What is Win32/Injector.ASR virus?

Win32/Injector.ASR is ransomware-type malware. It looks for the documents on your disk drives, encrypts it, and then asks you to pay the ransom for receiving the decryption key. Besides making your documents inaccessible, this virus additionally does a lot of harm to your system. It alters the networking setups in order to stop you from reading the elimination guidelines or downloading the anti-malware program. In rare cases, Win32/Injector.ASR can even block the setup of anti-malware programs.

Win32/Injector.ASR Summary

In total, Win32/Injector.ASR ransomware activities in the infected computer are next:

  • Behavioural detection: Executable code extraction – unpacking;
  • At least one process apparently crashed during execution;
  • Dynamic (imported) function loading detected;
  • Sample contains Overlay data;
  • Possible date expiration check, exits too soon after checking local time;
  • Creates RWX memory;
  • CAPE extracted potentially suspicious content;
  • The binary contains an unknown PE section name indicative of packing;
  • The binary likely contains encrypted or compressed data.;
  • Authenticode signature is invalid;
  • Behavioural detection: Injection (Process Hollowing);

Ransomware has actually been a horror story for the last 4 years. It is difficult to picture a more harmful virus for both individual users and corporations. The algorithms used in Win32/Injector.ASR (generally, RHA-1028 or AES-256) are not hackable – with minor exclusions. To hack it with a brute force, you need more time than our galaxy currently exists, and possibly will exist. But that malware does not do all these unpleasant things instantly – it can require up to several hours to cipher all of your documents. Therefore, seeing the Win32/Injector.ASR detection is a clear signal that you have to start the clearing process.

Where did I get the Win32/Injector.ASR?

Usual ways of Win32/Injector.ASR spreading are standard for all other ransomware variants. Those are one-day landing sites where victims are offered to download and install the free program, so-called bait e-mails and hacktools. Bait emails are a pretty new tactic in malware spreading – you receive the email that mimics some regular notifications about shipments or bank service conditions modifications. Within the email, there is a malicious MS Office file, or a link which leads to the exploit landing site.

Malicious email spam

Malicious email message. This one tricks you to open the phishing website.

Preventing it looks fairly easy, but still needs a lot of recognition. Malware can hide in different spots, and it is better to prevent it even before it goes into your PC than to rely on an anti-malware program. Basic cybersecurity awareness is just an important thing in the modern world, even if your relationship with a PC stays on YouTube videos. That can save you a lot of money and time which you would certainly spend while looking for a fixing guide.
