‘.locky File Extension’ Ransomware

Posted: February 16, 2016

Threat Metric

The Threat Meter is a malware assessment that SpywareRemove.com's research team is able to give every identifiable malware threat. Our Threat Meter includes several criteria based off of specific malware threats to value their severity, reach and volume. The Threat Meter is able to give you a numerical breakdown of each threat's initial Threat Level, Detection Count, Volume Count, Trend Path and Percentage Impact. The overall ranking of each threat in the Threat Meter is a basic breakdown of how all threats are ranked within our own extensive malware database. The scoring for each specific malware threat can be easily compared to other emerging threats to draw a contrast in its particular severity. The Threat Meter is a useful tool in the endeavor of seeking a solution to remove a threat or pursue additional analytical research for all types of computer users.

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.

Threat Level:	10/10
Infected PCs:	862

The '.locky File Extension' Ransomware is a Trojan that uses file encryption-based ransom schemes to extract money from its victims. Countering any file encryptor-based infection requires removing the threat before you take any other actions for restoring any data that might have been damaged by its payload. Besides using anti-malware tools for removing the '.locky File Extension' Ransomware, malware experts always recommend keeping multiple backups for quick and reliable recovery of any damaged files.

The Newest in File Lockdowns for Cash

The '.locky File Extension' Ransomware is a recent file encryptor with no known relatives. Its campaigns have been seen targeting various US companies and organizations through e-mail spam, with the messages disguising themselves as invoices. Opening Word document attachments launch a corrupted macro script, which, in turn, installs the '.locky File Extension' Ransomware. The '.locky File Extension' Ransomware then begins scanning the compromised PC without providing any initial symptoms of its activities.

The '.locky File Extension' Ransomware targets files according to their extension formats, including PDFs, MP3s, and most forms of text documents. Appropriate information is encrypted with a 128-bit AES algorithm, rearranging their structure with the intention of making other programs unable to read them. With its primary payload finished, the '.locky File Extension' Ransomware adds name changes for each file in question, swaps the victim's desktop image to a ransom instruction, and places a duplicate of these instructions on the hard drive in a TXT file.

The '.locky File Extension' Ransomware instructs victims to make payments through a TOR browser-accessed website for the purpose of restoring their files. There is, however, no guarantee of the '.locky File Extension' Ransomware's con artists abiding by their half of the transaction, and malware experts rarely recommend resorting to threat solutions that reward their perpetrators.

Unlocking the Mystery of Protecting Your PC

The '.locky File Extension' Ransomware scans all non-essential folders on local hard drives, doesn't require admin-level privileges, and also may access network-mapped folders that are visited by the PC user. This inclusion makes it particularly important for PC users to protect their data with secure storage methods that can't be overridden by the '.locky File Extension' Ransomware, such as cloud storage or USB devices. Because the '.locky File Extension' Ransomware's campaign is new, only a minority of PC security companies have developed identifying entries for either the '.locky File Extension' Ransomware or the Trojan dropper embedded in its e-mail document.

E-mail invoices are a common tactic used by delivering threats to NGOs, governments and businesses around the world. Always scan these files before opening them, and, if possible, verify the legitimacy of an unknown e-mail attachment before taking the risk of opening it. As in all similar attacks, malware experts can't recommend solutions other than removing the '.locky File Extension' Ransomware with an anti-malware product of your choice, no matter how important your data is to you.
