When Multi-Factor Authentication Stops Being Enough
For most Algerian businesses, turning on multi-factor authentication (MFA) has felt like the finish line of an identity-security project. Add a code from an app or an SMS on top of the password, and the account is safe. That assumption is now wrong in a specific and dangerous way — and the data behind it is stark.
According to Flashpoint’s Global Threat Intelligence Index midyear edition, reported by Infosecurity Magazine, infostealer malware harvested 1.8 billion credentials in the first six months of 2025, an 800% increase over the prior six months, drawn from 5.8 million infected hosts. By the close of the year, Flashpoint’s 2026 Global Threat Intelligence Report counted over 11.1 million machines infected with infostealers and 3.3 billion compromised credentials and cloud tokens. Its single most important sentence for any Algerian IT manager reads: “The fundamental mechanics of cybercrime have shifted from breaking in to logging in, as attackers leverage stolen session cookies to behave like legitimate users.”
That shift is the heart of the problem. MFA protects the moment you log in — but not the session that follows it.
How a Stolen Cookie Walks Straight Past Your MFA
When a staff member signs into a web application — Microsoft 365, Google Workspace, a banking portal, an internal dashboard — and completes the MFA challenge, the application issues a session cookie. The browser stores that cookie and presents it on every subsequent request. As the technical breakdown from WhiteIntel explains, the application then “trusts this session token without re-validating credentials.” MFA only protected the entry door; the cookie is a key that the door-checker no longer inspects.
An infostealer — often delivered through a cracked software download, a malicious browser extension, or a phishing lure — does not try to crack the password or defeat MFA. It simply copies that session cookie out of the browser’s storage and ships it to the attacker. The attacker loads the cookie into their own browser and, as WhiteIntel puts it, “the application serves them as if they were the user.” No password prompt. No MFA push. Nothing for the victim to notice.
This is why session theft is now its own threat category. Security Magazine’s analysis of the four identity gaps attackers exploit reports that nearly one in three incidents now involves credential theft, with infostealer delivery rising 84% year-over-year. The piece is blunt that “MFA bypass” is a misnomer — the MFA worked correctly; the attacker simply stole the artifact issued after it succeeded.
The scale of the cookie-theft economy is its own warning. Constella’s 2026 Identity Breach Report, summarized by industry coverage, found that infostealers processed 51.7 million data packages in 2025, a 72% year-over-year rise — and that those packages are especially dangerous precisely because they carry live session cookies that bypass MFA entirely.

Why This Lands Hard in Algeria
Algeria’s digital footprint is now large enough that this threat is a present-tense risk, not a foreign abstraction. DataReportal’s Digital 2025 Algeria report counted 36.2 million internet users at the start of 2025, a 76.9% penetration rate. Every one of those users who logs into a work account from a personal laptop, a shared family computer, or a machine running cracked software is a potential cookie-theft entry point.
Two local realities sharpen the exposure. First, the widespread use of unlicensed and cracked software — a common cost-saving habit in small firms — is one of the most reliable infostealer delivery channels, because the “crack” is frequently the malware. Second, many Algerian SMBs lack a managed device fleet, so staff log into business systems from personal hardware the company has no visibility into. A stolen cookie from a home machine is indistinguishable, to the application, from a legitimate office login.
The good news: the defenses below are configuration and discipline, not expensive tooling. They are within reach of a small IT team or even a single competent administrator.
What Algerian IT Teams Should Do
1. Turn on device-bound session credentials wherever your platform offers them
The strongest structural defense is to make a stolen cookie useless on any device other than the one it was issued to. Google made Device Bound Session Credentials (DBSC) generally available in Chrome on Windows on April 10, 2026, cryptographically tying a session to the device’s Trusted Platform Module (TPM) so the private key “cannot be exported” and a copied cookie quickly becomes worthless. If your organization uses Google Workspace, enable session binding from the admin console; if you use Microsoft 365, the equivalent is token protection and continuous access evaluation. Do not wait for a breach to flip these switches — they are off by default and cost nothing. The one caveat from WhiteIntel: device-binding coverage is still “only partial across SaaS in 2026,” so treat it as one layer, not the whole wall.
