Distribution of AccessibleSkill
AccessibleSkill is a new malware that has been reported in various attacks worldwide. At the moment the security experts have not been able to identify a single tactic that is being used to infect the targets. We presume that the hackers are using several of the most important methods to carry out malicious campaigns.
A common way of setting browser hijacker attacks is the use of email spam messages. They may directly distribute malicious file attachments containing scripts that lead to an infection. Other cases can utilize complex social engineering tricks and hyperlinks that are specifically made to confuse the intended targets into infecting themselves. Two more scenarios that are used in combination with email messages rely on infected files used as payloads ‒ documents and software installers.
- Infected Software Installers ‒ The criminals craft malicious packages made out of legitimate software installers. They are taken from the official vendor download sites, modified, and then posted on online sites or attached (either as file attachments) or linked in the email messages.
- Infected Documents ‒ They represent dangerous files that usually come in the form of some of the most popular document types: rich text documents, spreadsheets, and databases. When the users open them up a notification prompt will ask them to enable the built-in scripts (macros). If this is done then the malware is installed on the victim computer.
The malware browser plugins can be uploaded to hacker-controlled sites and P2P networks like BitTorrent as well. The hacker operators frequently utilize template design, text, and images to create portals that look like legitimate download sources. They may also use domain names that are very similar to legitimate sites and advertise them via pop-ups or ad networks.
The browser hijacker code associated with the AccessibleSkill can be found in numerous malware toolbars. They are usually made for the most popular web browsers: Mozilla Firefox, Google Chrome, Internet Explorer, Safari, Microsoft Edge. They can be distributed on such download sites or even on the browsers repositories (such as the Chrome Web Store for Google Chrome) using fake developer accounts.
