Cerber3 Ransomware
Posted: September 1, 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 Cerber3 Ransomware is an update of the Cerber2 Ransomware, which bases itself on the original Cerber Ransomware. All of these Trojans use encryption encoding techniques to block your files and drop ransom notes recommending that you pay Bitcoins to get the attack's effects decoded. Victims have several options for protecting their data from this threat, all of which are superior to paying any ransoms, preferably after deleting the Cerber3 Ransomware with an anti-malware utility.
An Introduction to the World of Trojan Update Cycles
Version control, patches, and update management aren't the sole purview of legitimate products. Even illicit ones, such as threatening software, can benefit from releasing organized updates to old models. The Cerber Ransomware family is a good evidence of this fact particularly, with malware experts seeing its authors use update cycles to block previously-useful security countermeasures. The Cerber3 Ransomware is the latest release in this group.
The core feature of this family, hostile data encryption, persists with the Cerber3 Ransomware, which isolates files of relevant formats (documents, audio, images, archives, Web pages, or spreadsheets, for example). Besides encoding them with a potentially unbreakable cipher, the Cerber3 Ransomware also renames them according to a new format specific to this version of its family, which includes a custom extension ('.the Cerber3'). Readers who remember the original names of this family's HTML and TXT ransom notes also may note that the Cerber3 Ransomware uses new names for these components, although the contents are the same essentially.
Like the Cerber Ransomware or the Cerber2 Ransomware, the Cerber3 Ransomware asks for Bitcoin payments in exchange for decrypting your data. Malware experts do emphasize that the PC security sector has had reasonable success with providing free decryptors for this family, although, as a new update, the Cerber3 Ransomware may have changed its encryption technique to require the release of new tools sufficiently.
Keeping Your Security from Being Dated against the Latest in Trojan Warfare
Arguably, being able to reverse a the Cerber3 Ransomware's full payload is less important than preventing the infection's occurrence. Taking adequate protection measures, such as using strong passwords, disabling exploitable browser content, and scanning any content that's likely of being compromised (such as invoices found in e-mail messages) can remove most infection vectors for the Cerber3 Ransomware and other threats of its classification. Backups also can give you recovery solutions that are independent of the decryption resources that the PC security strives to provide.
Although many of the Cerber3 Ransomware's changes are aesthetic, malware analysts also saw some changes in its network communications behavior with reduced UDP activity. Victims should stay aware that Trojans may change from visually-identical ancestors in ways that may not be obvious substantially, but can have a profound impact on their ability to cause harm.
Professionally-developed anti-malware solutions should experience few issues with detecting or deleting the Cerber3 Ransomware. However, like any update to past threat, the Cerber3 Ransomware may have other surprises in store for the digital world.
