We have been observing a malvertising campaign via Rig exploit kit delivering a cryptocurrency-mining malware and the GandCrab ransomware since July 25. On August 1, we found Rig’s traffic stream dropping a then-unknown ransomware. Delving into this seemingly new ransomware, we checked its ransom payment page in the Tor network and saw it was called Princess Evolution (detected by Trend Micro as RANSOM_PRINCESSLOCKER.B), and was actually a new version of the Princess Locker ransomware that emerged in 2016. Based on its recent advertisement in underground forums, it appears that its operators are peddling Princess Evolution as a ransomware as a service (RaaS) and are looking for affiliates.Read More

In 2017, we saw digital extortion increasingly become cybercriminals’ first and foremost money-making modus operandi. It’s mostly due to ransomware — cybercriminals’ currently most popular weapon of choice, helping them in extorting cash from users all over the world and in hitting big businesses and organizations.
By infecting business-critical systems through their shotgun-style ransomware attacks and thus crippling enterprise day-to-day operations, cybercriminals managed to force big companies to bend to their will. Digital extortion has become the most successful moneymaking venture for cybercriminals, and the most effective in terms of the scale of their victims. Big or small, everyone gets hit, and everyone has to pay.Read More
We encountered a few interesting samples of a file-encoding ransomware variant implemented entirely in VBA macros called qkG (detected by Trend Micro as RANSOM_CRYPTOQKG.A). It’s a classic macro malware infecting Microsoft Word’s Normal template (normal.dot template) upon which all new, blank Word documents are based.
Further scrutiny into qkG also shows it to be more of an experimental project or a proof of concept (PoC) rather than a malware actively used in the wild. This, however, doesn’t make qkG less of a threat.Read More
A ransomware campaign is currently ongoing, hitting Eastern European countries with what seems to be a variant of the Petya ransomware dubbed Bad Rabbit.Read More
