هجوم BLACKNURSE

BLACKNURSE Attack One Device Shutdown the Most Powerful Servers

Many of the cyber attacks in recent times have become more widespread are denial of service attacks that do not require skills in dramatic tests important. Imagine now the hacker easily reduces the denial of service package is very strong and imaginary and the lowest servers only all that Hua needs one computer only with BLACKNURSE attack .

The researchers have now confirmed that the hacker can launch an attack with limited resources only for one laptop and at the same time accept at least 15Mbps data and shutdown a large server.

Here the attack is called the BlackNurse Attack or the low rate of the Ping of Death attack.

The attack is executed by sending a small packet of ICMP packets, which are short for Internet Control Message Protocol or pings, which puts heavy pressure on firewall-protected server processors such as Cisc.

How does the attack work?

Many of the cyber attacks in recent times have become more widespread. Additionally, denial of service attacks has emerged as a prominent threat that doesn’t necessarily require advanced hacking skills. One such attack gaining attention is the BLACKNURSE attack, which showcases the power of a simple yet devastating technique.

Researchers have now confirmed that a hacker can launch this attack with minimal resources, even using just a single laptop. Astonishingly, with a mere 15Mbps data, they can successfully bring down a large server, causing significant disruption.

The BLACKNURSE attack, also known as the low rate of the Ping of Death attack, leverages the sending of ICMP packets, commonly referred to as pings. These seemingly innocuous packets put immense pressure on firewall-protected server processors, including those of renowned brands like Cisco.

 

Vulnerable Products:

First– Cisco ASA 5506, 5515, 5525 (default settings)

Second- Cisco ASA 5550 (legacy) and 5515-X (latest generation)

– Cisco Router 897 (can be mitigated)

– SonicWall (misconfiguration can be changed and mitigated)

– Some unverified Palo Alto

– Zyxel NWA3560-N (wireless attack from LAN side)

– Zyxel Zywall USG50

Information security engineers can detect the attack by using special IDS tools such as SNORT to detect attack.

There has also been a significant increase in Denial of Service attacks in recent years. Due to significant damage to private companies and government facilities and may be more damaging than penetration.

In the end, there were also tools available to do this attack, checking the infected IP addresses and where Cisco has fixed the problem in the products. Many companies are still vulnerable to attacks, denial of service and causing the worst damage in history.
