Many companies are preparing for stricter SEC cybersecurity incident reporting timelines, and final rules from CISA on reporting ransomware payments and attacks on critical infrastructure. Could attackers try to take advantage of that?

The ALPHV ransomware gang has been in the news in throughout 2023, so of course we’re moving into mid-December with developments on that front.

There’s been a lot of speculation about how threat actors might weaponize AI, given the hype around ChatGPT and other LLMs – especially with developments like WormGPT. But what do the criminals themselves think?

“Our MDR team has the skills, expertise and availability to continuously monitor and protect organizations 24/7.” - John Shier, Field CTO #BHUSA @SecWeekly
Lesley Sullivan retweeted
Always a good conversation with @DarkReading! Earlier today @John_Shier, Field CTO, sat down with Terry Sweeney to discuss @SophosXOps research that investigated attacks by 2023’s most prolific #ransomware gangs thus far: Hive, Royal and Black Basta. #BHUSA
That's a wrap on #bhusa, but we're just getting started at #defcon! Don't miss @Sophos' War Stories and AI Village sessions. More on these talks in this @helpnetsecurity write up: helpnetsecurity.com/2023/08/…

Under investigation: During a hunt for DLL sideloading abuse of vmnat.exe, Sophos X-Ops uncovered a campaign targeting an organization in Southeast Asia. Aligning with TTPs previously attributed to the Mustang Panda threat group, we unraveled a complex, sustained intrusion. 1/10

During a recent hunt for mobile malware, our researchers discovered an interesting campaign targeting Iranian bank customers. We found several malicious Android apps which imitate four Iranian banks.

In mid-June, Sophos identified a previously unnoted initial-access campaign targeting IT users through malicious advertising (malvertising), with the goal of gaining access to business environments, possibly to deploy ransomware. (1/8)

Today, Sophos X-Ops published its Active Adversary Report for Business Leaders, which provides real-world insights into attacker behavior and techniques from over 150 cases from our Incident Response team from across 32 countries. Here’s what we found most interesting.

Sophos says ChatGPT's effect on computer security isn't just easier drafting of phishing emails. "We’ve long seen AI as an ally rather than an enemy for defender." It's had success in 3 projects to counter cyberattack technology. #ChatGPT #AI
ALT screenshot with the following text: The first application Sophos tested with the few-shot learning method was a natural language query interface for sifting through malicious activity in security software telemetry; specifically, Sophos tested the model against its endpoint detection and response product. With this interface, defenders can filter through the telemetry with basic English commands, removing the need for defenders to understand SQL or a database’s underlying structure. Next, Sophos tested a new spam filter using ChatGPT and found that, when compared to other machine learning models for spam filtering, the filter using GPT-3 was significantly more accurate. Finally, Sophos researchers were able to create a program to simplify the process for reverse-engineering the command lines of LOLBins. Such reverse-engineering is notoriously difficult, but also critical for understanding LOLBins’ behavior—and putting a stop to those types of attacks in the future.
