The new port targets Windows 10 x64 version , which was released in November and was code-named Threshold 2, still supported in the Windows Current Branch for Business. The RiskSense report goes into painstaking detail about the new attack, including a new payload replacing DoublePulsar, which Dillon said is cryptographically insecure and allows anyone to load secondary malware, which is what happened with WannaCry.
So, whoever wrote the original exploits did a lot of experimentation to find the best path to turn that crash into code execution. A lot of work went into this. Researchers have spotted notable code overlap between the Sunburst backdoor and a known Turla weapon. Researchers at Recorded Future report a rise in cracked Cobalt Strike and other open-source adversarial tools with easy-to-use interfaces.
Infosec Insider content is written by a trusted community of Threatpost cybersecurity subject matter experts. Note that this app doesn't exploit the vulnerability, it only detects it. You are provided with a live view of the scan, but at the end of it, a scan log is generated on your PC, so that you can use it in other circumstances, such as submitting it to security sites.
All in all, if you're afraid that your network PCs might be prone to EternalBlue attacks, you might want to give Eternal Blues a shot, as it can tell you whether you should be afraid or not in no time. It was essentially a way for Windows machines to talk to one another and other devices for remote services.
EternalBlue exploits SMBv1 vulnerabilities to insert malicious data packets and spread malware over the network. The exploit makes use of the way Microsoft Windows handles, or rather mishandles, specially crafted packets from malicious attackers.
All the attacker needs to do is send a maliciously-crafted packet to the target server , and, boom, the malware propagates and a cyberattack ensues.
But a key problem remains — for many versions of Windows, the software update must be installed in order to provide protection. It is this key problem that gives EternalBlue such a long shelf life — many people and even businesses fail to update their software regularly, leaving their operating systems unpatched and thus vulnerable to EternalBlue and other attacks. To this day, the number of unpatched vulnerable Windows systems remains in the millions. EternalBlue has been famously used to spread WannaCry and Petya ransomware.
But the exploit can be used to deploy any type of cyberattack, including cryptojacking and worm-like malware.
The NSA hack opened the door for any attacker to send a malicious packet to a vulnerable server that has not applied the patch to fix CVE The name says it all. WannaCry is the name of a worldwide ransomware attack made possible by the EternalBlue exploit.
See, even hackers have a comedic side. The WannaCry cyberattack began on May 12, and immediately had a global impact.
The ransomware spread at a rate of 10, devices per hour, infecting over , Windows PCs across countries in a single day. The NHS reported that thousands of appointments and operations were cancelled and that patients had to travel farther to accident and emergency departments due to the security breach.
Petya is another ransomware cyberattack that used the EternalBlue exploit to wreak havoc. Petya technically launched in early , before WannaCry, but to little fanfare and damage. By the way, we recommend you never, ever, ever, ever pay the ransom. Petya ransomware encrypts files and demands a ransom in Bitcoin to release them. Thanks to EternalBlue and the unfortunate success of WannaCry, Petya ransomware was given a second chance at destruction.
