Digital fraud never takes a break. Every year, scammers get smarter, their tricks more convincing, and spotting them becomes harder.

Picture this: you get a call from someone claiming to be your bank’s fraud team. They know your name, sound professional, and warn you about “suspicious activity.” Their urgent advice? Move your money into a “safe account.” It feels real, it feels urgent—but it’s a trap.

Or maybe it’s a WhatsApp message: “Mum, I’ve lost my phone. Can you help me pay something quickly?” Designed to play on emotion and bypass logic, these scams succeed precisely because they feel personal.

Why digital fraud is surging in 2025

The rise of digital fraud isn’t just hurting individuals—it’s hitting businesses, banks and even governments. As more of our lives move online, the attack surface grows larger than ever.

The numbers back it up fraud reports in the UK show double-digit growth year-on-year, with phishing, smishing and identity theft topping the charts.

But there’s good news too. Cybersecurity technology has caught up. Tools now exist that not only detect threats but prevent fraud before it happens. That’s where Lleida.net comes in: building digital trust into every interaction.

Fighting today’s digital fraud ccams with Lleida.net

1. The fake tax authority email (phishing)

Still one of the most effective scams: criminals impersonate tax agencies like HMRC or the IRS. The emails look official, the branding is polished, and the links lead to credential-harvesting sites.

Solution

With Registered Email from Lleida.net, authenticity is guaranteed. Only verified senders can use it, so you know exactly who’s contacting yo

Only pre-verified senders can use the service, so the address you see genuinely belongs to the person or organisation contacting you. Every message is routed through Lleida.net’s secure infrastructure, adding a neutral digital witness between sender and recipient. Visible security markers—DKIM signatures and DMARC policies—evidence authentication and deliver messages straight to the inbox rather than spam folders, and you can brand the sender domain to make authenticity clear at first glance.

Crucially, each registered email generates a digital evidence record containing sender details, timestamps and attachments—proof that the file the recipient opens is undoubtedly the one that was sent. The certificate can also be shared automatically with the recipient for full transparency.

Technology is powerful, but good hygiene still matters: keep software updated, use strong passwords and enable multifactor authentication. Combine those best practices with Registered Email, and phishing loses its bite.

2. The “delivery service” text message (smishing)

It looks harmless: “Your parcel is being held. Pay £2/$2 to release it.” The small fee lowers defences, and once card details are entered, money and personal data flow straight to the criminals.

The most sophisticated versions use spoofing, inserting the fake text into the same SMS thread as genuine updates from Royal Mail, FedEx or USPS. Sitting alongside real messages, the fake looks authentic.

Solution

With Openum from Lleida.net, organisations send registered notifications through WhatsApp, a secure, verified channel. v traceable in real time.

Openum also adds legal and technical weight. Communications across email, SMS and WhatsApp carry full evidentiary value. Documents open in a secure, encrypted viewer (HTTPS/TLS 1.2, AES-256, ISO 27001), so there’s no risky downloading or running external software—minimising ransomware and malware exposure. Where extra assurance is needed, you can require a shared code, OTP or 2FA before access.

Instead of leaving customers wondering whether a message is genuine, Openum makes authenticity obvious from the start.

3. The contract that “changed” after signing

Tampering with signed documents is more common than you’d think. In one case, a contract was quietly edited after both parties signed; in another, a scanned image of a signature was pasted onto a PDF to make it look valid. Disputes like these escalate quickly—and without reliable evidence, they’re challenging to win.

Solution

With Click & Sign, manipulation is impossible without leaving a trace. Every stage of the signature process—from the initial send by a pre-verified sender, through the recipient’s interactions, to final delivery—is captured in a registered digital evidence record, time-stamped, digitally sealed and custodied under ISO 27001:2022. As a Qualified Trust Service Provider (QTSP) under eIDAS, Lleida.net guarantees authenticity, integrity, non-alteration and precise time stamping—ensuring non-repudiation.

If you need to validate documents received from outside your organisation, the Universal Signature Verifier checks electronic signatures in all major standards—XAdES, CAdES, PAdES, Facturae, UBL, among others. It integrates via API to automate validation at scale and supports long-term custody requirements, so you can prove integrity years later.

4. The customer who never existed

Imagine running an online store. An order arrives, you ship the goods—and later discover the “customer” never existed. The address was fake, the payment details invalid. You’re left with lost stock and no recourse. As e-commerce grows, this synthetic identity fraud is rising.

Solution

Certvalidator from Lleida.net integrates directly into your platform to verify users with digital certificates at registration and login. Whether personal or legal-entity certificates, only credentials issued by recognised, trusted authorities are accepted—closing the door on fictitious accounts.

The result: fewer chargebacks and stock losses, stronger KYC at checkout and a safer, more trustworthy purchasing experience.

