WordFence published an article about plugin spammers some years in the past that specified how the spammers paid $15,000 for just one plugin.
at the same time as that seems like a decent amount of money it must be positioned into context that hyperlinks may be offered for $500 each.
So, getting access to 20,000 sites thru a unmarried plugin creates a large possibility to illicitly sell ratings of links on each site that makes use of that one plugin.
In that situation, a spammer best desires to promote 30 links to recoup their investment, and the rest is pure earnings.
The assault documented by WordFence describes that after the purchase of the plugin, the new owners updated the plugin to advantage access to over two hundred,000 websites that used the plugin.

“On June twenty first, the primary release of show Widgets beneath the new creator went out. Then on June 30th there was a 2d release, model 2.6.1, which included the malicious code… this code allowed the new plugin author… to publish junk mail content on any website walking show Widgets.

moreover, many plugins need to be up to date due to the fact the WordPress middle, Hypertext Preprocessor (the software that WordPress runs on), and lots of popular JavaScript libraries that power subject matters and plugins are all constantly up to date, because of this that plugins and issues additionally want to be updated a good way to maintain their functionality.
most plugins are constantly evolving and enhancing their usefulness. It’s ordinary for plugins and topics to be frequently up to date, so it is able to be a caution sign if a plugin has stopped being updated.
