Each time organizations shore up their network defenses, cybercriminals devise new and innovative ways to up the cyber attack ante. That's actually the rationale behind malware crypting - the process of making malicious programs, apps, and files appear harmless to anti-malware and intrusion detection solutions.
The first time the BlackCat ransomware gang breached Reddit's network last February, they phished an employee to hack into the target network. This time, according to a ReversingLabs detailed report, they successfully dropped BlackCat onto the company's systems and threatened to release its data if it fails to pay the ransom.
The beginning of the month of June, according to CleanINTERNET, marked the emergence of several zero-day attacks targeting vulnerable MOVEit servers to exfiltrate confidential data. MOVEit Transfer is a managed file transfer software that supports file and data exchange.
ReliaQuest named LockBit one of the most effective and undoubtedly most prolific currently active ransomware groups today. In fact, the malware topped their latest ransomware quarterly list for the first three months of 2023, a continuation of their 2022 observation.
Threat actors are quite adept at changing tactics once the cybersecurity community or law enforcement catches up to them. That is evident in the recent resurgence of malvertising though no longer through users' browsers as in the past.
Organizations get bombarded with countless attacks from every direction, including via their supply chain. FortifyData's recent record of the top third-party data breaches in 2023 brings to light how multidirectional threat sources can be. In one of the data breaches on the list, AT&T disclosed in March 2023 that threat actors accessed the information of approximately 9 million wireless accounts through the telecommunication company's marketing vendor.
Last year, several governments reportedly used the NSO Group's spyware Pegasus to exploit a zero-day vulnerability in WhatsApp to spy on journalists, opposition politicians, and dissidents via their mobile devices. Apple quickly addressed the issue by launching more powerful data protection features.
Google ad or search engine optimization (SEO) poisoning has long been a favored threat actor tactic to spread malware. A recent Secureworks study of Bumblebee, which comes in the guise of a software installer, proved that once again.
The more dangerous browsing the Internet becomes, the more tools to address cyber threats emerge in the market. Virtual private network (VPN) service usage, for instance, gained ubiquity due to the ever-increasing number of data privacy intrusions.