5. Identity theft in online banking

One of the most damaging—and widespread—frauds is identity theft. Criminals use stolen or fabricated IDs to open accounts, launder money, apply for loans or execute unauthorised transfers. The financial, reputational and compliance risks are enormous.

Solution

Banks worldwide rely on eKYC Video from Lleida.net to verify customers remotely. The process combines document checks (front/back capture, OCR, MRZ validation and fraud signals), facial recognition and liveness detection (prompted gestures) to confirm the user is a real person—not a screenshot, not a scan, not a deepfake. The entire journey—images, video with audio, validation results and configured parameters—is recorded and certified, producing legally admissible evidence across jurisdictions (EU eIDAS, GDPR, and local AML/KYC/CTF frameworks).

Deployment is fast—live in under 48 hours—and the service integrates via API or a ready-to-use branded URL, ensuring compliance without friction.

By raising the bar for identity verification, eKYC Video makes impersonation—the fraudster’s favourite tactic—far harder to pull off.

The bigger picture

Fraud is evolving fast. So are the defences. From phishing emails to fake customers, the pattern is the same: scams thrive on doubt. If victims hesitate, criminals win.

At Lleida.net, our job is to remove that doubt. By combining legal certainty with advanced digital-trust solutions—registered email and SMS, secure messaging with Openum, Click & Sign, eKYC Video and universal signature validation—we make every digital interaction simple, verifiable and, above all, trusted.

Lleida.net provides extra protection against digital fraud across industries.

Expanding into Spain—or managing a subsidiary here—means working within one of Europe’s most regulated labour markets. Employment contracts, data protection and compliance requirements can slow down HR teams and add unnecessary complexity.

The good news: Spain fully recognises electronic signatures for employment contracts. This allows you to hire, onboard and manage employees entirely online, with the same legal certainty as traditional paper processes.

Spain has regulated eSignatures for more than 20 years. It began withRoyal Decree-Law 14/1999, later consolidated in Law 59/2003, and today is governed by the EU’s eIDAS Regulation (910/2014) together with Spanish Law 6/2020 on trusted electronic services.

This legal framework makes electronic signatures one of the most secure and efficient tools for digital HR. No wonder 83% of Spanish companies already use them in their internal processes. The same rules apply to international businesses.

At Lleida.net, a qualified trust service provider, we help companies worldwide manage their Spanish workforce with Click & Sign, our electronic signature platform that combines security, efficiency, and complete legal compliance.

The impact of electronic signatures on HR

Electronic signatures have become indispensable for HR departments, particularly in staffing agencies and consultancies. They simplify document management, automate repetitive tasks, reduce delays and ensure compliance with Spanish and EU law at every stage of the employee lifecycle.

Cloud-based services make it easier to design a smooth candidate and employee experience. They provide security, traceability, efficiency and legal validity. At Lleida.net, our solutions are updated seamlessly, so HR teams can always benefit from the latest features.

From data protection consent forms (required under Spain’s LOPDGDD and the EU GDPR) to employment contracts, settlement agreements and tax forms such as IRPF withholding certificates—all can be signed 100% digitally, with full legal standing and maximum convenience for both employer and employee.

Benefits of using electronic signatures in employment contracts

Electronic signatures, like handwritten ones, are legally valid and record the signatory’s consent. But they offer clear advantages for HR:

• Real-time tracking and secure storage
  Processes are tracked live, ensuring compliance and accuracy. Documents are stored securely for at least five years (extendable if needed), alongside additional records such as IDs, passports or registered certificates. Editable PDFs automatically capture entered data, keeping HR files centralised in one secure repository.

Is it legal in Spain to sign employment contracts electronically?

Yes. Electronic signatures are entirely legal and binding in Spain and across the EU, provided they comply with the eIDAS Regulation (EU 910/2014)and Spanish Law 6/2020on trusted electronic services.

All Lleida.net services adhere strictly to this framework, ensuring every transaction meets the highest standards of security, interoperability and validity, locally and globally.

Types of electronic signature under eIDAS

The eIDAS Regulationdefines three levels of electronic signature, each with different degrees of security and evidential strength. Click & Sign supports all three, so you can choose the level that best fits your business needs.

Simple electronic signature (SES)

• Best for low-risk processes or internal documentation.

• Lower probative value.

Advanced electronic signature (AES)

• Ensures the signatory’s identity and link to the document.

• Adds an extra layer of protection with a one-time password (OTP), sent via Registered Email, Registered SMS or Registered WhatsApp. The signatory enters the unique code to finalise the process, ensuring authenticity.

Qualified electronic signature (QES)

• Legally equivalent to a handwritten signature.

• Requires a qualified registered certificate.

• Used in high-assurance legal contexts.

