New details emerge of how North Korean-linked APT won trust of experts and exploited Visual Studio to infect systems with ‘Comebacker’ malware.

Apple has made structural improvements in iOS 14 to block message-based, zero-click exploits.

This essay makes the point that actual computer hackers would be a useful addition to NATO wargames:

The international information security community is filled with smart people who are not in a military structure, many of whom would be excited to pose as independent actors in any upcoming wargames. Including them would increase the reality of the game and the skills of the soldiers building and training on these networks. Hackers and cyberwar experts would demonstrate how industrial control systems such as power supply for refrigeration and temperature monitoring in vaccine production facilities are critical infrastructure; they’re easy targets and should be among NATO’s priorities at the moment.

Diversity of thought leads to better solutions. We in the information security community strongly support the involvement of acknowledged nonmilitary experts in the development and testing of future cyberwar scenarios. We are confident that independent experts, many of whom see sharing their skills as public service, would view participation in these cybergames as a challenge and an honor.

New research:

Pile driving occurs during construction of marine platforms, including offshore windfarms, producing intense sounds that can adversely affect marine animals. We quantified how a commercially and economically important squid (Doryteuthis pealeii: Lesueur 1821) responded to pile driving sounds recorded from a windfarm installation within this species’ habitat. Fifteen-minute portions of these sounds were played to 16 individual squid. A subset of animals (n = 11) received a second exposure after a 24-h rest period. Body pattern changes, inking, jetting, and startle responses were observed and nearly all squid exhibited at least one response. These responses occurred primarily during the first 8 impulses and diminished quickly, indicating potential rapid, short-term habituation. Similar response rates were seen 24-h later, suggesting squid re-sensitized to the noise. Increased tolerance of anti-predatory alarm responses may alter squids’ ability to deter and evade predators. Noise exposure may also disrupt normal intraspecific communication and ecologically relevant responses to sound.

Press release.

As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered.

Apple has added added security features to mitigate the risk of zero-click iMessage attacks.

Apple did not document the changes but Groß said he fiddled around with the newest iOS 14 and found that Apple shipped a “significant refactoring of iMessage processing” that severely cripples the usual ways exploits are chained together for zero-click attacks.

Groß notes that memory corruption based zero-click exploits typically require exploitation of multiple vulnerabilities to create exploit chains. In most observed attacks, these could include a memory corruption vulnerability, reachable without user interaction and ideally without triggering any user notifications; a way to break ASLR remotely; a way to turn the vulnerability into remote code execution;; and a way to break out of any sandbox, typically by exploiting a separate vulnerability in another operating system component (e.g. a userspace service or the kernel).

The unprecedented volume of unemployment insurance fraud witnessed in 2020 hasn’t abated, although news coverage of the issue has largely been pushed off the front pages by other events. But the ID theft problem is coming to the fore once again: Countless Americans will soon be receiving notices from state regulators saying they owe thousands of dollars in taxes on benefits they never received last year.

One state’s experience offers a window into the potential scope of the problem. Hackers, identity thieves and overseas criminal rings stole over $11 billion in unemployment benefits from California last year, or roughly 10 percent of all such claims the state paid out in 2020, the state’s labor secretary told reporters this week. Another 17 percent of claims — nearly $20 billion more – are suspected fraud.

California’s experience is tracked at a somewhat smaller scale in dozens of other states, where chronically underfunded and technologically outdated unemployment insurance systems were caught flat-footed by an avalanche of fraudulent claims. The scammers typically use stolen identity data to claim benefits, and then have the funds credited to an online account that they control.

States are required to send out 1099-G forms reporting taxable income by Jan. 31, and under federal law unemployment benefits are considered taxable income. Unfortunately, many states have not reconciled their forms with confirmed incidences of fraudulent unemployment insurance claims, meaning many people are being told they owe a great deal more in taxes than they actually do.

In a notice posted Jan. 28, the U.S. Internal Revenue Service urged taxpayers who receive forms 1099-G for unemployment benefits they didn’t actually get because of ID theft to contact their appropriate state agency and request a corrected form.

But the IRS’s advice ignores two rather inconvenient realities. The first is that the same 1099-G forms which states are sending to their citizens also are reported to the IRS — typically at the same time the notices are mailed to residents. The other is that many state agencies are completely overwhelmed right now.

Karl Fava, a certified public accountant in Michigan, told KrebsOnSecurity two of his clients have received 1099-G forms from Michigan regarding thousands of dollars in unemployment payments that they had neither requested nor received.

Fava said Michigan recently stood up a website where victims of unemployment insurance fraud who’ve received incorrect 1099-Gs can report it, but said he’s not confident the state will issue corrected notices before the April 15 tax filing deadline.

“In both cases, the recipients contacted the state but couldn’t get any help,” Fava said. “We’re not getting a lot of traction in resolving this issue. But the fact that they’ve now created a web page where people can input information about receiving these tells you they have to know how prevalent this is.”

Fava said for now he’s advising his clients who are dealing with this problem to acknowledge the amount of fraudulent income on their federal tax returns, but also to subtract an equal amount on the return and note that the income reported by the state was due to fraud.

“That way, things can be consistent with what the IRS already knows,” Fava said. “Not to acknowledge an issue like this on a federal return is just asking for a notice from the IRS.”

The Taxpayer Advocate Service, an independent office of the U.S. Internal Revenue Service (IRS) that champions taxpayer advocacy issues, said it recently became aware that some taxpayers are receiving 1099-Gs that include reported income due to unemployment insurance identity theft. The office said it is hearing about a lot of such issues in Ohio particularly, but that the problem is happening nationally.

Another perennial (albeit not directly related) identity theft scourge involving taxes each year is refund fraud. Tax refund fraud involves the use of identity information and often stolen or misdirected W-2 forms to electronically file an unauthorized tax return for the purposes of claiming a refund in the name of a taxpayer.

Victims usually first learn of the crime after having their returns rejected because scammers beat them to it. Even those who are not required to file a return can be victims of refund fraud, as can those who are not actually due a refund from the IRS.  

The best way to avoid tax refund fraud is to file your taxes as early possible. This year, that date is Feb. 12. One way the IRS has sought to stem the flow of bogus tax refund applications is to issue the IP PIN, which is a six-digit number assigned to taxpayers that helps prevent the use of their Social Security number on a fraudulent income tax return. Each PIN is good only for the tax year for which it was issued.

Until recently the IRS restricted who could apply for an IP PIN, but the program has since been opened to all taxpayers. To create one, if you haven’t already done so you will need to plant your flag at the IRS by stepping through the agency’s “secure access authentication” process.

Creating an account requires supplying a great deal of personal data; the information that will be requested is listed here.

The signup process requires one to validate ownership of a mobile phone number in one’s name, and it will reject any voice-over-IP-based numbers such as those tied to Skype or Google Voice. If the process fails at this point, the site should offer to send an activation code via postal mail to your address on file.

Once you have an account at the IRS and are logged in, you can request an IP PIN by visiting this link and following the prompts. The site will then display a six digit PIN that needs to be included on your federal return before it can be accepted. Be sure to print out a copy and save it in a secure place.
