Thanks to a previously unknown vulnerability in iOS, this exploit, without any user input, triggered the execution of malicious code that connected to a C2 server and gradually loaded additional malicious payload. It first elevated privileges using additional exploits and then launched a full-blown ...
A proxy server is an intermediary between a user and the internet. It's a dedicated computer or software-driven service that acts as an intermediary orgatewaybetween an endpoint or client device, such as a computer, and a server on the internet. The computer makes requests for resources and ...
they consist of a header, payload, and trailer and include a destination and source address, which respectively signify where they’re headed and where they originate. Although packets travel between networks, frames do so between computers — therefore, they’re at Layer 2 of theOpen Systems In...
HTTP GET attack: Multiple computers or other devices are coordinated to send multiple requests for images, files, or other assets from a targeted server. When the target is inundated with incoming requests and responses, denial-of-service will occur to additional requests from legitimate traffic sou...
What is malware? Malware, short for malicious software, is designed to steal data and damage or destroy computers or computer systems. Learn about malware What is phishing? Phishing is the practice of sending fraudulent communications that appear to come from a legitimate and reputable source. ...
Virus is often a catch-all term used to refer to any kind of software created to be harmful. But a virus is just one type of malware, and the definition of a virus is that it’s a computer program that can self-replicate, infect other programs, and spread to other computers. How ...
In these cases, the extra code borne by the worm is known as its “payload.” One common strategy equips worms with a payload that opens a “backdoor” onto infected machines, allowing a cybercriminal to return later to take control of the system. Other payloads can harvest sensitive ...
‘payload’ refers to the part of the computer virus that causes harm, whatever that harm may be. In other words, the virus stays dormant until it’s time for it to execute its actions. A virus is either triggered to act by the user’s actions or by a specific deadline programmed ...
This exercise is about more than preparing to respond effectively to future attacks. It’s also about determining what can be done to avoid another attack. For example, if the worm penetrated a network, what vulnerability did it use to obtain access and has that vulnerability been fully addres...
Just as Bob is one endpoint of his and Alice's conversation, a computer connected to a network is one endpoint of an ongoing data exchange. Everyday examples of endpoints include desktop computers, smartphones, tablets, laptops, and Internet of Things (IoT) devices. What is not an endpoint...
