We discovered a phishing campaign targeting South Korean websites and users’ credentials using the watering hole technique. Labeling the campaign Soula, cybercriminals injected a malicious JS code in at least four websites for a fake login pop-up to appear at intervals before they can continue using the pages.Read More

We identified a new exploit kit we named Novidade that targets home or small office routers by changing their Domain Name System (DNS) settings via cross-site request forgery (CSRF), enabling attacks on a victim’s mobile device or desktop through web applications in which they’re authenticated with. Once the DNS setting is changed to that of a malicious server, the attacker can execute a pharming attack, redirecting the targeted website traffic from all devices connected to the same router.Read More
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
Reconnaissance plays a vital role in criminal operations, and some groups go to great lengths to investigate their targets’ systems. A recent example is the Andariel Group, a known branch of the notorious Lazarus Group. Last month, we tracked new scouting techniques coming from Andariel, used mainly against South Korean targets.Read More
Our Cyber Safety Solutions team identified a malicious Chrome extension we named FacexWorm, which uses a miscellany of techniques to target cryptocurrency trading platforms accessed on an affected browser and propagates via Facebook Messenger.
FacexWorm isn’t new. It was uncovered in August 2017, though its whys and hows were still unclear at the time. Last April 8, however, we noticed a spike in its activities that coincided with external reports of FacexWorm surfacing in Germany, Tunisia, Japan, Taiwan, South Korea, and Spain.Read More
