Advanced Persistent Threat feed

The Fitsec Advanced Persistent Threat feed is a collection of data used to identify malware fingerprints and attacks targeted towards an organization. It is designed to be easily integrated into your existing systems and to improve your malware detection capabilities. With our APT-feed, your organization is equipped to possibly stop an advanced attack altogether, or at least minimize the damages to your operation.

What is an APT?

Targeted attacks are often referred to as APTs (Advanced Persistent Threat). The target is usually carefully selected and specific, and it can be a company or an individual office. By using multiple phases to break into a network and limiting the target range, targeted attacks become increasingly difficult to detect.

The attackers usually hold key information about the target organization, which they use to gain access into the network by using multiple different technical and social methods. APTs are commonly long lasting and invisible to the target organization itself. Usually the main goal of an APT is to capture critical information and/or obstruct the operations of an organization by attacking their infrastructure.


Protect your organization from advanced threats with the latest indicators on malicious activity.
The Fitsec APT-feed provides you with data of the latest IOCs (Indicators of Compromise), which is data that is designed to be integrated into various systems in your organizations network infrastructure. IOCs enable you to monitor your network environment for signs of infection or abnormal behavior, before damages are inflicted.

Can we protect against targeted attacks?

Completely protecting against APTs is not possible, however with quick detection and response times you can minimize the damage done to your organization.
To aid quick detection and response times, it is a good idea to educate your staff and raise awareness on how to detect APTs and how to act in the event of an attack.
Other best practices for protection include keeping software up to date, installing antivirus and anti-malware products on all systems, monitoring your networks and utilizing threat intelligence feeds to detect malicious activity in your networks.

It is also best to avoid opening unknown links to websites and to avoid connecting unknown USB-storage devices to your systems, as these can make you vulnerable to attacks.

Has our network been breached?

Suspicious activity includes logins to new or unusual systems or logins during unusual times. Increased network activity during or outside office hours can also be an indicator of a breach. Other indicators of a breach can include systems slowing down, unusual software updates or connection problems.
Also, indicators of an ongoing attack or upcoming breach to gain sensitive information can include unusual calls or emails to your staff.

If you have any reason to believe your network has been attacked or breached, it is best to consult a professional as soon as possible to prevent further damage.
