Cyber criminals use DDoS attacks to make websites and other online services unavailable for legitimate use.
Distributed denial of service (DDoS) is a broad class of cyberattack that disrupts online services and resources by overwhelming them with traffic. This renders the targeted online service unusable for the duration of the DDoS attack. The hallmark of DDoS attacks is the distributed nature of the malicious traffic, which typically originates from a botnet—a criminally-controlled network of compromised machines spread around the globe.
Buffers are regions of memory storage that temporarily store data while it’s being transferred from one location to another. A buffer overflow, also known as a buffer overrun, takes place when the volume of data is more than the storage capacity of the memory buffer. Resultantly, the program that tries to write the data to the buffer replaces the adjacent memory locations. If a user enters 10 bytes, that is 2 bytes more than the buffer capacity, the buffer overflow occurs.
Credential stuffing is one of the most common forms of online crime, it is the act of testing stolen passwords and usernames against website login forms, to validate the credentials for malicious reuse. Once a match is found, the attacker can easily commit various types of fraud. When credentials are stolen through a database breach, malware, or other means, they are kept for use in future attacks against many different targets.
Amazon Web Services (AWS) said that it mitigated a distributed denial-of-service (DDoS) attack with a volume of 2.3 Tbps. In its “Threat Landscape Report – Q1 2020,” AWS Shield revealed that its team members had spent several days responding to this particular network volumetric DDoS attack. In Q1 2020, a known UDP reflection vector, CLDAP reflection, was observed with a previously unseen volume of 2.3 Tbps.
The COVID-19 pandemic has unveiled numerous vulnerabilities and shortcomings in the airline industry. What’s worse for aviation in particular over other industries is how airports have essentially served as the portal for the virus traveling from one country to another across the globe. As a result of severe travel restrictions implemented by nearly every country, airline companies have been hit hard and forced into a dire financial situation.
All National Health Service (NHS) and social care organisations in the United Kingdom have always been and will always be a target for bad actors. The nature of their business and the sensitive data they hold make these entities appealing to bad actors who know that legacy systems, and/or, not regularly patched systems, such as those employed by healthcare organizations are easy to penetrate.
As companies face increasingly sophisticated cyber threats, they often turn to technology solutions to help protect their data and systems from attacks. But what happens when your company is in the technology industry? Cyberattacks are increasingly targeting technology companies who often store and handle significant amounts of sensitive data, including personally identifiable information and intellectual property on behalf of their customers.
You're probably familiar with the defense-in-depth or castle and moat approach to cybersecurity. It remains a common model that organizations use to think through their information security. However, as organizations have matured they have sought out new models to enable them to better understand how cyber attackers operate and how best to defend against them.
