Hello! If you're with LG Uplus or know someone in South Korea, there is some bad news. LG Uplus, the country's third-largest mobile provider, just confirmed that they had a cyberattack; and they join KT and SK Telecom as companies that were hacked this year.
Have you ever wondered why these major telecommunications companies keep getting hacked? Let's break it down and see what it might mean for you.
• Login information for 42,000+ accounts
• Personal information for at least 167 employees
LG Uplus had conducted a security check as recently as August and did not observe anything suspicious. Once they dug deeper, they confirmed the breach. LG Uplus reported the event to the Ministry of Science and ICT, promising full cooperation with the investigation.
• Phishing emails that appear legitimate
• Try to perpetuate identity theft through the use of leaked account logins
• Try different social engineering attacks while impersonating LG Uplus support
So yes, it's not just numbers on a server — your personal information may be targeted if you're a customer.
• Completely cooperating with the government on an investigation of the hack
• Tripling their cybersecurity budget to KRW100 billion per year
• Learning from a hack in 2023 that impacted nearly 290,000 subscribers and cost the company related compensation
These steps show the company is serious about preventing future hacks — although it also shows how big telecom companies can be vulnerable.
1. Immediately change your account password.
2. Watch your email and any other accounts for unauthorized activity.
3. Be alert to any unsolicited phone calls, text messages, or emails that appear to be from LG Uplus.
4. Use two-factor authentication whenever possible, as this will add an extra layer of security.
And even if the company fixes their systems, your own watchfulness goes a long way.
