Weekly Recap: Outlook Add-Ins Hijack, 0-Day Patches, Wormable Botnet & AI Malware

Weekly Recap: Outlook Add-Ins Hijack, 0-Day Patches, Wormable Botnet & AI Malware

Feb 16, 2026 Cybersecurity / Hacking
This week’s recap shows how small gaps are turning into big entry points. Not always through new exploits, often through tools, add-ons, cloud setups, or workflows that people already trust and rarely question. Another signal: attackers are mixing old and new methods. Legacy botnet tactics, modern cloud abuse, AI assistance, and supply-chain exposure are being used side by side, whichever path gives the easiest foothold. Below is the full weekly recap — a condensed scan of the incidents, flaws, and campaigns shaping the threat landscape right now. ⚡ Threat of the Week Malicious Outlook Add-in Turns Into Phishing Kit — In an unusual case of a supply chain attack, the legitimate AgreeTo add-in for Outlook has been hijacked and turned into a phishing kit that stole more than 4,000 Microsoft account credentials. This was made possible by seizing control of a domain associated with the now-abandoned project to serve a fake Microsoft login page. The incident demonstrates how overlooke...
New Apache backdoor serving Blackhole exploit kit

New Apache backdoor serving Blackhole exploit kit

Apr 27, 2013
A new sophisticated and stealthy Apache backdoor meant to drive traffic to malicious websites serving Blackhole exploit kit widely has been detected by  Sucuri recently. Researchers claimed that this backdoor affecting hundreds of web servers right now. Dubbed Linux/Cdorked.A , one of the most sophisticated Apache backdoors we have seen so far. The backdoor leaves no traces of compromised hosts on the hard drive other than its modified httpd binary, thereby complicating forensics analysis. All of the information related to the backdoor is stored in shared memory.  The configuration is pushed by the attacker through obfuscated HTTP requests that aren't logged in normal Apache logs. The HTTP server is equipped with a reverse connect backdoor that can be triggered via a special HTTP GET request. This means that no command and control information is stored anywhere on the system. ESET researchers  analyzed the binary and ...
Apple Weakens iOS 10 Backup Encryption; Now Can Be Cracked 2,500 Times Faster

Apple Weakens iOS 10 Backup Encryption; Now Can Be Cracked 2,500 Times Faster

Sep 23, 2016
After the iPhone encryption battle between Apple and the FBI , Apple was inspired to work toward making an unhackable future iPhones by implementing stronger security measures even the company can't hack. Even at that point the company hired one of the key developers of Signal — one of the world's most secure, encrypted messaging apps — its core security team to achieve this goal. But it seems like Apple has taken something of a backward step. Apple deliberately weakens Backup Encryption For iOS 10 With the latest update of its iPhone operating system, it seems the company might have made a big blunder that directly affects its users' security and privacy. Apple has downgraded the hashing algorithm for iOS 10 from "PBKDF2 SHA-1 with 10,000 iterations" to "plain SHA256 with a single iteration," potentially allowing attackers to brute-force the password via a standard desktop computer processor. PBKDF2 stands for Password-Based Key Deri...

Matrix Push C2 Uses Browser Notifications for Fileless, Cross-Platform Phishing Attacks

Matrix Push C2 Uses Browser Notifications for Fileless, Cross-Platform Phishing Attacks

Nov 22, 2025 Browser Security / Cybercrime
Bad actors are leveraging browser notifications as a vector for phishing attacks to distribute malicious links by means of a new command-and-control (C2) platform called Matrix Push C2. "This browser-native, fileless framework leverages push notifications, fake alerts, and link redirects to target victims across operating systems," Blackfog researcher Brenda Robb said in a Thursday report. In these attacks, prospective targets are tricked into allowing browser notifications through social engineering on malicious or legitimate-but-compromised websites. Once a user agrees to receive notifications from the site, the attackers take advantage of the web push notification mechanism built into the web browser to send alerts that look like they have been sent by the operating system or the browser itself, leveraging trusted branding, familiar logos, and convincing language to maintain the ruse. These include alerts about, say, suspicious logins or browser updates, along with ...

