What are Jump Lists? Jump Lists are windows features introduced with Windows 7, and they contain information about recently accessed applications and files. They allow files and applications to be pinned to the taskbar. There are two forms of jump list that can be created in windows. The first form is called AUTOMATICDESTINATIONS-MS. Like its name, these jump lists are created automatically when the users open a file or an application. This jump list is located in the followi

We have recently observed threat actors evolving their procedures in light of Microsoft disabling macros by default in office documents. This new technique would allow threat actors to continue to bypass security controls to infect one or more hosts in an environment. In light of the latest Microsoft Office vulnerabilities, we will likely see broad adoption of macro-less infected documents that will lead to many organizations getting hacked. While Microsoft has shared mitigat

A user account is created in Active Directory for each user in your environment. Over time as users leave the organization, their accounts do not always get removed from Active Directory. As a result, many organizations have an excessive amount of stale user accounts in Active Directory. You can identify a stale account using the last time the password was changed or the user's last login timestamp. Stale user accounts in Active Directory pose a significant risk to the organi

What are Profile Lists? Windows keeps track of user-profiles and their locations in the registry. The profile location is stored under the key below: HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList This registry key contains one subkey for each user profile on a Windows machine. Inside of each of these subkeys is a registry value called ProfileImagePath that holds that user's profile path. You can also see when each subkey was last written and other details abou

Business continuity and disaster recovery (BCDR or BC/DR) is a collection of processes and procedures that assist a company in recovering from a disaster and returning to normal business operations. It is a broad approach that encompasses both IT and commercial operations and tasks in the aftermath of a disaster. BCDR frequently integrates business operations and information technology to decrease catastrophic risks and support organizations in swiftly resuming normal operati

What is Windows Prefetch? Windows Prefetch creates files when a user opens an application on a Windows host. The Windows Operating system will make a prefetch record when an application is run from a specific area for the absolute time. Microsoft introduced prefetch with the Windows XP operating system. The idea behind the prefetch is that it would accelerate the boot process and start-up process. In older versions of Windows, prefetch files were limited to 128 files. With ne

Phishing attacks remain the number one technique used in cyberattacks. Some of the most common phishing attacks leveraged attachments to facilitate the initial infection chain. We disproportionally see Microsoft Office documents and PDF files used to embed the malicious code as far as the attachments themselves go. When we say Microsoft Office documents, we refer to files created by the Microsoft Office suite such as Microsoft Word, Excel, PowerPoint, etc. Historically we wou

As we look across the landscape, we see that cyberattacks continue to succeed in all business sectors. In the cases we have observed, the cyberattack leveraged weak security controls and, as a result, could have been prevented by organizations adopting security best practices. A new study shows that ransomware, phishing, social engineering, denial of service (DoS) attacks, and the business fallout of a data breach rank as the top concerns of global organizations. The recently

Endpoint Detection & Response (EDR) A critical task for most organizations has become setting up advanced threat protection as cyberattacks have skyrocketed and become more sophisticated. Starting with a robust endpoint detection and response system is the first step in this process. Detecting and responding to endpoint threats, also known as EDR, is a cybersecurity process that gathers and analyses data collected by endpoints, usually workstations and servers. As a result, s

Flexibility: A virtual Chief Information Security Officer (vCISO) can be reached immediately via a simple phone call, whether the vCISO is on or off-site (based on what has been agreed upon). Due to the vCISO’s networking expertise, a vCISO can scale up extremely fast. Additionally, a vCISO can oversee security testing, data protection, and much more, depending on the company's needs. Furthermore, it allows companies to hire a qualified vCISO on a temporary or medium-term bas

Cybersecurity is full of buzzwords like XDR, MDR, and EDR. A new buzzword has been stealing the scene: secure access service edge (SASE). Gartner is the leader in trends, and the company that coined the word XDR and MDR has stated, “By 2024, 30% of enterprises will adopt cloud-delivered SWG, CASB, ZTNA and branch office firewall as a service (FWaaS) capabilities from the same vendor, up from less than 5% in 2020.” (Andrew Lerner, 2021) SASE incorporates security technology to
