The SOC Emergency Room Faces Malware Pandemic

To keep users and networks healthy and secure, security teams need to mimic countries that have taken on COVID-19 with a rapid, disciplined approach.

To protect populations from COVID-19, countries are facing unforeseen circumstances and taking extreme measures in response. Everything is moving fast, but we can see that countries that took decisive measures early have slowed the virus's spread.

Security professionals can learn from the healthcare industry new ways to protect their own organizations from hackers, who are out in full force. 

We in the security arena are also inundated with finding increasing and more severe vulnerabilities. To maintain business continuity in this quarantined era, organizations are allowing – or mandating – their employees to work from home and access the organization's business assets from afar. 

Attackers are exploiting the high volume of remote users logged into the organization, presenting a new, very distributed and volumetric, baseline of remote logins. This makes it very hard to identify unusual remote logins and makes it harder to detect credential theft cases; devices that are used to log in for the first time are no longer an anomaly, and so may not be identified. This is the new normal with user behavior and access patterns that have never been seen before, so most organizations are in the area of experiencing "unknown unknowns." They don’t even know what they don’t know.

Additionally, many employees are not security trained and can be attacked by quite simple social engineering methods as they work from home. Spear phishing (with weaponized emails), credit theft of remote user credentials, and phishing campaigns are on the rise.

And not only are doctors and nurses understaffed and overworked in hard-hit areas, so are SOC and IT teams. SOC rooms are now "distributed SOC rooms" and some SOC employees are ill or quarantined. Teams already strapped for staff are making do with even less and in difficult circumstances.

In the real world, countries which have successfully taken on COVID-19 have moved rapidly, identifying those who carry the virus and separating them form the healthy population quickly and effectively. In our IT organizations, we need to adopt the more disciplined, centralized approach. Steps we should take:

  • Act quickly. Identifying our vulnerabilities (vulnerable, untrained for security, employees working from home, stressed out SOC teams) and putting protections in place before attacks get out of control. Don't look backwards on what happened, but rather, look forward to prevent issues before they can occur.
  • Centralized, disciplined security monitoring and controls over distributed environments with focus on the sensitive assets and employees.
  • Find and isolate the infected hosts early – automated security investigation and response actions with focus on phishing, spear phishing, and other credential theft and account takeover activities. Quarantine and quick remediation prevent the spread and keep the majority of users healthy and happy.

In one area our cyber world has an advantage over real life emergency rooms – today it's possible to automate much of the work of security analysts. Imagine if we could provide doctors and nurses with robotic assistants who could take on some of the tasks of the ER team, without needing breaks or getting sick. Advanced AI such as natural language processing (NLP), which automates incident investigations, can lower the burden on our security teams and enable them to fight the big fight against cyber attackers triumphantly.

An authentication flaw was found in ceph in versions before 14.2.20. When the monitor handles CEPHX_GET_AUTH_SESSION_KEY requests, it doesn't sanitize other_keys, allowing key reuse. An attacker who can request a global_id can exploit the ability of any user to request a global_id previously associa...
