I wouldn't call CDU left wing. They appear to have spared the "most right" party in parliament (AfD), tho.
In addition to hacking the systems of political parties, they also hacked many left-wing musicians, artists, TV hosts of late night shows, etc.
I've clarified my original post with a footnote.
But here in Germany, CDU was always considered "right".
For example, CDU/CSU politicians didn't want gay people to call what they have a "marriage". Merkel said so back in 2017, and eventually voted against the law together with more than 2/3rds of her party; the law passed anyway with the votes of the CDU's coalition partner SPD and the opposition parties. So there are some commonalities with the US right wing politicians and their policies, after all.
