Kaspersky reported one of the iOS vulnerabilities found in Operation Triangulation. However, in a bizarre update, Apple reportedly refused to pay the security bounty.
Kaspersky uncovered iOS vulnerabilities in 'Operation Triangulation', reported to Apple, but was refused bounty payment
Apple's Security Bounty Program offers rewards up to $1 million for discovering vulnerabilities to prevent them from being sold on the dark web
Apple's refusal to pay Kaspersky could be due to restrictions on financial transactions with companies in sanctioned countries like Russia.
I worked for an Australian company, that was bought by an American company. Instantly we were required to do business as per American law, such as embargo's. We lost many customers (businesses) that honestly had nothing to do with the actual reason for the embargos. For example Iran has an American embargo because of nuclear refinement, but we just wanted to sell "knives and forks" to them. Nope - they might use those forks in their refinement centrifuges... This is what happens (but also why embargos work).
Kaspersky is Russian owned, so the hacks were discovered by Russian [whitehat] hackers. I'll bet that Apple had no ability to do "business" with the company, even if it wanted to, since Russia is currently under embargo due to the Ukraine conflict.
Now if Kaspersky spent time undermining it's own failure of a government, and putting an end to its dictatorship, things would probably work out better for everyone in Russia.
Is that the case though. You can buy a copy of Kaspersky anti virus right now if you live in the US. They have a US office. You can legally send them money.
