Generally speaking, we can split all cyber attacks into two large groups:<\/p>\n\n\n\n
- \n
- Targeted<\/li>\n\n\n\n
- Opportunistic<\/li>\n<\/ul>\n\n\n\n

<\/figure>\n\n\n\n<\/p>\n\n\n\n
Targeted or focused attacks <\/strong>are usually prepared in advance, so you might notice something suspicious before it\u2019s too late. As the name suggests, these attacks are always focused on a specific target<\/em>. Malicious insiders behind a targeted attack spend time gathering information on their victim, planning their actions, and preparing for the actual attack.<\/p>\n\n\n\n
For example, say a departing employee creates a backdoor account no one knows about before they leave<\/em> the organization. They plan on using this account later to regain access to corporate resources and use them to their advantage. This is a classic example of a targeted attack coming from a malicious insider.<\/p>\n\n\n\n
In turn, opportunistic or <\/strong>untargeted attacks<\/strong><\/a> may have no warning signs, as they are often executed spontaneously. Having no specific target, opportunistic attackers simply leverage the situation<\/em> and take what they can get.<\/p>\n\n\n\n
Suppose a recently terminated employee discovers they still have access to their former employer\u2019s corporate network. After this discovery<\/em>, they abuse their remaining access right to tamper with the organization\u2019s data and services. This is a typical example of an opportunistic attack.<\/p>\n\n\n\n
When an opportunistic attack originates from the outside, it\u2019s commonly executed via malware or phishing. But with 98% of organizations<\/a> feeling vulnerable to insider threats, it\u2019s opportunistic insiders you should be aware of.<\/p>\n\n\n\n
Both malicious and opportunistic insiders can have the same motivation<\/a>:<\/p>\n\n\n\n

<\/figure>\n\n\n\n<\/p>\n\n\n\n
Any situation enabling a user to obtain valuable data or get control over critical services without exposing their identity can be seen as an opportunity for an untargeted attack. And the scale of the damage that opportunistic attackers can cause to an organization is mostly limited by the opportunities they are presented with.<\/p>\n\n\n\n

6 key factors behind opportunistic attacks<\/h2>\n\n\n\n
Beware of access misconfigurations and lack of visibility.<\/em><\/p>\n\n\n\n
Let\u2019s take a look at some of the most common factors that can turn a regular user into a malicious insider.<\/p>\n\n\n\n

<\/figure>\n\n\n\n<\/p>\n\n\n\n
1. Excessive access rights<\/strong> \u2014 Misconfigured access permissions<\/a> can make critical assets available to employees who are not supposed to work with them. Some employees may see this as an opportunity to tamper with these assets, either accidentally or intentionally.<\/p>\n\n\n\n
2. Shared sensitive data<\/strong> \u2014 Coworkers tend to share all sorts of sensitive data with each other, from in-team discussions to account passwords. Some people, however, may use this knowledge to gain valuable insights on your trade secrets or execute an attack under someone else\u2019s account.<\/p>\n\n\n\n
3. Shared accounts<\/strong> \u2014 When different people use a single shared account<\/a>, it\u2019s usually difficult to distinguish who did what. Some people might see this lack of transparency as an opportunity to attack.<\/p>\n\n\n\n
4. Unrevoked access rights<\/strong> \u2014 If a promoted, downgraded, or terminated employee doesn\u2019t have their previous access permissions revoked, they can use them to their own advantage.<\/p>\n\n\n\n
5. Unchanged passwords<\/strong> \u2014 In cases where revoking individual access is challenging, like with shared accounts, unchanged passwords allow former employees to maintain access to important services and data even after they leave your company.<\/p>\n\n\n\n
6. Lack of auditing activities<\/strong> \u2014 Not having proper user activity monitoring and auditing routines in place creates an environment conducive to opportunistic attacks. When people know they will be caught, they are unlikely to take an opportunity even when presented with one.<\/p>\n\n\n\n
Now that we\u2019ve explored the basics of opportunistic attacks, let\u2019s talk about ways you can protect your organization from such a threat.<\/p>\n\n\n\n

