Your Wi-Fi router, sitting in the corner of your home accumulating dust and unpatched security flaws, provides an attractive target for hackers. Including, according to a new WikiLeaks release, the CIA. On Thursday, WikiLeaks published a detailed a set of descriptions and documentation for the CIA's router-hacking toolkit. It's the latest drip in the, and it hints at how the agency leverages vulnerabilities in common routers sold by companies including D-Link and Linksys.
The techniques range from hacking network passwords to rewriting device firmware to remotely monitor the traffic that flows across a target's network. After reading up on them, you may find yourself itching to update your own long-neglected access point. Inside Vault 7. Presonus studio one crack torrent. Routers make an appealing entry point for hackers, the CIA included, in part because most of them offer no easily accessible interface or performance giveaways when they've been compromised. 'There’s no sign to tell you whether your router is hacked or not—you’re just on the internet as normal,' says Matthew Hickey, a security researcher and founder of the firm Hacker House, who's analyzed the documents.
'The only thing is that everything you’re doing on the internet is going through the CIA.' According to the leaked documentation, the CIA's router-hacking killchain seems to start with a tool called Claymore, which can scan a network to identify devices and then launch the CIA's router-hacking exploits. The leaked files cite two specific exploits, named Tomato and Surfside.

Tomato appears to target vulnerabilities in at least two routers sold by D-Link and Linksys, and is designed to steal those devices' administrative passwords. The files also note that at least two other routers sold by Linksys could be targeted with Tomato after a few more 'manweeks' of development. The files don't explain Surfside in any detail, or exactly how the Tomato exploit works, though the documentation hints that it may abuse a protocol called UPNP that security researchers have.
It's not clear if the vulnerabilities that the exploits attack still exist in devices, or if the manufacturers have fixed them, given that WikiLeaks' Vault 7 files appear to date to early 2016 at the latest. (Neither D-Link nor Linksys responded immediately to a request for comment.) Even if they've made a patch available, though, the difficulty of updating router firmware means vulnerabilities often go unaddressed at the consumer level for years. Hickey also notes that the default admin password often resides printed on a sticker on the back on the router; for models on which Tomato or Surfside don't work, physical access could. With those credentials, a CIA hacker can then install their own custom firmware, which it calls Flytrap, on a victim's router. That malicious firmware can monitor the target's browsing, strip the SSL encryption from web links they click, and even inject other exploits into their traffic, designed to offer access directly to the target's PC or phone. Yet another piece of software, called CherryTree, serves as a command-and-control system for those hacked routers, allowing operators to monitor and update the infected network devices from a browser-based interface called CherryWeb. 'Everything you’re doing on the internet is going through the CIA.'
—Matthew Hickey, Hacker House Given the general insecurity of the average home router, it shouldn't come as a surprise that one of the world's most well-resourced spy agencies has exploited them for surveillance. But the details of those hacking tools should, if nothing else, serve as a reminder to, as frustrating a process as that may be.
Hacker House's Hickey says that if users stay vigilant in keeping their router updated, there's no direct evidence in the CIA leak that their router would be vulnerable to the agency's spying. But given that most users don't frequently update their routers, and consumer antivirus software doesn't track router malware either, WikiLeaks' release demonstrates just how much of a hacking bonanza the world's Wi-Fi access points may offer to capable hackers. 'Almost every home has a wireless router, and we don't have many tools to check what’s going on on those devices,' Hickey says. 'So it's quite a stealthy way to get malware into someone’s home.'
Security researchers from Cisco said today that they've detected a giant botnet of hacked routers that appears to be preparing for a cyber-attack on Ukraine. Researchers say the botnet has been created by infecting home routers with a new malware strain named VPNFilter. This malware strain is incredibly complex when compared to other IoT malware, and comes with support for boot persistence (the second IoT/router malware to do so), scanning for SCADA components, and a firmware wiper/destructive function to incapacitate affected devices. Russia is most likely preparing a cyber-attack on Ukraine Cisco says it found code overlap with BlackEnergy, a malware strain that has been used to cripple Ukraine's power grid in the winter of 2015 and 2016.
The US Department of Homeland Security has as the creators of the BlackEnergy malware and the perpetrators of the 2015 and 2016 Ukraine power grid attacks. Several countries have also of launching the NotPetya ransomware attack, which was also initially aimed at Ukraine.
While no officials accusations have been made, many also believe Russia launched the Bad Rabbit ransomware, also mainly aimed at Ukrainian companies. For the cyber-attack that hit the opening ceremony of the 2018 Winter Olympic Games in South Korea with the after the International Olympic Committee has banned the country from the event. Now, security experts believe Russia may be preparing another attack on Ukraine, but this time using a botnet of infected routers. VPNFilter botnet comprises over 500,000 hacked devices Cisco says it spotted the VPNFilter malware on over 500,000 routers manufactured by Linksys, MikroTik, NETGEAR, and TP-Link, but also from QNAP NAS devices. Cisco says no zero-days were used to create this botnet, but just older public vulnerabilities.
