Critical Security Update: September 4, 2025 (TP-Link, Microsoft, Android, WhatsApp)
Critical Security Update
TP-Link, Microsoft, Android, WhatsApp
Risk 1: Medium
Issue: TP-Link, a popular low-cost router has recently announced a large vulnerability that is already being exploited that allowed remote access AND control of the environment where it is installed. This is across multiple TP-Link devices.
Resolution: TP-Link has released and updated so anybody with an TP-Link device should apply the software and firmware update immediately.
More so, TP-Link is not an enterprise-level solution so any professional in financial services should be looking for a commercial solutions and not a low-cost retail solution.
Risk 2: Low
Issue: Microsoft has announced that their most recent update triggers a minor security issue for non-administrative users. They may experience issues when installing applications locally.
Resolution: Microsoft is working on a full solution. Impacted users may need to seek out an administrator temporarily for installing applications until the patch is available.
Risk 3: High
Issue: Google has announced a large update to its Android platform. This update is device independent and includes 84 updates. This is one of the largest security updates we have seen in a while. Two of these updates are critical.
Resolution: Given that this updates impacts a large number of devices, if you have an Android device, it is suggested you check for updates under device settings and apply immediately.
Risk 4: High
Issue: WhatsApp recently announced a large zero-day vulnerability (publicly known and already being exploited). This allows for remote access to data as well as the potential to intercept calls or piggyback onto calls.
Resolution: An update has been released. Usage of WhatsApp should halt immediately until the update is applied. The update should be available through your operating system’s app store.