⚡ Weekly Recap: Firewall Flaws, AI-Built Malware, Browser Traps, Critical CVEs & More

Jan 26, 2026 Hacking News / Cybersecurity
Security failures rarely arrive loudly. They slip in through trusted tools, half-fixed problems, and habits people stop questioning. This week’s recap shows that pattern clearly. Attackers are moving faster than defenses, mixing old tricks with new paths. “Patched” no longer means safe, and every day, software keeps becoming the entry point. What follows is a set of small but telling signals. Short updates that, together, show how quickly risk is shifting and why details can’t be ignored. ⚡ Threat of the Week Improperly Patched Flaw Exploited Again in Fortinet Firewalls — Fortinet confirmed that it's working to completely plug a FortiCloud SSO authentication bypass vulnerability following reports of fresh exploitation activity on fully-patched firewalls. "We have identified a number of cases where the exploit was to a device that had been fully upgraded to the latest release at the time of the attack, which suggested a new attack path," the company said. The activi...

⚡ Weekly Recap: CI/CD Backdoor, FBI Buys Location Data, WhatsApp Ditches Numbers & More

Mar 23, 2026 Cybersecurity / Hacking
Another week, another reminder that the internet is still a mess. Systems people thought were secure are being broken in simple ways, showing many still ignore basic advisories. This edition covers a mix of issues: supply chain attacks hitting CI/CD setups, long-abused IoT devices being shut down, and exploits moving quickly from disclosure to real attacks. There are also new malware tricks showing attackers are becoming more patient and creative. It’s a mix of old problems that never go away and new methods that are harder to detect. There are quiet state-backed activities, exposed data from open directories, growing mobile threats, and a steady stream of zero-days and rushed patches. Grab a coffee, and at least skim the CVE list. Some of these are the kind you don’t want to discover after the damage is done. ⚡ Threat of the Week Trivy Vulnerability Scanner Breached in for Supply Chain Attack — Attackers have backdoored the widely used open-source Trivy vulnerability scanner, ...
Iran-Linked RedKitten Cyber Campaign Targets Human Rights NGOs and Activists

Iran-Linked RedKitten Cyber Campaign Targets Human Rights NGOs and Activists

Jan 31, 2026 Cyber Espionage / Artificial Intelligence
A Farsi-speaking threat actor aligned with Iranian state interests is suspected to be behind a new campaign targeting non-governmental organizations and individuals involved in documenting recent human rights abuses. The activity , observed by HarfangLab in January 2026, has been codenamed RedKitten . It's said to coincide with the nationwide unrest in Iran that began towards the end of 2025, protesting soaring inflation, rising food prices, and currency depreciation. The ensuing crackdown has resulted in mass casualties and an internet blackout . "The malware relies on GitHub and Google Drive for configuration and modular payload retrieval, and uses Telegram for command-and-control," the French cybersecurity company said. What makes the campaign noteworthy is the threat actor's likely reliance on large language models (LLMs) to build and orchestrate the necessary tooling. The starting point of the attack is a 7-Zip archive with a Farsi filename that contains...

ThreatsDay Bulletin: GhostAd Drain, macOS Attacks, Proxy Botnets, Cloud Exploits, and 12+ Stories

Jan 01, 2026 Cybersecurity / Hacking News
The first ThreatsDay Bulletin of 2026 lands on a day that already feels symbolic — new year, new breaches, new tricks. If the past twelve months taught defenders anything, it’s that threat actors don’t pause for holidays or resolutions. They just evolve faster. This week’s round-up shows how subtle shifts in behavior, from code tweaks to job scams, are rewriting what “cybercrime” looks like in practice. Across the landscape, big players are being tested, familiar threats are mutating, and smaller stories are quietly signaling bigger patterns ahead. The trend isn’t about one big breach anymore; it’s about many small openings that attackers exploit with precision. The pace of exploitation, deception, and persistence hasn’t slowed; it’s only become more calculated. Each update in this edition highlights how the line between normal operations and compromise is getting thinner by the week. Here’s a sharp look at what’s moving beneath the surface of the cybersecurity world as 2026 begin...

⚡ Weekly Recap: Fortinet Exploits, RedLine Clipjack, NTLM Crack, Copilot Attack & More

Jan 19, 2026 Hacking News / Cybersecurity
In cybersecurity, the line between a normal update and a serious incident keeps getting thinner. Systems that once felt reliable are now under pressure from constant change. New AI tools, connected devices, and automated systems quietly create more ways in, often faster than security teams can react. This week’s stories show how easily a small mistake or hidden service can turn into a real break-in. Behind the headlines, the pattern is clear. Automation is being used against the people who built it. Attackers reuse existing systems instead of building new ones. They move faster than most organizations can patch or respond. From quiet code flaws to malware that changes while it runs, attacks are focusing less on speed and more on staying hidden and in control. If you’re protecting anything connected—developer tools, cloud systems, or internal networks—this edition shows where attacks are going next, not where they used to be. ⚡ Threat of the Week Critical Fortinet Flaw Comes Under...
