A very warm hello!
Email is still one of the most important means of communication in everyday business. Invoices are released, payments are confirmed and confidential information is exchanged. It is precisely this trust that cybercriminals exploit. One of the most dangerous and at the same time successful scams in recent years is Business Email Compromise (BEC).
In a business email compromise, attackers pretend to be trustworthy people or organizations in order to manipulate employees. The goal is usually to trigger money transfers or to receive sensitive information. Especially often, executives such as CEOs are imitated to exploit pressure and trust at the same time. But it is also possible that providers are imitated with whom you are in a business relationship.
When the CEO suddenly writes an urgent email
A classic scenario looks like this:
An accounting or finance employee receives a seemingly urgent e-mail from the managing director. In it, for example, a short-term transfer is requested – for example for a confidential project or an allegedly time-critical invoice. The message looks authentic because the name of the CEO appears as the sender.
In reality, however, the email comes from an attacker. This type of fraud is often referred to as CEO fraud is a typical form of business email compromise. Attackers use targeted hierarchies and time pressure so that employees do not question the request.
Social engineering instead of technical attacks
Business Email Compromise often uses targeted Social engineering. Attackers manipulate people by exploiting trust and creating targeted pressure.
To do this, they often research publicly available information about a company and employees in advance, such as the names of executives. For this, the attackers use, among other things, social media or press releases as a source. An illegal resource is also the Dark Web, which can contain already leaked information such as access data about the attack target.
With this information, attackers can deceptively formulate real messages that are hardly distinguishable from legitimate communication.
Fake domains and email spoofing
To make their emails more credible, cybercriminals often pick up Email spoofing or fake domains back. An email address is manipulated in such a way that it looks like a legitimate address at first glance. Fake domains can easily deviate from the real domain, for example by an exchanged letter.
Such minimal differences are often not noticeable in the hectic working day. Employees trust the message – and carry out the requested action.
Often these techniques are also used with Spear phishing combined. These are particularly targeted attacks on individual persons or departments, which are prepared individually and thus have a particularly credible effect.
The consequences for companies
The impact of a successful business email compromise can be significant. In addition to direct financial losses, long-term damages also threaten:
- Fraudulent transfers with large sums
- Loss of sensitive company data
- Reputational damage to customers
- Possible legal or compliance risks
Most critically, many of these attacks remain undetected at first, as they look like normal business communications.
The Limits of Classical Cybersecurity
Many companies invest heavily in technical security solutions such as firewalls or endpoint protection. These systems are important but primarily protect the internal infrastructure.
Business Email Compromise primarily uses Trust and communication as an attack vector. As a result, such attacks can handle classical security mechanisms.
Effective protection therefore requires a holistic approach that also takes into account external threats – such as fake domains, phishing campaigns or abused brand identity.
Proactive detection and rapid reaction
In order to detect BEC attacks at an early stage, continuous monitoring of the external attack area is crucial. This includes, in particular, the observation of newly registered domains similar to their own brand.
If a fraudulent domain is detected, it should be responded quickly before it is used for phishing or CEO woman.
Conclusion: Trust is the largest attack area
Business Email Compromise shows that modern cyber attacks not only exploit technical vulnerabilities. Often the confidence within companies is targeted.
If attackers imitate CEOs, business partners or internal employees, even cautious persons can be deceived. It is therefore crucial to monitor both internal processes and the external digital presence of a company.
Get active now
Many BEC attacks begin with fake domains or manipulated email addressesthat resemble a company domain strongly.
We help companies identify such threats at an early stage. This includes, for example, the identification of suspicious domains and, if a fraudulent domain is detected, its removal by targeted takedown processes.
Let your domain landscape check and protect your company from Business Email Compromise before attackers can exploit the confidence of their employees.
