You Only Need $750 of Equipment to Pilfer Data From Satellites, Researchers Say

Researchers found that many satellite communications, including sensitive data from cell phone carriers and militaries, are transmitted unencrypted. A study from UCSD and the University of Maryland revealed that half of the analyzed signals were vulnerable, allowing interception of communications like calls and texts. The researchers used a simple $750 setup to collect this data, warning that companies underestimated potential threats to satellite security. Fixed vulnerabilities have since been confirmed for some affected organizations.

Over 100 VS Code Extensions Exposed Developers to Hidden Supply Chain Risks

Over 100 VS Code extensions leaked access tokens, allowing potential distribution of malicious updates, risking over 150,000 installations. Wiz security identified 550 hard-coded secrets across more than 500 extensions, including major service providers' secrets. Users are advised to limit extensions and enforce scrutiny to mitigate risks. Additionally, a threat actor, TigerJack, published malicious extensions disguised as legitimate ones to exploit unsuspecting developers, reinforcing the vulnerabilities in extension security across platforms. Microsoft is enhancing security measures but warns of risks outside its marketplace.

AI Models Can Acquire Backdoors From Surprisingly Few Malicious Documents

AI models can develop backdoor vulnerabilities from just 250 malicious documents, contrary to previous belief that larger models require proportional amounts. Research shows models of varying sizes, from hundreds of millions to billions of parameters, learned the same backdoor behavior from a small number of poisoned examples. This vulnerability can facilitate actions like generating gibberish on encountering trigger phrases. While the risk is evident, successful defenses exist with adequate clean training data, indicating the need for improved security practices against targeted data poisoning attacks.

Too Salty to Handle: Exposing Cases of CSS Abuse for Hidden Text Salting

Cisco Talos reports on hidden text salting in emails—using CSS to conceal irrelevant content for evasion of spam detection. The technique recently highlighted shows frequent use in spam versus legitimate messages. Four key areas where salt is inserted include the preheader, header, attachments, and body of emails. Common methods involve manipulating CSS properties like font size, visibility, and display, complicating detection efforts. Hidden text salting undermines email security solutions and requires enhanced filtering and detection strategies to mitigate risks effectively.
