The return of Fantomas, or how we deciphered Cryakl

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.

To crypt, or to mine – that is the question

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.

Pbot: evolving adware

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.

Olympic Destroyer is still alive

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.

A MitM extension for Chrome

Browser extensions make our lives easier: they hide obtrusive advertising, translate text, help us choose in online stores, etc. There are also less desirable extensions, including those that bombard us with advertising or collect information about our activities. These pale into insignificance, however, when compared to extensions whose main aim is to steal money.

VPNFilter EXIF to C2 mechanism analysed

Our colleagues from Cisco Talos published their excellent analysis of VPNFilter, an IoT / router malware which exhibits some worrying characteristics. We’ve decided to look a bit into the C&C mechanism for the persistent malware payload.

Spam and phishing in Q1 2018

The quarter’s main topic, one that we will likely return to many times this year, is personal data. It remains one of the most sought-after wares in the world of information technology for app and service developers, owners of various agencies, and, of course, cybercriminals. Unfortunately, many users still fail to grasp the need to protect their personal information and don’t pay attention to who and how their data is transferred in social media.

Roaming Mantis dabbles in mining and phishing multilingually

In May, while monitoring Roaming Mantis, aka MoqHao and XLoader, we observed significant changes in their M.O. The group’s activity expanded geographically and they broadened their attack/evasion methods. Their landing pages and malicious apk files now support 27 languages covering Europe and the Middle East.

IT threat evolution Q1 2018. Statistics

According to KSN, Kaspersky Lab solutions blocked 796,806,112 attacks launched from online resources located in 194 countries across the globe.

SynAck targeted ransomware uses the Doppelgänging technique

In April 2018, we spotted the first ransomware employing the Process Doppelgänging technique – SynAck ransomware. It should be noted that SynAck is not new, but a recently discovered sample caught our attention after it was found to be using Process Doppelgänging. Here we present the results of our investigation of this new SynAck variant.
