Indexsinas is the latest EternalBlue attack to go global. Researchers have estimated that there are over 1 million SMB servers accessible to anyone on the internet, and many are vulnerable to EternalBlue attacks. The software update that fixes EternalBlue’s vulnerabilities and exposures (named the MS17-010 patch) has one weakness: it needs to be installed by the user. But there are still many devices that haven’t received the vital security patch. Since then, most Microsoft devices have been patched - meaning the EternalBlue vulnerability has been fixed. The most infamous cyberattacks involving the EternalBlue exploit occurred in 2017. If EternalBlue is old, why should we worry? Today, most Microsoft machines are protected against EternalBlue, but many are still at risk. Once inside, malware can spread to all of the devices on the network and beyond.ĮternalBlue takes advantage of SMBv1 vulnerabilities.ĭespite Microsoft’s attempts to fix the vulnerability and protect users, hackers used this computer exploit to launch some of the largest cyberattacks in history. But SMBv1 contains bugs that let hackers send malicious data packets into the network. The Server Message Block version 1 network protocol helps computers share files with printers, ports, and other Windows machines. The EternalBlue exploit (also known as MS17-010) takes advantage of a flaw in a network file-sharing protocol in Microsoft computers called SMBv1.
