The decline in Lumen's stock price can be attributed to the ongoing cyberattack affecting major telecommunications companies, including Lumen, as reported in recent news.

The uncertainty surrounding the resolution of this cyberattack has likely contributed to the negative sentiment and downward pressure on Lumen's stock.
