Brute Force Attacks: Denying the Attacker, Not the User

Posted by Heather Howland on May 13, 2019 9:39:49 AM

According to haveIbeenpwned.com, close to 8 billion accounts have been compromised. The site  provides a tool to see if any of your passwords have been compromised and are available on the dark-net. Once passwords are compromised, they are easily exposed to bad actors who can use them for brute force attacks and credential stuffing.

What State-Sponsored Attacks Can Teach Us About Conditional Access

Posted by Nir Yosha on May 3, 2019 11:52:00 AM

People often think that state-sponsored attacks from groups like Lazarus (North Korea), Fancy Bear (Russia) or menuPass (China) only target public federal organizations in Western nations like the U.S. This is simply not the case. In fact, attacks on large financial and retail institutions have increasingly been state-sponsored attacks hoping to create chaos more than just theft. These attacks largely come from U.S.-sanctioned states such as Iran, Russia and North Korea, as these hacking groups have come to realize that attacking private organizations can achieve the same goals as attacking public institutions.

How to Thwart an Attacker’s Attempt to Compromise Credentials and Move Around a Network

Posted by Heather Howland on Apr 18, 2019 2:56:00 PM

In the past year, we have seen numerous publicly traded corporations (Marriott and T-Mobile), airlines (Cathay Pacific and Delta), and tech companies (Facebook and Google+) all breached because of some type of insider threat or compromised credentials. So, it’s no surprise that insider threats and preventing credential compromise are growing concerns for organizations.

Conditional Access Establishes Trust In the Network

Posted by Heather Howland on Mar 15, 2019 9:46:16 AM

Stolen or compromised credentials pose well-known risks to organizations and their employees. And as hackers and other malicious actors become more advanced and sophisticated in their techniques, the global threat is increasing. At a recent IT security conference, I spoke with a customer about an alert (TA18-276A) that the United States National Cybersecurity and Communications Integration Center (NCCIC) released late last year. The alert, titled “Using Rigorous Credential Control to Mitigate Trusted Network Exploitation,” outlines recommendations on how to overcome these challenges. In this blog, I’ll discuss how Conditional Access and detection of malicious use of tools and protocols can address the NCCIC’s recommendations.  

The alert provides information on how Advanced Persistent Threat (APT) actors are using multiple mechanisms to acquire legitimate user credentials. Once acquired, attackers can use the credentials to exploit trusted network relationships, in order to expand unauthorized access, maintain persistence, and exfiltrate data from targeted organizations. Some of the suggested NCCIC best practices for administrators to mitigate these threats include rigorous credential controls and privileged-access management, as well as remote-access control and audits of legitimate remote-access logs.

Three Ways to Limit the Cybersecurity Impact of the Government Shutdown

Posted by Monnia Deng on Jan 25, 2019 10:25:25 AM

UPDATE (Jan. 25): Recent news reports state a deal has been reached to re-open the federal government through Feb 15. The issues outlined in this blog continue to apply to public and private sector organizations.

As many of you may have read in the news recently, the government shutdown has had a negative impact on both federal and enterprise security. Krebs on Security has reported possible consequences of the government shutdown on the talent pool, such as federal employees actively being recruited by the private sector, as well as delays on security clearances. Duo Security’s news arm, Decipher, has also done a great job laying out potential government shutdown impacts on enterprise security, including delays on NIST guidelines and standards, and closure of FIPS validation sites.

6 Tips for Living a Healthy Digital Life and Avoiding Credential Theft This Holiday Season

Posted by Eran Cohen on Nov 29, 2018 7:51:00 AM

Most of us still dream practical, down to earth, old fashioned dreams. And I’d place a bet that not many people, if any, dream about their credentials being stolen.  Almost all of my memories from the last 15 years or so are stored digitally. The majority of my day to day activity is managed online. My online persona is almost identical to my physical one. I imagine that  many of you are in the same situation.

At the recent Gartner Security & Risk Management Summit, analysts presented their findings on the top technologies for information security and their implications for security organizations in 2018. At the event Neil MacDonald highlighted Top 10 Security Projects for Security and Risk Management Organizations. He continues by emphasizing that these are projects with real supporting technologies that CISOs should be exploring.

Advisory: Flaw in Azure AD Connect Software Can Allow Stealthy Admins to Gain Full Domain Control

Posted by Roman Blachman on Dec 12, 2017 9:42:26 AM

Authors: Roman Blachman, Yaron Zinar.
We recently reviewed a customer’s network and found that 85%(!) of all users in the network had some unnecessary administrative privilege. The excessive privilege stemmed from an indirect inclusion in a
protected admin group. Most Active Directory audit systems easily alert on excessive privileges, but will often miss users who have elevated domain privileges directly through domain discretionary access control list (DACL) configuration. We refer to these users as stealthy admins.

Evolving Employee Security Measures from “Weak Link” to “Front Line Defense”

Posted by Ajit Sancheti on Dec 1, 2017 8:09:38 AM

It's easy to think that attackers have gained an unfair advantage over security professionals. The network perimeter has virtually dissolved, compelling enterprises to simultaneously work to keep the bad guys out while tackling multiple insider threats – naïve employees, malicious insiders, careless third parties, and undetected malware or intruders that have already breached network defenses.

The challenge for security teams today? Legitimate users and activities should not be impeded, but determining what activity to block and what to allow is not always easy.
