Around 2:46am to 2:52am received sms messages.

The card was just replaced earlier this month because the CVC and expiry date scrapped off.

Most of the purchases were for groceries (tap and pay machine). Towards the third/fourth week only, there were some purchases made on Lazada/Shopee. The Lazada/Shoppee APP and transactions were made on X phone.

OTP is sent to Y phone, registered with the bank.

Its really annoying and I am wandering whether the compromise is X phone, Y phone, Lazada/Shoppee App?

Is there any malware app or app to lock certain apps (like messaging, SMS OTP is sent)?

P/S: called the bank about the unauthorised transaction. card has been blocked and replacement on the way.

transaction mainly on mobile. Sreened for malware, nothing.

I suspect is online transactions are the most prone to unauthorised transactions i guess... hmm.gif

Is there any App that can download or buy that can help block or shield certain transaction/messages from being read by third party?

my phone felt a bit buggy for couple of days. and microsoft defended told me got some shit virus detected and removed. after that, I got scared and went to sign up malwarebyte for 2 years... and than the next day kena microsoft charge usd9... trus... call Maybank to repot fraud.


I am suspecting some of those file shared by those massive whatsapp group is very questionable. even though I never open those shared "apk" or other application for sideloading to the car's infotainment system.

Other than that is some pdf or other documents constantly being shared. While I strictly warn my Boss, pls do not ask your other Boss to send me questionable NSFW type material to my phone, since I use it for work, banking and personal... so sus....

are you using android?

any apps that are installed using apk? any apps that are installed outside of the google play store?

screen your apps again, and check the permissions given to apps.

recommend to delete any weird apps, like calculator with extra functions, 3rd party notepad apps, etc.

Ya, using android, older version Note 8. Need to throw already, buttons keep coming out and no longer have any software update. My previous phone (before kong) acting weird like kena hack (a lot of spam calls and OTP messages saying that i subscribed for ....).

I think android phone r really prone to malware.

I saved my credit card info at a lot platform Lazada, Chrome, Facebook, youtube, Apple, Shopee, Google, TnGo etc but never get such case.
I think nothing related to them as they has heavily regulated payment gateway.

Know your stuff. Did you downloaded any sideloading apps?
.apk? VPN shit? remote app? visit public WIFI constantly?

Never download .apk files, mainly on Pdf.

This early morning I tried to purchase tickets from China airline, my CC (Hong Leong) terus blocked the transaction and deactivated my card. Since it was past mid night, takda orang could reactivate my CC, so had to use wise debit card to purchase the tickets.

Last month I could purchase tickets from Shenzhen airline no problem (same price) using the same CC, also past mid night. Don't know why China airline triggered the bank.

Hong Leong's AI is a bit retarded.

Anyway, so far not encountered any problems, I transferred RM 50k for bill payment using credit card via jompay, system just jalan like usual but UOB immediately block, have to get pre-authorization each time.

I downloaded Malware detection apps also, after screen, found nothing. Delete and then install another app to scan but still nothing.

Hardly download any files from whatapp unless i trust the person.

Anyway, transaction done on phone X with my credit card, how did he know to get the OTP from phone Y? Unless, manage to hack both phones?!?

1st replacement - the CVC and expiry date not visible anymore. The bank says, "Okay, replace with same 16 digit credit card number but different CVC and expiry date only."

The only different shopping pattern is that we started to buy stuff from Shoppee in conjuction with PayDay Sale.

I don't think is an inside job by the bank side but more only third party platform or my phone compromised.

may be worth it to do a full factory reset. on both devices.

back up everything, deregister your device from all banking apps.

then do a reset.

what malware detection app are you using? confused.gif

android more prone to malware because of sideloading, a double edged sword.

need to be vigilant especially this day and age, phishing becoming more and more advanced.

Malware detection app - Avast and spyware detector.

Banking app all in phone Z, not an issue. The only issue is that the contact number with bank is registered to my phone Y.

Even split 3 phones still get unauthorised transactions.

