MFA Bug Opens Door For Hackers To Attack Microsoft 365

New and heightened digital threats develop every day, and having standard security software may not be enough to protect your personal data and business from exploitation from malware attacks. Businesses across industries are vulnerable to new attacks, as many security software lags behind. Hackers find ways to work around the most common security platforms to find new ways into systems to gain access to all sorts of information, and the only way to ensure that you are as protected as possible is to work with an IT expert who knows how to take the preventative measures to keep up with the latest malware developments.

One of the latest bugs causing a lot of damage to businesses is a vulnerability to the Microsoft-based cloud office platform, Microsoft 365. This platform allows businesses to push their productivity almost entirely online, giving employees access to their data from literally anywhere in the world while still collaborating in real-time. The use of cloud platforms allowed businesses to stay productive during the 2020 shutdown. The use has grown exponentially in popularity as everything from law firms, doctors’ offices, and schools have shifted as much business as possible over to the virtual platforms.

Hackers recently exploited a bug present in the multi-factor authentication system for access into the Microsoft 365 platform, which meant that there was a somewhat easily accessible back door into the otherwise secure cloud system. There is a lot of damage done when a hacker can get access to your business or personal data. Information can be stolen or deleted, which could lead to costly repairs as you spend time re-collecting data or ensuring that your employees and clients are protected from additional attacks on their finances and identity based on the type of information accessed by the hackers.

System flaws happen, and typically patches are issued to fix bugs that may allow hackers into programs — especially in the case of well-funded, popular programs like those owned by Microsoft. However, that doesn’t mean that there isn’t a chance of an attack before that patch being issued. Also, if your employees aren’t receiving guidance on keeping up with regular updates and maintenance on their work computers, they could be putting everyone at risk as those updates are how patches are installed. A single point of access through an outdated computer can allow hackers to access all sorts of data.

In the case of the latest vulnerability that impacted Microsoft 365, the issue was present in the WS-Trust, an OASIS standard that delivers security extensions and is used to renew and validate security tokens, thus ensuring identity. A bug in this system could be disastrous, allowing for the easy manipulation of security tokens and identity, allowing hackers in. The attacker could easily access mail, files, data, contacts, and more — depending on the amount of information stored on the cloud.

Working with a strong IT support team is the best way to ensure that you are protected from the latest developments in malware. Keep your computers up to date and your employees knowledgeable on the best ways to stay protected by having a strong IT support team to rely on.
