Couldn't find international news coverage of this, so I'll do my best to translate it:
CHP spokesman Deniz Yucel has made a statement about his SIM card getting duplicated and WhatsApp account being hijacked by malicious actors:
"While the methods used by malicious actors are not fully clear, my phone number was taken over in 19 August 2024 around 14:40, via malicious actors pretending to be me to request a new SIM card for my 25 year old number. The SIM card on my phone has been automatically deactivated; the malicious actors first changed my Whatsapp profile picture to President Erdogan, then sending the people I've added or to the visible groups pictures of Alpay Ozalan captions similar to 'would you like Alpay Ozalan to hit you too?'(*), Soon after discovery, we've sent a warning message on social media channels about this incident and contacted to people I've added through WhatsApp, and soon after got the account terminated. We've been in official talks to fully resolve this situation.
Note that this issue isn't caused by any security vulnerability caused by me or the party. This attack was done because of my position within the party. If malicious actors can do this to someone within my position, we can assume no one's communications and personal data is truly safe; but I am leaving what to think of this up to the public. I will be suing my operator turkcell for all damages, and will report this incident to the prosecution's office to pursue anyone involved in this attack.
Don't doubt that we will follow this all the way through and ensure similar incidents won't happen against any of 85 million Turkish citizens."
