Zepto Ransomware
Posted: June 29, 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.

The Zepto Ransomware is a fork of the '.locky File Extension' Ransomware. Both of these threats are threatening file encryptors that sell decryption services paired with their encryption methods. Handling such threats preemptively with backups can keep your information from coming to any harm, while your anti-malware programs should be able to remove the Zepto Ransomware or identify its delivery vehicles, such as other Trojans.
The Trojan that Makes It Hard to Find What You Already Own
Ransoming digital data illegally may be about pressuring the PC users psychologically as much as it is about using sophisticated encoding algorithms. Although a majority of file encryption Trojans uses renaming methods that help victims identify the effects of the infection readily, others, like the Zepto Ransomware, take a harsher route. The Zepto Ransomware uses a unique renaming convention that may impede being able to identify the original contents of your files but makes it clear that an encryption-based attack has taken place.
As a new heir to the '.locky File Extension' Ransomware, the Zepto Ransomware is most likely sharing its infection vectors, which specialize in using crafted e-mail messages distributing threat installers via attachments. After being installed through the launched document or otherwise misrepresented file, the Zepto Ransomware scans your computer and encrypts data according to types specified by its author. No visible symptoms accompany the encryption process while it occurs.
Many Trojans similar to the Zepto Ransomware may rename the extensions of each piece of data or even the names of the directories that hold such information. Malware researchers find the Zepto Ransomware using a much more individualized renaming scheme that includes both a serial number for the infection and an additional code that's unique to each file. Finally, it appends a '.the Zepto' extension. The Trojan entirely overwrites the original contents of the names.
More File Terrorism for a Trifling Bitcoin Profit
The launch date for the Zepto Ransomware's campaign seems to date to late June of this year, although its ancestor, the '.locky File Extension' Ransomware, has been around for some months longer than that. Despite being a 'brand-new' threat, the Zepto Ransomware generates very traditional ransom messages that redirect all victims to a TOR anonymity browser-obfuscated Web page for taking payments. These transactions, most often conducted through potentially unsafe methods like Bitcoin, don't always provide the promised, working data retrieval feature, and malware experts observe decryptors failing entirely occasionally.
The misleading-endorsed methods of recovering from the Zepto Ransomware attacks may offer little hope, but even the most cursory of precautions can put your PC's information out of sight of this threat. PC owners making routine use of the remote backup technology, either via network servers or physical devices, can recover from the Zepto Ransomware attacks easily, and delete the original, damaged content. Publicly available decryptors for the Zepto Ransomware and other members of its family still are a subject of research in the PC security sector.
Equally viable is identifying the Zepto Ransomware or the Trojan installer of it before the threat can complete its payload. E-mail spam is the top distribution method, not only for the Zepto Ransomware but a clear majority of data encrypting Trojans. The value in responding to e-mail queries promptly always should weigh itself against the possible need to remove the Zepto Ransomware or other business sector-targeting threats from your system.
