- Researchers investigated a site that popped up in between comments on YouTube. The site offered tweaked apps to break into iPhones without having root access. These tweaked apps were promoted in disguise of OnlyFans Premium, Netflix Premium, and Pokemon Go Spoofer Injector. Once downloaded, these apps could download malicious code, display unwanted surveys or prompt victims to signup for availing premium services.
New Threats
The cyberworld is going cuckoo as a new long-term attack campaign was observed. Dubbed CuckooBees, the campaign was launched by the China-linked Winnti hacker group. The notorious APT38 was linked with four new ransomware strains that share code with two other ransomware. A new APT actor—UNC3524—popped up, which is delivering backdoors and stealing Microsoft Exchange emails.
- Threat hunters have documented a fileless malware attack that abuses Windows event logs to stash and launch trojans in the last stage of the infection stage. The attack also employs Cobalt Strike Beacon, NetSPI, and various custom modules.
- 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 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.
- Researchers have shared technical details of two new Go variants of recently found BlackByte ransomware. The first variant was seen-in-the-wild in September 2021 and the second variant, referred to as BlackByte v2, was discovered in February 2022. Both variants employ various anti-analysis techniques, including a multitude of encryption algorithms to stay under the radar.

- Researchers observed a new variant of AvosLocker ransomware that makes use of a legitimate driver file to disable anti-virus solutions. In addition, the ransomware is also capable of scanning multiple endpoints for the Log4j vulnerability using Nmap NSE script. In one instance, the ransomware variant leveraged a flaw in Zoho ManageEngine ADSelfService Plus to gain initial entry.
