In Luxembourg, phishing has long targeted businesses that handle payments, customer data, and regularly communicate via email. The problem is that these attacks are becoming increasingly sophisticated. Messages are increasingly well-written, fake websites mimic official interfaces, and warning signs are becoming more subtle.
A misinterpretation, a hasty click, or an unverified validation can be enough to trigger fraud. These tips will help you limit risks for your business and react quickly in case of an incident.
What is phishing?
In Luxembourg, as elsewhere, phishing is a form of fraud designed to deceive an individual or organization into divulging sensitive information... Or to induce them to perform a risky action, such as making a payment or sharing confidential documents.
The definition of phishing is therefore quite simple. However, the phenomenon can take various forms, all of which you may encounter in your professional activities:
- Email phishing: the message imitates a known entity (bank, service, institution) and prompts you to click on a link or open a malicious attachment.
- Spear phishing: the message is personalized with real information about your company or contacts, making it much more credible.
- Vishing: the fraud occurs over the phone, with a caller attempting to impersonate a bank advisor, technical support, a business partner, etc.
- Pharming: a subtle redirection leads you to a fake website with the aim of obtaining personal and financial information.
- Whaling: more targeted than spear phishing, the message targets executives or high-responsibility profiles within your company.
- Smishing: an SMS prompts you to open a fraudulent link, usually by creating a sense of urgency.
Are phishing attempts common in Luxembourg?
Phishing attacks have significantly increased in Luxembourg, alongside the digitalization of businesses and the widespread adoption of online exchanges.
Initially, attempts were relatively basic and easily identifiable. They resembled mass spam: with generic messages sent on a large scale, often poorly translated or lacking credibility.
Over time, however, cybercriminals have refined their methods. They directly target Luxembourgish companies, particularly in the financial, insurance, and administrative sectors. Phishing is no longer as random. It now relies on precise data and professional contexts.
How to protect yourself against phishing attacks?
In most cases, phishers don't "force" their way into a system. Instead, they exploit their targets' inattention and hasty actions.
Here's what you can do to effectively protect yourself against phishing:
- Do not share any sensitive information via email or phone.
- Always hover over a link to display its address before clicking on it.
- If in doubt, check the website address in your browser.
- Contact the organization directly to confirm any communications received.
- Use different, secure passwords for each website and application.
- Enable two-factor authentication on your sensitive accounts.
- When possible, check the last login dates and times for your accounts.
How to tell if you've been a victim of phishing?
Identifying a phishing attempt after the fact isn't always easy. In most cases, you discover the fraud either because an unusual action was performed on your behalf, or because certain elements of your digital environment no longer match your habits.
However, certain signs can alert you well in advance: an offer that's too good to be true, a strange sender address, an attachment that looks like a fake document...
Familiarize yourself with some common phishing examples that regularly affect Luxembourgish companies to improve your detection capabilities. Fake bank emails, offers to "secure" accounts, and password update requests are among the most well-known.
What to do in case of phishing in Luxembourg?
In case of phishing in Luxembourg, the priority is to act quickly, structure your actions, and immediately limit the impact on your systems and financial flows.
As soon as you suspect fraud or a compromise, follow this process:
- Contact the relevant organization (bank, supplier, platform, or service).
- Block your accounts/cards if banking data has been leaked.
- Keep evidence of the fraud.
- Immediately change your passwords.
Once the situation is stable, file a complaint with the competent Luxembourgish authorities.
How to report phishing in Luxembourg?
To report a phishing attack in Luxembourg, file a complaint with the Luxembourg Police. Make sure to provide as much specific information as possible to aid the investigation, such as phone numbers used, names and addresses of fraudulent websites, or copies of received emails.
Finally, report phishing emails and SMS messages to the CIRCL (Computer Incident Response Center Luxembourg).
Note: if falsified documents or proofs were used to deceive you, you can use document fraud like Finovox to build a strong case file.
