Facebook phishing campaign abusing National Bank of Serbia’s name

22. November 2022

The National CERT of the Republic of Serbia wishes to inform the citizens that a new phishing campaign is under way, which abuses the name of the National Bank of Serbia. Phishing attempts are initiated from Facebook page named ’’NBS’’, mimicking the legitimate web page of the National Bank of Serbia, whereby the citizens are offered a false possibility to double their Dina Card balance, if they provide required information.

The message reads:

Since the phishing page is created with an intent to collect citizens’ personal data, the advertized reward being fraudulent and not associated in any way with the National Bank of Serbia, the National CERT urges the citizens not to disclose their personal information.

Notification and recommendations of National Bank of Serbia, regarding this fraud, are available at the link.

Phishing scam attempt

7. June 2021

The National CERT of the Republic of Serbia wishes to inform all Internet users of a new ongoing phishing campaign titled „**SPAM** Ulazak u sistem je uspešno završen, svi podaci sa Vašeg uredaja su kopirani. Pročitajte uputstva dalje.“ The phishing message further reads a threatening information about all the user’s data having been copied and locked, and even a video caption of the user been taken, including all of his/her social network contacts. In exchange for the „recovery“ of the stolen data, a Bitcoin payment in the amount of 1400 USD within 50 hours is requested. The message itself does not contain a fake link, but fraudulently influences the user to willingly make a payment in order to recover their data.

The National CERT recommends that all such emails be deleted. Careful scrutiny of similar incoming messages makes it harder for the attackers to take advantage of your lack of attention on the Internet. Users are advised to be particularly watchful when receiving emails from unknown senders, containing grammatical errors, where an immediate action is required from them.

SMS phishing attacks against users of postal services

10. May 2023

The National CERT of the Republic of Serbia wishes to inform the public that a new SMS phishing campaign against users of postal services is under way. A fraudulent SMS is sent to the user, saying that a parcel supposedly could not be delivered to them due to an unpaid customs fee, asking them to open the link contained in the text message in order to retrieve their parcel. Fake links currently in circulation are: https://rs-posta.comhttps://rs-posta.net and

The link from the text message leads to a fake page where the user is asked to fill in their bank or credit card details, which ultimately enables the attackers to clear the victim’s bank account.

The PE „Post of Serbia“ reminds the public that this is not how this company communicates with its users, therefore extra attention is warranted.

This is how the PE „Post of Serbia“ legitimate page looks like:

The National CERT urges all users who have possibly received such SMS neither to open the link contained therein, nor to disclose their personal data, but to delete such text messages permanently.

On the National CERT’s website, several publications about these threats have been made available, including the way current phishing campaigns are being carried out. In addition, our platform „For a Safer Click“ contains interactive content about various cybersecurity topics.

The above fraud can be reported to the „Post of Serbia“ via the official contact center telephone numbers 0700 100 300 and 011 3607 788, on business days from 8h to 20h and on weekends from 8h to 15h, as well as to the National CERT.

New Type of Phishing emails on the Internet via WeTransfer

25. February 2020

A new case of abuse of the Internet page WeTransfer used for free Internet database transfer up to 2GB was detected yesterday. This phishing campaign uses an illegal ascmgpr[.]ir domain posing as WeTransfer website.

Since the ascmgpr[.]ir domain is still active, caution is advised to the users of Internet, to pay attention to all e-mails sent by WeTransfer. Since the contaminated mail looks different than the regular one, the National CERT advises all users to check if the link downloading the content is legitimate and whether or not it leads to domain, before opening it. This can be done by placing the mouse on the Download link without clicking, which then reveals the address of redirection (see picture below). If the domain is not, the content is not safe for downloading.



It is also possible that the users receive similar messages from e-mail address. Such e-mails should not be opened.

Rakhni Trojan - Multifunctional Malicious Software

9. July 2018

The Kaspersky Lab has detected a new type of malicious software called Rakhni Trojan (Trojan-Ransom.Win32.Rakhni). This type of malicious software has multifunctional abilities. It can be run as ransomware, crypto-miner or net-worm depending on the attacker's decision. Initially, it runs content checks on the victim's PC after which the attacker triggers one of the three possible options.

This type of malicious software emerges on the territory of Russia and spreads further via spam and phishing campaigns. It contains e-mails with fake corporate financial documents. Once they have opened the e-mail, users get instructions on how to open the attached PDF file. By clicking on the PDF, the victim launches an executable file written in Delphi which uses a fake Adobe Systems Incorporated digital signature.

If an attacker decides to launch the ransomware option, the user will receive a MESSAGE.txt file with the ransom request (please visit decryption tools).

If an attacker decides to start the crypto-mining option, a VBS script will start mining Monero and Dashcoin cryptocurrency.

If the previous two options are not suitable, the attacker may decide to run net-worm option which allows the Trojan to copy itself on all computers of the local network.
