Unprotected database exposes data
An unprotected database in China has exposed private data of almost 1.8 million Chinese women. The information exposed in the data leak includes names, ID numbers martial status, political details and education details of women. Researchers found the database was left publicly available without any password protection. The leaky database also contained URLs to photos, BreedyReady status and a ‘HasVideo’ field. The ‘HasVideo’ status implies that women are monitored. It is not clear whether the database is related to a dating app, a government registry, or another organization or company.

WordPress sites are under attack
Hackers are exploiting a cross-site scripting vulnerability in abandoned cart plugin to target WordPress-based shopping sites. They are exploiting the ‘Abandoned Cart Lite for WooCommerce’ plugin to install backdoor malware and infect other vulnerable sites. The exploit code is distributed via URL shortening services like ‘bit.ly’.

Emotet trojan evolves
Malware authors have enhanced the capabilities of the infamous Emotet trojan. The banking trojan which has been active since 2014, has now evolved into a polymorphic malware that can deliver a custom variant for every victim. This enables the malware to entirely bypass signature-based security solutions. The evolved malware uses a couple of tricks to gain persistence on victims’ computers. In the first method, the malware leverages two unique and large sets botnets - Epoch1 and Epoch2 - to further the attack process. However, in the second method, a phishing email is used to facilitate the spread of Emotet to other computers.

New phishing campaign
Researchers have come across a new and creative phishing campaign that tricks even the most vigilant users into giving away their login credentials to attackers. For this, the cybercriminals are creating a malicious web page that mimics the look and feel of a normal browser window such as iOS Safari. To further the attack process, they created a fake Airbnb page that prompted users to authenticate using Facebook login. 

Yatron ransomware
Security researchers have discovered a new ransomware called Yatron. It is widely promoted on Twitter. The ransomware spread using the EternalBlue and DoublePulsar NSA exploits. It attempts to delete encrypted files if a payment is not made within 72 hours.

A new variant of Ursnif
Researchers have unearthed a new variant of Ursnif trojan which applies different, stealthier infection tactics for propagation. Researchers refer to this technique as ‘last minute persistence’ - a method of installing malicious payloads without being detected by antivirus software. Phishing emails are used to spread the malware variant.
