Ransomware is a sort of malware that can lock a network down or disable it until a ransom is paid. Last month, a Russian hacking group used ransomware to shut down the Colonial Pipeline, disrupting most of the East Coast's oil and gas supply. Last year, the amount of cryptocurrency extorted as a result of ransomware assaults increased by 311 percent. President Biden intends to bring up the subject of ransomware attacks with Russian President Vladimir Putin.
