This is one of the main findings of the report “Spam and phishing in the second quarter of 2017” of Kaspersky Lab.

The attack on the ransomware program WannaCry it affected more than 200.000 computers across the globe resulting in a massive panic, and spammers immediately took advantage of the opportunity.

One of the main trends in the last three months is the number of bulk mailings directed at corporate networks.

Kaspersky Lab experts point out that most attacks on the corporate sector have financial goals.

Overall, the volume of malicious bulk shipments increased by 17%, according to new Kaspersky Lab report.

"In the second quarter of the year, we found that the key trends in spam and phishing attacks continued to evolve. The use of WannaCry in mass missions proves that digital criminals are very careful and react directly to international events. In addition, digital criminals began to focus more on the B2B sector, considering it profitable. We expect this trend to continue to evolve and the total number of corporate attacks and their variety will expand, "said Darya Gudkova, Spam Analyst Expert of Kaspersky Lab.
