That allowed researchers to use Shodan to scan for port 10,000 on the SingTel routers and login as the devices Admin. Once in, researchers said attackers would not only be able to manipulate or snoop on network traffic, but also would have easy access to devices on the compromised network.
Routers are juicy targets for hackers to plant malware and cybercriminals to perpetrate DNS hijacking of unsecured WiFi routers.
Earlier this month, Anubhav identified 5,000 Datacom routers with no Telnet password tied to a Brazilian ISP, Oi Internet. Last week, the FBI warned of malware called VPNFilter that it said had infected 500,000 routers tied to brands Linksys, MikroTik, NETGEAR and TP-Link. Also last week, Comcast patched a bug that under certain conditions leaked customer SSID names and passwords of Xfinity routers.
