Anubis Ransomware
Posted: October 16, 2016
Threat Metric
The following fields listed on the Threat Meter containing a specific value, are explained in detail below:
Threat Level: The threat level scale goes from 1 to 10 where 10 is the highest level of severity and 1 is the lowest level of severity. Each specific level is relative to the threat's consistent assessed behaviors collected from SpyHunter's risk assessment model.
Detection Count: The collective number of confirmed and suspected cases of a particular malware threat. The detection count is calculated from infected PCs retrieved from diagnostic and scan log reports generated by SpyHunter.
Volume Count: Similar to the detection count, the Volume Count is specifically based on the number of confirmed and suspected threats infecting systems on a daily basis. High volume counts usually represent a popular threat but may or may not have infected a large number of systems. High detection count threats could lay dormant and have a low volume count. Criteria for Volume Count is relative to a daily detection count.
Trend Path: The Trend Path, utilizing an up arrow, down arrow or equal symbol, represents the level of recent movement of a particular threat. Up arrows represent an increase, down arrows represent a decline and the equal symbol represent no change to a threat's recent movement.
% Impact (Last 7 Days): This demonstrates a 7-day period change in the frequency of a malware threat infecting PCs. The percentage impact correlates directly to the current Trend Path to determine a rise or decline in the percentage.

EDA2-based ransomware is still being released, and the latest proof for this is the Anubis Ransomware, a cyber threat that uses the AES-256 encryption to lock files stored on the victim's computer. The Anubis Ransomware doesn't seem very sophisticated, and it appears that its author has not included any new features or modules that may make this EDA2-based threat more threatening than other EDA2 variants that malware researchers have already analyzed. Attacks that involve the Anubis Ransomware are fairly easy to recognize because this ransomware marks all encrypted files by adding the '.code' extension at the end of their names (e.g. 'document.txt' will become 'document.txt.code').
The ransom note that the Anubis Ransomware stores on the victim's desktop does not contain any information regarding the ransom fee or the payment method that needs to be used. The only instructions included tell users to contact 'support.code@aol.com' or 'support.code@india.com' if they want to receive decryption instructions. It is very likely that users who send a message to the attackers will be asked to pay a ransom fee via BitCoins in exchange for a decryption tool and instructions. Although this offer may tempt some users, we advise them not to send any money to the attackers since this doesn't guarantee that they'll get their data back. It is not uncommon for ransomware authors to stop responding to messages as soon as they receive the money, and there have been many cases in which ransomware operators asked for money even though they had no idea how to decrypt the files of their victims.
Previous EDA2 variants were successfully decrypted by malware experts, and there's a significant chance that this may happen with the Anubis Ransomware as well. That's why the best thing victims of the Anubis Ransomware can do is to use a reliable anti-malware software suite to erase the ransomware from their computers. The encrypted files should be preserved, as they will be required if a free decryption utility becomes available.
