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:	73

The OopsLocker Ransomware is a Trojan that blocks your files by enciphering them with an AES and RSA encryption combination. Having previous backups is the simplest way of recovering your data from such attacks efficiently, and malware experts rate this threat as being not vulnerable to free decryptors currently. Use anti-malware products to block or remove the OopsLocker Ransomware, whose campaign may be targeting corporate users preferentially.

When a Simple 'Oops' isn't as Accidental as One might Think

Even most of the independent Trojans using encryption as a part of their payloads tend to attack nothing more than the most generic types of data: text documents, pictures, archives, or the output of default Windows products. It's only rarely that malware experts see threats like the OopsLocker Ransomware: a Trojan designed from the ground up for compromising corporate sector-based targets and for-profit company servers. Both this Trojan's file-locking attacks and anti-security features are of greatest concern to victims of these types, although recreational PC users aren't fully immune.

The OopsLocker Ransomware begins its attacks similar to other threats of its kind: by creating a custom ID for the system and scanning for files to block. Besides targeting content related to the Microsoft Office programs, the OopsLocker Ransomware also encodes local backups, SQL databases, Mac resource files, and other, specialized data types. In total, the Trojan blocks just over forty types of content while also appending their names with '.oops' extensions for identification.

Malware experts also can confirm the OopsLocker Ransomware for terminating other programs, particularly ones related to SQL database and Microsoft server management. Previous threats with similar payloads sometimes use similar attacks, but, instead, for disabling security-related programs like Task Manager.

Keeping Your Files out of a Weekly Extortion Schedule

The OopsLocker Ransomware's authors are using pop-ups to provide various information on paying their ransom for the decryption key, the input of which is necessary for gaining access to the OopsLocker Ransomware's decryption feature. Malware experts are rating the OopsLocker Ransomware's encryption method, which uses a combination of the AES-256 and RSA-1024, as being secure, which makes reverting to your backups the best non-premium method for data recovery. Otherwise, the OopsLocker Ransomware's fees will continue rising on a weekly basis, until the victim takes the risk of paying.

There are several exploits con artists may use for installing threats like the OopsLocker Ransomware onto corporate systems:

Brute-force-based hacking tools can make numerous login attempts to crack weak passwords (such as '1234' or 'admin'), which lets threat actors install the Trojan manually.
Disguised e-mail messages can carry either attachments or website links with content suitable for dropping the OopsLocker Ransomware, such as a macro-based drive-by-download attack.
Exploit kits with hosting on hacked or corrupted sites can load through your Web browser automatically and install arbitrary software.

Anti-malware programs can block all of these infection methods, except for ones related to poor password use, and prevent any encryption damages by deleting the OopsLocker Ransomware automatically. Otherwise, workers can back up their work to remote storage regularly and abide by secure password guidelines.

The OopsLocker Ransomware is a Trojan that's being sent to the same targets holding some of the greatest amounts of wealth for extorting. Even global businesses not staying diligent in their Web security duties could find themselves paying an illicit toll to this Trojan's campaign if they want to maintain possession of their files.
