Over 400 million customers depend on Microsoft 365 for every little thing from doc creation and administration to video conferencing1. Whereas M365 has empowered companies to bear digital transformation and stay aggressive with its help for distributed, hybrid and distant working environments, its ubiquity and integration have made it a main goal for cybercriminals.
On this article, we look at the vulnerabilities in Microsoft 365 and focus on how proactive knowledge safety methods, which leverage devoted third-party backup options like Backupify, enable companies to strengthen their defenses in opposition to the rising risk of ransomware and different cyber dangers.
Why is M365 a pretty goal?
Understanding why Microsoft 365 is so enticing to attackers is essential to fortifying your defenses. Here is what makes Microsoft 365 a focus for cybercriminals:
Mass adoption
Microsoft 365 is without doubt one of the most generally used cloud-based productiveness platforms in the present day. Its widespread utilization additionally implies that a profitable assault can doubtlessly impression tens of millions of organizations, making it a profitable goal for malicious actors. Cybercriminals can use numerous strategies, equivalent to phishing, brute pressure assaults and credential stuffing, to use weak factors and acquire unauthorized entry.
Built-in providers
Microsoft 365 integrates numerous providers, equivalent to Outlook, SharePoint, Groups and OneDrive, creating a whole ecosystem for customers. Whereas this enhances productiveness and collaboration, it additionally broadens the assault floor for cybercriminals with a number of entry factors. If risk actors compromise one service, equivalent to a person’s e-mail account, they might acquire entry to the whole suite.
Consumer-centered assaults
Cybercriminals usually concentrate on customers, who’re incessantly the weakest hyperlink in any cybersecurity technique. Phishing assaults are designed to deceive customers into revealing their login credentials or putting in malicious software program. As soon as a single person’s account is compromised — particularly an administrator account — the attacker can acquire elevated permissions, doubtlessly permitting them to entry the group’s whole knowledge repository, resulting in knowledge theft, unauthorized knowledge manipulation and even full-scale ransomware assaults. In 2023, over 68 million messages have been linked to Microsoft merchandise and branding, positioning it as essentially the most exploited model by risk actors that 12 months2.
Priceless knowledge within the cloud
On common, a terabyte of cloud storage accommodates over 6,000 recordsdata with delicate data3. Microsoft 365 shops giant volumes of delicate enterprise knowledge, together with monetary data, mental property and private data, making it a really perfect goal for ransomware assaults.
Frequent vulnerabilities and exposures (CVEs)
Like every software program, Microsoft 365 is prone to CVEs, together with zero-day exploits, the place attackers can exploit unknown or unpatched safety gaps. Cybercriminals actively search for such weaknesses to infiltrate methods earlier than organizations have an opportunity to guard themselves.
Microsoft 365’s giant and sophisticated setting makes it extra prone to those sorts of threats since managing and patching vulnerabilities throughout such an intensive platform may be difficult for organizations. A profitable zero-day exploit can present cybercriminals with unauthorized entry, enabling them to launch additional assaults or exfiltrate knowledge.
Microsoft has had over 1,200 software program vulnerabilities over the previous 4 years4. Elevation of privilege has persistently been the highest vulnerability class every year.
Crucial errors weakening Microsoft 365 safety
Though Microsoft 365 is a strong platform, sure end-user shortcomings could make it weak to safety dangers.
- Weak or reused passwords: Many customers depend on weak or reused passwords throughout a number of accounts, making it simpler for attackers to compromise accounts by way of brute-force assaults and credential stuffing. As soon as a weak password is cracked, attackers can acquire entry to delicate data, impersonate customers and even escalate their privileges inside the group.
- Lack of multifactor authentication (MFA): Along with a person’s password, MFA requires a one-time verification code or biometric knowledge for authentication. Whereas MFA gives an efficient protection in opposition to unauthorized entry, many organizations don’t implement MFA for his or her Microsoft 365 accounts. This leaves person accounts weak to compromise, particularly in circumstances the place passwords are stolen or guessed. As per the Nice SaaS Information Publicity report, 55% of tremendous admin accounts and 44% of privileged accounts didn’t have MFA.

With out superior e-mail safety instruments that may detect and block phishing makes an attempt, malicious hyperlinks and attachments, customers are susceptible to inadvertently putting in malware or offering credentials to attackers.
- Improper person lifecycle administration: Cybercriminals can exploit accounts belonging to ghost customers — energetic accounts of former staff or unused accounts that have not been deactivated — to realize unauthorized entry to the group’s community and knowledge. The Nice SaaS Information Publicity report revealed that almost 6 out of 10 stale visitor customers (56%) stay energetic after 90 days, and one-third (33%) are nonetheless enabled even after 180 days, posing vital safety dangers to organizations.
- Failure to again up cloud knowledge appropriately: Many organizations wrongly assume that as a result of their knowledge is saved within the cloud, it’s robotically shielded from loss or corruption. Nevertheless, it is necessary to notice that Microsoft operates on a shared accountability mannequin. As per the mannequin, whereas the cloud supplier ensures utility uptime and infrastructure safety, knowledge safety is the client’s accountability. With no dependable backup technique, unintentional deletion or cyberattacks can lead to everlasting knowledge loss or corruption.
