Chrome Zero-Day from North Korea

North Korean hackers have been exploiting a zero-day in Chrome.

The flaw, tracked as CVE-2022-0609, was exploited by two separate North Korean hacking groups. Both groups deployed the same exploit kit on websites that either belonged to legitimate organizations and were hacked or were set up for the express purpose of serving attack code on unsuspecting visitors. One group was dubbed Operation Dream Job, and it targeted more than 250 people working for 10 different companies. The other group, known as AppleJeus, targeted 85 users.

Details:

The attackers made use of an exploit kit that contained multiple stages and components in order to exploit targeted users. The attackers placed links to the exploit kit within hidden iframes, which they embedded on both websites they owned as well as some websites they compromised…

There aren’t many weak keys out there, but there are some:

So far, Böck has identified only a handful of keys in the wild that are vulnerable to the factorization attack. Some of the keys are from printers from two manufacturers, Canon and Fujifilm (originally branded as Fuji Xerox). Printer users can use the keys to generate a Certificate Signing Request. The creation date for the all the weak keys was 2020 or later. The weak Canon keys are tracked as CVE-2022-26351…
