In phishing attacks, attackers gain access to confidential data and information. For companies, this often has fatal financial consequences. We provide an overview of the most important information on the subject of phishing.
Phishing (“password + fishing”) is a method of cyber attack in which fraudsters use fake messages such as e-mails, text messages or advertising banners to pose as a trustworthy source. The aim is to trick users into revealing confidential information or data. This information is then used for fraudulent activities, such as identity theft or financial abuse – often with far-reaching consequences for small and medium-sized companies. Successful phishing attacks have increased steadily in recent years, with perpetrators developing ever more sophisticated methods to lure their victims. Entrepreneurs should therefore be aware of the risks and take sufficient precautions to protect themselves from phishing attacks.
Email phishing is one of the most common forms of phishing attacks. In this scenario, attackers send fake emails en masse to a wide range of recipients. These emails often contain links to fake websites that resemble those of trusted companies, or they contain malicious attachments. The senders try to trick the recipients into clicking on these links or opening the attachments in order to disclose personal information or install malicious software, such as ransomware, on their computers. Unlike broad-based email phishing, “spear phishing” targets specific individuals or organizations. Attackers do advance research and customize their fake messages specifically for the potential victim. These personalized messages are often more convincing and harder to detect because they often contain details known only to the victim. In phishing attacks, attackers manipulate domain name system (DNS) records or computer hosts files to redirect victims to fake websites, even if they type in the correct web address. This unknowingly directs users to fake websites where they enter sensitive information that is captured by the attackers. In CEO fraud, attackers pose as senior executives or CEOs of a company and send fake emails to employees, often to the finance department. These emails often demand urgent money transfers or the disclosure of confidential information to supposed business partners. Because the messages appear to come from the highest level, employees are more likely to fall for these scams. Vishing (voice phishing) involves scammers using phone calls to obtain sensitive information. The callers often pose as bank, government or IT department employees and ask the victims to disclose personal information or passwords over the phone. Social media phishing involves creating fake social media profiles or pages to trick users into disclosing personal information. Attackers often use the trust built on such platforms to persuade victims to share their data or click on malicious links.
Phishing attacks have far-reaching effects that can affect both individuals and the entire company. The consequences range from financial losses to serious reputational damage.
Volksbanken Raiffeisenbanken (2021): In 2021, the German Federal Central Tax Office warned against phishing emails that claimed to be from the agency. The emails informed recipients of an alleged tax refund and asked them to click on a link to request more information. The aim was to steal personal information or distribute malicious software.

Deutsche Telekom (2020): Deutsche Telekom warned its customers about fraudulent emails claiming that their bills were due.

Federal Employment Agency (2020): In 2020, the Federal Employment Agency was the target of a phishing attack in which fake e-mails were sent on behalf of the agency. These e-mails also contained links to fake websites that asked recipients to enter personal information and access data.

Detecting phishing attacks at an early stage is a fundamental step in mitigating potential risks and thus maintaining the security of your own company and affected customers. A first step can be to watch out for unusual requests and promises. Phishers often use pressure tactics to get victims to act quickly, for example by threatening to lose account access. Users should always be skeptical when offered unexpected rewards, quick profits, or financial benefits. Checking links and sender addresses is another important step in detecting phishing attempts. Cybercriminals often use manipulated links that look authentic but lead to fake websites designed to steal login information or personal data. It is advisable to check the link before clicking on it, for example by moving the mouse over it to display the actual URL. You should also check the sender address carefully to make sure it matches the expected domain. Grammar and spelling mistakes are also a common sign of phishing. Many phishing emails come from countries with a different native language and therefore often contain a noticeable number of mistakes. Using text-based AI, it is now easy to avoid such mistakes, but fraudsters do not always use it. Phishing detection technology has also evolved. Many email services and security software use algorithms and databases to identify suspicious emails and move them to the spam folder. Companies are also increasingly relying on training and awareness programs for their employees to make them aware of the dangers of phishing and to strengthen their ability to recognize suspicious activity. Trufflepig Forensics offers Phishing Awareness training and can help you keep your organization and employees aware of such attacks over time. Overall, detecting phishing attempts is a combination of common sense, technical knowledge, and advanced security tools.
