Mac computers are becoming increasingly popular in business and enterprise applications. This growing adoption has had one negative side effect: Adversaries are increasingly targeting Macs, hoping that companies buy into the concept of macOS being immune to cyberattack. While macOS does provide advanced security features, these can be defeated by a determined attacker.

On May 24, 2023, industry and government sources detailed China-nexus activity in which the threat actor dubbed Volt Typhoon targeted U.S.-based critical infrastructure entities. CrowdStrike Intelligence tracks this actor as VANGUARD PANDA. Since at least mid-2020, the CrowdStrike Falcon® Complete managed detection and response (MDR) team and the CrowdStrike® Falcon OverWatch™ threat hunting team have observed related historical activity in multiple sectors.

In quick succession at the end of May into mid-June, software developer Progress released three advisories that any customers using its popular managed file transfer (MFT) solution MOVEit should immediately update to the latest release. In this time, they were made aware of three critical vulnerabilities, CVE-2023-34362 on May 31, CVE-2023-35036 on June 9, and CVE-2023-35708 on June 15.

Chinese hackers use DNS-over-HTTPS for Linux malware communication, a new Golang-based Skuld malware strand steals Discord and browser data from Windows PCs, and a massive phishing campaign uses 6,000 sites to impersonate brands.

The ransomware trend continues to run rampant. One in four breaches involve ransomware, and organized crime actors use ransomware in more than 62 percent of incidents. Cyber criminals are taking advantage of these new opportunities to exploit a greatly expanded attack surface: But ransomware is only one small piece that a security leaders has to manage. The threat of ransomware is compounded by a distributed workforce, trends toward technology consolidation, geopolitical upheaval, and budget constraints.

Classifying new and unknown (zero-day) malware has always been a challenge in the security industry as new variants are discovered in the wild at an overwhelming rate.

In a recent development, Russian hackers have declared their intention to launch cyberattacks on the European financial system within the next 48 hours. The announcement was made late on Wednesday, June 14 and came through a video threat posted on the Mash Telegram channel, a very popular channel for Russian news. This operation appears to be a collaborative effort between the hacking groups KillNet, REvil, and Anonymous Sudan.

On June 14th, the Cybersecurity and Infrastructure Security Agency (CISA), Federal Bureau of Investigation (FBI), the Multi-State Information Sharing and Analysis Center (MS-ISAC) along with its international cybersecurity partners released an advisory calling out the various indicators of compromise (IOCs) and tactics, techniques, and procedures (TTPs) being leveraged by the LockBit ransomware operation over the past 3 years.
