Internet users, Alert! Serious bug makes Apple iCloud, Twitter, Minecraft vulnerable to hacking

The vulnerability is extremely severe because it may be abused to run any code and requires very little skill on the part of the attacker to exploit.

A new zero-day vulnerability has been found in the popular Java logging framework Log4J, affecting various online services such as Minecraft, Apple's iCloud, Steam and other software and products that use Java in their code. According to cybersecurity analysts, the weakness puts these services vulnerable to hacking, leaving IT security teams at multiple firms hurrying to repair the 'Log4Shell' bug.

The vulnerability, identified as CVE-2021-44228, is extremely severe because it may be abused to run any code and requires very little skill on the part of the attacker to exploit.

Log4j is used by many services and applications. It is an Apache Software Foundation logging package, and the vulnerability affects all versions between 2.0-beta-9 and 2.14.1. While Apache has patched the vulnerability in the most recent version 2.15.0 upgrade, software developers must still install it to safeguard their clients.

The attack has been called "Log4Shell." It is an RCE vulnerability that allows for a complete system takeover. Since many services use Java in their programming and Log4j for logging, they are exposed to this vulnerability.


"Anyone who uses Apache Struts is likely exposed. Similar vulnerabilities have already been exploited in breaches such as the 2017 Equifax data leak "LunaSec, a cybersecurity firm."

A minor switch in the name of an iPhone can trigger the vulnerability. There is considerable evidence that hackers have begun to bulk scan the internet for applications that have yet to be patched for this vulnerability. Those that use Log4j in their software should immediately switch to the newest 2.15 version.

 Many Open Source projects, such as the Minecraft server Paper, have already begun to modify their use of 'log4j2'. The Apache Software Foundation has also released an emergency security upgrade to address the 'log4j' zero-day vulnerability.
