Parcel delivery phishing campaigns appear around the world under different courier names. In the United States, the messages commonly impersonate USPS and claim that a package has an invalid address or could not be delivered. Similar messages impersonate Colissimo and Chronopost in France, Correos in Spain, Poste Italiane in Italy, and PostNL in the Netherlands. The details vary, but the aim is usually the same: to persuade you to visit a fake courier website and provide personal and financial…

Only days after Revolut acknowledged that it disclosed sensitive customer records to an unauthorized party, affected customers are receiving phishing texts. However, we don’t know yet if the phishing texts are linked to the breach. The company had accepted fraudulent information requests sent from an email address on a legitimate government agency domain. Through this social engineering attack, rather than by gaining access to Revolut’s systems, the criminals obtained the following types of…
Introduction Torrent trackers have long been abused for distributing malicious software, disguised as popular films, games, and other content. Our previous research has shown that cybercriminals repeatedly turn torrents as an initial infection vector, using trojanized cracks and installers to reach a large number of users. Installation guides for pirated software routinely instruct users to disable their antivirus, conditioning them to ignore potential threats they are inviting onto their…
Since early May 2026, we’ve been monitoring a large phishing campaign based on T-Mobile rewards points. The messages falsely warn that a customer’s rewards points are about to expire. They aren’t legitimate account notices: They use urgency, invented point balances, and phishing links to push recipients into acting before they can verify the claim. A typical message says that a T-Mobile Rewards account holds 18,400 points, gives an imminent expiry date, and states that unused points will be…

Earlier today, I noted an odd request showing up in our "First Seen" report: GET /PIAF-HMS/ HTTP/1.1 Host: [redacted] User-Agent: Farez-Sorter/1.0 Accept-Encoding: gzip This request is linked to a rather old application, a "PBX in a Flash Hospitality Management System" [1]. The last update, the addition of a license file, happened 10 years ago, and I would consider the project abandoned. However, I also noted a new vulnerability reported a couple of months ago: An SQL injection issue. A quick…
Over the past year, our Global Emergency Response Team (GERT) has investigated several incidents involving the NightEagle group (APT-Q-95).

Researchers at Hudson Rock found that cybercriminals hijacked HBO Max’s verified Reddit account and used it to run 108 malicious ads over roughly 48 hours. The ads used HBO Max’s trusted corporate account to promote fake AI tools, developer software, and macOS utilities, lowering potential victims’ guards. Some ads directed users to convincing HBO lookalike sites that claimed to offer a native HBO Max app for macOS or a promotional download. But instead of providing an installer, the sites…
Bitrefill is a legitimate company that sells gift cards for popular stores like Amazon, Deliveroo, Apple, Nintendo, and thousands of others. They also sell eSIMs, and mobile top-ups. You can pay on their website for all of these with cryptocurrency. The scam is designed to catch people searching for Bitrefill or something it sells, like a gift card. Victims see a search result that appears to lead to Bitrefill but actually points to a lookalike domain. The fake site then takes them through what…

Elastic Security Labs has tracked REF9334, a Brazilian banking malware operation, since May 2025. Its toolkit is called KREMLIN (as named by the malware author, Kr3mlin4rt1st), though nothing about the operation is Russian. Lures impersonate twelve Brazilian banks; error messages and code comments are written in Portuguese, and the operators' Ethereum transactions cluster during São Paulo working hours. Over 15 months and seven campaigns, they built a malicious browser extension that installs…

An attacker breached an email marketing platform and launched targeted attacks against the newsletter subscribers of some of its customers, especially those working in cryptocurrency and adjacent fields. The incident was a supply-chain phishing campaign carried out through Brevo, an email marketing provider used by several cryptocurrency companies and other firms. Brevo initially said an attacker had gained access to 120 customer accounts, some of which were used to send phishing emails to the…
I identified an attacker using a semi-autonomous coding agent to run an offensive operation: finding poorly secured LLM resale gateways, acquiring API access through ordinary web flaws and account farming, validating the resulting inference capacity, and aggregating it behind a single gateway of their own. What I captured was not simply credential theft, but an inference supply chain — an agent harvesting, validating, and consolidating LLM access into infrastructure that serves it again through…

BlueMoon, a shared Chrome and Windows exploit kit, shows why “patch later” is becoming a dangerous gamble. Security updates are easy to put off. The browser still opens, Windows still works, and choosing to relaunch your browser or restart your computer later can feel harmless. But a newly documented exploit kit called “BlueMoon” shows how quickly patching delays can become dangerous. Proofpoint Researchers found four espionage groups using the same exploit chain against Chrome browsers running…

Scammers are abusing Meta’s copyright-reporting system to suspend people’s Instagram accounts and then hold them for ransom, according to the BBC. Criminals file fake copyright complaints with Instagram, claiming that an account is using material it doesn’t own. Repeated complaints can trigger a temporary account suspension from the platform, locking out the victim even though they haven’t done anything wrong. The criminal then moves the conversation to another platform, such as Telegram, and…

About a week ago, Proxmox published an advisory revealing a vulnerability in older versions of Proxmox VE, its flagship Virtual Environment product. The vulnerability only affects version 7, which has not been supported for a couple of years now. But it appears that the vulnerability may have caught the attention of some attackers and researchers. We do see a bump in scans for port 8006, and also some additional brute force traffic. For example, brute force requests like: POST /api2/json/access…
