The SophosLabs Uncut article, Worms Deliver Cryptomining Malware to Web Servers, underscores how easy it is for cybercriminals to leverage bots to discover soft targets. The report explains an automated attack that can deliver a wide range of malicious code to servers that, as a class, tend to lag behind normal update cycles.
Anatomy of a Blended Cyberattack
Once the bots identify potential targets, cybercriminals use their savvy to select victims based on an organization’s scope of sensitive data or intellectual property, ability to pay a large ransom, or access to other servers and networks. The final steps are cerebral and manual: break in, evade detection and move laterally to complete the mission. This could be to quietly sneak around to steal intelligence and exit unnoticed, disable backups and encrypt servers to demand high-roller ransoms, or use servers as launch pads to attack other companies.
“Blended cyberattacks, once a page in the playbook of nation state attackers, are now becoming regular practice for everyday cybercriminals because they are profitable. The difference is that nation state attackers tend to persist inside networks for long lengths of time whereas common cybercriminals are after quick-hit money making opportunities,” said Dan Schiappa, chief product officer, Sophos. “Most malware is now automated, so it’s easy for attackers to find organizations with weak security postures, evaluate their payday potential, and use hand-to-keyboard hacking techniques to do as much damage as possible.”
Sophos explains how blended cyberattacks work in this video, Intercept X for Server with Endpoint Detection and Response (EDR).
Sophos Intercept X for Server with EDR
With Sophos Intercept X for Server with EDR, IT managers at businesses of all sizes now have visibility across an entire estate. This allows them to proactively detect stealthy attacks, better understand the impact of a security incident and quickly visualize the full attack history.
“When adversaries break into a network, they head straight for the server. Unfortunately, the mission critical nature of servers restrains many organizations from making changes, often significantly delaying patch deployment. Cybercriminals are counting on this window of opportunity. If organizations do fall victim to an attack, they need to know the full context of what devices and servers were hit in order to improve security as well as answer questions based on stricter regulatory laws. Knowing this information accurately the first time can help businesses resolve issues much faster and prevent them from a repeat data breach,” said Schiappa. “If regulators rely on digital forensics as evidence of lost data, then businesses can rely on the same forensics to demonstrate their data has not been stolen. Sophos Intercept X for Server with EDR provides this required insight and security intelligence.”
Sophos Intercept X for Server with EDR expands Sophos’ offering of EDR, which was first announced for endpoints in October 2018. Sophos EDR is powered by deep learning technology for more extensive malware discovery. Sophos’ deep learning neural network is trained on hundreds of millions of samples to look for suspicious attributes of malicious code to detect never-before-seen threats. It provides broad, expert analysis of potential attacks by comparing the DNA of suspicious files against the malware samples already categorized in SophosLabs.
With Sophos’ EDR feature, IT managers also have on-demand access to curated intelligence from SophosLabs, guided investigations into suspicious events, and recommended next steps. To maintain full visibility into the threat landscape, SophosLabs tracks, deconstructs and analyzes 400,000 unique and previously unseen malware attacks each day.
