The post revealed that an attempt of a sophisticated attack on their computer systems is witnessed by them.
For treacherous intentions, the hacker, if succeeded, would be able to inflict computer systems via downloading code (virus) onto their systems. Fortunately, this hacking attempt got timely impeded.
Two Firefox 0-day vulnerabilities were referred to in the said blog post which took place back in May and June. For a layman, Firefox 0-day vulnerability is a jargon used for a loophole in the computer software which if goes untreated allows hackers to get the system penetrated.

This was a “sophisticated, highly targeted, thought out attack that used spear-phishing/social engineering tactics and, most importantly, two Firefox 0-day vulnerabilities.
Nevertheless, everything is safe and protected, fortunately, because of the timely action taken by Coinbase. Above everything, contrarily to Binance, this time the hacker failed at getting hold of tons of KYC data.
