OhNo Ransomware Description
The OhNo! Ransomware is a threat that encrypts media on your PC to hold it hostage until you pay a ransom with the Monero crypto currency. It usually will use misleading file data to disguise itself as another program, with pop-ups and other symptoms appearing after it finishes locking your files. Because decryption for free has yet to be available, malware experts suggest that you back up your content and have anti-malware programs block or remove the OhNo! Ransomware in appropriate circumstances.
The File-Snatching 'Web Browser'
Fake freeware and shareware downloads are one of the most conventional methods of circulating Trojans and other sub-types of threatening software. Threat actors without any desire to compromise relatively secure targets, such as business sector entities or a government branch's networks, often rely on the victims downloading their misnamed software at random. Such attacks appear to be at the epicenter of the OhNo! Ransomware's campaign: a new brand of Trojan specializing in file-ransoming encryption.
The OhNo! Ransomware's executable describes itself as being the Chrome Web browser, a free Web-browsing program with a substantial user base. Although it has a more limited encryption whitelist than most Trojans of its kind, the OhNo! Ransomware does encipher the Windows profile's media folders, as well as the contents of the desktop, and the default Windows Downloads folder. It uses an AES-based cipher for blocking the victim's files, and malware experts find no immediate vulnerabilities for allowing a third-party to crack it.
All files that the OhNo! Ransomware locks will have appended '.OhNo!' extensions in their names. The Trojan swaps the desktop's wallpaper with a statue-themed image it includes in its payload additionally. It generates a Windows message box for displaying its ransoming message, which asks the user to pay Monero currency to decode and unlock their media.
Just Saying No to a Fake Browser
As the most popular Web-browsing application of the past few years, Chrome is equally favorable as a disguise for Trojans that use consensual download and install methods. Always go to an official website or download resources endorsed by one before trusting a download of a well-known product like Chrome, Firefox or Edge. Although most versions of the OhNo! Ransomware will have misleading names and file data, the Trojan has a minimum of defense against being identified by most brands of dedicated anti-malware software.
Delaying any response to the OhNo! Ransomware until symptoms are apparent can cause permanent damage to your documents and other files. Having secure backups can keep file-encrypting threats from taking your media hostage, and paying ransoms, cryptocurrency ones like Monero or Bitcoin particularly don't always provide access to a decryptor. Always disinfect your PC with anti-malware products that can remove the OhNo! Ransomware safely while also determining whether any other threats are arriving through the same infection vector.
The growth of technology also comes with downsides, such as letting remote attackers reach into your PC and collect your digital belongings potentially. Doing what you can to protect your files before a problem's arrival can cripple the profitability of campaigns like the OhNo! Ransomware's fake Chrome attacks.
