This spring marked the fourth anniversary of the malware's first attacks. Against the backdrop of a general decline in ransomware activity (see our report), we decided to return to the topic of Cryakl and tell in detail about how one of the most eye-catching members of this endangered species evolved.
Today, after almost 3 years of waiting, it was finally the day of the trial. In the Netherlands, where the whole case took place, the hearings are open to the public. Meaning anyone who is interested can visit. And it was quite busy.
These summaries are a representative snapshot of what has been discussed in greater detail in our private reports during Q2 2018. They aim to highlight the significant events and findings that we feel people should be aware of.
While the legal status of cryptocurrencies and laws to regulate them continue to be hammered out, scammers are busy exploiting the digital gold rush. Besides hacking cryptocurrency exchanges, exploiting smart-contract vulnerabilities, and deploying malicious miners, cybercriminals are also resorting to more traditional social-engineering methods that can reap millions of dollars.
Way back in 2013 our malware analysts spotted the first malicious samples related to the Trojan-Ransom.Win32.Rakhni family. That was the starting point for this long-lived Trojan family, which is still functioning to this day. Now the criminals have decided to add a new feature to their creation – a mining capability.
In late April we found and wrote a description of CVE-2018-8174, a new zero-day vulnerability for Internet Explorer that uses a well-known technique from the PoC exploit CVE-2014-6332. But whereas CVE-2014-6332 was aimed at integer overflow exploitation for writing to arbitrary memory locations, my interest lay in how this technique was adapted to exploit the use-after-free vulnerability.
This report will examine what is hopefully ransomware’s last breath, in detail, along with the rise of mining. The report covers the period April 2017 to March 2018, and compares it with April 2016 – March 2017.
It was more than a year ago that we detected the first member of Pbot family. Since then, we have encountered several modifications of the program, one of which went beyond adware by installing and running a hidden miner on victim computers.
At Kaspersky Lab we analyze the technologies available on cybersecurity market and this time we decided to look at what OS developers are offering for embedded systems (or, in other words, the internet of things). Our primary interest is how and to what degree these OSs can solve cybersecurity-related issues.
In May-June 2018 we discovered new spear-phishing documents that closely resembled weaponized documents used by Olympic Destroyer in the past. This and other TTPs led us to believe that we were looking at the same actor again. However, this time the attacker has new targets.
