Click on “Safari” (1) and click on “Preferences” (2). Choose the “Advanced” tab (3) and click on the “Change Settings” button (4) next to “Proxies”. Check the “Web proxy (HTTP)” checkbox (5).

Proxy Virus (also known as MITM Proxy Virus) is a type of browser-hijacking program that has recently become popular. In order to spread this infection, cyber criminals often use various adware-type applications. In most cases, these infiltrate computers without users' permission. Adware is also likely to deliver intrusive advertisements and record information relating to browsing activity.

The initial adware installation process seems normal. After installation, however, users are presented with a deceptive pop-up message encouraging them to update the Safari web browser. After clicking 'OK', users are presented with another pop-up that asks users to enter account credentials. In this way, users might inadvertently grant adware permission to control the Safari browser. Additionally, rogue installers deploy a 'bash script' designed to connect to a remote server and download a .zip archive. The archive is then extracted and a .plist file contained within it is copied to the LaunchDaemons directory. The .plist file contains a reference to another file called 'Titanium.Web.Proxy.Examples.Basic.Standard'. Two additional scripts ('change_proxy.sh' and 'trush_cert.sh') are executed after the next reboot. The 'change_proxy.sh' script is designed to change the system proxy settings, thereby making it use HTTP/S proxy at 'localhost:8003'. The 'trush_cert.sh' script is designed to install a trusted SSL certificate into the keychain. Cyber criminals responsible for this infection use Titanium Web Proxy - an open-source asynchronous HTTP(S) proxy writen in C Sharp (C#). Titanium Web Proxy it is a cross-platform proxy, meaning that it can run on various operating systems, including MacOS. The purpose of this infection is to hijack search engines. Cyber criminals use it to modify Internet search results. Using a proxy to achieve this is rather unusual, since cyber criminals typically employ fake search engines. They use various browser-hijacking applications to modify settings (e.g., new tab URL, default search engine, homepage) by assigning them to certain URLs. Promoted websites often seem normal and their design is usually similar to Bing, Yahoo, Google, and other legitimate search engines. Yet, fake search engines can generate results that lead to malicious websites. Moreover, noticing that such browser settings have been modified is simple because users continually encounter redirects to dubious sites. Using tools such as Proxy Virus is more difficult for these criminals, and yet also more reliable from their point of view. Cyber criminals also deliver fake search results by modifying the content of legitimate search engines. For instance, if a user attempts to search using the Google search engine, the entire website (URL, header, footer, etc.) is genuine, however, the infection modifies the result section. In this way, users are fed with fake results even though they search using legitimate engines. Ultimately, this behavior can lead to further high risk infections - users might inadvertently visit malicious websites. Additionally, cyber criminals use such tactics to increase the traffic of certain websites, which allows them to generate revenue through advertising. The presence of Proxy Virus significantly diminishes the browsing experience and can lead to further computer infections. As mentioned above, adware-type applications are designed to deliver advertisements (e.g., coupons, banners, pop-ups, etc.). These ads might also redirect to malicious websites and even run scripts designed to download/install other unwanted apps. Therefore, clicking them can also lead to installation of infectious apps. Additionally, ads are delivered using tools that enable placement of third party graphical content on any site. Therefore, they often conceal website content, thereby diminishing the browsing experience. Adware-type apps gather information such as IP addresses, website URLs visited, pages viewed, search queries, and other similar details, which are later shared with third parties (potentially, cyber criminals). These people generate revenue by misusing private data. Therefore, information tracking might eventually lead to serious privacy issues, or even identity theft. You are advised to remove all infections, including adware and Proxy Virus.

There are dozens of adware-type applications and browser hijackers online. Typically, these applications offer 'useful features' in attempts to give the impression of legitimacy and trick users to install, however, the only purpose of these applications is to generate revenue for the developers. Rather than giving any real value for regular users, PUAs cause redirects, deliver advertisements, modify settings, and record information.

How did potentially unwanted applications install on my computer?

Adware and browser-hijacking applications are usually proliferated via intrusive advertisements and a deceptive marketing method called 'bundling' - stealth installation of third party applications together with regular (usually free) software. Developers know that users often rush download/installation processes and skip steps. Therefore, 'bundled' apps are usually concealed behind 'Custom/Advanced' settings (or other sections) of these procedures. By carelessly skipping download/installation steps and clicking on advertisements, many users expose their systems to risk of infections and compromise their privacy.

