Klarna: Yaron Shaer served as interim CISO, February-September 2024

Klarna Group's annual report on Form 20-F traces current Chief Technology Officer Yaron Shaer's path through three roles at the company, one of them a seven-month stretch leading information security.

"He previously served as our interim Chief Information Security Officer from February to September 2024 and as our Co-Chief Technology Officer from January to March 2022, when he assumed his current role," the filing states.

Shaer joined Klarna in June 2014 and has held several engineering leadership positions there before his most recent moves. The filing does not name who held the CISO seat on either side of his interim stint, or why it needed interim coverage while he was already serving as full-time CTO.
