Botnet Blitz: TP-Link Routers Under Fire from Six Malware Armies – Secure Your AX21 Now!

Beware, your TP-Link Archer AX21 may be a botnet’s dream! Cyber crooks have found a playground in its security flaw, CVE-2023-1389, and they’re not playing nice. Time to patch up or join the zombie router apocalypse! #BotnetBeware #SecureYourRouter

Hot Take:

It’s like a Black Friday sale for cybercrooks, and TP-Link routers are the doorbusters! CVE-2023-1389 is the secret password into the TP-Link Archer AX21 club, and botnets are lining up like it’s the hottest nightclub in town. Six different malware mobs are DJing this hackathon, dropping beats with command injections that make your router do the worm across the worldwide web. Patch your firmware, folks, or your router might just join the conga line of compromised devices!

Key Points:

  • TP-Link Archer AX21 routers are being targeted by at least six botnet families due to an unpatched command injection vulnerability (CVE-2023-1389).
  • The flaw was patched in March 2023, but evidently, some folks missed the memo and are hosting botnet block parties on their routers.
  • Fortinet has seen a veritable festival of infection attempts, with the daily RSVP list hitting between 40,000 to 50,000.
  • These botnets aren’t just here for the refreshments; they’re launching DDoS attacks, hiding their tracks, and using your router to do their dirty work.
  • If you don’t want your router to be the life of the cybercrime party, TP-Link urges you to update your firmware and practice good cyber hygiene.
Cve id: CVE-2023-1389
Cve state: PUBLISHED
Cve assigner short name: tenable
Cve date updated: 08/11/2023
Cve description: TP-Link Archer AX21 (AX1800) firmware versions before 1.1.4 Build 20230219 contained a command injection vulnerability in the country form of the /cgi-bin/luci;stok=/locale endpoint on the web management interface. Specifically, the country parameter of the write operation was not sanitized before being used in a call to popen(), allowing an unauthenticated attacker to inject commands, which would be run as root, with a simple POST request.

The Party Crashers

Imagine your router as an exclusive nightclub. Now, imagine it with zero bouncers at the door. That's the CVE-2023-1389 vulnerability for you. It's an all-access pass for botnets like Mirai's cousins—three times removed—and other bad actors like Condi, who seems to think your router's resources are part of a buffet. These malware variants are not just visiting; they're moving in, redecorating, and throwing wild DDoS parties without your permission.

The Surge in Gatecrashers

Fortinet's basically the neighborhood watch, and they're reporting a surge in these digital delinquents. We're talking about 40,000 to 50,000 attempts daily to transform routers into robotic minions. It's like a zombie apocalypse but with a lot more IP addresses and less brain-eating. Each botnet brings its own flavor of chaos, from the Golang-based AGoent that plays hide-and-seek with files, to Moobot and Miori, who fancy themselves as brute-force artists.

Don't Host the Afterparty

Despite TP-Link's best efforts to send out firmware updates like party invitations, some routers are apparently still stuck in 2022, and the botnets are loving it. They're exploiting old vulnerabilities and using routers to throw their own cyber soirees. But, just like with any good party, cleanup is a nightmare. Except instead of a messy house, you get a compromised network and possibly a starring role in a botnet's next DDoS attack.

RSVP to Security

TP-Link is like that friend who tells you to drink water between cocktails. They're advising router owners to update their firmware, sling a new, strong password on their admin accounts, and maybe just shut the door to web access if it's not needed. Think of it as sending the "party's over" text before things get out of hand. You don't want your router to be the last one standing when the cyber police show up, do you?

Cybersecurity: The Morning After

So, here's the deal: if you're a TP-Link Archer AX21 owner, it's time to adult-up in the cybersecurity world. Update your firmware, change those passwords, and maybe don't let your router go wandering through the web without a chaperone. It's a wild digital world out there, and you certainly don't want to be nursing a cyber hangover from a botnet bash gone wrong.
