Some variants of Jigsaw ransomware are now relaying payment instructions to their victims via a live chat feature. Researchers at Trend Micro observed some variants of the crypto-malware sporting something new: a new lockscreen with a link to a chat feature through which the ransomware authors can communicate their payment demands to victims in real-time. Jigsaw demands $150 in exchange for the ransom key. The ransomware is not using its own chat client, but instead it is using onWebChat, a publicly available chat feature.”]
