Unprecedented ransomware attacks from North Korean hacking groups have grabbed the attention of researchers. This follows the discovery of four ransomware strains that were used in the wild over the past two years to extort APT38’s victims. The four ransomware in question are Beaf, PXJ, ZZZZ, and ChiChi. In another update, several new malware loaders were registered in the last 24 hours as Winnti’s new Operation CuckooBees campaign surfaced. 

Meanwhile, phishing emails have turned out to be a significant go-to-attack vector in different ongoing attack campaigns that target NHS employees and verified Twitter accounts. The ultimate goal of these campaigns is to harvest credentials from victims.

Winnti steals trade secrets
A newly discovered Operation CuckooBees campaign associated with the Winnti APT group was found stealing intellectual property from several organizations across North America, Europe, and Asia. The campaign had leveraged the Windows Common Log Files System (CLFS) mechanism to evade detection and distribute a variety of new malware loaders, such as a new DEPLOYLOG loader, and different new versions of Spyder Loader, PRIVATELOG, and WINNKIT. 

NSW hit
The Australian state of New South Wales’s (NSW) transport agency revealed that it was impacted by a cyberattack in early April. The attack was launched via the agency’s Authorised Inspection Scheme (AIS) online application system. During this incident, an unauthorized third-party successfully accessed a small number of the application’s user accounts.

NHS employees targeted in phishing attacks
Researchers have detected an ongoing phishing attack campaign targeting the National Health Service (NHS). The campaign uses hijacked NHS email accounts to send credential harvesting links to employees based in England and Scotland. So far, around 1,157 phishing emails used for this purpose have been identified in the attack.

Twitter accounts targeted
Multiple verified Twitter accounts have been targeted in an ongoing phishing email attack operation to collect login credentials from users. These accounts belong to celebrities, politicians, influencers, journalists, and private and public entities. These accounts are particularly sought after by hackers to promote scam campaigns and malicious activities.
