An evolved version of the infamous NotCompatible Android malware has been uncovered stealing information from corporate networks.
Researchers at Lookout reported finding the new malware variant, warning it has several new advanced capabilities.
"NotCompatible.C has set a new bar for mobile malware sophistication and operational complexity," the firm said.
"The command infrastructure and communication perseveres and self-protects through redundancy and encryption, making it elusive and enduring. It's an earthworm with its tail cut off that regenerates and thrives."
NotCompatible is an Android malware that has been active since at least 2012. The malware targets smartphones and tablets using drive-by downloads and uses them as a launch point to spread through corporate networks.
Lookout said it is currently unknown exactly how many devices have been infected with NotCompatible, though the number is likely in the hundreds of thousands.
"Our investigation shows the possibility that a threat like this could expand to assist in attacks on corporate networks, a risk that should not be ignored," wrote Lookout's Tim Strazzere in a blog post.
"Lookout has thus far actively protected against NotCompatible on hundreds of thousands of devices in the US and around the world."
Mobile malware is an ongoing issue afflicting businesses of all sizes. Android has traditionally been the primary target of mobile malware, though researchers uncovered the first officially recorded case of iOS malware, codenamed Wirelurker, in November.
