Google has devoted a safety analysis workforce to discovering loopholes that allow hackers to extort customers. The Challenge Zero workforce discovered a vulnerability in Samsung Exynos modems. Evidently, these modems are utilized in completely different smartphones, together with the Pixel 6, 7, and a few Galaxy telephones just like the Galaxy S22 and A53.
In a weblog put up, the workforce reveals that the Exynos modems have severe vulnerabilities. What’s extra, these vulnerabilities will help cyber attackers in having access to customers’ smartphones on the baseband degree with none consumer interplay. All they want is the consumer’s cellphone quantity, and they’re good to go. Samsung has to do one thing to repair this, and I believe it’s on its method to fight these points.
Skilled Hackers Can Successfully Exploit Samsung Samsung Modem Vulnerabilities…
The Challenge Zero workforce warns the Galaxy cellphone maker {that a} skilled hacker can simply exploit the difficulty. Most significantly, the hacker doesn’t want any high-resolution approach however restricted extra analysis and improvement.
Google claims that this month’s safety patch will certainly repair the issue. Nonetheless, its flagship units, together with Google Pixel 6, 6 Professional, and 6A, is not going to obtain the safety patch. When you’ve got one of many following units, you’re susceptible to changing into a sufferer:
- Galaxy A04, A12, A13, A21, A33, A71, M12, M33, M13, and S22 collection.
- Vivo X30, X60, X70, S6, S15 and S16 collection.
Apart from this, your good autos and wearables are in danger if they’re powered by the Exynos Auto T5123 or Exynos W920 chipsets. Most significantly, hackers might want to use one of many affected Samsung Exynos modems to get into the units.

I listed the S22 collection within the checklist, however there’s a slight signal of aid for Samsung Galaxy S22 house owners. The reason being that units outdoors Europe and a few African nations use Qualcomm chipsets; due to this fact, they’re secure.
Nonetheless, most mid-range Samsung smartphones, such because the A53 and European S22 collection, are weak to hacking makes an attempt. S21 and S23 are secure as main Samsung flagship units characteristic Qualcomm processors.
How To Shield Your self From These Vulnerabilities?
In whole, Google’s workforce discovered 18 vulnerabilities, and these aren’t minor ones that may be simply exploited. The Challenge Zero workforce suggests customers flip off Wi-Fi calling and Voice-over-LTE. Historically, safety researchers wait till a repair is obtainable, nevertheless it’s too early to disclose this time.
That offers hackers loads of time to benefit from this exploit. Maddie Stone, a Challenge Zero researcher, tweeted, “Finish customers nonetheless don’t have patches 90 days after the report.” Which means smartphone producers must cope with these exploits on their very own.
In numbers, there are practically 18 vulnerabilities in Samsung Exynos modems, and 4 of them are extremely extreme. These 4 can permit “Web-to-baseband distant code execution,” and Google says there isn’t a repair for this in the mean time. It is usually not sharing any extra data.
All the opposite vulnerabilities are minor, requiring “both a malicious cellular operator or an attacker with native entry to the machine.” General, these aren’t good indicators for Samsung, as the corporate is engaged on advertising and marketing its Exynos chips for a higher objective.