2. Shorten session lifetimes and force re-authentication on sensitive actions
A stolen cookie is only valuable while it is still valid. Reduce the window. Configure your identity provider to expire web sessions after a few hours rather than weeks, and require a fresh login — not just a valid cookie — before high-impact operations such as changing payment details, exporting customer data, or adding an administrator. WhiteIntel recommends exactly this layering: short session lifetimes plus “conditional re-authentication” for sensitive operations. For an Algerian SMB, the practical setting is a daily re-login for staff and step-up MFA on any financial or admin action. This single change can turn a successful cookie theft from a month-long breach into a few-hour nuisance.
3. Trigger MFA on anomalies, not just at login
Most identity platforms can prompt for re-authentication when a session suddenly appears from a new device, a new network, or an unexpected location. Turn this on. As Security Magazine notes, defenses against post-authentication token theft include “detection of sessions originating from new networks or devices” and continuous access evaluation. In practice, that means a cookie stolen from an employee in Oran and replayed by an attacker on a foreign IP address triggers a challenge the attacker cannot answer. Pair this with alerting so your IT lead is notified, not just the end user — attackers count on a confused employee dismissing the prompt.
4. Make browser hygiene a written policy, not a suggestion
Because infostealers arrive through the browser and the desktop, the human layer is decisive. Ban cracked and unlicensed software on any machine used for work — this is the single highest-value rule, since pirated installers are a primary infostealer vector. Restrict browser extensions to a reviewed allow-list, since malicious extensions read cookies directly. Require that work accounts are only accessed from machines with up-to-date operating systems and active anti-malware. For staff using personal devices, mandate a separate browser profile (or a dedicated work browser) so a compromise of personal browsing does not automatically expose work session cookies.
The Structural Lesson
The deeper message in the 2025–2026 data is that identity has become the perimeter, and the perimeter has a gap that passwords and MFA alone do not cover. Flashpoint’s framing — cybercrime moving “from breaking in to logging in” — is not a slogan; it is an instruction to redesign defenses around the session, not just the login. For Algerian organizations, the encouraging part is that the most effective countermeasures are policy and configuration choices already available in the platforms they use every day: device-bound sessions, shorter token lifetimes, anomaly-triggered MFA, and enforced browser hygiene. None of these require a dedicated security operations center or a large budget. The teams that adopt them now will treat a stolen cookie as a contained incident; the teams that assume MFA is the finish line will keep discovering that an attacker has been logged in as their staff for weeks.
Frequently Asked Questions
What is session cookie theft and how does it bypass MFA?
A session cookie is the token a web application issues to your browser after you successfully log in and pass MFA, so it does not ask for your password again on every page. Infostealer malware copies that cookie from the browser and sends it to an attacker, who loads it into their own browser and is served as if they were you — no password or MFA prompt required. The MFA worked correctly; the attacker simply stole the artifact issued once it succeeded.
Are Algerian businesses actually at risk, or is this a Western problem?
The risk is global and present in Algeria. Algeria had 36.2 million internet users at the start of 2025, and the country’s common reliance on personal devices and unlicensed software — a frequent infostealer delivery channel — makes local exposure higher, not lower. Any staff member logging into a work account from a compromised personal or home machine can have their session cookie stolen.
What is the single most effective defense a small Algerian team can deploy?
Enabling device-bound session credentials (session binding in Google Workspace, token protection in Microsoft 365) is the strongest structural fix, because it makes a stolen cookie useless on any other device. If that is not yet available for your platform, the highest-value low-cost step is banning cracked software on work machines and shortening session lifetimes to a few hours, which dramatically limits how long a stolen cookie remains usable.
