I have an Android (5.0.1 with December 2015 patches). My problem is with Chrome (latest version as per Google Play Store). Which has malicious redirect going on to hidcptqmerifcusymaqddcomolsujibeptsmycmqsrwgrcmywshgnfpjhcc.com

I have scanned the phone with both McAfee and Kaspersky security and no malware is detected. However The redirect is going on.

I suspect a JS file in the browser cache which after cleaning stops redirect for sometime (a day at best).

Any ideas how i can collect a sample before i reset my phone?

  • Are you using an open wifi or maybe a compromised network? Try connect via cellular or another wifi network. Also check if there's a proxy or VPN enabled. Try a different browser if all fails. – billc.cn May 24 '16 at 18:47

Firstly, go into Chrome -> Settings -> Search Engine and check the search engine. There is a malicious search engine bug that google is yet to fix involving JS execution via the Default Search Engines feature.

Then, grab everything from /data/data/com.android.chrome/. The chrome cache is in a directory named cache under this directory.

Next, wipe the entire directory from your phone manually and do a full factory reset.

  • Search engine is google.com I'm unable to view the folder using inbuilt file explorer (Samsung). I've enabled show hidden files and file extension both. Do I need to use ADB to view these? Only folder with com. Android.Chrome is under android directory and have no files (empty folders leading to download folder which is also empty.) – Parth Maniar Jan 15 '16 at 8:07

Are you facing this problem while using a wifi connection? If yes, please make sure other devices connected to the same wifi router are working properly. I am experiencing a similar issue in my home. My desktop computer with Fedora 23 is affected, together with all wifi devices sharing the same router. I have read in the avgforums that manually resetting the dns settings of modem resolves this issue, butI haven't tried it yet.

  • It wont help because this is not a DNS issue. DNS hijacks would return a false IP address for a requested url, such as google.com. But in this case here google.com is redirected to a different url. – Potaito May 24 '16 at 19:15
  • @potAito That doesn't rule out DNS-based attacks. An attacker could temporarily take control of a domain and issue a (permanent) redirection to another site. – Rob W May 25 '16 at 8:20
  • @RobW Hm you mean taking control of the name server responsible for a domain? – Potaito May 25 '16 at 14:18
  • That's a possibility, though it would be much easier (for an attacker) to have an open "free" WiFi network and handles DNS queries. – Rob W May 25 '16 at 23:15