How to avoid installation of potentially unwanted applications?

To prevent this situation, be very cautious when browsing the internet and downloading/installing software. We strongly recommend that you download your software from official sources only, preferably using direct download links. Third party downloaders/installers are typically monetized using the 'bundling' method, and thus such tools should never be used. Do some research before downloading unknown software just to confirm that it is legitimate and virus-free. Intrusive advertisements typically seem legitimate, however, once clicked, they redirect to dubious websites (gambling, adult dating, pornography, and similar). If you continually encounter these ads and redirects, remove all suspicious applications and browser plug-ins immediately. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.

Would this malware give the 'bad guys' access to victims' SSL traffic? Could passwords and VPN credentials be captured by this route?

OS X v10.5.1 and later include an application firewall you can use to control connections on a per-application basis (rather than a per-port basis). This makes it easier to gain the benefits of firewall protection, and helps prevent undesirable apps from taking control of network ports open for legitimate apps.

Configuring the application firewall in OS X v10.6 and later

Use these steps to enable the application firewall:

  1. Choose System Preferences from the Apple menu.
  2. Click Security or Security & Privacy.
  3. Click the Firewall tab.
  4. Unlock the pane by clicking the lock in the lower-left corner and enter the administrator username and password.
  5. Click 'Turn On Firewall' or 'Start' to enable the firewall.
  6. Click Advanced to customize the firewall configuration.

Configuring the Application Firewall in Mac OS X v10.5

Make sure you have updated to Mac OS X v10.5.1 or later. Then, use these steps to enable the application firewall:

  1. Choose System Preferences from the Apple menu.
  2. Click Security.
  3. Click the Firewall tab.
  4. Choose what mode you would like the firewall to use.

Advanced settings

Proxy (justness) Mac Os X

Block all incoming connections

Selecting the option to 'Block all incoming connections' prevents all sharing services, such as File Sharing and Screen Sharing from receiving incoming connections. The system services that are still allowed to receive incoming connections are:

  • configd, which implements DHCP and other network configuration services
  • mDNSResponder, which implements Bonjour
  • racoon, which implements IPSec

To use sharing services, make sure 'Block all incoming connections' is deselected.

Allowing specific applications

To allow a specific app to receive incoming connections, add it using Firewall Options:

  1. Open System Preferences.
  2. Click the Security or Security & Privacy icon.
  3. Select the Firewall tab.
  4. Click the lock icon in the preference pane, then enter an administrator name and password.
  5. Click the Firewall Options button
  6. Click the Add Application (+) button.
  7. Select the app you want to allow incoming connection privileges for.
  8. Click Add.
  9. Click OK.

You can also remove any apps listed here that you no longer want to allow by clicking the Remove App (-) button.

Automatically allow signed software to receive incoming connections

Applications that are signed by a valid certificate authority are automatically added to the list of allowed apps, rather than prompting the user to authorize them. Apps included in OS X are signed by Apple and are allowed to receive incoming connections when this setting is enabled. For example, since iTunes is already signed by Apple, it is automatically allowed to receive incoming connections through the firewall.

Proxy (justness) Mac Os Catalina

If you run an unsigned app that is not listed in the firewall list, a dialog appears with options to Allow or Deny connections for the app. If you choose Allow, OS X signs the application and automatically adds it to the firewall list. If you choose Deny, OS X adds it to the list but denies incoming connections intended for this app.

If you want to deny a digitally signed application, you should first add it to the list and then explicitly deny it.

Some apps check their own integrity when they are opened without using code signing. If the firewall recognizes such an app it doesn't sign it. Instead, it the 'Allow or Deny' dialog appears every time the app is opened. This can be avoided by upgrading to a version of the app that is signed by its developer.

Enable stealth mode

Enabling stealth mode prevents the computer from responding to probing requests. The computer still answers incoming requests for authorized apps. Unexpected requests, such as ICMP (ping) are ignored.

Firewall limitations

The application firewall is designed to work with Internet protocols most commonly used by applications – TCP and UDP. Firewall settings do not affect AppleTalk connections. The firewall may be set to block incoming ICMP 'pings' by enabling Stealth Mode in Advanced Settings. Earlier ipfw technology is still accessible from the command line (in Terminal) and the application firewall does not overrule any rules set using ipfw. If ipfw blocks an incoming packet, the application firewall does not process it.
