Telecommunications networks are a proving ground for cybercriminals and their malware, according to Lastline's Global Threat Intelligence Network. The company recently released the Malscape Monitor report for telecom for the fourth quarter of 2017. It is based on examination of the 100 latest malicious samples and statistical data for threats seen in the 30 days prior to the report. The firm found that one out of every 370 submissions from telecom networks was malicious and evaded typical security controls. That compares to one in 500 from the overall global sampling. Likely explanations, according to the firm, are that telecom companies are attacked more often than the other types of companies or that security in telecom networks is better and thus they find more malicious files than general networks before submission to Lastline.
