Vulnerabilities and exploits

Our growing dependence on technology, connectivity and data means that businesses present a bigger attack surface than ever. Targeted attackers have become more adept at exploiting their victims’ vulnerabilities to penetrate corporate defences while ‘flying under the radar’.

The authors of malware use various techniques to circumvent defensive mechanisms and conceal harmful activity. One of them is the practice of hiding malicious code in the context of a trusted process. Typically, malware that uses concealment techniques injects its code into a system process, e.g. explorer.exe. But some samples employ other interesting methods. We’re going to discuss one such type of malware.

Gaza cybergang is an Arabic politically motivated cyber criminal group, operating since 2012 and is actively targeting the MENA (Middle East North Africa) region. Gaza cybergang attacks have never slowed down, recent targets by the group does seem to be varied in nature, attackers do not seem to be selectively choosing targets, but rather seeking different kinds of MENA intelligence.

The latest Patch Tuesday (17 October) brought patches for 62 vulnerabilities, including one that fixed СVE-2017-11826 – a critical zero-day vulnerability used to launch targeted attacks – in all versions of Microsoft Office. The exploit for this vulnerability is an RTF document containing a DOCX document that exploits СVE-2017-11826 in the Office Open XML parser.

We took the most popular dating apps and analyzed what sort of user data they were capable of handing over to criminals and under what conditions.

On October 10, 2017, we identified a new Adobe Flash zero day exploit used in the wild against our customers. The exploit was delivered through a Microsoft Office document and the final payload was the latest version of FinSpy malware.

Kaspersky Lab Industrial Control Systems Cyber Emergency Response Team (Kaspersky Lab ICS CERT) publishes the results of its research on the threat landscape for industrial automation systems for the first six months of 2017.

We’re already used to the fact that complex cyberattacks use 0-day vulnerabilities, bypassing digital signature checks, virtual file systems, non-standard encryption algorithms and other tricks. Sometimes, however, all of this may be done in much simpler ways, as was the case in the Microcin malicious campaign.

A little while back we were investigating the malicious activities of the Freakyshelly targeted attack and came across spear phishing emails that had some interesting documents attached to them. They were in OLE2 format and contained no macros, exploits or any other active content.

Results that had been obtained during research that we discussed in a previous article called for a more detailed analysis of the security problem, but now from within medical institutions (with the consent of their owners, of course). The analysis allowed us to work on mistakes and give a series of recommendations for IT experts who service medical infrastructure.

Corporate information security services often turn out to be unprepared: their employees underestimate the speed, secrecy and efficiency of modern cyberattacks and do not recognize how ineffective the old approaches to security are. And if there is no clear understanding of what sort of incident it is, an attack cannot be repelled. We hope that our recommendations about identifying incidents and responding to them will help information security specialists create a solid foundation for reliable multi-level business protection.

The threat from ransomware continues to grow. Between April 2016 and March 2017, we blocked ransomware on the computers of 2,581,026 Kaspersky Lab customers. In May, we saw the biggest ransomware epidemic in history, called WannaCry.

According to KSN data, Kaspersky Lab solutions detected and repelled 342, 566, 061 malicious attacks from online resources located in 191 countries all over the world.

Since 2014, Kaspersky GReAT has been providing threat intelligence reports to a wide-range of customers worldwide, leading to the delivery of a full and dedicated private reporting service. Prior to the new service offering, GReAT published research online for the general public in an effort to help combat the ever-increasing threat from nation-state and other advanced actors.

The first half of 2017 began with two intriguing ransomware events, both partly enabled by wormable exploit technology dumped by a group calling themselves “The ShadowBrokers”. These WannaCry and ExPetr ransomware events are the biggest in the sense that they spread the quickest and most effectively of known ransomware to date.
