Note that malware can only be distributed in this way if Trojans are already installed on computers. Trojans are malicious programs that can cause chain infections by installing other software of this kind. When users download and open (execute) the files, however, they inadvertently install malware.įake software updating tools cause damage by installing malware rather than updates/fixes for installed software, or by exploiting bugs/flaws of outdated software. These are used to distribute malicious files by disguising them as legitimate and regular. If the documents are opened with MS Office versions prior to 2010, however, the documents install malicious software automatically, since these older versions do not include "Protected View" mode.Įxamples of untrusted file and software download sources are Peer-to-Peer networks (torrent clients), free file hosting websites, freeware download sites, and unofficial web pages. Note that malicious MS Office documents can install malware only when users enable editing/content (macros commands). Cyber criminals usually attach a Microsoft Office document, archive file (ZIP, RAR), PDF document, executable file (.exe) or JavaScript file, and wait until recipients open it. Their main goal is to trick recipients into executing the file, which then infects the computer with malware. Using malspam, criminals send emails that have a malicious file attached, or include a website link designed to download a malicious file. Ransomware and other malware infections are commonly spread through malspam campaigns, untrusted file/software download sources, fake (third party) software updating tools, Trojans and unofficial software activation tools. More of examples of malware that is classified as ransomware are JJLF, 14x, and Coos. Victims can decrypt files with third party, free tool/without interference of cyber criminals only in rare cases when ransomware has bugs or flaws. Therefore, maintain backups on remote servers (such as Cloud) or unplugged storage devices. ![]() Main differences are size of ransom that victims are demanded to pay and cryptographic algorithm ( symmetric or asymmetric) that installed ransomware uses for data encryption. To summarize, victims of ransomware attacks cannot access/use encrypted files unless they decrypt them with valid decryption tools/keys held only by ransomware developers. Screenshot of a message encouraging users to pay a ransom to decrypt their compromised data: The only reliable way to recover files is to restore them from a backup.įurther encryption of any unaffected files can be prevented by uninstalling the ransomware - in this case, Hello (WickrMe) - however, already compromised files remain encrypted even after removal of the rogue software. Unfortunately, there are no third party tools that can decrypt files that are encrypted by Hello (WickrMe). Note that paying ransoms to ransomware developers does not guarantee that they will send decryption tools. To get instructions about how to pay for a decryption key and software, victims are instructed to contact ransomware developers via or by sending a message to the candietodd or kevindeloach user on Wickr Me messenger. The ransom message is placed in all folders that contain encrypted files. It also creates a ransom message within the " Readme!!!.txt" text file, which contains instructions about how to contact the developer. For example, " 1.jpg" is renamed to " 1.jpg.hello", " 2.jpg" to " 2.jpg.hello", and so on. Hello (WickrMe) ransomware encrypts files and appends the ".
