Received email from ISP saying one of my devices has malware

My dad received a suspicious email from our ISP (mtnl.net.in) The email was from noreply@mtnl.net.in and it had our userid (xxxxxxxx@a i masked it) in the email so it must have come from the ISP itself.

Email details below:

Subject:

“Intimation Regarding Malware/ Virus Infected Systems”

Body:

Dear Sir/Madam, Greetings! It is observed that your device connected with MTNL Mumbai broadband network with broadband number xxxxxxxx@a is infected with Malware. This is as per the analysis of Computer Emergency Response Team -INDIA (Cert-IN), under the Ministry of Electronics and Information Technology. Malware (CNC) is unwanted software that is installed in users system without users consent while user is surfing on the Internet. An attacker or cybercriminal can remotely send commands to such systems which are compromised by malware. These compromised machines can be used to create powerful networks (botnet) of infected devices capable of carrying out distributed denial-of-service (DDoS) attacks, stealing data, deleting data or encrypting data in order to carry out an extortion scheme. The device becomes part of the botnet due to malware/virus installed on it. To secure your devices , Kindly check your devices for malware/ botnet using Antivirus S/w. For more information on malware/botnets and the counter measures kindly visit https://www.cyberswachhtakendra.gov.in. You can also download "Free botnet removal tools". Thanks & Warm Regards, MTNL, Mumbai 

I extracted all links from the email and scanned them via https://www.virustotal.com/ url scanner but all were reported as safe.

Looking online there is a similar question on Quora but different scenario.

NETWORK AT HOME

  • Two mobile phones (Android)
  • One laptop (Windows 10 with Avira antivirus)

QUESTION:

  • Can an ISP really detect this?

  • Should I action on this and what to do?

Postfix | Because When I send a email to Gmail, this is received as spam?

I had installed Postfix with the configuration mode: Internet SIte My file /etc/postfix/main.cf have follow it:

# See /usr/share/postfix/main.cf.dist for a commented, more complete version   # Debian specific:  Specifying a file name will cause the first # line of that file to be used as the name.  The Debian default # is /etc/mailname. #myorigin = /etc/mailname  smtpd_banner = $  myhostname ESMTP $  mail_name (Raspbian) biff = no  # appending .domain is the MUA's job. append_dot_mydomain = no  # Uncomment the next line to generate "delayed mail" warnings #delay_warning_time = 4h  readme_directory = no  # See http://www.postfix.org/COMPATIBILITY_README.html -- default to 2 on # fresh installs. compatibility_level = 2    # TLS parameters smtpd_tls_cert_file = /etc/ssl/private/postfix.pem smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key smtpd_use_tls=yes smtpd_tls_session_cache_database = btree:$  {data_directory}/smtpd_scache smtp_tls_session_cache_database = btree:$  {data_directory}/smtp_scache smtpd_tls_security_level = may # See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for # information on enabling SSL in the smtp client.  smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination myhostname = webserver.com alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname mydestination = smtp.gmail.com relayhost =  mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 mailbox_size_limit = 10737418240 recipient_delimiter = + inet_interfaces = all inet_protocols = all home_mailbox = /home/correo/ #CERTIFICADO DKIM milter_default_action = accept milter_protocol = 2 smtpd_milters = inet:localhost:8891 non_smtpd_milters = inet:localhost:8891 

I has edited the parameter mydestination to the SMTP server of Gmail

mydestination = smtp.gmail.com

Postfix works, I sent a email to my gmail

mail --------------@gmail.com Cc: Subject: title There are message works 

and my Gmail spam tray:

What I have to do for that the email not spam?

P.D: I followed this: https://blog.openalfa.com/como-evitar-que-los-emails-enviados-por-postfix-sean-considerados-como-spam But this doesn’t work.

I don’t want that the email is sent to other SMTP server and this send it to the destination. How to changes the mail address root@server.com to other? Thanks you

How to send messages in the order they were queued, while ensuring that client B does not have to wait until client A has received his message?

I have a simplified producer/consumer pattern implemented below. The code outputs:

“A”

1 second delay

“B”

1 second delay

“A”

1 second delay

“B”

What approach can I take here to get rid of the 1-second delay between different letters?

What I’m looking for is something like

“A”

“B”

1 second delay

“A”

“B”

It’s important, that clients A and B receive the messages in the order the messages were queued in, but I do not want other clients to be blocked while processing for one client takes a really long time. Using two BlockingCollections and two consumer threads is not an option, because the user count is dynamic.

using System; using System.Collections.Concurrent; using System.Threading.Tasks;  namespace ConsumerProducer {     public enum ClientId     {         A,         B     }      class WebSocketMessage     {         public ClientId ClientId { get; }          public WebSocketMessage(ClientId clientId)         {             ClientId = clientId;         }          public async Task LongRunningSend()         {             Console.WriteLine(ClientId);             await Task.Delay(TimeSpan.FromSeconds(1));         }     }      class Program     {         public static BlockingCollection<WebSocketMessage> Messages = new BlockingCollection<WebSocketMessage>();          static async Task Main(string[] args)         {             var consumer = Task.Run(async () =>             {                 foreach (var message in Messages.GetConsumingEnumerable())                 {                     await message.LongRunningSend();                 }             });              ClientId clientId = ClientId.B;             while (true)             {                 // Flip between A and B                 clientId = clientId == ClientId.A ? ClientId.B : ClientId.A;                  Messages.Add(new WebSocketMessage(clientId));                  await Task.Delay(TimeSpan.FromMilliseconds(100));             }         }     } } 

How can I replace a feat that I received as a class feature

I took 2 levels of Monk, for Invisible Fist and free Improved Trip from Passive way. The latter gave me the quite unusable Combat Expertise.

Is there a way to replace it? I know the Dragonborn template makes it possible to replace a feat for a Draconic feat. Unfortunately my DM does not let me become one.

How else can I replace a feat obtained from a class?

Can I travel to Canada? | Received RFE for H1-B transfer petition

I have my current H1-B visa valid upto July-2021 on my passport. However I recently moved to a different team within the same company and hence had to file a H1-B COE petition. But we received an RFE (Request for Evidence) lately and we are currently working with Immigration team to frame the response to USCIS.

With this in my mind, can I still travel to Canada & return back to the US on my current H1-B visa? Please advise.

Thank you.

Received all dependent UK visas but not the primary visa

What could lead to dependents receiving their entry visas before the primary applicant? Main question: Is it true that my application has to be successful before they would issue dependent visas?

I applied from the U.S. for a tier 4 student visa for a PhD program in the UK. What makes my application somewhat unique, perhaps, is that I have 5 dependents coming with me (spouse and 4 children).

I have now received the 5 successful dependent visas via UPS, but mine (the primary or sponsoring visa) has not even shipped yet. I have the return label tracking numbers for all of the 2nd Day Air UPS packages. 5 are delivered (obviously, I have them in hand) but mine has not even been picked up by UPS yet.
