According to Malwarebytes, which is a leading cloud security company, the top malware families have been named as CryptWall, WannaCry, MalwareBytes, SpyEye, and Gluon.
Read moreCryptWall malware has been around since 2013, and the newest version of it, dubbed MalwareVirus-7.
It’s currently installed on 1.4 million PCs, including around 4.5 million Windows PCs, and is spreading like wildfire.
MalwareBytes said it’s been able to crack the encryption on the WannaCrypt worm and decrypt the files it’s stealing.
The company says the malware can also be found on the Android phone and on some Macs.
SpyEye is more complex, but still able to infect the phone through a trojan called Gluons SpyEye.
Malicious apps on iOS, Android and Blackberry are also affected, but so far only one instance of the malware has reached the iPhone.
Maleficar has a longer list of malware variants on its website, but it says the most common variants are WannaCrack and MalwareFaker.
The most common variant for all malware is the WannabeCrack.
This is not the first time the malware family has been linked to ransomware.
Earlier this year, security researcher Ryan S. McInerney reported that the worm he created was actually a variant of the WanaCrypt worm, and it had been used by the notorious ransomware-for-hire group.
The WannaCroak worm was created by the same group and has since been linked back to the group.
This is the second ransomware variant to be linked to Wanna.
This time, the infection is a variant called Wanna-Cry.
The Wannacry worm is believed to have originated from China, though no one has yet been arrested in the case.
The main culprit behind the ransomware is not yet known, but Wanna Cry is being targeted by the group behind the infamous Ransomware.
It has been called the “most sophisticated ransomware of all time.”
Malwarebytes said it detected the worm’s code in March and said it is not part of any new threat.
It said it was still able, however, to crack some of the more complicated WannaCalls and MalewareBlocks, though this method only affected Windows PCs.
“The WanaCry ransomware is a complex worm that can be used to steal personal information and financial information, encrypt files, and perform data mining operations, among other tasks,” MalwareData said.
“Although some users may not notice any differences in the malware, we recommend that you pay attention to the information it is taking.”
The MalwareStats website has also provided a list of popular file-sharing services.
It said BitTorrent, file-hosting site The Pirate Bay, and a variety of other file-trading sites were affected by Wanna Crackers.
It is not clear when the malware infection started.
Malaysian police say that the virus, which was first spotted by security researchers at security firm Kaspersky Lab, was first detected on September 6.
They said it had already infected around 7,000 computers, but that number could be much higher as it was detected over a relatively short time.
Malteo, a company that offers anti-virus software for PC and mobile devices, said it has detected the malware and it has been removed.
MalwareAnalysis has also been able in the past to detect the malware.
“This is a new and evolving threat, but we have been able find and remove it before it could spread,” Malteo said in a statement.