The main purpose is to create virtual cards to separate them from your main card number. Both are virtual (main and additional cards of different numbers). No physical card at all.

Main card - number is permanent - can wave only for Samsung Pay and Google Pay - some say Apple Pay support "coming soon".

Virtual cards - can create for single-transaction use OR can create for multiple-use with set transaction amount per useand  set validity period (as long as within main card's validity). Virtual card cannot be used for wave with Samsung/Google Pay.

E.g.  have set up a virtual card for my Hotlink Postpaid for RM100 per transaction and valid same period as my main card.

Another virtual card set up for insurance payment.
*
Good to know that virtual card can be configured with additional features, this way will be safer.

With Samsung Pay / Google Pay, majority of phones are supported.

Thanks for sharing.

No need to use a virtual CC with Google/Samsung/apple pay. They will use a generated virtual CC on the fly. If buy stuff online and they support Google pay, I will choose this option since they won't know my main card number.

I don't have paypal account.

There are 3 phones involved. Phone X did the transaction. Phone Y had the OTP. Phone Z had the Banking Apps. The phone number registered with the bank is Phone Y but the emails are in Phone Z.

The transactions are made on Phone X, mainly on Lazada/Shoppee App.

This is same credit card. Earlier this month, requested for replacement because CVC and expiry date rubbed off. Bank replaced credit card with same credit card number but different CVC and expiry date. Some purchase was made with Lazada/Shopee App during PayDay sale. One week later unauthorised transactions appeared.

Called bank, block card and replacement sent. When they send replacement, the old credit card numbers are discontinued, and I get new card with new numbers. Essentially, is terminated.

how PRO trace transaction.

1. identify the Payment Processor.

2. on bill, read who "Request the Transaction", in your case PayPal.

3. You mention you dont have paypal account. Nothing wrong, i dont have a Maybank account, can a Maybank terminal process my hongleong card? Yes.

4. Block the CARD = this CARD is SAFE. IF you dont find the root cause, this will still haunted you in near future.

5. Go to paypal, raise a ticket, inform un-auth transaction with XXXX card. request investigation.

6. Paypal will told you, "Who, sent your card info, to request the payment"

7. from there you can block the Source, and maybe with enough complain, this "scammer" may be terminated from Paypal.




For me, blocking is not TOP priority. Finding ROOT Cause = TOP MOST important.
this is how you can Completely solve the problem.

WHO, WHEN, HOW, they get your CARD info to request payment.

DOnt blame BANK...
you pass your card to your wife to shop online oversea.... in somecase, small amount, can just auth success with correct card credential.

Its likely your X Phone

Y Phone only receive OTP, so no info to get there to compromise.

OTP is also not a surefire way to validate transactions. Whether 2FA is shown or not, is actually a flag on payment networks, not all payment endpoints need it.

QUOTE

Android gives you that level of granular control of what apps can access.

However, the best bet is still your own discipline and awareness. Sometimes its not even your fault. My card got terminated once without me knowing. The bank called me in the morning to let me know because their fraud detection found it was part of a leak, so they pre-emptively terminated it and re-issue.

QUOTE(ifourtos @ Sep 3 2025, 11:55 AM)
You can just blocked the card but not terminate it..
You need to find root cause... While keeping the account in service
Average ppl common procedure
Terminate card, then socmed cry father mother said Bank security like shit....
*
If your bank is good, by default it will block on suspicious activity, then you call them to unblock after you verify that the transaction was valid. I used to kena a lot for FB ads charges last time.

However if your card is compromised already, its SOP from the bank to terminate it la. A lot of times, scammers already tokenize the card. Even if you resolve the leak on your end, the card can still be charged. Safest bet is to just get a new card number, which is normally done within a week.

I've experienced similar situation like you.

I just received the renewal card of my Ambank debit card. Just activated for 1 day. And next day my card get unauthorised transaction.

I've been using this card since 2019 and never get any unauthorised transaction. So weird.
