Last month, the makers of one of the most promising coronavirus vaccines reported that hackers stole confidential documents they had submitted to a European Union regulatory body. On Friday, word emerged that the hackers have falsified some of the submissions’ contents and published them on the Internet.

Studies of the BNT162b2 vaccine jointly developed by pharmaceutical companies Pfizer and BioNTech found it’s 95 percent effective at preventing COVID-19 and is consistently effective across age, gender, race, and ethnicity demographics. Despite near-universal consensus among scientists that the vaccine is safe, some critics have worried it isn’t. The hackers appear to be trying to stoke those unsupported worries.

Data unlawfully accessed by the hackers “included internal/confidential email correspondence dating from November, relating to evaluation processes for COVID-19 vaccines,” the European Medicines Agency based in Amsterdam said in a statement. “Some of the correspondence has been manipulated by the perpetrators

DNS over HTTPS is a new protocol that protects domain-lookup traffic from eavesdropping and manipulation by malicious parties. Rather than an end-user device communicating with a DNS server over a plaintext channel—as DNS has done for more than three decades—DoH, as DNS over HTTPS is known, encrypts requests and responses using the same encryption websites rely on to send and receive HTTPS traffic.

Using DoH or a similar protocol known as DoT—short for DNS over TLS—is a no brainer in 2021, since DNS traffic can be every bit as sensitive as any other data sent over the Internet. On Thursday, however, the National Security Agency said in some cases Fortune 500 companies, large government agencies, and other enterprise users are better off not using it. The reason: the same encryption that thwarts malicious third parties can hamper engineers’ efforts to secure their networks.

“DoH provides the benefit of

Google researchers have detailed a sophisticated hacking operation that exploited vulnerabilities in Chrome and Windows to install malware on Android and Windows devices.

Some of the exploits were zero-days, meaning they targeted vulnerabilities that at the time were unknown to Google, Microsoft, and most outside researchers (both companies have since patched the security flaws). The hackers delivered the exploits through watering-hole attacks, which compromise sites frequented by the targets of interest and lace the sites with code that installs malware on visitors’ devices. The boobytrapped sites made use of two exploit servers, one for Windows users and the other for users of Android.

Not your average hackers

The use of zero-days and complex infrastructure isn’t in itself a sign of sophistication, but it does show above-average skill by a professional team of hackers. Combined with the robustness of the attack code—which chained together multiple exploits in an efficient manner—the campaign

Email management provider Mimecast said that hackers have compromised a digital certificate it issued and used it to target select customers who use it to encrypt data they sent and received through the company’s cloud-based service.

In a post published on Tuesday, the company said that the certificate was used by about 10 percent of its customer base, which—according to the company—numbers about 36,100. The “sophisticated threat actor” then likely used the certificate to target “a low single digit number” of customers using the certificate to encrypt Microsoft 365 data. Mimecast said it learned of the compromise from Microsoft.

Certificate compromises allow hackers to read and modify encrypted data as it travels over the Internet. For that to happen, a hacker must first gain the ability to monitor the connection going into and out of a target’s network. Typically, certificate compromises require access to highly fortified storage devices that

By now, you may have heard of the hacker who says she scraped 99 percent of posts from Parler, the Twitter-wannabe site used by Trump supporters to help organize last Wednesday’s violent insurrection on Capitol Hill. What you may not know yet is the abysmal coding and security that made the scraping so easy.

To recap, the scraping was pulled off by a hacker who goes by the handle donk_enby. She originally set out to archive content posted to Parler last Wednesday in hopes of preserving self-incriminating material before account holders came to their senses and deleted it. By Sunday, donk_enby said she had collected roughly 80 terabytes of posts, including more than 1 million videos, many of which contained the GPS metadata identifying the exact locations of where the videos were shot.

“For the journalists DMing me to ask, in non-technical terms, I’d describe the

If you’re using an Android device—or in some cases an iPhone—the Telegram messenger app makes it easy for hackers to find your precise location when you enable a feature that allows users who are geographically close to you to connect. The researcher who discovered the disclosure vulnerability and privately reported it to Telegram developers said they have no plans to fix it.

The problem stems from a feature called People Nearby. By default, it’s turned off. When users enable it, their geographic distance is shown to other people who have it turned on and are in (or are spoofing) the same geographic region. When People Nearby is used as designed, it’s a useful feature with few if any privacy concerns. After all, a notification that someone is 1 kilometer or 600 meters away still leaves stalkers guessing where, precisely, you are.

Stalking made simple

Independent researcher Ahmed Hassan, however,
