The risk of falling victim to a successful ransomware attack remains high. According to a recent study, two-thirds of all German companies became targets of ransomware malware in 2021 - and the threat is growing every year. As attackers come up with increasingly aggressive strategies, many companies find themselves tempted to meet the hackers' high ransom demands. In some cases, the financial implications take on drastic proportions. If you don't want to be the next victim, you should act now.

Growing cybercrime threat scenarios pose a serious risk to data security, business continuity, and corporate reputation. Extortion with encryption software continues to grow. For companies and organizations, it is a worst-case scenario with incalculable consequences if they can no longer use their IT due to ransomware attacks, their business data falls into foreign hands or production lines simply come to a standstill. On average, attackers still need six months to achieve their mission objective. An attack can be analyzed in three phases: intrusion (access to the system), propagation (spread) and endgame (mission objective) - the kill chain model.

Brute force attacks attempt to gain access to protected files or entire systems by automatically trying out password combinations or keys at random. The method uses the eponymous "brute force", in which strings or sequences of letters are tried one after another. The more time the attackers have, the more combinations can be tried - and the higher the chances of success. Find out here what brute force attacks are exactly, what they are used for and, of course, how you can reliably protect yourself against this form of cybercrime.

For many, a publicly accessible WLAN is a welcome opportunity to conserve their own mobile data volume. Sometimes these networks are even faster than the mobile network. Unfortunately, public WLAN networks are also interesting for cybercriminals: They can easily obtain personal data there if WLAN users have not taken sufficient care of security while surfing. We present the biggest risks and show how you can protect yourself from them.

The damage caused by ransomware worldwide in 2021 amounts to around 20 billion US dollars. This is an increase of around 5,700% compared to 2015 - and the trend is still rising. Companies that do not take care of the necessary in-house IT security in good time therefore run the risk of falling victim to these attacks sooner or later and, in the worst case, suffering losses in the millions. The attackers do not "discriminate": public institutions are attacked just as much as privately managed companies or companies listed on the stock exchange. Virtually every sector is affected, from skilled trades and industry to the financial and technology sectors.

A recent study shows: Attacks on the software supply chain are particularly lucrative for cybercriminals. A single hack within the supply chain is enough to infect several thousand companies with malware in one go. So it's no wonder that the criminal business with attacks on software components is booming - not least because supply chain security is often neglected. It would be very easy to close the security gaps with innovative solutions.

Cyber criminals have no industry boundaries. Even companies with a good IT security department can be affected by a cyber attack. What to do if it is successful? Experts use the term "incident response readiness" to summarize how to react appropriately in an emergency. Our article contains important first aid measures. It also shows how you can prepare your company to keep damage to a minimum in the event of a hacker attack. After all, a long-term and well thought-out strategy against cyber attacks pays off for all company stakeholders.
