ThreatSTOP Premium Feed Spotlight Series: Level Up Your Malvertising Protection with The Media Trust Premium Threat Intelligence Feed

Most malware is often delivered from otherwise legitimate sites. Sometimes this occurs via compromising existing websites, but more often than not, it is by using existing advertising networks as a means to ultimately deliver malware. Quite simply, the attacker buys impressions via existing channels and uses a variety of malvertising tricks to either directly compromise the web browser, or at the least trick the user to installing the malware. This specialized form of malware delivery requires a specialized collection methodology to detect such attacks.

Why Email Is Such a Dangerous Platform (And How to Protect Yourself)

Malicious emails are one of the cyber realm’s most widespread epidemics. Over 215 billion business and consumer emails are received daily, and with such an overwhelming flow of emails arises a very attractive opportunity for threat actors to easily penetrate victims’ online activity and lure them in to giving up credentials, downloading malware and more. According to the Symantec Internet Threat Security Report, one out of 412 emails contains a malware attack.

Although it seems as though cyber awareness is somewhat increasing due to the attempt to keep up with rapid advances in attack techniques, preying on human error continues to be extremely rewarding for threat actors. In retrospect, many email attack victims are dumbfounded when they realize that the email they so willingly acted upon is quite obviously suspicious upon second look. On top of that are highly thought out, sometimes tailored malicious emails, which do not even alert relatively cyber-aware people.

Shlayer the MacOS Trojan Slays its Way into the New Year

While it does not boast any special or complex installation tactics, Shlayer’s distribution vector has made it a tremendous success - the malware has been the most prevalent MacOS strain since its debut two years ago, never falling off its leading spot. Shlayer uses a well-known infection tactic – pressing on a bad link directs the victim to a fake Adobe Flash update.

ThreatSTOP Premium Feed Spotlight Series: Level Up Your Protection with ThreatSTOP NOD, Powered By Farsight

One of the chief problems in cybersecurity is the inherent reactivity of most forms of defense. An attack has to be observed, analyzed and reverse-engineered. THEN, protection can be developed. This means attackers are successful, and inside environments, for a period of time before the attack is noticed, before the indicators for that attack can be extracted, and before a policy can be disseminated to stop it.

There has been a wide variety of research in recent years around this problem. How to speed up the cycle to recognize attacks and to potentially get out in front of attackers to block them before the attacks start. Both my own PhD research and other researchers have noticed that one attribute that is overwhelmingly an indicator of maliciousness in DNS is “newness,” that is to say, the newer a domain is, the more likely that it is bad. More importantly, when a domain is new and otherwise benign, it is rarely in meaningful use except by the organization that’s setting up whatever will go there.

Hostile Domestic Surveillance & Security Automation: A Case Study

Photo Cred: Forbes

 

Last week, I had the pleasure of speaking at Virus Bulletin on the recent news of iPhone (first reported on by Google Project Zero) and Android (first reported on by Volexity) mobile malware being used to target Tibetans (as reported by Citizen Lab) and Uighur Muslims inside and outside the People’s Republic of China. Lots of great research is linked above and you should definitely read it.

Whenever events like these occur, researchers from many organizations are researching pieces of it. If you are interested in Chinese APT attacks against these groups, certainly take a look.

One of the most interesting things to me when looking into these attacks is the sophistication and persistence of the adversary. As vulnerabilities got patched, they reused what pieces they could from their attacks and discovered new vulnerabilities to maintain their ability to action on the surveillance objectives. Some of the tools used indicate relationships to other Chinese APT groups, and certainly these types of attacks could be used against truly foreign adversaries as well.

LIVE BrightTALK Webinar: Stop Watching & Start Blocking, Affordable Machine-Learning Enabled Defense

The chief problem with cyber security is that most of our tools and workforce is geared to waiting for adverse events, detecting those events (sometimes months after the fact), investigating the breach that has already occurred, and then cleaning up. This slow and reactive process ensures breaches happen and security staff us overwhelmed under the noise.

This talk will focus on automation and machine learning techniques that can proactively identify threats seen in the wild based on the latest academic research. This techniques allow organizations to identify suspect infrastructure before it is used to attack them. The key to making this work is infusing machine learning with knowledge of how actual attacks work and the threat landscape. Machine learning without intelligence is merely gussied up mensa math exercises.
