Update September 2019. What is Hese virus? This article presents a step-by-step guide on how to remove Hese ransomware virus and how to attempt to recover .hese encrypted files.
Hese virus is a ransomware infection that is based on the code of the infamous STOP ransomware. When started on your computer Hese disrupts system security and encodes personal files. Encrypted files could be recognized by the extension .hese appended by the ransomware. At the end of the attack, Hese virus creates a ransom message that urges you to pay a ransom for the .hese files decryption. This message could be found in the _readnme.txt file which is typically placed on the desktop.

Hese Virus (STOP Ransomware) – Update September 2019
As reported by Michael Gillespie, the operators of STOP ransomware have altered its code in newer versions. These changes make the way the researcher decrypted files impossible, starting with .coharos, .gero, and .hese. Apparently, the cybercriminals started to utilize proper asymmetrical encryption, meaning the offline keys will no longer be valid for decryption after this release of the final keys Gillespie extracted.
The researcher is now working towards closing this decrypter, and continuing work on a new decrypter that will work only for the old versions of STOP (up to .carote), but with some caution. The new decrypter will completely replace STOPDecrypter once it’s released, and will work in a different way, the researcher said.
The first version of STOPDecrypter is designed to support specific offline IDs, so it may not be effective for all occasions of the various iterations of the ransomware.
Hese Virus (STOP Ransomware) – More About the Infection
Security researchers reported that the Hese virus is based on the code of one of the most popular ransomware families dubbedSTOP. The spread of Hese ransomware is happening with the help of spam emails, email attachments, hacked web pages, and corrupted freeware installers.
Since malspam (emails that deliver malicious code) enables hackers to spread their ransomware on a large scale, they usually rely on it for their distribution campaigns. Attackers usually embed the malicious code in files of well-known types and then attach these files to email messages. The emails usually state that the attached files are:
- Invoices coming from reputable sites, like PayPal, eBay, etc.
- Documents from that appear to be sent from your bank.
- An online order confirmation note.
- Receipt for a purchase.
Once activated on your system Hese virus creates a bunch of malicious files and places them in folders like %AppData% and %LocalAppData%. With the help of newly created malicious files the ransomware corrupts essential system settings and becomes able to encrypt target files.
For the encryption of target files Hese virus launches a built-in cipher module that is designed to scan selected folders for predefined types of files. Every time the module detects a target file, it utilizes a sophisticated cipher algorithm to transform its code. Unfortunately, the threat is likely to corrupt all files which store valuable information. Hence, encrypted may be:
- Audio files
- Video files
- Document files
- Image files
- Backup files
- Banking credentials, etc
Following encryption files cannot be opened. In addition, they have the extension .hese at the end of their names. In fact, the main goal of this ransomware is to blackmail you into paying a ransom to hackers. That’s why Hese drops a ransom message with instructions on how to complete the ransom payment process.
You should NOT under any circumstances pay any ransom sum to cybercriminals. This action does not guarantee the recovery of your .hese files.
