Russian spies have developed a new technique to breach high-value targets via Wi-Fi, using compromised laptops or devices as relay points. The "nearest neighbor attack" technique has been linked to Russia's APT28 hacking group and poses significant risks for organizations focused on Ukraine and other sensitive areas.
The "nearest neighbor attack" technique involves remotely hacking into a vulnerable network across the street from the intended target using a compromised laptop or device as a relay point.This technique allows hackers to breach a network without physical presence, making it harder to detect.Volexity researchers discovered that hackers used this technique to breach multiple networks in the same building, creating a "daisy-chained" sequence of breaches via Wi-Fi.The nearest neighbor attack is likely to be used in future cyber espionage operations against high-value targets like those focused on Ukraine.Organizations need to take proactive steps to protect themselves against emerging threats, including improving Wi-Fi security measures such as limiting range and introducing additional authentication security measures.
In a shocking revelation, cybersecurity researchers have uncovered a new and sophisticated technique employed by Russian hackers to breach high-value targets via Wi-Fi. The technique, dubbed "nearest neighbor attack," involves remotely hacking into a vulnerable network across the street from the intended target, using a compromised laptop or device as a relay point to gain access to the target's network.
The discovery was made by Volexity, a cybersecurity firm that tracks and investigates network breaches. According to the researchers, the hackers used this technique to breach the Wi-Fi network of an organization in Washington, D.C., which is focused on Ukraine. The breach was carried out just months before Russia's initial full-scale invasion of Ukraine in February 2022.
The nearest neighbor attack technique is a significant improvement over traditional close-access hacking methods employed by Russian hackers. In these methods, small teams of hackers are sent to the target location via plane or car, where they physically hack into the network using specialized equipment. However, this approach has been compromised in recent years due to increased security measures and international cooperation.
In contrast, the nearest neighbor attack technique allows hackers to breach a network from across the street, using a remotely compromised device as a relay point. This reduces the need for physical presence at the target location and makes it significantly harder to detect.
Volexity's researchers discovered that the hackers had used this technique to breach multiple networks in the same building, creating a "daisy-chained" sequence of breaches via Wi-Fi. The first breach was carried out by hacking into a user's account on a Wi-Fi access point in a conference room with external-facing windows. From there, the hackers moved on to compromise another network in the same building, and eventually reached the target organization.
The researchers believe that this technique is likely to be used in future cyber espionage operations, particularly against high-value targets such as those focused on Ukraine. "This is essentially a close-access op like they've done in the past, but without the close access," said John Hultquist, a threat intelligence expert who has tracked Russian hackers.
The discovery of this technique highlights the evolving nature of cyber espionage and the need for organizations to stay vigilant against emerging threats. As Volexity's researchers noted, "Wi-Fi security has to be ramped up a good bit." This includes measures such as limiting the range of Wi-Fi networks, changing network names to make them less obvious to potential intruders, and introducing additional authentication security measures.
In conclusion, the nearest neighbor attack technique represents a significant escalation in Russian hackers' ability to breach high-value targets via Wi-Fi. As cybersecurity researchers continue to uncover new techniques and tactics, it is essential for organizations to stay informed and take proactive steps to protect themselves against emerging threats.
