When an attacker compromises a maintainer’s credentials or takes over a dormant package, they publish a malicious version and wait for automated tooling to pull it into thousands of projects before anyone notices. William Woodruff made the case for dependency cooldowns in November 2025, then followed up with a redux a month later: don’t install a package version until it’s been on the registry for some minimum period, giving the community and security vendors time to flag problems before your build pulls them in. Of the ten supply chain attacks he examined, eight had windows of opportunity under a week, so even a modest cooldown of seven days would have blocked most of them from reaching end users.

Purple: They feature a boss
Extenders today can support single, dual or tri-band Wi-Fi, and they will tell you the maximum speeds they support on all of their available bands. For example, one dual-band device might support 600Mbps speeds over its 2.4GHz band and up to 1300Mbps over its 5GHz band, for a combined maximum speed of 1900Mbps. For the best performance, you’ll want to go with a Wi-Fi extender that has the highest speeds possible (and those, as you might expect, tend to cost more). Some extenders even support Wi-Fi 7, giving you the latest in wireless technology for higher bandwidth, faster internet speed and lower latency.
