China-Backed Hackers Leverage SIGTRAN, GSM Protocols to Infiltrate Telecom Networks

China-Backed Hackers Leverage SIGTRAN, GSM Protocols to Infiltrate Telecom Networks

Nov 20, 2024 Cyber Espionage / Telecom Security
A new China-linked cyber espionage group has been attributed as behind a series of targeted cyber attacks targeting telecommunications entities in South Asia and Africa since at least 2020 with the goal of enabling intelligence collection. Cybersecurity company CrowdStrike is tracking the adversary under the name Liminal Panda , describing it as possessing deep knowledge about telecommunications networks, the protocols that undergird telecommunications, and the various interconnections between providers. The threat actor's malware portfolio includes bespoke tools that facilitate clandestine access, command-and-control (C2), and data exfiltration. "Liminal Panda has used compromised telecom servers to initiate intrusions into further providers in other geographic regions," the company's Counter Adversary Operations team said in a Tuesday analysis. "The adversary conducts elements of their intrusion activity using protocols that support mobile telecommunicati...
New SEC Rules Require U.S. Companies to Reveal Cyber Attacks Within 4 Days

New SEC Rules Require U.S. Companies to Reveal Cyber Attacks Within 4 Days

Jul 27, 2023 Data Breach / Cyber Attack
The U.S. Securities and Exchange Commission (SEC) on Wednesday approved new rules that require publicly traded companies to publicize details of a cyber attack within four days of identifying that it has a "material" impact on their finances, marking a major shift in how computer breaches are disclosed. "Whether a company loses a factory in a fire — or millions of files in a cybersecurity incident — it may be material to investors," SEC chair Gary Gensler  said . "Currently, many public companies provide cybersecurity disclosure to investors. I think companies and investors alike, however, would benefit if this disclosure were made in a more consistent, comparable, and decision-useful way." To that end, the new obligations mandate that companies reveal the incident's nature, scope, and timing, as well as its impact. This disclosure, however, may be delayed by an additional period of up to 60 days should it be determined that giving out such specific...

Monday again. The weekend was meant to be quiet. It wasn't. Last week had poisoned packages, a broken AI helper, and a worm tearing through repos. The ugly part: basic tricks still worked. A chatbot got fooled. A bot token got leaked inside the malware. The same old mistakes showed up again. And while everyone chased the loud stuff, quieter attackers sat in inboxes for months, reading mail and stealing it bit by bit. Lots to cover. Grab coffee. Read up. ⚡ Threat of the Week Miasma Worm Hits 73 Microsoft GitHub Repositories in Supply Chain Attack - Microsoft's GitHub repositories became the latest to fall victim to the ongoing Miasma self-replicating supply chain attack campaign. The incident impacted 73 Microsoft repositories across four of its GitHub organizations, including Azure, Azure-Samples, Microsoft, and MicrosoftDocs. The development prompted GitHub to disable access to those repositories. Miasma is assessed to be a variant of the Mini Shai-Hulud worm that T...

Aug 25, 2025 Cybersecurity News / Hacking
Cybersecurity today moves at the pace of global politics. A single breach can ripple across supply chains, turn a software flaw into leverage, or shift who holds the upper hand. For leaders, this means defense isn’t just a matter of firewalls and patches—it’s about strategy. The strongest organizations aren’t the ones with the most tools, but the ones that see how cyber risks connect to business, trust, and power. This week’s stories highlight how technical gaps become real-world pressure points—and why security decisions now matter far beyond IT. ⚡ Threat of the Week Popular Password Managers Affected by Clickjacking — Popular password manager plugins for web browsers have been found susceptible to clickjacking security vulnerabilities that could be exploited to steal account credentials, two-factor authentication (2FA) codes, and credit card details under certain conditions. The technique has been dubbed Document Object Model (DOM)-based extension clickjacking by independent sec...

Dec 22, 2025 Hacking News / Cybersecurity
Cyber threats last week showed how attackers no longer need big hacks to cause big damage. They’re going after the everyday tools we trust most — firewalls, browser add-ons, and even smart TVs — turning small cracks into serious breaches. The real danger now isn’t just one major attack, but hundreds of quiet ones using the software and devices already inside our networks. Each trusted system can become an entry point if it’s left unpatched or overlooked. Here’s a clear look at the week’s biggest risks, from exploited network flaws to new global campaigns and fast-moving vulnerabilities. ⚡ Threat of the Week Flaws in Multiple Network Security Products Come Under Attack — Over the past week, Fortinet , SonicWall , Cisco , and WatchGuard said vulnerabilities in their products have been exploited by threat actors in real-world attacks. Cisco said attacks exploiting CVE-2025-20393, a critical flaw in AsyncOS, have been abused by a China-nexus advanced persistent threat (APT) actor cod...

