For years, IPv4 was the only proxy type that really mattered for anyone running automation off a Linux box. IPv6 was the protocol everyone said they’d migrate to, but almost nobody actually did. In 2026, that’s finally starting to shift. . The problem is that most admins stick with IPv4 out of habit. They know it; it’s what their tooling defaults to, and they don’t see a reason to change. Some are overpaying for addresses they don’t need. Others would quietly break their scrapers, scripts, or...

Researchers recently identified another wave of malicious packages on PyPI linked to the broader Mini Shai-Hulud campaign, a worm-like supply chain attack that spread through trusted software packages. On the surface, the packages looked no different from thousands of others published to the repository each week. . Instead of trying to break into a target network directly, the attackers hid malicious code inside software that developers were already using. A few downloads are all it takes....

IronWorm steals credentials and uses them to spread beyond the original victim, turning developer access into a supply chain risk. . A new campaign targeting npm has evolved past simple credential theft. Researchers identified IronWorm, a self-spreading threat. It harvests high-value Linux development secrets—SSH keys, cloud tokens, package publishing credentials. One compromised workstation becomes a launchpad for downstream supply chain attacks. This is not a get-in-and-get-out operation....

The romanticized image of the digital nomad – a laptop on a sun-drenched balcony – rarely accounts for the actual friction of maintaining a professional development environment on the move. . The friction is amplified with Linux. We are looking for a setup that respects our kernel configurations, handles volatile network handovers, and maintains a strict security posture without the hand-holding of a consumer-grade OS – so, put simply, more than just a laptop and a sunny deck. The hardware is...

Cron has existed in Unix and Linux environments for decades, handling backups, cleanup scripts, patching jobs, log rotation, monitoring tasks, and other maintenance work that administrators do not want to run manually. Most Linux servers rely on it constantly, which is exactly why attackers continue abusing it for persistence after a system has already been compromised. . Persistence through cron is not complicated. Attackers do not need a rootkit or advanced malware framework to maintain...

Email Security: Uncovering Spam Tactics with Digital Signatures

Bulk emailers are digitally signing unsolicited messages in hopes of bypassing popular filtering programs, but updated software has been modified to detect the trick. The trick was noted on several security lists, as the number of junk email messages sporting digital signatures has apparently increased. Digital signatures are used in email to attest to the validity and integrity of an email message; any changes to the message's text break the signature and can thus be detected. The new spam tactic was probably introduced to fool a popular open-source email filtering program known as SpamAssassin, said Rand Wacker, director of product strategy and planning for email software maker Sendmail. Wacker said the openness of the program's development allows spammers to develop tricks to fool the software. "Since SpamAssassin is built in a very transparent way in how it does its filtering, we see a lot of spam that is directly targeted at getting past SpamAssassin," Wacker said. Sendmail's own spam program, Mailstream, wouldn't be fooled by the technique because it doesn't give better scores to signed email messages. Filters frequently use a scoring system to evaluate whether a particular message is spam or legitimate. The link for this article located at ZDNet is no longer available. .
