email security Linux server You've probably trained your team to look for red flags. Odd sender names, urgent language, mismatched links. But a well-crafted spoofed email won't trip any of those wires. It looks legitimate, sounds legitimate, and often comes from a domain that passes every automated check you throw at it. . Attackers know exactly how humans scan an inbox. They design around it. This guide walks you through the techniques attackers use to slip a spoofed email past both your filters and your users and what...

Security Vulnerabilities cisa kev vulnerability prioritization
cisa kev vulnerability prioritization Most Linux teams don't struggle to find vulnerabilities anymore. They struggle to decide which ones deserve attention first. Between daily scanner results, vendor advisories, and hundreds of new CVEs each month, the challenge isn't visibility—it's prioritization. . To solve this, organizations typically lean on the National Vulnerability Database (NVD) and CISA’s Known Exploited Vulnerabilities Catalog. But these aren’t competing lists. They answer two entirely different questions. While the...

security advisory vulnerability GNOME is officially shortening its standard vulnerability disclosure window from 90 days to 30 days, a change that impacts upstream maintainers, downstream Linux distributions, and system administrators in how they handle software vulnerabilities. The policy shift, announced by long-time security coordinator Michael Catanzaro , addresses modern software patching realities and a growing influx of automated submissions. .

Today, Git servers are responsible for deployment pipelines, API tokens, SSH keys, package repositories, and the automation scripts that push code directly.

data privacy automation Every system admin has lived through the same Monday morning ritual. A queue of forty tickets, half of them password resets, permission errors, or disk space warnings that any experienced technician could resolve in under two minutes. The other half require actual judgment. For years, automation promised that software would eventually sort the two apart on its own. That promise is now being tested in production Linux environments. . Early results are reshaping how IT teams think about tier-1...

cyber threatemail securitybotnetPostini Report Reveals 91% of Emails Classified as Spam Amid Surge
No, you're not imagining things. You have been getting a lot of spam lately. That's because digital miscreants are using contaminated images and stealthy malware to unleash unsolicited email at unprecedented levels, according to new research from San Carlos, Calif.-based Postini Inc. and UK-based Sophos. Attackers use these tactics to hijack computers and turn them into spam relays, often without the user's knowledge. "Bot activity is the major driver here," said Daniel Druker, Postini's executive vice president of marketing. "Bot-infected machines become part of these zombie PC armies that are used to push out spam." . Postini has watched spam levels spike by nearly 60% in the last eight weeks, and Druker said 91% of all email is now spam. Over the past 12 months, the daily volume of spam rose by 120%, he added. Postini monitors 10 million users across 36,000 businesses worldwide. Of that number, the average user gets seven wanted emails a day, while Postini blocks 77 unwanted emails a day. "That's for the average user," he said. "This is an all-time high, and it shows that spammers are increasingly aggressive and sophisticated in their techniques."

The spam flood is rising, contributing to a reduction in the usefulness of e-mail, a market research firm said Wednesday. Unsolicited e-mail from con artists, virus writers and advertisers accounts for 38 percent of the 31 billion e-mails sent each day in North America this year, up from 24 percent in 2002, International Data Corp., said in a report on web mail and spam. In addition, Internet service providers and makers of anti-spam products report that spam represents from 50 percent to 95 percent of all inbound Internet e-mail, IDC said. That's triple the 15 percent to 30 percent levels reported two years ago. The growing spam avalanche has contributed to a reduction in the usefulness of e-mail. Other factors include the increasing cost of storing and managing e-mail and the growing use of instant messaging. The number of spam sent on an average day is 11 billion, compared with 4.5 billion in 2002, IDC said. In comparison, the number of person-to-person emails currently sent each day and in 2002 is 12 billion and 10.5 billion, respectively. Despite these sobering numbers, filtering tools are improving and doing a better job at intercepting spam before it reaches the inboxes of businesses and consumers, IDC analyst Mark Levitt said. Those tools include desktop software, appliances attached to corporate networks and e-mail filtering offered by service providers.

When we finished, he started checking his other messages. All of a sudden, there was DeeDee, a voluptuous vixen in a plunging red tank top and Daisy Duke shorts, smiling sheepishly from the computer screen. I stared at her for a moment, then at my son. He blanched and raised his hands as if he were in a stickup. "I swear! I don't even know the woman!" he said, in Clintonesque denial.

Spam has become so bad in the US that even advertisers have admitted that restrictions are needed. The Direct Marketing Association (DMA), which once opposed any federal anti-spam legislation, says it will now lobby for federal and state laws to control the growth of million-message batches of emails. A daily flood of spam vexes consumers and internet service providers (ISPs) alike, whose attempts to block it are circumvented by stealthy emailing technology, says the DMA, which has 4,700 members. Jerry Cerasale, the DMA's vice president for government affairs, told Reuters that the sheer volume would swamp the medium, rendering it useless.
