krebs hit by massive ddos routers
On September 20, 2016, cybersecurity expert Brian Krebs became the victim of one of the largest and most sophisticated Distributed Denial of Service (DDoS) attacks in internet history. The attack, which lasted for over 24 hours, brought down Krebs’ website, KrebsOnSecurity.com, and disrupted internet service for millions of users around the world. But who was behind this attack and why did they target Krebs? In this article, we will delve into the details of this massive DDoS attack and its impact on both Krebs and the internet as a whole.
First, let’s understand what a DDoS attack is and how it works. DDoS attacks are a type of cyber attack where a large number of compromised computer s, known as a botnet, are used to flood a target website or server with traffic. This overwhelms the target’s servers, causing them to crash and become inaccessible to legitimate users. DDoS attacks have been around since the early days of the internet, but their frequency and sophistication have increased significantly in recent years.
Now, back to the attack on Krebs. On the morning of September 20, Krebs’ website started to experience a massive surge in traffic, with over 665 gigabits per second (Gbps) of data being sent to his servers. This is equivalent to streaming over 60,000 high-definition movies at the same time. The attack was so powerful that it overwhelmed the servers of Akamai, the company that provided DDoS protection for Krebs’ website. As a result, Akamai was forced to drop Krebs’ website from its network, effectively taking it offline.
But who was responsible for this attack? Initially, it was believed that a group of cyber criminals was behind it, as Krebs had been a vocal critic of various cybercrime organizations in the past. However, as more details of the attack emerged, it became clear that this was not the work of a criminal gang. Instead, it was a highly sophisticated attack carried out by a group of hackers known as the Mirai botnet.
The Mirai botnet is a network of thousands of compromised Internet of Things (IoT) devices, such as cameras, routers, and DVRs, that are controlled by a central command and control server. The Mirai botnet was first discovered in late 2016 and has been used to carry out several high-profile DDoS attacks, including the attack on Krebs’ website. The botnet was created by a group of hackers who were looking for a way to utilize the large number of vulnerable IoT devices to launch massive DDoS attacks.
So, why did the Mirai botnet target Krebs? The answer lies in the fact that Krebs had recently published an article exposing the source code of the Mirai botnet. The botnet’s creators were unhappy with this and saw Krebs as a threat to their operations. Therefore, they decided to launch a massive DDoS attack on his website as a form of retaliation.
The attack on Krebs’ website was not just a personal vendetta against him. It had far-reaching consequences for the internet as a whole. The attack on Krebs was one of the largest DDoS attacks ever recorded, and it sent shockwaves throughout the cybersecurity community. It showed that even the most secure and well-protected websites could be taken down by a determined attacker using a botnet like Mirai.
Furthermore, the attack highlighted the vulnerabilities of IoT devices and the potential threat they pose to the internet. These devices are often designed with little to no security, making them easy targets for hackers to exploit. With the increasing popularity of IoT devices, it is becoming easier for hackers to create large botnets like Mirai and use them to launch devastating DDoS attacks.
The aftermath of the attack on Krebs’ website also brought to light the issue of companies offering DDoS protection services. A few days after the attack, KrebsOnSecurity.com was back online, but this time it was being protected by Google’s Project Shield. This raised questions about the effectiveness of companies like Akamai in providing DDoS protection and whether they were equipped to handle attacks of this magnitude.
The attack on Krebs also sparked a debate about the responsibility of IoT device manufacturers in securing their products. Many experts argued that manufacturers should be held accountable for the security of their devices and should be required to implement stronger security measures to prevent them from being compromised and used in botnets like Mirai.
In the end, the attack on Krebs’ website was a wake-up call for the internet community. It exposed the vulnerabilities of IoT devices and the potential threat they pose to the internet. It also highlighted the need for companies to invest in stronger DDoS protection measures and for IoT device manufacturers to prioritize security in their products.
In conclusion, the massive DDoS attack on Brian Krebs’ website was a significant event in the history of the internet. It showed the power and sophistication of modern-day DDoS attacks and the potential impact they can have on the internet. It also highlighted the need for increased security measures and collaboration among internet service providers, cybersecurity experts, and IoT device manufacturers to prevent such attacks in the future.
how does bitdefender ransomware protection work
Ransomware has become a major threat in today’s digital world, with cybercriminals using it to extort money from individuals and organizations. To combat this growing problem, many antivirus software companies have developed ransomware protection features. One such company is Bitdefender, a leading cybersecurity company that offers a comprehensive ransomware protection solution. In this article, we will take a closer look at how Bitdefender ransomware protection works and why it is an essential tool in today’s digital landscape.
