UPnProxy – A Dubbed NSA Hacking Tool of EternalSilence Vulnerable to Attack 277,000 UPnP Enabled Routers
UPnProxy is alive and well. There are 277,000 devices, out of a pool of 3.5 million, running vulnerable implementations of UPnP. Of those, Akamai can confirm that more than 45,000 have been compromised in a widely distributed UPnP NAT injection campaign. These injections expose machines living behind the router to the Internet and appear to target the service ports used by SMB.
New research reveals that Universal Plug and Play (UPnP) implemented 277,000 Connected Devices are vulnerable to malicious proxy system UPnProxy , a dubbed EternalSilence NSA hacking tool arsenal.
UPnProxy is a feature that allows the devices on your network to discover each other and allow to access certain services. Often, this is used for streaming media between devices on a network.
Currently, a pool of 3.5 million connected devices are using UPnP and among these devices, more than 45,000 have been compromised in a widely distributed UPnP NAT injection campaign.
Attackers abusing the UPnP system and creating a malicious proxy system called UPnProxy that helps attacker s to reroute the original traffic landing into malicious services such as spam, phishing, click fraud, and DDoS.
It mainly affected the home routers that leads to infect with malware, ransomware and others infections.
Malicious UPnProxy initially discovered by researchers at Akamai and they have dubbed Eternal Silence which is derived from port mapping descriptions and the researchers believed that it leveraging the exploits from NSA Eternal family.
Earlier this year, Akamai researchers reported on how Universal Plug and Play (UPnProxy) was being abused by attackers to conceal traffic, creating a malicious proxy system we’ve called UPnProxy. Because UPnProxy can be leveraged to route an attacker’s traffic at will, there is a serious risk that this flaw can be leveraged in a number of attacks, including spam, phishing, click fraud, and DDoS.
Now, six months later, we’re seeing evidence that UPnProxy alive and well. Out of a potential victim pool of 3.5 million vulnerable devices, 277,000 of them are vulnerable to UPnProxy. Our scanning revealed at least 45,000 actively injected machines, those with the telltale routes already in their port mappings. These numbers are subject to change as the attackers continue to scan for new machines to compromise. While some of the campaigns observed in the original research have since disappeared, a new campaign of injections has been discovered.
In Akamai’s previous research, we highlighted the possibility that attackers could leverage UPnProxy to exploit systems living behind the compromised router. Unfortunately, data from this recent batch of injections suggests this is exactly what’s happening.
For home users, these attacks can lead to a number of complications, such as degraded service, malware infections, ransomware, and fraud. But for business users, these recent developments could mean systems that were never supposed to exist on the internet in the first place, could now be living there unknowingly, greatly increasing their chances of being compromised. Even more concerning, the services being exposed by this particular campaign have a history of exploitation related to crippling worms and ransomware campaigns targeting both Windows and Linux platforms.
Attack leveraging NSA’s Eternal family of exploits using this EternalSilence campaign which is confirmed by an observation of millions of successful injections attempting in order to expose the millions of SMB running services. In this case, 2 powerful NSA exploits, EternalBlue (CVE-2017-0144) and EternalRed (CVE-2017-7494) used by attackers and utilize the static ports (TCP/2048) in order to inject SMB port forwards.
Also, there will not be any administrative visibility of an injected router since its difficult to detect the malicious NAT injections. The best way to identify if a device is vulnerable or actively being leveraged for UPnProxying is to scan an end-point and audit it’s NAT table entries, Researchers said.
