![]() ![]() Read our full APT Group Profile on Fancy Bear. FANCY BEAR (APT28), a Russia-based attacker, uses phishing messages and spoofed websites that closely resemble legitimate ones in order to gain access to conventional computers and mobile devices.Read our full APT profile on Goblin Panda. This China-based adversary uses two Microsoft Word exploit documents with training-related themes to drop malicious files when opened. GOBLIN PANDA (APT27) was first observed in September 2013 when CrowdStrike discovered indicators of attack (IOAs) in the network of a technology company that operates in multiple sectors.Here are some notable examples of APTs detected by CrowdStrike: Unexpected information flows, such as anomalies in outbound data or a sudden, uncharacteristic increase in database operations involving massive quantities of dataĬrowdStrike currently tracks well over 150 adversaries around the world, including nation-states, eCriminals and hacktivists.Unexpected or unusual data bundles, which may indicate that data has been amassed in preparation for exfiltration.Widespread presence of backdoor Trojans.Unusual activity on user accounts, such as an increase in high-level logins late at night.In addition to spear-phishing campaigns that target organization leaders, symptoms of an advanced persistent threat attack include: Since advanced persistent threats use different techniques from ordinary hackers, they leave behind different signs. Research and Threat Intel Blog Characteristics of an APT Attack ![]() Want to stay up to date on recent adversary activities? Stop by the Research and Threat Intel Blog for the latest research, trends, and insights on emerging cyber threats. The network can remain compromised, waiting for the thieves to return at any time. They may use tactics like a denial-of-service (DoS) attack to distract the security team and tie up network personnel while the data is being exfiltrated. They then extract, or “exfiltrate” it without detection. To prepare for the third phase, cybercriminals typically store stolen information in a secure location within the network until enough data has been collected. ![]() Additional entry points are often established to ensure that the attack can continue if a compromised point is discovered and closed. They may also establish a “backdoor” - a scheme that allows them to sneak into the network later to conduct stealth operations. They move laterally to map the network and gather credentials such as account names and passwords in order to access critical business information. Once initial access has been gained, attackers insert malware into an organization’s network to move to the second phase, expansion. If several executives report being duped by a spear-phishing attack, start looking for other signs of an APT. The email may seem to come from a team member and include references to an ongoing project. Email attacks that target specific individuals are called “spear-phishing.” One indication of an APT is a phishing email that selectively targets high-level individuals like senior executives or technology leaders, often using information obtained from other team members that have already been compromised. In the first phase, advanced persistent threats often gain access through social engineering techniques. ![]() Most APTs follow the same basic life cycle of infiltrating a network, expanding access and achieving the goal of the attack, which is most commonly stealing data by extracting it from the network. To prevent, detect and resolve an APT, you must recognize its characteristics. Cyber Espionage, including theft of intellectual property or state secrets.The goals of APTs fall into four general categories: They’ve spent significant time and resources researching and identifying vulnerabilities within the organization. Adversaries are typically well-funded, experienced teams of cybercriminals that target high-value organizations. An APT attack is carefully planned and designed to infiltrate a specific organization, evade existing security measures and fly under the radar.Įxecuting an APT attack requires a higher degree of customization and sophistication than a traditional attack. 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. ![]()
