strategies to evade detection tools, rendering traditional defenses ineffective.
Adopt Real-Time DNS Monitoring Solutions:
Filter Unnecessary DNS Queries:
Strengthen Network Segmentation to Limit Lateral Movements:
Good digital hygiene involves adopting consistent practices to secure systems, devices, and data against cyber threats.
In 2024, insufficient digital hygiene remained one of the primary causes of compromises.
Cybercriminals exploit simple vulnerabilities, such as weak or reused passwords, to breach systems and online accounts. These gaps expose users to financial losses, client data breaches, identity theft, and reputational damage.
