Ransomware: new trends are strengthening cyber attacks
Destructive Ransomware, alternative crypto-coins and greater use of misleading tactics are among the trends used by malicious hackers who have most contributed to “increase” the digital crime market.
A new report from iDefense, an Accenture Security business area, shows how cybercriminals resort to increasingly evolving tactics to avoid detection.
The 2017 Cyber Threatscape Report examines key trends in the first six months of this year, highlighting aspects such as the growth in the number of threat authors as well as the quick expansion of their capabilities due to such factors as the dissemination of “available, customizable and accessible “.
Specifically, there is an increase in the use of cybercriminals to misleading tactics, which include anti-analysis, steganography (a specific type of encryption), and command and control servers used to hide stolen data.
It also highlights the proliferation of sophisticated phishing campaigns, with “baits” that mention invoices, resumes, bank transfers, late payments. In this chapter it is stated that ransomware is aggravating the use of bank trojans as one of the most powerful types of malware through phishing techniques.
The report also highlights the growth of espionage actions and interventions by state-sponsored hackers, the increase of bitcoin washing techniques or the adoption of alternative crypto-coins and the dissemination of so-called DDoS-for-hire botnets.
