Apart from understanding the ransomware tactics and techniques beyond encryption, it is equally important to understand how they arrive in the environment. Our recent analysis reveals that majority of ransomware families can be stopped at the exposure layer—web and email. In fact, Trend Micro has blocked more than 66 million ransomware-related spam, malicious URLs, and threats from January to May 2016.Read More
Early this year, we reported that in 2015, Angler came out as the top exploit kit, having contributed 59.5% in the total exploit kit activity for the year. Now, there’s barely any pulse left.
After the arrest of 50 people accused of using malware to steal US$25 million, it is interesting to note that Angler basically stopped functioning. With Angler’s reported inactivity, it appears that cybercriminals are scrambling to find new exploit kits to deliver malware. Angler had been the exploit kit of choice because it was the most aggressive in terms of including new exploits and it was able to apply a lot of antivirus evasion techniques such as payload encryption and fileless infection.Read More
We came across a family of mobile malware called Godless (detected as ANDROIDOS_GODLESS.HRX) that has a set of rooting exploits in its pockets. By having multiple exploits to use, Godless can target virtually any Android device running on Android 5.1 (Lollipop) or earlier. As of this writing, almost 90% of Android devices run on affected versions. Based on the data gathered from our Trend Micro Mobile App Reputation Service, malicious apps related to this threat can be found in prominent app stores, including Google Play, and has affected over 850,000 devices worldwide.Read More
As a known banking Trojan center, it’s not surprising when Brazil’s cybercriminals launch what could be considered “banking Trojans as a service.” In this particular case, a skilled cybercriminal started offering a fully functional banking Trojan and its associated infrastructure for rent, to be used by less-skilled crooks.
This particular threat caught our eye because of its ad, which included demonstration videos on YouTube. Its creator, “Ric”, offers the services of this particular banking Trojan for rent, which costs approximately US$600 for a 10-day period. The service includes a comprehensive, highly capable, and well-designed console, as well as the capability to bypass additional authentication steps used by banks in Brazil.Read More
How do companies regardless of size and industry prepare for ransomware attacks? A recent study revealed that businesses are considering saving up Bitcoins, just in case they get hit by these threats and can recover their confidential files in a short span of time. While we don’t recommend succumbing to the ransom payment as it doesn’t guarantee that you’ll get your files back plus you’ll be prone to more ransomware attacks, we can’t also blame these large organizations and businesses for doing so.Read More
