Email phishing and scam call campaigns made cyber weather in April unsettled

Information security now!

In April, cyber weather included rays of spring sun but also spells of rain. Email phishing and scam call campaigns made cyber weather unsettled, but in terms of malware attacks, the month was sunnier than March as the number of related reports decreased slightly. This cyber weather report also includes our review of TOP 5 threats updated four times a year.

Reasons causing rainy cyber weather included phishing campaigns that targeted corporate email accounts and resulted in data breaches. During the past month, we have seen at least secure email-themed campaigns and messages fraudulently representing Adobe and Microsoft OneDrive. We recommend that organisations start using multi-factor authentication, because it would have protected accounts in almost all cases reported to us.

Scams and phishing campaigns also caused cyber weather to be changeable. Especially scam calls using caller ID spoofing caused the rightful holders of the numbers trouble and inconvenience. Scams have employed the numbers of both businesses and private individuals. Traficom continuously cooperates with Finnish telecommunications operators to prevent caller ID spoofing. This collaboration was also presented at the information security event RSA Conference in the United States in April where the NCSC-FI, the Finnish National Bureau of Investigation and Elisa gave a joint presentation about the matter.
