Think about a complicated cyberattack cripples your group’s most important productiveness and collaboration instrument — the platform you depend on for each day operations. Within the blink of a watch, hackers encrypt your emails, information, and essential enterprise information saved in Microsoft 365, holding it hostage utilizing ransomware. Productiveness grinds to a halt and your IT staff races to evaluate the harm because the clock ticks down on a ransom demand that threatens to destroy your information without end. How did this occur, and extra importantly, how are you going to stop it from taking place?
Microsoft 365 (M365) is the lifeblood of numerous organizations worldwide, providing a seamless, cloud-based platform for communication, collaboration and information administration. Over 400 million customers depend on Microsoft 365 for the whole lot 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 primary goal for cybercriminals.
On this article, we study the vulnerabilities in Microsoft 365 and focus on how proactive information safety methods, which leverage devoted third-party backup options like Backupify, enable companies to strengthen their defenses in opposition to the rising menace of ransomware and different cyber dangers.
Why is M365 a lovely goal?
Understanding why Microsoft 365 is so engaging to attackers is essential to fortifying your defenses. This 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 at this time. Its widespread utilization additionally implies that a profitable assault can doubtlessly impression hundreds of thousands of organizations, making it a profitable goal for malicious actors. Cybercriminals can use varied strategies, similar to phishing, brute power assaults and credential stuffing, to take advantage of weak factors and acquire unauthorized entry.
Built-in providers
Microsoft 365 integrates varied providers, similar to Outlook, SharePoint, Groups and OneDrive, creating an entire ecosystem for customers. Whereas this enhances productiveness and collaboration, it additionally broadens the assault floor for cybercriminals with a number of entry factors. If menace actors compromise one service, similar to a consumer’s electronic mail account, they may acquire entry to your complete suite.
Consumer-centered assaults
Cybercriminals typically concentrate on customers, who’re regularly 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 consumer’s account is compromised — particularly an administrator account — the attacker can acquire elevated permissions, doubtlessly permitting them to entry the group’s total information repository, resulting in information theft, unauthorized information manipulation and even full-scale ransomware assaults. In 2023, over 68 million messages had been linked to Microsoft merchandise and branding, positioning it as essentially the most exploited model by menace actors that 12 months2.
Worthwhile information within the cloud
On common, a terabyte of cloud storage accommodates over 6,000 information with delicate info3. Microsoft 365 shops giant volumes of delicate enterprise information, together with monetary data, mental property and private info, making it a great goal for ransomware assaults.
Widespread vulnerabilities and exposures (CVEs)
Like all software program, Microsoft 365 is vulnerable 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 programs earlier than organizations have an opportunity to guard themselves.
Microsoft 365’s giant and sophisticated setting makes it extra vulnerable to those sorts of threats since managing and patching vulnerabilities throughout such an intensive platform will be difficult for organizations. A profitable zero-day exploit can present cybercriminals with unauthorized entry, enabling them to launch additional assaults or exfiltrate information.
Microsoft has had over 1,200 software program vulnerabilities over the previous 4 years4. Elevation of privilege has persistently been the highest vulnerability class annually.
Crucial errors weakening Microsoft 365 safety
Though Microsoft 365 is a strong platform, sure end-user shortcomings could make it susceptible 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 via brute-force assaults and credential stuffing. As soon as a weak password is cracked, attackers can acquire entry to delicate info, impersonate customers and even escalate their privileges inside the group.
- Lack of multifactor authentication (MFA): Along with a consumer’s password, MFA requires a one-time verification code or biometric information 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 consumer accounts susceptible to compromise, particularly in instances the place passwords are stolen or guessed. As per the Nice SaaS Knowledge Publicity report, 55% of tremendous admin accounts and 44% of privileged accounts didn’t have MFA.
- Misconfigured safety settings and consumer permissions: Misconfigured safety settings or extreme consumer permissions should not new to Microsoft 365 environments. These can open the doorways to safety dangers. For instance, customers might have extra privileges than needed or delicate paperwork could also be shared publicly by mistake.
- Insufficient electronic mail filtering and consumer safety: Phishing stays one of the efficient techniques for cybercriminals, and insufficient electronic mail filtering can go away organizations susceptible to those assaults. With out superior electronic mail safety instruments that may detect and block phishing makes an attempt, malicious hyperlinks and attachments, customers are vulnerable to inadvertently putting in malware or offering credentials to attackers.
- Improper consumer lifecycle administration: Cybercriminals can exploit accounts belonging to ghost customers — energetic accounts of former workers or unused accounts that have not been deactivated — to achieve unauthorized entry to the group’s community and information. The Nice SaaS Knowledge Publicity report revealed that just about 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 information accurately: Many organizations wrongly assume that as a result of their information is saved within the cloud, it’s routinely 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 software uptime and infrastructure safety, information safety is the shopper’s accountability. With no dependable backup technique, unintentional deletion or cyberattacks can lead to everlasting information loss or corruption.

Id safety options monitor for indicators of compromised identities and assist mitigate dangers earlier than they are often exploited.
Vulnerability assessments and penetration testing
It’s essential to usually assess your Microsoft 365 setting to determine potential weak factors that menace actors might exploit. Vulnerability assessments scan your system for recognized points, similar to unpatched software program or misconfigurations, and supply suggestions for remediation. Penetration testing simulates real-world assaults to see how your defenses maintain up. This helps uncover hidden vulnerabilities, permitting you to deal with them earlier than they are often exploited.
Consumer consciousness coaching
Customers are sometimes the weakest hyperlink within the cybersecurity chain, particularly relating to phishing and social engineering assaults.
