If you look at common attack vectors and especially Initial Access Broker attacks, there are a few parts of the attack chain which stand out. These are the pivot through some form of communication/collaboration app to the phishing landing page. These apps are also often part of insider threats where someone might use their own personal email, OneDrive, or other web/app-based app to exfiltrate information they want outside of an organization. Many companies are very exposed to this either through a lack of tools, skilled staff or being oblivious to the exposure.

Using a famous idiom, it looks like the shoe is on the other foot as BreachForums has found themselves the victim of a data breach and release of data. The breach took place in November of 2022 and culminated with the arrest of one of the owners of the forum. The responsible parties were able to attack and exfiltrate data from the site including user information, IP addresses and internal messages sent between users and the forum.

Supply chain attacks are all the rage right now (although certainly not new). These attacks are part of what appears to be a multi-pronged shift in the threat landscape. While attacks on the endpoint and users are still happening, we are also seeing expanded efforts in targeting edge devices, networking equipment, and an increased focus on open-source repositories. Recently a new campaign was discovered that is leveraging open-sourced software supply chain attacks in an effort to target the banking sector.

After a recent attack on Federal Civilian Execute Branch (FCEB) Agencies by an APT (Advanced Persistent Threat) group currently suspected of being a nation-state group from China, (whew that was a long start), It has come to the attention of some cloud researchers that these signing keys are not just useful for attacking Exchange Online. According to cloud security company Wiz these MSA Keys can be used to forge tokens for anything that relies on Microsoft Azure AD (Entra ID) Identity services.

Last week Microsoft, the FBI, and CISA made disclosed several attacks on Federal Civilian Executive Branch agencies and other targets of a campaign that appeared to be driven by a new threat group out of China. The attack we detected and tracked down using internal logging available to the GCC low-side tenants and with the help of Microsoft. Fortunately, GCC (Government Cloud Computing) Low Side is not supposed to contain or pass any classified information. It is intended to be used by government agencies and contractors that do not need or have authorization to access anything more than routine sensitive information. This does not reduce the seriousness of the attack and does beg the question on how well the tenants were secured by the cybersecurity teams involved, but at least nothing National Security related was compromised.

The UEFI (Unified Extensible Framework Interface) was the replacement for the old BIOS (Basic Input Output System). It was intended as an improvement to the underlying systems on a motherboard (also called mainboard) the motherboard controls communication between all components connected to it from CPUs, to memory, to GPUs, disk or solid-state drives, network cards… you get the picture. The old BIOS was limited and also susceptible to compromise in a number of rather simple ways. By moving to UEFI systems could become more complex without issues potential hardware conflicts, the UEFI structure was also much faster than the BIOS system meaning that as overall computing increased in speed the underlying controls for different components was up to the task.

It seems that an unnamed FCEB agency had their Outlook Web Access (Exchange Online) environment compromised by a new threat group that is current being attributed to China. The attack and the group were disclosed by CISA and the FBI. With the detection of the FCEB email compromise, Microsoft also identified a much larger espionage campaign involving the newly identified group which includes some 20+ organizations. The timing of the attack is concerning due to it coinciding with a recent NATO meeting.

If I have said it once, I have said it a thousand times; attackers are cunning. The adage that attackers are lazy has nothing to do with strategic, tactical, or technical knowledge. They understand the landscape and, in many cases, better than the organizations they are attacking do. Because of this deep understanding of their target environment, they also know to be on the lookout for special purpose entities. In this case we are talking about Security Researchers. Security researchers are a special target for attackers and when they can leverage an existing opportunity to target and potentially compromise them, they are going to take it.

Diver Signing requirements in Windows is a feature that is intended to help prevent the Windows Operating system from being compromised through malicious software posing as legitimate drivers. The policy was implemented way back in early versions of the 64-bit flavor of Windows XP and became a defacto security policy very quickly after that. Since its implementation and enforcement threat groups have found multiple ways around this policy including the use of compromised certificate issuing groups, purchasing actually legitimate certificates, and certificate theft.

Social engineering efforts via voice calls (Vishing) is nothing new. The use of phone calls for malicious activity is pretty old and include such popular scams as extended car warranties, IRS collection attempts, and the ever popular “there is a complaint against you”. These are just a few of the consumer scams that have been in play and are still in play. On the corporate side there are even more which target general employees and support personnel to either gain entry or enable some form of financial fraud. Sadly, this pivot is also seriously under managed by most organizations, with few providing any preventative training and most not testing this attack vector to determine exposure.
