Internet users have been receiving e-mails informing them about the possibility of claiming a tax refund. This scam is particularly dangerous considering that its victims may lose all the money from their bank accounts. This time, the scam has been targeted at clients of PKO BP.

The e-mail purports to come from the Polish Ministry of Finance. The victim is assured that they are eligible for a tax refund following the last calculations of their fiscal activity. To claim the refund, the victim needs to file a tax refund claim form, which is attached to the e-mail.

Google Chrome has been used in an attack on Internet users. Cybercriminals have been convincing users to install Chrome Web Store extensions that promise free movies.

Installing such an extension involves a risk: instead of movies, the victim is redirected to a fake site that displays malicious ads (malvertising).

Malicious ads display false information about the device being infected. By clicking on the provided link, the user downloads a program that alerts them of nonexistent viruses; however, a payment is required in order to remove them.

Malicious ads can also be used to infect the victim’s computer with ransomware or use its processing power to mine cryptocurrency.

Cybercriminals are impersonating the Polish division of TNT Express Worldwide. The company’s clients have been receiving e-mails containing an electronic invoice for a completed transport of equipment from Walter Kompressortechnik Polska.

According to AVLab, the e-mail is sent from Sweden and passes through an improperly secured SMTP server. The information is sent from a nazwa.pl server.

It is best to delete this e-mail immediately without opening the attached file, as it will most likely infect your device.

The WhatsApp users are being warned about new “text bomb” messages that can cause their iOS and Android handsets to break down and stop working properly.

According to the security experts, the phones receiving the “text bomb” message are unable to open it properly, leading the app to shut down. The dangerous messages are being spread in two varieties. The first one contains a laughing emoji, and a “Read more” text. The second one features a black dot followed by the words “if you touch the black point then your WhatsApp will hang”. Tapping on the “Read more” or the black dot causes the phone to freeze and, eventually, to shut down entirely.

A new piece of ransomware locks the files of infected computers until its victims play a round of the popular battle-royale shooter, PlayerUnknown’s Battlegrounds (PUBG).

The malware, called "PUBG Ransomware", was first discovered by MalwareHunterTeam. Like other types of ransomware, it works by encrypting the user’s files to make them inaccessible until the victim does something that will decrypt them. Unlike other types of ransomware, this one does not involve the extortion of money, but simply wants the victim to play PUBG for an hour.

According to the MalwareHunterTeam, PUBG ransomware works by scanning the computer’s running processes for the “TslGame.exe” process, which assumedly triggers whenever the  PUBG g

The JavaScript contains obfuscation maneuvers that prevent it from being detected by security programs. It collects information

A yet unknown group of scammers is abusing the Biedronka discount store brand. The offer is tempting – a voucher worth of 50 PLN for shopping in the store – which can be “easily obtained” by making one single bank transfer of 5 PLN.

The security experts from Cert Polska believe that this is one of the most dangerous phishing attacks. If the victim is tempted by the offer and enters the website www.bony-biedronka.com, he or she will be asked to make the money transfer by using a fake Dotpay service. By doing so, the victim unknowingly grants the fraudsters full access to his or hers bank account.

The fake Dotpay website is confusingly similar to the original, and also uses the SSL certificate issued by Let's Encrypt. Money lose occurs a

The unknown group of cyber criminals, impersonating the Przelewy24 payment platform, have flooded the OLX portal with tempting offers.

The scheme is simple, the fraudsters are looking for so-called bargain hunters, offering equipment up to 80% cheaper than market prices. If the transaction takes place, the buyer/victim is asked to cover the shipping costs via the InPost company. For this purpose, the victim receives a link to the fake Przelewy24 payment panel, which is confusingly similar to the original. However, the choice of payment methods is much smaller than in the original one. The buyer can choose only from several banking login panels belonging to mBank, PKO BP, BZ WBK, Millenium and Alior Bank.

The vigilance of the victim is dormant,