Strong security and probative evidence

Every signature completed with Lleida.net is supported by authentication, integrity and non-repudiation mechanisms. This ensures the document cannot be altered and the signatory's identity is always clear.

Each transaction generates documentary evidence that records every event in the process. This file is digitally signed and timestamped, protecting its authenticity and integrity from creation through to secure storage.

The documentary evidence serves as registered proof, providing strong evidence that can be presented in court if required. Timestamping reinforces the long-term validity of the signature, even years after the signing took place.

Cloud-native security and automation

Companies are increasingly moving to 100% cloud-based solutions instead of on-premise systems. The cloud offers greater flexibility, lower costs and automatic updates, all without adding pressure on IT teams.

Beyond signatures: registered notifications for HR

Electronic signatures aren’t the only digital HR tool in Spain. With Lleida.net, you can also certify the delivery, receipt and opening of an email or SMS—providing the digital equivalent of Spain’s traditional burofax (registered post).

Key services for HR digitalisation

With Lleida.net, you can digitalise the entire HR lifecycle in Spain—from data collection and employee communication to secure document management and storage.

Spain’s Organic Law 1/2025 (LO 1/2025) on measures to improve the efficiency of the Public Justice Service has placed Alternative Dispute Resolution (ADR) at the centre of Spanish legal practice, making it a mandatory prerequisite in civil and commercial proceedings.

Within this new legal framework, an unprecedented event marks a turning point: the first Spanish Provincial Court ruling that validates Registered Email as a legitimate way to certify an ADR process.

This ruling not only reinforces the importance of ADR under LO 1/2025 but also provides much-needed clarity, reducing legal uncertainty surrounding mediation procedures since the law came into force. By recognising Registered Email as equivalent to the traditional registered post (burofax), the court consolidates it as a legally valid tool for communicating binding offers in commercial transactions. A faster and more efficient solution already used successfully by Lleida.net clients to optimise resources and ensure compliance.

What is ADR (MASC)?

ADR (in Spanish, Medios Adecuados de Solución de Controversias – MASC) refers to mandatory mechanisms to resolve disputes before claims can be admitted in civil and commercial courts, including those with an international dimension.

These methods —mediation, conciliation, and negotiation— encourage dialogue and collaboration, allowing parties to reach agreements through peaceful and voluntary means.

LO 1/2025 reinforces the importance of mediation and negotiation, requiring parties to provide verifiable proof of attempted ADR before taking a case to court. This ensures a faster, more cooperative judicial process.

Case background

The case was filed by a creditor against a debtor. Before going to court, the creditor sent a Confidential Binding Offer (CBO) to the debtor via Registered Email, in compliance with LO 1/2025.

However, the Commercial Court initially dismissed the case, claiming that the ADR requirement had not been proven with sufficient documentation.

The first Spanish ruling recognising ADR via Registered Email

The Provincial Court of Alicante (Ruling No. 48/2025) took a different approach. It explicitly stated that “there is no obstacle to using email as the method of communication,” thus recognising Registered Email as an effective and valid medium, thanks to:

• Verified sender identification.
• Proof of effective receipt.
• Reliable timestamp, ensuring confidentiality of content.

Importantly, the ruling clarifies that prior agreement between the parties to use email is not required. This reinforces a functional, non-formalistic interpretation of the ADR prerequisite.

The Court also referred to Article 3.1 of the Spanish Civil Code, which requires laws to adapt to “the social reality of their time.” In today’s business environment, email is an ordinary channel of communication — provided authenticity and integrity are guaranteed.

This interpretation aligns with guidelines from the Spanish General Council of Lawyers, which equates Registered Email to traditional burofax for ADR compliance.

The probative value of Registered Email

Today, Registered Email is a widely accepted and reliable communication tool across Spanish business practice. Its legal strength is supported by both EU and Spanish regulations, provided it is issued by a Qualified Trust Service Provider such as Lleida.net.

Legal foundations

Registered Email is legally recognised under a solid framework, including:

• Spanish Civil Code (1889)
• Spanish Criminal Code (1995)
• Civil Procedure Law (2000)
• Law on Information Society Services (2002)
• General Telecommunications Law (2014)
• Law 6/2020 on trust services
• EU Regulation 910/2014 (eIDAS)

The eIDAS Regulation explicitly states that electronic delivery services cannot be denied legal effect or admissibility as evidence in court solely because they are electronic.

This Regulation explicitly establishes that “data sent and received through an electronic registered delivery service shall not be denied legal effect or admissibility as evidence in legal proceedings solely on the grounds that they are in electronic form or do not meet the requirements for qualified electronic registered delivery services.”

Recent case law and various judicial rulings in Spain have reinforced this interpretation, recognizing the full legal validity of Registered Email in both commercial and procedural contexts.
