Airbnb, CNN, Netflix, PayPal, Spotify, Visa, Amazon, the New York Times, Reddit, and GitHub have all been the targets of a distributed denial-of-service (DDoS) attack.
A DDoS is a popular attack used by a hacker to divert the attention of its victim. As the victim tries to eliminate the dangers of the DDoS attack, the cybercriminal swoops in with its primary motivation, which could be anything from installing malicious software to stealing your organisation’s data.
This kind of attack can cost the victim a great deal of time and money to handle, so it is important that you and your employees are informed about the dangers of a DDoS attack.
Learn more about this kind of cyber attack in the guide below.
What is a DDoS attack?
In most cases, if a website has been brought down by hackers, the victim has been subjected to a DDoS attack.
Hackers will use a DDoS attack to shut down a machine or network.
DoS attacks can make it impossible for users to access their machines or networks as the attack floods the target with traffic or sends the system information that can trigger a crash.
A DoS attack will deprive legitimate users of access, which means employees, members, or account holders will be blocked from access.
What is the difference between a DoS and DDoS attack?
DoS stands for denial-of-service attack. This kind of attack floods a server with TCP and UDP packets.
A DDoS attackis a kind of DoS attack, where multiple systems target a single system with a DoS attack.
Examples of a DDoS attack
There are several symptoms of a DDoS attack. However, many of these are like other issues you may have with your device (i.e. a virus or a slow running Internet connection).
Issues that can be caused by a DDoS include:
Slow access to files
A long-term inability to access a website
Problems accessing all websites
An excessive volume of spam emails
If you are experiencing two or more of these issues, you might be a victim of a DDoS.
Rise of DDoS attacks
Why should your organisation be concerned about these attacks?
Security Brief has revealed that the number of DDoS attacks doubled in Q1 2020 as attackers are targeting remote workers during the Coronavirus pandemic.
Cyber security experts have suggested that hackers are taking advantage of the fact that remote employees are becoming more reliant on online resources than ever before and many organisations have allocated resources to remaining stable and accessible during the outbreak.
Security Brief has warned that:
“If cyber attackers can gain the trust of a victim by masquerading as a reputable source, such as the World Health Organisation or any given country’s Ministry of Health, then attacks are more likely to succeed.”
