A threat actor known as Muddled Libra is targeting the business process outsourcing industry with persistent attacks that leverage advanced social engineering ploys to gain initial access. "The attack style defining Muddled Libra appeared on the cybersecurity radar in late 2022 with the release of the 0ktapus phishing kit, which offered a prebuilt hosting framework and bundled templates," Palo Alto Networks Unit 42 said in a technical report.

The North Korean nation-state threat actor known as Kimsuky has been linked to a social engineering campaign targeting experts in North Korean affairs with the goal of stealing Google credentials and delivering reconnaissance malware. "Further, Kimsuky's objective extends to the theft of subscription credentials from NK News," cybersecurity firm SentinelOne said in a report shared with The Hacker News.

The spoofed email is cleverly crafted to look as legitimate as possible: it contains the Zelle logo, grammatically correct text, and an authentic link to the firm's web page at the bottom of the email, in the "Security and privacy" footer. What distinguishes this malicious email from legitimate ones is the sender's email address, which is obviously not related to Zelle.

New research from NCC Group and Abnormal Security shows clouds and a bit of silver to line them: Ransomware attacks declined last year, but business email compromises increased - massively for smaller businesses - and a third of toxic emails got through their human gateways. According to risk management firm NCC Group, there was a 5% drop in ransomware attacks last year - from 2,667 attacks in 2021 to 2,531 attacks in 2022 - although between February and April there was an uptick due to LockBit activity during the Russia-Ukraine war.

Social engineering - also known as human hacking - is an expression that encompasses a number of methods and vectors attackers use to manipulate targets into giving away or providing access to sensitive information, or generally performing actions that are against their best interest. To effectively perform social engineering attacks, attackers exploit vulnerabilities in how humans react to specific situations.

The operators behind the BazaCall call back phishing method have continued to evolve with updated social engineering tactics to deploy malware on targeted networks. Primary targets of the latest attack waves include the U.S., Canada, China, India, Japan, Taiwan, the Philippines, and the U.K. BazaCall, also called BazarCall, first gained popularity in 2020 for its novel approach of distributing the BazarBackdoor malware by manipulating potential victims into calling a phone number specified in decoy email messages.

Callback phishing operations have evolved their social engineering methods, keeping old fake subscriptions lure for the first phase of the attack but switching to pretending to help victims deal with an infection or hack. Callback phishing attacks are email campaigns pretending to be high-priced subscriptions designed to lead to confusion by the recipient as they never subscribed to these services.
