It uses two new shellcode loaders such as StealthVector and StealthMutant, alongside a backdoor named ScrambleCross. Another ongoing campaign distributing a new variant of Konni RAT has also been found targeting users in Russia. Meanwhile, IoT device manufacturers are on the radar of attackers following the discovery of common injection vulnerabilities in Realtek chipsets.

Top Breaches Reported in the Last 24 Hours

38 million records exposed
Around 38 million records containing data related to Covid-19 vaccination status, Social Security numbers, and email addresses have been exposed following a misconfiguration issue in Microsoft Power Apps. The data leak has impacted American Airlines, Microsoft, JB Hunt, and the government of New York City, Maryland, and Indiana.

South Asia countries under attack
A new espionage campaign targeting public and private companies in South Asian countries is underway. The campaign has been active since July 2020 and uses shellcode loaders such as StealthVector and StealthMutant, along with a backdoor named ScrambleCross. Phishing emails containing malicious LNK files are used as an initial infection vector.

Phishing with UPS.com
A phishing campaign that exploited the XSS vulnerability in UPS.com allowed threat actors to distribute a malicious document through a remote Cloudflare worker. The attack used phishing emails that pretended to be from UPS and stated that a package had an exception and needed to be picked up by the recipient.

US organizations targeted by OnePercent Group
FBI has shared TTPs of OnePercent Group, a threat actor that is believed to be associated with REvil, Maze, and Egregor ransomware groups. Some of the tactics opted by the gang involve the use of phishing emails, Cobalt Strike beacon, RClone, and IcedID trojan.

SAC Wireless attacked
SAC Wireless, a subsidiary of Nokia, has disclosed a data breach following an attack by Conti ransomware. The incident was discovered on June 16.

Triada trojan
A malicious version of FMWhatsApp includes a Triada trojan that can collect data from users’ phones. Depending on the type of information, it can further install modules of other trojans such as xHelper, intercept the login confirmation text, and display unwanted ads.

A new variant of Konni malware
An ongoing phishing campaign, launched in late July 2021, is pushing a new variant of Konni RAT to target users in Russia.
