Ppvt Ransomware is harmful and dangerous file-encrypting infection that restricts access to data by encrypting files with the “.PPVT” extension. It is a variant of the notorious STOP/DJVU ransomware family. This ransomware targets images, documents, videos, and other important files on infected computers, encrypting them and appending the .ppvt extension to the filenames, rendering them inaccessible. Upon infection, the PPVT ransomware scans the computer for specific file types such as .doc, .docx, .xls, .pdf, and more. When these files are detected, the ransomware encrypts them and makes them inaccessible. The ransomware uses the Salsa20 encryption algorithm, which is a robust ciphering algorithm that provides an overwhelming amount of possible decryption keys. Once the Ppvt Ransomware has encrypted the files on your computer, it drops a ransom note named _readme.txt on the desktop. This note contains instructions on how to contact the authors of the ransomware and demands payment in Bitcoin cryptocurrency in exchange for the decryption key.

Ppvw Ransomware is a file-encrypting malware infection that restricts access to data such as documents, images, and videos by encrypting files with the .ppvw extension. It is a variant of the notorious STOP/DJVU ransomware family. The ransomware attempts to extort money from victims by asking for a "ransom", typically in the form of Bitcoin cryptocurrency, in exchange for access to data. When Ppvw Ransomware infects a computer, it scans for images, videos, and important productivity documents and files such as .doc, .docx, .xls, .pdf. When these files are detected, the ransomware encrypts them. Once the Ppvw Ransomware has encrypted the files on a computer, it displays a ransom note named _readme.txt on the desktop. The note contains instructions on how to contact the authors of the ransomware, typically via email addresses such as support@freshmail.top and datarestorehelp@airmail.cc.

Ppvs is a file-encrypting ransomware infection that restricts access to data (documents, images, videos) by encrypting files with the .ppvs extension. It is a variant of the notorious STOP/DJVU ransomware family. The ransomware attempts to extort money from victims by asking for a "ransom", typically in the form of Bitcoin cryptocurrency, in exchange for access to data. Upon infection, the Ppvs Ransomware scans the computer for images, videos, and important productivity documents and files such as .doc, .docx, .xls, .pdf. The Ppvs Ransomware uses a sophisticated encryption scheme that requires a decryption key and recovery program combination to decrypt the files. Once the Ppvs Ransomware has encrypted the files on your computer, it displays a _readme.txt file that contains the ransom note and instructions on how to contact the authors of this ransomware. The ransom note is typically dropped on the desktop of the infected computer.

Jarjets is a type of ransomware, a malicious software designed to block access to a computer system or files until a sum of money is paid. It was discovered during a routine investigation of new file submissions to the VirusTotal site. Once the Jarjets ransomware infects a system, it encrypts files and changes their filenames. The original titles are appended with a .Jarjets extension. For example, a file named 1.jpg would appear as 1.jpg.Jarjets, 2.png as 2.png.Jarjets, and so on. The specific encryption algorithm used by Jarjets is not explicitly mentioned in the search results, but ransomware typically uses complex encryption methods, often a combination of symmetric and asymmetric encryption. After the encryption process is completed, Jarjets ransomware creates a ransom note titled Jarjets_ReadMe.txt. This text file informs the victim that their files have been encrypted and urges them to contact the cyber criminals.

BlackDream Ransomware is a type of malware that encrypts data on a victim's computer and demands payment for its decryption. It was discovered by researchers while investigating new malware submissions to VirusTotal. The ransomware appends a unique ID, the cybercriminals' email address, and the .BlackDream extension to the filenames of encrypted files. For example, a file initially named 1.jpg would appear as 1.jpg.[G7H9L6ZA].[Blackdream01@zohomail.eu].BlackDream. After the encryption process is completed, a ransom note titled ReadME-Decrypt.txt is dropped. BlackDream ransomware uses an unspecified file encryption method. The note reassures the victim that their files have not been damaged but have been encrypted. It warns that seeking aid with recovery outside the attackers (i.e., using third-party tools or services) may render the data undecryptable. The note implies that decryption will require paying a ransom in Bitcoin cryptocurrency, although the exact sum is not specified.

The "You've Been Hacked!" email scam is a type of phishing attack where scammers send emails claiming to have stolen personal information from recipients. The scammers then demand payment, often in the form of Bitcoin, in return for not publishing the stolen details. These emails frequently claim that the scammers have stolen login credentials for payment systems, social networks, email accounts, and other sensitive data. However, these claims are typically false and are designed to scare the recipient into complying with the scammer's demands. Spam campaigns can infect computers in several ways. One common method is through phishing emails. These emails regularly appear to come from reputable companies and contain links or attachments that, when clicked or opened, can install harmful malware on the recipient's computer. Another common technique used by cybercriminals is creating malicious Office macros. These macros, which are typically enabled by default to run commands, can be used to execute malicious code and provide cybercriminals with a way to gain control of a computer.

"Your Account Was Hacked" is a type of email scam, also known as a spam campaign, used by cybercriminals to trick people into paying them. The scammers send an email claiming that the recipient's computer has been infected with a malicious program, allowing them to record a compromising video and steal personal data. The scammers then threaten to share the video if their demands are not met by a given deadline. However, these claims are false, and such emails should be ignored. There are two versions of this spam campaign, but they are essentially identical. The scammers claim to have hacked the user's email account and use the 'spoofing' method to forge email addresses, making the scam seem genuine. They also claim to have installed special software on adult video sites, which they allege the recipient visited.

Adobe Invoice email spam is a type of phishing scam where the spam email is disguised as an invoice detailing an Adobe subscription for a year. The email often includes a telephone number for "customer support" and a sum of 312.49 USD. However, this invoice is fake and is in no way associated with Adobe Inc. or any of its products/services. The goal of such schemes is to deceive victims into disclosing private data or making monetary transactions. Spam campaigns typically infect computers through malicious attachments or links embedded in the emails. These attachments usually carry trojans that are capable of stealing passwords, banking information, and other sensitive information. If a potential victim falls for the lure and opens the attachment, their computers get infected, and cybercriminals can collect a lot of sensitive information.
