An increasing number of brute force attacks on Fritz!Box routers are currently being detected.
What is behind the hacker attack and what users need to know now.
Kassel – Cyber attacks have enormous potential for damage.
In April 2023, several federal state public portals fell victim to hackers.
Last year, the digital association Bitkom put cybercrime damage in Germany at 203 billion euros.
According to the Federal Criminal Police Office (BKA), cybercrime crimes in Germany remain at a “very high level”.
In 2022 alone, the police registered over 130,000 cases of cybercrime.
Hacker attack on Fritz!Box routers – particularly those with remote access affected
Cyber criminals recently wanted to access private customer data with a hacker attack on the lottery.
Criminals also use the phishing scam to try to get their victims' personal data and money.
In another case, fraudsters stole thousands of euros using a fraudulent SMS.
Brute force attack
A brute force attack is an attack method in which hackers use trial and error to try out many possible combinations to decrypt passwords.
If the entry is successful, criminals can gain access to the user account and steal data there.
Therefore, experts always recommend passwords that are too complex.
Fritz!Box users are currently being targeted by attackers.
According to the online portal
giga.de,
many users are currently reporting unwanted login attempts on their AVM routers, especially those with active remote access.
IT expert Günter Born first referred to this on his website
“borncity”
after a reader brought it to his attention.
The person concerned looked at the event log of his Fritz!Box and noticed an “immense number of access attempts” in the past few days.
The method probably indicates a brute force attack.

Hacker attack on Fritz!Box router: This is how you can protect your device
Every Fritz!Box has an event log.
This shows all login attempts including the IP address - including failed access attempts, which may also include hacker attacks.
As the online magazine
golem.de
reports, the external attacks reported apparently all come from the same IP address (193.46.255.151).

According to tarnkappe.info
, users who allow remote access to their Fritz!Box routers should
take the following measures to prevent unwanted, external access attempts:
Changing the default passwords:
To ensure that cyber criminals don't have an easy time with the brute force attack, the Fritz!Box's default password should be changed.
Strong passwords make unwanted, external access more difficult
Activating the firewall:
A firewall can help prevent unwanted data traffic and at the same time increase the security of your network.
Deactivation of public access:
Complete deactivation of remote access would make sense if it is not absolutely necessary.
If you can't do without the function, you should activate two-factor authentication for those who are authorized for remote access.
VPN Setup:
When public access is enabled, a Virtual Private Network (VPN) provides a secure way to access your network.
Regular updates:
The Fritz!Box should always be up to date to close security gaps.
It is not yet known who exactly is behind the current attacks.
