What is Heartbleed Bug? (How it Works, Vulnerable Devices, How to Prevent
Heartbleed is a critical flaw in the widely used OpenSSL cryptographic software library. This flaw allows information to be stolen that is usually secured by the SSL/TLS cryptography used to secure the Web. SSL/TLS enables communication privacy and security for the internet, mail, messaging services, and some VPNs over the internet.A defect in OpenSSL's implementation of the TLS Heartbeat extension causes the Heartbleed problem, which results in improper input validation.It's an open-source software vulnerability that was initially discovered in 2014. Anyone with access to the Internet can use this flaw to access the memory of system vulnerabilities, leaving no trace ...
Read MoreWhat are Backdoor Trojans?
Backdoor Trojans are malicious software programs that provide unauthorized access to a computer in order to launch a remote attack. Remote attackers can use a hacked machine to send commands or gain complete control.Backdoor malware and viruses circumvent authentication protocols in order to gain access to systems and avoid detection. Once a Trojan has gained a footing in a system, it adds itself to the starting routine of the computer, preventing harmful programs from being permanently terminated by rebooting the machine.Backdoor malware is commonly referred to as a Trojan. A Trojan horse is a malicious computer software that masquerades as ...

Read MoreWhat is Rogue Security Software? (Features, What It Does, How to Prevent)
Rogue security software is a malicious software that deceives users into believing their computer is afflicted with a virus in order to induce them to pay for a phony malware removal application that really installs malware. It is a type of scareware that manipulates victims by instilling fear in them, as well as a type of ransomware. Since 2008, rogue security software has posed a severe security concern to desktop computers. SpySheriff and its clones were an early example that acquired notoriety.Rogueware is a type of ransomware that is frequently associated with huge cybercrime networks in which hackers distribute Trojan ...
Read MoreWhat is Fast Identity Online (FIDO)? (Benefits, Is It Secure, How Does It Work)
What is FIDO?FIDO (Fast ID Online) is a collection of technology-neutral solid authentication security protocols. The FIDO Alliance, a non-profit organization dedicated to standardizing authentication at the client and protocol layers, created FIDO.The FIDO specifications support multifactor authentication (MFA) and public-key cryptography. FIDO keeps it locally on the user's device to protect personally-identifying information (PII), such as biometric authentication data, rather than in a password database.The Universal Authentication Framework (UAF) and the Universal Second Factor (U2F) protocols are supported by FIDO. During registration with an online service, the client device establishes a new key pair using UAF and keeps the ...

Read MoreWhat are Autorun Worms? (How Do They Spread, How to Remove, How to Prevent)
Autorun Worms, which are commonly disseminated via USB devices, are a "surprise attack" that uses the Windows Auto-Run feature (autorun.inf) to execute malicious code without user knowledge when an infected device is connected to a computer. Many variants of this exploit make use of Windows' Autoplay features.Usually, the danger is in the form of removable media. If an unproven media item is presented and immediately runs, there is a danger of infection.Many modern operating systems disable Auto-Run by default, lowering the risk of this type of worm. Just in case, make sure you have strong endpoint security in place so ...
Read MoreWhat is Harpooning? (How it Works, How to Prevent)
Harpooning is the act of a hacker gathering information from social media sites in order to mimic executives and target employees in their company for the purpose of obtaining sensitive personal data. The security specialists from Mimecast had polled hundreds of IT professionals and determined that a new wave of "whaling" − a type of phishing assault that especially targets C to top-level executives − had impacted firms.Difference between Phishing and CyberwhalingThe difference between phishing and cyberwhaling is almost identical to the difference between real-world fishing and whaling: A "harpoon" instead of a fishnet, targets an enormous target instead of ...
Read MoreWhat is Pharming Attack? (Process, How to Prevent)
