One Ransomware Description

The One Ransomware is a Trojan that can lock your files, display messages soliciting money for unlocking them or block your screen. You can reduce the long-term impact of a One Ransomware infection by backing up your media and taking standard precautions against infection vectors like e-mail attachments. Since other threats may be responsible for installing it, you should remove the One Ransomware with anti-malware programs able to detect other forms of threats and uninstall them simultaneously.

The Daily Catch of Trojans Washing onto Brazil's Shores

Since many nations around the world use it either as a dominant or secondary language, English is often preferable for threat actors needing to speak with their victims. Not every Trojan campaign operates under this principle, however. In particular, malware analysts often catch Trojans targeting South American regions like Brazil with Portuguese-specific communications. Modern-day examples of just such threatening software include the Cry9 Ransomware, the PayDay Ransomware, and, as of April, the One Ransomware.

Although the Trojan isn't likely of being an independent program without ties to preexisting threats, the One Ransomware's genealogy is unknown. Like other file-encrypting Trojans, the One Ransomware uses the standard practice of identifying an infected system via a unique code, encrypting the media on it, and displaying messages asking the victim to pay for the similarly-individualized decryption key. Some of the symptoms that malware analysts rate as being likely over the course of an infection include:

  • The One Ransomware may encrypt documents and similar formats of files with a cipher to stop you from opening them. Most Trojans also modify filenames to give the locked content identifying strings; in the One Ransomware's case, it appends the '.one' extension. The name modifications are separate from the encryption, which re-organizes the internal data of each file.
  • The One Ransomware creates a text note in Portuguese that delivers its brief ransom instructions. The One Ransomware includes the system's personalized key and the e-mail address to contact for negotiations, which, in most circumstances, involve transferring money in cryptocurrencies like Bitcoin.
  • Pop-ups and other alerts from the One Ransomware also may prevent you from opening other programs or using your desktop interface deliberately.

Throwing the One Ransomware Back out to the Wild

Although the distribution phase of this Trojan's campaign is active, malware researchers have found very limited sample sizes for the One Ransomware attacks. The Trojan could be installing itself with the help of other threats, like the RIG Exploit Kit. Otherwise, its installer may use misleading names, extensions, or icons to confuse you into infecting your PC through paths like e-mail attachments. No data is yet available on decrypting the One Ransomware's hostage files, although victims can circumvent similar Trojans with freely-downloadable decryption programs.

Almost all infection methods that the One Ransomware could use to compromise your PC also can be monitored and blocked by standard anti-malware practices and products. All users in need of additional guarantees that their data will be safe should back their work up daily to another drive or server not left in contact with the one at risk of infection. Isolate or remove the One Ransomware with an anti-malware program before taking further steps, and, if necessary, use standard security protocols to avoid screen-locking symptoms like pop-up windows.

Unless its numbers see a steep and unanticipated spike, the One Ransomware is most likely destined to be a footnote, compared to other threats in the black hat industry of file-encrypting Trojans. Furthermore, PC users who don't back up their files can find that even one, single infection is more than enough of trouble to cost more money than is comfortable.