How to deter an opportunistic attacker?<\/h2>\n\n\n\n
Prevent incidents instead of handling their consequences.<\/em><\/p>\n\n\n\n
The best way to deter opportunistic attackers is not to give them a chance to harm your organization in the first place.<\/p>\n\n\n\n
You need to understand what sensitive information you have and who in your company has access to it. Consider running a thorough risk assessment<\/a> so you can determine exactly what valuable assets need to be protected and from what risks. Once you know the most sensitive spots in your system, you can take proper precautions to ensure their protection.<\/p>\n\n\n\n
Below, we specify four best practices that can help you mitigate the risk of opportunistic attacks.<\/p>\n\n\n\n
![\"best](\"https:\/\/www.syteca.com\/wp-content\/uploads\/2023\/04\/figure-4-7.jpg\")
<\/figure>\n\n\n\n<\/p>\n\n\n\n
1. Limit insider access to critical data.<\/strong> To secure your valuable assets from opportunistic insiders, try implementing these practices:<\/p>\n\n\n\n
- \n
- Follow the principle of least privilege<\/a> so your employees and subcontractors have the exact access permissions they need to do their job.<\/li>\n\n\n\n
- Establish a clear access management policy so that every time someone in your organization changes their position or departs, their access permissions are reviewed or revoked.<\/li>\n\n\n\n
- Educate your employees<\/a> on data protection basics so they know exactly what information they can share with whom and to what extent.<\/li>\n<\/ul>\n\n\n\n

2. Manage passwords securely.<\/strong> Weak and outdated passwords create additional risks for you and opportunities for malicious actors. To minimize cybersecurity risks related to credential compromise, consider the following recommendations:<\/p>\n\n\n\n
- \n
- Set clear rules for password use, focusing on minimal password requirements, password rotation, and credential sharing routines. And make sure to educate your employees on these rules.<\/li>\n\n\n\n
- Deploy a password management tool that will help you secure and automate password creation, rotation, and termination.<\/li>\n\n\n\n
- Look at relevant compliance regulations and cybersecurity standards for additional password management guidance.<\/li>\n<\/ul>\n\n\n\n

3. Secure shared accounts.<\/strong> While it may create additional cybersecurity risks, having accounts accessed and managed by multiple users is a necessity for many organizations. If replacing shared accounts with similar individual ones is not an option for you, here\u2019s what you can do to improve account security:<\/p>\n\n\n\n
- \n
- Change passwords to shared accounts every time someone with access changes their position or leaves your organization.<\/li>\n\n\n\n
- Add one more layer of user authentication so you can distinguish the actions of different users under the same account.<\/li>\n<\/ul>\n\n\n\n

4. Monitor and audit user activity. <\/strong>Deploying user activity monitoring software<\/a> and performing regular internal audits can not only help you detect early signs of an insider attack but provide you with a few more benefits:<\/p>\n\n\n\n
- \n
- Detect misconfigured access permissions<\/li>\n\n\n\n
- Find inactive and suspicious accounts that need to be deactivated or deleted<\/li>\n\n\n\n
- Find outdated passwords<\/li>\n\n\n\n
- Discover reasons behind reduced employee productivity<\/li>\n<\/ul>\n\n\n\n
You can also try filtering out applicants prone to opportunistic attacks when running background checks.<\/p>\n\n\n\n

7 Third-Party Security Risk Management Best Practices<\/a><\/p>\n\n\n\n
Conclusion<\/h2>\n\n\n\n
The key difference between targeted attacks vs common opportunistic attacks is that an opportunistic hacker leverages a chance they\u2019re presented with rather than plans their attack ahead. Any weaknesses they find in your security system can present an opportunity, from misconfigured access permissions to shared passwords and accounts.<\/p>\n\n\n\n

<\/a><\/figure>\n\n\n\nUntargeted attacks can originate from the outside, as with opportunistic ransomware attacks, or from inside your organization, as with opportunistic insiders. To deter opportunistic attackers, you need to gain visibility across your organization\u2019s network so you can see who accesses your critical assets, when, and what they do with them.<\/p>\n\n\n\n
- Record user sessions<\/a> and review them in a YouTube-like player, and use these records as evidence during audits and investigations<\/li>\n\n\n\n
- Monitor and review in real time<\/a> the activity of on-site and remote employees as well as subcontractors to see who does what within your network<\/li>\n\n\n\n
