While some organizations may view third party breach usernames and passwords as important indicators to prevent unauthorized access to their own networks, larger organizations are using two factor authentication for securing their perimeters by locking down internet-facing services where the mere availability of these credentials are less actionable. 

Can Audio Deepfakes Really Fake a Human?

Audio deepfakes are the new frontier for business compromise schemes and are becoming more common pathways for criminals to deceptively gain access to corporate funds. Nisos recently investigated and obtained an original attempted deepfake synthetic audio used in a fraud attempt against a technology company. The deepfake took the form of a voicemail message from the company’s purported CEO, asking an employee to call back to “finalize an urgent business deal.” The recipient immediately thought it suspicious and did not contact the number, instead referring it to their legal department, and as a result the attack was not successful.

In the era of data-driven decision making, the value of threat intelligence and interest in establishing or expanding threat intelligence programs is growing rapidly. However, the growing availability and access to data is outpacing the ability of these threat intelligence programs to leverage and operationalize it.

According to a recent Gartner report, “the value of (threat intelligence) services is sometimes constrained by the customer’s ability to afford, absorb, contextualize, and, especially, use the information provided by the services.” ¹

Many organizations use threat intelligence from industry peers to prioritize vulnerability management and assign criticality when there is not enough existing information directly about their organization or their organization’s critical assets. While this is a natural political response to frame the narrative to allow budgetary approval to build certain aspects of the security program, organizations need to defend specific to their own technology stack and assets, incorporate the proper tooling around this stack, and be able to log events at scale. 

If a security program indicates that their industry peers are being targeted by a variety of different threats broken down by industry, the narrative around this argument will likely be a more persuasive argument for non-technical business executives approving budgets.

Threat intelligence feeds have become popular, and a company's ability to track threats outside of its own environment is better than ever. With these improvements though, has come an increasing demand on security professionals to select and manage the right combination of tools to achieve their desired outcomes.

Here is a brief look at the history of the cyber threat intelligence industry, and where we might go from here.

Argument -  fierce, bold, and impassioned - has been at the heart of our American democracy since the founding. British censorship (colonists could speak without prior restraint but then be charged with sedition or libel) compelled the drafters of the Bill of Rights to include freedom of speech as part of the First Amendment to the US Constitution. 

Heated disagreement and even misinformation are as rampant on today’s internet as they were in the taverns and meeting halls of the colonies. This speech is rightly protected. But because of the sacredness of this right, it is disinformation – deliberate attempts by foreign and domestic actors to spread falsehoods in order to achieve a political end – that concerns us here at Nisos and that we leverage our capabilities to fight.

Actionable cyber threat intelligence should inform a security operations center’s prioritization of the most critical applications and infrastructure to the business and threat hunt program in ways a security stack cannot. With hypotheses-led, defined use cases that focus on signatures and more importantly behavior, threat hunting programs can operationalize threat intelligence by mapping threats to data sources and decision matrices that provide alerts and subsequent action. As a deliverable, a SOC can then count the actionable alerts versus the total alerts and, if captured appropriately, a security program can scale by reducing time to respond with fewer resources.

Business needs for all company sizes increasingly require managed production environments to perform critical computational and data storage roles that are often administered by company IT professionals, as well as potentially providing services to both internal and external entities. As a preamble, most common production environments tend to be heavily Linux-based, while most corporate environments are either predominantly Windows or a mixed environment with Windows and MacOS machines. While it should be obvious that the production environment should be heavily protected from arbitrary access from the internet, it can be easily overlooked that protecting company and customer data necessitates security measures against the corporate and other internal networks.

Large companies take robust consultative approaches to integrating  networks and applications post-acquisition. Rarely do acquiring security teams have the resources or cost-effective internal processes to do their own investigative cyber diligence on a pending acquisition.  The most cost-effective option is intelligence analysis conducted “outside of the firewall”, analysis of unique data that combines automation and human investigation to provide timely and accurate insights  into key man risk, network security, negative press, and infrastructure and network vulnerabilities. Informed by this analysis, “on-network” compromise assessments can then provide a comprehensive inspection to enable the acquiring party to move forward confident it is on stable ground from a security perspective.

Deriving actionable intelligence to enhance organizational security is a challenge faced by all global companies and often further complicated by intertwined networks resulting from mergers and acquisitions. With the volumes of data, it’s important to shape a threat hunting program to be able to consume and operationalize data collected from various sources.
