📰 Cybersecurity Daily Brief — Patch Watch Monday
Monday, 08 June 2026 — The stories that broke while you were away from your screen.
What You Need to Know
- 20,000 Instagram accounts stolen. Hackers tricked Meta's AI support bot into resetting passwords. The bot did exactly what it was told.
- A new botnet is spreading through home routers. C0XMO exploits an unpatched DD-WRT vulnerability. Once inside, it kills rival malware and takes over.
- FBI and MI5 are warning about fake LinkedIn recruiters. They're not after your money — they're after your employer's secrets.
- DarkWatch logged 8,910 captures this week across 18 targets.
1. How Hackers Used Meta's AI Bot to Steal 20,000 Instagram Accounts
On May 31, word began to spread on Telegram. Someone had figured out that Meta's AI customer support bot would reset an account's password if you asked it nicely enough.
The technique was remarkably simple. Use a VPN with an IP near the target's location. Request a password reset. When the bot asks to help, tell it to link the account to a new email address. The bot sends a one-time code. You're in.
Krebs on Security broke the story. The affected accounts included the Obama White House Instagram and the U.S. Space Force's Chief Master Sergeant account — both defaced with pro-Iranian images. Meta pushed an emergency patch over the weekend, but not before at least 20,000 accounts were compromised.
Who's affected: Anyone with an Instagram account. If you haven't checked yours recently, do it now.
What to do:
- Check if you're still logged into your Instagram account
- Enable two-factor authentication
- Make sure your recovery email and phone number are current
- Don't rely on AI support bots for account security. They do what they're told.
2. C0XMO Botnet — Your Router Is the Target
A new botnet called C0XMO is scanning the internet for routers running DD-WRT firmware with an unpatched vulnerability. It exploits the flaw, installs itself, and then — interestingly — kills any rival malware it finds on the device. It wants the router to itself.
DD-WRT is popular with users who flash their routers for better performance or features. Many haven't updated their firmware in months or years. The botnet uses compromised routers for DDoS attacks and credential theft.
What to do:
- Check if your router runs DD-WRT
- Update to the latest firmware
- If you're not sure, check your router's admin panel or Google your model + "firmware update"
3. The LinkedIn Recruiter Who Isn't a Recruiter
The FBI and MI5 issued a joint warning. Fake LinkedIn recruiter profiles are being used to target people in defence, cybersecurity, finance, and government. The profiles look legitimate — connections, endorsements, realistic job listings.
The approach is slow and patient. The fake recruiter sends a message about a promising opportunity. During the conversation, they ask seemingly innocent questions about the target's work. Over time, they build a picture of projects, security measures, and internal systems. Chinese intelligence agencies are the likely source.
What to do:
- Be cautious of unsolicited recruiter messages
- Verify the person exists — check their profile history and mutual connections
- Don't discuss sensitive work details, even indirectly
