AT&T Employees Bribed to Install Malware onto Company Network

The US government has extradited a man following a criminal scheme targeting AT&T. Until September 2017, the attacker had been paying large sums of money to AT&T employees to unlock cellphones, remove them from the network and install malware onto the network. The staff were found and bribed using Facebook and telephone, one of which received $428,500 over a 5 year period to carry out the criminal acts. It is believed that the company lost more than US $9.5 million over the course of the malicious campaign. This is a strong reminder of the damage that can be caused by insider threats / rogue employees.

WordPress Plugin Maliciously Locks Up Blog Posts

A malicious WordPress plugin called WP Security has been recently been discovered; it has been spotted targeting blog posts and encrypting them, making the content unreadable. This is the first time a plugin has been seen targeting specific posts. Security researchers have said that encrypted blog posts can be recovered from a database backup. WordPress website owners are advised to update all plugins and reset their database passwords to mitigate the risk of these threats. In addition, ensure your WP site is secure and always do a thorough review of any plugin before installing.

Threats

Android Ransomware Spreads Via SMS and Reddit

A new ransomware threat has hit Android devices and could become a serious problem. The ransomware spreads through malicious links dropped in forum posts and SMS messages; once the device is affected, the attacker can then use the victim’s contact list to spread the malware further. Once the ransomware app has been downloaded from the link and the files are encrypted, deleting the app will result in your stolen files being encrypted indefinitely. Security researchers have said that the ransom for files have only been around $100-200, however if the attackers were to target bigger groups, the threat could become very serious. Android users are advised to download applications exclusively from the Google Play store, and avoid random links in forums and SMS messages.

Cisco 220 Switch Vulns Allow Device Take Over

Cisco has released several updates for their 220 small business series switches after 3 critical vulnerabilities were found in the products.

The vulns exist in the web-based management interface of the 220 switch and can be used to completely take over a vulnerable device, while also replacing firmware or installing malware. If you are running Cisco 220 switches, please get updating, but if updating quickly is difficult, this can be easily worked around by temporarily disabling the HTTP/S server.
