# [New Research: 'We Jumped the Air Gap' Through Power Lines](https://www.secureworld.io/industry-news/can-you-jump-air-gap)

Just a few weeks ago SecureWorld wrote about the likelihood that North Korea has the [ability to compromise air gapped networks](https://www.secureworld.io/industry-news/north-korea-capable-of-jumping-air-gap).

Now a research team at Ben Gurion University says it has jumped the air gap and removed data through power lines.

#### **Exfiltrating air-gapped data through power lines**

They called their test "[Power Hammer](https://arxiv.org/pdf/1804.04014.pdf)," and there are two different variants they tested successfully.

"We present two versions of the attack. In line level power-hammering the adversary taps the power cables feeding the transmitting computer. In phase level power-hammering the adversary taps the power lines at the phase level, in the main electrical service panel. Using a non-invasive tap, the attacker measures the emission conducted on the power cables. Based on the signal received, the transmitted data is demodulated and decoded back to a binary form."

#### **Researchers say there are 4 phases to this air gap attack:**

1. Infection mode
2. Receiver implantation
3. Data gathering
4. Data exfiltration

[Read their air gap compromise research paper here.](https://arxiv.org/pdf/1804.04014.pdf) And then you can decide what an attack like this could look like at your organization.
