This has led to millions of dollars in damages due primarily to ransomware worms. Unfortunately, despite the patch being available for more than 2 years, there are still reportedly around a million machines connected to the internet that remain vulnerable. The Equation Groups choice of prefixing their collection of SMBv1 exploits with the name Eternal turned out to be more than apt since the vulnerabilities they take advantage of are so widespread they will be with us for a long time to come. may have information that would be of interest to you. | antivirus signatures that detect Dirty COW could be developed. Anyone who thinks that security products alone offer true security is settling for the illusion of security. A nine-year-old critical vulnerability has been discovered in virtually all versions of the Linux operating system and is actively being exploited in the wild. The bug was introduced very recently, in the decompression routines for SMBv3 data payloads. CVE and the CVE logo are registered trademarks of The MITRE Corporation. The function then called SrvNetAllocateBuffer to allocate the buffer at size 0x63 (99) bytes.

Further work after the initial Shadow Brokers dump resulted in a potentially even more potent variant known as EternalRocks, which utilized up to 7 exploits. All of them have also been covered for the IBM Hardware Management Console. [37] Comparatively, the WannaCry ransomware program that infected 230,000 computers in May 2017 only uses two NSA exploits, making researchers believe EternalRocks to be significantly more dangerous. The vulnerability was named BlueKeep by computer security expert Kevin Beaumont on Twitter. Regardless if the target or host is successfully exploited, this would grant the attacker the ability to execute arbitrary code.
