WHAT IS PHOBOS RANSOMWARE?
We recover from all types of ransomware, however, some of the popular ransomware families we recover from are below.
Dharma’s text file contains a very short message stating that the victim’s computer is unprotected and that developers can solve this problem and restore the encrypted files. To receive help, victims must contact Dharma’s developers via an email address provided
Dharma is a new variant of Crysis – a high-risk ransomware-type virus. and part of the Crysis family
By far, its the most active type of ransomware with a new variant released weekly

Phobos is a ransomware-type malicious program that (like most programs of this type) encrypts data/locks files stored and keeps them in this state until a ransom is paid. Phobos renames all encrypted files by adding the “.phobos” and “.Phoneix” extension plus the victim’s unique ID and an email address. For example, “1.jpg” might be renamed to a filename such as “1.jpg.ID-63857777.[email@example.com].phobos. Phobos ransomware is similar to Dharma Ransomware
Locky has been active since early 2016 and has predominantly been delivered using spam emails, although the Nuclear and RIG exploit kits have also been used. This ransomware has been consistently updated, particularly with changes to the way encrypted files are appended, leading media reports to attribute different naming conventions to Locky versions, such as Zepto (named after the .zepto extension). Locky activity increased in December 2017 with the resumption of spam activity by the Necurs botnet, which delivered up to 47 million spam emails per day over the holiday period.
The WannaCry ransomware attack was a May 2017 worldwide cyberattack by the WannaCry ransomware cryptoworm, which targeted computers running the Microsoft Windows operating system by encrypting data and demanding ransom payments in the Bitcoin cryptocurrency. It propagated through EternalBlue, an exploit developed by the US National Security Agency (NSA) for older Windows systems
Petya is a family of encrypting ransomware that was first discovered in 2016. The malware targets Microsoft Windows-based systems, infecting the master boot record to execute a payload that encrypts a hard drive’s file system table and prevents Windows from booting. It subsequently demands that the user make a payment in Bitcoin in order to regain access to the system
Cerber has been frequently developed and distributed since its inception in February 2016, with at least six different versions of the malware developed. Significantly, Cerber is run using a RaaS model, making it a highly automated operation both for actors using the platform and for servicing ransom payments and distributing decryptors to victims. The ransomware typically uses spam email and drive-by-downloads for delivery and has been associated with the RIG and Magnitude exploit kits. Cerber encrypts victim files with a random four-letter extension. Cerber RaaS customers can alter the specific ransom demands, although average prices for unlocking files fall between $1000 and $2000.
Ryuk, a targeted and well-planned Ransomware, has attacked various organizations worldwide. So far the campaign has targeted several enterprises, while encrypting hundreds of PC, storage and data centres in each infected company.
While the ransomware’s technical capabilities are relatively low, at least three organizations in the US and worldwide were severely hit by the malware. Furthermore, some organizations paid an exceptionally large ransom in order to retrieve their files. Although the ransom amount itself varies among the victims (ranging between 15 BTC to 50 BTC) it has already netted the attackers over $640,000
Active since at least December 2015, SamSam has been used in targeted attacks against high-profile victims and large organizations in the United States, Europe and Asia. These include transport organizations, such as transit authorities, as well as the healthcare and education sectors. Unlike most variants that use phishing emails and exploit kits, SamSam exploits Internet-facing JBoss application servers, then harvests administrator credentials before self-propagating and infecting all the endpoints within a network. Each infected machine is held to ransom, with demands ranging from approximately $4,000 for one machine and $33,000 for all machines within a network. SamSam is believed to be operated by a group known as Gold Lowell.
First detected in January 2016, DMA Locker differs from traditional ransomware variants as it does not add a file extension to encrypted files, but instead adds an identifier to the file header. DMA Locker has been delivered through RDP as well as spam emails and the RIG exploit kit. Following a successful infection, the ransomware begins encrypting files if an Internet connection is available. However, if an internet connection is not available, the ransomware installs itself and waits for a connection to be established before encrypting files.
Crysis (aka Dharma / Phobos) is distributed via spam emails and the compromised RDP services. Several variants of the ransomware exist to date. The first had decryption keys publicly released, enabling decryption without payment; however, recent variants that encrypt files with .arena, .cobra and .dharma extensions do not currently have publicly available decryption keys. Crysis also has additional capabilities such as harvesting information from the victim machine to send remotely to a command and control server. This included collecting credentials, instant messaging applications, webcam, and browser information.
GANDCRAB is ransomware type program used by developers (cybercriminals) to encrypt data stored on victims’ computers and to keep it in that state until a ransom is paid. This program creates a ransom message and generates a random name for it. For example, “DSEWRBG-DECRYPT.txt”
