Researchers at IT security company Trend Micro say warnings that the Uiwix ransomware could be a more dangerous version of WannaCry might be inaccurate, according to a new report.

Cybersecurity experts say this piece of malware had an especially malicious quality. Mark Nunnikhoven is vice president of cloud research at the security software company Trend Micro.

The Zero Day Initiative (ZDI), which organizes Pwn2Own, published six advisories on Wednesday for each of the security holes fixed by Microsoft.

The malware, called Persirai, has been found infecting Chinese-made wireless cameras since last month, security firm Trend Micro said on Tuesday. The malware does so by exploiting flaws in the cameras that a security researcher reported back in March.

"The industrial robot – it's not ready for the world it's living in," said Mark Nunnikhoven, vice president of cloud research at Trend Micro. "The reality is these things are being connected in more and more places. There are a lot of attacks that could happen in that environment."
