The vulnerability, dubbed `Log4Shell,´ was rated 10 on a scale of one to 10 the Apache Software Foundation, which oversees development of the software. He explained: 'The Log4j vulnerability is a significant threat for exploitation due to the widespread inclusion in software frameworks, including the NSA's GHIDRA (a free open source reverse engineering tool)'.Īmit Yoran, CEO of the cybersecurity firm Tenable, called it 'the single biggest, most critical vulnerability of the last decade' - and possibly the biggest in the history of modern computing. The scare prompted senior intelligence experts to react, including Robert Joyce, director of cybersecurity at the National Security Agency in America. Hackers are also understood to be able to use QR codes, whose use was widely popularised throughout the pandemic for NHS Test and Trace purposes, to run malicious code on servers. Amazon, Twitter and Apple's iCloud are understood to be 'vulnerable' to the exploit. Untold millions of servers have it installed, and experts said the fallout would not be known for several days.
Until it is resolved, criminals, spies and programming novices alike are granted easy access to internal networks where they can steal valuable data, plant malware, erase crucial information and much more. 'Log4Shell' was uncovered in a utility that's ubiquitous in cloud servers and enterprise software used across industry and government.
'I would be hard-pressed to think of a company that´s not at risk,' said Joe Sullivan, chief security officer for Cloudflare, whose online infrastructure protects websites from malicious actors.
