Phishing is a form of cybercrime. Attackers use emails, text messages, messaging apps, or phone calls to steal sensitive information. They often want access to online banking or company accounts.
This leads to unauthorized withdrawals or identity theft. Ransomware attacks are also possible.
Phishing is based on social engineering. Attackers try to create pressure by using subject lines such as “Your account will be suspended.” They want victims to act quickly.
That is why it is important to stay alert. This helps you reliably identify phishing and avoid mistakes.
In Germany, both consumers and businesses are affected. Executives and IT managers are particularly at risk. Recommendations from the Federal Office for Information Security (BSI) and banks such as Commerzbank are helpful.
Police recommendations offer additional protection. Key tips for phishing prevention include using official contact channels, not sharing sensitive information by email, and checking phone numbers on official websites.
These measures help minimize phishing risks. They strengthen protection against phishing over the long term.
Recognizing phishing: common signs of phishing emails and messages
It is important to recognize fraudulent messages. This helps you prevent phishing attacks. Knowing the common signs helps you stay safer in everyday life.
How phishing works and common attack channels
Phishing uses various methods, such as email, text messages, messaging apps, and phone calls. Attackers want to steal login credentials or install malware.
There are various types of phishing, including mass phishing and targeted attacks. Real-time phishing allows attackers to use information immediately.
Suspicious signs in the sender address and subject line
The sender’s name can be forged. Check the domain extension and look for typos. Unknown senders are a warning sign.
Subject lines can create pressure, for example by setting deadlines. Be cautious if there is no personalized greeting. Vague wording and urgency are intended to prompt a quick response.
Recognizing dangerous links, attachments, and macros
Do not click links blindly. Check the actual URL. To access your bank account, enter the address manually or use bookmarks.
Do not open unexpected attachments. Requests to enable macros are especially dangerous. Macros can download additional malware.
Personalization, writing style, and AI-powered deception
Attackers use social media profiles and company websites to personalize messages. Even personalized greetings do not guarantee authenticity.
Artificial intelligence creates deceptively realistic text and voices. Well-written emails are not proof of trustworthiness. Requests for a PIN, TAN, or photoTAN activation should still be treated with suspicion.
| Identifying feature | What it means | Specific action |
|---|---|---|
| Sender address | Typos, unfamiliar domain, unknown service | Check the address carefully, compare the domain, do not reply |
| Subject line | Urgency, threats, vague wording | Do not panic, set the message aside, use official channels |
| Links | Shortened URLs, mismatched destination address | Check by hovering over the link, do not click it, navigate to the destination manually |
| Attachments & macros | Unknown files, request to enable macros | Do not open the attachment, use antivirus software, notify IT |
| Personalization | Public information used, unexpected greeting | Verify identity independently, remain skeptical |
| Communication channel | Text message, messaging app, phone call, or email | Check the contact channel, never send sensitive information through unsecured channels |
Recognizing phishing emails: practical checks and guidelines
Clear routines are important for recognizing phishing emails. Quick checks often help expose fraudulent messages. Here are practical tips you can use in everyday life.
Address bar, bookmarks, and direct navigation
Checking the address in your browser is a good first step. Secure websites start with https:// and display a padlock. If there is no certificate, do not proceed.
Bookmark frequently used login pages. This helps you avoid logging in through email links. When in doubt, navigate to the provider’s homepage manually.
Do not share sensitive information by email
No reputable provider asks for PINs, passwords, TANs, or photoTAN images by email or phone. This rule helps prevent phishing. It is a key aspect of phishing prevention.
When in doubt, use the phone numbers listed in the official legal notice or on your bank card. Enter sensitive information only through the provider’s encrypted forms.
What to do about suspicious attachments and downloads
Never open questionable attachments or enable macros. Such files may contain malware and compromise accounts.
Only download files from official websites. In a business setting, notify the IT security department so files can be analyzed in a secure environment.
Keep antivirus software up to date and install system updates promptly. These measures improve your chances of being able to reliably identify phishing and block it.
Precautions for phone calls and voice messages
Do not share login credentials or install remote diagnostic software during suspicious calls. End the call immediately if you are pressured.
Only return calls using the organization’s official phone numbers. Do not use numbers from suspicious messages. Ignore voicemails with unusual content and block the numbers.
- Check account balances regularly to detect unauthorized withdrawals early.
- Use bookmarks and strong passwords to help you recognize phishing emails.
- Attend training so employees put phishing prevention into practice every day.
Defending against phishing attacks: technical and organizational safeguards
Preventing phishing requires technology and processes. This lays the foundation for long-term security. Here are measures you can take to defend against phishing attacks.
Basic security measures for endpoint devices
Everything must always be up to date. Updates protect against attacks. This helps you effectively defend against phishing attacks.
Antivirus software and firewalls are important. Device encryption and strong passwords protect data. Biometrics provide additional protection.
Two-factor authentication (2FA) is very effective. It is a simple way to protect yourself.
Phishing safeguards for individuals and businesses
2FA should be used everywhere. When transferring money, requiring approval by two people helps prevent fraud.
Do not use shared logins. Everyone needs their own account. PINs and photoTAN images must not be saved.
Emergency procedures are important. Blocking accounts and calling account-blocking hotlines help you act quickly.
Using technical filters and security solutions
Email filters with SPF, DKIM, and DMARC improve security. Anti-phishing gateways increase detection rates.
URL scanning and sandboxing block malicious content. A web proxy with URL reputation checks provides protection in the browser.
MDM and EDR are important for businesses. They improve responses to attacks and prevent phishing.
Training and security awareness
Regular training and phishing simulations increase vigilance. Exercises help people recognize fraud.
Executives need specialized training. Clear procedures for making secure decisions are important.
Awareness materials from BSI and others are helpful. Internal channels are useful for sharing information quickly.
Conducting phishing tests and responding appropriately after an incident
Organizations should conduct exercises regularly. This helps employees recognize threats and act faster. Phishing tests reveal gaps in knowledge and where training is needed.
Internal phishing tests and learning from simulations
Realistic simulations, such as spear-phishing scenarios, reveal the level of security awareness. Results are used for training, not punishment. Regular testing and learning are important.
Specific steps to take after clicking a phishing link or disclosing data
Anyone who clicks a phishing link should stay calm and act immediately. Change passwords and block accounts. Check systems for malware and install updates.
Using contact channels and reporting services
If you suspect phishing, contact your bank immediately. Use official contact channels. Report suspicious emails to IT security and BSI.
Recovery and minimizing damage
Block access and use TAN procedures. Introduce a 4-eyes approval process for payments. Review transactions and report unauthorized debits.
Targeted follow-up improves phishing security. Regular tests and clear reporting channels help you respond quickly and minimize risks.
Conclusion
Recognizing phishing is an ongoing task. It combines technical safeguards with clear rules and continuous security awareness. Being cautious when receiving unexpected messages and sharing no sensitive data by email provides strong protection.
Important safeguards include 2-factor authentication and regular updates. Up-to-date antivirus software and email authentication with SPF, DKIM, and DMARC are also important. Businesses should introduce internal processes such as requiring approval by two people.
If you suspect phishing, use official contact channels and block accounts. Also check affected devices. These steps help prevent phishing and limit damage. Training and technical improvements are important for staying secure over the long term.
