Serious bug puts Apple iCloud, Twitter, Minecraft at hacking threat


Several popular services, including Apple iCloud, Amazon, Twitter, Cloudflare and Minecraft, are vulnerable to a ‘ubiquitous’ zero-day exploit, cybersecurity researchers have warned, leaving IT security teams at several companies scrambling to patch the vulnerability called ‘Log4Shell’.

The ‘zero-day’ exploit (which is a cyber attack targeting a software vulnerability which is unknown to the software/antivirus companies) is found in the widely-used Java logging system called ‘log4j2’.

If exploited, the vulnerability allows remote code execution (RCE) on vulnerable servers, giving hackers the ability to import malware that would completely compromise millions of machines.

“Many, many services are vulnerable to this exploit. Cloud services like Steam, Apple iCloud, and apps like Minecraft have already been found to be vulnerable,” said researchers from application security company LunaSec.
