Most of these logins are default usernames and passwords from the IoT vendor. If the IoT device allows the Telnet access, the victim's IP, along with the successfully used credential is sent to a collection server. There are a large number of IoT devices which use default settings, making them vulnerable to infection.
Researchers at the SysAdmin, Audit, Network and Security (SANS) institute urged administrators and security researchers to run the latest version of Cowrie on a honeypot to monitor shifts in the type of passwords being scanned for and pattern of attacks on IoT devices. [6] [7] [8]
Poorly secured Internet-accessible IoT devices can also be subverted to attack others. In 2016, a distributed denial of service attack powered by Internet of things devices running the Mirai malware took down a DNS provider and major web sites. [279] The Mirai Botnet had infected roughly 65,000 IoT devices within the first 20 hours. [280]
But because these attacks happen in cyberspace, the battlefield is less tangible, and nation-state attacks blend in with service outages like AT&T’s, which turned out to be a software update ...
IoT forensics takes care of finding evidences for forensics purposes: the evidences are not always related to IoT devices attacks or to their security, but can be used for proving/disproving a traditional forensic crime (i.e. a person detected in a room from IoT devices evidence). In the other side, IoT security takes care of the risks related ...
These attacks can compromise a wide array of devices, including smart plugs, security cameras, and even household appliances. A recent study [12] demonstrated that a substantial portion of consumer IoT devices are prone to replay attacks. Researchers found that 75% of tested devices supporting local connectivity were vulnerable to such attacks.
The attribution of the attack to the Mirai botnet had been previously reported by BackConnect Inc., another security firm. [35] Dyn stated that they were receiving malicious requests from tens of millions of IP addresses. [6] [36] Mirai is designed to brute-force the security on an IoT device, allowing it to be controlled remotely.
Recent attacks are not just by private entities. Some recent hacks of water utilities are linked to geopolitical rivals, and could lead to the disruption of the supply of safe water to homes and ...
