A recent extensive report by the European Police Office (Europol) on cybercrime confirms that the global Covid-19 pandemic is being heavily abused by cybercriminals. It is therefore important to be familiar with the tools that hackers have recently used and to know what to protect themselves from.
Cybercriminals continue the proven tricks, such as ransomware, during the global Covid-19 pandemic, but at the same time adapt their tactics to new opportunities. Thus, it not only spreads extortion viruses, but also grows, for example, the cloning of SIM cards and other attacks on mobile phones.
Mobile security threats
SMS + phishing = SMishing
From e-mails, the interest of attackers is shifting to mobile phones, so the number of attacks through fraudulent SMS messages is growing.

Through SMS, iMessage or other messages, they will send you, for example, information about the delivery of the shipment, with a link that will ask you to fill in the data.

The chances are even higher if the attacker knows the names of your superiors, colleagues or the names of the department where they work. Add to that a fictional story, in which, for example, you will be asked to generate a one-time password for logging in to the VPN. This opens the way for the company's internal data.
