BrickerBot was malware that attempted to permanently destroy ("brick") insecure Internet of Things devices. BrickerBot logged into poorly-secured devices and ran harmful commands to disable them. It was first discovered by Radware after it attacked their honeypot in April 2017. On December 10, 2017, BrickerBot was retired.
The most infected devices were in Argentina, followed by North America and Europe, and Asia (including India).[1]
The BrickerBot family of malware was first discovered by Radware on April 20, 2017, when BrickerBot attacked their honeypot 1,895 times over four days. BrickerBot's method of attack was to brute-force the telnet password, then run commands using BusyBox to corrupt MMC and MTD storage, delete all files, and disconnect the device from the Internet. Less than an hour after the initial attack, bots began sending a slightly different set of malicious commands, indicating a new version, BrickerBot.2. BrickerBot.2 used the Tor network to hide its location, did not rely on the presence of busybox on the target, and was able to corrupt more types of storage devices.[2]
BrickerBot.3 was detected on May 20, 2017, one month after the initial discovery of BrickerBot.1. On the same day, one device was identified as a BrickerBot.4 bot. No other instances of BrickerBot.4 were seen since.[3]
According to Janit0r, the author of BrickerBot, it destroyed more than ten million devices before Janit0r announced the retirement of BrickerBot on December 10, 2017.[4] In an interview with Bleeping Computer, Janit0r stated that BrickerBot was intended to prevent devices from being infected by Mirai.[5][6] US-CERT released an alert regarding BrickerBot on April 12, 2017.[7]

In computing, a denial-of-service attack (DoS attack doss) is a cyberattack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to a network. Denial of service is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fulfilled. The range of attacks varies widely, spanning from inundating a server with millions of requests to slow its performance or with a substantial amount of invalid data, to submitting requests with an illegitimate IP address, and launching "low and slow" attacks aimed at keeping connections open. In a distributed denial-of-service attack (DDoS attack DEE-doss), the incoming traffic flooding the victim originates from many different sources. More sophisticated strategies are required to mitigate this type of attack; simply attempting to block a single source is insufficient. A DDoS attack is analogous to a group of people crowding the entry door of a shop, making it hard for legitimate customers to enter, thus disrupting trade and losing the business money. Criminal perpetrators of DDoS attacks often target sites or services hosted on high-profile web servers such as banks or credit card payment gateways. Revenge and blackmail, as well as hacktivism, can motivate these attacks.
Infineon Technologies AG is a German company which designs and manufactures semiconductor devices. It provides parts for automotive, power and security systems. In 2023, Infineon was Germany's largest chip manufacturer, and had roughly 57,000 employees in 2025. Infineon was spun-off from Siemens, a German engineering conglomerate in April 1999; one year later, it underwent the largest initial public offering (IPO) for a tech company to date despite Siemens retaining a 74 percent stake in the business. By 2026, Infineon's operations had been restructured into three distinct business areas: Automotive (ATV), Power Systems (PS) and Edge Systems (ES). According to Handelsblatt, Infineon is Germany’s largest semiconductor manufacturer and ranks among the top ten semiconductor manufacturers worldwide.
Petya is a family of encrypting malware that was first discovered in 2016. The malware targets Microsoft Windows–based systems, infecting the master boot record to execute a payload that encrypts a HDD or SSD file system table and performs a fake CHKDSK after a restart. This prevents Windows from booting, as the master boot record is overwritten; subsequently, Petya demands that users make a Bitcoin payment to regain access. Variants of Petya were first seen in March 2016, which propagated via infected e-mail attachments. In June 2017, a new variant of Petya was used for a global cyberattack, primarily targeting Ukraine. The new variant propagates via the EternalBlue exploit, which is generally believed to have been developed by the U.S. National Security Agency (NSA), and was used earlier in the year by the WannaCry ransomware. Kaspersky Lab referred to this new version as NotPetya to distinguish it from the 2016 variants, due to these differences in operation. Although it appeared to be ransomware, due to its lack of a decryption method, it was equivalent to a wiper. The NotPetya attacks have been blamed on the Russian government, specifically the Sandworm hacking group within the GRU Russian military intelligence organization, by security researchers, Google, and several governments.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
