Spam and phishing in Q3 2017

In terms of the average share of spam in global email traffic (58.02%), the third quarter of 2017 was almost identical to the previous reporting period: once again growth was slightly more than one percentage point – 1.05 (and 1.07 p.p. in Q2 2017). As in previous quarters, spammers were quick to react to high-profile events and adapted their fraudulent emails to the news agenda.

ATM malware is being sold on Darknet market

In May 2017, Kaspersky Lab researchers discovered a forum post advertising ATM malware that was targeting specific vendor ATMs. The forum contained a short description of a crimeware kit designed to empty ATMs with the help of a vendor specific API, without interacting with ATM users and their data.

Miners on the Rise

Over the last month alone, we have detected several large botnets designed to profit from concealed crypto mining.

Throughout the time of its existence, it has worked its way up from a primitive Trojan intercepting mTAN codes to an encrypter.

Schroedinger’s Pet(ya)

Earlier today (June 27th), we received reports about a new wave of ransomware attacks spreading around the world, primarily targeting businesses in Ukraine, Russia and Western Europe. Our investigation is ongoing and our findings are far from final at this time. Despite rampant public speculation, the following is what we can confirm from our independent analysis.

Dridex: A History of Evolution

In the several years that the Dridex family has existed, there have been numerous unsuccessful attempts to block the botnet’s activity. The ongoing evolution of the malware demonstrates that the cybercriminals are not about to bid farewell to their brainchild, which is providing them with a steady revenue stream.
