#SKTelecom #cyberattack : Free #SIM replacements for 25 million customers

#SouthKorean mobile provider SK Telecom has announced free SIM card replacements to its 25 million mobile customers following a recent #USIM data breach, but only 6 million cards are available through May.

SK Telecom is the country's largest #mobile network operator, serving roughly half of the domestic mobile phone market

“The Portuguese prime minister, Luís Montenegro, said that the issue originated in Spain. Portugal’s REN said a “rare atmospheric phenomenon” had caused a severe imbalance in temperatures that led to the widespread shutdowns.“

So, it probably wasn’t a cyberattack that caused the outages in Spain and Portugal.

The cause was likely weather conditions caused by climate change.

Wanna bet most people I’ll talk to tomorrow will feel relieved?

Now take a guess what is more dangerous: cyberattacks, or climate chaos?

As someone once said: “fear is the mind-killer”. 🤷🏻‍♂️

Oh really it was Ukraine that took down X on March 10? Not so fast.

Independent security researchers found evidence that some X origin servers were not properly secured behind DDoS protection, and researchers noted they did not even see Ukraine in the breakdown of the top 20 IP address origins involved in the attacks. wired.com/story/x-ddos-attack- #X #Musk #DDoS #cyberattack #cybersecurity #security #Ukraine #BotNet #Internet
