What are phishing attacks?

Phishing attacks are a form of social engineering. Cyber criminals attempt to steal confidential information such as passwords, credit card numbers or access data. This is usually done using fake emails, websites or messages that imitate legitimate sources. The attackers use psychological tricks, to trick the recipient into disclosing sensitive data or clicking on malicious links. Phishing is one of the oldest and most effective methods used by cyber criminals - and for good reason: It relies on human trust and curiosity.

The most common forms of phishing

Phishing is not always obvious. There are various methods that attackers use to deceive their victims. The most common include:

1. E-mail phishing: The classic method of sending fake emails from seemingly trustworthy sources such as banks, online services or even business partners.
2. Spear phishing: This targeted variant is aimed at specific people or companies. The attackers use personalized information to increase the credibility of their messages.
3. Whaling: A special form of spear phishing aimed at high-ranking executives. This often involves large sums of money or valuable company data.
4. Smishing and vishing: Phishing via SMS (smishing) or telephone calls (vishing). These methods are becoming increasingly popular as they often require fewer technical security mechanisms to be bypassed.

How to recognize phishing attacks

Recognizing a phishing attack is often the first step in protecting yourself. There are certain characteristics, which may indicate a phishing attempt:

• Unusual senders: Check the sender's e-mail address carefully. Attackers often use addresses that look similar to those of trusted organizations, but have small differences. An example would be a sender address that uses „@micrsoft.com“ instead of „@microsoft.com“.
• Visual cues: Look out for visual irregularities in the email, such as inconsistent logos, incorrect fonts or unusual layouts.
• Urgency and scaremongering: Phishing messages often create an impression of urgency or threat in order to urge the recipient to react quickly. Examples include warnings about account blocking or unauthorized transactions.
• Grammatical and spelling errors: Professional companies pay attention to the quality of their communication. If a message contains several spelling mistakes, you should be suspicious.
• Suspicious links and attachments: Hover over links to see the actual URL before you click. If the link looks suspicious or leads to an unknown page, do not open it. Also pay attention to so-called subdomains. A link to „microsoft.xydomain.com“ is guaranteed not to take you to Microsoft.
• Unusual requests: Be careful if an e-mail contains unexpected requests for personal or financial information.

Protective measures for your company

1. Employee training: Regularly sensitize your employees to the dangers of phishing. Training and simulated phishing attacks can help to raise awareness and improve the recognition of such threats.

3. Two-factor authentication (2FA): Implement two-factor authentication for all important systems and accounts. Even if a password is stolen, it is useless without the second factor.
4. Email filters and security protocols: Use advanced email filters that automatically flag or block suspicious messages. These filters should be updated regularly to keep up with the latest threats. Set up DMARC (Domain-based Message Authentication, Reporting & Conformance), SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) in your email communication.
5. Verification of payments: Implement processes in which larger financial transactions or sensitive data transfers are always checked by a second person.
