Sage Ransomware

The Sage Ransomware is a Trojan that encrypts your files so that you can't open them and, then, delivers instructions on paying its threat actors to get access to the decryptor. If not blocked by security software before its most visible symptoms appear, this threat may cause permanent file damage. Malware experts recommend having anti-malware tools for quarantining or removing the Sage Ransomware, and backups for recovering from worst-case scenarios.

The Flavor Your Files Don't Need

Just as legal businesses know that ease of use and consumer comfort affects spending habits, con artists also try their best to lubricate the act of transferring money. This repeating theme is one that malware analysts find in different threat campaigns expressing itself through attacks like timer-based warnings, such as the Sage Ransomware's pop-up. However, these strategies also have the support of causing real damage to the files on your computer.

Confirmation is underway for which infection methods the Sage Ransomware uses for installing itself, although the Trojan doesn't exhibit any traits that would let it spread without assistance from a third-party. Common exploits for spreading threats of the same category include spam e-mails disguising themselves as work documentation and manual attacks against network accounts with easily hacked passwords. Once the victim or threat actor installs it, the Sage Ransomware begins scanning for files that it can lock through an encryption cipher.

Malware analysts verified the Sage Ransomware targeting files including formats such as XLS spreadsheets and JPG images. After blocking these data types, which may or may not have their names modified, the Sage Ransomware displays two messages to its victims in a wallpaper image and an HTML pop-up.

This second message includes most of the Sage Ransomware's notable features through its Web infrastructure: detailed guidelines on how to pay Bitcoins, a live countdown, and warnings about failures to pay incurring increases in the ransom fee. Since the Sage Ransomware's decryption service requires a separate download, con artists may not provide it after taking their money necessarily, and the use of Bitcoins prevents the victim from canceling the payment.

Getting Rid of that Dash of the Sage

The Sage Ransomware uses a streamlined Web interface to tempt its victims into paying ransoms for potentially no file recovery, which is becoming increasingly common with file-encrypting Trojan campaigns run by experienced threat actors. Although malware experts discourage relying on local backups to nullify the damages of threats like the Sage Ransomware, most backups stored on non-local drives not directly accessible by the Trojan should be safe. To date, only a handful of Trojans are verifiable for targeting cloud services, and no threat can target any removable devices left detached until after you disinfect your PC.

Third parties in the PC security industry speculate that the Sage Ransomware may be the product of recycling from the code of the TeslaCrypt Ransomware project. While malware experts can't confirm this potential lead, victims are welcome to attempt using decryptors for that family, if no other file recovery options are practical. The use of decryption solutions never should impact the actual deletion of the Sage Ransomware beforehand through appropriate anti-malware tools.

Countdowns and escalating expenses are socially manipulative tools that both legal and illegal capitalistic ventures use for manipulating their customers. Failing to fall for upfront cons like the Sage Ransomware's pop-up is both a matter of questioning warnings from con artists and taking the right steps to keep your computer safe in advance.
