WordPress powers over 74 million web sites. Neill Feather, President of cybersecurity agency SiteLock, explains the advantages of open supply software program and the right way to stop frequent hacks.
Anybody utilizing the Drupal CMS platform ought to make certain they’ve patched their system as a result of cybersecurity analysts have seen an uptick in assaults concentrating on a vulnerability that was mounted greater than a 12 months in the past.
Lead researcher for Akamai Larry Cashdollar found the assault marketing campaign whereas inspecting the cloud firm’s community assault logs. Cashdollar mentioned cybercriminals have been trying to assault high-profile web sites by leveraging Drupalgeddon2, an unauthenticated distant code execution vulnerability within the Drupal CMS platform that was patched in March 2018.
“The truth that these guys are nonetheless on the lookout for vulnerabilities which can be greater than a 12 months outdated and trying to attempt to exploit methods to get their malicious php malware put in signifies that there should be loads of methods on the market which can be susceptible, that folk haven’t patched,” Cashdollar mentioned in an interview with TechRepublic.
“They’re on the lookout for web sites which have been uncared for,” Cashdollar continued. “It truly is a get up name to individuals who have not patched their methods. When you’ve got a Drupal set up, it is best to have it patched to the newest model. When you’ve got any type of software program like WordPress, Drupal, and Joomla it is best to all the time maintain these patched and updated, particularly when the model you are working is susceptible to a significant code execution vulnerability that is been circulating since March 2018.”

Cashdollar mentioned the state of affairs was considerably fascinating as a result of the individuals behind the assault have been utilizing GIFs to cover their assault.
“I noticed an assault that’s designed to run code that’s embedded inside a .gif file. Whereas embedding code in a picture file is not a brand new assault technique, I have not seen this technique in fairly a while,” he mentioned.
“The assault site visitors does not look like widespread right now, nor does it look like particularly concentrating on a single trade vertical. At the moment, the assault site visitors appears to be directed in direction of a random assortment of high-profile web sites. These guys are most likely going to search for high-profile, unauthenticated distant code execution vulnerabilities like this and doubtless rework their campaigns to focus on these newer ones that is perhaps more moderen and simply modify their code to make use of that vulnerability to have a vector for the an infection.”
Drupal was very proactive about releasing a patch for Drupalgeddon2, sending out an FAQ and different help to ensure the safety flaw was accurately addressed.
In accordance with Cashdollar, he solely noticed a rise in this sort of assault within the final month. Through the use of .gifs, the individuals behind the assault tried to evade detection and infect machines.
He added that this was simply one other reminder for firms to patch all the things as a way to keep up-to-date on all the newest safety features.
“Crucial vulnerabilities will probably be focused, even when their public disclosure date is over a 12 months outdated. When the vulnerability’s exploitation is straightforward, which is the case with Drupalgeddon2, attackers will automate the method of scanning, exploitation, and an infection when there are poorly maintained and forgotten methods. This creates an issue for enterprise operations and net directors, as these outdated forgotten installs are sometimes related to different essential methods — making a pivot level on the community,” Cashdollar wrote in a weblog put up.
“Sustaining patches in a well timed style,” mentioned Cashdollar “in addition to correctly decommissioning servers in the event that they’re not getting used is the perfect preventative measure that directors and safety groups can take.”
