Remote Exploits
An exploit is a method or piece of code that takes advantage of vulnerabilities in software, applications, networks, operating systems, or hardware, typically for malicious purposes. The term "exploit" derives from the English verb "to exploit," meaning "to use something to one’s own advantage." Exploits are designed to identify flaws, bypass security measures, gain unauthorized access to systems, take control of systems, install malware, or steal sensitive data. While an exploit by itself may not be a malware, it serves as a vehicle for delivering malicious software by breaching security controls. Researchers estimate that malicious exploits cost the global economy over US$450 billion annually. In response to this threat, organizations are increasingly utilizing cyber threat intelligence to identify vulnerabilities and prevent hacks before they occur. Description Exploits target vulnerabilities, which are essentially flaws or weaknesses in a system's defenses. Common tar ...

Vulnerability (computer Security)
Vulnerabilities are flaws or weaknesses in a system's design, implementation, or management that can be exploited by a malicious actor to compromise its security. Despite a system administrator's best efforts to achieve complete correctness, virtually all hardware and software contain Software bug, bugs where the system does not behave as expected. If the bug could enable an attacker to compromise the confidentiality, Data integrity, integrity, or availability of system resources, it can be considered a vulnerability. Insecure software development practices as well as design factors such as complexity can increase the burden of vulnerabilities. Vulnerability management is a process that includes identifying systems and prioritizing which are most important, scanning for vulnerabilities, and taking action to secure the system. Vulnerability management typically is a combination of remediation, mitigation, and acceptance. Vulnerabilities can be scored for severity according to the ...

Patch (computing)
A patch is data that is intended to be used to modify an existing software resource such as a computer program, program or a computer file, file, often to fix software bug, bugs and security vulnerability, security vulnerabilities. A patch may be created to improve functionality, usability, or Computer performance, performance. A patch is typically provided by a vendor for updating the software that they provide. A patch may be created manually, but commonly it is created via a tool that compares two versions of the resource and generates data that can be used to transform one to the other. Typically, a patch needs to be applied to the specific version of the resource it is intended to modify, although there are exceptions. Some patching tools can detect the version of the existing resource and apply the appropriate patch, even if it supports multiple versions. As more patches are released, their cumulative size can grow significantly, sometimes exceeding the size of the resource ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Security Agency

FORCEDENTRY
FORCEDENTRY, also capitalized as ForcedEntry, is a security exploit allegedly developed by NSO Group to deploy their Pegasus spyware. It enables the " zero-click" exploit that is prevalent in iOS 13 and below, but also compromises recent safeguards set by Apple's "BlastDoor" in iOS 14 and later. In September 2021, Apple released new versions of its operating systems for multiple device families containing a fix for the vulnerability. Exploit The exploit was discovered by Citizen Lab, who reported that the vulnerability has been used to target political dissidents and human rights activists. FORCEDENTRY appears to be the same as the attack previously detected and named "Megalodon" by Amnesty International. The exploit uses PDF files disguised as GIF files to inject JBIG2-encoded data to provoke an integer overflow in Apple's CoreGraphics system, circumventing Apple's "BlastDoor" sandbox for message content. BlastDoor was introduced as part of iOS 14 to defend against KISMET ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spoofing Attack
In the context of information security, and especially network security, a spoofing attack is a situation in which a person or program successfully identifies as another by falsifying data, to gain an illegitimate advantage. Internet Spoofing and TCP/IP Many of the protocols in the TCP/IP suite do not provide mechanisms for authenticating the source or destination of a message, leaving them vulnerable to spoofing attacks when extra precautions are not taken by applications to verify the identity of the sending or receiving host. IP spoofing and ARP spoofing in particular may be used to leverage man-in-the-middle attacks against hosts on a computer network. Spoofing attacks which take advantage of TCP/IP suite protocols may be mitigated with the use of firewalls capable of deep packet inspection or by taking measures to verify the identity of the sender or recipient of a message. Domain name spoofing The term 'Domain name spoofing' (or simply though less accurately, 'Domain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Denial Of Service (computing)
In computing, a denial-of-service attack (DoS attack) is a cyberattack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to a network. Denial of service is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fulfilled. The range of attacks varies widely, spanning from inundating a server with millions of requests to slow its performance, overwhelming a server with a substantial amount of invalid data, to submitting requests with an illegitimate IP address. In a distributed denial-of-service attack (DDoS attack), the incoming traffic flooding the victim originates from many different sources. More sophisticated strategies are required to mitigate this type of attack; simply attempting to block a single source is insuffic ...

Elevation Of Privilege (computing)
Privilege escalation is the act of exploiting a Software bug, bug, a Product defect, design flaw, or a configuration oversight in an operating system or software application to gain elevated access to resource (computer science), resources that are normally protected from an application or user (computing), user. The result is that an application or user with more privilege (computing), privileges than intended by the programmer, application developer or system administrator can perform Authorization, unauthorized actions. Background Most computer systems are designed for use with multiple user accounts, each of which has abilities known as Privilege (computing), privileges. Common privileges include viewing and editing files or modifying system files. Privilege escalation means users receive privileges they are not entitled to. These privileges can be used to delete files, view personal data, private information, or install unwanted programs such as viruses. It usually occurs whe ...

Social Engineering (security)
In the context of information security, social engineering is the use of psychological influence of people into performing actions or divulging Confidentiality, confidential information. This differs from psychological manipulation in that it doesn't need to be controlling, negative or a one-way transaction. Manipulation involves a zero-sum game where one party wins and the other loses while social engineering can be win-win for both parties. A type of confidence trick for the purpose of information gathering, fraud, or system access, it differs from a traditional "con" in the sense that it is often one of many steps in a more complex fraud scheme. It has also been defined as "any act that influences a person to take an action that may or may not be in their best interests." Research done in 2020 has indicated that social engineering will be one of the most prominent challenges of the upcoming decade. Having proficiency in social engineering will be increasingly important for orga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
