Recently, The Sangfor Security Team identified a new GlobeImposter ransomware strain, naming it Globelmposter of Olympian Gods 2.0. Currently, several companies have suffered attacked and experienced a great many losses.

We found several variants with the following extensions appended to encrypted files: Hermes865, Hades865 and Apollon865.

Sangfor identified the first strain of GlobeImposter of Olympian Gods in July 2019, finding that first encrypted files were appended with the extension .ares666. In the subsequent two months, as the first version spread, companies and organizations in the manufacturing, education and business verticals suffered attacks by the following variants: Zeus666, Poseidon666, Apollo666, Artemis666, Ares666, Aphrodite666, Dionysus666, Persephone666, Hephaestus666, Hades666, Demeter666 and Hera666.

Based on the wide-spread first version of GlobeImposter, the attackers developed a second version and changed appended extensions to those of Greek God + 865, like Hermes865, Hades865 and Apollon865. The file type was changed from TXT file to EXE to enable auto-startup.

After analyzing the captured samples, Sangfor found that it is nearlly identical to the first version in code structure.
After launch, the virus will first create a note file (HOW TO BACK YOUR FILES.exe) and then disable the family group and then Windows defender.

Finally, the virus executes command through CMD to delete the RDP connection and system logs and delete itself.

Currently there is no decryption tool for victims. You may isolate infected hosts and disconnect them from network.

We recommend performing a virus scan and removal as soon as possible.

The Sangfor Security Team recommends proactive protection, as there is no way to decrypt the files encrypted by majority of ransom viruses.
1. Fix the vulnerability quickly by installing the corresponding patch on the host.
2. Back up critical data files regularly to other hosts or storage devices.
3. Do not click on any email attachment from unknown sources and do not download any software from untrusted websites.
4. Disable unnecessary file sharing.
5. Strengthen your computer password and do not use the same passwords for multiple computers to avoid compromising a series of computers.
