BOSTON: A software vulnerability exploited in the online game Minecraft is rapidly emerging as a major threat to internet-connected devices around the world.
The internets on fire right now,” said Adam Meyers, senior vice president of intelligence at the cybersecurity firm Crowdstrike. “People are scrambling to patch and there are script kiddies and all kinds of people scrambling to exploit it.” He said Friday morning that in the 12 hours since the bug’s existence was disclosed that it had been “fully weaponized, meaning that malefactors have developed and distributed tools to exploit.
The flaw may be the worst computer vulnerability discovered in years. It opens a loophole in software code that is ubiquitous in cloud servers and enterprise software used across industry and government. It could allow criminals or spies to loot valuable data, plant malware or erase crucial information, and much more.
Id be hard-pressed to think of a company thats not at risk, said Joe Sullivan, chief security officer for Cloudflare, whose online infrastructure protects websites from malicious actors. Untold millions of servers have it installed, and experts said the fallout would not be known for several days.
Amit 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 vulnerability, dubbed Log4Shell, was rated 10 on a scale of one to 10 the Apache Software Foundation, which oversees development of the software. Anyone with the exploit can obtain full access to an unpatched computer that uses the software,
New Zealand’s computer emergency response team was among the first to report that the flawwas being actively exploited in the wild” just hours after it was publicly reported Thursday and a patch released.
The vulnerability, located in open-source Apache software used to run websites and other web services, was discovered Nov. 24 by the Chinese tech giant Alibaba, the foundation said.
Finding and patching the software could be a complicated task. While most organizations and cloud providers should be able to update their web servers easily, the same Apache software is also often embedded in third-party programs, which often can only be updated by their owners.
Yoran, of Tenable, said organizations need to presume theyve been compromised and act quickly.
The flaw’s exploitation was apparently first discovered in Minecraft, an online game hugely popular with kids and owned by Microsoft.
Meyers and security expert Marcus Hutchins said Minecraft users had already been using it to execute programs on the computers of other users by pasting a short message in a chat box.
Microsoft said it had issued a software update for Minecraft users. Customers who apply the fix are protected, it said.
Researchers reported finding evidence the vulnerability could be exploited in servers run by companies such as Apple, Amazon, Twitter and Cloudflare.
Cloudflare’s Sullivan said there we no indication his company’s servers had been compromised. Apple, Amazon and Twitter did not immediately respond to requests for comment.
