‼️ BREAKING: The private keys of 8 certificates from Indian certificate authority eMudhra were compromised, Mozilla says. Firefox blocked them within 3 hours. Each key should be a 116-digit number, but one was just 4. Anyone can guess them and forge HTTPS certs for any website.

‼️ Amazon says an attacker tried to exploit PHP2Shell four days before PHP disclosed the two flaws. Its MadPot honeypots logged it on 17 October from an anonymisation network, while the bugs were under embargo. Nobody knows how the attacker got the exploit details.

‼️ BREAKING: eMudhra, the Indian certificate authority whose private key was the number 4, is quitting the TLS business. It blames social media for scrutiny "out of proportion" to a unit worth ~1% of revenue. 8 of its CA keys were numbers below 256, cracked in milliseconds.

❗️ The UK wants up to 14 years in prison for deliberately damaging an undersea cable. It wants to replace an 1885 law that was written for telegraphs. This comes after accusations of Russia actively mapping cables north of the UK to be able to destroy them during wartime. In a security crisis, ministers could also order telecoms firms to hand over data, let officials into cable landing stations and switch off equipment. Refusing could cost 10% of global turnover.

❗️ A Hacker News user apologised for posting the PHP2Shell CVE IDs two days early, saying his contact told him there was no embargo. PHP moved its patch up a day as the IDs spread. Amazon says attackers were already trying the exploit on 17 October, three days before his post.
