2023-01-10 22:11

Only a quarter of the respondents said they were victims of ransomware attacks in 2022, a significant drop from 64% the previous year. Over the same period, 13% of companies with fewer than 100 staffers were victimized by ransomware, down from 34%. Why the decline? Delinea cited a few possible reasons: One factor may be the disbanding of the Conti ransomware group into smaller factions; another cause might be the greater effectiveness of security tools in preventing attacks; alternatively, it's possible fewer victims are reporting ransomware attacks.

Russian disinformation didn't materially affect the way people voted in the 2016 US presidential election, according to a research study published on Monday, though that doesn't make the effect totally inconsequential. Boffins from New York University, University of Copenhagen, Trinity College Dublin, and Technical University of Munich analyzed more than 700,000 social media posts in April and in October 2016 from Twitter accounts associated with the Internet Research Agency, a Russian influence operation.

Trojan Puzzle attack trains AI assistants into suggesting malicious code
2023-01-10 20:20

Researchers at the universities of California, Virginia, and Microsoft have devised a new poisoning attack that could trick AI-based coding assistants into suggesting dangerous code. Given the rise of coding assistants like GitHub's Copilot and OpenAI's ChatGPT, finding a covert way to stealthily plant malicious code in the training set of AI models could have widespread consequences, potentially leading to large-scale supply-chain attacks.

To mark the January 2023 Patch Tuesday, Microsoft has released patches for 98 CVE-numbered vulnerabilities, including one exploited in the wild and one that's been publicly disclosed.

Popular JWT cloud security library patches “remote” code execution hole
2023-01-10 19:59

One popular use of JSON is the JWT system, which isn't pronounced jer-witt, as it is written, but jot, an English word that is sometimes used to refer the little dot we write above above an i or j, and that refers to a tiny but potentially important detail. Loosely speaking, a JWT is a blob of JavaScript that is used by many cloud services as a service access token.
