How to remove C3RB3R Ransomware and decrypt .LOCK3D files

0
C3RB3R is a variant of the Cerber Ransomware, a type of malware designed to encrypt data and demand ransoms for its decryption. Ransomware typically renames encrypted files, and C3RB3R is no exception. It adds the .LOCK3D extension (with the capital letter "O") or .L0CK3D (with a zero "0") to filenames. For example, a file initially named 1.jpg would appear as either 1.jpg.LOCK3D or 1.jpg.L0CK3D following encryption. The encryption method used by C3RB3R is not explicitly mentioned in the search results, but it's safe to assume that it uses a strong encryption algorithm, as is common with most ransomware. Once the encryption process is completed, C3RB3R drops a ransom-demanding message titled read-me3.txt; the number in the filename may vary. The ransom note warns the victim against deleting the text file and informs them that the inaccessible files have been encrypted. The only method of recovering the data is by purchasing the decryption software from the attackers. The ransom is 0.085000 BTC (Bitcoin cryptocurrency), but if it is not paid within five days, the sum will increase to 0.170000 BTC.

How to remove Jzie Ransomware and decrypt .jzie files

0
Jzie Ransomware is a variant of the Djvu ransomware family, which encrypts files on the victim's computer and appends the .jzie extension to the filenames. The ransomware generates a ransom note in a file named _readme.txt that demands payment for the decryption of the affected files. Jzie ransomware is typically distributed through malicious email attachments, fake software cracks, or by exploiting vulnerabilities in the operating system and installed programs. Jzie ransomware uses the Salsa20 encryption algorithm to encrypt files. After encrypting the files, it creates a ransom note in every folder containing encrypted files. The ransom note states that the victim can recover all files, including pictures, databases, documents, and other essential data, by paying a ransom amount ranging from $490 to $980.

How to remove Yzqe Ransomware and decrypt .yzqe files

0
Yzqe Ransomware is a file-encrypting virus infection that restricts access to data such as documents, images, and videos by encrypting files with the .yzqe extension. It is a variant of the notorious STOP/DJVU ransomware family. Once the files are encrypted, they are rendered inaccessible, and the ransomware drops a ransom note named _readme.txt on the desktop. The note contains instructions to visit a payment website and submit payment in Bitcoin cryptocurrency in exchange for the decryption key, which can allegedly restore access to encrypted files. The Yzqe Ransomware uses the Salsa20 encryption algorithm, which is almost impossible to "hack" due to the large key length and the vast amount of possible keys. The ransomware makes a copy of your file, removes the original one, encrypts the copy, and leaves it instead of the removed original.

How to stop “Funds For Transfer” e-mail spam

0
Funds For Transfer email scams are a type of phishing scam that aims to deceive recipients into sending money or providing sensitive information to scammers. These scams often involve a seemingly legitimate email that claims the recipient is entitled to a large sum of money, usually in the form of an inheritance, lottery winnings, or a contract payment. The scammers then attempt to extract money or personal information from the victim, often by requesting payment for fake administration fees or claiming that an advance payment is required to receive the full amount. Spam campaigns can infect computers through various methods, including: malicious attachments, malicious links, social engineering.

How to remove Yzoo Ransomware and decrypt .yzoo files

0
Yzoo Ransomware is a file-encrypting malware that belongs to the STOP/DJVU ransomware family. It restricts access to data by encrypting files with the .yzoo extension and then demands a ransom in the form of Bitcoin cryptocurrency in exchange for a decryption key to restore access to the encrypted files. Yzoo Ransomware targets various file types, such as documents, images, videos, and more. It encrypts these files using the Salsa20 encryption algorithm, rendering them inaccessible. After encrypting the files, Yzoo ransomware drops a ransom note named _readme.txt on the desktop and in every folder containing encrypted files. The ransom note provides instructions on how to contact the attackers and pay the ransom, which ranges from $490 to $980 in Bitcoin. The attackers use the email addresses support@freshmail.top and datarestorehelp@airmail.cc for communication.

How to remove Yzaq Ransomware and decrypt .yzaq files

0
Yzaq Ransomware is a type of malicious software designed to extort money from users by encrypting files on their computers. It is a member of the STOP/Djvu ransomware family and uses the Salsa20 encryption mechanism. This cipher has an enormous amount of possible decryption keys, making it virtually impossible to brute force them. The ransomware encrypts only the first 150KB of each file, which means that larger files, such as videos or music, may still be partially accessible. This ransomware is known for appending a specific extension, .yzaq, to each encrypted file and creating a ransom note named _readme.txt in various folders on the infected computer. This note typically informs the victim that their files have been encrypted and that they must pay a ransom to recover them. The ransom demanded can range from $490 to $980, usually in Bitcoins.

How to stop “KASIKORNBANK’ e-mail spam

0
KASIKORNBANK email spam refers to deceptive messages falsely claiming to be from KASIKORNBANK, a well-known financial institution in Thailand. Cybercriminals create these emails to entice recipients into compromising their computers by opening attached files containing malware, such as Agent Tesla. The risks of interacting with KASIKORNBANK email scams include the theft of sensitive information, unauthorized access to online accounts, and potential financial loss. There are various types of email spam campaigns related to KASIKORNBANK, including phishing, malware, and scareware. To protect yourself from KASIKORNBANK email scams, it is essential to stay informed about the latest cybersecurity threats and phishing techniques, employ trusted antivirus and anti-malware software, and ensure regular updates of your operating system, web browsers, and software applications.

How to remove BlackHatUP Ransomware and decrypt .BlackHatUP files

0
BlackHatUP is a variant of ransomware based on the Chaos ransomware. It encrypts data, appends its extension (.BlackHatUP) to filenames, generates a ransom note (read_it.txt), and changes the desktop wallpaper. For instance, it changes 1.jpg to 1.jpg.BlackHatUP, 2.png to 2.png.BlackHatUP, and so forth. BlackHatUP ransomware encrypts files using the AES algorithm. The AES key is then encrypted using the RSA public key contained in the configuration. The ransom note informs the victim that their attempt to execute an unauthorized .exe file has resulted in the permanent loss of their files. It offers a potential solution by suggesting that the files can be recovered if the victim pays a sum of 500 Indian Rupees (INR). The victim is directed to contact "BlackHatUP" on Telegram. To prevent future ransomware infections, it's crucial to maintain good cybersecurity practices. This includes regularly updating and patching software, using reliable security solutions, avoiding suspicious emails or websites, and regularly backing up important data.