Symantec says it spotted VPNFilter malware on the following devices: Linksys E1200 Linksys E2500 Linksys WRVS4400N Mikrotik RouterOS for Cloud Core Routers: Versions 1016, 1036, and 1072 Netgear DGN2200 Netgear R6400 Netgear R7000 Netgear R8000 Netgear WNR1000 Netgear WNR2000 QNAP TS251 QNAP TS439 Pro Other QNAP NAS devices running QTS software TP-Link R600VPN Signs of this botnet's existence go back as far as 2016, but researchers say botnet started an intense scanning activity in recent months, growing to a huge size. Infected devices were found across 54 countries, but Cisco says the botnet's creators have been focusing on infecting routers and IoT devices located in Ukraine in the past weeks, even creating a dedicated command-and-control server to manage these Ukrainian bots. It is unclear what their intentions are, but Cisco fears a new attack may be coming pretty soon, as the botnet is ramping up its operations. The most likely targets for a cyber-attack are Saturday, the date of the UEFA Champions League soccer final, set to take place this year in Ukraine's capital, Kiev. Another plausible date is Ukraine's Constitution Day, the date of last year's NotPetya cyber-attack. VPNFilter is a very complex strain of IoT malware Cisco experts aren't sounding the alarm on this malware strain for nothing.
The VPNFilter malware is one of the most complex IoT/router malware strains and capable of some pretty destructive behavior. For starters, the malware operates at three stages. The Stage One bot is the most lightweight and simple, as its only role is to infect the device and obtain boot persistence. Until a few weeks ago, no IoT malware strain had been capable of surviving device reboots, with the Hide and Seek botnet earlier this month. But according to a Symantec, users can remove the Stage One malware by performing a so-called 'hard reset,' also known as a reset to factory settings.
The Stage Two VPNFilter malware module does not survive device reboots but relies on the Stage One module to re-download it when the user reboots (and inadvertantly cleans) his device. This Stage Two module's main role is to support a plugin architecture for the State Three plugins.
Cisco says that until now it has spotted Stage Three plugins that can.
Author: Published April 24, 2017 8:55 pm in, Linksys is working on a firmware update for 10 security vulnerabilities affecting its “Smart” Wi-Fi series of routers. Tao Sauvage, a security consultant for IOActive, came across the flaws after reverse-engineering the firmware for the EA3500 Series, one of more than 20 Linksys Smart Wi-Fi router models which use the 802.
11AC standards. Sauvage and his friend Antide Petit discovered 10 bugs in total. Six of those are vulnerable to exploitation by an unauthenticated attacker. Linksys EA3500 Series UART connection. (Source: IOActive) The security holes break down as follows:. The elder scrolls oblivion psp iso.
An unauthenticated actor can exploit two of the flaws to create a denial of service (DoS) condition and thereby render the router unresponsive. Until the individual ceases their attack, an admin can’t access the router’s web interface and users can’t connect to the network. Attackers can bypass the authentication measures protecting the Common Gateway Interface ( CGI) scripts to collect information from the router. Vulnerable data includes the router’s firmware version, running processes, as well as all connected devices and their respective operating systems. It’s possible for an actor to execute commands with root privileges on the operating system of the router. The attacker can leverage this unintended functionality to create a backdoor or gain persistent access to the router. Here’s a list of the vulnerable models:.
EA2700. EA2750. EA3500. EA4500v3. EA6100. EA6200.
EA6300. EA6350v2. EA6350v3. EA6400. EA6500. EA6700. EA6900.
EA7300. EA7400. EA7500. EA8300.
EA8500. EA9200. EA9400. EA9500. WRT1200AC. WRT1900AC.
WRT1900ACS. WRT3200ACM To evaluate the impact of the vulnerabilities, Sauvage and Petit used Shodan to identify vulnerable devices exposed on the web. The two researchers what they discovered: “We found about 7,000 vulnerable devices exposed at the time of the search. It should be noted that this number does not take into account vulnerable devices protected by strict firewall rules or running behind another network appliance, which could still be compromised by attackers who have access to the individual or company’s internal network.” The majority (69 percent) of those affected devices identified by the researchers are located in the United States. IOActive notified Linksys of the flaws back in January 2017. Since then, the two firms have been coordinating responsible disclosure of the security holes.
For instance, IOActive has said it won’t release a technical write-up of the issues until Linksys publishes an update, which it says it’s working on in a. While admins await this fix, Linksys recommends they help protect their devices by enabling automatic updates, disabling Wi-Fi guest networks if they’re not in use, and changing the default administrator password. I can’t emphasize that last recommendation enough.
Not only is it a, but it will also help defend against malware like that compromises IoT devices by brute-forcing their default login credentials. If you are concerned about good security, do not look to Linksys. They have no commitment to maintain firmware updates for any known period of time and while their technical support is very nice, they have very limited expertise.
I recently purchased a WRT1900AC, had connections problems and found it was an older version that they are no longer updating. Fortunately, I was able to return it. Unless you can get open source firmware updates for a Linksys router, would seriously recommend replacing it. In any case, you could still repurpose it as a access point but, unless Linksys changes their support plans, would avoid relying on it as your primary router.
More CES 2016. Linksys has a long history of supporting alternative firmware going back to the famous mid-90s. After, however,. Ten years later, and line.
Now, most users just want to be able to plug in their Wi-Fi routers and go. But for people who want the most from their routers - from upping transmission power to running an OpenVPN server - is exactly what they need. DD-WRT now expands the third party firmware choices for the WRT series of routers beyond the current support via 's 'Chaos Calmer' release. With DD-WRT, developers can provide custom firmware solutions for commercial applications for the new Linksys WRT platform. 'With Linksys and Marvel working closely to improve the upstream support for the Marvel CPUs and Wi-Fi radios, DD-WRT can now provide stable and robust support for the modern WRT series of routers in our alternate firmware platform, building on what was started many years back with the first WRT,' said Peter Steinhauser, Co-CEO, DD-WRT in a statement.
