Ladon ransomware – a cyber infection that locks files and demands a ransom in Bitcoins
Ladon is a crypto-ransomware virus that uses AES encryption algorithm to lock personal data on a targeted PC.Successful unravel of cipher ends up with most of the file types inaccessible due to the .ladon file extension. The victim is provided with a personal ID, which can be found on a READ_ME.txt or READ_ME.html ransom note positioned on the desktop. The amount of the redemption varies from $200 to $500.

Ladon ransomware is a typical representative of its family of cyber infections. It is disseminated via unprotected Remote Desktop Services (RDS), spam email attachment, fake software updates, and similar illicit means. Upon revelation of a payload, the virus runs Command Prompt scrips to root deeply into OS and then enabled the AES-256 cipher to encrypt victim's files.

Experts speculate that Russian hackers are responsible for the development and distribution of Ladon ransomware. Despite the fact that a hybrid analysis revealed the virus being distributed from the USA, once installed on the system it searches for a Russian language locale. In case of detection, it disables the encryption process and generates a notification containing several Russian swear words.
Anyway, do not fall for paying the ransom. It's not yet clear whether the virus deletes Volume Shadow Copies and System Restore Points, so you may try to decrypt files encrypted by Ladon ransomware with the help of third-party software. Paying the ransom is not recommended because you can lose your money for nothing. Hackers often ignore victims and leave them without a decryptor even if they pay the ransom.

If you are already using one, update it before running a scan to renew the antivirus definitions. Upon successful Ladon removal, try decryption methods listed at the end of this post.
Ransomware distribution methods
This ransomware does not differ from the rest of the others regarding distribution. Its developers rely on malicious spam emails and fake software updates in particular. Nevertheless, it can also spread via unprotected Remote Desktop Services, phishing sites, and other means.
There's no hundred percent protection from ransomware attacks. Nevertheless, virukset.fi team there are two things that you should mind to minimize the risk of getting your PC infected. First of all, keep your anti-virus enabled and made sure it has a real-time protection feature. Besides, update it regularly.
Secondly, propagate proper web browsing behavior.

Choose a proper web browser and improve your safety with a VPN tool
Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.
Lost your files? Use data recovery software
While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.
To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