This week’s updates show how small changes can create real problems. Not loud incidents, but quiet shifts that are easy to miss until they add up. The kind that affects systems people rely on every day. Many of the stories point to the same trend: familiar tools being used in unexpected ways. Security controls are being worked on. Trusted platforms turning into weak spots. What looks routine on the surface often isn’t. There’s no single theme driving everything — just steady pressure across many fronts. Access, data, money, and trust are all being tested at once, often without clear warning signs. This edition pulls together those signals in short form, so you can see what’s changing before it becomes harder to ignore.

Jan 12, 2026 Hacking News / Cybersecurity
This week made one thing clear: small oversights can spiral fast. Tools meant to save time and reduce friction turned into easy entry points once basic safeguards were ignored. Attackers didn’t need novel tricks. They used what was already exposed and moved in without resistance. Scale amplified the damage. A single weak configuration rippled out to millions. A repeatable flaw worked again and again. Phishing crept into apps people rely on daily, while malware blended into routine system behavior. Different victims, same playbook: look normal, move quickly, spread before alarms go off. For defenders, the pressure keeps rising. Vulnerabilities are exploited almost as soon as they surface. Claims and counterclaims appear before the facts settle. Criminal groups adapt faster each cycle. The stories that follow show where things failed—and why those failures matter going forward. ⚡ Threat of the Week Maximum Severity Security Flaw Disclosed in n8n — A maximum-severity vulnerability ...

Some weeks are loud. This one was quieter but not in a good way. Long-running operations are finally hitting courtrooms, old attack methods are showing up in new places, and research that stopped being theoretical right around the time defenders stopped paying attention. There's a bit of everything this week. Persistence plays, legal wins, influence ops, and at least one thing that looks boring until you see what it connects to. All of it below. Let's go. ⚡ Threat of the Week Citrix Flaw Comes Under Active Exploitation — A critical security flaw in Citrix NetScaler ADC and NetScaler Gateway (CVE-2026-3055, CVSS score: 9.3) has come under active exploitation as of March 27, 2026.

This week is not about one big event. It shows where things are moving. Network systems, cloud setups, AI tools, and common apps are all being pushed in different ways. Small gaps in access control, exposed keys, and normal features are being used as entry points. The pattern becomes clear only when you see everything together. Faster scans, smarter misuse of trusted services, and steady targeting of high-value sectors. Each story adds context. Reading them all gives a fuller picture of how today’s threat landscape is evolving. ⚡ Threat of the Week Cisco SD-WAN Zero-Day Exploited — A newly disclosed maximum-severity security flaw in Cisco Catalyst SD-WAN Controller (formerly vSmart) and Catalyst SD-WAN Manager (formerly vManage) has come under active exploitation in the wild as part of malicious activity that dates back to 2023.

Security, trust, and stability — once the pillars of our digital world — are now the tools attackers turn against us. From stolen accounts to fake job offers, cybercriminals keep finding new ways to exploit both system flaws and human behavior. Each new breach proves a harsh truth: in cybersecurity, feeling safe can be far more dangerous than being alert. Here’s how that false sense of security was broken again this week. ⚡ Threat of the Week Newly Patched Critical Microsoft WSUS Flaw Comes Under Attack — Microsoft released out-of-band security updates to patch a critical-severity Windows Server Update Service (WSUS) vulnerability that has since come under active exploitation in the wild. The vulnerability in question is CVE-2025-59287 (CVSS score: 9.8), a remote code execution flaw in WSUS that was originally fixed by the tech giant as part of its Patch Tuesday update published last week. According to Eye Security and Huntress, the security flaw is being weaponized to drop a .N...

ThreatsDay Bulletin is back on The Hacker News, and this week feels off in a familiar way. Nothing loud, nothing breaking everything at once. Just a lot of small things that shouldn’t work anymore but still do. Some of it looks simple, almost sloppy, until you see how well it lands. Other bits feel a little too practical, like they’re already closer to real-world use than anyone wants to admit. And the background noise is getting louder again, the kind people usually ignore. A few stories are clever in a bad way. Others are just frustratingly avoidable. Overall, it feels like quiet pressure is building in places that matter. Skim it or read it properly, but don’t skip this one.

Another week in cybersecurity. Another week of "you've got to be kidding me." Attackers were busy. Defenders were busy. And somewhere in the middle, a whole lot of people had a very bad Monday morning. That's kind of just how it goes now. The good news? There were some actual wins this week. Real ones. The kind where the good guys showed up, did the work, and made a dent. It doesn't always happen, so when it does, it's worth noting. The bad news? For every win, there's a fresh headache waiting right behind it. New tricks, old tricks dressed up in new clothes, and a few things that'll make you want to go touch grass and never log back in. But you will. We all do. So here's everything that mattered this week — the wins, the warnings, and the stuff you really shouldn't ignore. ⚡ Threat of the Week Tycoon 2FA and LeakBase Operations Dismantled — The infrastructure hosting the Tycoon2FA service, which Europol said was among the largest advers...
