Most attacks, be they real or from a penetration test, begin with an attempt to compromise a single system, or user. The compromise of a device or user account gives the attacker a small foothold in an environment that they can use to pivot to other areas and begin their complete takeover of the targeted organization. Defenders use many techniques to try to prevent this including complex passwords, complex usernames and, of course multi-factor authentication (MFA). MFA, when done properly, reduces the risk of credential compromise from phishing and spearphshing significantly.

It is not often applied to security researchers unlocking information encrypted by a major ransomware threat group.

So, what happened? The concept of Web 3.0 was not supposed to be like this.

Will someone tell Microsoft (again) that to lead in the industry means not just following the competition? They seem to have lost that message again as we are hearing that they will require a Microsoft account to set up and use future versions of Windows 11 Pro. This frustrating need to be attached to the internet and beholden to Microsoft just to use your operating system has always been an odd choice to me, but it is Microsoft and when they can’t figure out what to do, they tend to just copy features (and bad ones at that) from Apple or Google.

On December 4th, 1981, then President Ronald Regan signed Executive Order 12333. This Order, further amended by EO13284 in 2003, 13355(2004) and 13470(2008), is what grants and governs the collection of intelligence by Federal agencies.

Management and a monitoring software are ubiquitous in the IT operation industry. They are force multipliers that allow for what are usually small teams to manage a large number of assets. By design they need to have elevated permission to accomplish their intended tasks. The problem is that these permissions also make them targets for attackers. This means that developers of these tools need to take extra steps to ensure that they are not vulnerable to attack or become the thing that compromises a network.
