Log4j Bug: The Worst Cyberthreat in a Decade, Affecting Google, Apple, Amazon, Netflix and More!
What Is log4j & Why Does It Matter?
“Log4Shell” is the name of the bug recently discovered in the Java “log4j” tool. It is being regarded by many as the worst hack ever encountered.
The internet is on fire right now, figuratively speaking. In addition, it has been claimed that in the 12 hours following the bug’s existence being reported, it had already been fully weaponized by cybercriminals. Amit Yoran of Tenable, called it “the single biggest, most critical vulnerability of the last decade”. Log4Shell has also been rated 10/10 by the Apache Software Foundation in its threat score.
Experts are urging companies to patch up immediately — the problem being “That could take hours, days or even months depending on the organization,” said Jon Clay, vice president of threat intelligence here at Trend Micro.
Are Hackers Exploiting It?
Log4Shell grants criminals and spies easy access to internal networks where they can steal data, plant malware and erase information. Because almost every company uses Java, everyone is at risk.
“I’d be hard-pressed to think of a company that’s not at risk,” said Joe Sullivan of Cloudflare. The truth is that millions of servers have it installed. Those proven to be vulnerable include: Google, Amazon, Netflix, Android, Apple, IBM, Tesla, Badu, Twitter, Steam, Alibaba, and Minecraft (where the bug was first encountered).
Anyone with the bug know-how can obtain full access to a computer that uses the same Java software. It is as simple as copying, pasting, and sending some code text in a message. It was users on Minecraft who first illustrated Log4Shell’s capability. Users were found to be taking control of rivals’ computers with the bug by simply pasting a short code message in the chatbox.
60 mutant strains have been detected — causing grave concern for the future. Experts have stated that it could be “months if not years” before the bug is effectively countered.
