Billions of devices at ‘severe risk’ of attack from flaw

How to fix the 'log4j' security vulnerability

by Kurt Knutsson

High profile hacks are underway as a result of a flaw found in countless servers and internet software powering thousands of familiar products such as Apple iCloud.

The flaw creating a massive security problem is located in a snippet of code called Log4j used by a vast amount of internet applications around the world to help track users’ activity.

Left unfixed, the US Cybersecurity and Infrastructure Security Agency director Jen Easterly says in a statement, “To be clear, this vulnerability poses a severe risk”. The warning goes on to ask that ‘urgent action’ be taken by vendors to upgrade to a patched version 2.15.0 immediately.

Why this attack is big problem getting elevated urgency

The flawed Log4j code is widely used by nearly every company within numerous systems for products and services that you and I likely use several times a day. It is likely to be the root cause of millions of hacks around the world so far.

The vulnerability is creating the perfect security storm and potentially disastrous trouble for these two simple yet powerful factors in the threat.

Two prongs that spell trouble

1) It’s easy for hackers to exploit and 2) is so widespread that it’s likely to take weeks to months to minimize potential impacts.

Here’s how it works

The log4j vulnerability takes data from an internet application and stores it elsewhere. A feature that allows it to execute code now has hackers exploiting it to send malware.

Awareness of the vulnerability started last Thursday when the vulnerability was weaponized by hackers to steal cryptocurrency and hack into some Minecraft servers.

How to fix the log4j vulnerability

The U.S. top security agency is recommending companies and governments take 3 immediate steps:

  1. Identify any external facing devices that have log4j installed
  2. Make sure their security operations centers are actioning every single alert
  3. Install a web application firewall (WAF) with rules that automatically update

For us as consumers, make sure you keep your operating software up to date.
