GMB182 has often been used in the past by botnet malware. Of those, all but one-GMB182-were factory default passwords. The top 10 passwords, as tallied by Anubhav, were: The vast majority of the 144 unique pairs, however, were factory-default credentials. While some of the exposed passwords had been changed, even those remained weak enough to be deduced using brute forcing, a technique that repeatedly submits the most commonly used usernames and passwords into telnet-accessible devices in hopes of guessing the right combination.

The list was posted by someone who has previously published a host of valid log-in credentials and botnet source code that has proven useful to security professionals, Ankit Anubhav, a researcher with NewSky Security, told Ars. Some IPs in the list showed more than one username-password pair, either because that device had more than one account or because the device had been infected by malware on subsequent scans. Overall, the list included more than 33,000 records, presumably because it had been updated over time from multiple Internet scans without redundant entries being removed. The ready availability of addresses means a single device could be taken over by multiple groups. Even if a device is currently infected by such a botnet, it's often possible for a rival botnet operator to seize control of it by causing it to restart, since most of the malware can't survive a reboot. The username-password combination mother:fucker, for instance, is used by some IoT botnets once they infect a device. Some of the credentials included in the list suggest that some of the devices have already been conscripted into botnets. Still, that's enough to bring plenty of smaller sites down almost instantly. Based on that figure, the 2,174 currently available devices in the list that came to light Thursday are capable of only a small fraction of that firepower. According to OVH, the France-based Web host, the 1.1-terabit-per-second barrage was delivered by roughly 145,000 devices.

Unlike more traditional botnets that infected Windows computers, the new generation targeted routers, security cameras, and other Internet-connected devices. The botnets that made these once-unthinkable attacks possible carried names such as Mirai and Bashlight. Around the same time, a French Web host reported sustaining onslaughts of 1.1 terabits per second. Security site KrebsOnSecurity, for instance, was taken down for days by attacks that delivered a then-staggering 620 gigabits per second of network traffic. A man and his dog can now grab a readily available list and start owning those IPs." Advertisementįurther Reading Record-breaking DDoS reportedly delivered by >145k hacked camerasLast year, several botnets came to light that drastically increased the potency of DDoS botnets, which use thousands of computers or other Internet-connected devices all over the world to bombard a single target with more junk traffic than it can process. "However, a list such as we're seeing on Pastebin makes a known bad situation much worse as it trivializes the effort involved in other people connecting to them. "There's not much new about devices standing out there with default or weak credentials," Troy Hunt, a security researcher and maintainer of the Have I Been Pwned breach notification service, told Ars. By Friday afternoon, there were more than 13,300 views. That quickly changed Thursday with this Twitter post. Still, for most of its existence, the list remained largely unnoticed, with only some 700 views. It is likely that criminals have been using the list for months as a means to infect large numbers of devices with malware that turns them into powerful denial-of-service platforms. In a testament to the poor state of IoT security, the 8,233 hosts use just 144 unique username-password pairs. Of those active telnet services, 1,774 remain accessible using the leaked credentials, Gevers said. It contains user names and passwords for 8,233 unique IP addresses, 2,174 of which were still running open telnet servers as of Friday morning, said Victor Gevers, chairman of the GDI Foundation, a Netherlands-based nonprofit that works to improve Internet security.
The list of telnet-accessible devices, currently posted at this Pastebin address, was first posted in June, but it has been updated several times since then.
Security researchers have unearthed a sprawling list of login credentials that allows anyone on the Internet to take over home routers and more than 1,700 "Internet of things" devices and make them part of a destructive botnet.