Before diving into how Bitdefender ransomware protection works, let’s first understand what ransomware is. Ransomware is a type of malware that encrypts files on a computer or network, making them inaccessible to the user. The cybercriminal then demands a ransom payment in exchange for the decryption key, allowing the victim to regain access to their files. Ransomware attacks can be devastating to both individuals and businesses, as they can result in the loss of sensitive data, financial loss, and damage to a company’s reputation.
Bitdefender’s ransomware protection feature is part of its advanced security suite, which is designed to protect users from all types of cyber threats. The feature uses a multi-layered approach to detect and block ransomware attacks, ensuring the safety of your files and data. Let’s explore the different layers of protection that Bitdefender offers against ransomware.
Real-Time Threat Detection
Bitdefender’s ransomware protection works by constantly monitoring the user’s system for any suspicious activity. This is done in real-time, meaning that the protection is always active and ready to detect and block any potential threats. The software uses behavioral analysis and machine learning algorithms to identify and stop ransomware in its tracks. By analyzing the behavior of programs and files, Bitdefender can detect and block ransomware attacks before they can do any harm.
Anti-Ransomware Vaccine
Bitdefender has also developed a feature called the Anti-Ransomware Vaccine, which adds an extra layer of protection against ransomware attacks. It works by creating a fake file that simulates a ransomware attack, tricking the malware into thinking that the system has already been infected. This prevents the real ransomware from encrypting any files, giving the user enough time to back up their data and remove the threat.
Web Protection
Another way Bitdefender protects against ransomware is through its web protection feature. This feature blocks access to websites that are known to distribute ransomware or other types of malware. It also prevents users from downloading malicious files from the internet, further reducing the risk of a ransomware attack. Additionally, the web protection feature scans all incoming and outgoing traffic for any signs of ransomware, providing an additional layer of defense.
Advanced Threat Defense
Bitdefender’s advanced threat defense is a proactive approach to ransomware protection. It uses sandboxing technology to isolate suspicious files and programs and run them in a virtual environment. This allows Bitdefender to analyze the behavior of these files without risking the user’s system. If the file is found to be malicious, Bitdefender will block it from executing, preventing a potential ransomware attack.
Ransomware Remediation
In the unfortunate event that ransomware does manage to infect a user’s system, Bitdefender’s ransomware remediation feature comes into play. This feature automatically restores any encrypted files from a backup, eliminating the need to pay the ransom. It also removes any traces of the ransomware from the system, ensuring that the threat is completely eradicated.
Anti-Spam Filter
Many ransomware attacks are initiated through malicious emails, which is why Bitdefender’s anti-spam filter is an essential part of its ransomware protection. This feature scans incoming emails for any signs of ransomware or other malware, blocking them before they can reach the user’s inbox. It also filters out spam emails, reducing the chances of a user accidentally clicking on a malicious link.
Multi-Layered Protection
As you can see, Bitdefender’s ransomware protection works through a multi-layered approach, providing users with comprehensive protection against ransomware attacks. The combination of real-time threat detection, anti-ransomware vaccine, web protection, advanced threat defense, ransomware remediation, and anti-spam filters creates a robust defense against ransomware.
Ease of Use
One of the best things about Bitdefender’s ransomware protection is its ease of use. The software runs quietly in the background, without interrupting the user’s workflow. It requires minimal setup and configuration, making it accessible to users of all technical levels. The user can also customize the level of protection they want, giving them control over their cybersecurity.
Constant Updates
Bitdefender’s ransomware protection is constantly updated to stay ahead of the latest ransomware threats. The software regularly receives updates and patches, ensuring that users are protected against all known ransomware variants. This proactive approach to cybersecurity is crucial in today’s ever-evolving threat landscape.
In conclusion, Bitdefender’s ransomware protection is an essential tool for anyone looking to safeguard their files and data from malicious cyber threats.
