- Best practices to lock down your enterprise mail
Grab a warm drink, settle in, and let‘s level up that inbox defense!
Email Attacks Just Keep Growing Sharper
You already know spam and phishing pose annoying to dangerous risks. But the numbers reveal how extensively this menace has grown:
- 50% of organizations reported an email attack in 2022, up 22% from 2021
- Email-based ransomware attacks doubled between 2020 to 2021
- Spam emails with malicious URLs increased from 1% in 2020 to 11% by the end of 2021
- Microsoft reported spotting 10 billion email threats monthly in 2022
Why this surge? Well, a single innocent click from one employee is all it takes for cybercrooks to gain a foothold into systems housing your precious data.
And vulnerabilities introduced by remote work, cloud migrations, third-party software, social media scams, and geopolitics offer lots of ammunition. For example, look at the havoc Russia-linked Noble Baron/Cyclops Blink phishing campaign has recently caused worldwide.
That‘s why Mark Fernandes, CTO at CryptForce, stresses, "It‘s critical enterprises implement a defense-in-depth strategy against the advanced email attack techniques that bypass most native security layers."
So next, let‘s break down the common phishing hooks attackers bait your workers with before deeply diving into smart countermeasures.
Anatomy of a Phishing Expedition
While spam campaigns cast wide, indiscriminate nets aiming to lure a few bites, spear phishing efforts precisely target select high-value victims through manipulation.
And phishing tactics keep evolving more convincingly by studying our psychological vulnerabilities. Some clever schemes seen recently:
- Invoice Phishing: Spoofs legitimate payment reminders from vendors to steal bank/credit card data
- Business Email Compromise (BEC): Impersonates executives to fool staff into unauthorized wire transfers
- Gift Card Scams: Masquerades as IT Help Desk requiring gift card codes to release "locked systems"
- Malware Cargo: Infected attachments evade detection to unleash cryptominers, keyloggers, and botnet zombies
- Clickbait Subjects: Uses urgency, controversy, or headlines as lures
Once a victim takes actions like clicking booby-trapped links, entering info, downloading files, or replying, the hook sets, and adversaries reel them into compromised networks.
Costly consequences ensue – just ask the municipal Pennsylvania school district that wired $465,000 to fraudsters posing as contractors or the Singapore electronics manufacturer that lost a $23 million business deal from leaked emails.
So with hazards hiding behind every message, how do savvy IT teams detect sneaky phishing plays?
Unmasking Attacks with Email Security Solutions
Integrating a dedicated email security platform fortifies protection against infiltrating messages using a smart multilayered approach.
Stage #1: Automated Analysis & Detection
As emails hit protected servers, anti-spam engines instantly scan for fingerprints of known phishing tactics and spam traits. Signatures observed get compared against global blocklists containing over 30 million malicious URLs/IPs.
Heuristic rules also assess other suspect characteristics like formatting inconsistencies, spoofed domains, suspicious headers/content, and embedded redirects.
Refined machine learning models additionally inspect patterns like unnatural word repetitions not easily noticeable to humans. For example, tools from vendors like ValiMail and Inky apply deep learning capabilities for behavioral analysis and language processing.
Advanced solutions like Ironscales even mimic real users by engaging with phishing emails to better understand emerging methods. Automated bots extract forensic artefacts through safe analysis.
Such steps filter out and quarantine up to 90% of junk before it touches your environment.
Stage #2: Attachment Detection
Another key phase checks attachments that cybercriminals commonly weaponize as trojan vehicles. Solutions like Proofpoint isolate attachments and meticulously pick them apart using:
- Sandboxing: Runs samples in secure virtual environments observing malicious actions safely
- Static Analysis: Scans code without execution searching for known malware signatures
- Dynamic Analysis: Executes attachments while monitoring system impact for anomalies
Together, these techniques reliably uncover dangers hidden in files.
Stage #3: Authenticating Senders
Verification via SPF, DKIM, and DMARC confirms legitimate emails from expected domains. This blocks spoofing attempts from untrusted locations.
For example, Agari helped a hospitality firm flag 15,000 monthly spoofed booking confirmations pretending to be the brand.
Stage #4: Post-Delivery Defense
Protection also continues after delivery directly on employee devices, web interfaces, and company networks through AI-powered endpoint agents.
As workers interact with emails, local monitoring flags malicious links, dangerous file behaviors, and potential data exfiltration to prevent post-click hijacking.
Picking Your Best Email Security Partner
Now with strengthened insight into these B2B superheroes defending against phishing plots, how do you select an ideal champion fitting your enterprise needs?
Let‘s run through key decision criteria:
Detection Accuracy
Rigorously compare advertised detection rates and facial false positives that need administrative override during evaluations.
Favor options like Mirapoint that publish detailed anti-phishing testing results conducted by Miercom and SE Labs. This reflects real-world performance.
Total Cost
Evaluate both implementation and ongoing licensing costs across shortlisted options covering elements like:
- Per user/mailbox pricing
- Setup and customization fees
- Premium features pricing
- Required hardware investments
- Training and deployment needs
Platforms like SpamTitan shine here with transparent pricing and no long-term contracts.
Internal Resource Impact
Consider how much staff effort gets required for daily operations like monitoring alerts, quarantine management, creating allow/block lists, email restoration, upgrades, and reporting.
Luckily, set-and-forget cloud solutions like Proofpoint minimize this load by handling everything backend.
Scalability & Availability
As your enterprise grows in size and apps, assess each contender‘s ability to seamlessly scale protection across web interfaces, devices, and global regions without choking points.
Architectures like Mimecast promote resiliency with distributed, load-balanced processing pipelines.
