These statistics are based on detection verdicts of Kaspersky Lab products received from users who consented to provide statistical data. Q3 figures According to Kaspersky Security Network: Kaspersky Lab solutions blocked 947,027,517 attacks launched from online resources located in 203 countries. 246,695,333 unique URLs were recognized as malicious by Web Anti-Virus components. Attempted infections by

While investigating a cryptocurrency exchange attacked by Lazarus, we made an unexpected discovery. The victim had been infected with the help of a trojanized cryptocurrency trading application, which had been recommended to the company over email.

Olympic Destroyer worm, Roaming Mantis mobile banker, Operation Parliament cyber-espionage campaign, SynAck ransomware and other notable targeted attacks and malware campaigns of Q2 2018.

In Q2 2018, attempted infections by malware designed to steal money via online access to bank accounts were logged on the computers of 215,762 users, ransomware attacks were registered on the computers of 158,921 unique users.

As researchers we interesting in developmental prototypes of malware that have had limited distribution or not even occurred in the wild. We recently came across one such sample: a macOS backdoor that we named Calisto.

Not long ago, news appeared online of a younger sibling for the sensational vulnerability EternalBlue. The story was about a new vulnerability for *nix-based systems – EternalRed (aka SambaCry). On May 30th our honeypots captured the first attack to make use of this particular vulnerability, but the payload in this exploit had nothing in common with the Trojan-Crypt that was EternalBlue and WannaCry.

In this research we’ll be revisiting the USB port – this time in attempts to intercept user authentication data on the system that a microcomputer is connected to. As we discovered, this type of attack successfully allows an intruder to retrieve user authentication data – even when the targeted system is locked.

The Lamberts is a family of sophisticated attack tools that has been used by one or multiple threat actors against high-profile victims since at least 2008. The arsenal includes network-driven backdoors, several generations of modular backdoors, harvesting tools, and wipers.

Starting from yesterday, many DSL customers in Germany were reporting problems with their routers. Today we saw news, that a malicious attack could be the reason for this widespread problem.

Back in January this year we found a new family of cross-platform backdoors for desktop environments. After the discovery of the binaries for Linux and Windows systems, we have now finally come across the OS X version of Mokes.A.

We found a new wave of different campaigns spreading the initial “Banloader” components in Jar (Java archive). It’s able to run on Linux, OS X, Windows. It’s also able to run under certain circumstances even on mobile devices.

Recently Patrick Wardle published an analysis of a new Backdoor and Dropper used by HackingTeam. It looks like the samples mentioned in the blog were found in-the-wild, so we decided to see how this latest Backdoor works.

Yesterday a blog post on “The Linux Mint Blog” caught our attention. Apparently criminals managed to compromise a vulnerable instance of Wordpress which the project used to run their website. The attackers modified download links pointing to backdoored ISO files of Linux Mint 17.3 Cinnamon edition.

Recently we came across a new family of cross-platform backdoors for desktop environments. First we got the Linux variant, and with information extracted from its binary, we were able to find the variant for Windows desktops, too. Not only that, but the Windows version was additionally equipped with a valid code signing signature. Let´s have a look at both of them.

In December 2014 we discovered a very interesting vulnerability in the Darwin kernel. Using it attackers can send just one incorrect network packet to the victim and the victim’s system (OS X 10.10 or iOS 8) will crash.
