Hacker trend 3: Trojans as a proven all-purpose weapon
They are still considered the most dangerous form of malicious software and account for 55 per cent of known malware: Trojans. It is particularly difficult for organisations and authorities to defend themselves against this complex all-purpose weapon. Because with their polymorphic design, Trojans repeatedly circumvent technical filters. If employees are not sensitised, they become a gateway for criminals – with drastic consequences.
This is also demonstrated by one of the more recent examples, Egregor. With this ransomware, cyber criminals use the so-called “double extortion” technique. This means that the criminals not only steal sensitive data from organisations, but also threaten to publish it on the internet in order to extort high ransoms from organisations and those affected. In such cases, apart from the financial loss, it is above all your organisation’s reputation that suffers.
At the beginning of 2021, the German Federal Criminal Police Office (BKA), in cooperation with Europol, succeeded in destroying “Emotet”, one of the most dangerous malwares in recent years. However, the success is by no means lasting, as cybercriminals will continue to drive IT managers to despair with new variants – and make organisations pay.
