In late March, Google reported that its Android phones were being targeted by a new ransomware called Krunker.
The company has since updated its software to fix the problem, but the trend is only getting worse.
In the meantime, there are now new threats like Krunker 2.0, a new type of ransomware with a new and more insidious target: mobile devices.
As of March 31, the ransomware was infecting more than 100,000 devices around the world, according to a blog post from the cybersecurity firm Kaspersky Lab.
That figure includes Android phones.
In addition, the malware has also been spreading through the internet and has infected more than 60,000 machines in the US, according the company.
The new wave is not the first time that ransomware has infected mobile devices, though.
Earlier this month, the US Treasury Department said that ransomware had infected more people’s computers than any other ransomware.
The Treasury Department, which works with the Federal Bureau of Investigation (FBI), has been investigating Krunker since February, when the malware first began cropping up on Android phones and tablets.
Kaspersk says that it has detected the malware in more than a thousand Android devices.
“The Kasperskey malware family is a new threat group that is primarily targeting mobile phones, but we believe it is also targeting some desktop computers,” Kasperska’s Peter Gutmann told the New York Times.
Krunker has been used as a Trojan horse for other ransomware strains that encrypt files and demand payment in bitcoins.
One such ransomware, CryptoLocker, has been dubbed the “King of Bitcoins.”
This is not a new phenomenon, as the KRunker family has been in the spotlight in the past.
Last year, Kasperskaya published a list of malware families that have been used to encrypt files, and the group also reported that ransomware samples were being generated by the KRocker family in the United States.
Kudos to Kasperski for alerting the FBI about the KR0rker ransomware.
