Patch now! The Mirai IoT botnet is exploiting TP-Link routers

Businesses should update their TP-Link routers with the latest firmware to prevent them from being targeted by the Mirai botnet, which is currently using the routers to launch DDoS attacks. The botnet is exploiting a high-severity security vulnerability in the TP-Link Archer AX21 Wi-Fi router that was first disclosed by bug hunters in December 2022. TP-Link issued an initial firmware update that did not properly fix the issue, followed by another update in March 2023 that did resolve the vulnerability. Unfortunately, malicious hackers had already incorporated the flaw into Mirai’s arsenal, leading to the current attacks.

The only recommended action to prevent the exploitation of the vulnerable TP-Link routers is to update them with the latest firmware update, which closes the security hole. The Mirai botnet first gained notoriety in October 2016 when it launched a massive DDoS attack on DNS service company Dyn, making it impossible for many users to reach popular sites such as Amazon, Reddit, Netflix, Twitter, Soundcloud, Spotify, Etsy, and Github. Three men were subsequently sentenced for their part in the running of the Mirai botnet.

The warning about the vulnerability in TP-Link Archer AX21 routers comes from security researchers and the US Government’s Cybersecurity and Infrastructure Security Agency (CISA). The flaw allows malicious hackers to execute malicious code remotely, making it a severe threat to businesses and individuals who use the vulnerable routers. The firmware update resolves the issue, and businesses should act quickly to patch their routers to prevent them from being exploited by Mirai or other botnets.

The Mirai botnet’s use of TP-Link Archer AX21 routers highlights the importance of keeping all devices updated with the latest firmware to prevent them from being used in DDoS attacks or other malicious activities. Businesses should also implement robust cybersecurity measures to protect themselves from these types of threats. The consequences of a successful DDoS attack can be severe, with potential downtime, lost revenue, and damage to a company’s reputation. Therefore, businesses should take proactive steps to secure their networks and devices against these types of attacks.

In summary, businesses should update their TP-Link routers with the latest firmware to prevent them from being targeted by the Mirai botnet. The botnet is exploiting a high-severity security vulnerability that allows it to launch DDoS attacks. The only recommended action to prevent the exploitation of the vulnerable routers is to update them with the latest firmware. Businesses should also implement robust cybersecurity measures to protect themselves from these types of threats. Keeping all devices updated with the latest firmware is essential to prevent them from being used in DDoS attacks or other malicious activities.
