If an IoT device responds to the probe, the attack then enters into a brute-force login phase. During this phase, the attacker tries to establish a telnet connection using predetermined username and password pairs from a list of credentials. Most of these logins are default usernames and passwords from the IoT vendor.
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]
These attacks are wide-ranging, global and do not seem to discriminate among governments and companies. Operation Shady RAT; World of Hell; Red October, discovered in 2012, was reportedly operating worldwide for up to five years prior to discovery, transmitting information ranging from diplomatic secrets to personal information, including from mobile devices.
WASHINGTON (Reuters) - - An unidentified hacking group launched a massive cyberattack on a telecommunications company in the U.S. heartland late last year that disabled hundreds of thousands of ...
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]
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.
It was said that the FBI, the Secret Service, and other U.S. intelligence agencies categorized the attacks "among the most sophisticated attacks ever launched against U.S. government systems."
