EXECUTIVE SUMMARY: An unseen adversary could stealthily lurk within your networks for months or even years. Methodically reconnoitering, establishing footholds, mapping out critical assets – this is the modus operandi of Advanced Persistent Threats (APTs). These sophisticated, well-resourced actors don’t just strike and disappear. Rather, they entrench themselves within systems while obfuscating their presence as they move towards their ultimate objective; a devastating cyber attack. By the time that a given organization detects an APT, the damage might have already been done. Believe it or not, 80% of organizations have contended with downtime due to APT incidents.

The cybersecurity firm Mandiant has uncovered a resurgence in USB-based malware attacks led by a China-linked hacker group called UNC53. This group has successfully hacked at least 29 global organizations since last year by social engineering employees into using malware-infected USB drives. #cyberhack #cyberbreach #cyberattack #cyberusb #KnowBe4 #cyberinsurance #cyberinsurancebroker #surewise

Day 30/100 Topic: Advanced Persistent Threat An advanced persistent threat (APT) is a sophisticated, sustained cyberattack in which an intruder establishes an undetected presence in a network in order to steal sensitive data over a prolonged period of time. An APT attack is carefully planned and designed to infiltrate a specific organization, evade existing security measures and fly under the radar. Executing an APT attack requires a higher degree of customization and sophistication than a traditional attack. Adversaries are typically well-funded, experienced teams of cybercriminals that target high-value organizations. They’ve spent significant time and resources researching and identifying vulnerabilities within the organization. ●The goals of APTs fall into four general categories: ➼Cyber Espionage, including theft of intellectual property or state secrets ➼eCrime for financial gain ➼Hacktivism ➼Destruction #100daysofcybersecurity #100dayschallenge #100daysoflearning #zetaxcyber

In December 2023, the Russian APT28 hackers were targeting 13 different countries with a new campaign called "GreyEnergy". The campaign was targeting industrial control systems in order to gain access to sensitive data and disrupt operations. The hackers were using a new malware called "GreyEnergy" which is a variant of the "BlackEnergy" malware. The campaign was first discovered by the cyber security firm, Kaspersky. #cybersecurity #malware #hacking #cybersecurity

A suspected China-linked cyber espionage group, Velvet Ant, attacked an unnamed East Asian organization for about three years, using legacy F5 BIG-IP appliances to maintain persistence and evade detection. Responding in late 2023, cybersecurity firm Sygnia identified the use of PlugX malware to collect sensitive information. Velvet Ant employed sophisticated tactics, including disabling security software and using legacy servers for covert communication. This attack is part of broader China-linked espionage activities targeting Asia. https://lnkd.in/erGSB2aJ

A previously unknown advanced persistent threat (#APT) group used custom malware and multiple publicly available tools to target a number of organizations in the manufacturing, IT, and biomedical sectors in #Taiwan. A government agency located in the Pacific Islands, as well as organizations in #Vietnam and the #US., also appear to have been hit as part of this campaign. This activity began in February 2023 and continued until at least May 2023. The #Symantec Threat Hunter Team, part of Broadcom, has attributed this activity to a new group we are calling #Grayling. This activity stood out due to the use by Grayling of a distinctive DLL sideloading technique that uses a custom decryptor to deploy payloads. The motivation driving this activity appears to be intelligence gathering. #Broadcom #Cybersecurity #Cybercrime
