Whois & Analysis for appriver.com

Ransomware is computer malware that installs covertly on a victim's device (e.g., computer, smartphone, wearable device) and that either mounts the cryptoviral extortion attack from cryptovirology that holds the victim's data hostage, or mounts a cryptovirology leakware attack that threatens to publish the victim's data, until a ransom is paid.

Simple ransomware may lock the system in a way which is not difficult for a knowledgeable person to reverse, and display a message requesting payment to unlock it.

More advanced malware encrypts the victim's files, making them inaccessible, and demands a ransom payment to decrypt them.

The ransomware may also encrypt the computer's Master File Table (MFT) or the entire hard drive.

Thus, ransomware is a denial-of-access attack that prevents computer users from accessing files since it is intractable to decrypt the files without the decryption key.

Ransomware attacks are typically carried out using a Trojan that has a payload disguised as a legitimate file.

Phishing is the attempt to obtain sensitive information such as usernames, passwords, and credit card details (and, indirectly, money), often for malicious reasons, by disguising as a trustworthy entity in an electronic communication.

The word is a neologism created as a homophone of fishing due to the similarity of using a bait in an attempt to catch a victim.

According to the 3rd Microsoft Computing Safer Index Report released in February 2014, the annual worldwide impact of phishing could be as high as $5 billion.
