Cyberspies Are Using Leaked NSA Hacking Tools to Spy On Hotels Guests

An infamous Russian-linked cyber-espionage group has been found re-using the same leaked NSA hacking tool that was deployed in the WannaCry and NotPetya outbreaks—this time to target Wi-Fi networks to spy on hotel guests in several European countries.
Security researchers at FireEye have uncovered an ongoing campaign that remotely steals credentials from high-value guests using Wi-Fi networks at European hotels and attributed it to the Fancy Bearhacking group.
Fancy Bear—also known as APT28, Sofacy, Sednit, and Pawn Storm—has been operating since at least 2007 and also been accused of hacking the Democratic National Committee (DNC) and Clinton Campaign in an attempt to influence the U.S. presidential election.The newly-discovered campaign is also exploiting the Windows SMB exploit (CVE-2017-0143), called EternalBlue, which was one of many exploits allegedly used by the NSA for surveillance and leaked by the Shadow Brokers in April.
EternalBlue is a security vulnerability which leverages a version of Windows’ Server Message Block (SMB) version 1 networking protocol to laterally spread across networks and also allowed the WannaCry and Petya ransomware to spread across the world quickly.
Since the EternalBlue code is available for anyone to use, cyber criminals are widely trying to use the exploit to make their malware more powerful.
Just last week, a new version of credential stealing TrickBot banking Trojan was found leveraging SMB to spread locally across networks, though the trojan was not leveraging EternalBlue at that time.
However, researchers have now found someone deploying the exploit to upgrade their attack.

“To spread through the hospitality company’s network, APT28 used a version of the EternalBlue SMB exploit,” FireEye researchers write. “This is the first time we have seen APT28 incorporate this exploit into their intrusions.”

Researchers have seen ongoing attacks targeting a number of companies in the hospitality sector, including hotels in at least seven countries in Europe and one Middle Eastern country.

Here’s How the Attack is Carried Out

The attacks began with a spear phishing email sent to one of the hotel employees. The email contains a malicious document named “Hotel_Reservation_Form.doc,” which uses macros to decode and deploy GameFish, malware known to be used by .
Once installed on the targeted hotel’s network, GameFish uses the EternalBlue SMB exploit to laterally spread across the hotel network and find systems that control both guest and internal Wi-Fi networks.

Once under control, the malware deploys Responder, an open source penetration testing tool created by Laurent Gaffie of SpiderLabs, for NetBIOS Name Service (NBT-NS) poisoning in order to steal credentials sent over the wireless network.

While the hacking group carried out the attack against the hotel network, researchers believe that the group could also directly target “hotel guests of interest”—generally business and government personnel who travel in a foreign country.
The researchers revealed one such incident that occurred in 2016 where Fancy Bear accessed the computer and Outlook Web Access (OWA) account of a guest staying at a hotel in Europe, 12 hours after victim connected to the hotel’s Wi-Fi network.
This is not the only attack that apparently aimed at guests of hotels. South Korea-nexus Fallout Team (also known as DarkHotel) has previously carried out such attacks against Asian hotels to steal information from senior executives from large global companies during their business trips.
Duqu 2.0 malware also found targeting the WiFi networks of European hotels used by participants in the Iranian nuclear negotiations. Also, high-profile people visiting Russia and China may have their laptops and other electronic devices accessed.
The easiest way to protect yourself is to avoid connecting to hotel Wi-Fi networks or any other public or untrusted networks, and instead, use your mobile device hotspot to get access to the Internet.

Information Security - InfoSec - Cyber Security - Firewall Support Providers Company in India

 

What is Firewall? A Firewall is a network security device that monitors and filters incoming and outgoing network traffic based on an organization's previously established security policies. At its most basic, a firewall is essentially the barrier that sits between a private internal network and the public Internet.

 

Secure your network at the gateway against threats such as intrusions, Viruses, Spyware, Worms, Trojans, Adware, Keyloggers, Malicious Mobile Code (MMC), and other dangerous applications for total protection in a convenient, affordable subscription-based service. Modern threats like web-based malware attacks, targeted attacks, application-layer attacks, and more have had a significantly negative effect on the threat landscape. In fact, more than 80% of all new malware and intrusion attempts are exploiting weaknesses in applications, as opposed to weaknesses in networking components and services. Stateful firewalls with simple packet filtering capabilities were efficient blocking unwanted applications as most applications met the port-protocol expectations. Administrators could promptly prevent an unsafe application from being accessed by users by blocking the associated ports and protocols.
