Warning: Identity fraud

We've recently seen an increase in fraud cases involving identity theft, where personal identities are being misused without consent. Please review the following information carefully to understand how these scams typically unfold—and how to protect yourself.

What is identity fraud?

Identity fraud occurs when scammers impersonate trusted organizations—such as companies or government agencies—in order to commit further crimes like investment fraud. They pose as advisors, brokers, analysts, or financial experts and often present forged documents, such as trading licenses, cooperation agreements, or IDs, to appear legitimate.

In many cases, they also mimic the websites of well-known institutions and reach out via email or phone while pretending to represent those organizations.

How can you spot identity fraud?

The first contact often comes through modern channels like social media platforms or messenger apps. It may also happen after you click on what seems like a trustworthy online ad and submit your contact information.

Scammers typically follow up via a foreign phone number or WhatsApp call. You’ll be presented with an investment opportunity promising high returns and asked to transfer funds or crypto to a designated—usually foreign—bank account or crypto wallet.

Oftentimes, you're shown fake profits on a website that looks legitimate but is actually a scam. When you try to cash in on these supposed profits, you're asked to pay taxes, fees, or other charges upfront.

How can you protect yourself from identity fraud?

Be cautious of unsolicited contact from people claiming to represent trusted organizations. Always verify their identity via official contact channels.
Question any investment offers that seem too good to be true.
Don’t share personal information unless you’ve verified the legitimacy of the request.
Only use official company websites—and double-check the URL if you’re unsure.
Never allow remote access to your devices (e.g. via AnyDesk or similar software).
If in doubt about an offer or a request, consult a consumer protection agency.
Report suspicious outreach to authorities or the company being impersonated.

What are common scam tactics?

Scammers pose as BSDEX or Boerse Stuttgart Group employees on platforms like LinkedIn or Xing.

You’re contacted by a supposed financial analyst.
You’re offered a “lucrative investment” or asked to verify your identity to protect your account or approve a transaction.

The sender claims to be a financial advisor or employee of BSDEX or the Boerse Stuttgart Group.

Note: Scammers often use spoofing (methods to conceal identity) to make emails or calls appear as though they’re coming from an official BSDEX or Boerse Stuttgart Group address or number. If you’re unsure, contact our support team at support@bsdex.de. How can I confirm that I’m actually communicating with BSDEX?

Unfortunately, there have been instances where individuals have falsely claimed to represent BSDEX. Considering this, please keep the following points in mind.

We can only be reached through the following official websites:

Out official email addresses are:

BSDEX would never contact you via any other email address.

Do not share any sensitive data like personal information, log-in data, wallet addresses, or SMS TANs with third parties and do not enter them on websites other than those mentioned above.

Note: If you’re asked to enter personal information on a different website, notify us immediately at support@bsdex.de with the subject “Suspected Fraud.”

If you receive an email from an unfamiliar address claiming to be from BSDEX, we strongly advise you not to respond. Instead, report it as spam or phishing through your email provider.

Keep login data secure

Store your login data in such a way that third parties cannot access them. Never share your access data (email & password) with third parties, especially not with strangers.

Do not make TAN accessible to third parties

If unauthorized persons gain access to your email and password, the TAN protects you from having the account taken over. For this reason, you should not make the TAN that you receive via your smartphone accessible to third parties. Especially, you should only enter your own number for the phone number.

BSDEX employees do not ask for access data

We will never ask you for your access data. Nor will we ask you for screen sharing. If someone asks for your access data via email or phone, be careful and do not share it under any circumstances.

Keep your computer and browser up to date

Outdated software can more quickly lead to your device being taken over by fraudsters. Therefore, always keep your computer and browser up-to-date to ensure maximum security. Also, an anti-virus tool - especially for Windows devices - can be useful.

In case of doubt contact the support

If you notice any unusual activity on your account, receive suspicious calls or emails you do not trust, please contact our support at support@bsdex.de as a precaution.

Browse in secure networks

Logging into public networks, such as the wifi in a hotel, restaurant or train station, always creates a certain security risk. Avoid logging into financial apps like BSDEX's on public networks to ensure more security.

How to avoid common Phishing attacks

How BSDEX is working on making the platform safe

For banks and insurance companies in particular, security is considered one of the most important factors. The more securely one's assets are stored with a company, the greater the trust. Security in the custody of cryptocurrencies is probably even more important than with traditional banks. BSDEX is working every day to make the platform even more secure.

Why the KYC is so important for your account security

Phishing usually refers to emails that pretend to be another person. In particular, phishing emails are sent in the name of well-known companies in order to obtain users' access data. Phishing attacks also occur via telephone calls. In this case, the scammers pretend to be employees of a company in order to obtain the victims' access data. This article tells you how to recognize phishing attacks and prevent them.The KYC procedure is often perceived as annoying in the crypto world. Yet it is quite normal to verify oneself when opening an account. The verification of one's own account, i.e. the assignment of the account to a specific person, with the help of official documents such as the ID card, protects our customers, for example, in situations where fraudsters try to gain access to other people's accounts. You can find out what else a KYC is good for in the following article.

High security due 2FA

Multifactor authentication has significantly increased security on the Internet. While it used to be enough to simply hack an account's password, thanks to 2FA or 3FA a fraudster can't do anything with your account even if he has the access data. This is because further authentication - for example, a code sent by SMS - is required. You can find out more about multi-factor authentication in our Academy.

Why Anti Money Laundering (AML) is important

In every larger company there are people whose job it is to prevent money laundering in their own company. Money laundering can also be done by customers, for example, by exchanging money in cryptocurrency and sending it to unknown wallets. BSDEX takes several precautions to prevent money laundering. You can learn why this is important for your security in this article.

You are asked to make a deposit, tax payment, security deposit or similar as proof of identity, for verification or to unlock the funds to which you are allegedly entitled
You are repeatedly contacted and asked to make investments and transactions

If applicable, trustworthy, established providers as well as authorities or other official institutions or their representatives are also named as parties involved - however, you have never been in contact with them regarding this matter
Registration with the third-party provider requires only a few details and no procedure is used to verify the identity of customers in accordance with the legitimisation regulations for banks and financial service providers

The third-party provider claims that it has been "successfully" established on the market for years or that it cooperates with BISON, although this cannot be independently verified

You have discovered a third-party provider that promises you unusually high returns
The third-party provider offers you various "investment plans" in which you apparently only have to pay in a minimum amount and the provider "guarantees" you certain profits in return
The third-party provider brags about its "professional trading", "arbitrage trading", "AI trading", "forex trading" or "cloud mining" without pointing out any risks

"Lucrative job offer" scam

Faking a job offer in order to obtain financial benefits, commit identity theft and pass on payments from third parties
You have been made aware of a lucrative job offer with great earning potential on the internet or through acquaintances.

You are asked to provide the supposed employer with your ID details by email for the recruitment process.
As an employee, you are supposed to pay your new employer around 250 euros for your work equipment
Payments are received in your account, which you are supposed to transfer to other accounts
You are supposed to open accounts in your own name with banks or other financial service providers, but leave access to the supposed employer
